ANNUAL REPORT 2010 – KEY IT INDICATORS

1. INTRODUCTION 1.1 History Instituto de Telecomunicações (it) is a private, not-for-profit organisation, an association of eight institutions with research and development in the field of Telecommunications: • Instituto Superior Técnico (IST); • Universidade de Aveiro (UA); • Faculdade de Ciências e Tecnologia da Universidade de Coimbra (FCTUC); • Portugal Telecom Inovação, (PTIn); • Nokia Siemens Networks S.A (NSN); • Universidade da Beira Interior (UBI); • Universidade do Porto (UP); • Instituto de Ciências do Trabalho e da Empresa — Instituto Universitário de Lisboa (ISCTE-IUL). it is organised around three sites: one in Aveiro, in the University Campus, another in Coimbra, in Site II of the University of Coimbra and the third one in Lisbon, in Instituto Superior Técnico. In addition there are four delegations: • Covilhã, in the University of Beira Interior; • Leiria, inthe “Escola Superior de Tecnologia e Gestão” of the Leiria Polytechnic (IPL); • Lisboa, in Instituto Superior de Ciências do Trabalho e da Empresa (ISCTE); • Porto, shared by the Faculty of Engineering and the Faculty of Sciences of the University of Porto. Setting up of it was the result of a 1.5 billion escudos (about 7.5 million Euros) grant from Programme CIENCIA, through three contracts signed in 1991. This investment enabled new infrastructures to be built and research laboratories to be equipped at each site. Installation was concluded in Aveiro in 1993 and in Lisbon and Coimbra in 1994. Since 1993, it activities proceed regularly.

ANNUAL REPORT 2010 – KEY IT INDICATORS

it bylaws statutes were first approved in 1992, modified in 1997 and modified again in 2003. New site bylaws deriving from it bylaws were approved and implemented in 2005. Key developments in 2010 are highlighted ahead. Details are included in the sections dealing with each of the research areas.

1.2 Management it is managed by a Board of Directors, elected by the General Assembly, and by Site Management Boards, which include the site members of the Board of Directors. Site Management Boards enjoy ample freedom to deal with current affairs and usually meet weekly. The Board of Directors meets at least once a month. it scientific activities are overseen by the Scientific Board, which includes all it researchers holding a Ph.D. degree. The Scientific Board meets in Plenary or in Committees,

both

permanent

and

temporary.

There

are

two

permanent

committees: the Science and Technology Committee and the Research Group Coordination Committee. it Work Plan and the Annual Report are discussed with the Advisory Committee, formed by three independent experts in the field of telecommunications (Prof. Sir John O’Reilly, Prof. Martin Tomlinson and Dr. Roland Huber) acting in a personal capacity, and together with the Accounts (after legal certification) are subsequently submitted to the General Assembly for approval. The General Assembly met formally twice in 2010. The first meeting was held on the 31st of May, in the Meeting Room of the Aveiro site, to discuss and approve the 2009 Annual Report and Accounts and to empower the Board of Directors to create an it External Laboratory in Taguspark. The second meeting took place on the 22nd of December, in the Chancellor Room of Porto University Club (Círculo Universitário do Porto), to discuss and vote on the admission of the University of Porto and the Instituto de Ciências do Trabalho e da Empresa — Instituto Universitário de Lisboa as members of it and to discuss and vote on the Work Plan and Budget for 2011.

ANNUAL REPORT 2010 – KEY IT INDICATORS

The Research Group Coordination Committee also met twice during 2010. On the first meeting, held on the 19th of May, at Hotel D. Luis, Coimbra. Draft Proposal of the 2009 Annual Report, was discussed and received a favourable opinion. The reorganization of it Groups, a subject of growing importance since the original group structure dates from 1993 and since then the number of it researchers has more than tripled. The document “A policy for quality” was also discussed in order to consider if publications in conferences should be included in the calculation of the productivity index of it researchers. No conclusion was reached and the subject should be discussed again. On the second meeting, held on the 6th of December, in the Aveiro site conference room, the Work Plan and Budget for 2011, was discussed and received a favourable opinion. Principal investigators of the internal projects from the second call presented and discussed their achievements. The subject of group reorganization was further discussed and the Board of Directors was committed to put forward a proposal, taking into account all contributions, at the next meeting of the Research Group Coordination Committee.

1.3 Highlights of 2010 Like 2009, for many reasons, 2010 was again a very good year for it apart from funding. Firstly, the scientific output remained high: • 55 books and bookchapters; • 244 papers in international refereed scientific journals; • 15 patent requests; • 498 papers in refereed conferences, with published proceedings. Secondly, fostering of advanced education, although somewhat lower than in 2009 was substantial: • 26 PhD theses, submitted and approved; • 169 MSc theses, submitted and approved.

ANNUAL REPORT 2010 – KEY IT INDICATORS

Funding for 2010 was only received in January 2011 and therefore it had to manage with the remaining of 2009 funding, whose execution period was extended, firstly up to the 30th of June 2010, and later to the 31st of December 2010, because about 40% of the programmatic funding for 2009 (≈ 800 k€) was only received in August 2010. Finally it, together with the other two Associate Laboratories in the field of Information and Communication Technologies (INESC-ID and INESC-Porto), was evaluated in 2010, solely based on the information provided in FCT forms. The first evaluation report, even if it concluded that it should continue as an Associate Laboratory, had major factual errors, which were promptly pointed out by it. Somewhat surprisingly, one of the four members of the evaluator panel sent (to it, INESC-ID, INESC-Porto) his expert opinion that, in essence, contradicted the previous evaluator panel opinion. Confronted with this rather bizarre situation FCT has decided to order another evaluation, the results of which are not yet known.

The number of PhD students, whose scholarships are almost all funded by FCT, in 2010 was almost identical to the number in 2009. reaching an all time level. This is an important step in improving it performance and impact. In addition to the 224 PhD scholarships mostly funded by FCT, it hosted 19 young students under FCT scholarships for initiating scientific activity, plus 504 BSc, MSc and post-doc fellowships (corresponding to 378 grantees) in ongoing projects and 5 in mobility fellowships associated with the CMU-Portugal Program. During 2010, 146 nationally funded and 35 internationally funded projects were active, as shown in section 2.2. It is particularly noteworthy the fact that on the 31st of December it was involved in 29 FP7 projects (running and selected for funding) in addition to other 7 projects, where there was involvement of some it researchers from the Lisbon site. During 2010 it continued to manage the logistics of the CMU-Portugal program by special contract with FCT.

it is a member of the CIENCIA VIVA, the National Agency for Scientific and Technological culture and co-operates in some of its events, namely those related with the diffusion of know-how on electromagnetic radiation and its effects on the human body. Project MONIT, (www.lx.it.pt/monit) is actively engaged in promoting and diffusing know how on electromagnetic radiation and mobile communications. Occasionally, through this project, it offers two week training in the measurement of electromagnetic radiation. In cooperation with IST, it started a one-year post graduation course in Telecommunications and Information Technologies. Sponsored by VODAFONE and in cooperation with IST, it organized and implemented a 30-hour update course in Telecommunication Systems for high school teachers which was run once in 2010 (30 teachers). Also in cooperation with IST, it organized visits and demonstrations for high school pupils, involving about 700 pupils (in 2010). Some of the activities mentioned in detail in Annexes are closely interconnected with activities carried out by it researchers in the scope of their universities or polytechnics. Their inclusion in this Report is merely for the record.

2. KEY IT INDICATORS Human Resource In 2010 it human resources included 875 people distributed as follows: • • • • •

236 researchers, 224 PhD students, 378 grantees, 15 technical, 22 administrative.

All researchers but 2, hold a PhD degree. The distribution of all human resources between the three sites is represented graphically in Figure 2.1. It is obvious from this figure that the ratios between PhD students and researchers and grantees and researchers is much higher in Aveiro than in Lisbon a fact that is partly explained by the much higher involvement of Aveiro in FP7 projects.

Figure 2.1: Distribution of it human resources between the three sites

16

ANNUAL REPORT 2010 – KEY IT INDICATORS

The distribution of researchers and PhD students between sites and delegations is shown in Figure 2.2. One must bear in mind that the 15 PhD students shown in figure as belonging to the Leiria delegation, because they are all assistants of IPL, as PhD students, they “belong to” FCTUC (14) and UA (1). This figure shows, more than the previous one, the lower proportion of PhD students in relation to the number of researchers in the IST site and, even more seriously, in the ISCTE delegation.

Figure 2.2: Distribution of itresearchers and PhD students amongmain sitesand delegations

Unfortunately our accounting systems only provides site information for grantees and thus it is not yet possible to have a more detailed picture of grantees distribution.

ANNUAL REPORT 2010 – KEY IT INDICATORS

As a result of the application it quality policy, from the 234 researchers holding a PhD Degree, 50 were excluded from FCT basic funding, and 12 had a 25 % reduction of FCT basic funding. As a result in the first semester of 2011 it has 178.25 eligible researchers. The distribution of it administrative staff is shown on Figure 2.3.

The scientific productivity in 2010 was 1.36 journal papers per eligible researcher or, counting each book, bookchapter and journal paper as one publication, 1.67 publications per eligible researcher. It is interesting to compare the distrubution of the number of researchers per site and delegation with the number of number of published works (papers in international journals and communications to refereed conferences). One should note that the sum of the number of publications per site and/or delegation is higher than the number of publications for it because asignificant number of publications (about 30 %) are authored by researchers from more than one site and/or delegation. This fact in itself is an important indicator that it is increasingly operating as a unity rather than as a collection of research units.

ANNUAL REPORT 2010 – KEY IT INDICATORS

Even if Figures 2.5 to 2.11 are self explanatory it is interesting to remark that at the level of papers in journals, site distribution follows very closely research distribution. Differences are slight at the level of communications to conferences and considerable at the number of patents where the importance of PT Inovação and Nokia Siemens Networks in Aveiro shines. Going into delegations, some differences are rather more striking, particularly at the level of papers in journals, which could not be seen at the site level and at communications in conferences that disappears at the level fo delegations.

4.1.3.2 Antenna analysis and design Work on antennas followed three main streams: small antennas for indoor applications,

antennas

for

applications

and

antennas

for

mm-wave

applications. Small terminal antennas Work continued on the design of UWB antennas for indoor personal communications and for indoor localization applications. Compact slot antennas and dielectric loaded printed monopoles have been designed and tested. A new wideband compact slot antenna array for indoor WLAN Access Points was developed, covering several wireless communications services from 2.4 to 4.8 GHz, especially designed to enhance MIMO system capacity and providing both spatial and frequency diversity. Experimental evaluation of the array performance was performed for MIMO systems, using measured channel characterization based on a previously developed MIMO testbed. Small and compact multiband microstripelements and arrays have been developed for

small

multi-standard

applications.Studies

included

investigating

antenna-user interactions and the evaluation of mutual coupling and correlation. Antenna geometries included single and multi-feed patches with slots. Electro-textile printed slot antennas for body-implanted networks have been designed and tested. Antenna configurations include a monopole like element and a rectangular slot with a triangular transition on a ground plane. Improvement of antenna radiation and efficiency have been achieved using an EBG inspired structures. 35

ANNUAL REPORT 2010 – WIRELESS COMMUNICATIONS

RFID Antennas Following work on this topic in previous years, work continued on reader antennas and tags. A passive UHF tag configuration for suitcase identification and tracking in airport handling applications was designed using a folded dipole with orthogonal arms, appropriate for integration into the wall of injection molded suitcases during fabrication process. Reader antennas for tag detection in self confined volumes covering simultaneously all the world assigned RFID sub-bands at UHF have been designed. The proposed configuration has been integrated with bookshelves, conveyor belt systems and proximity point readers. A transparent RFID reader antenna for integration into mirrors of cabinet rooms in apparel stores has been designed and demonstrated, including the related middleware. New developments were achieved on UWB antennas for localization applications. A testbed was developed to evaluate the new developed printed slot antennas and new algorithms for indoor localization that have improved accuracy to centimeter scale. On the same topic, the RMOM group in Aveirohas started to evaluate alternative antennas for indoorlocation, mainly focused on angle of arrival, where several antennas weredesigned and are being tested. Moreover a strong effort has also been puton reducing power consumption on the mobile tag, which is being achievedvia improved protocols, but also via reducing power consumption. Antennas for short range communications New antennas weredeveloped for DSRC, Vehicular communications, among vehicles and

(DSRC), which arein great development with the aim of reduce the traffic problems and improve the road safety. One study was based on the development of asolution

36

to an antenna to be used in the mobile module, usually namedOn-Board Unit (OBU). Another possibility was the design of an antenna forthe RSU (Road Side Unit). In this respect Low Profile multiband Antennas for mobile communications using Electomagnetic Band Gap (EBG) structureswere also exploited, since using EBG structures it is possible to designantennas with low profile and simultaneously increase the bandwidth gainand improve the radiation pattern. Other Antennas and related work Other lines of research have been pursued including: •

The design of broadband integrated lens antennas for reflector antenna illumination with constant aperture efficiency across a 1:3 frequency band suitable for quasi-optical radio telescope systems;

•

The design of a dielectric loaded UWB monopole antenna suitable for integration in a USB device;

•

The development of a demonstrator for a recently developed mechanically steerable beam antenna based on a pivoting dielectric lens for 60 GHz wireless communications and realization of preliminary tests with real video transmission.

4.1.3.3 Integrated circuits and systems SI based MMICs The following circuits where fabricated and testedat microwave frequencies (2 and 5GHz) with CMOS 0.18μm technology: low noise converter for 2 and 5GHz, a class D balanced power amplifier (1.45 GHz) and its modulated power supply (100MHz Buck converter). Due to the inefficiency of commercials baluns used on chip-on-board testing of the power

amplifier,

new

are

being

developed.

Based

on

the

measurements of the low-noise converter an improved and complete dual band receiver was designed. From the test of the Buck converter a redesigned was 37

performed. The work included redesign of analogue blocks, such as operational amplifiers and comparators, and new design strategies to reduce bonding inductive paths, either for QFN packages or Chip-on-Board was studied. Preliminary conclusions indicate a performance improvement but simple PWM control technique bandwidth was found limiting for the application in scope. Accordingly, new control strategies are under investigation to increase the control circuit bandwidth. An improved version of the class D power amplifier with envelope detectors and its power supply are being designed and will be fabricated in the first half of 2011. After a simulation study of class E power amplifier, also for 2.45 GHz (MSc thesis concluded in 2010) using both 0.18μm and 0.13μm a prototype will be fabricated in the same run as the class D Power amplifier (0.18μm). From an EM study of monolithic transformers (MSc thesis concluded in 2010) we have concluded that alternative solutions must be studied, mainly for the output power stage. Presently, coupled lines and LC-CL combiners are being studied. At millimetre-wave band lower edge (30GHz), the following circuits were tested: a down-converter and active inductors implemented in 0.25μm SiGe. Based on the test results and reverse simulations a new simple and improved version of the active inductors, with fewer transistors and independent voltage control of inductance and quality factor was designed and will be fabricated in the first half of 2011. At the same frequency band but with a 0.13μm CMOS technology a Voltage Controlled

Oscillator(32.2

using

radio-frequency

capacitors arrays and differentially tuned anti parallel varactors and a Low Noise Amplifier were designed and tapped out for fabrication. They will be tested in the first quarter of 2010. The study of spiral inductors in Silicon technologies (CMOS and SiGe) continue to be performed from 1 to 45GHz. Prototypes where tested and compared with EM simulation with both CMOS and SiGe technologies. To improve the models

accuracy, a study of the technology parameters, some of them not supplied by the foundries, and optimization of the geometrical definition of the inductors on the EM simulators input code is being pursued. Short range communication systems •

A new dual RSE-DSRC (Dedicated Short Range Communication) system was develloped, for automatic identification and toll purposes, in the 5,8GHz band, according to European standards for the physical link and application layers (EN12834, EN12795, EN12253 and EN13372) and compatible with the actual Via Verde System. Design, fabrication and test of a DSRC system prototype were achieved.

Management DSRC 5,9GHz project (IT-Brisa). The main goal of this project

was

the

“Development

on

communications system for road applications, with emphasis on safety, following the WAVE recommendation”. While the standard IEEE-802.11.p is not completed, the development will follow the IEEE 802.11.a whenever necessary. Following the current 802.11p recommendations, basic functionalities will be implemented in order to comply with the identified applications and scenarios. Software defined radio Work was carried mainly on nonlinear distortion and Volterra series forsub-sampling receivers. Moreover the group has devoted a certain amount oftime working on a new vision for improved software defined radiotransceivers, in that sense several FPGA's approaches for a all digitaltransmitter and improved dynamic range has been also a key point of work. Photovoltaic devices Work has been developed for FDTDsimulation of light propagation inside a-Si:H structures. Understanding of light transmission, reflection and propagation inside semiconductor structures is crucial for development of photovoltaic devices. Using FDTD

withwavelengths in the range of the visible spectrum within a a-Si:H p-i-nstructure. While the effects of surface reflections are easily taken into account by the

39

ANNUAL REPORT 2010 – WIRELESS COMMUNICATIONS

algorithm, light absorption represents a more criticalpoint, because of its non-linear dependence from conductivity.

4.1.3.4 Waves and Propagation Work in this sub-area included the characterization of propagation through vegetation as well as research on electromagnetics of complex media with possible applications to antennas and guided wave structures. Studies on EM exposure assessment have also been pursued. Radiowave propagation in vegetation media The RMOM group has been working very actively in the study of the effects of vegetation in radiowave propagation. New mathematical models to characterize the effects of radiowave propagation in inhomogeneous forests at microwaves and millimeter-waves have been devised. In addition, this research was extended to investigate current approaches and develop new more accurate narrow and wideband

channel

models,

and

fast

fading

models

to

characterize

signal

propagating through, around or scattered from vegetation under the effect of wind, resorting both to theoretical investigations and experimental data gathering at 40 GHz. Some of the 2010 contributions of the RMOM group in this topic include: •

Development of a versatile radio channel sounder prototype with the capability

of

characterising

doubly

selective

channels

through

measurements of key channel indicators, e.g. Doppler spectra, channel impulse response and coherence time, at 18 and 38 GHz. •

Development and implementation of a time varying dRET simulator.

•

Enhanced formulation, test and validation of the dRET model using deconvolution techniques to optimise its input parameter extraction method.

• Development of an automatic antenna alignment system based on pan and tilt positioners and inertial navigation techniques.

Development of a fleet management system to remotely acquire data from digital tachographs.

Earth-Satellite propagation On the framework of Earth-Satellite propagation a beacon receiver wasoperated successfully logging one additional year to the propagationdatabase. The database now comprises 6 years. A beacon receiver based onGNU-Radio was developed and results published in a conference paper. Theexperimental database was studied concerning aspects of the parameters attenuation, depolarization and rain rate. The hourly, monthly, seasonallyand yearly variability was and his being studied. The long distance rainand attenuation correlation that is very important for diversity wasstudied in a collaboration framework with Madrid (UPM) giving a paper in ajournal and presentation at COST IC-0802. In the framework of the COST-IC0802 some preliminary study of abovevariability was made by comparing data from Madrid (UPM) and Otawa-Canada(CRL). Propagation channel for mobile communications In the framework of the propagation channel for mobilecommunications the Sage algorithm

Algorithms forclustering techniques were implemented and critically compared in real andsynthetic channel environments. Electromagnetics of Complex Media In the last year work has been done on homogenization and characterization of structured structures. Characterization of novel nonlocal metamaterials, with anomalous

properties,

such

as

or

ANNUAL REPORT 2010 – WIRELESS COMMUNICATIONS

bands has been achieved and demonstration of their use for superlenses has been performed. A more detailed description follows: •

Homogenization and applications of metamaterials with anomalous dispersion. One of the key challenges in metamaterial theory is to reduce the inherent complexity of the microstructure to a few effective parameters, usually an equivalent permittivity and permeability, making an otherwise very intricate problem easily accessible to theoretical modelling. Such an approach is physically sound when the wavelength of the radiation is much longer than the characteristic features of the metamaterial, so that the intrinsic granularity of the system can be neglected, and the structure can be regarded as a continuous effective medium. The homogenization approach is especially tricky in case of spatially dispersive materials, such that the macroscopic polarization does not respond locally to the electric field. One of the contributions of the RMOM group was the development of the theory of spatially dispersive metamaterials based on arrays of nanowires. In particular, we have investigated the electrodynamics of novel nonlocal metamaterials with low loss broadband anomalous dispersion. We demonstrated that such materials can be useful to correct the chromatic aberrations of optical systems, compensating for the normal dispersion of dielectrics.

•

Casimir interaction in metamaterials. The illusive Casimir effect is one of the most intriguing physical phenomena, which, due to the quantum fluctuations of the electromagnetic field, results in the attraction or repulsion of uncharged bodies. This tiny force is only relevant in the nanoscale, since it invariably decays with the fourth power of the distance between the bodies. However, in 2010 the RMOM group has shown how by guiding the quantum fluctuations of the electromagnetic field with an array of metallic nanorods it is possible to boost the strength

of

the

Casimir

force

by

several

orders

of

magnitude.

Furthermore, it was demonstrated how this ultra-long range force can be put into work and used to levitate objects! It is envisioned that these

42

ANNUAL REPORT 2010 – WIRELESS COMMUNICATIONS

findings may have interesting applications in the realization of novel materials with improved adhesive properties (a “quantum”-super-glue). •

Detection of targets separated by subwavelength distances based on a metamaterial with extreme parameters operated in a backscattering mode. One of the holy grails in the metamaterial field has been since the beginning the possibility of imaging not limited by diffraction. This is a quite challenging problem, and a successful approach to superlensing has to overcome many barriers. In 2010, the RMOM group has proposed and demonstrated

experimentally

a

novel

broadband

approach

to

superlensing based on a metamaterial with extreme parameters. It was shown that this novel solution enables discriminating objects separated by tiny distances on the scale of the wavelength. It is expected that such results may have applications in sensing and RFID. •

Development and demonstration of a novel minimally invasive system based on a metamaterial lens to measure the near-field of an antenna. Measuring the near-field has important applications, such as the calculation of the radiation pattern of large aperture antennas. However, the

realization

of

near-field

probes

for

all

components

of

the

electromagnetic field may be quite challenging, particularly if one is interested in measuring both amplitude and phase. Moreover, the measurement of different components of the field typically may involve the use of different probes, which may interact with the antenna under study in the different manner, resulting in the inaccurate determination of the near-field. In 2010 the RMOM group proposed and demonstrated experimentally a metamaterial inspired near-field lens that enables the characterization of the near-field field of an antenna in a minimally invasive manner. •

Ultrasubwavelengthwaveguiding. Confining and guiding electromagnetic radiation in volumes with dimensions far beyond the diffraction limit can have important applications in emerging nanotechnologies. A popular approach

to

subwavelengthwaveguiding

is

based

on

43

ANNUAL REPORT 2010 – WIRELESS COMMUNICATIONS

plasmonpolaritons (SPPs) supported by metal-dielectric interfaces. This is viable at optical frequencies where the dielectric constant of metals is predominantly real and negative. At lower frequencies, metals begin resembling perfect electric conductors, leading to weakly bounded SPPs. In 2010 the RMOM group has proposed a solution to this problem, and demonstrated that strongly coupled grids of metallic nanorods, resulting from the hybridization of weakly bounded plasmons, enable wide band low loss ultra-subwavelengthwaveguiding, which may determine a new paradigm for light confinement and waveguiding in the nanoscale. Fundamental work on electromagnetic wave propagation in complex media (namely chiral, anisotropic and bi-anisotropic media) has been continued both for unbounded media and in the presence of interfaces (reflection and transmission characteristics). Applications of the Clifford (geometric) algebra of the (ordinary) three-dimensional space to the analysis of anisotropic media characterized by both electric and magnetic anisotropic functions as well as applications of spacetime algebra, the Clifford algebra of Minkowskispacetime, to relativistic optics of moving media have been studied. The main results of this work include: •

A new classification scheme for anisotropic media based on the overall behavior of the medium, rather than on the permittivity and permeability functions separately considered;

•

A new perspective on moving media, that simplifies and brings new physical

and

geometrical

insight

as

compared

to

the

traditional

formulation using tensor and dyadic calculus. Work on guided wave structures with chiral media has been continued and propagation characteristics of chiral H-guides have been studied. A new line of research has been open on indefinite media, i.e., media with simultaneous positive and negative parameters. Several uncommon properties as coexistence of forward and backward waves and contra directional coupling have been explored.

• The development of channel models for Body Area Networks; • The continuing development of CRRM algorithms for heterogeneous mobile communication systems; • The development of RRM algorithms for virtual communication systems; •

The development of various simulators for the air interface of UMTS-FDD, with HSDPA and HSUPA, and LTE, enabling analysis of traffic aspects as well as load and handover ones.

4.1.3.6 Transmitting and Receiving Systems These studies were mainly concentrated in the optimization and performance of current and next generation radio systems, both for mobile communications (such as Wimax, LTE and LTE-Advanced) and satellite systems, with special emphasis on radio navigations systems. Mobile communications The achievements for mobile communications in 2010 focused on several aspects of present and future radio systems, such as network planning, air interface and capacity enhancements, and channel estimation. Following the work of previous years, studies were performed to coordinate the interference for E-MBMS transmissions in LTE-Advanced systems, figuring out some power saving techniques. Capacity enhancements for wireless communications systems using multiuser MIMO techniques, namely for LTE in macrocell scenarios, were also studied. Networking aspects were also addressed, namely radio network planning for the next generation cellular networks, the study of centralized cooperative spectrum sensing for ad-hoc disaster relief networks and also with iterative multipacket 45

detection for high throughput transmissions in OFDM Systems. WIMAX and Wi-Fi networks were also planned and deployed regarding Health Sciences Education and applications such as wearable sensors for foetal movement monitoring in low risk pregnancies. The air interface of radio systems was also studied in several aspects including modulation, coding, equalization, channel estimation and synchronization. Most of these studies were based on an analytical approach. For example, the analytical evaluation of nonlinear effects on OFDMA signals or an analytical approach to evaluate the performance of a class of receivers with joint equalization and carrier frequency synchronization. Other studies focused on nonlinear frequency domain equalization with single carrier modulation. Some studies were closely related to modulation. For example the analytical matched filter bound for M-QAM hierarchical constellations with diversity reception in

multipath

fading

channels

and

an

domain

equalization and carrier synchronization for multi-resolution constellations. Other new research aspects with interesting results include a new analytical model to evaluate the correlation of spreading sequences when submitted to a nonlinear system, using the family of OQPSK signals. This allowed us to determine and compare the properties andbehaviour of different types of sequences (such as Gold, maximal length and TCH) when submitted to a real nonlinear system. Using this approach, new results and studies can now be obtained to improve important aspects of receivers such a synchronization or channel estimation. Satellite systems were also a subject of research in many aspects. A new technique based on Magnitude Modulation has been devised to reduce the back-off in satellite transmissions using digital signal processing techniques to implement polyphase filtering nagnitude modulation. This technique can now be used for QAM modulations to efficiently reduce the power requirements in this type of systems. The existing satellite earth station at the Instituto de Telecomunicações was also improved with the implementation of a dedicated server for remote operation and control.

ADCOD Advanced Code and Receiver Designs for Transmission over Selective Radio C

Funding

FCT/PTDC

Descript.

Future wireless systems are expected to support data rates of several hundreds of Mbit/s in a variety of scenarios with high spectral and power efficiencies. Due to high transmission rates the channel will be severely

time

dispersive.

For

this

reason,

block

transmission

techniques combined with frequency-domain equalization (such as, OFDM (Orthogonal Frequency Division Multiplexing) and SC-FDE (Single-Carrier Frequency-Domain Equalization) modulations schemes are strongly recommendable. A key technology to improve power and spectral efficiencies is the use of multi-antenna schemes exploiting spatial diversity (such as STF (Space-Time-Frequency) codes) and spatial multiplexing (such as LST (Layered Space-Time) techniques). The use of signals with reduced envelope fluctuations is also important to allow efficient power amplification. This is particularly important in the case of OFDM signals. Conventional FDE implementations require accurate channel estimates at the receiver, something particularly important in multiantennas systems. These estimates can be obtained with the help of appropriate training symbols or blocks. Due to frequency offsets and Doppler effects, the channel is expected to change from block to block, or even within a given block, especially for large blocks, high carrier frequencies and/or high moving speeds. In this case, it might be recommendable to employ non-coherent systems. This project considers

efficient

transmission

schemes

for

frequency-selective

channels. For this reason, we will employ OFDM and SC-FDE block transmission formats with multi-antenna schemes. The research team involved in this project includes researchers working in transmission, 49

ANNUAL REPORT 2010 – WIRELESS COMMUNICATIONS

codebook and receiver design and optimization, as well as researchers working on propagation issues. In the first phase of this project, we address the problem of STF codebook design for both coherent and non-coherent

communications.

In

contrast

with

conventional

approaches, the codebook design takes into account the envelope fluctuations and dynamic range of the transmitted signals, so as to allow efficient power amplification. We will also take into account nonlinear effects (e.g., due to clipping of OFDM signals) in the STF code design. The impact of nonlinear distortion effects on the designed STF codes will be studied, whenever possible, employing analytical methods. Contrarily to the usual approach, we will take into account non-white noise effects (e.g., due to self-distortion inherent to nonlinear effects) in our designs. Pragmatic code designs (eventually combined with conventional error correction schemes and allowing low-complexity transmitter/receiver implementations) will also be considered. In the second phase of this project, we will generalize the results obtained in the first phase to the fading channels that are both timedispersive and time varying (i.e., doubly selective channels). For the coherent case, the combination of suitable block/frame designs and adequate estimation and tracking techniques (both for the channel frequency response and the frequency offsets/phase noise carrier) will be considered to cope with time-varying channels. We will also develop receiver structures for the case where the channel changes significantly within a given block, both coherent and non-coherent. To achieve these goals, we need accurate channel models taking into account short-term and long-term variations. We will develop new, more

accurate

narrow

and

wideband

channel

models

through

theoretical investigations as well as experimental data gathering for different frequencies (e.g., 2.4, 5.6 and 38 GHz), in several deployment scenarios. A time-varying tapped delay line based model will

be

developed

to

represent

the

doubly

channel

phenomena. The combined channel model will be suitable for simulating fading mitigation techniques such as adaptive coding and

50

modulation, interference cancellation, and other capacity enhancing techniques. We will also consider STF codebook designs and receiver designs exploiting the knowledge about short and long term channel statistics.

C2POWER Cognitive radio and Cooperative strategies for POWER saving in multistandard wireless devices

Funding

EU, FP7

Descript.

The promise of a truly mobile experience is to have the freedom to roam around anywhere and not be bound to a single location. However, the energy required to keep mobile devices connected to the network over extended periods of time quickly dissipates. In fact, the operational time, has been identified as the number one criteria by the majority of the consumers purchasing a mobile device. Moreover, concern about exhausting battery lifetime is also one of the main reasons why users do not opt to use advanced multimedia services on their mobiles more frequently. To avoid the foreseen 4G “energy trap” C2POWER project will 52

Title

Cooperative and Antenna Diversity for Broadband Wireless Networks

Funding

FCT/PTDC

Descript.

Wireless services are of great economic and social value and will be one of the enablers of the so-called information society. It is envisioned that among the multiple networks/services that will be part of what is commonly termed as 4G, we will have a broadband component, where spectrum

efficiency

will

be

a

premium.

This

means

that

the

terminals/access points will need to explore in a “quasi-optimal” way all the dimensions provided by the space/time and frequency domains of the radio channels. Diversity is inherent and well known in the physical layer and either time, frequency, space has been used to combat the fading by trying to stabilize the channel. Diversity can also be achieved in the MAC or higher layer, which is termed network diversity, which can be divided in multiuser diversity (by scheduling or routing) and cooperative diversity (by cooperative transmission). While research concerning the classical forms of diversity has already taken a very practical flavour with proposals/technological evaluation and integration,

53

the know-how to exploit the benefits brought by the cooperative dimension is still far behind and also the understanding of the impact it may have on wireless network planning. These provided the main impetus

for

this

project

proposal

whose

key

objectives

are:

Definition, evaluation and validation of techniques exploiting channels diversity and cooperation between users in order to enable the high bit rates targeted in the broadband component of future wireless systems; improve the power and spectrum efficiencies of the existing OFDMbased wireless systems and improving and/or extending coverage and fairness. Most of the research work in this area have assumed dedicated relays (fixed or nomadic), while the CADWIN project will also consider relaying functionalities at the MT. To reach these main goals, specific research objectives are: • Design and evaluation of practical VMIMO or distributed coding algorithms. In a first phase we will start with space-time/frequency block codes designed for co-located antennas, which will be evaluated in a distributed environment. In a second phase, specific and optimized solutions will be proposed and investigated. • Design and evaluation of practical distributed precoding algorithms considering different levels of the channel state information available at the transmitter (BS in the downlink), relay and destination (MT in the Downlink). Precoding algorithms to enable cooperation between base stations to provide intercell interference cancellation will also be considered. • Design and evaluation of joint distributed precoding and spacefrequency/time coding algorithms. In a first phase the concepts of distributed precoding and coding are considered separately, while in a second phase the researchers working on the two topics will consider the optimized joint precoding/coding schemes. • Design and evaluation of channel estimation algorithms. In a first phase we will evaluate the classical channel estimation algorithms in cooperative communications scenario with emphasis on AF relaying protocol. In a second phase, will investigate and evaluate specific algorithms to deal with the issue of estimating non point-to-point

COGEU Cognitive radio systems for efficient sharing of TV white spaces in EUropean context

Funding

EU, FP7

Descript.

The complete transition from analogue to the digital TV is planned in Europe for 2012. This will release significant amount of valuable spectrum in VHF/UHF bands. In fact, the Digital TV Switchover provides a “once in a lifetime” opportunity for the development of innovative services and the introduction sophisticated new technologies into the VHF/UHF bands. However, despite the grand words about opening up a new band to support low cost, low power, ubiquitous access and innovative new providers, there are many obstacles to TV white spaces systems. The creation of workable devices that clearly demonstrate and prove that no harmful interference is caused to broadcasters or other licensed systems is one of those challenges as is the completion of standards. The CogEU project aims to take advantage of the transition to digital TV by developing cognitive radio systems that leverage the favourable propagation characteristics of the TVWS through the introduction and 55

promotion of real-time secondary spectrum trading and the creation of new spectrum commons in the upper band of the cleared spectrum. CogEU will also define new methodologies for TVWS equipment certification and compliance addressing coexistence with the DVB-T/H European standard. Three main application scenarios with good market potential will be investigated: •

Cellular, WiFi and WiMax network extension over TV white spaces

•

FCT/PTDC

Descript.

The aim of the project is to provide a better understanding of multiuser coordinated

multiple-input-multiple-output

(MIMO)

capacity

enhancement in the fourth (and future) generation(s) of wireless systems. In fact, the realistic capacity estimation using spatial multiplexing and beamforming MIMO is of great interest, since it represents the enabling technology to achieve the new 4G 5 bit/s/Hz spectral efficiency requirement. MIMO links can offer a so called spatial multiplexing gain by opening parallel spatial data pipes or channels within the same frequency band. This is achieved by the creation of orthogonal information channels mostly

in

the

presence

of

rich

to

decorrelation. In these conditions, MIMO links offer capacity gains (relatively to SISO) that are proportional to the minimum of either the number of TX and RX antennas. As a matter of fact, a key feature of MIMO is to turn multipath propagation, traditionally a pitfall of wireless systems into a benefit for the user. MIMO takes advantage of random fading, for 56

increasing transfer rates. The proposed work in the project will cross the fields of research of mobility and channel modeling, information theory and practical systems and applications. Firstly, directional channel modeling will be developed in order to simulate the MIMO channel. Secondly, information theory and eigenanalysis based on MIMO spatial multiplexing and beamforming will be used, together with the use of uniform and power efficient allocation methods. Optimized MIMO antenna configurations will be set, in order to boost up cell capacity. Then, the gains of using coordination methods in multiuser scenarios will be considered with applications examples and system performance evaluations over LTE (and LTE Advanced) and mobile WiMAX 802.16 family of standards radio interfaces. This evaluation will be done considering radio advanced resource management techniques such as improved admission control, power control and scheduling techniques.

Multi-Packet Detection Techniques for Satellite Networks

FCT/PTDC 63

ANNUAL REPORT 2010 – WIRELESS COMMUNICATIONS

Descript.

Future satellite communications systems face a challenge to provide higher bitrates, together with improved QoS (quality of service) guarantees, to more GT (ground terminals). Moreover, this should be achieved with higher spectral and power efficiencies, with less energy. This project considers future very high bitrate LEO (Low Earth Orbit) satellite systems with satellite MPR (multipacket reception), compatible with low-cost portable GTs. A cross-layered approach is proposed: a physical layer team will handle the signal design, the synchronization and

estimation

issues,

and

the

receiver

design,

including

MPR

development; a data link layer team will handle the Multiple Access control protocol design and the scheduling algorithm to support different QoS (Quality of Service) classes, and the interaction with the network layers. Both teams will be involved in the design and test of the cross-layering features involving both layers, required to provide guaranteed QoS, even during satellite handover. In this project we will develop OQPSK-type schemes with reduced envelope fluctuations and high power and spectral efficiencies and compatible with an efficient and low cost power amplification. To further improve the overall system power efficiency we also consider schemes

with

spectral

overlapping

between

different

frequency

channels. With respect to the receiver design, the main goal is an efficient multipacket detection technique able to cope with collisions, already shown by the research team to allow significant improvements in personal area networks. We will consider turbo frequency-domain equalizers suitable to cope with time-dispersion effects and able to handle spectral overlapping between frequency channels. Hybrid ARQ/FEC (Automatic Repeat reQuest/Forward Error Correction), namely with packet combining, will be proposed to handle fading for the most demanding QoS classes and control packets. To cope with Doppler effects, suitable synchronization and channel estimation methods will be developed for MPR on a LEO scenario. Joint detection and estimation schemes will be considered. Since MPR needs to know which users are involved in a collision, suitable methods to detect them will be developed. The statistical characterization of block error rates with MPR 64

ANNUAL REPORT 2010 – WIRELESS COMMUNICATIONS

will be evaluated using simulations for homogenous and heterogeneous SNR GTs. We will develop a new MAC protocols for MPR that combine random access with demand assigned access on the uplink controlled by a downlink control channel, offering improved QoS support compared to other LEO MAC protocols.

Networks of the future are tending towards a diverse wireless networking world, where scenarios define that the end-user will be able to attain any service, at any time on effectively any network that is optimized for the application at hand resulting in “flexibility and choice” to enhance the quality of life of the individual, in a context of seamless interoperability and cognitive radio between network operators and access technologies, complemented by a business exploitation strategy that adapts to future economic infrastructures. Advanced algorithms for multi-band access/selection will be explored to optimize the offered capacity whilst maintaining the user service experience acceptable. Also secondary users may have temporary opportunistic access to free spectrum ''holes'' or a set of users may simultaneously utilize, optionally, spectrum resources in lower/upper frequency

bands,

The

consequences of this new perspective for spectrum management in public policies will be addressed as well as the impact of having secondary spectrum markets. From the technical point of view, modeling, simulation and experimental approaches will be followed, e.g., by using emulators with a hardware component within academic and/or industrial partnerships to be developed. Spectrum usage optimization is one of the goals of our Project, fig. in Annex. The opportunistic utilization of spectrum holes by secondary users will be investigated by implementing novel MAC designs regarding sensing cooperation and opportunistic transmission that will use cross layer and cross system information. Another objective is to attend to the increasing demand of higher data rates. Spectrum aggregation (SA) is a technique that attempts to increase spectrum utilization and it is therefore a coming solution to support the 100 MB/S over a wireless connection.

The MB-CRRM has the ability to optimize frequency scheduling for infrastructural users, and also frequency scheduling for secondary usage. While each system maintains control over his RRM entity, including the distributed secondary system, the MB-CRRM entity will make them more dynamic radio wise. A wide and local MB-CRRM optimization could be differentiated. By wide MB-CRRM it is meant frequency planning for all the systems being considered in a given area considering several base stations (BSs).

of

an

innovative RF Self-Oscillating Power Amplifier (SOPA) in which the feedback loop is not made at the RF carrier, as in the usual approach, but now between the output signal envelope and the input baseband signal. This topology is a novel, and very promising, approach to the linearity/efficiency compromise in RF transmitters as it is capable of greatly

but

also

for

the

nonlinearities of the AM and PM modulator, of the RF PA and of the output band-pass reconstruction filter. Furthermore, the complex stability and ultimate injection locked behavior analysis of these SOPA structures (which is a determinant problem for any highly nonlinear dynamic

amplitude.

In addition, this new SOPA based Tx architecture, but also many other coming digital Tx’s, suffer from the inexistence of proper simulation tools. As they involve baseband AM and PM signals, a digital selfoscillating clock and a RF carrier - of three disparate time-scales exciting strongly nonlinear low-frequency broadband but also RF narrow-band circuits, no circuit simulation tool is able to handle it. So state-of-the-art simulation techniques for systems with autonomous components

(as

is

the

case

of

SOPAs)

will

be

studied.

In summary, the expected results from this project are: (i) systemlevel analysis of SOPA behavior, its stability and injection locking conditions; (ii) the design, implementation, test and validation of a novel, highly efficient and linear, SOPA based Tx topology; and (iii) a

Descript.

Software Defined Radio has already start its way to conquer traditional radio

configurations,

by

(de)modulators

completely to the digital world and thus implementing it by software. Nevertheless, it is expected that Cognitive Radio, CR, will be the next frontier in terms of radio architecture design, in fact the new paradigm that CR can bring to traditional ways to think on radio architectures, is so huge, as it was the transition from Analog to Digital systems. CR will allow the optimization of radio spectra occupancy, but also the implementation

of

the

supreme

universal

radio,

that

is

radios

that talk to each other’s no matter the original implementation. But in order to achieve such a new deployment, the radio should be constructed with some form of processing capabilities, which it is not possible with traditional schemes, that processing capabilities arises from some kind of processor that treats the transmitted/received signal in real time, and makes decisions over it. That

processing

capabilities

should

be

done

at

the

digital

counterpart, but also, and most of the time neglected, at the analog part. In fact the main conclusion of the last SDR forum meeting was that the analog part, usually called agile radios, should have a huge

research

effort

in

order

to

implement

most

of

the

CR

concepts. This project aims exactly to study most of the physical layers of CR, starting from agile RF front ends, but also considering digital implementations,

either

FPGA

based,

but

also

DSP 75

based.

ANNUAL REPORT 2010 – WIRELESS COMMUNICATIONS

The project will try to give an answer to software engineers, by carefully studying the last piece of the system that is avoiding the complete implementation of CR. The main difficulty of implementing these CR architectures is the non-ideal behavior of the analog components, due mainly to bandwidth limitations, and to signal amplitude limitations, dynamic range, by creating nonlinear distortion that severely degrades SNR. Thus the correct identification of the system components behavior, that is nonlinear dynamic models, the correct understanding of the new waveform behaviors, which will be created in the CR approaches, will allow the correct design of the transmitted signal. This signal should be pre-distorted in order to be transmitted with perfect spectrum masks, but the received signal should also be compensated either by overcoming the non-idealities of the receiver components but also by reducing interference distortion due to the existence of jammers outside the band. Thus the now proposed work will make new contributions on (1) behavior models for non-ideal analog RF components; (2) new signal identification methods, either for evaluation of the analog needs at transmission or at receivers, but also for spectrum sensing; (3) new waveform generation for CR applications, in order to maximize the SNR, but also for maximize the transmitted bit rate; (4) new design of reconfigurable architectures based on FPGA, for efficient CR implementation; (5) improved receivers for spectrum sensing sub-systems by maximizing the gathering of large bandwidths; (6) new improved receivers for maximization of dynamic range; and finally (7) new transmitters for linear and high efficient signal communications.

4.2.3.2 Optical Components and Subsystems The work carried out in this sub-area concentrated on the modeling, performance evaluation, optimization and implementation of key components and subsystems for all-optical networks. The transfer matrix method (TMM) has been extended for the dynamic analysis of non-conventional DFB laser structures (dynamic TMM). The transient response (emitted power) and the variation of the lasing wavelength with time for MPS-DFB structures, when the biasing current (modulation depths) is a step-function, have been analysed. The study of frequency response of semiconductor PIN photodiodes for optical communications continued. The numerical model for the frequency response was generalized by including the capacitive effects which are known to play an important role in the frequency response of short devices. A detailed analysis of the effect of the length of the absorption region, the area and series resistance of the device and the bias voltage on the bandwidth was undertaken. In order to overcome the limitations imposed by the capacitive effects to the bandwidth of the device, some novel structures were investigated namely of the type PIIN where the added intrinsic region is of the same semiconductor material as the N and P regions. Some preliminary results show that these optimized structures have larger bandwidths than the conventional PIN structure. An analytical model accurately describing the evolution of the relative state of polarization between two signals in high-birefringence fibers was developed. It was shown that for small fiber lengths or narrow wavelength separation, launching two signals with orthogonal polarizations can present a higher degree of co-polarization along the propagation. The model was experimentally validated by comparing 118

ANNUAL REPORT 2010 – OPTICAL COMMUNICATIONS

theoretical and experimental four-wave mixing results in a dispersion shifted highbirefringence fiber. The influence of the stimulated Raman scattering in the four-wave mixing process in high birefringent fibers was theoretically analyzed. Results show that when the phase-matching condition is satisfied the optical power evolution of the signal and idler waves for small frequency detuning are mostly described by the anisotropic Raman response of the fiber, whereas for high frequency detuning the isotropic response dominates. Our analysis also shows that the stimulated Raman scattering can increase the efficiency of the four-wave mixing process, for certain frequency detuning. A new method to measure the effective nonlinear parameter of a fiber was developed. The effective nonlinear parameter was experimentally measured and the transition region between an almost co-polarized to a de-correlated state of polarization was observed. The method was experimentally validated by comparing theoretical and experimental four-wave mixing results in a low power regime. In the area of optical amplification, a new method to mitigate the transient effect in optical fiber Raman amplifiers was developed. This method is based on a pumpcontrolled gain-locked system and is suitable to be used in pump-reflecting Raman fiber amplifiers. Using this approach, an efficient low-cost Raman fiber amplifier suitable for dynamic optical networks was obtained. The developed method was subject to a patent registry. Optical amplification in the visible spectral region for plastic optical fiber applications

was

also

studied

theoretically

and

experimentally.

Reflective

semiconductor optical amplifiers have been characterized under RF modulation, in order to optimize its parameters for radio over fiber applications. Work has also been carried out in the area of production and characterization of components in integrated optics. Mach-Zehnder and Y-branch splitter, based on sol-gel technologies, have been developed for passive optical networks. In the area of all optical processing for high bit rate optical networks, advanced techniques for all-optical routing, tunable dispersion compensation, optical filtering, pulse shaping, clock recovery, optical code division multiplexing and regeneration were developed.

119

ANNUAL REPORT 2010 – OPTICAL COMMUNICATIONS

An acoustic wave generator for optical fibers to be used in tunable filters was designed and implemented. Research work on all optical signal processing with semiconductor optical amplifiers started, and a lab experiment has been designed for evaluating new applications, namely static RAM. Work in the area of optical sensors included: the development and optimization of a fiber monitoring system, based on fiber sensors and wireless transmission; novel plastic fiber sensors for refractive index and bending measurement; a novel sensor for simultaneous refractive index, temperature and stress measurement based on a tilted fiber Bragg grating; and a novel sensor for simultaneous measurement of temperature and deformation based on a tapered fiber. These sensors were tested in civil engineering infrastructures as metallic bridges, metallic telecommunication towers and concrete structures The work on all optical signal processing with SOAs has been focused on the set-up of a lab experiment for evaluation of static RAM. A new proposal for implementation of static RAM has been presented.

4.2.3.3 Optical Communication Systems Advanced modulation formats for optical fiber communication systems were investigated. A novel semi-analytical method for BER evaluation in simulated optical DQPSK systems was developed, and an accurate method of performance assessment for DQPSK systems in presence of receiver imperfections was proposed. Pseudo-linear transmission regime with high-speed optical singlesideband (OSSB) signals and electrical dispersion compensation was investigated. An analytical method to estimate the degradation of signal quality in case of OSSB signals with different modulation formats was investigated. In the area of radio over fiber (RoF) systems, optical filters were developed and optimized for these systems. Performance of BPSK vs QPSK for optical distribution of orthogonal frequency division multiplexing (OFDM) ultra-wideband (UWB) radio signals in fiber-to-the-home (FTTH) networks was compared. The state-of-the-art of joint optical/radio OFDM transmission impairment compensation was identified. Research on 60 GHz MMW band focused on photonic techniques for generation of MMW sub-carriers has begun during this reporting period. Transmission of 802.11g signals over a 10Km RoF link was demonstrated. 120

ANNUAL REPORT 2010 – OPTICAL COMMUNICATIONS

The Ph-ADC photonic structure based on TDM was optimized and the impact of nonlinear fibre impairments on the Ph-ADC performance was assessed. The feasibility of the structure for photonic analog-to-digital conversion (Ph-ADC) based on wavelength division multiplexing was investigated in the UCELLS project. Its performance was compared with the performance of the Ph-ADC photonic structure based on TDM. Numerical and experimental investigation concerning the transmission of multiband OFDM-UWB radio signals along distances typical of next generation fibre-tothe-home (NG-FTTH) networks, using directly modulated lasers (DML) and externally modulated (EM) transmitters has been performed. The investigation of optical-wireless convergence in NG-FTTH networks was started. Preliminary numerical and experimental work concerning the transmission of coexisting OFDM signals using DML and EM as optical transmitter has been performed. Research work on the linearization of direct-modulated lasers for application in the transmission of different wireless standardized signals through optical fiber has been initiated. Optical transmission systems based on mode group diversity have been identified as having a large potential. A digital simulator of the propagation in multimode fibers is under development which takes into account modal coupling at fiber imperfections and splices between monomode and multimode fibers. A nonlinear model for pulse propagation in multimode fibers with reduced radius, which support a small number of modes, is also under development. The transmission of multiband orthogonal frequency division multiplexing (OFDM) ultra-wideband (UWB) radio signals along multimode fibre was investigated. The main transmission impairments were identified. Research on RoF systems in the framework of project RoFnet (FCT) has been directed to the MW and MMW bands, and was focused on photonic techniques for generation of MW and MMW sub-carriers. New proposals for simultaneous transport of different services in the baseband and in several microwave and millimeter wave bands, and about the optimum operating conditions for supporting multiple radio channels over a SCM-based distributed antenna system. A rigorous method (based on the moment generating function) to assess the performance of the transmission of OFDM signals with direct-detection optically preamplified receivers has been started. 121

ANNUAL REPORT 2010 – OPTICAL COMMUNICATIONS

4.2.3.4 Optical Networking The work on access networks has continued, focused on next generation PONs and their convergence/integration with MANs. In the area of FTTH, there have been some main achievements which some resulted in 2 national patents and one international patent in the field of OTDR for PON

and

remote

powering

of

amplifiers.

This

aligns

with

several

other

achievements in the design of other specific blocks for NGPONs, like amplification schemes to extend the GPON operation range. These amplification schemes were implemented using EDFA, SOAs and Raman amplifiers with the appropriate transients mitigation schemes. The search for new CDMA codes has been pursued, by exploring their applicability in access networks with coherent modulation and detection. Work on optical burst-switched networks continued in 2010. A framework for routing path optimization by using an ant colony optimization technique was developed and its performance was evaluated by network simulation. A strategy for optimizing the structure of an OBS burst-switch by using wavelength contention minimization algorithms was proposed. The use of Raman amplification in optical burst switched networks was analyzed and compared (experimentally and by simulation) with other amplification technologies (EDFAs and SOA). Work on optical burst-switched networks continued in 2010. Strategies to deal with quality-of-service differentiation in OBS networks have been developed. In the packet networks area, an all-optical packet monitoring technique was derived and is being simulated and started its path to experimental demonstration in order to give to the physical layer some more abilities and capabilities. In the all-optical processing, some efforts we have been made in deriving some latching structures and with that aiming the all-optical memories. A set of schemes were observed and proposed. An optimization framework for designing OTNs in environments with mixed line rate demands (40 Gb/s e 100 Gb/s), aiming the minimization of the network cost, by taking

into

account

aspects

such

as

grooming,

virtual

concatenation

and

regenerator placement has been proposed.

122

ANNUAL REPORT 2010 – OPTICAL COMMUNICATIONS

A planning tool to design multi-stage passive optical networks, which includes the proposal of an ILP (Integer Linear Programming) model and an efficient heuristic to deal with the optimization problem, has been developed. Investigation on physical layer impairments was pursued. An analytical treatment appropriate to compute the performance of DPSK receivers in the presence of inband coherent crosstalk originated inside the optical nodes was developed. Implementation of PON scenarios with power over fiber to the electric powered of remote nodes. The viability of this solution was studied theoretically and demonstrated with a laboratorial implementation, being possible to achieve an average power transmission over 20 mW along 20 km of fiber. In the areas of high power in optical networks, guidelines for the transmission of high power optical signals in fiber systems were derived, and the constraints resulting from the fiber heating and development of strategies to the mitigation of the fiber fuse effect were studied. These studies were extended to analyses of optical fiber rehabilitee under extreme conditions, such as high power propagation and fiber degradation due to extreme climatic conditions.

The goal is to increase knowledge about the basic mechanisms of the interaction of light with matter on a subwavelength scale. The scientific innovation concerns: the basic mechanisms of light-matter interaction in micro- and nanostructured materials - including metals (plasmonics), the trade-off between strong localization and propagation losses, photonic diagnostic instruments, and non-linear effects. The technological impact of the Action will lead to the implementation of advanced optical equipment and devices with high performance and low cost. The scientific 128

Descript.

We will fabricate and characterize highly nonlinear fibers obtained by tapering standard optical fibers. Highly nonlinear fibers will be used to produce a super-continuum and to implement two all-optical signal processing devices: i) an all-optical signal regenerator for intensity modulated signals based on self-phase modulation (SPM) and ii) an all-optical signal processing regenerator for nonlinear phase noise reduction based on four-wave mixing (FWM) suitable to be used in phase modulated signals. An accurate numerical modelling and the design optimization of both tapered fibers (TFs) and microstrutured fibers (MFs) will be realized, in the perspective of their use to generate a wide and flat super-continnum, as well as some nonlinearity-based optical signal processing functions, namely the

Transmission of UltRa wide-Band radio signals over Optical fibre

Funding

FCT/PTDC

Descript.

This project proposes to investigate the performance impairments of the orthogonal frequency division multiplexing ultra wideband (OFDM-UWB) radio signal transmission in fiber-to-the-home (FTTH) networks and optimize the system parameters through analytical and numerical simulation work, and to experimentally demonstrate the

main

results

obtained.

Particularly,

the

study

and

the

assessment of the main system impairments is performed, such as: (i) electrical crosstalk associated with multi-channel OFDM-UWB transmission, (ii) linear and non-linear fibre effects, (iii) optical crosstalk associated with the transmission of several optical channels using dense wavelength division multiplexing (DWDM). Different techniques to reduce the performance degradation caused by such limitations

are

also

investigated.

The work to carry out along this project targets the transmission of OFDM-UWB

radio

signals

in

FTTH

networks

using

external

modulation (EM) and direct modulation (DM) of the emitter laser. The transmission of OFDM-UWB radio signals over multi-mode fibre is also a topic to be investigated in the project, since this type of fibre is used in the user’s premises due to its easy maintenance and utilization.

4.3.3.2 Processing, Analysis and Coding of Audio and Visual Information Distributed video coding The main topics addressed were: •

Definition of efficient encoder rate control solutions for transform domain DVC, thus avoiding a feedback channel to perform efficient rate control.

•

Proposal of an iterative side information creation algorithm inspired in video denoising filters and requiring some statistics of the virtual channel between each side information hypothesis and the original data.

Perceptual video coding The work focused on: •

Extension and integration of a perceptual visual model in the High Efficiency

Coding

experimental

codec

to

improve

its

performance. The designed extensions are related to the new Integer Discrete Cosine Transform block sizes as well as the new Mode Dependent Directional Transform. Moreover, an estimation mechanism for the perceptual model at the decoder side is also integrated to avoid the rate burden of sending to the decoder the model parameters. •

perceptually driven coefficients pruning method using the thresholds provided by a selected just noticeable distortion model to set some of the DCT coefficients to zero is integrated; after, an adaptive quantization method adjusting the quantization error based on the same thresholds has been included. •

Proposal of a perceptual optimization of the H.264/AVC deblocking filter offsets based on a quality metric able to quantify the blocking artifacts impact on the perceived video quality. The proposed optimization in made for the HEVC codec and involves low computational complexity and provides quality improvements with respect to a non-perceptually optimized H.264/AVC deblocking filter.

3D Holoscopic Video Coding In 2010, research on video coding and processing techniques for 3D video were initiated, focusing mostly 3D holoscopic video, which is a strong candidate for next generation 3D television. A special attention was given to the estimation of spatial prediction when encoding this type of content. Other Video Coding Topics •

Inpainting-based image codecs, able to improve the image compression efficiency, by building on top of the JPEG image coding standard; its rate-distortion performance was assessed using a novel methodology, particularly suitable for perceptual image codecs.

•

Anovel depth map codec encoding the depth data by means of a binary tree triangular decomposition and reconstructing the depth map values by means of a triangle based planar approximation.

•

New ways of detecting errors for lossy transmission channels in JPEG2000, as well as new algorithms for JPEG2000-based multipledescription video coding.

•

New algorithms for robust peer-to-peer video streaming using multiple description coding.

•

A rate control technique for frame-based video coding systems, such as those based on the H.264/AVC video coding standard, has been developed. 165

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

Quality Evaluation Continuing the work started four years ago, research has been focused on noreference, objective metrics for quality evaluation of video sequences, subject to lossy encoding and transmission errors. Concerning the first issue (lossy encoding), a new quality assessment algorithm for H.264/AVC encoded sequences has been developed and published in IEEE Trans. on CSVT. Some preliminaries studies have also been conducted in order to evaluate the use of simple network based metrics, like the packet loss rate, and of their combination with video bitstream based features, to quantify the perceived loss of quality due to transmission errors. Video Analysis •

Initial steps were taken to address the problem of 3D holoscopic images analysis in view of their segmentation.

•

Work on the objective evaluation of video segmentation quality has been continued, notably focusing on extending the existing metrics to better reflect the temporal aspects of the human visual system.

•

In the field of video object detection and tracking for large public environments, robust and efficient background modelling algorithms have been investigated.

•

Work on the analysis of road pavement images for the automatic detection of cracks and their characterization has been continued. This type of analysis is valuable tool for the supervision and management support of road infrastructures.

Medical Signal and Image Analysis •

In gastroenterology imaging, we focused on emerging modalities, such as Capsule, Narrow-Band Imaging, and High-Definition Endoscopy. Our research addressed how computer vision techniques and tools can be a key factor for developing automated or semi-automated computer assisted decision systems for gastroenterology.

•

Auscultation is both a powerful tool for screening the generic population for cardiac diseases and a hard clinical skill to master. Our motivation was to address state-of-the-art digital audio signal processing research challenges for extracting clinical features from auscultation, as well as 166

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

providing a clinical second opinion on specific heart pathologies. We paid particular attention to aortic pulmonary signal decomposition and its correlation

with

pulmonary

arterial

pressure,

researching

novel

algorithms that can enable us to assist clinicians in the detection of pulmonary arterial hypertension situations. This is a good example of a reasonably common and sometimes deadly pathology that is difficult to detect by inexperienced physicians and which has a good prognosis when detected early. •

We have continued the work in the context of the “Vital Responder” research project (funded by the CMU-Portugal program). Using Vital Jacket® technology, our research team worked on signal processing aspects and human-computer interaction problems.

•

We have exploited the use of computer vision and human-computer interaction techniques as a way to automate the image capture and analysis process in high-throughput microscopy imaging.

•

We have developed system for detection of cavities in pulmonary x-ray images.

•

We have developed a system for the automatic assessment of carotid intima-media thickness in ultra-sound data.

•

We have developed new approaches for early diagnosis and prevention of woman breast cancer through computer aided diagnosis (jointly with Siemens Healthcare Sector) using parallel computing-based 3D image segmentation, as well as analysis of ultrasound images and case studies regarding woman breast cancer (jointly with the School of Health Sciences, UBI).

Computer Graphics The main research tracks within this area were tangible interaction, triangulation and rendering of implicit surfaces, water surfaces, molecular modelling, and MMOGs. The following is a list of contributions achieved in 2010: •

Multi-touch tabletop design. We have designed and constructed a multitouch tabletop, including the corresponding software, that allows for

167

running

interactive

applications

collaboratively

(jointly

We

have

designed

and

implemented an algorithm to track fingers without using markers. The idea is to be able to writing in-the-air as a mechanism of interaction in human-aware computing environments. •

Fluid simulation and rendering. We have developed and implemented new algorithms for the simulation and rendering of fluids for computer graphics and games applications, with a particular focus on water surfaces.

•

Molecular modelling and rendering. We have developed and implemented a constructive geometric method for DNA molecules, together with triangulation algorithms for molecular surfaces.

•

Rendering of implicit surfaces. A new algorithm for implicit surfaces with singularities was designed and implemented. This is an important for rendering

surfaces

with

topological

guarantees,

as

needed

in

mathematical packages as Mathematica and Matlab. •

Massively multiplayer online games (MMOGs). We have also developed an re-engineering software principle to easily turn a multiplayer FPS (first-person shooter) game like Quake into a massively multiplayer online FPS game using grid technology.

•

Browser-based

augmented

reality.

A

number

of

browser-based

interaction techniques were developed using augmented reality and WebGL (www.khronos.org/webgl). •

Fault tolerance in On-line Games. In spite of not being a critical application in the strict sense of the word, fault tolerance is a crucial matter because a fault in online game servers leads to a negative effect in the experience of the game. Players expect servers to be permanently available and that periods when it does not happen become reduced or even non-existent. Our work focus on exploring data and state replication contributing to on-line games availability in case of fault.

Pattern Recognition and Automatic Learning

Biometrics •

Work was developed on people recognition using biometrics. The biometrics traits considered were the iris as well as several traits obtained from a hand image, notably finger surfaces, palm print, hand geometry and palm veins.

•

Research in the field of secure biometrics was continued. In particular, the use of distributed source coding concepts and hash functions to secure iris and hand biometric data was investigated. This approach makes it possible to generate many different templates from the same iris or hand, which can be cancelled if they are compromised. Furthermore, it also guarantees that the original iris or hand data cannot be recovered from the stored data, thus guaranteeing its privacy.

•

Authentication

and

identification

of

emotional

states

based

on

electrophysiological signals and on computer interaction data, was another

important

area

of

research.

New

techniques

for

identification and authentication were explored using cross-parsing algorithms for similarity quantification. Also, a set up for ECG acquisition from fingers was implemented and tested, providing encouraging preliminary results. A system for the invocation of emotional states was developed, based on the playing of specific videos. Data acquisition is being performed in order to achieve a database for the evaluation of the assessment of emotion from electrophysiological data, namely EEG, ECG, and EDA. •

A system for biometric recognition and identification based on the ECG signal was developed and published. The approach is non-fiducial and based on information theoretic distances between symbol sequences, obtained by quantization (uniform or Lloyd) of the ECG signal.

•

Analysis of degraded data acquired in unconstrained conditions, namely without cooperation from the individuals to be identified. This puts in evidence a number of challenges associated with reliable biometric recognition.

We

have also

continued

our previous

work

on the

development of a non-cooperative multimodal recognition system. This 169

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

work has focused on gender recognition from face images, far infrared people tracking, far infrared face image segmentation and the analysis of the error rates regarding the accuracy of the segmentation stage of iris images. Kernel-Based Classification In this area of machine learning, we have carried out novel work in several directions. •

We have applied non-extensive information theoretic kernels that we have developed in recent years to several types of problems, including scene classification and shape recognition.

•

We

have

proposed

a

stand-alone

online

learning

algorithm, which is based on the kernelization of the recent forwardbackward splitting schemes. The proposed method iterates between subgradient and proximal steps. We also theoretically characterized the algorithm by proving regret, convergence, and generalization bounds. Compression Based Classification We have continued to work on classification of sequence data based on lossless compression algorithms of the Lempel-Ziv family (namely, the Ziv-Merhav method and the Cai-Kulkarni-Verdú methods for the estimation of relative entropy from sequences of symbols). Following the work carried out in 2009 on text classification, in 2010 we applied this class of methods to the classification of (quantized)

signals,

with

application

to

a

problem:

recognition/identification based on the ECG signal.

Clustering In the unsupervised learning area, research work during 2010 was devoted to the clustering ensemble approach and focused mainly on four directions, deeply grounded on similarity representations: •

The EAC (Evidence Accumulation Clustering) method was used as the baseline paradigm for the combination of clusterings. The probabilistic interpretation of the learned similarity – summarized in a co-associations 170

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

matrix – was explored, leading to a new soft clustering combination algorithm. •

The issue of clustering validity was explored in two directions: validity of partitions and validity of individual clusters within a partition. New measures of validity were proposed and tested within these two frameworks, either using statistical or dissimilarity based flavors.

•

Scalability

of

representations. The idea of dissimilarity

on

was further

analyzed and extended to higher order similarity measures. A theoretical analysis of the baseline definition of dissimilarity increments led to a new,

and

more

exact

expression

for

the

distribution of these increments. The new expression was integrated in two new clustering algorithms, one partitional and the other hierarchical, intrinsic probabilistic criteria having also been proposed for solving the parameter selection problem for these two algorithms. Information Theory and Estimation Theory We have continued to carry out fundamental research on the

intersections of

information theory and estimation theory and their applications in the analysis, design and optimization of communications systems and in physical-layer security. Speech Analysis •

We have developed a new method to deal with coarticulation in automatic phonetic transcription.

•

We have introduced a new automatic phoneme clustering method based on confusion matrices.

•

We have carried out a study of syllable structure in dysfunctional children speech.

Architectures and Protocols

Internet routing •

A mathematical model was put forward and theorems were derived to answer the seemingly simple question of finding the minimum number of links in a network whose failure interrupts the flow of traffic from any one node to any other. The problem is not trivial because routing policies render some paths in the network unusable to carry traffic and because these routing policies are realized with a routing protocol, the operation of which hides routes and paths.

•

Use of concepts from temporal logics to rigorously derive correctness and message complexities for the three main classes of routing protocols operated in the Internet: distance-vector (RIP); path-vector (BGP); and reset-on-failures (EIGRP).

•

Theory and practice of route aggregation. The Internet routing system is under heavy stress and in urgent need to scale. We proposed and evaluated the performance of novel route aggregation strategies applicable to both intra-domain and in inter-domain routing. The route aggregation strategies were validated with publicly available descriptions of networks and of the Internet as a whole, and show aggregation factors on the order of 90%. (JLS)

Transport protocols We analyzed the performance of TCP and TCP with network coding (TCP/NC) in lossy wireless networks. We build upon the simple framework introduced by Padhye et al. and characterize the throughput behavior of classical TCP as well as TCP/NC as a function of erasure rate, round-trip time, maximum window size, and duration of the connection. Our analytical results showed that network coding masks erasures and losses from TCP, thus preventing TCP's performance degradation in lossy networks, such as wireless networks. It is further seen that TCP/NC has significant throughput gains over TCP. In addition, we simulated TCP and TCP/NC to verify our analysis of the average throughput and the window evolution. Our analysis and simulation results 172

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

show very close concordance and support that TCP/NC is robust against erasures. TCP/NC is not only able to increase its window size faster but also to maintain a large window size despite losses within the network, whereas TCP experiences window closing essentially because losses are mistakenly attributed to congestion Wireless and sensor networks Design, analysis, and deployment of a routing protocol for opportunistic networks, exploiting device mobility to distribute data across the network.Development of a middleware architecture with service discovery features covering entertainment, security, communications and automation aspects.Research work related with plugand-play functionalities for IPv6-enabled wireless sensor networks was carried out. Cross-Layer approaches for WSNs were surveyed and several studies on Mac layer were performed. High-speed networks A new resource reservation protocol for OBS networks has been proposed and developed, and multimedia applications and security issues on multimedia applications were also addressed in our research activities. Networking and security issues in real-time applications This research stream focuses on problems related to high-speed network infrastructures and security issues for real-time multimedia applications in an evolution scenario where some applications and services have gradually migrated from the client-server paradigm to the peer-to-peer (P2P) computing paradigm. Particular attention was paid to the following issues: •

Autonomic and Real-time Detection and Classification of Encrypted P2P File Sharing Traffic and P2P TV Traffic;

•

Autonomic and Real-time Detection of Internet Traffic Anomalies;

•

Strategies for Robust Media Streaming over P2P Networks Based on Multiple Description Coding;

Vehicular Delay-Tolerant Networks In the area of Delay Tolerant Networks (DTN), we have proposed a new network architecture called Vehicular Delay Tolerant Network (VDTN). The main objective of this architecture is to provide a low-cost connectivity solution for isolated and dispersed regions with no networks infrastructure. The proposed architecture can be applied to various scenarios, including rapid deployment of emergency communication systems when all communication links have failed. The work on VDTNs is supported by the Internal Project VDTN@Lab, a joint collaboration between Covilhã and Aveiro groups. Our group is also involved on the NoE Euro-NF FP7-IST Project, leading the workpackage JRA 1.2 – Core and Metro Architectures and leading the Specific Joint Research Project VDTN; other partners are INESD-ID and UPC (Spain). Vehicular Networking A thorough understanding of the communications channel between vehicles is essential for realistic modeling of Vehicular Ad Hoc Networks (VANETs) and the development of related technology and applications. The impact of vehicles as obstacles on vehicle-to-vehicle (V2V) communication has been largely neglected in VANET research, especially in simulations. Useful models accounting for vehicles as obstacles

must

satisfy

a

number

of requirements,

most

notably

accurate

positioning, realistic mobility patterns, realistic propagation characteristics, and manageable complexity. We presented a model that satisfies all of these requirements. Vehicles are modeled as physical obstacles affecting the V2V communication. The proposed model accounts for vehicles as three-dimensional obstacles and takes into account their impact on the LOS obstruction, received signal power, and the packet reception rate. We utilized two real world highway datasets collected via stereoscopic aerial photography to test our proposed model, and we confirm the importance of modeling the effects of obstructing vehicles through experimental measurements. Our results show considerable obstruction of LOS due to vehicles. By obstructing the LOS, vehicles induce significant attenuation 174

interpretation of diagnostic tests and clinical decisions was proposed. The proposed measure is based on the amount of information contained in the differences between two observations. This measure is normalized and satisfies the flowing properties: it is a metric, scaled invariant and it has differential weighting. Moreover, evidence was given that grounded theory, together with mixed methods, can be used to involve healthcare professionals in the design and enhancement of access control policies to Electronic Medical Record systems. Physical-Layer Security We analyzed the role of jamming as a means to increase the security of wireless systems. Specifically, we characterized the impact of cooperative/friendly jamming on the secrecy outage probability of a quasi-static wiretap fading channel. We introduced jamming coverage and jamming efficiency as security metrics, and evaluate the performance of three different jamming strategies that rely on various levels of channel state information. The analysis provides insight for the design of optimal jamming configurations and indicates that one jammer is not enough to maximize both metrics simultaneously. Network Security Wireless networks that allow for coding operations to take place at intermediate nodes are particularly prone to active attacks by which malicious nodes inject erroneous packets to corrupt the information flows. Seeking a solution for this problem, we proposed a cooperative security scheme, in which neighboring nodes cooperate to detect misbehavior. In this so called "algebraic watchdog", each nodes observe the transmissions of other nodes and verifies whether they are complying with the coding operations foreseen by the network coding protocol. It can be shown that malicious behavior can be detected with high probability, as long as the errors introduced by the attacker outweigh the noise in the channel. If this is not the case, the errors can be corrected using forward error correction. 176

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

Random linear network coding can also be used in peer-to- peer networks to increase the efficiency of content distribution and distributed storage. However, these systems are particularly susceptible to Byzantine attacks. We quantify the impact of Byzantine attacks on the coded system by evaluating the probability that a receiver node fails to correctly recover a file. We showed that even for a small probability of attack, the system fails with overwhelming probability. We then proposed a novel signature scheme that allows packet-level Byzantine detection. This scheme allows one-hop containment of the contamination, and saves bandwidth by allowing nodes to detect and drop the contaminated packets. We compared the net cost of our signature scheme with various other Byzantine schemes, and showed that when the probability of Byzantine attacks is high, our scheme is the most bandwidth efficient.

Network Coding for Video Streaming Emerging practical schemes indicate that algebraic mixing of different packets by means of random linear network coding can increase the throughput and robustness of streaming services over wireless networks. However, concerns with the security of wireless video, in particular when only some of the users are entitled 178

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

to the highest quality, have uncovered the need for a network coding scheme capable of ensuring different levels of confidentiality under stringent complexity requirements. We showed that the triple goal of hierarchical fidelity levels, robustness against wireless packet loss and efficient security can be achieved by exploiting the algebraic structure of network coding. The key idea is to limit the encryption operations to a critical set of network coding coefficients in combination with multi-resolution video coding. Our contributions include an informationtheoretic security analysis of the proposed scheme, a basic system architecture for hierarchical wireless video with network coding and simulation results. We also presented an expression for the delay distribution of Random Linear Network Coding over an erasure channel with a given loss probability. In contrast with previous contributions, our analysis is non- asymptotic in the sense that it is valid for any field size and any number of symbols. The results confirm that GF(16) already

whereas

sizes

(e.g.requiring only XOR operations) induce heavy tails in the delay distribution. A comparison with Automatic Repeat reQuest (ARQ) techniques (with perfect feedback) is also included. Network Coding for Satellite Communications The broadcast nature of satellite networks such as DVB-RCS based systems provides a highly effective medium for content distribution, especially in the case of geographically scattered clients. Non-real-time services typically rely on application level protocols that often use forward error correction (FEC) and carousel data cycling schemes in unidirectional links. The presence of a feedback channel in satellite networks is mostly unexploited in the context of reliable multicast services. We showed that network coding protocols offer a native and transparent solution for reliable multicast over satellites. When employing a feedback channel, network coding can reach near real-time performance at an efficiency level close to known theoretical bounds for lossy satellite links. Capacity of Channels Shannon defined channel capacity as the highest rate at which there exists a sequence of codes of block length n such that the error probability goes to zero as n goes to infinity. In this definition, it is implicit that the block length, which can be 179

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

viewed as the number of available channel uses, is unlimited. This is not the case when the transmission power must be concentrated on a single transmission, most notably in military scenarios with adversarial conditions or delay-tolerant networks with random short encounters. A natural question arises: how much information can we transmit in a single use of the channel? We gave a precise characterization of the one-shot capacity of discrete channels, defined as the maximum number of bits that can be transmitted in a single use of a channel with an error probability that does not exceed a prescribed value. This capacity definition is shown to be useful and significantly different from the zero-error problem statement. Intelligent Transportation Systems Understanding driver behavior is critical towards ensuring superior levels of safety and environmental sustainability in intelligent transportation systems. Existing solutions for vital sign extraction are generally intrusive in that they affect the comfort of the driver and may consequently lead to biased observations. Moreover, low-complexity devices such as GPS receivers and the multitude of sensors present in the vehicle are yet to be exploited to the full extent of their capabilities. We presented a real-life system that combines wearable non-intrusive heart wave monitors with a wireless enabled computing platform capable of gathering and processing the data streams of multiple in-vehicle sources. Observed variables include electrocardiogram, vehicle location, speed, acceleration, fuel consumption, and pedal position, among others. Preliminary results show that the proposed system is well suited not only for characterizing driver behavior but also for identifying and mapping potentially dangerous road segments and intersections.

3D VIVANT

Title

Live Immerse Video-Audio Interactive Multimedia

Funding

EU, FP7

Descript.

The aim of the project 3D VIVANT is to capture events automatically in 3D and deliver them for realistic, interactive and immersive play back to home users-viewers. This will require the project to create, develop and integrate a comprehensive range of components from the generic technology of 3D imaging. Real and virtual 3D content will be homogeneously combined/mixed producing a novel form of rich and interactive content, defined as “3D Holoscopic content”. 3D Holoscopic imaging is a technique for creating full colour 3D optical models that exist in space independently of the viewer. The images exhibit continuous parallax throughout the viewing zone. The continuous nature of the images produced with this method eliminates the effect of 'cardboarding' (flattening of objects into discrete depth planes) and flipping (a visible effect created by moving between image fields) present

in

multiview

stereoscopic

systems.

Unlike

multiview

stereoscopy, information about a point is contained in many different parts of the image plane. In this respect 3D Holoscopic imaging is akin to holography. However 3D Holoscopic imaging is more advantageous, since it can operate under incoherent illumination, which is in contrast with holography, and hence it allows more conventional live capture and display procedures to be adopted. Furthermore, in viewing the 3D optical model accommodation and convergence work in unison (i.e. the viewer’s eyes focus and converge to the same point) to prevent eyestrain from occurring. The 3D VIVANT project will investigate the possibility of using different technologies for capture and display of 3D content. For the capture, 3D VIVANT will take full advantage of 3D Holoscopic imaging technology, where a single camera is required. Hence in this project a world first 182

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

single aperture ultra-high definition 3D Holoscopic imaging camera will be constructed which will permit live capture of 3D content. For the display, the project will take advantage of Holography to provide immersive, ultra high resolution presentation of 3D content. To increase the immersive experience, the generation and playback of 3D spatial sound is also investigated. The developed system will be tested using two user cases, namely, broadcasting and online hyperlinking. For this purpose various 3D Holoscopic video processing algorithms, such as 3D codecs and 3D object segmentation, as well as search and retrieval techniques will be developed.

The research work in this project is focused on 3D video stream adaptation methods capable of maximizing 3D perceptual quality under different sets of known constraints. The joint interdependencies between rate, 3D perceptual distortion and decoding complexity will be investigated using subjective evaluation and validation procedures. Adaptation of 3D video streams is mainly targeted at rate, format and decoding complexity adaptation, taking into account that 3D video includes more parameters suitable for adaptation which provide an increased level of flexibility (e.g., the 3D signal is coded into two streams which might undergo through different channel errors and constraints, variable depth distortion in the spatial and temporal domains producing similar perceptual quality, asymmetric distortion in stereoscopic video, effect of error concealment methods in 3D perception, etc). The project research is also concerned in devising power-aware

BioSec Secure Multimodal Biometric Recognition System using Distributed Source Coding

Funding

FCT/PTDC

Descript.

Biometric recognition systems target the automatic recognition of a person’s identity based on physical, physiological or behavioural characteristics (something a person is or produces). In particular, verification systems perform one to one authentication, comparing the captured biometric data with that person’s own biometric template (a mathematical representation of the biometric features extracted during the

enrolment

phase)

previously

stored

in

the

system.

One of the major vulnerabilities associated to biometric recognition systems is that once a biometric template becomes compromised, it cannot be reissued, updated or destroyed. An attacker could then gain access to all the accounts/services/applications using that same biometric trait. The main goal of the project is to create a secure multimodal biometric verification system, supporting the generation of different templates from the same biometric data, as well as cancellable templates. Furthermore, the privacy of the original biometric data needs to be guaranteed, not allowing its recovery from the stored data. State-of-the-art methods will be extended by considering a biometric verification system based on distributed source coding principles and cryptographic hash functions, to enhance security with respect to 185

Wireless sensor networks, made of tiny, low-cost devices capable of sensing the physical world and communicating over radio links, are significantly different from classical wireless networks such as GSM or wireless LANs: (a) the design of a sensor network is strongly driven by its particular application, (b) sensor nodes are highly constrained in terms of power consumption and computational resources (CPU, memory),

Previous work on fundamental aspects of wireless sensor networks has mostly focused on communication-oriented models, in which the sensor nodes are assumed to store and process the data, coordinate their transmissions, organize the routing of messages within the network, and relay the data to a remote receiver. Although some of these models provide useful insights (e.g. into the connectivity characteristics or the overall power efficiency of sensor networks) there is a strong need for formal methods that capture the inherent processing and memory constraints, and illuminate the massively parallel nature of innetwork computation. Our take is to develop process calculi for sensor networks building on formalisms for concurrent distributed systems and mobile code (most notably, pi-calculus). The envisioned tools will enable us to (a) prove the correctness and feasibility of different data 187

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

gathering and communication protocols (e.g. by exploiting behavioral equivalence between processes), and (b) carry out formal comparisons of different schemes by quantifying the minimum amount of required resources. Based on the results of the first task we will attack another fundamental problem in sensor networks: the need for sensor programming languages with self-configuration and distributed update capabilities. We propose to develop specifically tailored high level idioms for sensor networks that capitalize on notions such as mobile code and self-maintenance. Finally, we will implement and test the developed programming tools on a sensor networking prototype. Reallife experiments will allow us to better understand sensor networking constraints and further improve our designs. We believe that our interdisciplinary team of computer scientists and electrical engineers is well equipped to contribute both in theory and in practice to the advancement of sensor network programming.

This project addresses the problem of correct symbolic abstractions of cryptographic primitives for the purpose of symbolic, automated 188

proving of security properties of protocols. Computer security has been of major interest in the past two decades. This field provides both interesting research problems and important applications to everyone's life such as e-commerce and e-government, hence the need for designing better and safer security protocols. Proving security of protocols however is a difficult task that sometimes cannot be performed by hand, therefore several tools have been designed to deal with such a complex problem [B01,BMV05,P98]. But the need for such (automated) tools is not only due to the complexity of the protocols. If we consider the simple protocol proposed by Needham and Schroeder in 1978 [NS78], it was not until 1996 that Lowe discovered his famous attack on the protocol using the CSPmodel checker FDR [L96] and suggested a fix. The attack used a flaw in the protocol design, the encryption itself was assumed to be perfectly secure. With this ''perfect'' cryptography assumption the protocol is simple enough to be easily analyzed by standard model-checkers and theorem provers. The fix was shown to be safe as long as encryption was perfect. But what happens when the cryptographic primitives are not perfect, which is the case in real life where we can always guess a key with small probability? After some positive results regarding cryptographic soundness of such abstractions, Warinschi [W03] showed that the same attack discovered by Lowe against the NS protocol, could be performed against the corrected version if a somewhat weak but standard encryption scheme is used, the El-Gamal encryption scheme. This result turned the attention of the research community for the need of soundness results for formal cryptography, ie, the importance to characterize when protocols proved correct using perfect cryptography are correct when implemented with computational cryptography. Computational soundness of formal cryptography is an active research area and members of this team have been involved in several of its fronts [ABS05,ABHS05,ABHS09,AF06,AFGZN08,BHO07,BHO09,BMS06] Symbolic models provide abstractions for the study of cryptography that are amenable for automatic verification of complex protocols but assume ''perfect cryptography'' [DY93].

and

complexity

[GM84].

Computational

security proofs make use of techniques of these theories; proofs have to be done by hand (ie cannot be automated) and are different for each protocol. Good protocols are those in which attackers cannot do something bad too often and efficiently enough. This is a very detailed description, closer to reality as it involves the notion of efficient computation, hence complexity and probabilities. However, even for mildly complex protocols this approach simply becomes too difficult and impossible to handle. The unification of these two models is absolutely necessary for symbolic security proofs to be trustable. So far in the literature there are fragmented attempts done by different research groups, but as their treatment lack sound mathematical basis, the results themselves and how they are related are questionable AR02,ABHS09,AF06,BPW03,C01,CC08,DDMST05,MW04] We expect this research project to deliver new insights to the relationship between the symbolic and computational models, clarify the applicability and limitations of existing approaches to this problem, and provide sound mathematical foundations that can be used in the future as a common framework and technique for sound symbolic 190

Descript.

The grand objective of the research project DEWICOS: Design of Next Generation Very High Data Rate Wireless Communications Systems is to exploit a novel framework based on the interplay between information theory and estimation theory to lay the foundations for the design of next generation very high data rate wireless communications systems. In the last decade wireless communications have experienced an explosive growth with the demand for higher data rates to accommodate new services growing rapidly ever since. A number of wireless systems have been gradually introduced including novel mobile and fixed wireless systems, e.g., 2nd and 3rd generation mobile systems as well as WiFi (IEEE 802.11) and WiMax (IEEE 802.16). This wireless communications revolution is being fuelled by constant technological breakthroughs to enhance transmission performance in the wireless setting. For example, major advances that dominated research efforts in the past decade concerned the development of multiple antenna transmission schemes, as well as the development of powerful error correcting coding schemes, such as turbo codes and lowdensity parity-check (LDPC) codes. In fact, these powerful techniques are now gradually being incorporated into wireless communications standards and commercial products. Notwithstanding, the optimization of the reliable information transmission rate – the Holy Grail in communications – is still an open issue at large of paramount importance in communications systems research and practice, offering the prospect of communication at ever increasing information rates. The major difficulty relates to the absence of appropriate mathematical tools and methodologies due to the presence of complex features in communications systems, thereby motivating system designers often to resort to other criteria, engineering experience, and insight to optimize the system. Building upon foundational work on the interplay between 193

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

information theory and estimation theory, this project proposes a different paradigm to the analysis, design and optimization of wireless communications systems: We will capitalize on the relation between mutual

transmission rate between the input and the output of a system, and the non-linear minimum mean-squared error (MMSE), which measures the minimum mean-squared error in estimating the input given the output, to overcome in an innovative way the inherent difficulties concerning the optimization of the reliable information transmission rate of key communications systems. The research project is divided into three complementary tasks, which culminate with the application of the ideas to relevant communications scenarios and applications. The first task leverages the intersections between information theory and estimation theory in order to establish insight into the optimal structure of standard elements of communications systems. The focus will be on establishing concrete design guidelines for optimal transmit filters, optimal receive filters as well as resource allocation procedures in relevant communications scenarios, ranging from deterministic to wireless fading channels and single- to multi-user channels. The objective of the second task will be to develop practical algorithms, with a good tradeoff between issues such as accuracy, efficiency, complexity and convergence, in order to perform optimal filtering and resource allocation in communications systems. In addition, taking into account

that

achievable with powerful error correcting codes, this task will also investigate the integration of the optimal designs with powerful error correction codes, such as turbo codes or LDPC codes.

In the ears of an experienced physician, a stethoscope yields important clinical information which can help an initial assessment of a patient’s clinical condition and guide the subsequent need for more specialized exams. Auscultation is both a powerful tool for screening the generic population for cardiac diseases and a hard clinical skill to master. Our motivation is thus to address state-of-the-art digital audio signal processing research challenges for extracting clinical features from auscultation, as well as providing a clinical second opinion on specific heart pathologies. We pay particular attention to aortic pulmonary signal decomposition and its correlation with pulmonary arterial pressure, researching novel algorithms that can enable us to assist clinicians in the detection of pulmonary arterial hypertension situations. This is a good example of a reasonably common and sometimes deadly pathology that is difficult to detect by inexperienced physicians and which has a good prognosis when detected early.

As positioning devices, sensing technologies and wireless interfaces become standard commodities, all sorts of vehicles such as cars, buses and trucks will soon be able to operate in a networked fashion, sharing vital information ranging from traffic congestion data to accident alarm signals and making navigation and safety decisions based on the messages they receive from neighboring nodes.

The main objective of the research project Foundations of Future Communications Systems: Analysis, Design and Optimization is to explore a novel framework based on the interplay between information theory and estimation theory in the analysis, design and optimization of communications systems with relevance in practice. The advent of the information age has also been igniting the development of a whole telecommunications infrastructure to support the ubiquitous access to the Internet at ever increasing information rates.

All this data will be further analyzed applying clustering techniques for exploratory data analysis, crossing it with the different types of mechanical loads.

The key insight is that although the quality of the captured data possibly denies the positive recognition with enough confidence, perhaps it is still possible to assure that data is not correspondent to a subset of the enrolled templates, which for most of the everyday situations is the essential.

Next Generation Network Operations and Management

Funding

FCT/CMU

Descript.

Effective network management has been widely recognized as a grand challenge. Enterprise networks spend an increasing amount of their IT budgets (up to 70% in 2008) in order to only maintain their current operating environments, rather than to add new, value-adding services and equipment. A $1000 server that demands annual maintenance cost of $2000 illustrates a simple example of the management problem. This excessive cost of network management is mainly due to the large scale of networks, the heterogeneity of different technologies, and their subtle interactions. The goal of NeTS is to develop a novel network operation and management framework that departs from conventional approaches through a cross-disciplinary research collaboration based on hierarchical network abstraction modeling, structure learning of probabilistic graphical models for machine learning, and wavelet and kernel-based signal processing technologies. In multiple phases, NeTS will be progressively deployed in the Portugal Telecom (PT)’s operation and management of high definition IP/TV network to illustrate the impact of our proposed research. High Definition IP/TV network is one of the highest growth services for PT and is regarded as a key strategic area in PT. The grand challenge of this complex network is to deliver, 205

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

without failures, a high quality service efficiently – this requires novel management/operations systems to detect anomalies, identify their root-causes, and predict future network behavior in real time. Existing network management systems for IP/TV are generally focused on monitoring and on simple correlation of events analysis; using these management systems still incurs in excessive costs and delays. NeTS will be deployed online in part of PT’s IP/TV network in order to assess its performance and expected network operations and management cost reduction. Network operators will play a key role in assessment and fine-tuning of our systems. Our approach to this research problem is significantly different from conventional approaches that focus on monitoring and correlation analysis. We bring together insights from network abstraction and statistical and heuristic machine learning methods and closely tie them to build an intelligent network abstraction model. Network insights show that the network configuration dictates the behavior of the network control plane and the network control plane dictates the behavior of the data plane. We bring configuration, control and data plane abstraction models together with probabilistic graphical models to derive an intelligent and predictable network abstraction model of an enterprise network. Further novelty of our approach consists of performing automatic learning of the graph structure using concepts from Bayesian model selection, information theory, and optimization; this will be done step-by-step using first static network configuration elements, then by summarization and filtering of dynamic control plane information, and finally of data plane information. Once a graphical model is obtained for the network, we will perform inference on the graph to identify anomalies and their rootcauses and to predict future network behavior. Finally, we will explore the concept of forcing function to impose restrictions on the network configuration that simplify the graphical model and the inference process. This project heavily leverages on previous network abstraction modeling work with PT in last 3 years. The direct impact of this research will be on the network operations and management of PT’s IP/TV service. Although at this point it is not possible to say what the real impact will be, we anticipate a reduction of at least 30% on 206

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

network operations and management costs. This is supported by the anticipation that support teams will be directed to a single extremely likely root cause of a failure rather than to multiple possible failure points, that root-causes will be detected in the time-span of seconds rather than days, that service may be brought up in minutes s rather than days, and that network behavior and failures may be anticipated, thus reducing down time several orders of magnitude. We expect other enterprise network-supported services may also benefit from NeTS because the network modeling and management functions researched in

networks.

To achieve NeTS’ goals, we formed an interdisciplinary team that includes experts in Networking (Dr. Sobrinho, IT/Lisboa, Dr. Kim, ECE/CMU and Dr. Alegria, PT), Machine Learning (Dr. Cardoso, INESC/Porto

We plan to integrate several PhD students who are already enrolled in (e.g. Tiago Carvalho and Tiago Quelhas) and in the process of applying to the CMU-Portugal program. It is also important to note that we have created various PhD-level courses within the CMUPortugal program in topics directly relevant to this research proposal, as well as taken the responsibility for advanced courses within the CMU-Portugal Master’s program in Information Networking. Class projects for graduate and undergraduate students will also focus on research issues that contribute to the success of NeTS. Furthermore, PT employees who are enrolled in the Master’s program will work on NeTS projects and continue their work when they return to PT after completion of their degrees. CMU and Portuguese PIs will ensure that project development, milestone achievement, and partner coordination are on track with plan and take measures to correct any deviation to the project timetable. This will be facilitated by the existence of previous work between partners e.g. PT and CMU and shared PhD 207

This triggered interest in wireless sensor networks (WSN) where large collections of such small wireless sensor nodes are scattered across critical geographical areas or infrastructures to execute a variety of monitoring and acting tasks. While the use of WSN is crucial to assess the state of a physical system, the ultimate engineering goal is to control such system to perform certain desired tasks. We refer to systems that close the loop around

To realize the immense potential bene ts of CPS in real-life applications, a plethora of novel problems lying at the intersection of statistical signal processing, control, communication theory, and distributed optimization, must be addressed. Indeed, it is clear that to achieve desired networkwide detection, estimation or control objectives, system designers should deal eciently with simultaneous challenges, typically 208

interconnecting the sensing nodes, dealing with the random nitebandwidth wireless medium, etc. The need for this interdisciplinary e ort is mirrored in the creation of this project's research team which gathers signi cant expertise in a wide range of complementary topics in the disciplines of control, signal processing, optimization, information theory, along with the private technology company ISA (Intelligent Sensing Anyhwere) which holds a vast experience in the deployment of sensing networks for telemetry, environmental monitoring and energy eciency. The main goal of this project is to address certain key research issues in the eld of wireless sensor networks and map the research results into implementations on prototype testbeds, thereby showcasing real-life applications with social and economic impact. More precisely, the expected outcomes of this project are: 1. Fast algorithms for sensor selection While energy-eciency is of a lesser concern in wireless LANs, it is of critical importance in large-scale wireless sensor networks (WSN), as the in-situ unattended sensors are typically powered by nonrechargeable batteries. Thus, aggressive restraints on sensor usage must be observed to ensure a prolonged WSN lifetime. When the WSN is used for event discrimination (e.g., intruder/no intruder, re/no re, etc) this translates into nding which minimal subset of the deployed sensing nodes is sucient to activate for a given query, whilst securing a prescribed detection performance. It is clear that nding the optimal subset of sensors represents a formidable optimization challenge. Indeed, forming all possible combinations of few sensors and checking the respective performance is computationally intractable even for moderate network sizes. Additionally, a WSN is typically immersed in a noisy environment

209

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

subject to various degradation factors such as wireless fading and interference phenomena. These induce communications constraints between the sensors themselves or between the sensors and a fusion point responsible for the decision. It is thus important to explicitly account for the impact of this adverse phenomena in the design of reliable sensor selection algorithms. In this project, we will develop fast (non-combinatorial) optimization algorithms for several sensor selection application scenarios which strike a desirable tradeo among detection performance, computational complexity and robustness with respect to the fading wireless medium. 2. Secure WSN communication schemes Security is an issue of paramount

importance

in

current

communications

systems

and

networks. The wide deployment of wireless sensor networks, together with the broadcast nature of the wireless medium, calls for advanced secure mechanisms to protect potentially sensible information against possible eavesdroppers. Traditionally, security is viewed as an independent feature with little or no relation to the remaining data communication tasks and, therefore, state-of-the-art cryptographic algorithms are insensitive to the physical nature of the wireless medium. However, there has been more recently a renewed interest on information-theoretic security - widely accepted as the strictest notion of security - which calls for the use of physical-layer techniques exploiting the inherent randomness of the communications medium to guarantee both reliable communication between two legitimate parties as well as secure communication in the presence of an eavesdropper. This paradigm is particularly interesting for wireless sensor networks since it may not be possible to secure information using state-of-the-art complex cryptographic protocols due to energy budget considerations. In this project, we will study the fundamental

security

mechanisms

pertaining

to

the

sensor

network communications medium by exploiting tools from information theory. In addition to revealing the secrecy limits of wireless sensor networks, we will also construct speci c transmission schemes

210

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

appropriate to convey information between sensors and a fusion point in a reliable and secure manner, taking into account the energy and bandwidth restrictions of sensor networks. 3. Secure Control of Cyber-Physical Systems Modern cyber-physical systems raise signi cant engineering challenges because of their scale, their need to bridge the physical, information and communication technology domains and their need to operate eciently, securely and reliably. Today's methods and tools for control systems engineering are unable to systematically cope with such requirements. Security, in particular, must enter the design process and cannot be considered an afterthought. Today's designs are mainly driven by performance/cost considerations, resulting in brittle systems susceptible to attacks starting from both the physical and cyber side. The problem arises because CPS tend to be open systems, accessible both physically and through the communication network. The increasing use of the Internet will allow attackers to execute their attacks remotely. Next generation systems

will

be

particularly

susceptible

to

security

threats

if this concern is not addressed at design time. CPS, di erently from traditional IT systems, not only have to be able to detect malicious attacks but they need to guarantee continuity of operations under attack,

perhaps

functionality,

through

degradation rather abrupt. They also need to be able to recon gure to eradicate attacks and restore full functionality. We propose to introduce a

approach

This infrastructure will allow us to validate the proposed methodologies and algorithms in a real setting, to assess its robustness to uncertainties and resilience to security attacks.

This project addresses the emerging 3D TV broadcasting services by investigating the problems associated with transmission of different stereo video coding formats. It is comprised of two main parts that run in parallel and communicate between each other by exchanging technical information in order to optimise the performance of the broadcasting system in terms of received quality and channel useful capacity. The research on 3D video deals with characterisation and optimisation of 3D video coding algorithms by developing and testing suitable error resilience methods for broadcasting such type of content. On the decoder side the project addresses error concealment methods to cope with transmission errors and improve the quality delivered to users. The particular issues related to coded depth information are receiving special attention in this project as this is the major component of 3D video which makes it different from classical 2D. Appropriate distortion measures for depth will be used to optimise performance. The project makes use of the most recent video coding standard for video (H.264/AVC) and its extension for multiview coding (H.264/MVC). Finally, a method to characterise the radio propagation channel will be developed for varying deployment scenarios. A refined method is required to effectively measure the signal coverage in DVB-T networks and to extract the effective parameters for the error pattern generator required for both source and channel coding optimisation of DVB-T transmissions. Additionally, the measured data to be obtained and included in a database for various geometries and at a number of frequencies will represent a quantum improvement, both in volume and accuracy of the database presently available to system designers. This will form a framework to radio system designers to propose fading mitigation techniques based on link level analysis using the proposed

QuantPrivTel: Quantum PrivateTelecommunications

Funding

FCT/PTDC

Descript.

QuantPrivTel – Quantum Private Telecommunications is a research project that joins the theoretical expertise of the Security and Quantum Information Group (SQIG) at Instituto de Telecomunicações (IT) in Lisbon and the skills in quantum optics experiments of the Optical Communications group (OC-Av) at IT Aveiro to tackle new challenges in the

emergent

and

multidisciplinary

area

of

quantum

private

telecommunications. Its main scientific objectives are: 1. To propose new quantum protocols for important problems of privacy in telecommunications that cannot be solved with the now-famous quantum key distribution, namely the authentication of classical messages

with

enhanced

security

and

fair

contract

signing;

2. To develop and implement efficient methods to generate and detect single photons in optical fibers, as well as pairs of entangled photons, and to use them to demonstrate in the laboratory our original quantum protocols

for

message

authentication

and

fair

contract

signing.

Some contributions are also expected to more general and forwardlooking problems, such as new schemes to improve phase estimation and precision measurements based on phase distinguishability and quantum correlations, and their possible applications to positioning systems and satellite communications, or the design of environmentassisted quantum channels, a very novel idea we intend to explore.

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

Descript.

The goal of the project is to advance the state of the art in criteria and algorithms for solving imaging inverse problems. The research fronts that we aim to push forward are the following: a)

In

standard

photography,

and

even

more

in

computational

photography (CP), deconvolution plays a key role. In the standard case, deblurring is used to compensate lens softness, while in many CP applications (e.g., coded aperture) deconvolution is itself responsible for producing the images. Even with the CP ''friendly'' direct operators, prior knowledge (regularization) is required to solve the IP. In this work front, we will develop new regularization criteria, beyond the currently used sparseness-inducing 1-norm and total-variation. In particular, we will consider: compound regularizers; criteria that adapt automatically to the intrinsic complexity and/or the local structure of the underlying image; non-local regularization (which has only been used for pure denoising problems, with excellent results). b) Realistically, full knowledge about the convolution operator is seldom available: the exact motion causing a motion blur is of course unknown; coded aperture imaging is highly sensitive to the exact knowledge of the aperture, which is usually obtained by a previous careful calibration procedure. These observations stress the general importance of blind deconvolution. In this topic, we will research criteria for blind deconvolution, for problems with varying degrees of uncertainty about the direct operator. In particular, we will take steps towards the ''holly grail'' of blind deconvolution: an objective function whose minimization yields optimal image and convolution estimates. c) Some of the currently fastest algorithms for CS and image deconvolution

under

standard

regularizers

were

developed

by

researchers in the project team. The new criteria mentioned in (a) and (b) will result in new, more challenging optimization problems, requiring new algorithms. This will be the third core research direction of the project, continuing our successful recent line of work. Bregman iterations and augmented Lagragian methods will be fundamental tools in our quest.

SearchCol SearchCol: Meta-heuristic Search by Column generation FCT/PTDC Many relevant practical problems can be modeled as combinatorial optimization problems (COPs). Examples are the definition of routes for vehicles,

schedules

for

machines,

or

the

dimensioning

of

telecommunication networks. Meta-heuristics (MHs), such as tabu search or genetic algorithms, are the most successful methods in providing good-quality solutions in reasonable amounts of time for large-size instances of several COPs. The aim of this project is to propose a new MH, entitled Search by Column generation (SearchCol), for COPs. SearchCol algorithms will be applied in specific problems from four areas: production planning and scheduling, telecommunications, forest management, and cutting and packing. The main distinctive feature of SearchCol is that its ingredients (such

as

construction

of

solutions,

neighborhood

structures,

or

crossover operators) are based on column generation (CG). We aim at proving that a suitable search strategy (provided by the hybrid MHs framework) taking advantage of decomposition exact methods (CG) quickly leads to high-quality solutions for NP-hard COPs. The evidence is that CG provides tight lower bounds (in minimization problems) on the optimal value and that the columns belonging to the restricted master problem define a search space where high-quality solutions exist. The drawbacks of standard MHs (the lack of ameasure of the quality of the solution obtained and the lack of a well defined stopping criterion) are overcome in SearchCol since the lower bound provided by CG is available.

SIMBAD Beyond features: similarity-based pattern analysis and recognition 217

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

Funding

EU, FP7 ICT

Descript.

The challenge of automatic pattern analysis and recognition (or machine learning) is to develop computational methods which learn to distinguish among a number of classes from examples, with a view to endow artificial systems with the ability to improve their own performance in the light of new external stimuli. This ability is instrumental in building next-generation artificial cognitive systems which, as opposed to traditional machine or computer systems, can be characterized as systems which cope with novel or indeterminate situations, which aim to achieve general goals as opposed to solving specific problems, and which integrate capabilities normally associated with people or animals. The socio-economic implications of this scientific endeavor are enormous, as it will have applications in a wide variety of real-world scenarios ranging from industrial manufacturing to vehicle control and traffic safety, to remote and on-site (environmental) sensing and monitoring, and to medical diagnostics and therapeutics. This project aims at bringing to full maturation a paradigm shift that is currently just emerging within the pattern recognition domain, where researchers are becoming increasingly aware of the importance of similarity information per se, as opposed to the classical feature-based approach. Indeed, the notion of similarity has long been recognized to lie at the very heart of human cognitive processes and can be considered as a connection between perception and higher-level knowledge, a crucial factor in the process of human recognition and categorization. We shall undertake a thorough study of several aspects of purely similarity-based pattern recognition methods, from the theoretical, computational, and applicative perspective. We aim at covering a wide range of problems and perspectives, considering both supervised and unsupervised learning paradigms, generative and discriminative

models,

and

our

interest

will

range

from

purely

theoretical problems to real-world practical applications. We shall apply our algorithms to challenging biomedical problems that lend themselves particularly well to similarity-based approaches, namely, to the analysis of tissue micro-array images of renal cell carcinoma and to magnetic 218

TRAMANET – Traffic and Trust Management in Peer-to-Peer Networks

Funding

FCT/PTDC

Descript.

The objectives of this project are the following: 1) Development of a methodology to detect P2P file-sharing traffic in local area networks for further blocking of its source. As far as we know only limited solutions for this problem are available, which lead to large performance degradations even at moderate network speeds (e.g. 100 Mbits/s). The methodology to be developed might be validated in an experimental environment. It is expected that the method and apparatus for the detection of P2P traffic should result in an international patent. 2) Proposal of a new trust mechanism for P2P system, taking into account the dynamic properties of peers and avoiding a large traffic overload. A trust model addressing both problems is lacking. The new trust model based on dynamic weights for P2P networks will be investigated in order to overcome both problems. 3) Development of a framework for vulnerability assessment of peers and their trust mechanisms. This work is pioneer and will study the effects of system

Descript.

The objectives are to maximise resource transmission efficiency whilst guaranteeing the quality (of experience) and minimising the effort for each entity/operator. In line with these objectives, optimization mechanism account for: • Information from the different protocol stack layers to optimize the 219

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

subscriber access performance, and the creation of cross-layer design interactions whilst optimizing the quality of experience (QoE) metrics; • Interaction among the different network entities to make the service available to the subscribers in an optimized way, taking the possibility of having different companies operating the backhaul and the access networks. The focus of the research activities will be the following: • To identify, monitor and optimize QoE metrics for voice and video services in these networks by considering the support of an hierarchy of mesh networks for the identified scenarios; • To define cross-layer mechanisms to optimize the impact of the developed QoE metrics into the concatenated mesh network performance. Our research will explore mechanisms for efficient use of spectrum, for the shared medium access and routing onto the concatenated networks, transport issues, as well as the usefulness of context awareness, e.g. positioning,

the

distribution

of

velocities

and

services;

• To apply game theory concepts to optimize the cooperation among the different agents: subscriber terminal access network nodes (gateway to the operator) and backbone network routers; • To use pricing models to analyse the benefit associated with agent as well as the interactions among different network operators through the use of the optimization methodologies previously proposed.

The work to be developed in this project relates to the topic of global mobility management in spontaneous wireless environments, i.e., environments that self-adjust to any network topology change. Global mobility management is addressed from a network perspective, and the purpose is to ensure a transparent access to Internet services (e.g Triple Play) for the end-user, who will be able to access his/her subscribed services independently from access attachment point, location, and

220

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

based upon his/her own requirements (“Quality of Experience”, QoE). In addition, global mobility management is to be analyzed from a decentralized perspective, given that environments to be considered will incorporate wireless local-loops that are based upon end-user willingness to cooperate. Main aspects to focus upon are: 1. Handover management optimization a. Consider QoE as well as available (aggregated) spectrum to provide the user with the best possible connection seamlessly at any time and independent of location, having in mind user expectations. b. Analyze and validate adequate cost functions and metrics to estimate QoE levels on-the-fly. 2. User-centric mobility management a. Investigate and validate algorithms for a self-organized selection of anchor-points, aiming to insure system robustness to highly frequent changes. b. Devise a global mobility management mechanism taking into consideration the aspects analyzed in relation to handover optimization and incorporating mobility models that support adequate anchor point selection.

VERE: Virtual Embodiment and Re-Embodiment

Funding

EU, FP7 ICT

Descript.

This project aims at dissolving the boundary between the human body and surrogate representations in immersive virtual reality and physical reality. Dissolving the boundary means that people have the illusion that their surrogate representation is their own body, and act and have thoughts that correspond to this. The work in VERE may be thought of as applied presence research and applied cognitive neuroscience, and it would also significantly add to scientific knowledge in these areas . Imagine that you could transfer your self to an artificial body – a virtual body as represented in virtual reality or a physical robotic body. Recent

221

ANNUAL REPORT 2010 – NETWORKS AND MULTIMEDIA

advances in cognitive neuroscience show that internalising a body beyond ourselves (external, remote, alien) is possible, that our body representation is highly malleable and may be altered by appropriate changes to the normal stimulus contingencies that we are used to in every day life. The purpose of this research is to make such body transference possible with two different modes (virtual and physical). On top of this technical achievement, that would be underpinned through ongoing neuroscience research on body representation, would be a number of practical applications that will be constructed and investigated during the project.

4.4.3.2 Applied Mathematics Research was developed in the following fields of Mathematics: Optimization and Numerical Linear Algebra. Apart from some more theoretical oriented studies, our research

has

mainly

been

focused

in

the

design,

convergence

analysis,

implementation and testing of algorithms for the solution of many important problems in these areas. We have also been collaborating with researchers of other areas in the design and solution of some models of engineering and finance. The most relevant topics are presented below. •

Numerical Linear Algebra: Preconditioning and convergence of iterative methods for the solution of linear systems of equations.

•

Complementarity

Problems:

design,

implementation,

convergence

analysis implementation and testing of interior-point algorithms, activeset methods, sequential quadratic algorithms and enumerative methods. •

Global Optimization: complementarity algorithms, positive semi-definite and reformulation-linearization techniques for bilevel programming, quadratic and bilinear programming and mathematical programs with complementarity constraints.

•

Discrete

Optimization:

global

optimization

algorithms

for

linear,

nonlinear and complementarity problems with integer variables. •

Solution of Structured Optimization Models, namely finance models and eigenvalue complementarity problems.

•

Design and solution of models in telecommunications. 280

ANNUAL REPORT 2010 – BASIC SCIENCES AND ENABLING TECHNOLOGIES

Security and Quantum Information During 2010 research on Security and Quantum Information was carried out in the following topics: A-Logic •

Parallel composition of logics. Capitalizing on the graph-theoretic account of logic systems and their fibrings, and inspired on notions of concurrency, composition

a novel form of combination of logics — parallel —

at

the

semantic

level

was

investigated.

This

combination mechanism allows both symmetric (like sharing) and nonsymmetric (like triggering) forms of interaction to be specified at the signature level, and subsumes fibring as a special case. The conservative

nature

synchronization

using

of

parallel

a

generalized

composition bisimulation

under

lossless

technique

was

established. •

Graph-theoretical account of logic calculi as generalized 2-categories. First steps were taken towards a graph-theoretical treatment of deduction.

•

Importing logics. The notion of importing logics was introduced, subsuming as special cases several kinds of asymmetric combination mechanisms,

like

temporalization,

modalization

and

exogenous

enrichment. This novel logic combination mechanism is then proved to be strongly conservative. •

Abstract algebraic logic. The development of the behavioral approach to abstract algebraic logic was continued, namely by proposing an algebraically well-behaved notion of valuation semantics and showing that it parallels in richness the well-known theory of logical matrices and their connection to the traditional approach to algebraic logic. Algorithmic aspects of logics defined by possibly non-truth-functional finite-valued valuation semantics were also studied.

B-Complexity •

Computability in dynamical systems. Results relating classical topics from dynamical systems theory (Smale horseshoe, stable manifold theorem, domains of attraction) with computability were obtained.

•

Analog computation and verification. Lower and upper bounds on the computational power needed to solve the reachability problem for Lipschitz

dynamical

systems

operating

under

the

presence

of

perturbations were established. •

Sophistication for infinite sequences. A new definition of sophistication for infinite sequences was proposed. The set of sequences with sophistication equal to zero was shown to have Lebesgue measure one and it was also proven that the set of sophisticated sequences is dense. The set of deep infinite sequences was shown to be dense. Finally,

it was proven that sophistication and depth for infinite

sequences are distinct information measures.

4.4.3.3 Instrumentation and Measurement Scope and Objectives The Instrumentation and Measurement Group works in the broad domain of Metrology. In 2010 the main topics addressed were: •

Analogue-to-digital and digital-to-analogue conversion;

•

Measurement of electrical quantities;

•

Non-destructive testing

•

Sensors and transducers;

•

Signal acquisition and automated and telemetric measuring systems;

•

Signal processing applied to sensors and instrumentation.

•

Swarms robotics

Measurement of electrical quantities •

In the context of a contract, a DSP based three phase power quality analyzer was implemented. The device is to be used within a commercial product and it will monitor power quality in accordance with the norms and to assess the quality of service in multiple locations in the power distribution grid.

Non-destructive testing •

The research work during 2010 was mainly related with the PTDC/EEAELC/67719/2006 and I.T. internal project CLASSE that aim at classifying defects inside conductive non-magnetic plates. The application was extended to determine thicknesses. A new constant field probe was designed. This probe is based on the generation of a sinusoidal magnetic field with constant amplitude inside a limited area, and the detection of the secondary field accomplished with a bridge of giant magneto-resistor sensors. The new probe was registered in the patent PT104826. Another important aspect of the work carried out was related to the so called quantitative non-destructive evaluation QNDE of defects in metallic materials. In this work the aim was not related to the detection of defects, but mainly to the characterization of those defects in a quantitative way. Thus, by using direct problem solvers that are enough simple to be included in an iterative cycle, the solution of the inverse problem was attempted. This case study was related to the geometrical characterization of a straight crack in an aluminium plate. The use of algorithms implemented using DSPs to process and interpret sensors data proved to be very effective to overcome their poor performance. Significant improvements in the crack position accuracy 283

ANNUAL REPORT 2010 – BASIC SCIENCES AND ENABLING TECHNOLOGIES

and resolution were obtained. Some of the crack characteristics like length and orientation are now obtained using the measurement system developed at the Instrumentation and Measurement Laboratory. Novel low-cost handheld instruments to detect cracks and other defects in a plate of conductive material have been implemented and the prototypes are working properly. One of these instruments uses a planar excitation coil with a giant magnetoresistor as the sensing element and the visualization of the defect can be depicted in real-time on a LCD display. Besides the output voltage with the sensor location can be transmitted to a PC for further processing. The other instrument is able to measure both amplitude phase of the sensor output voltage (corresponding

A new dsPIC based impedance measurement systems was designed, developed and implemented for a viscosity sensor. The principle of operation of the sensor is based on a vibrating wire immersed into the liquid whose viscosity is to be measured. The characteristic of the sensor that is changed by the liquid viscosity is the impedance resonance frequency as well as the width of the resonance. Since the measurement is done on a wire, the amplitude of the impedance is very low which requires special care in the design of the analogue interface of the measurement system and carefully designed calibration procedures. Progress in the interoperability of marine observatories has been carried out.

Sensor data is collected at different world locations and large streams of data must be correlated with other events or data sources to study either long term tendencies or singular events. To allow this analysis data in a location context must be time-stamped. For many observations a low time-stamp precision is adequate but, for other observations, like hydrophones and seismometers, the millisecond precision level is needed. Now the project and implementation of a “GPS virtual pulse-per-second signal generator” to be installed at OBSEA observatory to timestamp sensor data in a submillisecond range is being carried out.

4.4.3.4 Integrated Circuits and Systems Scientific activities under this topic followed six lines described in the following sections. In some cases, the actions taken resulted also on industrial contacts at both national and international levels.

ANNUAL REPORT 2010 – BASIC SCIENCES AND ENABLING TECHNOLOGIES

Energy Efficient Concepts for Public Illumination Systems This topic represents a new trend on the usual activities of this group. It departed from the gathered knowledge on solid state lighting devices, LEDs, also explored for other objectives. Public illumination systems are predicted to be dominated by solid state lighting devices in the next few years. LEDs, present several advantages to other illumination devices in current use. The exploitation of these advantages and the advancement of collaborative control strategies for these systems are currently a hot topic for both research and industrial sectors. The activities under this line of research started with the participation on an International funded project, involving several participants from the European community (project LITES: CIP-ICT-PSP2008-2/238916). The major achievements under this line of research are the dissemination of the group activities both at national and international levels, and the direct contact of several actors from the industrial sector that may result in future collaborations. Energy Efficient Integrated Circuit Amplifier Design This line of research results from the gathered experience of this group on the field of integrated circuit design. The main objective is to advance new design strategies able to optimize circuit performance without impairing power consumption. The expected outcome will be to achieve energy efficient amplifiers. Until this point the research on this line was concentrated on the analysis and deployment methods for minimum power consumption in amplifiers. This line of researched is supported on a national funded project (project EECCO: PTDC/EEA-TEL/105314/2008). Tdoa Telemetry for Wildlife Tracking Systems Traditional telemetry solutions for wildlife tracking and surveillance resort to two main approaches: RF tracking systems, and GPS based data loggers. RF tracking systems are crude and require human intervention. On the other end, GPS based data loggers have the ability to be very accurate, but they are also very expensive. Moreover, GPS based systems are not a god choice for small animals (as for instance the case of small birds). This has led the Integrated Circuits group members to advance a new solution able to deliver accurate position information, and to reduce the volume of the identifiers. This solution is based on TDOA (Time Difference Of Arrival) measurements. Initial research as demonstrated the feasibility of our intents. It was also established a close cooperation with 289

ANNUAL REPORT 2010 – BASIC SCIENCES AND ENABLING TECHNOLOGIES

researchers from Biology. This line of research has result on a project proposal (project BIRDS: PTDC/EEA-TEL/120831/2010). Saw Based Sensors Development and Design Under this line of research the main objective is to develop SAW based sensors, using diamond film layered structures. Diamond films are especially interesting due to their resilience to adverse conditions. This line of research resulted from the cooperation of the Integrated Circuits group with researchers from the Mechanical Engineering department at the University of Aveiro. The activities under this line of research are under the framework of a national funded project (project JISIS: PTDC/EEA-TEL/104004/2008). Radio Astrnomy Methods for Deep Space Exploration The research under this line has proceed through three main project lines: i) The GEM project: test of COTS based digital complex cross-correlator for polarimetry application and ultra-low noise LNA manufacture; ii) The SKA project: test on site in Moura of SAR based Aperture Arrays (with the presence of the President of the Republic), with Nokia Siemens Networks ICT contribution. Co-Supervision of engineer on signal transport design for SKA network (40G, 100G); and iii) The CorE - Cosmic Origins Explorer, an M3 proposal study for the next generation of microwave space probes, submitted to ESA. The mission was later selected by ESA for further analysis (Member of the scientific Consortium). Visible Light Communication System Design The research under this topic has started several years ago, with project VIDAS (PTDC/EEA-TEL/75217/2006). The main objective of this project was to explore visible light as a communication means for driver assistance systems. Traditional lighting devices are not suitable for communication purposes due to their persistence between switching states. This is the case of both incandescent and discharge devices. LEDs, on the other end, enable fast switching operation, thus potentiating other applications rather than lighting. VIDAS project elaborated use LEDs for both signaling and communication purposes. The research on this topic is reaching to important conclusions. A real demonstrator was assemble to show that visible light can be used for communication at low data rates, and also, that

290

ANNUAL REPORT 2010 – BASIC SCIENCES AND ENABLING TECHNOLOGIES

evolved modulation techniques, such as spread spectrum, are required to combat the presence of noise (especially on outdoor scenarios). Design Automation applied to Optimal Circuit Sizing A new design automation tool, based on a modified genetic algorithm kernel, in order to improve efficiency on the analog IC design cycle was developed. The proposed approach combines a robust optimization with corner analysis, machine learning techniques and distributed processing capability able to deal with multiobjective and constrained optimization problems. The resulting optimization tool and the improvement in design productivity was demonstrated for the design of CMOS operational amplifiers. Design Automation applied to Class-D Amplifiers Topology Exploration and Circuit Sizing An automated design methodology for continuous time loop-filters dedicated to Class-D amplifiers, aiming the optimization of both THD and noise was defined. This methodology is based on a modified genetic algorithm kernel, and a set of performance rules that integrates both the topology selection and circuit sizing by automatically generating and sizing filter topologies to minimize the loop THD and noise, but replacing traditional and very long transient and steady-state simulations by fast AC evaluations. The evolutionary algorithm accepts any kind of SPICE like simulator as its evaluation engine, multiple filter topology templates and a set of design constrains and fixed component values can be included on the process adding flexibility. The approach was demonstrated for the design of a fully differential BTL class-D loop filter topology that achieves less than 0.003% THD at 680mW output power while maintaining the base-band noise term below 4ìVms. DC/DC Converters for the Space Industry The design of state-of-the-art DC/DC converters for low power applications for aerospace industry was initiated baring in mind the integration of the control circuit of the DC/DC converter. A first silicon prototype was released by the end of the year.

4.4.3.6 Power Systems Fault Analysis and Development •

Of wind turbine power conversion systems based on permanent magnet synchronous generators – Due to arising interest on renewable energy systems and considering the complex power converter systems used in these specific drives, in this research area, special attention is given to the faulty analysis of these power conversion systems. A theoretical analysis was carried out through computational simulations. Moreover, some laboratory tests were also performed, being the drive performance investigated by the analysis of some key parameters.

•

Of power converter faults – Variable speed ac drives are being more and more used in the industry and as result, it becomes important the availability of diagnostic tools that can perform a correct diagnostic of the drive operating status. Following this, the main objective of this research topic is to develop fault diagnostic methods for power converters in ac drives. The most important challenge is to develop algorithms that can be easily integrated into the main control system, having therefore low computational requirements. Furthermore, it is desired that the algorithm uses variables already available from the main control system in order to avoid the use of extra sensors. Important work was already done by the development of new algorithms for realtime fault diagnosis in power converters.

•

Development of fault-tolerant variable speed drives – Due to the widespread adoption of variable speed drives and thanks to their complexity, these energy conversion systems are very susceptible to suffer critical failures. This can be extremely undesired, especially for critical applications, where unplanned stoppages can result in very large costs or in even more catastrophic consequences. For these reasons, the development of fault-tolerant strategies applied to variable speed ac drive systems is mandatory. Considering this, it is intended in this research field to develop fault-tolerant drives applied to switched reluctance motors, permanent magnet synchronous motors and wind turbine power conversion systems using permanent magnet synchronous generators. In a first stage, the drive control system must be able to 294

ANNUAL REPORT 2010 – BASIC SCIENCES AND ENABLING TECHNOLOGIES

detect and identify power converter failures. Then, the system must be able to isolate the faulty device and proceed to hardware and software reconfigurations that allow the system operation, with possible limited conditions. Several simulations and experimental results were already obtained, showing the effectiveness of the developed strategies. •

Development of fault diagnostic methods for induction motors – Induction motors, currently, are very used in a wide range of industrial applications. For this reason, the availability of diagnostic methods for these specific electric machines can help to improve the reliability levels of a great number of applications and allow to drastically decrease the unintentional stoppages. In this context, the main objectives of this research is the development of diagnostic tools for induction motors concerning rotor broken bars, short-circuit faults and eccentricity faults. These methods must be effective when the machine is directly supplied by the grid and by a power converter in open-loop control. Research is also being done to detect rotor faults when the induction motor is fed by a power converter in closed-loop control.

•

Development of protection systems and diagnostic methods for fault detection in three-phase transformer windings – Power and distribution transformers have formed an essential part of electricity supply networks since the alternating current system was adopted more than a century ago. In general, transformer breakdowns are relatively few, but repair and

units

means

considerable

expenditure and time, and further, if faulted units are not cleared quickly and selectively can cause serious damage and power system stability problems. Protective schemes applied to transformers thus play a vital role in the economics and operation of a power system. Considering this, the main objective of this work is the development of protection systems and diagnostic methods for three-phase power transformers. The research is focused on detailed analysis and characterization of the transformer behavior under the influence of inrush currents and incipient winding faults such as turn-to-turn faults.

Telecommunications Power Supply Systems •

In this research field, it is intended to develop a prototype of an autonomous supplying system for telecommunication equipment based on renewable sources. The system should combine different renewable power sources such as wind generators and photovoltaic panels since, beyond their environmental advantages, they can represent a unlimited power source which fulfils the requirements for remote standalone telecommunication systems.

•

In an extension to the research topic mentioned in the previous topic, in a second stage, fault diagnostic methods for the different power converters that compose the entire system will be developed and tested. All the system modelling is being carried out using the MATALB/Simulink software and currently some parts of the experimental prototype, namely the photovoltaic panels, are being installed and tested.

Multi-level power converter topologies applied to electric motor drives – Multi-level power converters have gained a lot of interest for medium and high voltage applications and now they are starting to be used for low power and low voltage applications. This technology is based in the simple concept of connecting in series several power switches or power converters, allowing the use of semiconductors with less rated voltages. When applied to electric motor drives, among other advantages, they allow to achieve higher overall efficiency values. Considering this, it is under research the comparison of a typical two-level inverter and several multi-level inverter topologies in the performance of induction motor drives. Currently, all the system components are being modeled in MATLAB/Simulink for simulation. A detailed model of an induction motor is also under implementation in a finite element analysis software. Regarding the experimental setup, a lot of information is being collected in order to start to build a multi-level converter prototype.

•

Electric drives based on matrix converters – Recently, there has been an increasing interest in the development and use of electric drives based on matrix converters. Due to the advantages offered by the matrix converter, namely its inherent bidirectional power flow capability, 297

ANNUAL REPORT 2010 – BASIC SCIENCES AND ENABLING TECHNOLOGIES

associated with a controllable input power factor and sinusoidal input currents, it is expected that other areas of application such as aerospace and military will also embrace the use of this type of drive in a near future. Taking this into account, the main goal of this research area is the study of matrix converters applied to induction motors. A lot of work was done, namely the construction of a fully-functional matrix converter prototype. Fault diagnostic techniques were also developed for these specific power converters, leading to the publication of several papers.

Thermal Analysis of Induction Motors •

As far as both motor losses and temperature rise are concerned the supply conditions imposed by frequency converters, have introduced new problems. Additional losses in the iron, stator windings and rotor bars are among then. These losses are highly dependent on the inverter fundamental working frequency and on the harmonic content of both motor phase voltages and line currents. All these losses bring additional heating inside the motor that lead to motor temperature rising and the subsequent degradation of the windings insulation. Considering this, it is intended to develop finite element simulation models that can accurately 298

ANNUAL REPORT 2010 – BASIC SCIENCES AND ENABLING TECHNOLOGIES

model the temperature behavior of induction motors when supplied by power converters. Some work was already done in this field regarding the construction of the machine model. Experimental work is also carrying out in order to evaluate the machine temperature when it is supplied by an unbalanced system.

Maintenance Management os School Buildings •

This area of research concerns asset management of Portuguese Educational Facilities, namely infrastructure and fixed equipment. The Portuguese Educational System is a complex structure and, therefore, any suggestions to improve maintenance management must be based on the objective identification of those areas needing improvements, as the first step of an overall maintenance improvement process. The specificity of the several levels of education refers not only to pedagogical practices but also to spaces, installations and equipment policies management, human and material resources management, as well as financial and administrative management. The main goal is to develop theoretical models that typify maintenance management and organization of educational facilities, allowing the development of computational decision support tools for Maintenance management and organization.

Title

Flaw Imaging in Metals by Contactless Conductivity

Funding

FCT/PTDC

Descript.

The measuring principle is based on the phenomenon whereby the impedance of a coil generating a time-varying magnetic field changes in the presence of a conductive material as eddy currents are induced in the material. Therefore the idea of a contactless electrical conductivity imaging system (CECIS) is based on a sensor composed of two coils. One of the coils, designated the transmitter coil, is driven by an alternating current and generates an oscillating magnetic field that induces currents inside the object to be tested. These induced currents are related to the conductivity distribution of the body. Another coil, the receiver coil, measures the total magnetic field. One component of the magnetic field is related to the primary imposed currents and the other component is related to the induced eddy currents. As the signal originated from deeper voxel significantly attenuates before it reaches the receiving coil the information gets easily corrupted by measurement noise. By incorporating into the design a real time digital signal processor able to perform advanced signal processing techniques it is possible to increase significantly the range of the sensor. Two solutions are envisaged to accumulate data either by relocating the probe several times using a XY scanning mechanism or by using an array of sensors, i. e., several probes in the vicinity of the object to be tested. The mathematical basis of this methodology is developed in two parts. In the first part, the physics of the induction system is simulated in the forward problem either using a numerical method like the finite element method (FEM) or an artificial intelligent technique (ANN). The simulated system is used to preview the correspondence between first order variations in the secondary magnetic field to conductive perturbations in the conductive body. 305

ANNUAL REPORT 2010 – BASIC SCIENCES AND ENABLING TECHNOLOGIES

A set of equations in the discrete form can be formulated: Sx=b, where x is the unknown conductivity perturbation vector, b is the magnetic field measurement vector and S is the sensitivity matrix. The second part of this study is the formulation of the inverse relation of this correspondence in order to reconstruct the conductivity images for a three dimensional sample object: b=S x + y, where y represents unknown measurement noise present in the real scenario. Since the signal from a deeper voxel is smaller than

surface

voxel,

measurement

noise

corrupts

more

the

information from deeper voxels. However, the relation between the magnetic

measurements

and

the

conductivity

distribution

is

nonlinear. Thus, one way to estimate the solution is to linearize the forward problem around an initial conductivity distribution and update the conductivity distribution using a suitable algorithm by comparing the calculated fields with the measurements. Several algorithms can be used to minimize the norm of ||S x - b|| when solving for x. These algorithms must be investigated in order to select the one that provides the best performance for the problem to

be

evaluated.

The

mathematical

relation

between

the

conductivity distribution and the measurements is the backbone of the imaging algorithm.

economic, clean, and simple, one-pot procedure, where CO2 is both used as a solvent and as a reagent (C1 feedstock). To exclude dendrimers cytotoxicity and enhance their biodegradability urea linkages will be incorporated in the dendrimer architecture.Another interesting and cutting edge issue in dendrimer chemistry is that these nanometer-sized vehicles will be incorporated within layerbylayer (LBL) films using alternating hydrogen bond interactions as the driving force for assembly, thus enabling the incorporation of drugs and pH-sensitive release. The unique architectural features of dendrimers led to fairly recent developments in the field of chemical sensing. This almost unexplored potential opens-up for exciting opportunities that we will systematically explore: i) using the dendrimers library without end-capping for explosives detection ii) using perylene end-capped dendrimers for detection of metal cations.

The main objective of the LITES project is to prove in real life experimentation that intelligent street lighting using solid-state lights LED drastically reduces energy consumption. The lighting service delivered is compliant with road classes CE2-CE5, S- and A- according to the standard of EN13201 That means that our device can be installed in secondary street, commercial access, allotment, pedestrian way, cycle track. It is compliant with all electric standards for luminaires general requirements and tests as well. The core element of the solution is the dimming of the lamp depending on the environment; a set of embedded sensors measures ambient light, temperature, current, and detect motion. Output data of sensors is then processed by the embedded intelligence allowing optimum regulation of light levels. The members within the consortium have been carefully selected to cover the entire value-chain of the project and the standardisation as well. They are all convinced about the prosperous future for this technology, its significant energy saving potential up to 70 %, environmental and economical benefits and the increased level of traffic safety for the public.

based on matrix converters, with self-diagnostic and fault-tolerant capabilities. The drive, which will rely on the use of induction motors and PMSMs, will allow to detect and locate any fault in the matrix converter. After its detection, the control system of the drive will enter in a fault-tolerant operating mode, according to which the control strategy will be modified in order to minimize the consequences of the fault and thus maintaining the system running,

although

with

degraded

performance.

Besides

the

detection of faults in the matrix converter, and in the case of the induction motor drive, the integrated diagnostic system should also be able to detect faults in the motor, namely stator and rotor faults, bearing faults and airgap eccentricity. The drive obtained with these new features combines the advantages of the matrix converter with the high reliability granted by the integrated and fault-tolerant diagnostic/control system.

polymers by spin-coating Funding

FCT/PTDC

Descript.

This project deals with the optimization of organic electronic devices, namely photovoltaic cells (PV), light-emitting diodes (LEDs) and optical chemical sensors, through the provement of the organic film morphology and functionality using a low-cost, simple, and innovative method of patterning at the submicrometric or the nanoscale. Our group was recently pioneer in exploring a simple and low-cost method to prepare patterned films at the submicrometric scale using cross-linkable electroluminescent polymers also synthesised in our group. In principle, the method should be scalable to large substrates and to a broad range of different classes of conjugated polymers. Basically, it consists on controlling the phase separation occurring during the deposition of a solution containing a crosslinkable electro-active polymer and an «inert» polymer, on a substrate, by spin coating. The main original characteritsic of this approach

is

that

the

cross-linked

film

is

resistant

against

dissolution, enabling that multilayer devices may be fabricated utilizing low cost solution techniques. This project proposes i) to synthesise

new

cross-linkable

semiconducting

polymers

with

chemical properties designed for specific applications; ii) to extend and to explore the patterning method to those materials to obtain film morphologies tuned for specific applications iii) to fabricate efficient devices based on such films. The target devices are: - PV cells. Semiconducting polymer based-films where electrondonor and -acceptor materials are segregated forming vertical domains (relative to the electrodes) and these are separated from less than 20 nm represent the optimal film morphology, because it minimizes losses in the charge generation and transport to the electrodes

preparing

where

or

processes. We intend to functionalize the polymer nanopatterned film to recognise selectively a specific target molecule which acts as a fluorescence quencher, generating an optical sensor. Since nanostructures have a huge surface/volume ratio, an even higher sensitivity is expected. Examples of analytes to investigate are fluoride, cyanide, and iodide anions resultant from toxic gases, and metal ions such as Al3+, Pb 2+, and Ag+. - LEDs. The most efficient organic LEDs are based on multilayered devices comprising both charge transport layers and emissive layers

between

the

electrodes.

Besides

showing

reasonable

efficiencies, such values are still well below the predicted maxima. One approach for optimization, nearly unexplored so far, consists on the use of nanopatterned hole-transport layers to increase the contact area for charge transfer to the emissive layer. Also, there have been reports demonstrating higher emission efficiency in nanopatterned films, for which nanopatterning of the emissive layer represents another approach to optimize LEDs.

incorporation of acceptor molecules on the walls of mesoporous silica nanostructured materials and encapsulation of the donor polymers on the pores of those same silica materials. The key scientific objectives of the “SolarNHyMatâ€

project will be (i)

alignment of the acceptors (on the walls) and donors (on the pores), (ii) maximize the interfacial area and the donor:acceptor contact, (iii) isolation of the polymer chains into nanoscale domains leading to a confinement effect, (iv) charge stabilization conduction along individual chains with spontaneous formation of a graded-index waveguide, and (v) circumvent oxygen interference. The expected results for the “SolarNHyMatâ€

into account the above objectives are (i) avoid phase segregation and minimize the recombination process, (ii) improve charge separation and increase carrier’s mobility, (iii) no interchain hopping events would be required, (iv) improve gain and reduce loss, and (v) enhance the long term stability
