PrefaceThis year the 13th WSEAS International Conference on COMPUTERS was held in Rodos,Greece, in July 23-25, 2009. The Conference remains faithful to its original idea of providing aplatform to discuss artificial intelligence, computer networking, computer science education,hardware and architecture, multimedia, operating, networked and storage systems, wirelesssensor networks, programming languages, hardware engineering, tele-medicine and medicalinformatics, tele-healthcare, algorithms and multiplexity etc. with participants from all over theworld, both from academia and from industry.Its success is reflected in the papers received, with participants coming from several countries,allowing a real multinational multicultural exchange of experiences and ideas.The accepted papers of this conference are published in this Book that will be indexed by ISI.Please, check it: www.worldses.org/indexes as well as in the CD-ROM Proceedings. They willbe also available in the E-Library of the WSEAS. The best papers will be also promoted in manyJournals for further evaluation.A Conference such as this can only succeed as a team effort, so the Editors want to thank theInternational Scientific Committee and the Reviewers for their excellent work in reviewing thepapers as well as their invaluable input and advice.The Editors

Proceedings of the 13th WSEAS International Conference on COMPUTERSKeynote Lecture 1Embedded Systems Design – Scientific Challenges and Work DirectionsProfessor Joseph SifakisVerimag & ARTIST2 NoECentre Equation2 avenue de Vignate38610 GIERES, FRANCEE-mail: Joseph.Sifakis@imag.frAbstract: The development of a satisfactory Embedded Systems Design Science provides a timely challenge andopportunity for reinvigorating Computer Science. Embedded systems are components integrating software andhardware jointly and specifically designed to provide given functionalities, which are often critical. They are used inmany applications areas including transport, consumer electronics and electrical appliances, energy distribution,manufacturing systems, etc. Embedded systems design requires techniques taking into account extra-functionalrequirements regarding optimal use of resources such as time, memory and energy while ensuring autonomy,reactivity and robustness. Jointly taking into account these requirements raises a grand scientific and technicalchallenge: extending Computer Science with paradigms and methods from Control Theory and ElectricalEngineering. Computer Science is based on discrete computation models not encompassing physical time andresources which are by their nature very different from analytic models used by other engineering disciplines.We summarize some current trends in embedded systems design and point out some of their characteristics, such asthe chasm between analytical and computational models, and the gap between safety critical and best-effortengineering practices. We call for a coherent scientific foundation for embedded systems design, and we discuss afew key demands on such a foundation: the need for encompassing several manifestations of heterogeneity, and theneed for design paradigms ensuring constructivity and adaptivity.We discuss main aspects of this challenge and associated research directions for different areas such as modeling,programming, compilers, operating systems and networks.Brief Biography of the Speaker: Joseph Sifakis is a CNRS researcher and the founder of Verimag laboratory(http://www-verimag.imag.fr/), in Grenoble, France. He holds the INRIA-Schneider endowed industrial chair sinceSeptember 1st 2008. He studied Electrical Engineering at the Technical University of Athens and Computer Scienceat the University of Grenoble. Verimag is a leading research laboratory in the area of critical embedded systems. Itdeveloped the underlying theory and technology for the SCADE tool, used by Airbus for the design and validation ofits critical real-time systems, and is becoming a de facto standard for aeronautics. Verimag has a lasting and strategiccollaboration with ST Microelectronics, France Telecom R&D, and Airbus, through which numerous results onvalidation and testing have been transferred. Joseph Sifakis is recognized for his pioneering work on both theoreticaland practical aspects of Concurrent Systems Specification and Verification. He contributed to emergence of the areaof model-checking, currently the most widely-used method for the verification of industrial applications. His currentresearch activities include component-based design, modeling, and analysis of real-time systems with focus oncorrect-by-construction techniques (http://www-verimag.imag.fr/ sifakis/). Joseph Sifakis has broad experience withindustry, notably though joint projects with partners such as Astrium, the European Space Agency, France Telecom,ST Microelectronics and he has also been active for many years in consulting. Joseph Sifakis is the ScientificCoordinator of the European Network of Excellence ARTIST2 on Embedded Systems Design. (http://www.artistembedded.org/). This network gathers 35 of the best European teams in the area, and aims to produce innovativeresults for cost-effective design of dependable embedded systems. It will also promote innovative methods safe andsecure systems, notably through cooperation with key European industrial partners such as Thales, Airbus, Ericsson,Philips, and ST Microelectronics. Joseph Sifakis is the director of the CARNOT Institute "Intelligent Software andSystems" in Grenoble (http://www.carnot-lsi.com/). Joseph Sifakis is a member of the editorial board of severaljournals, co-founder of the Internatio
