This volume contains the 37 papers presented at the 9th International Con- rence on Real-Time and Embedded Computing Systems and Applications (RT- CSA 2003). RTCSA is an international conference organized for scientists and researchers from both academia and industry to hold intensive discussions on advancing technologies topics on real-time systems, embedded systems, ubiq- tous/pervasive computing, and related topics. RTCSA 2003 was held at the Department of Electrical Engineering of National Cheng Kung University in Taiwan. Paper submissions were well distributed over the various aspects of real-time computing and embedded system technologies. There were more than 100 participants from all over the world. The papers, including 28 regular papers and 9 short papers are grouped into thecategoriesofscheduling,networkingandcommunication,embeddedsystems, pervasive/ubiquitous computing, systems and architectures, resource mana- ment, ?le systems and databases, performance analysis, and tools and de- lopment. The grouping is basically in accordance with the conference program. Earlier versions of these papers were published in the conference proceedings. However, some papers in this volume have been modi?ed or improved by the authors, in various aspects, based on comments and feedback received at the conference. It is our sincere hope that researchers and developers will bene?t from these papers. We would like to thank all the authors of the papers for their contribution. We thank the members of the program committee and the reviewers for their excellent work in evaluating the submissions. We are also very grateful to all the members of the organizing committees for their help, guidance and support.

This thesis addresses optimal control of discrete-time switched linear systems with application to networked embedded control systems (NECSs). Part I focuses on optimal control and scheduling of discrete-time switched linear systems. The objective is to simultaneously design a control law and a switching (scheduling) law such that a cost function is minimized. This optimization problem exhibits exponential complexity. Taming the complexity is a major challenge. Two novel methods are presented to approach this optimization problem: Receding-horizon control and scheduling relies on the receding horizon principle. The optimization problem is solved based on relaxed dynamic programming, allowing to reduce complexity by relaxing optimality within predefined bounds. The solution can be expressed as a piecewise linear (PWL) state feedback control law. Stability is addressed via an a priori stability condition based on a terminal weighting matrix and several a posteriori stability criteria based on constructing piecewise quadratic Lyapunov functions and on utilizing the cost function as a candidate Lyapunov function. Moreover, a region-reachability criterion is derived. Periodic control and scheduling relies on periodic control theory. Both offline and online scheduling are studied. The optimization problem is solved based on periodic control and exhaustive search. The online scheduling solution can again be expressed as a PWL state feedback control law. Stability is guaranteed inherently. Several methods are proposed to reduce the online complexity based on relaxation and heuristics. Part II focuses on optimal control and scheduling of NECSs. The NECS is modeled as a block-diagonal discrete-time switched linear system. Various control and scheduling codesign strategies are derived based on the methods from Part I regarding the structural properties of NECSs. The methods presented in Part I and II are finally evaluated in a case study.

Welcome to the proceedings of the 2005 International Conference on Emb- ded Software and Systems (ICESS 2005) held in Xian, China, December 16-18, 2005. With the advent of VLSI system level integration and system-on-chip, the center of gravity of the computer industry is now moving from personal c- puting into embedded computing. Embedded software and systems are incre- ingly becoming a key technological component of all kinds of complex technical systems, ranging from vehicles, telephones, aircraft, toys, security systems, to medical diagnostics, weapons, pacemakers, climate control systems, etc. The ICESS 2005 conference provided a premier international forum for - searchers, developers and providers from academia and industry to address all resulting profound challenges; to present and discuss their new ideas, - search results, applications and experience; to improve international com- nication and cooperation; and to promote embedded software and system - dustrialization and wide applications on all aspects of embedded software and systems.

The 14th International Conference on Principles of Distributed Systems (OPODIS 2010) took place during December 14–17, 2010 in Tozeur, Tunisia. It continued a tradition of successful conferences; Chantilly (1997), Amiens (1998), Hanoi (1999), Paris (2000), Mexico (2001), Reims (2002), La Martinique (2003), Gre- ble (2004), Pisa (2005), Bordeaux (2006), Guadeloupe (2007), Luxor (2008) and Nˆ?mes (2009). The OPODIS conference constitutes an open forum for the exchange of sta- of-the-art knowledge on distributed computing and systems among researchers from around the world. Following the tradition of the previous events, the p- gram was composed of high-quality contributed papers. The program call for papers looked for original and signi?cant research contributions to the theory, speci?cation, design and implementation of distributed systems, including: – Communication and synchronization protocols – Distributed algorithms, multiprocessor algorithms – Distributed cooperative computing – Embedded systems – Fault-tolerance, reliability, availability – Grid and cluster computing – Location- and context-aware systems – Mobile agents and autonomous robots – Mobile computing and networks – Peer-to-peer systems, overlay networks – Complexity and lower bounds – Performance analysis of distributed systems – Real-time systems – Security issues in distributed computing and systems – Sensor networks: theory and practice – Speci?cation and veri?cation of distributed systems – Testing and experimentation with distributed systems In response to this call for papers, 122 papers were submitted. Each paper was reviewed by at least three reviewers, and judged according to scienti?c and p- sentation quality, originality and relevance to the conference topics.

This book constitutes the refereed proceedings of the 17th Ada-Europe International Conference on Reliable Software Technologies, Ada-Europe 2012, held in Stockholm, Sweden, in June 2012. The revised 15 full papers presented were carefully reviewed and selected from 34 submissions. They are organized in topical sections on application frameworks, use of ada, modeling, testing and validation,and real-time systems.
