This book constitutes the refereed proceedings of the 21th IFIP WG 6.1 International Conference on Testing Communicating Systems, TESTCOM 2009, and the 9th International Workshop on Formal Approaches to Testing of Software, FATES 2009, jointly held in Eindhoven, The Netherlands, in November 2009. The 13 revised full papers presented together with 6 short papers were carefully selected from 37 submissions to both events. The papers cover new approaches, concepts, theories, methodologies, tools, and experiences in the field of testing of communicating systems and general software.

This book constitutes the refereed proceedings of the 19th IFIP TC 6/WG 6.1 International Conference on Testing Communicating Systems, TestCom 2007, and the 7th International Workshop on Formal Approaches to Testing of Software, FATES 2007, held in Tallinn, Estonia. It covers all current issues in testing communicating systems and formal approaches in testing of software, from classical telecommunication issues to general software testing.

This volume contains the proceedings of the 16th IFIP TC6/WG6.1 Inter- tional Conference on Testing of Communicating Systems (TestCom 2004). This conference was held at St Anne's College, Oxford, UK, from March 17 to March 19, 2004. TestCom 2004 was the sixteenth in a series of IFIP-sponsored events that started in 1988. The previous events were held in Vancouver, Canada (1988); B- lin, Germany (1989); McLean, USA (1990); Leidschendam, Netherlands (1991); Montreal, Canada (1992); Pau, France (1993); Tokyo, Japan (1994); Evry, France (1995); Darmstadt, Germany (1996); Cheju Island, Korea (1997); Tomsk, R- sia (1998); Budapest, Hungary (1999); Ottawa, Canada (2000); Berlin, Germany (2002); and Sophia Antipolis, France (2003). TestCom was not held in 2001 since at this point the conference moved from autumn to spring. TestCom 2004 was organized by Brunel University, UK and LSR-IMAG, France and was sponsored by IFIP. Support was also provided by the Engineering and Physical Sciences Research Council (EPSRC). We are grateful to the keynote speaker, Prof. Sir Tony Hoare, FRS, and our invited speakers for agreeing to address TestCom 2004.

This book constitutes the refereed proceedings of the 27th IFIP WG 6.1 International Conference on Testing Software and Systems, ICTSS 2015, held in Sharjah and Dubai, United Arab Emirates, in November 2015. The 14 revised full papers and 4 short papers presented were carefully reviewed and selected from 42 submissions. The papers are organized in topical sections on model based testing, test derivation methods, monitoring and fault localization, model and system testing, and real-time systems.

This book constitutes the refereed proceedings of the 23rd IFIP WG 6.1 International Conference on Testing Software and Systems, ICTSS 2011, held in Paris, France, in November 2011. The 13 revised full papers presented together with 2 invited talks were carefully selected from 40 submissions. The papers address the conceptual, theoretic, and practical problems of testing software systems, including communication protocols, services, distributed platforms, middleware, controllers, and security infrastructures.

This book features selected papers presented at the Fifth International Conference on Nanoelectronics, Circuits and Communication Systems (NCCS 2019). It covers a range of topics, including nanoelectronic devices, microelectronics devices, material science, machine learning, Internet of things, cloud computing, computing systems, wireless communication systems, advances in communication 5G and beyond. Further, it discusses VLSI circuits and systems, MEMS, IC design and testing, electronic system design and manufacturing, speech signal processing, digital signal processing, FPGA-based wireless communication systems and FPGA-based system design, Industry 4.0, e-farming, semiconductor memories, and IC fault detection and correction.

This book constitutes the refereed proceedings of the 18th IFIP TC 6/WG 6.1 International Conference on Testing Communicating Systems, TestCom 2006. The 23 revised full papers presented were carefully reviewed and selected from initially 48 submissions. The papers address all current issues in testing communicating systems, ranging from classical telecommunication issues to general software testing.

Embedded systems now include a very large proportion of the advanced products designed in the world, spanning transport (avionics, space, automotive, trains), electrical and electronic appliances (cameras, toys, televisions, home appliances, audio systems, and cellular phones), process control (energy production and distribution, factory automation and optimization), telecommunications (satellites, mobile phones and telecom networks), and security (e-commerce, smart cards), etc. The extensive and increasing use of embedded systems and their integration in everyday products marks a significant evolution in information science and technology. We expect that within a short timeframe embedded systems will be a part of nearly all equipment designed or manufactured in Europe, the USA, and Asia. There is now a strategic shift in emphasis for embedded systems designers: from simply achieving feasibility, to achieving optimality. Optimal design of embedded systems means targeting a given market segment at the lowest cost and delivery time possible. Optimality implies seamless integration with the physical and electronic environment while respecting real-world constraints such as hard deadlines, reliability, availability, robustness, power consumption, and cost. In our view, optimality can only be achieved through the emergence of embedded systems as a discipline in its own right.
