This book constitutes the joint refereed proceedings of the First International Workshop on Theory Building and Formal Methods in Electronic/Mobile Commerce, TheFormEMC, the first European Performance Engineering Workshop, EPEW, and the First International Workshop on Integration of Testing Methodologies, ITM, held jointly in association with FORTE 2004 in Toledo, Spain, in October 2004. The 27 revised full papers presented were carefully reviewed and selected from a total of 62 submissions. The papers are grouped in three topical sections corresponding to the workshop topics.

This book constitutes the refereed proceedings of the 17th IFIP TC 6/WG 6.1 International Conference on Testing Communicating Systems, TestCom 2005, held in Montreal, Canada in May/June 2005. The 24 revised full papers presented together with the extended abstract of a keynote talk were carefully reviewed and selected from initially 62 submissions. The papers address all current issues in testing communicating systems, ranging from classical telecommunication issues to general software testing.

This book covers the application of computational fluid dynamics from low-speed to high-speed flows, especially for use in aerospace applications.

Critical Infrastructure Protection II describes original research results and innovative applications in the interdisciplinary field of critical infrastructure protection. Also, it highlights the importance of weaving science, technology and policy in crafting sophisticated solutions that will help secure information, computer and network assets in the various critical infrastructure sectors. This book is the second volume in the annual series produced by the International Federation for Information Processing (IFIP) Working Group 11.10 on Critical Infrastructure Protection, an international community of scientists, engineers, practitioners and policy makers dedicated to advancing research, development and implementation efforts focused on infrastructure protection. The book contains a selection of twenty edited papers from the Second Annual IFIP WG 11.10 International Conference on Critical Infrastructure Protection held at George Mason University, Arlington, Virginia, USA in the spring of 2008.

Our life is dominated by hardware: a USB stick, the processor in our laptops or the SIM card in our smart phone. But who or what makes sure that these systems work stably, safely and securely from the word go? The computer - with a little help from humans. The overall name for this is CAD (computer-aided design), and it’s become hard to imagine our modern industrial world without it. So how can we be sure that the hardware and computer systems we use are reliable? By using formal methods: these are techniques and tools to calculate whether a system description is in itself consistent or whether requirements have been developed and implemented correctly. Or to put it another way: they can be used to check the safety and security of hardware and software. Just how this works in real life was also of interest at the annual conference on "Formal Methods in Computer-Aided Design (FMCAD)". Under the direction of Ruzica Piskac and Michael Whalen, the 21st Conference in October 2021 addressed the results of the latest research in the field of formal methods. A volume of conference proceedings with over 30 articles covering a wide range of formal methods has now been published for this online conference: starting from the verification of hardware, parallel and distributed systems as well as neuronal networks, right through to machine learning and decision-making procedures. This volume provides a fascinating insight into revolutionary methods, technologies, theoretical results and tools for formal logic in computer systems and system developments.
