This book provides an in-depth description of event-based systems, covering topics ranging from local event matching and distributed event forwarding algorithms, through a practical discussion of software engineering issues raised by the event-based style, to state-of-the-art research in event-based systems like composite event detection and security. The authors offer a comprehensive overview, and show the power of event-based architectures in modern system design, encouraging professionals to exploit this technique in next generation large-scale distributed applications like information dissemination, network monitoring, enterprise application integration, or mobile systems.

This two-volume set LNCS 3290/3291 constitutes the refereed proceedings of the three confederated conferences CoopIS 2004, DOA 2004, and ODBASE 2004 held as OTM 2004 in Agia Napa, Cyprus in October 2004. The 94 revised full papers presented were carefully reviewed and selected from a total of 380 submissions. In accordance with the three OTM 2004 main conferences CoopIS, DOA, and ODBASE, the papers are devoted to interoperability, workflow, and cooperation; distributed objects, infrastructure and enabling technology, and Internet computing; and data and Web semantics.

This book constitutes the refereed proceedings of the 9th International Conference on High-Performance Computing and Networking, HPCN Europe 2001, held in Amsterdam, The Netherlands in June 2001. The 67 revised papers and 15 posters presented were carefully reviewed and selected from a total of almost 200 submissions. Among the areas covered are Web/grid applications of HPCN, end user applications, computational science, computer science, and Java in HPCN.

The near future will see the increased use of parallel computing technologies at all levels of mainstream computing. Computer hardware increasingly employs parallel techniques to improve computing power for the solution of large scale and computer intensive applications. Cluster and grid technologies make possible high speed computing facilities at vastly reduced costs.These developments can be expected to result in the extended use of all types of parallel computers in virtually all areas of human endeavour. Computer intensive problems in emerging areas such as financial modelling, data mining and multimedia systems, in addition to traditional application areas of parallel computing such as scientific computing and simulation, will lead to further progress. Parallel computing as a field of scientific research and development has already become one of the fundamental computing technologies.This book gives an overview of new developments in parallel computing at the start of the 21st century, as well as a perspective on future developments.

The Sixth International Conference on Reliable Software Technologies, Ada- Europe 2001, took place in Leuven, Belgium, May 14-18, 2001. It was sponsored by Ada-Europe, the European federation of national Ada societies, in cooperation with ACM SIGAda, and it was organized by members of the K.U. Leuven and Ada- Belgium. This was the 21st consecutive year of Ada-Europe conferences and the sixth year of the conference focusing on the area of reliable software technologies. The use of software components in embedded systems is almost ubiquitous: planes fly by wire, train signalling systems are now computer based, mobile phones are digital devices, and biological, chemical, and manufacturing plants are controlled by software, to name only a few examples. Also other, non-embedded, mission-critical systems depend more and more upon software. For these products and processes, reliability is a key success factor, and often a safety-critical hard requirement. It is well known and has often been experienced that quality cannot be added to software as a mere afterthought. This also holds for reliability. Moreover, the reliability of a system is not due to and cannot be built upon a single technology. A wide range of approaches is needed, the most difficult issue being their purposeful integration. Goals of reliability must be precisely defined and included in the requirements, the development process must be controlled to achieve these goals, and sound development methods must be used to fulfill these non-functional requirements.
