The Ninth International Conference on Reliable Software Technologies, Ada- Europe 2004, took place in Palma, Spain, June 14–18, 2004. It was sponsored by Ada-Europe, the European federation of national Ada societies, and Ada- Spain, in cooperation with ACM SIGAda. It was organized by members of the University of the Balearic Islands (UIB). As in past years, the conference comprised a three-day technical program, during which the papers contained in these proceedings were presented, along with vendor presentations. The technical program was bracketed by two tutorial days, when the attendees had the opportunity to catch up on a variety of topics related to the ?eld, at both introductory and advanced levels. Furthermore, the conference was accompanied by an exhibition where vendors presented their products for supporting reliable-software development.

This book constitutes the refereed proceedings of the international Joint Modular Languages Conference, JMLC 2003, held in Klagenfurt, Austria in August 2003. The 17 revised full papers and 10 revised short papers presented together with 5 invited contributions were carefully reviewed and selected from 47 submissions. The papers are organized in topical sections on architectural concepts and education, component architectures, language concepts, frameworks and design principles, compilers and tools, and formal aspects and reflective programming.

Real-time and embedded systems are essential to our lives, from controlling car engines and regulating traffic lights to monitoring plane takeoffs and landings to providing up-to-the-minute stock quotes. Bringing together researchers from both academia and industry, the Handbook of Real-Time and Embedded Systems provides comprehensive covera

WORDS 2003 Fall focuses on the technology that enables the realization of object-oriented real-time computing systems and the dependability and quality-of-service (QoS) aspects. The interest in this technology continues to quickly grow due to its applicability to a wide range of computing systems, from complex real-time systems to distributed embedded systems. The papers in WORDS 2003F cover the various areas related to the foundation and applications of object-oriented real-time computing systems.
