Formal methods have been established as the rigorous engineering methodology for the system development. Applying formal methods to a large and complex system development often requires the modelling of different aspects of such a system. For instance, complex systems (such as integrated avionics systems, engine control software) can involve functional and timing requirements that must be eventually implemented as executing code on a communicating distributed topology. This book contains the papers presented at the First International Workshop on Integrated Formal Methods, held at the University of York in June 1999. The conference provided a forum for the discussion of theoretical aspects of combing behavioural and state-based formalisms and practical solutions to the industrial problems of this approach.

This volume contains the proceedings of ICTAC 2004, the 1st International Colloquium on Theoretical Aspects of Computing, which was held in Guiyang, China on 20-24 September 2004. ICTAC was founded by the International Institute for Software Technology of the United Nations University (UNU-IIST). Its aim is to bring together pr- titioners and researchers from academia, industry, and government to present research results, and exchange experience, ideas, and solutions for their pr- lems in theoretical aspects of computing. The geographic focus of the ICTAC events is on developing countries to help to strengthen them in their research, teaching, and development in computer science and engineering, to encourage research cooperation among developing countries, and to improve the links - tween developing countries and industrial countries. The Program Committee of ICTAC 2004 received 111 submissions from over 30 countries and regions. Each paper was reviewed, mostly by at least three r- ereesworkinginrelevant?elds,butbytwoinafewcases.Borderlinepaperswere further discussed during an online meeting of the Program Committee.Thir- fourpaperswereacceptedbasedonoriginality,technicalsoundness,presentation andrelevancetosoftwareengineeringandformalmethods.Wesincerelythankall the authors who submitted their work for consideration.

ThisvolumecontainstheproceedingsofFM2003,the12thInternationalFormal Methods Europe Symposium which was held in Pisa, Italy on September 8–14, 2003. Formal Methods Europe (FME, www. fmeurope. org) is an independent - sociation which aims to stimulate the use of and research on formal methods for system development. FME conferences began with a VDM Europe symposium in 1987. Since then, the meetings have grown and have been held about once - ery 18 months. Throughout the years the symposia have been notably successful in bringing together researchers, tool developers, vendors, and users, both from academia and from industry. Unlike previous symposia in the series, FM 2003 was not given a speci?c theme. Rather, its main goal could be synthesized as “widening the scope. ” Indeed, the organizers aimed at enlarging the audience and impact of the symposium along several directions. Dropping the su?x ‘E’ from the title of the conference re?ects the wish to welcome participation and contribution from every country; also,contributionsfromoutsidethetraditionalFormalMethodscommunitywere solicited. The recent innovation of including an Industrial Day as an important part of the symposium shows the strong commitment to involve industrial p- ple more and more within the Formal Methods community. Even the traditional and rather fuzzy borderline between “software engineering formal methods” and methods and formalisms exploited in di?erent ?elds of engineering was so- what challenged.

This book constitutes the refereed proceedings of the International Symposium on High Performance Computing, ISHPC '97, held in Fukuoka, Japan in November 1997.The volume presents four distinguished papers and 16 revised regular papers selected from more than 40 submissions on the basis of at least three peer reviews. Also included are seven invited contributions by leading authorities and 10 selected poster presentations. The papers are organized in topical chapters on high performance systems architectures, networks, compilers, systems software, and applications in various areas.

Formal engineering methods are intended to o?er e?ective means for integ- tion of formal methods and practical software development technologies in the context of software engineering. Their purpose is to provide e?ective, rigorous, and systematic techniques for signi?cant improvement of software productivity, quality, and tool supportability. In comparison with formal methods, a distinct feature of formal engineering methods is that they emphasize the importance of the balance between the qualities of simplicity, visualization, and preciseness for practicality. To achieve this goal, formal engineering methods must be - veloped on the basis of both formal methods and existing software technologies in software engineering, and they must serve the improvement of the softwa- engineering process. ICFEM 2008 marks the tenth anniversary of the ?rst ICFEM conference, which was held in Hiroshima in 1997. It aims to bring together researchers and practitioners who are interested in the development and application of formal engineering methods to present their latest work and discuss future research directions. The conference o?ers a great opportunity for researchers in both formal methods and software engineering to exchange their ideas, experience, expectation and to ?nd out whether and how their research results can help advance the state of the art.
