This book constitutes the refereed proceedings of the 18th International Symposium Fundamentals of Computation Theory, FCT 2011, held in Oslo, Norway, in August 2011. The 28 revised full papers presented were carefully reviewed and selected from 78 submissions. FCT 2011 focused on algorithms, formal methods, and emerging fields, such as ad hoc, dynamic and evolving systems; algorithmic game theory; computational biology; foundations of cloud computing and ubiquitous systems; and quantum computation.

This volume contains the proceedings of FMOODS2005, the 7th IFIPWG6. 1 International Conference on Formal Methods for Open Object-Based Distributed Systems. The conference was held in Athens, Greece on June 15-17, 2005.

ThegoaloftheFMOODSseriesofconferencesistobringtogetherresearchers whose work encompasses three important and related ?elds: - formal methods; - distributed systems; - object-based technology. Sucha convergenceis representativeofrecentadvancesin the?eld ofdistributed systems, and provides links between several scienti?c and technological com- nities, as represented by the conferences FORTE, CONCUR, and ECOOP. The objective of FMOODS is to provide an integrated forum for the pres- tation of research in the above-mentioned ?elds, and the exchange of ideas and experiences in the topics concerned with the formal methods support for open object-based distributed systems. For the call for papers, aspects of interest - cluded, but were not limited to: formal models; formal techniques for speci?- tion, design, or analysis; veri?cation, testing, and validation; component-based design; formal aspects of service-oriented computing; semantics and type s- tems for programming, coordination, or modelling languages; behavioraltyping; multiple viewpoint modelling and consistency between di?erent models; tra- formations of models; integration of quality-of-service requirements into formal models; formal models for security; formal approachesto distributed component frameworks;andapplications andexperience, carefullydescribed. Work onthese aspects of (o?cial and de facto) standardnotation and languagesfor serviceo- ented design, e. g. web services orchestration languages, was explicitly welc

The volume LNCS 12226 constitutes the revised selected papers from the four workshops collocated with the 17th International Conference on Software Engineering and Formal Methods, SEFM 2019. The 13 full papers presented together with 7 short papers in this volume were carefully reviewed and selected from a total of 45 submissions. They stem from the following workshops: CoSim-CPS 2019 - 3rd International Workshop on Formal Co-Simulation of Cyber-Physical Systems; ASYDE 2019 -- 1st International Workshop on Cognition: Interdisciplinary Foundations, Models and Applications; and FOCLASA 2019 -- 17th International Workshop on Foundations of Coordination Languages and Self-Adaptive Systems .

Why would you read this preface? As we start thinking what to write here, we wonder who is going to read these words. Fromourperspective-thatofwritersaddressinganaudienceofreaders-you are most likely Willem-Paul de Roever. Willem: our main motivation in putting together this Festschrift is to honor you on the occasion of your retirement. In terms of scienti?c ancestry, you are a father to two of us, and a grandfather to 1 the third , and you have had a profound impact on our formation as computer scientists.Atthepersonallevel,weknowyouasakind-hearted,generousperson. We are grateful to know you in these ways, and hope to have encounters with you in many years to come. AnotherlikelypossibilityisthatyouareCorinneorJojanneke,wifeordau- ter of Willem; the two strong pillars on which so much in his life is founded. You share the honor,respect, and love that went into the writing, as will be ackno- edged by those contributing authors that know you - which are almost all. Also, we would like to thank you for your help in sending us photographs for inclusion in this book, and for your encouragement. The next option is that you are one of the contributing authors. In this case you may wonder why it took us so long to get this work published. After all, wasn'tit"almostdone"alreadyattheretirementeventinJuly2008?Theanswer is twofold: we gave everyone ample time to revise their submissions in line with the recommendations by the referees; and we ourselves took ample time to put everything together. Our hope is that this will be visible in the quality of the ?nal result.
