This Festschrift is published in honor of Edward A. Lee, Robert S. Pepper Distinguished Professor Emeritus and Professor in the Graduate School in the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley, USA, on the occasion of his 60th birthday.The title of this Festschrift is "Principles of Modeling" because Edward A. Lee has long been devoted to research that centers on the role of models in science and engineering. He has been examining the use and limitations of models, their formal properties, their role in cognition and interplay with creativity, and their ability to represent reality and physics. The Festschrift contains 29 papers that feature the broad range of Edward A. Lee's research topics; such as embedded systems; real-time computing; computer architecture; modeling and simulation, and systems design.

This book constitutes the refereed proceedings of the 24th IFIP WG 6.1 International Conference on Coordination Models and Language, COORDINATION 2022, held in Lucca, Italy, in June 2022, as part of the 17th International Federated Conference on Distributed Computing Techniques, DisCoTec 2022. The 11 regular papers and one short paper presented in this book were carefully reviewed and selected from 22 submissions. COORDINATION provides a well-established forum for the growing community of researchers interested in coordination models and languages, architectures, verification and implementation techniques necessary to cope with the complexity induced by the demands of today's software development.

This book constitutes the refereed proceedings of the 15th International Conference on Software Architecture, ECSA 2021, held in Sweden, in September 2021. Due to the COVID-19 pandemic, the conference was held virtually. For the Research Track, 11 full papers, presented together with 5 short papers, were carefully reviewed and selected from 58 submissions. The papers are organized in topical sections as follows: architectures for reconfigurable and self-adaptive systems; machine learning for software architecture; architectural knowledge, decisions, and rationale; architecting for quality attributes; architecture-centric source code analysis; and experiences and learnings from industrial case studies.

This book constitutes the thoroughly refereed post-conference proceedings of the 7th International Conference on Fundamentals of Software Engineering, FSEN 2017, held in Tehran, Iran, in April 2017. The 16 full papers presented in this volume were carefully reviewed and selected from 49 submissions. The topics of interest in FSEN span over all aspects of formal methods, especially those related to advancing the application of formal methods in software industry and promoting their integration with practical engineering techniques.

This book constitutes the refereed proceedings of the 15th International Conference on Software Engineering and Formal Methods, SEFM 2017, held in Trento, Italy, in September 2017.

The present volume contains the proceedings of the Third IPM International Conference on Fundamentals of Software Engineering (FSEN), Kish, Iran, April 15-17, 2009. FSEN 2009 was organized by the School of Computer Science at the Institute for Studies in Fundamental Sciences (IPM) in Iran, in cooperation with the ACM SIGSOFT and IFIP WG 2.2. This conference brought together around 100 researchers and practitioners working on di?erent aspects of formal methods in software engineering from 15 di?erentcountries.ThetopicsofinterestinFSENspanoverallaspects offormal methods,especiallythoserelatedtoadvancingtheapplicationofformalmethods in software industry and promoting their integration with practical engineering techniques. The Program Committee of FSEN 2009 consisted of top researchers from 24 di?erent academic institutes in 11 countries. We received a total of 88 submissions from 25 countries out of which the Program Committee selected 22 as regular papers, 5 as short papers, and 7 as poster presentations in the conferenceprogram.Eachsubmissionwasreviewedbyatleastthreeindependent referees, for its quality, originality, contribution, clarity of presentation, and its relevance to the conference topics. This volume contains the revised versions of the regular and short papers presented at FSEN 2009. Three distinguished keynote speakers delivered their lectures at FSEN 2009 on models of computation: automata and processes (Jos Baeten), veri?cation, performanceanalysisandcontrollersynthesisforreal-timesystems(KimLarsen), and theory and tool for component-based model-driven development in rCOS (Zhiming Liu). Our invited speakers also contributed to this volume by s- mitting their keynote papers, which were accepted after they were reviewed by independent referees.
