This book addresses mechanisms for reducing model heterogeneity induced by the absence of explicit semantics expression in the formal techniques used to specify design models. More precisely, it highlights the advances in handling both implicit and explicit semantics in formal system developments, and discusses different contributions expressing different views and perceptions on the implicit and explicit semantics. The book is based on the discussions at the Shonan meeting on this topic held in 2016, and includes contributions from the participants summarising their perspectives on the problem and offering solutions. Divided into 5 parts: domain modelling, knowledge-based modelling, proof-based modelling, assurance cases, and refinement-based modelling, and offers inspiration for researchers and practitioners in the fields of formal methods, system and software engineering, domain knowledge modelling, requirement analysis, and explicit and implicit semantics of modelling languages.

This book constitutes the thoroughly refereed papers of the workshops held at the 8th International Conference on New Trends in Model and Data Engineering, MEDI 2018, in Marrakesh, Morocco, in October 2018. The 19 full and the one short workshop papers were carefully reviewed and selected from 50 submissions. The papers are organized according to the 4 workshops: International Workshop on Modeling, Verification and Testing of Dependable Critical Systems, DETECT 2018, Model and Data Engineering for Social Good Workshop, MEDI4SG 2018, Second International Workshop on Cybersecurity and Functional Safety in Cyber-Physical Systems, IWCFS 2018, International Workshop on Formal Model for Mastering Multifaceted Systems, REMEDY 2018.

This book constitutes the refereed proceedings of the 8h International Conference on Model and Data Engineering, MEDI 2018, held in Marrakesh, Morocco, in October 2018. The 23 full papers and 4 short papers presented together with 2 invited talks were carefully reviewed and selected from 86 submissions. The papers covered the recent and relevant topics in the areas of databases; ontology and model-driven engineering; data fusion, classsification and learning; communication and information technologies; safety and security; algorithms and text processing; and specification, verification and validation.

This book constitutes the refereed proceedings of the 18th International Symposium on Formal Methods, FM 2012, held in Paris, France, in August 2012. The 28 revised full papers presented together with 7 tool papers and 3 invited talks were carefully reviewed and selected from numerous submissions. The papers cover several aspects of formal methods, including verification, synthesis, runtime monitoring, testing and controller synthesis, as well as novel applications of formal methods in interesting domains such as satellites, autonomous vehicles and disease dynamics.

ThisvolumecontainstheproceedingsofIFM2010, the8thInternationalConf- ence on Integrated Formal Methods. The conference took place October 12-14, 2010, atthe INRIA researchcenterandthe LORIAlaboratoryinNancy, France. Previous editions were held in York, Dagstuhl, Turku, Canterbury, Eindhoven, Oxford, and Dusseldorf ] . The IFM conference series seeks to promote research into the combination of di?erent formal methods, including the combination of formal with semiformal methods, for system development. Such combinations are useful in order to apprehend di?erent aspects of systems, including fu- tional correctness, security, performance, and fault-tolerance. The conference provides a forum for discussing recent advances in the state of the art and for disseminating the results among the academic and industrial community. IFM2010received59submissions, coveringthespectrumofintegratedformal methods and ranging from formal and semiformal notations, semantics, re?- ment, veri?cation, and model transformations to type systems, logics, tools, and case studies. Each submission was reviewed by at least three members of the Program Committee. The committee decided to accept 20 papers. The conf- ence programalso included invited talks by Christel Baier, John Fitzgerald, and Rajeev Joshi. The conference was preceded by a day dedicated to the Wo- shop on Formal Methods for Web Data Trust and Security (WTS 2010)and two tutorials, one on the veri?cation of C# programs using Spec# and Boogie 2, + by Rosemary Monahan, and the other on the TLA proof system, by Denis Cousineau and Stephan Mer

This book constitutes the proceedings of the 8th International Conference on Rigorous State-Based Methods, ABZ 2021, which was planned to take place in Ulm, Germany, during June 6-11, 2021. The conference changed to an online format due to the COVID-19 pandemic. The 6 full and 8 short papers included in this volume were carefully reviewed and selected from 18 submissions. The proceedings also include 3 PhD symposium contributions. They deal with state-based and machine-based formal methods, mainly Abstract State Machines (ASM), Alloy, B, TLA+, VDM, and Z.

This book constitutes the refereed proceedings of the 7th International Conference on Rigorous State-Based Methods, ABZ 2020, which was due to be held in Ulm, Germany, in May 2020. The conference was cancelled due to the COVID-19 pandemic. The 12 full papers and 9 short papers were carefully reviewed and selected from 61 submissions. They are presented in this volume together with 2 invited papers, 6 PhD-Symposium-contributions, as well as the case study and 6 accepted papers outlining solutions to it. The papers are organized in the following sections: keynotes and invited papers; regular research articles; short articles; articles contributing to the case study; short articles of the PhD-symposium (work in progress).

This book constitutes the refereed proceedings of the 11th International Colloquium on Theoretical Aspects of Computing, ICTAC 2014 held in Bucharest, Romania, in September 2014. The 25 revised full papers presented together with three invited talks were carefully reviewed and selected from 74 submissions. The papers cover various topics such as automata theory and formal languages; principles and semantics of programming languages; theories of concurrency, mobility and reconfiguration; logics and their applications; software architectures and their models, refinement and verification; relationship between software requirements, models and code; static and dynamic program analysis and verification; software specification, refinement, verification and testing; model checking and theorem proving; models of object and component systems; coordination and feature interaction; integration of theories, formal methods and tools for engineering computing systems; service-oriented architectures: models and development methods; models of concurrency, security, and mobility; theories of distributed, grid and cloud computing; real-time, embedded, hybrid and cyber-physical systems; type and category theory in computer science; models for e-learning and education; case studies, theories, tools and experiments of verified systems; domain-specific modeling and technology: examples, frameworks and practical experience; challenges and foundations in environmental modeling and monitoring, healthcare, and disaster management.
