This book constitutes the refereed proceedings of the 27th IFIP WG 6.1 International Conference on Formal Techniques for Networked and Distributed Systems, FORTE 2007, held in Tallinn, Estonia, in September 2007 co-located with TestCom/FATES 2007.

The 22 revised full papers presented together with 1 invited talk were carefully reviewed and selected from 67 submissions. The papers focus on service oriented computing and architectures using formalized and verified approaches. In addition to the classical protocol specification and verification problems, the issues of composition of protocol functions and of algorithms for distributed systems are addressed. The papers are organized in topical sections on message sequence charts and SDL, concurrency, model programs, theory, verification, model checking, requirements and QoS, as well as components.

This book constitutes the thoroughly refereed papers of the workshops held at the 10th International Conference on New Trends in Model and Data Engineering, MEDI 2021, held in Tallinn, Estonia, in June 2021: Workshop on moDeling, vErification and Testing of dEpendable CriTical systems, DETECT 2021; Symposium on Intelligent and Autonomous Systems, SIAS 2021; Worjshop on Control Software: Methods, Models, and Languages, CSMML 2021; Blockchain for Inter-Organizational Collaboration, BIOC 2021; The International Health Data Workshop, HEDA 2021. The 20 full and the 4 short workshop papers presented were carefully reviewed and selected from 61 submissions. The papers are organized according to the workshops: Workshop on moDeling, vErification and Testing of dEpendable CriTical systems, DETECT 2021; Symposium on Intelligent and Autonomous Systems, SIAS 2021; Worjshop on Control Software: Methods, Models, and Languages, CSMML 2021; Blockchain for Inter-Organizational Collaboration, BIOC 2021; The International Health Data Workshop, HEDA 2021.

System Assurances: Modeling and Management updates on system assurance and performance methods using advanced analytics and understanding of software reliability growth modeling from today's debugging team's point-of-view, along with information on preventive and predictive maintenance and the efficient use of testing resources. The book presents the rapidly growing application areas of systems and software modeling, including intelligent synthetic characters, human-machine interface, menu generators, user acceptance analysis, picture archiving and software systems. Students, research scholars, academicians, scientists and industry practitioners will benefit from the book as it provides better insights into modern related global trends, issues and practices.
