This book constitutes the refereed proceedings of the 10th International Conference on Formal Modeling and Analysis of Timed Systems, FORMATS 2012, held in London, UK in September 2012. The 16 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 34 submissions. The book covers topics of foundations and semantics, methods and tools, techniques, algorithms, hybrid automata, appilcations, real-time software and hardware circuits.

This book constitutes the refereed proceedings of the 20th International Conference on Runtime Verification, RV 2020, held in Los Angeles, CA, USA, in October 2020. The conference was held virtually due to the COVID-19 pandemic. The 14 regular papers and 2 short papers presented in this book were carefully reviewed and selected from 43 submissions. Also included are an invited paper, 5 tutorial papers, 6 tool papers, and a benchmark paper. The RV conference is concerned with all aspects of monitoring and analysis of hardware, software and more general system executions. The papers are organized in the following topical sections: runtime verification for autonomy; runtime verification for software; runtime verification with temporal logic specifications; stream-based monitoring; and runtime verification for cyber-physical systems.

This book constitutes the proceedings of the 25th International Workshop on Formal Methods for Industrial Critical Systems, FMICS 2020, which was held during September 2-3, 2020. The conference was planned to take place in Vienna, Austria. Due to the COVID-19 pandemic it changed to a virtual event.The 11 full papers presented in this volume were carefully reviewed and selected from 26 submissions. The papers are organized in topical sections as follows: Quantitative Analysis and Cyber-Physical Systems, Formal Verification of Industrial Systems, Temporal Logic and Model Checking. The book also contains a lengthy report on a Formal Methods Survey conducted on occasion of the 25th edition of the conference.

Recently, contract-based design has been proposed as an orthogonal approach that complements system design methodologies proposed so far to cope with the complexity of system design. Contract-based design provides a rigorous scaffolding for verification, analysis, abstraction/refinement, and even synthesis. Several results have been obtained in this domain but a unified treatment of the topic that can help put contract-based design in perspective has been missing. Contracts for System Design provides such a treatment where contracts are precisely defined and characterized so that they can be used in design methodologies with no ambiguity. It identifies the essence of complex system design using contracts through a mathematical meta-theory, where all the properties of the methodology are derived from a very abstract and generic notion of contract. This meta-theory provides deep and illuminating links with existing contract and interface theories, as well as guidelines for designing new theories. It encompasses contracts for both software and systems, with emphasis on the latter. Contracts for System Design illustrates the use of contracts with two examples: requirement engineering for a parking garage management, and the development of contracts for timing and scheduling in the context of the AUTOSAR methodology in use in the automotive sector.
