Hybrid systems are networks of interacting digital andanalog devices. Control systems for inherently unstableaircraft and computer aided manufacturing are typicalapplications for hybrid systems, but due to the rapiddevelopment of processor and circuit technology modern carsand consumer electronics use software to control physicalprocesses. The identifying characteristic of hybrid systemsis that they incorporate both continuous components governedby differential equations and also digital components -digital computers, sensors, and actuators controlled byprograms.This volume of invited refereed papers is inspired by aworkshop on the Theory of Hybrid Systems, held at theTechnical University, Lyngby, Denmark, in October 1992, andby a prior Hybrid Systems Workshop, held at CornellUniversity, USA, in June 1991, organized by R.L. Grossmanand A. Nerode. Some papers are the final versions of paperspresented at these workshops and some are invited papersfrom other researchers who were not able to attend theseworkshops.

This book constitutes the refereed proceedings of the 5th International Symposium on Formal Techniques in Real-Time and Fault-Tolerant Systems, FTRTFT'98, held in Lyngby, Denmark, in September 1998.The 22 revised full papers presented were carefully selected and reviewed for inclusion in the book. Also included are four invited contributions and five tool demonstrations. The papers address the current aspects of the hot topic of embedded systems, in particular temporal logic, requirements engineering, analysis techniques, verification, model checking, and applications.

This book constitutes the proceedings of the 7th International Symposium on Automated Technology for Verification and Analysis, ATVA 2009, held in Macao, China, in October 2009. The 23 regular papers and 3 took papers presented together with 3 invited talks, were carefully reviewed and selected from 74 research papers and 10 tool papers submissions. The papers are organized in topical sections on state space reduction, tools, probabilistic systems, medley, temporal logic, abstraction and refinement, and fault tolerant systems.
