Download or read book Modeling Time in Computing written by Carlo A. Furia and published by Springer Science & Business Media. This book was released on 2012-10-19 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Models that include a notion of time are ubiquitous in disciplines such as the natural sciences, engineering, philosophy, and linguistics, but in computing the abstractions provided by the traditional models are problematic and the discipline has spawned many novel models. This book is a systematic thorough presentation of the results of several decades of research on developing, analyzing, and applying time models to computing and engineering. After an opening motivation introducing the topics, structure and goals, the authors introduce the notions of formalism and model in general terms along with some of their fundamental classification criteria. In doing so they present the fundamentals of propositional and predicate logic, and essential issues that arise when modeling time across all types of system. Part I is a summary of the models that are traditional in engineering and the natural sciences, including fundamental computer science: dynamical systems and control theory; hardware design; and software algorithmic and complexity analysis. Part II covers advanced and specialized formalisms dealing with time modeling in heterogeneous software-intensive systems: formalisms that share finite state machines as common “ancestors”; Petri nets in many variants; notations based on mathematical logic, such as temporal logic; process algebras; and “dual-language approaches” combining two notations with different characteristics to model and verify complex systems, e.g., model-checking frameworks. Finally, the book concludes with summarizing remarks and hints towards future developments and open challenges. The presentation uses a rigorous, yet not overly technical, style, appropriate for readers with heterogeneous backgrounds, and each chapter is supplemented with detailed bibliographic remarks and carefully chosen exercises of varying difficulty and scope. The book is aimed at graduate students and researchers in computer science, while researchers and practitioners in other scientific and engineering disciplines interested in time modeling with a computational flavor will also find the book of value, and the comparative and conceptual approach makes this a valuable introduction for non-experts. The authors assume a basic knowledge of calculus, probability theory, algorithms, and programming, while a more advanced knowledge of automata, formal languages, and mathematical logic is useful.

Download or read book The Inverse Method written by Etienne André and published by John Wiley & Sons. This book was released on 2013-02-20 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces state-of-the-art verification techniques for real-time embedded systems, based on the inverse method for parametric timed automata. It reviews popular formalisms for the specification and verification of timed concurrent systems and, in particular, timed automata as well as several extensions such as timed automata equipped with stopwatches, linear hybrid automata and affine hybrid automata. The inverse method is introduced, and its benefits for guaranteeing robustness in real-time systems are shown. Then, it is shown how an iteration of the inverse method can solve the good parameters problem for parametric timed automata by computing a behavioral cartography of the system. Different extensions are proposed particularly for hybrid systems and applications to scheduling problems using timed automata with stopwatches. Various examples, both from the literature and industry, illustrate the techniques throughout the book. Various parametric verifications are performed, in particular of abstractions of a memory circuit sold by the chipset manufacturer ST-Microelectronics, as well as of the prospective flight control system of the next generation of spacecraft designed by ASTRIUM Space Transportation. Contents: 1. Parametric Timed Automata. 2. The Inverse Method for Parametric Timed Automata. 3. The Inverse Method in Practice: Application to Case Studies. 4. Behavioral Cartography of Timed Automata. 5. Parameter Synthesis for Hybrid Automata. 6. Application to the Robustness Analysis of Scheduling Problems. 7. Conclusion and Perspectives.

Download or read book Prototyping of Concurrent Control Systems Implemented in FPGA Devices written by Remigiusz Wiśniewski and published by Springer. This book was released on 2016-09-30 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on prototyping aspects of concurrent control systems and their further implementation and partial reconfiguration in programmable devices. Further, it lays out a full prototyping flow for concurrent control systems. Based on a given primary specification, a system is described with an interpreted Petri net, which naturally reflects the concurrent and sequential relationships of the design. The book shows that, apart from the traditional option of static configuration of the entire system, the latest programmable devices (especially FPGAs) offer far more sophistication. Partial reconfiguration allows selected parts of the system to be replaced without having to reprogram the entire structure of the device. Approaches to dynamic and static partial reconfiguration of concurrent control systems are presented and described in detail.“/p> The theoretical work is illustrated by examples drawn from various applications, with a milling machine and a traffic-light controller highlighted as representative interpreted Petri nets. Given the ubiquity of concurrent control systems in a huge variety of technological areas including transportation, medicine, artificial intelligence, manufacturing, security and safety and planetary exploration, the innovative software and hardware design methods described here will be of considerable interest to control engineers and systems and circuits researchers in many areas of industry and academia.

Available in PDF, EPUB and Kindle. Book excerpt: Paradigms of Concurrency: Observations, Behaviours, and Systems - a Petri Net View - Ryszard Janicki (McMaster University, CA) Jetty Kleijn (Leiden University, NL) Maciej Koutny (Newcastle University, UK) Lukasz Mikulski (Nicolaus Copernicus University, PL) Concurrency can be studied at different yet consistent levels of abstraction: from individual behavioural observations via more abstract concurrent histories that can be represented by causality structures capturing invariant dependencies between executed actions, to system level constructs such as Petri nets or process algebra expressions. Histories can then be understood as sets of closely related observations. Depending on the nature of the observed relationships between executed actions involved in a single concurrent history, one may identify different concurrency paradigms underpinned by different kinds of causality structures such as partial orders. This book studies fundamental mathematical abstractions to capture and relate observations, histories, and systems. In particular, taking a Petri net view, we present system models fitting various concurrency paradigms and their associated causality structures.

Download or read book From Time Petri Nets to Timed Automata written by Franck Cassez and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this chapter, we have presented time Petri Nets (TPNs) and a structural translation from TPNs to TA. Any TPN T and its associated TA (T ) are timed bisimilar. Such a translation has many theoretical implications. Most of the positive theoretical results on TA carry over to TPNs. The class of TPNs can be extended by allowing strict constraints (open, half-open or closed intervals) to specify the firing dates of the transitions; for this extended class, the following results follow from our translation and from Theorem 5: ? TCTL model checking is decidable for bounded TPNs. Moreover efficient algorithms used in U PPAAL (Pettersson and Larsen, 2000) and K RONOS (Yovine, 1997) are exact for the class of TA obtained with our translation; ? it is decidable whether a TA is non-zeno or not (Henzinger et al., 1994) and thus our result provides a way to decide non-zenoness for bounded TPNs; ? lastly, as our translation is structural, it is possible to use a model-checker to find sufficient conditions of unboundedness of the TPN. These results enable us to use algorithms and tools developed for TA to check quantitative properties on TPNs. For instance, it is possible to check real-time properties expressed in the logic TCTL on bounded TPNs. The tool R OMEO (Gardey et al., 2005) that has been developed for the analysis of TPN (state space computation and "on-the-fly" model-checking of reachability properties) implements this translation of a TPN into the equivalent TA in U PPAAL input format. Our approach turns out to be a good alternative to existing methods for verifying TPNs: ? with our translation and U PPAAL we were able to check safety properties on very large TPNs that cannot be handled by other existing tools; ? we also extend the class of properties that can be checked on TPNs to real-time quantitative properties. Note also that using our translation, we can take advantage of all the features of a tool like U PPAAL : looking for counter examples is usually much faster than checking a safety property. Moreover if a safety property is false, we will obtain a counter example even for unbounded TPNs (if we use breadth-first search). There are currently new features being developed for tools like R OMEO that enables one to directly check TCTL properties on a TPN without translating it into a TA. Aknowledgments The authors wish to thank Didier Lime for his careful reading of this chapter and useful comments to improve many parts of the text.
Download or read book Handbook of Finite State Based Models and Applications written by Jiacun Wang and published by CRC Press. This book was released on 2012-10-16 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applicable to any problem that requires a finite number of solutions, finite state-based models (also called finite state machines or finite state automata) have found wide use in various areas of computer science and engineering. Handbook of Finite State Based Models and Applications provides a complete collection of introductory materials on finite state theories, algorithms, and the latest domain applications. For beginners, the book is a handy reference for quickly looking up model details. For more experienced researchers, it is suitable as a source of in-depth study in this area. The book first introduces the fundamentals of automata theory, including regular expressions, as well as widely used automata, such as transducers, tree automata, quantum automata, and timed automata. It then presents algorithms for the minimization and incremental construction of finite automata and describes Esterel, an automata-based synchronous programming language for embedded system software development. Moving on to applications, the book explores regular path queries on graph-structured data, timed automata in model checking security protocols, pattern matching, compiler design, and XML processing. It also covers other finite state-based modeling approaches and applications, including Petri nets, statecharts, temporal logic, and UML state machine diagrams.
