This book was released on 2005-04-04 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is dedicated to a novel approach for uniform modeling of timed and hybrid systems. The author introduces a time model that allows for both the description of discrete time steps and continuous processes with a discrete time model with infinitesimal step widths. The underlying mathematical structure of this time model is based on the concepts of non-standard analysis. The discrete modeling, i.e., the description of sequential discrete algorithms at different abstraction levels, is done using the abstract state machines formalism. The presentation is well balanced between theoretical elaboration and critical discussion of the applicability of the theoretical results by means of appropriate case studies. The new temporal semantics proposed helps theoreticians as well as practitioners in gaining a better understanding of time models and in building better notations, models, and tools for the formal treatment of systems where time matters.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph is dedicated to a novel approach for uniform modelling of timed and hybrid systems. Heinrich Rust presents a time model which allows for both the description of discrete time steps and continuous processes with a dense real-number time model. The proposed time model is well suited to express synchronicity of events in a real-number time model as well as strict causality by using uniform discrete time steps. Thus it integrates and reconciles two views of time that are commonly used separately in di?erent application domains. In many discrete systems time is modelled by discrete steps of uniform length, in continuous systems time is seen as a dense ?ow.

The underlying mathematical structure of this time model is based on concepts of Non-standard Analysis as proposed by Abraham Robinson in the 1950s. The discrete modelling, i.e., the descr- tion of sequential discrete algorithms at di?erent abstraction levels, is done with Abstract State Machines along the formalisms developed by Yuri Gu- vich and temporal logic. These ingredients produce a rich formal basis for describing a large variety of systems with quantitative linear time prop- ties, by seamless integration, re?nement and embedding of continuous and discrete models into one uniform semantic framework called“Non-standard Timed Abstract State Machines”(NTASM).

Download or read book Model Based Engineering of Embedded Real Time Systems written by Holger Giese and published by Springer. This book was released on 2010-10-09 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thetopicof“Model-BasedEngineeringofReal-TimeEmbeddedSystems”brings together a challenging problem domain (real-time embedded systems) and a - lution domain (model-based engineering). It is also at the forefrontof integrated software and systems engineering, as software in this problem domain is an essential tool for system implementation and integration. Today, real-time - bedded software plays a crucial role in most advanced technical systems such as airplanes, mobile phones, and cars, and has become the main driver and - cilitator for innovation. Development, evolution, veri?cation, con?guration, and maintenance of embedded and distributed software nowadays are often serious challenges as drastic increases in complexity can be observed in practice. Model-based engineering in general, and model-based software development in particular, advocates the notion of using models throughout the development and life-cycle of an engineered system. Model-based software engineering re- forces this notion by promoting models not only as the tool of abstraction, but also as the tool for veri?cation, implementation, testing, and maintenance. The application of such model-based engineering techniques to embedded real-time systems appears to be a good candidate to tackle some of the problems arising in the problem domain.
Download or read book Real time Systems written by Aurel Cornell and published by World Scientific. This book was released on 2007 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book collects the research work of leading-edge researchers and practitioners in the areas of analysis, synthesis, design and implementation of real-time systems with applications in various industrial fields. Their works are grouped into six parts, together encompassing twenty chapters. Each part is devoted to a mainstream subject, the chapters therein developing one of the major aspects of real-time system theory, modeling, design, and practical applications. Starting with a general approach in the area of formalization of real-time systems, and setting the foundations for a general systemic theory of those systems, the book covers everything from building modeling frameworks for various types of real-time systems, to verification, and synthesis. Other parts of the book deal with subjects related to tools and applications of these systems. A special part is dedicated to languages used for their modeling and design. The applications presented in the book reveal precious insights into practitionersOCO secrets."

Download or read book Real Time Systems written by Ernst-Rüdiger Olderog and published by Cambridge University Press. This book was released on 2008-09-11 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time systems need to react to certain input stimuli within given time bounds. For example, an airbag in a car has to unfold within 300 milliseconds in a crash. There are many embedded safety-critical applications and each requires real-time specification techniques. This text introduces three of these techniques, based on logic and automata: duration calculus, timed automata, and PLC-automata. The techniques are brought together to form a seamless design flow, from real-time requirements specified in the duration calculus; via designs specified by PLC-automata; and into source code for hardware platforms of embedded systems. The syntax, semantics, and proof methods of the specification techniques are introduced; their most important properties are established; and real-life examples illustrate their use. Detailed case studies and exercises conclude each chapter. Ideal for students of real-time systems or embedded systems, this text will also be of great interest to researchers and professionals in transportation and automation.

Download or read book Advances in Intelligent Systems written by Francesco Carlo Morabito and published by IOS Press. This book was released on 1997 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intelligent Systems can be defined as systems whose design, mainly based on computational techniques, is supported, in some parts, by operations and processing skills inspired by human reasoning and behaviour. Intelligent Systems must typically operate in a scenario in which non-linearities are the rule and not as a disturbing effect to be corrected. Finally, Intelligent Systems also have to incorporate advanced sensory technology in order to simplify man-machine interactions. Several algorithms are currently the ordinary tools of Intelligent Systems. This book contains a selection of contributions regarding Intelligent Systems by experts in diverse fields. Topics discussed in the book are: Applications of Intelligent Systems in Modelling and Prediction of Environmental Changes, Cellular Neural Networks for NonLinear Filtering, NNs for Signal Processing, Image Processing, Transportation Intelligent Systems, Intelligent Techniques in Power Electronics, Applications in Medicine and Surgery, Hardware Implementation and Learning of NNs.

Download or read book Concurrent and Real time Systems written by Steve Schneider and published by John Wiley & Sons. This book was released on 1999-11-15 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CSP approach has been widely used in the specification, analysis and verification of concurrent and real-time systems, and for understanding the particular issues that can arise when concurrency is present. It provides a language which enables specifications and designs to be clearly expressed and understood, together with a supporting theory which allows them to be analyzed and shown to be correct. This book supports advanced level courses on concurrency covering timed and untimed CSP. The first half introduces the language of CSP, the primary semantic models (traces, failures, divergences and infinite traces), and their use in the modelling, analysis and verification of concurrent systems. The second half of the book introduces time into the language, brings in the timed semantic model (timed failures) and finally presents the theory of timewise refinement which links the two halves together.
