Our understanding of real-time systems is rapidly approaching a level of maturity which calls for a consolidation of our present knowledge and experience. Particularly effective in influencing our understanding has been the conjoining of universal algebra with the theory and practice of real-time system development. This interplay between algebraic methodology and software technology (AMAST) for real-time systems is the theme for this text.Each chapter, derived from papers presented at the all-invitation 1st AMAST International Workshop on Real-Time Systems (Iowa, 1993), is written by leaders in their field. The chapters form an intriguing mix of modeling, specification, verification, and implementation of “real” real-time systems. They cover untimed and timed systems, sequential, concurrent and embedded real-time processes, integrated models using state machines, temporal logic and algebraic data models, real-time CSP, verification tools, system design using temporal logic, symbolic checking of discrete time models, iterative symbolic approximation in timing verification and verification of audio protocols, timed full LOTOS and timed LOTOS extensions, LOTOS specification of telephone services and flight warning computers, and performance analysis.

Theories And Experiences For Real-time System Development

Robert George Clark

This book is concerned with the theory and techniques required in the construction and implementation of complex software systems. Improved understanding may come from developing suitable models and theories of such systems to guide appropriate experimentation. Alternatively, standard mathematical theories and constructions may provide techniques directly usable in the design and implementation of new software. In any case, the use of these approaches involves the development of new tools, and using them leads to further insights which can improve the original theories and models. The contributors to this book cover all these many aspects involved in the origin, development, and refinement of software systems. Some chapters break new ground, some represent the next stage in ongoing research programs, and others describe the next generation of software tools. In addition to a readership of software engineers and computer scientists, the book offers a source of interesting research problems for mathematicians, whose work is vital for the continued development of the field.

Modern European architecture has been characterised by a strong undercurrent of rationalist thought. Rationalist Traces aims to examine this legacy by establishing a cross-section of contemporary European architecture, placed in selected national contexts by critics including Ákos Moravánszky and Josep Maria Montaner. Subsequent interviews discuss the theoretical contributions of Giorgio Grassi and OM Ungers, and a survey of Max Dudler and De Architekten Cie.’s work sets out a consistency at one remove from avant-garde spectacle or everyday expediency. In Germany Rationalism offers a considered representation of state institutions, while elsewhere outstanding work reveals different approaches to rationality in architecture often recalling canonical Modernism or the ‘Rational Architecture’ of the later postwar period. Whether evident in patterns of thinking, a particular formal repertoire, a prevailing consistency or exemplified in individual buildings, this relationship informs the mature work of Patrick Berger, Claus en Kaan Architecten, Carlos Ferrater, Cino Zucchi or Hans Kollhoff. The buildings and projects of a younger generation – Javier García Solera, GWJ Architekten AG, biq, Andrea Bassi or Beniamino Servino – present a Rationalism less conditioned by a concern to promote a unifying aesthetic. While often sharing a deliberate economy of means, or a sensual sobriety, they present a more oblique or distanced relationship with the defining work of the 20th century.

This book constitutes the refereed proceedings of the 10th International Conference on Algebraic Methodology and Software Technology, AMAST 2004, held in Stirling, Scotland, UK in July 2004. The 35 revised full papers presented together with abstracts of 5 invited talks and an invited paper were carefully reviewed and selected from 63 submissions. Among the topics covered are all current issues in formal methods related to algebraic approaches to software engineering including abstract data types, process algebras, algebraic specification, model checking, abstraction, refinement, model checking, state machines, rewriting, Kleene algebra, programming logic, etc.

Algebraic Methodology and Software Technology

The goal of the AMAST conferences is to foster algebraic methodology as a foundation for software technology, and to show that this can lead to practical mathematical alternatives to the ad-hoc approaches commonly used in software engineering and development. The first two AMAST conferences, held in May 1989 and May 1991 at the University of Iowa, were well received and encouraged the regular organization of further AMAST conferences on a biennial schedule. The third Conference on Algebraic Methodology and Software Technology was held in the campus of the University of Twente, The Netherlands, during the first week of Summer 1993. Nearly a hundred people from all continents attended the conference. The largest interest received by the AMAST conference among the professionals extended to include the administration organizations as well. AMAST'93 was opened by the Rector of the University of Twente, followed by the Local Chairman. Their opening addresses open this proceedings, too. The proceedings contains 8 invited papers and 32 selected communica tions. The selection was very strict, for 121 submissions were received.

Algebraic Methodology and Software Technology (AMAST’93)

This volume contains the proceedings of the Second International Conference on Algebraic Methodology and Software Technology (AMAST '91). The aim of the AMAST conferences is to promote the use of algebraic methodology as a foundation for software technology, and to examine how it can be used to provide practical mathematical alternatives to the ad hoc methods commonly used in software development. In particular the conferences provide a showcase for software systems which have been developed in this way, focusing on the conceptual developments which made them possible. The resulting volume covers a variety of software development issues, and testifies to the versality of algebraic methods when used as conceptual tools in the software development process. It features a distinguished collection of invited papers from leading researchers in the field, many of which break new ground, or represent an important step forward in current research. Among the specific topics covered are: language design; compiler construction; software testing; symbolic computation and partial evaluation; incremental implementation; and the verification of program and specification properties. Algebraic Methodology and Software Technology (AMAST '91) provides a comprehensive overview of this important field of science. It will provide invaluable reading for students and researchers, both in industry and academia.

Algebraic Methodology and Software Technology (AMAST'91)

This volume contains papers presented at the BCS-FACS Workshop on Specification and Verification of Concurrent Systems held on 6-8 July 1988, at the University of Stirling, Scotland. Specification and verification techniques are playing an increasingly important role in the design and production of practical concurrent systems. The wider application of these techniques serves to identify difficult problems that require new approaches to their solution and further developments in specification and verification. The Workshop aimed to capture this interplay by providing a forum for the exchange of the experience of academic and industrial experts in the field. Presentations included: surveys, original research, practical experi ence with methods, tools and environments in the following or related areas: Object-oriented, process, data and logic based models and specifi cation methods for concurrent systems Verification of concurrent systems Tools and environments for the analysis of concurrent systems Applications of specification languages to practical concurrent system design and development. We should like to thank the invited speakers and all the authors of the papers whose work contributed to making the Workshop such a success. We were particularly pleased with the international response to our call for papers. Invited Speakers Pierre America Philips Research Laboratories University of Warwick Professor M.
