It is also ideally suited for prototyping.
This book is intended for both beginners and experts. With its carefully chosen blend of theory and practice, and extensive use of examples and case studies, this book will provide an invaluable guide to all those needing to learn about or using the ISPF Dialog Manager.

This book is the final outcome of the Eurographics Workshop on Design, Specification and Verification of Interactive Systems, that was held in Bonas, from June 7 to 9, 1995. This workshop was the second of its kind, following the successful first edition in Italy in 1994. The goal of this ongoing series of meetings is to review the state of the art in the domain of tools, notations and methodologies supporting the design of Interactive Systems. This acknowledges the fact that making systems that are friendlier to the user makes the task ever harder to the designers of such systems, and that much research is still needed to provide the appropriate conceptual and practical tools. The workshop was located in the Chateau de Bonas, in the distant countryside of Toulouse, France. Tms location has been selected to preserve the quiet and studious atmosphere that was established in the monastery of Santa Croce at Bocca di Magra for the first edition, and that was much enjoyed by the participants. The conversations initiated during the sessions often lasted till late at night, in the peaceful atmosphere of the Gers landscape.

This book presents two major research results on the fast implementation of graph rewriting systems (GRS). First, it explores the class of so-called UBS-GRS, where the complexity of a rewriting step is linear instead of NP, showing for example that visual programming is possible by UBS graph rewriting. Second, an abstract machine for graph rewriting is defined providing an instruction set sufficient for the execution of GRS.
The basic definitions of GRS in the algorithmic approach are introduced and extended by attribution and control structures to comprise a formalism for an operational specification. The translation of a functional programming language to graph rewriting shows the capabilities of UBS-GRS.

This volume documents the concepts, experiences, results, and conclusions of the ESPRIT project NEUTRABAS (Neutral Product Definition Database for Large Multifunctional Systems). It deals with the development of a database for large multifunctional systems, in particular for ships and their multitudinous, complex subsystems. NEUTRABAS was the first European project aiming at an international standard based on ISO standard 10303 (STEP) methodology to define a comprehensive information model for ships and similar products of complex functionality, which will serve for the exchange and long term storage of product information. NEUTRABAS contributed to the first generation of shipbuilding product models and gained first experiences in implementing databases exploiting the new technology of the STEP standard.

Concurrent design, or co-design of hardware and software is extremely important for meeting design goals, such as high performance, that are the key to commercial competitiveness. Hardware/Software Co-Design covers many aspects of the subject, including methods and examples for designing: (1) general purpose and embedded computing systems based on instruction set processors; (2) telecommunication systems using general purpose digital signal processors as well as application specific instruction set processors; (3) embedded control systems and applications to automotive electronics. The book also surveys the areas of emulation and prototyping systems with field programmable gate array technologies, hardware/software synthesis and verification, and industrial design trends. Most contributions emphasize the design methodology, the requirements and state of the art of computer aided co-design tools, together with current design examples.

It is probably an overstatement to say that the discipline of telecommunication systems is becoming an application of digital signal processing (DSP). However, there is no doubt that by the mid-I980s integrated circuit technology has advanced to such an extent that revolutionary advances in telecommunications are fostered by the introduction of new and poweiful DSP algorithms. Actually, DSP has been recently playing a major role in the development of telecommuni cations systems: to name just one of the most widespread applications where this interaction has been most effective, we may mention the use of intelligent DSP to improve the peiformance of transmission systems by allowing sophisticated algorithm to be implemented in radio transmitters and receivers for personal communications. Other areas have equally benefited by the latest advances of DSP: speech coding and synthesis, speech recognition and enhancement, radar, sonar, digital audio, and remote sensing, just to cite afew. With this in mind, when choosing the topic for the 7th Tyrrhenian Workshop on Digital Communications, whose contributions are collected in this book, we aimed at focusing on the state of the art and the perspectives of the interaction between DSP and telecommunications, two disciplines that are becoming increasingly intertwined. Although by no means exhaustive of all the applications of DSP to telecommu nications, we believe that the material presented in this book pinpoints the most interesting among them, and hence it will be considered as a useful tool for investigating this complex and highly challenging field."

One of the most significant developments in computing over the last ten years has been the growth of interest in computer based support for people working together. Recognition that much work done in offices is essentially group work has led to the emergence of a distinct subfield of computer science under the title Computer Supported Cooperative Work (CSCW). Since the term was first coined in 1984, there has been growing awareness of the relevance to the field of, and the valuable con tributions to be made by, non-computing disciplines such as sociology, management science, social psychology and anthro pology. This volume addresses design issues in CSCW, an- since this topic crucially involves human as well as technical considerations - brings together researchers from such a broad range of disciplines. Most of the chapters in this volume were originally presented as papers at the one-day seminar, "Design Issues in CSCW," held at the Department of Trade and Industry (DTI), London, on 17 March 1992, one in aseries of DTI-supported CSCW SIG seminars. We would like to express our gratitude to the series editors, Colston Sanger and Dan Diaper, for their useful comments on, and suggestions for revisions to, the final draft of the manuscript; to Linda Schofield, our editor at Springer, for her continued encouragement throughout the preparation of the manuscript; and, finally, to our respective families for their support and patience over so many months."

Computing, despite the relative brevity of its history, has already evolved into a subject in which a fairly large number of subdisciplines can be identified. Moreover, there has been a noticeable tendency for the different branches of the subject each to develop its own intellectual culture, tradition and momentum. This is not, of course, to suggest that any individ ual subdiscipline has become a watertight compartment or that developments in one branch of the subject have tended to take place in total isolation from developments in other related areas. Nevertheless, it does mean that a deliberate effort is required in order to bring different subdisciplines together in a fruitful and beneficial manner. Artificial Intelligence (AI) and Computer Supported Coopera tive Work (CSCW) jointly constitute a good example of two branches of computing that have emerged separately and given rise to largely distinct research communities and initiatives. On the one hand, the history of AI can be traced back to the 1950s, the term II Artificial Intelligence" being generally attributed to John McCarthy, who first used it in print in 1956. "Computer Supported Cooperative Work," on the other hand, is a term of more recent coinage, having'been devised by Irene Greif and Paul Cashman in 1984."

Conventional object-oriented data models are closed: although they allow users to define application-specific classes, they usually come with a fixed set of modelling primitives. This constitutes a major problem, as different application domains, e.g. database integration or multimedia, need special support.
Using an extended metaclass concept, this book provides for the solution of this problem a simple but extendible open object-oriented data model, a so-called RISC model. By introducing the basic concepts of the open object-oriented database management system VODAK, it demonstrates how the extended metaclass concept can be integrated homogeneously into object-oriented data models.

This volume contains thoroughly refereed and revised full papers selected from the presentations at the first workshop held under the auspices of the ESPRIT Basic Research Action 6453 Types for Proofs and Programs in Nijmegen, The Netherlands, in May 1993.
As the whole ESPRIT BRA 6453, this volume is devoted to the theoretical foundations, design and applications of systems for theory development. Such systems help in designing mathematical axiomatisation, performing computer-aided logical reasoning, and managing databases of mathematical facts; they are also known as proof assistants or proof checkers.

In total, the volume gives a thorough state-of-the-art report on current research and advanced applications in advanced information systems engineering.

This volume contains the papers selected after a very careful refereeing process for presentation during the Workshop on Job Scheduling Stategies for Parallel Processing, held in Santa Barbara, California, as a prelude to the IPPS '95 conference in April 1995.
The 19 full papers presented demonstrate that parallel job scheduling takes on a crucial role as multi-user parallel supercomputers become more widespread. All aspects of job scheduling for parallel systems are covered, from the perspectives of academic research, industrial design of parallel systems, as well as user needs. Of particular interest, also for nonexpert readers, is the introductory paper "Parallel Job Scheduling: Issues and Approaches" by the volume editors.

This volume contains the papers presented at the Intemational Conference on Object Oriented Information Systems 00lS'94, held at South Bank University, London, December 19 - 21, 1994. In response to our call for papers, a total 85 papers from 24 different countries were submitted. Each paper was evaluated by at least two Program Committee members and an additional reviewer. Together, we selected 41 papers for presentation at the conference and inclusion in the Proceedings. Also included are the keynote addresses by Peter Gray and Michael Jackson. The other submissions were recommended for presentation in the poster sessions. Peter Gray, our invited speaker, evaluates the problems of object-oriented systems and data independence by looking at how object oriented database applications are failing to perceive its benefits, and instead rely too much on encapsulation. He suggests alternative kinds of object storage to preserve data independence. The second invited speaker, Michael Jackson describes a way of solving problems, by focusing directly on the problems themselves, their components and structures and on the relationships between the problem and the solution method. He discusses a particular view of the role of object-orientation in software development.

Fault tolerance has been an active research area for many years. This volume presents papers from a workshop held in 1993 where a small number of key researchers and practitioners in the area met to discuss the experiences of industrial practitioners, to provide a perspective on the state of the art of fault tolerance research, to determine whether the subject is becoming mature, and to learn from the experiences so far in order to identify what might be important research topics for the coming years. The workshop provided a more intimate environment for discussions and presentations than usual at conferences. The papers in the volume were presented at the workshop, then updated and revised to reflect what was learned at the workshop.
