Book Description
The proceedings of the fourth Vienna Development Method Symposium, VDM '91, are published here in two volumes. Previous VDM symposia were held in 1987 (LNCS 252), 1988 (LNCS 328), and 1990 (LNCS 428). The VDM symposia have been organized by the VDM Europe, formed in 1985 as an advisory board sponsored by the Commission of the European Communities. The VDM Europe working group consisted of reasearchers, software engineers, and programmers, all interested in prommoting the industrial usage of formal methods for software development. The fourth VDM symposium presented not only VDM but also a large number of other methods for formal software development. Volume 1 contains the conference contributions. It has four parts: contributions of invited speakers, papers, project reports, and tools demonstration abstracts. The emphasis is on methods and calculi for development, verification and verification tools support, experiences from doing developments, and the associated theoretical problems. Volume2 contains four introductory tutorials (on LARCH, Refinement Calculus, VDM, and RAISE) and four advanced tutorials (on ABEL, PROSPECTRA, THE B Method, and The Stack). They present a comprehensive account of the state of theart.

Book Description
This book contains the edited versions of papers presented at the Fourth Irish Conference on Artificial Intelligence and Cognitive Science (AICS'91), which was held at University College, Cork, Ireland on 19-20 September 1991. The main aims of this annual conference series are to promote AI research in Ireland, to provide a forum for the exchange of ideas amongst different disciplines concerned with the study of cognition, and to provide an opportunity for industry to see what research is being carried out in Ireland and how it might benefit from the results of this research. While most of the participants at the conference came from universities and companies within Ireland, a positive feature was the interest shown from outside the country, resulting in participants from Britain, USA and Italy. The keynote speaker was Professor James A. Bowen, North Carolina State University, who spoke on future trends in knowledge representation. The topics covered in the presented papers included fundamental approaches to AI, natural language, knowledge representation, information retrieval, deduction, epistemics and vision. The sponsors of the conference were Digital Equipment Co. (Galway) and Eolas, the Irish Science and Technology Board.

Book Description
This volume contains a selection of papers presented at the second European workshop EUROCAST '91, held in Krems, Austria, in April 1991. It gives an overview of the current state of Computer Aided Systems Theory research and its relation to CAD applications in the engineering fields. CAST research requires the application of the most advanced information processing technology in software and hardware for the implementation of CAST method base systems. Engineers in the field of information and control engineering have the opportunity in CAST to present the state ofthe art in modeling tools to computer scientists. EUROCAST '91 proved that CAST research is still in an early state of development. The papers in the volume are organized into sections on systems theory and CAST methodology, modeling environments, CAST method base systems and artificial vision, and information and control systems.

Book Description
Refinement is the term used to describe systematic and formal methods of specifying hard- and software and transforming the specifications into designs and implementations. The value of formal methods in producing reliable hard- and software is widely appreciated by academics and workers in industry, despite the fact that certain research areas, such as the application to industrial-scale problems, are still in their infancy. This volume contains the papers presented at the 5th Refinement Workshop held in London, 8-10 January 1992. Its theme was the theory and practice of software specifications, which is the transformation of formal software specifications into more correct specifications, designs and codes. This has been an important area of research for the last 5 years and the workshop addressed specific issues and problems related to it. Among the topics discussed in this volume are: the role of refinement in software development, parallel designs and implementations, methods and tools for verification of critical properties, refinement and confidentiality, concurrent processes as objects, the compliance of Ada programs with Z specifications and a tactic driven refinement tool. This is the latest refinement workshop proceedings to be published in the Workshops in Computing series (the 3rd and 4th workshops having appeared in 1990 and 1991 respectively). It will be of interest to academic and industrial researchers, postgraduate students and research-oriented developers in the computer industry.

Book Description
Despite the volume of research carried out into the design of database systems and the design of user interfaces, there is little cross-fertilization between the two areas. The control of user interfaces to database systems is, therefore, significantly less advanced than other aspects of DBMS design. As database functionality is used in a wider range of areas, such as design applications, the suitability of the user interface is becoming increasingly important. It is, therefore, necessary to begin applying the knowledge developed by HCI researchers to the specialised domain of database systems. This volume contains revised papers from the International Workshop on Interfaces to Database Systems, held in Glasgow, 1-3 July 1992. The workshop aimed to develop an interaction between the design of database systems and user interfaces. It discussed both the production of interfaces tailored to particular applications, and also more general systems within which interfaces can be developed. Some of the papers concentrate on usability aspects, some discuss different interface metaphors, whilst others tackle the question of designing a general conceptual model. The latter topic is of particular importance, as it is only by achieving an abstract model of what the user understands to be in the database that the data can be associated with appropriate interface facilities. Among the contents of the volume are: integrated interfaces to publicly available databases; database query interface for medical information systems; an integrated approach to task oriented database retrieval interfaces; GRADI: a graphical database interface for a multimedia DBMS; cognitive view mechanism for multimedia information systems; a graphical schema representation for object oriented databases; a conceptual framework for error analysis in SQL interfaces; a browser for a version entity relationship database. Interfaces to Database Systems (IDS92) is unique in that it brings together a variety of approaches from the database and HCI research communities. It will provide essential reading for researchers of database systems and also industrial developers of DBMS.

Book Description
This volume contains papers from the North American Process Algebra Workshop, held in Stony Brook, New York, 28 August 1992. This was the first in a proposed series of workshops, intended to increase awareness of process algebras in the United States and Canada, and to promote their use and development. The workshop was held simultaneously with CONCUR 92, the annual conference on concurrency theories. It provided an important forum for the discussion and exchange of ideas, and allowed recent developments in the application of algebraic techniques to concurrency theory to be presented. The resulting volume provides a good cross-section of current research work in Canada, USA and Europe. Among the specific topics covered are: real-time calculi and expansion theorems; modal logics in timed process algebra; process communication environment; a process calculus with incomparable priorities; exception handling in process algebra; bisimulations on observation structures; computing ready simulations efficiently; analysis of value-passing CCS agents with infinite sorts; an extension of the testing method for processes passing infinite values; constructive semantics; a causality-based semantics for CCS. NAPAW 92 provides an comprehensive overview of this important, up-and-coming area of computer science. It will provide essential reading for both postgraduate students and researchers in industry and academia.

Book Description
Logic and object-orientation have come to be recognized as being among the most powerful paradigms for modeling information systems. The term "information systems" is used here in a very general context to denote database systems, software development systems, knowledge base systems, proof support systems, distributed systems and reactive systems. One of the most vigorously researched topics common to all information systems is "formal modeling". An elegant high-level abstraction applicable to both application domain and system domain concepts will always lead to a system design from "outside in"; that is, the aggregation of ideas is around real-life objects about which the system is to be designed. Formal methods \yhen applied with this view in mind, especially during early stages of system development, can lead to a formal reasoning on the intended properties, thus revealing system flaws that might otherwise be discovered much later. Logic in different styles and semantics is being used to model databases and their transactions; it is also used to specify concurrent, distributed, real-time, and reactive systems. ,The notion of "object" is central to the modeling of object oriented databases, as well as object-oriented design and programs in software engineering. Both database and software engineering communities have undoubtedly made important contributions to formalisms based on logic and objects. It is worthwhile bringing together the ideas developed by the two communities in isolation, and focusing on integrating their common strengths.

Book Description
The scientific developments at the end of the past millennium were dominated by the huge increase and diversity of disciplines with the common label "computer science". The theoretical foundations of such disciplines have become known as theoretical computer science. This book highlights some key issues of theoretical computer science as they seem to us now, at the beginning of the new millennium. The text is based on columns and tutorials published in the Bulletin of the European Association for Theoretical Computer Science in the period 1995 -- 2000. The columnists themselves selected the material they wanted for the book, and the editors had a chance to update their work. Indeed, much of the material presented here appears in a form quite different from the original. Since the presentation of most of the articles is reader-friendly and does not presuppose much knowledge of the area, the book constitutes suitable supplementary reading material for various courses in computer science.

Book Description
Since its conception nearly 20 years ago, logic programming has been developed to the point where it now plays an important role in areas such as database theory, artificial intelligence and software engineering. There are, however, still many outstanding research issues which need to be addressed, and the UK branch of the Association for Logic Programming was set up to provide a forum where the flourishing research community could discuss important issues which were often by- passed at the larger international conferences. This volume contains the invited papers, refereed papers and tutorials presented at the 4th ALPUK Conference, which aimed to broaden the frontiers of logic programming by encouraging interaction between it and other related disciplines. The papers cover a variety of technical areas, including concurrent logic languages and their semantics, applications of logic languages to other (non-classical) logical systems, modules, types and error-handling, and the distributed execution of Prolog programs. The wide scope of the papers refelects the breadth of interest in this important area of computer science. ALPUK 92 provides a comprehensive overview of current progress being made in logic programming research. It will be of interest to all workers in the field, especially researchers, postgraduate students, and research and development workers in industry.
