Book Description
Erste Untersuchungen der Halswirbelsäule werden stets mit Hilfe von Röntgenaufnahmen durchgeführt, und in den meisten Fällen genügen diese als Grundlage für die Diagnose. Mißbildungen, Tumoren, und noch öfter Traumata, Rheuma und sogar ganz gewöhnliche Nackenschmerzen erfordern eine radiologische Untersuchung der Wirbelsäule. Die Auswertung jedoch ist schwierig. Nimmt man einen Halswirbel in die Hand, so stellt man fest, um welch komplexes Gebilde es sich hierbei handelt. Bei radiologischen Aufnahmen wird die Auswertung noch durch die sich überlappenden Knochenteile, Anhäufungen und die verschiedenen Blickwinkel erschwert. Das Buch von J.-F. Bonneville und F. Cattin stellt eine originelle Interpretationsmethode von Röntgenaufnahmen vor, die die Auswertung wesentlich erleichtert. Dieses Buch zeigt, daß zwei- bzw. dreidimensionale Computertomogramme eine ausgezeichnete Hilfe zum Verständnis von konventionellen Röntgenbildern sein können. Der Leser bekommt gleichsam Zugang zu jedem Einzelteil des Knochens, und von da an wird alles einfach, Überlappungen verschwinden, die in der Röntgenaufnahme verborgenen Tücken werden sichtbar, die Anatomie triumphiert, das Bild lebt. Die Halswirbelsäule von J.-F. Bonneville und F. Cattin ist unentbehrlich für jeden Radiologen in seiner täglichen Praxis, aber ebenso auch für Chirurgen, Rheumatologen und Physiotherapeuten, die sich für die Halswirbelsäule interessieren.

Book Description
This volume presents the proceedings of the 2nd VDM-Europe Symposium held in Dublin, Ireland, September 12-16, 1988. VDM, the Vienna Development Method, is a formal method for software engineering. It is being applied to an increasing number of projects by companies throughout Europe and there is an active international research programme supporting this process. "VDM - The Way Ahead" is the second of a series of symposia sponsored by the Commission of the European Communities (CEC) and organised by VDM-Europe. The term "formal method" refers to mathematically formal software specification and production methods. These methods aim to increase the quality of software in two related ways: by improving the specification and by making verification during the software production process more effective and easier to audit. The symposium proceedings focus on five areas of interest: education and technology transfer, experience and use of VDM, tools and support environments, method development and foundation at work, the standardisation of VDM. The proceedings are of interest to all those concerned with the application of more rigorous approaches to software development and the associated theoretical foundations.

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 VDM Europe, formed in 1985 as an advisory board sponsored by the Commission of the European Communities. The VDM Europe working group consisted of researchers, software engineers, and programmers, allinterested in promoting 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 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. Volume 2 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
In software engineering there is a growing need for formalization as a basis for developing powerful computer assisted methods. This volume contains seven extensive lectures prepared for a series of IFIP seminars on the Formal Description of Programming Concepts. The authors are experts in their fields and have contributed substantially to the state of the art in numerous publications. The lectures cover a wide range in the theoretical foundations of programming and give an up-to-date account of the semantic models and the related tools which have been developed in order to allow a rigorous discussion of the problems met in the construction of correct programs. In particular, methods for the specification and transformation of programs are considered in detail. One lecture is devoted to the formalization of concurrency and distributed systems and reflects their great importance in programming. Further topics are the verification of programs and the use of sophisticated type systems in programming. This compendium on the theoretical foundations of programming is also suitable as a textbook for special seminars on different aspects of this broad subject.

Book Description
In this book the author explains domain engineering and the underlying science, and he then shows how we can derive requirements prescriptions for computing systems from domain descriptions. A further motivation is to present domain descriptions, requirements prescriptions, and software design specifications as mathematical quantities. The author's maxim is that before software can be designed we must understand its requirements, and before requirements can be prescribed we must analyse and describe the domain for which the software is intended. He does this by focusing on what it takes to analyse and describe domains. By a domain we understand a rationally describable discrete dynamics segment of human activity, of natural and man-made artefacts, examples include road, rail and air transport, container terminal ports, manufacturing, trade, healthcare, and urban planning. The book addresses issues of seemingly large systems, not small algorithms, and it emphasizes descriptions as formal, mathematical quantities. This is the first thorough monograph treatment of the new software engineering phase of software development, one that precedes requirements engineering. It emphasizes a methodological approach by treating, in depth, analysis and description principles, techniques and tools. It does this by basing its domain modeling on fundamental philosophical principles, a view that is new for a computer science monograph. The book will be of value to computer scientists engaged with formal specifications of software. The author reveals this as a field of interesting problems, most chapters include pointers to further study and exercises drawn from practical engineering and science challenges. The text is supported by a primer to the formal specification language RSL and extensive indexes.

Book Description
The reliability of software is becoming increasingly important to a large range of industries that rely on complex computer systems and machinery with computer control. The reliability of a system depends on both the hardware and the software that comprise the system. Although faults in design can continue to give problems, the issues and the techniques for meeting severe reliability requirements in hardware have been understood for some time. In the case of software both the techniques and a positive attitude of software developers to the achievement of reliability are much less well established. They are particularly crucial in the development of software dependent safety-critical systems.

Book Description
In October 1983 an informal meeting was organized in Le Cap d'Agde with the help of the BIGRE bulletin. Sixty people turned out to hear more than ten presentations on object-oriented programming. More important was their unanimous demand for other, more structured encounters. So, about one year later, the Object group was created by AFCET. A second workshop was organized in Brest, and again one year later in Paris, each time showing increased attendance and interest. The success of these meetings and the fact that similar activities were taking place in other European countries, especially Great Britain and Germany, led to the idea of an annual European Conference, providing a forum for theorists and practitioners interested in the object-oriented programming paradigm. It is impossible to acknowledge here all the people and organizations that welcomed with great enthusiasm the birth of the ECOOP conference and contributed to its organization. More than a hundred submissions were received and the program committee had the unpleasant task of turning down many valuable contributions. We hope, however, that the selection of papers for ECOOP'87 emphasizes the fundamental issues and problems of object-oriented programming and will point toward interesting future research directions.

Book Description
The last few years have borne witness to a remarkable diversity of formal methods, with applications to sequential and concurrent software, to real-time and reactive systems, and to hardware design. In that time, many theoretical problems have been tackled and solved, and many continue to be worked upon. Yet it is by the suitability of their industrial application and the extent of their usage that formal methods will ultimately be judged. This volume presents the proceedings of the first international symposium of Formal Methods Europe, FME'93. The symposium focuses on the application of industrial-strength formal methods. Authors address the difficulties of scaling their techniques up to industrial-sized problems, and their suitability in the workplace, and discuss techniques that are formal (that is, they have a mathematical basis) and that are industrially applicable. The volume has four parts: - Invited lectures, containing a lecture by Cliff B. Jones and a lecture by Antonio Cau and Willem-Paul de Roever; - Industrial usage reports, containing 6 reports; - Papers, containing 32 selected and refereedpapers; - Tool descriptions, containing 11 descriptions.

Book Description
The goal of this book is to provide a comprehensive and systematic introduction to the important and highly applicable method of data refinement and the simulation methods used for proving its correctness. The authors concentrate in the first part on the general principles needed to prove data refinement correct. They begin with an explanation of the fundamental notions, showing that data refinement proofs reduce to proving simulation. The book's second part contains a detailed survey of important methods in this field, which are carefully analysed, and shown to be either incomplete, with counterexamples to their application, or to be always applicable whenever data refinement holds. This is shown by proving, for the first time, that all these methods can be described and analysed in terms of two simple notions: forward and backward simulation. The book is self-contained, going from advanced undergraduate level and taking the reader to the state of the art in methods for proving simulation.
