This book was released on 1987-07-15 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference manual of ANNA is another volume addressed to the ADA community. ANNA is a language extension of ADA to include facilities for formally specifying the intended behavior of ADA programs. It is designed to meet a perceived need to augment ADA with precise machine-processable annotations so that well established formal methods of specification and documentation can be applied to ADA programs. The current ANNA design includes annotations of all ADA constructs except tasking. Similar extensions for formal specification can be made to other Algol-like languages such as Pascal, PL/1, Concurrent Pascal, and Modula; essentially, these extensions would be subsets of ANNA. The design of ANNA was undertaken from the beginning with four principal considerations: 1. Constructing annotations should be easy for the ADA programmer and should depend as much as possible on notation and concepts of ADA. 2. ANNA should possess language features that are widely used in the specification and documentation of programs. 3. ANNA should provide a framework within which the various established theories of formally specifying programs may be applied to ADA. 4. Annotations should be equally well suited for different possible applications during the life cycle of a program. Such applications include not only testing, debugging and formal verification of a finished program, but also specification of program parts during the earlier stages of requirements analysis and program design.

This book was released on 2013-11-11 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1989 Workshop on the Assessment of Formal Methods for Trustworthy Com puter Systems (FM89} was an invitational workshop that brought together repre sentatives from the research, commercial and governmental spheres of Canada, the United Kingdom, and the United States. The workshop was held in Halifax, Nova Scotia, Canada, from July 23 through July 27, 1989. This document reports the activities, observations, recommendations and conclusions resulting. from FM89. 1. 1 Purpose of Workshop The primary purpose for holding FM89 was to assess the role of formal methods in the development and fielding of trustworthy critical systems. The need for this assessment was predicated upon four observations: 1. Critical systems are increasingly being controlled by computer systems; 2. Existing techniques for developing, assuring and certifying computer-based critical systems are inadequate; 3. Formal methods have the potential for playing the same role in the devel opment of computer-based systems as applied mathematics does for other engineering disciplines; and 4. Formal methods have had limited impact on the development of comput- based systems and supporting technologies. · The goal of the workshop was to complete the following tasks: 1. Assess the problems retarding the development of trustworthy critical systems; 2. Determine the (potential) impact of applying formal methods techniques to the development of trustworthy critical systems; 3. Determine the research and development required to facilitate a broader ap plication of formal methods techniques; 4.

Download or read book Programming with Specifications written by David Luckham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Topics • what this book is about, • its intended audience, • what the reader ought to know, • how the book is organized, • acknowledgements. Specifications express information about a program that is not normally part of the program, and often cannot be expressed in a programming lan guage. In the past, the word "specification" has sometimes been used to refer to somewhat vague documentation written in English. But today it indicates a precise statement, written in a machine processable language, about the purpose and behavior of a program. Specifications are written in languages that are just as precise as programming languages, but have additional capabilities that increase their power of expression. The termi nology formal specification is sometimes used to emphasize the modern meaning. For us, all specifications are formal. The use of specifications as an integral part of a program opens up a whole new area of programming - progmmming with specifications. This book describes how to use specifications in the process of building programs, debugging them, and interfacing them with other programs. It deals with a new trend in programming - the evolution of specification languages from the current generation of programming languages. And it describes new strategies and styles of programming that utilize specifications. The trend is just beginning, and the reader, having finished this book, will viii Preface certainly see that there is much yet to be done and to be discovered about programming with specifications.

Available in PDF, EPUB and Kindle. Book excerpt: The growing demand for systems of ever-increasing complexity and precision has stimulated the need for higher level concepts, tools, and techniques in every area of Computer Science. Some of these areas, in particular Artificial Intelligence, Databases, and Programming Lan guages, are attempting to meet this demand by defining a new, more abstract level of system description. We call this new level conceptual in recognition of its basic conceptual nature. In Artificial Intelligence, the problem of designing an expert system is seen primarily as a problem of building a knowledge base that repre sents knowledge about an enterprise. Consequently, Knowledge Repre sentation is viewed as a central issue in Artificial Intelligence research. Database design methodologies developed during the last five years are almost unanimous in offering semantic data models in terms of which the designer directly and naturally models an enterprise before proceed ing to a detailed logical and physical database design. In Programming Languages, different forms of abstraction which allow implementation independent specifications of data, functions, and control have been a major research theme for a decade. To emphasize the common goals of these three research efforts, we call this new activity conceptual modelling.

Download or read book Formal Specification Techniques for Engineering Modular C Programs written by Tan Yang Meng and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software is difficult to develop, maintain, and reuse. Two factors that contribute to this difficulty are the lack of modular design and good program documentation. The first makes software changes more difficult to implement. The second makes programs more difficult to understand and to maintain. Formal Specification Techniques for Engineering Modular C Programs describes a novel approach to promoting program modularity. The book presents a formal specification language that promotes software modularity through the use of abstract data types, even though the underlying programming language may not have such support. This language is structured to allow useful information to be extracted from a specification, which is then used to perform consistency checks between the specification and its implementation. Formal Specification Techniques for Engineering Modular C Programs also describes a specification-driven, software re-engineering process model for improving existing programs. The aim of this process is to make existing programs easier to maintain and reuse while keeping their essential functionalities unchanged. Audience: Suitable as a secondary text for graduate level courses in software engineering, and as a reference for researchers and practitioners in industry.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
