VLSI Specification, Verification and Synthesis (The Springer International Series in Engineering and Computer Science #35)

by Graham Birtwistle P. A. Subrahmanyam

VLSI Specification, Verification and Synthesis Proceedings of a workshop held in Calgary from 12-16 January 1987. The collection of papers in this book represents some of the discussions and presentations at a workshop on hardware verification held in Calgary, January 12-16 1987. The thrust of the workshop was to give the floor to a few leading researchers involved in the use of formal approaches to VLSI design, and provide them ample time to develop not only their latest ideas but also the evolution of these ideas. In contrast to simulation, where the objective is to assist in detecting errors in system behavior in the case of some selected inputs, the intent of hardware verification is to formally prove that a chip design meets a specification of its intended behavior (for all acceptable inputs). There are several important applications where formal verification of designs may be argued to be cost-effective. Examples include hardware components used in "safety critical" applications such as flight control, industrial plants, and medical life-support systems (such as pacemakers). The problems are of such magnitude in certain defense applications that the UK Ministry of Defense feels it cannot rely on commercial chips and has embarked on a program of producing formally verified chips to its own specification. Hospital, civil aviation, and transport boards in the UK will also use these chips. A second application domain for verification is afforded by industry where specific chips may be used in high volume or be remotely placed.

Wissensrepräsentation in Expertensystemen: Workshop, Herrenberg, 16.–18. März 1987 Proceedings (Informatik-Fachberichte #172)


Das Buch enthält die Beiträge des Workshops "Wissensrepräsentation in Expertensystemen", der vom 16. bis 18.3.1987 von der IBM Deutschland GmbH in Herrenberg durchgeführt wurde. Wissensrepräsentation ist für viele Anwendungen der Künstlichen Intelligenz von zentraler Bedeutung. Bei der Umsetzung von Ergebnissen der Forschung in Anwendungen wird die Wissensrepräsentation wegen ihrer Verankerung in so verschiedenen Gebieten wie Logik, Linguistik und Psychologie unübersichtlich. Es gibt keine einheitliche Systematisierung. Hinzu kommt, daß die Probleme der Wissensrepräsentation erst an größeren Anwendungen in ihrer vollen Tragweite erkennbar werden. In dem Workshop wurde daher versucht, das Thema interdisziplinär und systematisch zu behandeln. Dabei ging es weniger um die Darstellung von Projekten, bei denen die Wissensrepräsentation meistens nur peripher und unter spezifischen Projektaspekten diskutiert wird, sondern um eine gezielte Thematisierung der zentralen Fragestellungen in aufeinander abgestimmten Abschnitten: Orientierung und Grundlagen, Sprachen und Methoden der Wissensrepräsentation, Spezifische Teilprobleme (Raum- und Zeitaspekte), Wissenserwerb und Wissensverarbeitung. Das Buch stellt in konzentrierter Form Beiträge von herausragenden Forschern auf diesem Gebiet zusammen.

The Human Use Of Human Beings: Cybernetics And Society

by Norbert Wiener

Only a few books stand as landmarks in social and scientific upheaval. Norbert Wiener's classic is one in that small company. Founder of the science of cybernetics-the study of the relationship between computers and the human nervous system-Wiener was widely misunderstood as one who advocated the automation of human life. As this book reveals, his vision was much more complex and interesting. He hoped that machines would release people from relentless and repetitive drudgery in order to achieve more creative pursuits. At the same time he realized the danger of dehumanizing and displacement. His book examines the implications of cybernetics for education, law, language, science, technology, as he anticipates the enormous impact-in effect, a third industrial revolution-that the computer has had on our lives.

Active Computer Vision by Cooperative Focus and Stereo (Springer Series in Perception Engineering)

by Eric P. Krotkov

This book addresses an area of perception engineering which deals with constructive processes. A model of the environment is analyzed using the information acquired from mUltiple viewpoints of multiple disparate sensors at multiple time instants. Although the role of successive model building and active exploration of the environment, as is discussed in this book, is of great importance, only a few researchers of machine perception have thus far addressed the problem in these directions. Krotkov's book, which is a modification and continuation of his highly successful dissertation, focuses on active exploratory sensing in the context of spatial layout perception. He uses stereo and focus to obtain distance By information, and to eventually develop cooperative combining techniques. means of a stereo system with verging cameras, it is demonstrated that the distance measurements can be significantly improved by combining two sources. In addition, the problem of merging information from the multiple views is discussed in detail. As the field of perception engineering seems to be of growing scientific and applied importance, both practitioners and researchers in machine perception will find this book a valuable addition to their libraries. RameshJain Series Editor Acknowledgements I would like to thank Professor Ruzena Bajcsy for her constant encouragement and guidance during the five years of research leading to the dissertation upon which this book is based. Without her help in all matters, this work would never have been possible.

Advanced Information Technologies for Industrial Material Flow Systems (NATO ASI Subseries F: #53)

by Shimon Y. Nof Colin L. Moodie

This book contains the results of an Advanced Research Workshop that took place in Grenoble, France, in June 1988. The objective of this NATO ARW on Advanced Information Technologies for Industrial Material Flow Systems (MFS) was to bring together eminent research professionals from academia, industry and government who specialize in the study and application of information technology for material flow contro!' The current world status was reviewed and an agenda for needed research was discussed and established. The workshop focused on the following subjects: The nature of information within the material flow domain. Status of contemporary databases for engineering and material flow. Distributed databases and information integration. Artificial intelligence techniques and models for material flow problem solving. Digital communications for material flow systems. Robotics, intelligent systems, and material flow contro!' Material handling and storage systems information and contro!' Implementation, organization, and economic research-issues as related to the above. Material flow control is as important as manufacturing and other process control in the computer integrated environment. Important developments have been occurring internationally in information technology, robotics, artificial intelligence and their application in material flow/material handling systems. In a traditional sense, material flow in manufacturing (and other industrial operations) consists of the independent movement of work-in-process between processing entities in order to fulfill the requirements of the appropriate production and process plans. Generally, information, in this environment, has been communicated from processors to movers.

Advances in Computer Graphics V (Focus on Computer Graphics)

by Werner Purgathofer Jürgen Schönhut

This book collects together several of the tutorials held at EUROGRAPHICS'89 in Hamburg. The conference was held under the motto "Integration, Visualisation, Interaction" and the tutorials reflect the conference theme. The Springer series EurographicSeminars with the volumes "Advances in Computer Graphics" regularly provides a professional update on current mainstream topics in the field. These publications give readers the opportunity to inform themselves thoroughly on the topics covered. The success of the series is mainly based on the expertise of the contributing authors, who are recognized professionals in their field. Starting out with one of the conference's main topics, the chapter "Visualization of Scientific Data" gives an overview of methods for displaying scientific results in an easily surveyable and comprehensible form. It presents algorithms and methods utilized to achieve visualization results in a form adequate for humans. User interfaces for such systems are also explored, and practical conclusions are drawn. The chapter "Color in Computer Graphics" describes the problems of manipulating and matching color in the real world. After some fundamental statements about color models and their relationships, the main emphasis is placed on the problem of objective color specification for computer graphics systems. It is very hard to match colors between devices such as scanners, printers and displays. Some suggestions on the effective use of color for graphics are also made.

Algebraic Specifications in Software Engineering: An Introduction

by Ivo Van Horebeek Johan Lewi

"I prefer to view formal methods as tools. the use of which might be helpful." E. W. Dijkstra Algebraic specifications are about to be accepted by industry. Many projects in which algebraic specifications have been used as a design tool have been carried out. What prevents algebraic specifications from breaking through is the absence of introductory descriptions and tools supporting the construction of algebraic specifications. On the one hand. interest from industry will stimulate people to make introductions and tools. whereas on the other hand the existence of introductions and tools will stimulate industry to use algebraic specifications. This book should be seen as a contribution towards creating this virtuous circle. The book will be of interest to software designers and programmers. It can also be used as material for an introductory course on algebraic specifications and software engineering at undergraduate or graduate level. Nowadays. there is general agreement that in large software projects appropriate specifications are a must in order to obtain quality software. Informal specifications alone are certainly not appropriate because they are incomplete. inconsistent. inaccurate and ambiguous and they rapidly become bulky and therefore useless. The only way to overcome this problem is to use formal specifications. An important remark here is that a specification formalism (language) alone is not sufficient. What is also needed is a design method to write specifications in that formalism.

Algorithm Synthesis: A Comparative Study

by David M. Steier A. Penny Anderson

In early 1986, one of us (D.M.S.) was constructing an artificial intelligence system to design algorithms, and the other (A.P.A.) was getting started in program transformations research. We shared an office, and exchanged a few papers on the systematic development of algorithms from specifications. Gradually we realized that we were trying to solve some of the same problems. And so, despite radical differences between ourselves in research approaches, we set out together to see what we could learn from these papers. That's how this book started: a couple of graduate students trying to cope with The Literature. At first, there was just a list of papers. One of us (D.M.S.) tried to cast the papers in a uniform framework by describing the problem spaces searched, an approach used in artificial intelligence for understanding many tasks. The generalized problem space descriptions, though useful, seemed to abstract too much, so we decided to compare papers by different authors dealing with the same algorithm. These comparisons proved crucial: for then we began to see similar key design choices for each algorithm.

Algorithms and Model Formulations in Mathematical Programming (NATO ASI Subseries F: #51)

by Stein W. Wallace

The NATO Advanced Research Workshop (ARW) "Algorithms and Model Formulations in Mathematical Programming" was held at Chr. Michelsen Institute in Bergen, Norway, from June 15 to June 19, 1987. The ARW was organized on behalf of the Committee on Algorithms (COAL) of the Mathematical Programming Society (MPS). Co-directors were Jan Telgen (Van Dien+Co Organisatie, Utrecht, The Netherlands) and Roger J-B Wets (The University of California at Davis, USA). 43 participants from 11 countries attended the ARW. The workshop was organized such that each day started with a - minute keynote presentation, followed by a 45-minute plenary discussion. The first part of this book contains the contributions of the five keynote speakers. The plenary discussions were taped, and the transcripts given to the keynote speakers. They have treated the transcripts differently, some by working the discussions into their papers, others by adding a section which sums up the discussions. The plenary discussions were very interesting and stimulating due to active participation of the audience. The five keynote speakers were asked to view the topic of the workshop, the interaction between algorithms and model formulations, from different perspectives. On the first day of the workshop Professor Alexander H.G. Rinnooy Kan (Erasmus University, Rotterdam, The Netherlands) put the theme into a larger context by his talk "Mathematical programming as an intellectual activity". This is an article of importance to any mathematical programmer who is interested in his field's history and present state.

Algorithms and Order (Nato Science Series C: #255)

by Ivan Rival

This volume contains the texts of the principal survey papers presented at ALGORITHMS -and ORDER, held· at Ottawa, Canada from June 1 to June 12, 1987. The conference was supported by grants from the N.A.T.O. Advanced Study Institute programme, the University of Ottawa, and the Natural Sciences and Engineering Research Council of Canada. We are grateful for this considerable support. Over fifty years ago, the Symposium on Lattice Theory, in Charlottesville, U.S.A., proclaimed the vitality of ordered sets. Only twenty years later the Symposium on Partially Ordered Sets and Lattice Theory, held at Monterey, U.S.A., had solved many of the problems that had been originally posed. In 1981, the Symposium on Ordered Sets held at Banff, Canada, continued this tradition. It was marked by a landmark volume containing twenty-three articles on almost all current topics in the theory of ordered sets and its applications. Three years after, Graphs and Orders, also held at Banff, Canada, aimed to document the role of graphs in the theory of ordered sets and its applications. Because of its special place in the landscape of the mathematical sciences order is especially sensitive to new trends and developments. Today, the most important current in the theory and application of order springs from theoretical computer seience. Two themes of computer science lead the way. The first is data structure. Order is common to data structures.

Analog VLSI Implementation of Neural Systems (The Springer International Series in Engineering and Computer Science #80)

by Carver Mead Mohammed Ismail

This volume contains the proceedings of a workshop on Analog Integrated Neural Systems held May 8, 1989, in connection with the International Symposium on Circuits and Systems. The presentations were chosen to encompass the entire range of topics currently under study in this exciting new discipline. Stringent acceptance requirements were placed on contributions: (1) each description was required to include detailed characterization of a working chip, and (2) each design was not to have been published previously. In several cases, the status of the project was not known until a few weeks before the meeting date. As a result, some of the most recent innovative work in the field was presented. Because this discipline is evolving rapidly, each project is very much a work in progress. Authors were asked to devote considerable attention to the shortcomings of their designs, as well as to the notable successes they achieved. In this way, other workers can now avoid stumbling into the same traps, and evolution can proceed more rapidly (and less painfully). The chapters in this volume are presented in the same order as the corresponding presentations at the workshop. The first two chapters are concerned with fmding solutions to complex optimization problems under a predefmed set of constraints. The first chapter reports what is, to the best of our knowledge, the first neural-chip design. In each case, the physics of the underlying electronic medium is used to represent a cost function in a natural way, using only nearest-neighbor connectivity.

Analogical Modeling of Language

by R. Skousen

1. Structuralist Versus Analogical Descriptions ONE important purpose of this book is to compare two completely dif­ ferent approaches to describing language. The first of these approaches, commonly called stnlctllralist, is the traditional method for describing behavior. Its methods are found in many diverse fields - from biological taxonomy to literary criticism. A structuralist description can be broadly characterized as a system of classification. The fundamental question that a structuralist description attempts to answer is how a general contextual space should be partitioned. For each context in the partition, a rule is defined. The rule either specifies the behavior of that context or (as in a taxonomy) assigns a name to that context. Structuralists have implicitly assumed that descriptions of behavior should not only be correct, but should also minimize the number of rules and permit only the simplest possible contextual specifications. It turns out that these intuitive notions can actually be derived from more fundamental statements about the uncertainty of rule systems. Traditionally, linguistic analyses have been based on the idea that a language is a system of rules. Saussure, of course, is well known as an early proponent of linguistic structuralism, as exemplified by his characterization of language as "a self-contained whole and principle of classification" (Saussure 1966:9). Yet linguistic structuralism did not originate with Saussure - nor did it end with "American structuralism".
