An Introduction to Default Logic (Symbolic Computation)

by Philippe Besnard

This book is written for those who are interested in a fonnalization of human reasoning, especially in order to build "intelligent" computer systems. Thus, it is mainly designed for the Artificial Intelligence community, both students and researchers, although it can be useful for people working in related fields like cognitive psychology. The major theme is not Artificial Intelligence applications, although these are discussed throughout in sketch fonn. Rather, the book places a heavy emphasis on the fonnal development of default logic, results and problems. Default logic provides a fonnalism for an important part of human reasoning. Default logic is specifically concerned with common sense reasoning, which has recently been recognized in the Artificial Intelligence literature to be of fundamental importance for knowledge representation. Previously, fonnalized reasoning systems failed in real world environments, though succeeding with an acceptable ratio in well-defined environments. This situation enabled empirical explorations and the design of systems without theoretical justification. In particular, they could not be compared since there was no basis to judge their respective merits. Default logic turned out to be very fruitful by proving the correctness of some of them. We hope that this book will initiate other successful developments in default logic.

Einstein Manifolds (Classics In Mathematics Ser.)

by Arthur L. Besse

Einstein's equations stem from General Relativity. In the context of Riemannian manifolds, an independent mathematical theory has developed around them. This is the first book which presents an overview of several striking results ensuing from the examination of Einstein’s equations in the context of Riemannian manifolds. Parts of the text can be used as an introduction to modern Riemannian geometry through topics like homogeneous spaces, submersions, or Riemannian functionals.

Petri Net Primer: A Compendium on the Core Model, Analysis, and Synthesis (Computer Science Foundations and Applied Logic)

by Eike Best Raymond Devillers

Petri nets model concurrent and distributed systems where active components communicate through the production and absorption of various kinds of resources. Although the dynamic properties of such systems may be very complex, they may sometimes be connected to the static structure of a Petri net. Many properties are decidable, but their complexity may be huge. It is often opportune to restrict oneself to classes of systems, to partial algorithms, and to similar but simpler properties. Instead of analysing a given system, it is also possible to search for a system satisfying some desired properties by construction. This comprehensive textbook/reference presents and discusses these issues in-depth in the context of one of the most fundamental Petri net models, called place/transition nets. The presentation is fortified by means of many examples and worked exercises. Among topics addressed: • In which order may actions may be generated and scheduled? • What states and configurations may be reached in a concurrent system? • Which interesting classes of systems can be analysed relatively efficiently? • Is it possible to synthesise a system of some class from its behaviour? • How can systems be represented algebraically, compositionally, and concisely? This unique text, based on introductory as well as on advanced courses on distributed systems, will serve as an invaluable guide for students and (future) researchers interested in theoretical—as well as in practical—aspects of Petri nets and related system models. Eike Best has been a full professor (now retired) affiliated to Carl von Ossietzky Universität Oldenburg, Germany. Raymond Devillers has been a full professor (now retired) affiliated to Université Libre de Bruxelles, Belgium. The authors have a long record as collaborators in the fields of Petri nets and the semantics of concurrency.

Petri Net Algebra (Monographs in Theoretical Computer Science. An EATCS Series)

by Eike Best Raymond Devillers Maciej Koutny

In modern society services and support provided by computer-based systems have become ubiquitous and indeed have started to fund amentally alter the way people conduct their business. Moreover, it has become apparent that among the great variety of computer technologies available to potential users a crucial role will be played by concurrent systems. The reason is that many commonly occurring phenomena and computer applications are highly con­ current : typical examples include control systems, computer networks, digital hardware, business computing, and multimedia systems. Such systems are characterised by ever increasing complexity, which results when large num­ bers of concurrently active components interact. This has been recognised and addressed within the computing science community. In particular, sev­ eral form al models of concurrent systems have been proposed, studied, and applied in practice. This book brings together two of the most widely used formalisms for de­ scribing and analysing concurrent systems: Petri nets and process algebras. On the one hand , process algebras allow one to specify and reason about the design of complex concurrent computing systems by means of algebraic operators corresponding to common programming constructs. Petri nets, on the other hand, provide a graphical representation of such systems and an additional means of verifying their correctness efficiently, as well as a way of expressing properties related to causality and concurrency in system be­ haviour.

Nonsequential Processes: A Petri Net View (Monographs in Theoretical Computer Science. An EATCS Series #13)

by Eike Best Cesar Fernandez C.

The theory of Petri nets is a part of computer science whose importance is increasingly acknowledged. Many papers and anthologies, whose subject matter is net theory and its applications, have appeared to date. There exist at least seven introductory textbooks on the theory. The present monograph augments this literature by offering a mathematical treatment of one of the central aspects of net theory: the modelling of concur­ rency by partially ordered sets. Occurrence nets - which are special nets as well as special partial orders - are proposed by net theory for this purpose. We study both the general properties of occurrence nets and their use in describing the concurrent behaviour of systems. Occurrence nets may be contrasted with a more language-oriented approach to the modelling of concurrency known as arbitrary interleaving. We will dis­ cuss some connections between these' two approaches. Other approaches based on partially ordered sets - such as the theory of traces, the theory of event structures and the theory of semi words - are not considered in this book, in spite of the strong links between them and net theory.

Strategic Stability in the Post-Cold War World and the Future of Nuclear Disarmament (NATO Science Partnership Subseries: 1 #3)

by Melvin L. Best

This Report contains a Consensus Report and the papers submitted to the April 6 -10, 1995 NATO Advanced Research Workshop on Strategic Stability In The Post-Cold War World And The Future Of Nuclear Disarmament, held in Washington D. C. , United States Of America of at The Airlie Conference Center. The workshop was sponsored by the NATO Division Scientific and Environmental Affairs as part of its ongoing outreach programme to widen and deepen scientific contacts between NATO member countries and the Cooperation Partner countries of the former Warsaw Treaty Organization. The participants recognize that the collapse of the former Soviet Union has left a conceptual vacuum in the definition of a new world order. Never before have the components of world order all changed so rapidly, so deeply, or so globally. As Henry Kissinger points out, the emergence of the new world order will have answered three fundamental questions:" What are the basic units of the international order? What are their means of interacting? and What are the goals on behalf of which they interact? " The main question is whether the establishment and maintenance of an international system will turn out to be a conscious design, or the outgrowth of a test of strength. The concept of a planning framework that could shape or govern these interactions is emerging and may now be at hand. Capturing this emerging framework is the thrust of this NATO-sponsored Advanced Research Workshop.

Accounting for Construction: Frameworks, Productivity, Cost and Performance

by Rick Best Jim Meikle

Accounting for Construction follows on from Measuring Construction, edited by the same team. It extends the coverage of some of the material in the first volume and expands the range of related topics to include, inter alia, shadow economies, accounting for informal construction and the treatment of the built environment sector in national accounts. Taken together, the two volumes collate a range of topics that are only addressed, if addressed at all, in occasional academic papers and the publications of bodies such as national statistical offices and the World Bank. Accounting for Construction presents international examples from the UK, Australia and New Zealand and from both academic and professional contributors. This book is essential reading for all researchers and professionals interested in construction economics, construction management, and anyone interested in how the construction industry affects the global economy in ways previously under-represented in the literature.

Fehlerkultur in Organisationen: Eine organisationsethnografische Studie in der stationären Altenpflege (Organisation und Pädagogik #33)

by Kerstin Bestvater

Im Zentrum dieser Studie steht die Frage nach der Verflechtung der Fehlerkultur mit den Entscheidungs- und Handlungspraktiken in einer Alten- und Pflegeeinrichtung. Dafür wurde mit der pädagogischen Organisationsethnografie ein explorativer Zugang zum Forschungsgegenstand gewählt, der einen tiefen Einblick in die soziale Welt der Altenpflege gewährt. Kernstück ist eine konzeptualisierende Darstellung feldtypischer Praktiken und eine gegenstandsbezogene Theorieentwicklung, die im Sinne der Grounded Theory umgesetzt wurde. Das genuine Dilemma der Altenpflege zwischen Wirtschaftlichkeit und Pflegeethos führt zu Praxismustern, die als Problemlösungsstrategien auch die Fehlerkultur prägen.
