Principles of Computer Systems and Network Management

Understanding how the brain works is probably the greatest scientific and intellectual challenge of our generation. The cerebral cortex is the instrument by which we carry the most complex mental functions. Fortunately, there exists an immense body of knowledge concerning both cortical structure and the properties of single neurons in the cortex. With the advent of the supercomputer, there has been increased interest in neural network modeling. What is needed is a new approach to an understanding of the mammalian cerebral cortex that will provide a link between the physiological description and the computer model. This book meets that need by combining anatomy, physiology, and modeling to achieve a quantitative description of cortical function. The material is presented didactically, starting with descriptive anatomy and comprehensively examining all aspects of modeling. The book gradually leads the reader from the macroscopic cortical anatomy and standard electrophysiological properti

Human factors is one of the critical issues in Information Technology, as industry realizes the need to change from technology-oriented goals to meet the demands of computer users. Human factors can help to improve Informatics Usability for real people, and to reduce the huge people-costs of human machine interactions. This book has been developed from lectures given at an Advanced Study course, sponsored by the European Science and Technology Research Committee of the Commission of the European Communities (CREST), and by the Science and Engineering Research Council (SERC) of the UK. It has three objectives: 1. To review the knowledge and methods available from the field of human factors for improving the usability of informatics systems; 2. To describe recent theoretical and methodological developments in the area; 3. To stimulate increased application of this expertise.

In this 1991 book the author gives a broad overview of different areas of research in nonmonotonic reasoning, and presents some results and ideas based on his research. The guiding principles are: clarification of the different research activities in the area, which have sometimes been undertaken independently of each other, and appreciation of the fact that these research activities often represent different means to the same ends, namely sound theoretical foundations and efficient computation. The book begins with a discussion of the various types of nonmonotonic reasoning, their applications and their logics. Theorem proving techniques for these logics are also described. There then follow chapters dealing with formulations of nonmonotonic inheritance, and nonmonotonic reasoning based on nonmonotonic rules. The final chapter discusses the achievements in the field in the light of the famous Yale shooting example. The book will be welcomed by researchers in theoretical computer scien

This book is concerned with techniques for formal theorem-proving, with particular reference to Cambridge LCF (Logic for Computable Functions). Cambridge LCF is a computer program for reasoning about computation. It combines the methods of mathematical logic with domain theory, the basis of the denotational approach to specifying the meaning of program statements. Cambridge LCF is based on an earlier theorem-proving system, Edinburgh LCF, which introduced a design that gives the user flexibility to use and extend the system. A goal of this book is to explain the design, which has been adopted in several other systems. The book consists of two parts. Part I outlines the mathematical preliminaries, elementary logic and domain theory, and explains them at an intuitive level, giving reference to more advanced reading; Part II provides sufficient detail to serve as a reference manual for Cambridge LCF. It will also be a useful guide for implementors of other programs based on the LCF approa

This outstanding collection is designed to address the fundamental issues and principles underlying the task of Artificial Intelligence. The editors have selected not only papers now recognized as classics but also many specially commissioned papers which examine the methodological and theoretical foundations of the discipline from a wide variety of perspectives: computer science and software engineering, cognitive psychology, philosophy, formal logic and linguistics. Carefully planned and structured, the volume tackles many of the contentious questions of immediate concern to AI researchers and interested observers. Is Artificial Intelligence in fact a discipline, or is it simply part of computer science? What is the role of programs in AI and how do they relate to theories? What is the nature of representation and implementation, and how should the challenge of connectionism be viewed? Can AI be characterized as an empirical science? The comprehensiveness of this collection is furthe

This rigorous and practical account of the interpretation of mutagenicity test data draws upon the expertise of toxicologists and statisticians. Chemicals, such as drugs, food additives and pesticides, all need careful screening to eliminate potentially mutagenic compounds. Although guidelines exist on the performance of these tests, advice on data evaluation is scarce; this volume provides the statistical background necessary for toxicologists to understand, design and interpret mutagenicity tests. In addition to the nine chapters dealing with the different tests employed, there is an introductory chapter on some of the statistical principles involved, a glossary of useful terms and an appendix providing vital information on the availability of computer software. A large team of contributors and editors working under the auspices of the United Kingdom Environmental Mutagen Society (UKEMS) have contributed a wealth of first-hand experience in compiling this immensely practical book of

The hierarchy of states presents Ian Clark's Reform and resistance in the international order, a well-established text on international relations first published in 1980, in a completely revised form. Combining a detailed examination of theory with a full account of historical developments, Dr Clark analyses the nature of international order - the hierarchical state system - and its potential for reform. The theory of international order is explored tracing two traditions of thought epitomised in the writings of Kant and Rousseau, whilst in a historical survey Dr Clark covers the main attempts to implement international order since 1815 and includes such aspects as concert diplomacy, alliance systems, international organisations as well as such informal understandings as nuclear deterrence, crisis management and spheres of influence. This revised edition contains two new chapters - one on international/world order issues and the other on 'macro' changes between 1815 and 1990. Dr Clark

Ergonomics is a multi-disciplinary activity concerned mainly with people at work, but also with other human purposeful activities such as war, sport, games and leisure. The objective of ergonomics is to make these activities more effective and safer by applying established principles of anatomy, physiology and psychology. Together with the earlier volume, The Body at Work, this book forms a comprehensive textbook of ergonomics for all students of the subject, whether they be undergraduates or postgraduates on specialist ergonomics courses or those concerned with ergonomics as part of courses in psychology, physiology, management, industrial engineering and industrial design. This volume covers the psychological aspects of people at work; practices over the past twenty years stimulated by high technology systems and computerisation.

This 1989 book describes the physico-chemical principles of the high vacuum techniques used by chemists. It is a guide to the choice of suitable equipment, the methods of constructing the systems, and the ways of using them. Professor Plesch's book is the only up-to-date work on the type of high vacuum systems (HVS) used by chemists and it is the first ever to describe in detail the actual construction, manifold uses, method of operation, and final dismantling of an HVS. It includes descriptions of a very wide range of devices for making measurements (conductivity, spectra, kinetics, etc.) in vacuum. The author draws on over 40 years of his own experiences and those of others in many parts of the world, and many of the tricks and gadgets have not been published before. The book will be an essential companion on the bench of every chemist involved in the synthesis of, or measurements on, air-sensitive compounds.

This book brings together the most important topics in experimental particle physics over the past forty years to give a brief but balanced overview of the subject. The author begins by reviewing particle physics and discussing electromagnetic and nuclear interactions. He then goes on to discuss three nearly universal aspects of particle physics experiments: beams, targets, and fast electronics. The second part of the book treats in detail the properties of various types of particle detector, such as scintillation counters, Cerenkov counters, proportional chambers, drift chambers, sampling calorimeters, and specialized detectors. Wherever possible the author attempts to enumerate the advantages and disadvantages of performance. Finally, he discusses aspects of specific experiments, such as properties of triggers, types of measurement, spectrometers, and the integration of detectors into coherent systems. Throughout the book, each chapter begins with a discussion of the basic principles

Drugs affecting the nerves and the brain are among the most commonly used in contemporary medicine. This book examines the mechanism by which such substances cause their therapeutic effects or undesirable side-effects, in relation to underlying physiological and pathological processes. This new edition has been extensively revised and reorganised; the section on the autonomic system has been greatly expanded. Other changes reflect the significant advances in our understanding of drug action in the peripheral and central nervous systems which have arisen through the application of new electrophysiological and computer techniques. The volume summarises the explosion of information concerning endogenous opioids, other peptides, the benzodiazepines and their receptors. Later chapters deal with the activity and role of drugs in a number of disorders including epilepsy, schizophrenia and depression. This textbook is suitable for undergraduates in pre-clinical medical sciences, pharmaceutical

This is the third edition of a successful textbook, now with material added to illustrate the potential of computers for biologists. It is a lucid introduction to the principles and more elementary techniques of statistical reasoning, particularly as they are relevant to the biologist. Special attention is paid to the validity and use of statistical procedures, the interpretation of results, and the meanings of the conclusions which can then be drawn. The understanding of statistical methods is aided by full explanations of how calculations are built up. A particular feature of this edition is the inclusion, of new material to demonstrate the potential usefulness of computers in biological statistical analysis and to this end computer analyses of a selection of the examples are presented, using several different statistical languages. The examples are designed to guide and encourage the biologist to pursue the use of these languages further. The book assumes no mathematical training an

The many billions of dollars invested in canal irrigation in recent decades have had disappointing results. Rarely have projected benefits in well-being or production been achieved. In consequence, in the mid-1980s, further vast sums are being spent throughout the Third World on programmes for rehabilitation, canal lining, on farm development, and farmers' organisation. In this book, Robert Chambers shows that much of this policy and practice is based on misleading research and misdiagnosis. When applied to the complexity and uniqueness of canal irrigation systems, the normal professionalism of civil and agricultural engineers, agronomists, economists, and sociologists, leaves gaps which are keys to better performance. In successive chapters, five such gaps are analysed and presented: main system management, including the scheduling and delivery of water, and communications; canal irrigation at night; management of canal systems jointly by farmers and officials; professional conditions

Demonstrating the ways in which work in a broad range of fields can be pulled together in the analysis of conflict, this book provides the reader with a general introduction to the principles of conflict analysis and lays a methodological foundation for the further development of the interdisciplinary field of peace science. The text begins with an extensive survey of arms race models, from the classic Richardson model to models exploring the effects of factors such as the domestic and international economic environment, public opinion and party politics, and weapons technology and information development. The processes of individual and group problem-solving, in both crisis and non-crisis conditions, are examined, drawing on work in economics, operations research, cognitive science, and artificial intelligence. Building on this diverse body of work, the author moves on to develop a framework for conflict management with which to approach a variety of conflict situations and applies th

This classic book is a encylopaedic and comprehensive account of the classical theory of analytical dynamics. The treatment is rigorous yet readable, starting from first principles with kinematics before moving to equations of motion and specific and explicit methods for solving them, with chapters devoted to particle dyanmics, rigid bodies, vibration, and dissipative systems. Hamilton's principle is introduced and then applied to dynamical systems, including three-body systems and celestial mechanics. Very many examples and exercisies are supplied throughout.

Providing the first comprehensive overview of the method of crystal growth in gels, Professor Henisch reviews the field, covering the underlying physics as well as the empirical experience of growth techniques accumulated over the past century. In addition, the book discusses the phenomenon of periodic precipitation, which often governs the distribution of crystal in laboratory growth systems. For the first time, computer techniques are brought to bear on the subject, the diffusion equations being solved numerically, in association with the conditions governing precipitations and crystal growth.

Human Motivation, originally published in 1987, offers a broad overview of theory and research from the perspective of a distinguished psychologist whose creative empirical studies of human motives span forty years. David McClelland describes methods for measuring motives, the development of motives out of natural incentives and the relationship of motives to emotions, to values and to performance under a variety of conditions. He examines four major motive systems - achievement, power, affiliation and avoidance - reviewing and evaluating research on how these motive systems affect behaviour. Scientific understanding of motives and their interaction, he argues, contributes to understanding of such diverse and important phenomena as the rise and fall of civilisations, the underlying causes of war, the rate of economic development, the nature of leadership, the reasons for authoritarian or democratic governing styles, the determinants of success in management and the factors responsible

The designer of a software system, like the architect of a building, needs to be aware of the construction techniques available and to choose the ones that are the most appropriate. This book provides the implementer of software systems with a guide to 25 different techniques for the complete development processes, from system definition through design and into production. The techniques are described against a common background of the traditional development path, its activities and deliverable items. In addition the concepts of metrics and indicators are introduced as tools for both technical and managerial monitoring and control of progress and quality. The book is intended to widen the mental toolkit of system developers and their managers, and will also introduce students of computer science to the practical side of software development. With its wide-ranging treatment of the techniques available and the practical guidance it offers, it will prove an important and valuable work.

This is the third volume of the complete edition of The Correspondence of Charles Darwin. For the first time full authoritative texts of Darwin's letters are available, edited according to modern textual editorial principles and practice. The letters in this volume were written during the years 1844–6. By 1844 Darwin had become an established figure within the circle of London naturalists and his life at Down had assumed the regularity that the responsibility for a thriving and growing household entailed. Despite his move to rural Kent, Darwin was not isolated, and this volume shows how frequent were his trips to London and further afield, how regular his meetings with his scientific colleagues, and how extensive his network of correspondents.

With the increasing application of software in systems, especially safety- or even life-critical systems, it is no longer sufficient for the software developer to rely solely on testing the code produced. Testing must begin with the specification of requirements, continue on the design and finally on the implemented system. This book gives guidance on how testing can be carried out at each of the stages of software development. It does this by looking at the development process from four viewpoints: that of the intended user of the system, of its designers, of its programmers, and of the manager responsible for development. The product of each stage of development is individually examined to see how it can be checked for correctness and consistency with earlier specifications. References are given to techniques available to the software developer and there are many helpful checklists. The contributors are all members of the British Computer Society's Working Group on Testing, and betwe

When this book was first published in 1984, the technique of remote sounding was growing rapidly in importance as a means for studying the structure, climate and weather of the atmospheres of the Earth and planets. Measurements from Earth satellites and interplanetary spacecraft proved particularly useful because they allowed good coverage of atmospheric systems in space and time, often with high resolution. This book describes how measurements can be made of the properties of the Earth and planets using this method. It includes descriptions of the scientific principles, technical implementation, mathematical methods for analysing the measurements, a history of measurements that have been made and discussions of the phenomena that have been discovered and studied using remote sounding. The technique is important for meteorology, climatology and an understanding of humankind's impact on the Earth's atmosphere.

A sound knowledge of biology, mathematics, physics and chemistry in needed to understand how excitable cells function and the many basic concepts involved in acquiring this knowledge are described from first principles in this book. As these principles equally apply to other biological fields such as the study of membrane transport, artificial membranes, signal capturing, analysis in biological systems and general applications of mathematics and physics to biology, they are of general interest. An important feature of the book is the appendices, in which mathematical functions are derived, and which ensure the usefulness of the volume as a reference manual.

A guide for racing covers the principles of sail trim, crew movement techniques, maneuvers, and control systems, and gives advice on adjusting to special conditions.

Chemical reaction engineering has as its objective the taking of desired reaction processes from the laboratory to the full-scale production plant. From its early roots in applied chemistry, it started expanding in the 1950s, since when there has been a substantial growth of the subject as a result of much research in universities and industry. In this 1984 third edition of their established textbook, Professors Denbigh and Turner present a fascinating account of the subject, reflecting these changes. The authors have retained their primary aim of giving the reader a sense of orientation within the subject. The design and operation of industrial reactors nowadays requires computer skills, but such computation must be based on a firm grasp of the principles of chemical reaction engineering. The text was written primarily for undergraduate students of chemical engineering, however, there are selections of references enabling all interested readers to find their way into the literature.

BCPL is a simple systems programming language with a portable compiler that has been implemented on many machines from large mainframes to mini computers and microprocessors. The book provides an introduction to the language, paying particular attention to programming style. In addition, it covers the more machine-independent parts of the BCPL library and outlines various debugging aids that most implementations provide. The syntax analysis phase of the compiler is described in detail, giving a realistic example of a typical application of the language. This and other substantial examples given in the book will be of interest both to serious users of BCPL and to computer writers. There is a chapter concerned with the portability code generator design. The reference for BCPL appears as the final chapter.

This is a reprint of the second edition of Dr Rayner's standard text on the stratigraphy and historical geology of the British Isles. The book is written for undergraduates and other readers who may have only a general acquaintance with the broad principles of geology. An introductory chapter reviews the basic principles of stratigraphy, geochronology and tectonics. The various geological systems found in the British Isles are then considered in turn. A valuable feature of the book is the extensive treatment of different regional areas within the discussion of a particular geological system. In the final chapter the author reviews briefly those major economic resources that are related to stratigraphy. Throughout the text care has been taken to introduce the plate tectonic interpretation of stratigraphic features. Much more is known about the neighbouring continental shelf and the geology of sea floors and this also is included in order to provide a comprehensive integrated account of

This book was originally published in 1980. Owing to the increasing use of electronic instrumentation in medical practice it was desirable that medical and nursing personnel have some technical knowledge of electronic equipment. It was the aim of this volume to help those members of the medical profession to develop this knowledge. The reader will find a survey of basic principles and methods, with illustrations of the applications in the most common fields of medical practice, for instance the registration of cardiac activity by means of the ECG. More complicated instrumental systems, such as those used for intensive care, are discussed in the light of the basic principles. These include acquaintance with three important concept in electricity: voltage, current and resistance.

This handbook is designed for experimental scientists, particularly those in the life sciences. It is for the non-specialist, and although it assumes only a little knowledge of statistics and mathematics, those with a deeper understanding will also find it useful. The book is directed at the scientist who wishes to solve his numerical and statistical problems on a programmable calculator, mini-computer or interactive terminal. The volume is also useful for the user of full-scale computer systems in that it describes how the large computer solves numerical and statistical problems. The book is divided into three parts. Part I deals with numerical techniques and Part II with statistical techniques. Part III is devoted to the method of least squares which can be regarded as both a statistical and numerical method. The handbook shows clearly how each calculation is performed. Each technique is illustrated by at least one example and there are worked examples and exercises throughout the vo

First published in 1979, this volume presents an elementary and, as far as is practicable, non-mathematical introduction to radiation dosimetry. Where it proved necessary to use mathematical notation, it was kept to a simple level. The volume treats dosimetry from first principles, dealing with the interaction of the various radiations with matter, then defining dosimetric quantities and units and showing how the more important ones are measured. It concludes with a brief chapter on radiation protection. Although a number of dosimetric systems are described in some detail the treatment is by no means encyclopaedic. SI units appear throughout, including some which were not yet in universal use when the book was first published. Where it was considered necessary, the older non-SI units were also defined and conversion factors were given.

The experience of the Economic Advisory Council provides the relevant policy background to the Keynesian revolution in economic theory, and to the adoption of the principles of economic management in Britain during the Second World War. This study of this pioneering advisory institution against the inter-war setting of depression, financial crisis and recovery is based on government records, supplemented by other contemporary sources. The book deals with the political and economic origins of the E.A.C. in the post-1918 decade; the role of the Council and its committees of inquiry as the world slump began to make an impact on an already depressed British economy; and the part played by individual economic advisers in the dramatic events which led to the fall of the second Labour Government and Britain's departure from the gold standard in 1931. Throughout the nineteenthirties the work of the Council was carried on by the Committee on Economic Information, which helped to provide the Nat
