Classical Control Systems

A comprehensive and extensive study of the latest research in control systems for marine vehicles. Demonstrates how the implementation of mathematical models and modern control theory can reduce fuel

Almost all the many past studies on chaos have been concerned with classical systems. This book, however, is one of the first to deal with quantum chaos, the natural progression from such classical systems. In this book the author deals with three major issues in quantum chaos. First, quantum mechanics is applied to both bounded and open systems exhibiting classical chaos. Potential problems involving quantum chaos are revealed in diverse areas of solid-state science, and standard concepts such as diamagnetism, antiferromagnetism, spin waves, electrical conductance and so on are shown in a fresh light through quantum chaos. Second, adiabatic-ansatz eigenvalue problems are shown to yield a new paradigm of non-linear dynamics, closing the gap between the greatly different theories of solitons and random matrices. Finally, the author provides a clue to how quantum mechanics may be improved so as to accommodate temporal chaos. First published in 1993, this book will be of value to researc

Using a systems perspective, this updated version concentrates on the planning, scheduling and control factors of a project needed to bring it in on time and on or under cost. This edition contains ex

Centering on the examination of the social and legal context of adultery, homosexuality, impiety, and the public-private dichotomy in Athenian society, this book attempts to examine the problems of social control and the regulation of sexuality in a way that will be of interest to a broad readership. It uses a comparative approach to show how the examination of such issues can deepen our understanding of classical Athens, particularly in regard to the role of law in society. Further, it argues that this historical investigation can, in turn, enrich our general appreciation of the relation of social and legal norms, and the roles they play in regulating complex social practices, such as those associated with sexuality, morals and the family.

This book brings different ideas to bear on the classical problem of the self. Self-perception, both ecological and social, is the earliest and most fundamental form of self-knowledge. In his introduction, Ulric Neisser describes the 'ecological self' as based on direct and realistic perception of one's situation in the environment; the 'interpersonal self' as established by social interaction with other people. He argues that both of these 'selves' appear in early infancy, long before anything like a self-concept or a self-narrative is possible. In subsequent chapters, fifteen contributors - psychologists, philosophers and others - elaborate on these notions and introduce related ideas of their own. Their topics range from the perceptual and social development of infants to autism and blindness; from mechanisms of motor control to dance and non-verbal communication. The combined contributions of these leading individuals creates an unusual synthesis of perceptual, social and developme

Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The specific spatial pattern of riparian vegetation is seen as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. Riparian structures are controlled by the spatial dynamics of channels, flooding and soil moisture. These dynamics are part of integrated cascades of water, sediment, nutrients and carbon, to which animal and plant species respond in ways that illuminate community structure and competition. The role of the riparian zone in controlling species distribution and abundance is discussed. Intelligent management of these valuable ecological resources is highlighted. The potential for linking hydrological, geomorphological and ecological simulation models is also explored.

This 1992 book examines alternative methods for achieving optimality without all the apparatus of economic planning (such as information retrieval, computation of solutions, and separate implementation systems), or a vain reliance on sufficiently 'perfect' competition. All rely entirely on the self-interest of economic agents and voluntary contract. The author considers methods involving feedback iterative controls which require the prior selection of a 'criterion function', but no prior calculation of optimal quantities. The target is adjusted as the results for each step become data for the criterion function. Implementation is built in by the incentive structure, and all controls rely on consistency with the self-interest of individuals. The applicability of all the methods is shown to be independent of the form of ownership of enterprises: examples are given for industries which are wholly privately owned, wholly nationalized, mixed and labour-managed.

The practice of growing two or more crops together is widespread throughout the tropics and is becoming increasingly practised in temperate agriculture. The benefits of nutrient exchange, reduced weed competition and pathogen control can generate substantial improvements in growth and yield. In this book John Vandermeer, a leading worker on the subject, shows how classical ecological principles, especially those relating to competition and population ecology, can be applied to intercropping. Despite the large amount of research activity directed towards the subject over the last 20 years, the practice of intercropping has, until now, received very little serious academic attention. The Ecology of Intercropping is unique in approaching the question of intercropping from a theoretical point of view. In addition the details of the approach will take as their starting point well-accepted ecological theory. Using this basis the author shows how the approach can be used to design and evaluat

The use of geometric methods in classical mechanics has proven to be a fruitful exercise, with the results being of wide application to physics and engineering. Here Professor Marsden concentrates on these geometric aspects, and especially on symmetry techniques. The main points he covers are: the stability of relative equilibria, which is analyzed using the block diagonalization technique; geometric phases, studied using the reduction and reconstruction technique; and bifurcation of relative equilibria and chaos in mechanical systems. A unifying theme for these points is provided by reduction theory, the associated mechanical connection and techniques from dynamical systems. These methods can be applied to many control and stabilization situations, and this is illustrated using rigid bodies with internal rotors, and the use of geometric phases in mechanical systems. To illustrate the above ideas and the power of geometric arguments, the author studies a variety of specific systems, in

This book provides a comprehensive account of the proteins involved in blood coagulation, fibrinolysis and the complement system. A major section of the book is devoted to each of these three systems, with separate chapters dealing in detail with structural aspects and different functional processes. Topics covered in the blood coagulation section include the activation of factors IX and X and prothrombin, and the formation and stabilisation of fibrin. The fibrinolysis section includes the activation of plasminogen, the degradation of fibrin and the regulation of fibrinolysis. The complement system itself is covered in chapters dealing with classical activation, alternative activation, the lytic complex and the regulatory processes involved. In addition, one section deals with special topics, including the kinin system, signal peptides, haemostasis, and the evolution of protein structure. This volume will be of use to researchers and advanced students in the fields of haematology, immu

This 1991 study deals with a specific set of institutions in nineteenth-century Athens. Relying on matrimonial contracts, travellers' accounts, memoirs and popular literature, the authors show how distinctive forms of marriage, kinship and property transmission evolved in Athens in the nineteenth century. These forms then became a feature of wider Greek society which continued into the twentieth century. Greece was the first post-colonial modern nation state in Europe whose national identity was created largely by peasants who had migrated to the city. As Athenian society became less agrarian, a new mercantile group superseded and incorporated previous elites and went on to dominate and control the new resources of the nation state. Such groups developed their own, more mobile, systems of property transmission, mostly in response to external pressures of a political and economic character. This is a persuasive piece of detective work which has advanced our knowledge of modern Greece. I

Originally published in 1990, this text brings together a detailed review by acknowledged authorities of grass reproductive biology. Grasses are our most important plants whether for agriculture or conservation. Essential to contemporary awareness of grasses is an understanding of their role in sustaining ecologically fragile environments, and the relative importance of annual and perennial reproduction is examined here with particular reference to indigenous dryland grasses marginal to major deserts. Molecular biology and tissue culture allow us to intervene in reproductive systems and the issues include a fundamental revision of the concept of double fertilisation grass pollen in relation to human allergy and the prospects for developing wheat male sterility. The book concludes with an overview to assess how far evolution of the grass is coming under human control.

The application of molecular biological techniques to the study of development has had a profound effect on our understanding of developmental processes. This 1985 book expounds some of the views on which hierarchies of genes control aspects of animal development. There is an emphasis on the best-studied systems, namely Drosophila and the nematode Caenorhabditis, though some features of mouse and sea-urchin development are also discussed. The book focuses on how information obtained from the study of mutants, combined with molecular details of the structure, regulation and functions of the genes involved, sheds light on the complex processes of animal development. The 1990 second edition, which is reprinted here, is an expanded and largely rewritten version of Dr de Pomerai's successful first edition. It features extensive additions to the chapter on insect development, a chapter discussing nematode development and another addressing differentiation in vertebrate systems.

Illustrates the use of systems such as in-process control, quality auditing, and specifications, stressing a troubleshooting, cost-effective approach to product packaging for maximized early lead time

This introduction to the theory of Hamiltonian chaos outlines the main results in the field, and goes on to consider implications for quantum mechanics. The study of nonlinear dynamics, and in particular of chaotic systems, is one of the fastest growing and most productive areas in physics and applied mathematics. In its first six chapters, this timely book introduces the theory of classical Hamiltonian systems. The aim is not to be comprehensive but, rather, to provide a mathematical trunk from which the reader will be able to branch out. The main focus is on periodic orbits and their neighbourhood, as this approach is especially suitable as an introduction to the implications of the theory of chaos in quantum mechanics, which are discussed in the last three chapters.

An important research programme has developed in economics that extends neo-classical economic theory in order to examine the effects of institutions on economic behaviour. The body of work emerging from this line of inquiry includes contributions from various branches of economic theory, such as the economics of property rights, the theory of the firm, cliometrics and law and economics. This book is a comprehensive survey of this research programme which the author terms 'neoinstitutional economics'. The author proposes a unified approach to this research, integrating the work of various contributors and emphasising the common principles of inquiry that tie the work together. The theoretical discussion is accompanied by empirical studies dealing with a range of institutions and economic systems. This book will serve as the primary resource for economists and students who want to learn about this important branch of economic theory.

Meiosis, the antithesis of fertilization, is the unique genetically programmed mode of nuclear division associated with a halving of the chromosome number in sexually reproducing eukaryotes. It thus represents a key cellular and developmental pathway in the life of an organism. In this book, Bernard John presents the first complete, and the most authoritative, review of the events and mechanisms of meiosis including their scheduling, their mechanics and their biochemistry as well as their genetic control and the variations to be found in them in both sexual and subsexual systems. The text is superbly illustrated with 131 figures and 73 tables. Meiosis must be regarded as essential reading for all students, teachers and research workers with an interest in eukaryotic cell biology and genetics.

This book presents a coherent and systematic exposition of the mathematical theory of the problems of optimization and stability. Both of these are topics central to economic analysis since the latter is so much concerned with the optimizing behaviour of economic agents and the stability of the interaction processes to which this gives rise. The topics covered include convexity, mathematical programming, fixed point theorems, comparative static analysis and duality, the stability of dynamic systems, the calculus of variations and optimal control theory. The authors present a more detailed and wide-ranging discussion of these topics than is to be found in the few books which attempt a similar coverage. Although the text deals with fairly advanced material, the mathematical prerequisites are minimised by the inclusion of an integrated mathematical review designed to make the text self-contained and accessible to the reader with only an elementary knowledge of calculus and linear algebra.

This book sets out a generative structuralist conception of general theoretical sociology; its philosophy, its problems, and its methods. The field is defined as a comprehensive research tradition with many intersecting subtraditions that share conceptual components. The focus is on formalization and unification as processes that can help advance the state of theory today. An integrative philosophy of the field is set out in terms of a process worldview, with a focus on generativity in explanation and a conception of the structure of theories as hierarchical meaning control systems. This philosophy is implemented in two phases. In the first phase, Professor Fararo defines the core problems of theoretical sociology in the context of setting out and illustrating the logic of a nonlinear dynamical social systems framework. A critical analysis of the outcome of this phase then leads, in the second phase, to formal treatments of action principles and structural analysis. A variety of tradit

The collection consists of four parts: Part I presents three non-technical essays on economic development and economic systems. Four out of five essays in Part II deal with the theory and measurement of the so-called Index of Total Factor Productivity for several countries. The fifth essay is on the theory of index numbers. The first essay of Part III compares the American and Soviet patterns of economic development and finds that the path followed by each country might have been optimal for it at the time. The second essay develops a general theory of a producer cooperative. The third essay discusses a method for avoiding monopolistic exploitation, under either system, without price control. Part IV presents three applications of economic theory to historical problems - in particular, to serfdom and slavery. The first, on 'The Causes of Slavery or Serfdom', has become a classic. The second challenges the widely accepted view that Russian serfdom had become unprofitable for the serf-ow

Control of office has long been regarded as the key element in understanding power and policy in the Soviet system. What, however, accounts for the control of office and how are individuals recruited into positions of power and responsibility? In An Algebra of Soviet Power, Michael Urban adopts a fresh approach and introduces into the field of political elite studies the sociological technique of vacancy chain analysis. This treats the movements of actors as sequences of complex inter-relations that are structured by the properties and powers of the personnel system rather than by the consequences of individual intentions or characteristics. This algebraic method is applied to a large body of career data of officials from the Soviet Republic of Belorussia for the period 1966–86. The author documents how, despite the formal systems of nomenklatura - central control over personnel placement - the flow of individuals through the hierarchy of offices in Belorussia has not been influenced b

The book describes the biological ways in which diseases of plants, caused by pathogenic microbes, can be controlled without the use of chemical pesticides. The basis of biocontrol (in microbiology, ecology and plant pathology) is described and many examples of control measures in commercial use or development are given. There is increasing interest in biocontrol from the general public, environmentalists and the major world agrochemical companies, and this easily read text presents recent developments in the subject. The book provides enough references and literature citations to allow a more detailed investigation of particular diseases or control systems to be made. This textbook is suitable for graduate and undergraduate students in botany, biology, microbiology, plant pathology, agriculture, horticulture, crop science, microbial ecology, crop protection and related courses.

The rational expectations revolution and other developments in economics (notably game theory) have fundamentally altered the application of optimal control theory to economic forecasting and planning. In particular, they have shown that economic systems cannot be modelled simplistically on physical systems. However, as the authors of this volume show, these developments have greatly enhanced our understanding of how an economy functions, and now make it possible for optimal control theory to be applied much more effectively to economic modelling and planning. This book is divided into two parts. The first presents the orthodox framework but extends it to allow for multiplicative uncertainty, risk and non-linearities in the econometric model. The second part looks explicitly at the question of expectations. It provides methods by which forward-looking expectations can be treated jointly with the determination of economic policy. It also examines game-theoretic considerations - where, f

Law has often been seen as a relatively autonomous domain, one in which a professional elite sharply control the impact of broader social relations and cultural concepts. By contrast this study asserts that the analysis of legal systems, like the analysis of social systems generally, requires an understanding of the concepts and relationships encountered in everyday social life. Using as its substantive base the Islamic law courts of Morocco, the study explores the cultural basis of judicial discretion. From the proposition that in Arabic culture relationships are subject to considerable negotiation the idea is developed that the shaping of facts in a court of law, the use of local experts, and the organization of the judicial structure all contribute to the reliance on local concepts and personnel to inform the range of judicial discretion. By drawing comparisons with the exercise of judicial discretion in America the study demonstrates that cultural concepts deeply inform the evaluat
