The scientific and technological importance of lasers has generated great interest in the field of cavity nonlinear optics. This book provides a thorough description of this subject in terms of modern dynamical systems theory. Throughout, the emphasis is on deriving analytical results and highlighting their physical significance. The early chapters introduce the physical models for active and passive cavities. In later chapters, these are applied to a variety of problems in laser theory, optical bistability and parametric oscillators. Subjects covered include scaling laws, Hopf bifurcations, passive Q-switching, and Turing instabilities. Several of the topics treated cannot be found in other books, including swept control parameter dynamics, laser stability, multimode rate equations, and antiphase dynamics. The book stresses the connections between theoretical work and actual experimental results, and will be of great interest to graduate students and researchers in theoretical physics

The thesis of this original and provocative book is that representative government should be understood as a combination of democratic and undemocratic, aristocratic elements. Professor Manin challenges the conventional view that representative democracy is no more than an indirect form of government by the people, in which citizens elect representatives only because they cannot assemble and govern in person. The argument is developed by examining the historical moments when the present institutional arrangements were chosen from among the then available alternatives. Professor Manin reminds us that while today representative institutions and democracy appear as virtually indistinguishable, when representative government was first established in Europe and America, it was designed in opposition to democracy proper. Drawing on the procedures used in earlier republican systems, from classical Athens to Renaissance Florence, in order to highlight the alternatives that were forsaken, Mani

This compelling book contains a comprehensive analytical treatment of the theory of production in a long-period framework. Although the authors take a 'Classical' approach to their subject, the scope of investigation and methods employed should interest all economic theorists. Professors Kurz and Salvadori explore economic systems that are characterised by a particular kind of primary input in the production process, such as different kinds of labour and natural resources. These systems and the corresponding prices can be understood to reflect characteristic features of a capitalist market economy in an ideal way: they express the pure logic of the relationship between value and distribution in an economic system. Specific chapters deal with prices and income distribution, economic growth, joint production, fixed capital, scarce natural resources (both renewable and exhaustible), and heterogeneous labour. The historical origins of the concepts used are also discussed in considerable de

State-space methods form the basis of modern control theory. This graduate text is devoted to a description of these methods in the analysis of linear multi-input, multi-output dynamic systems. Following a chapter which sets out the basic concepts and definitions, state equations of finite dimensional systems, and their solution, are discussed in detail. The principles of time-domain and frequency-domain analysis are then presented, as are the properties and applications of the Z-transformation. Separate chapters deal with the controllability, observability, and stability of linear systems. A useful tutorial review of the key results from matrix theory and linear algebra is given in the appendix. The book includes several worked examples, and there are problems at the end of each chapter. It will be of great use to advanced undergraduate and graduate students of electrical or mechanical engineering taking courses in linear systems or control systems.

The theory of pattern formation, assumed to be applicable to all multicellular organisms, has been developed largely through the study of animal, and to a lesser extent, plant systems. Fungi, members of the third major kingdom of eukaryotes, have not featured in these studies, although much research of fungal morphology has been undertaken with taxonomic intentions. This first account of the developmental biology of fungal morphogenesis considers whether evidence exists for the action of pattern forming mechanisms in the development of fungal structures. Chapters on the fruit body, on a range of aspects of the hyphae and the mycelium, and on genetic control and nuclear events in morphogenesis provide insights into the mechanisms used in fungal construction. Aimed at developmental biologists as well as mycologists, the terminology has been kept as simple as possible to make the volume accessible to the widest audience.

This book, first published in 1996, is a concise yet fully informative coverage of the structure and function of genes. It describes DNA and how it replicates, how DNA is transcribed and translated into proteins, the organisation of genes in prokaryotes and eukaryotes, the control of gene expression and the role of retroviruses and oncogenes in cancer. There are additional discussions of gene families, genes and the immune systems and mitochondrial and chloroplast genomes. This is a third edition of a successful undergraduate text. It has been extensively updated, particularly in regard to advances in our understanding of replication and transcription.

Parasites cause many important diseases in humans and domestic animals, malaria being an example. Parasites have evolved to exploit hosts' bodies whereas hosts have evolved immune systems to control infections. Host-parasite interactions therefore provide fascinating examples of evolutionary 'arms-races' in which the immune system plays a key role. Modern research in immunoparasitology is directed towards understanding and exploiting the capacity to develop effective anti-parasite immunity. By concentrating on selected infections where research has made significant progress, Immunity to Parasites provides a clear account of how host immune responses operate and how parasites can evade immunity. The experimental basis of this research is emphasised throughout. This completely updated second edition includes an expanded section on anti-parasite vaccines. The text is aimed at undergraduates and postgraduates with interests in either parasitology or immunology and provides introductory sec

Since the time of Lagrange and Euler, it has been well known that an understanding of algebraic curves can illuminate the picture of rigid bodies provided by classical mechanics. A modern view of the role played by algebraic geometry has been established iby many mathematicians. This book presents some of these techniques, which fall within the orbit of finite dimensional integrable systems. The main body of the text presents a rich assortment of methods and ideas from algebraic geometry prompted by classical mechanics, whilst in appendices the general, abstract theory is described. The methods are given a topological application to the study of Liouville tori and their bifurcations. The book is based on courses for graduate students given by the author at Strasbourg University but the wealth of original ideas will make it also appeal to researchers.

As software systems become increasingly large and complex, the need increases to predict and control the effects of software changes. This book captures the latest information on the science and art o

The classical theory of dynamical systems has tended to concentrate on Z-actions or R-actions. However in recent years there has been considerable progress in the study of higher dimensional actions (i.e. Zd or Rd with d>1). This book represents the proceedings of the 1993–4 Warwick Symposium on Zd actions. It comprises a mixture of surveys and original articles that span many of the diverse facets of the subject, including important connections with statistical mechanics, number theory and algebra. Researchers in ergodic theory and related fields will find that this book is an invaluable resource.

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.

The main objective of the authors is to deliver specifications and underlying concepts for future computer-aided tools for the design and the control of flexible manufacturing systems for mechanical a

This book is devoted to some mathematical methods that arise in two domains of artificial intelligence: neural networks and qualitative physics. Professor Aubin makes use of control and viability theory in neural networks and cognitive systems, regarded as dynamical systems controlled by synaptic matrices, and set-valued analysis that plays a natural and crucial role in qualitative analysis and simulation. This allows many examples of neural networks to be presented in a unified way. In addition, several results on the control of linear and nonlinear systems are used to obtain a 'learning algorithm' of pattern classification problems, such as the back-propagation formula, as well as learning algorithms of feedback regulation laws of solutions to control systems subject to state constraints. This book will be of value to anyone with an interest in neural networks and cognitive systems.

This textbook for beginning graduate students is a general introduction to the dynamics of astrophysical fluids for students with a knowledge of basic physics at undergraduate level. No previous knowledge of fluid dynamics or astrophysics is required because the author develops all new concepts in context. The first four chapters cover classical fluids, relativistic fluids, photon fluids and plasma fluids, with many cosmic examples being included. The remaining six chapters deal with astrophysical applications: stars, stellar systems, astrophysical plasmas, cosmological applications and large scale structure of the Universe. Astrophysical fluid dynamics is a promising branch of astronomy, with wide applicability. This textbook considers the role of plasma and magnetism in planets, stars, galaxies, the interplanetary, interstellar and intergalactic media, as well as the universe at large.

This compelling book, first published in 1996, is an exploration of the imaginary of perceptual control technologies at the beginning of the twenty-first century. William Bogard constructs a 'social science fiction' of how the revolution in simulation technology reconfigures and intensifies the role of surveillance in war, work, sexuality and private life, enabling forms of control which hyper realise our experience of time, space, agency and society itself. His is a critique of the imaginary in which control breaks free of its prior limits, an imaginary of unmediated perception with effects everywhere in fantastic systems for the relentless conversion of objects, events and people into information.

This book presents the newly developed theory of non-harmonic Fourier series and its applications to the control of distributed parameter systems. The authors extend the theory to include vector exponential series. The first part of the book presents the modern theory of exponentials, using an operator theory approach. The second part of the book extends and upgrades the method of moments - one of the most powerful tools in the flourishing theory of the control of distributed parameter systems. The book then goes on to discuss the controllability of systems described by parabolic and hyperbolic PDEs for internal, boundary, initial, and pointwise control. Typical applications to optimal control problems are also considered. Researchers in control theory, operator theory, functional analysis and partial differential equations will find much to interest them in this treatise.

This text covers the field of steady-state kinetics from basic principles to the control of the multi-enzyme systems which constitute metabolic pathways. Emphasis is placed on the interpretation of the kinetic behaviour of enzyme-catalyzed reactions in terms of mechanisms. Algorithms are developed which can be implemented in computer programs for the derivation of equations. The treatment of steady-state enzyme kinetics is extended to allosteric enzymes and subunit interactions in polymeric enzymes. Principles are presented which provide for mathematical analysis of the control of multi-enzyme systems. Problems are included at the end of each chapter and their solutions are found at the end of the book. This book will be a useful text for advanced undergraduates and graduate students taking courses in enzyme chemistry and enzyme kinetics.

This is a self-contained introduction to the classical theory of homoclinic bifurcation theory, as well as its generalizations and more recent extensions to higher dimensions. It is also intended to stimulate new developments, relating the theory of fractal dimensions to bifurcations, and concerning homoclinic bifurcations as generators of chaotic dynamics. To this end the authors finish the book with an account of recent research and point out future prospects. The book begins with a review chapter giving background material on hyperbolic dynamical systems. The next three chapters give a detailed treatment of a number of examples, Smale's description of the dynamical consequences of transverse homoclinic orbits and a discussion of the subordinate bifurcations that accompany homoclinic bifurcations, including Hénon-like families. The core of the work is the investigation of the interplay between homoclinic tangencies and non-trivial basic sets. The fractal dimensions of these basic set
