Principles of Computer Systems and Network Management

Despite the waves of re-engineering, there is still a gap between the opportunities offered by information technology and the progress of business transformation. New forms of information technology offer an increasing variety of network-based applications that range from groupware to electronic commerce, but its applications lack a sound understanding of the link between organizational processes, information and technology. This book provides a new set of concepts and methods to design new forms of business organizations around the latest network infrastructures. Professor Ciborra uses the principles of institutional economics to propose reforms of the relationships with suppliers, customers, strategic partners, and internal work organisation, based on a different mix of three basic organizational forms: teams, markets and hierarchies. Information technology can indeed be harnessed to shape businesses and markets so as to increase the transparency of markets, the agility of hierarchie

This 1996 book is a greatly expanded edition of what has become one of the best known introductions to the principles, techniques and applications of optical holography. Where necessary, existing sections have been updated, and two new chapters have been added. After presenting the theory of holographic imaging and the various types of holograms, practical aspects of holography are then covered, as are the production of holograms for display, colour holography and computer generated holograms. A variety of the applications of holography are then discussed in detail, such as high resolution imaging, information storage and processing, vibration analysis, and holographic interferometry. Containing more than 1000 selected references, this book will be invaluable to anyone wishing to learn more about optical holography, as well as to established researchers and engineers in this field.

This book is about abduction, 'the logic of Sherlock Holmes', and about how some kinds of abductive reasoning can be programmed in a computer. The work brings together Artificial Intelligence and philosophy of science and is rich with implications for other areas such as, psychology, medical informatics, and linguistics. It also has subtle implications for evidence evaluation in areas such as accident investigation, confirmation of scientific theories, law, diagnosis, and financial auditing. The book is about certainty and the logico-computational foundations of knowledge; it is about inference in perception, reasoning strategies, and building expert systems.

Industrial Democracy in America begins its close examination of what came to be known among collars of any colour as 'the labour problem' with the railroad strikes of the 1870s. The contributors cover the theory and practice of the American labour movement, the promise and demise of industrial jurisprudence, the law of collective bargaining, workplace contractualism, and shop-floor reality in the United States auto industry, and compare these with employment systems in Japan. This book contemplates America's industrial decline and will provoke questions, even within management circles, of the long-run viability of a work regime that does not respect or motivate its workers.

Recent and ongoing developments in science and technology - such as the prevention and treatment of disease through genetics and the development of increasingly sophisticated computer systems with wide-ranging applications - hold out the promise of vastly improving the quality of human life, but they can also raise serious ethical, legal, and public policy questions. The thirteen essays in this volume address these questions and related issues from a variety of perspectives. Written by prominent philosophers, economists, and legal theorists, these essays offer valuable insights into the nature of scientific innovation and its implications for our social policies and practices.

Cell therapy is a rapidly developing area, drawing on cell biology, molecular biology, virology, immunology, cell quantitation techniques and biomedical engineering. It has potential in many clinical settings, in the treatment of cancer and other diseases. This volume in the series Cancer: Clinical Science in Practice examines the current state and future prospects of cell therapy, which seems likely to have an even more profound impact on health care than did the production of proteins by recombinant DNA technology. The coverage is broad, including the scientific principles of haematopoietic cell therapy, the technology of cell collection and preparation, current and likely future clinical applications of cell therapy, and the principles and practice of cellular immunotherapy. Up-to-date and authoritative, volumes in this series are intended for a wide audience of clinicians and researchers with an interest in the applications of biomedical science to the understanding and management

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 theory of short optical pulse generation by modelocking is covered in the first chapter. Thereafter, modelocking techniques in different types of lasers are discussed: solid state lasers; diode-pumped lasers; fiber lasers; surface emitting semiconductor lasers; external cavity semiconductor lasers; hybrid soliton pulse sources; and monolithic colliding pulse modelocked diode lasers. Presenting both theoretical and experimental aspects throughout, this book will be invaluable to anyone interested in short pulse laser systems, and particularly to researchers involved in high-speed communications or the investigation of ultrafast phenomena.

The Conservation of Plant Biodiversity highlights the different levels of biological organisation at which conservation is being addressed - the gene, the species and the community. Conservation biology is faced with several controversial issues such as the dichotomy between the preservation of individual species versus a broader focus on the environment, the relative importance to give to endangered species, the design and management of reserves and the drive for increasing agricultural productivity through plant improvement versus the drive to maintain traditional peasant varieties in cultivation. These and other issues are dealt with here by emphasising and exploring the underlying scientific principles. The conservation of whole communities emerges as the paramount strategy for maintaining the evolutionary potential of plant life.

The U.S. has generally tried to discourage its allies from developing their own major weapons systems, to promote equipment standardization with U.S. forces, and tie allied security policies more firm

Winds over topography and inside forests produce mechanical reactions in trees, and eventually failure in stems and roots when stressed by storms. The mechanics of these reactions and the physiological responses to wind in leaves, stems and root systems, and the important ecological consequences of wind-throw are described in this book. Management techniques of forests in windy climates are detailed, including the use of models predicting risk of wind damage. It is clear that the whole field of wind effects on trees has benefited from recent multi-disciplinary research, and significant advances in knowledge of most parts of the subject have been made in the last decade. This book brings the up-to-date theories, methodologies and results together, and gives the reader a sense of coherence in this complex but fascinating field.

Optical techniques have a huge range of potential applications in signal processing and in the interconnection of digital computing systems. This 1995 book provides a detailed review of the key issues which must be addressed in the design, evaluation and implementation of practical systems for signal processing and optical interconnection. Considerations such as the computer modelling of optical design limitations, the size and noise characteristics of optical modulators, and the relative merits of free-space and guided-wave optical technology in different processing systems, are all discussed in detail. The book will be of great interest to optical researchers and designers, and to anyone wishing to learn about the basic techniques of optical processing.

Schemas in Problem Solving explores a theory of schema development and studies the applicability of the theory as a unified basis for understanding learning, instruction and assessment. The theory's prescriptions for teaching are direct, and its application to assessment suggests new directions for tests. After examining the roots of the theory in earlier work by philosophers and psychologists, Marshall illustrates the main features of her theory with experimental evidence from students who are learning to recognize and solve arithmetic story problems. She describes individual performance with traditional empirical studies as well as computer simulation. The computer simulation reflects an approach in modelling cognition. Marshall's model links neural networks with symbolic systems to form a hybrid model that uses pattern matching of sets of features as well as logical step-by-step rules.

This book is an up-to-date introduction to the quantum theory of measurement, a fast developing field of intense current interest to scientists and engineers for its potential high technology applications. It is also a subject of importance to students for its central role in the foundations of quantum mechanics. Although the main principles of the field were elaborated in the 1930s by Bohr, Schrödinger, Heisenberg, von Neumann and Mandelstam, it was not until the 1980s that technology became sufficiently advanced to allow its application in real experiments. Quantum measurement is now central to many ultra-high technology developments, such as squeezed light, single atom traps, and searches for gravitational radiation. It is also considered to have great promise for computer science and engineering, particularly for its applications in information processing and transfer. The book contains a pedagogical introduction to the relevant theory written at a level accessible to those with on

Markov chains are an important idea, related to random walks, which crops up widely in applied stochastic analysis. They are used, for example, in performance modelling and evaluation of computer networks, queuing networks, and telecommunication systems. The main point of the present book is to provide methods, based on the construction of Lyapunov functions, of determining when a Markov chain is ergodic, null recurrent, or transient. These methods can also be extended to the study of questions of stability. Of particular concern are reflected random walks and reflected Brownian motion. The authors provide not only a self-contained introduction to the theory but also details of how the required Lyapunov functions are constructed in various situations.

This is a first course in propositional modal logic, suitable for mathematicians, computer scientists and philosophers. Emphasis is placed on semantic aspects, in the form of labelled transition structures, rather than on proof theory. The book covers all the basic material - propositional languages, semantics and correspondence results, proof systems and completeness results - as well as some topics not usually covered in a modal logic course. It is written from a mathematical standpoint. To help the reader, the material is covered in short chapters, each concentrating on one topic. These are arranged into five parts, each with a common theme. An important feature of the book is the many exercises and an extensive set of solutions is provided.

This book sets out the principles of parallel computing in a way which will be useful to student and potential user alike. It includes coverage of both conventional and neural computers. The content of the book is arranged hierarchically. It explains why, where and how parallel computing is used; the fundamental paradigms employed in the field; how systems are programmed or trained; technical aspects including connectivity and processing element complexity; and how system performance is estimated (and why doing so is difficult). The penultimate chapter of the book comprises a set of case studies of archetypal parallel computers, each study written by an individual closely connected with the system in question. The final chapter correlates the various aspects of parallel computing into a taxonomy of systems.

Human Computer Interaction (HCI) is concerned with every aspect of the relationship between computers and people (individuals, groups and society). The annual meeting of the British Computer Society's HCI group is recognised as one of the main venues for discussing recent trends and issues. This volume contains refereed papers and reports from the 1994 meeting. A broad range of HCI related topics are covered, including interactive systems development, user interface design, user modelling, tools, hypertext and CSCW. Both research and commercial perspectives are considered, making the book essential for all researchers, designers and manufacturers who need to keep abreast of developments in HCI.

Comparable worth, or pay equity, is now an established policy in some US states, such as Minnesota, and the UK and Australia. Yet Steven Rhoads's research on those jurisdictions indicates there is no consensus on how to compare the value of dissimilar jobs involving 'comparable' amounts of effort, skill and responsibility. Consultants whose job evaluation systems are used in states adopting comparable worth policies do not agree on the factors to be included or how they should be weighed and arbitrary results produced by comparable worth policies have led to inefficient functioning of the labour markets. These policies have generated ill will among the workers who lose pay-equity cases, with political as well as economic consequences. The book argues that jobs are truly incomparable using the methods comparable worth relies on, and that the principles of comparable worth are not reconcilable with those of a market economy.

Phyllotaxis, the study of the patterns exhibited by leaves and other organs of plants, raises some of the deepest questions of plant morphogenesis. What principles of biological organisation produce these dynamical geometric systems? The constant occurrence of the Fibonacci sequence in such systems is a phenomenon that has fascinated botanists and mathematicians for centuries. In this book, first published in 1994, the many facets of phyllotaxis are dealt with in an integrated manner for the first time. The author describes a unified concept of phyllotaxis based on experimental, anatomical, cellular, physiological and paleontological observations. The book provides a framework for formal analyses of botanical data and emphasises the relevance of the phyllotactic paradigm in the study of other structures, such as crystals and proteins. It is of interest to cystallographers and physicists as well as to botanists and mathematicians.

This book provides a brief but thorough account of the basic principles of good pump design. The first three chapters present the basic hydraulic equations, including cavitation, and discuss the principles that underlie the correct performance of the impeller and casing of centrifugal pumps and the blading of axial machines. The fourth chapter outlines analytical methods for flow calculations, including special techniques used in computer aided design. The following two chapters work through two examples: the impeller and casing of a simple volute type centrifugal pump; and an axial flow pump impeller. Shafts, bearings, seals and drives are discussed in a separate chapter. The last two chapters deal with design for difficult fluids, and codes and practices.

This textbook explains the basic principles of categorical type theory and the techniques used to derive categorical semantics for specific type theories. It introduces the reader to ordered set theory, lattices and domains, and this material provides plenty of examples for an introduction to category theory. which covers categories, functors, natural transformations, the Yoneda lemma, cartesian closed categories, limits, adjunctions and indexed categories. Four kinds of formal system are considered in detail, namely algebraic, functional, polymorphic functional, and higher order polymorphic functional type theory. For each of these the categorical semantics are derived and results about the type systems are proved categorically. Issues of soundness and completeness are also considered. Aimed at advanced undergraduates and beginning graduates, this book will be of interest to theoretical computer scientists, logicians and mathematicians specialising in category theory.
