Neuware - This volume contains the proceedings of the IFAC Workshop on Singular Solutions and Perturbations in Control Systems (SSPCS-97) held at Pereslavl-Zalessky, Russia on 7-11 July 1997. The Workshop was sponsored by IFAC and organized jointly by the Russian National Committee of Automatic Control, the Program Systems Institute and the Institute for Information Transmission Problems at the Russian Academy of Sciences, and the University of Pereslavl.The objective of this workshop was to provide an international forum for the discussion of recent developments and advances in the fields of singular control problems, impulsive control, singular perturbations technique in control systems, computational problems and others.The Workshop was devoted both to theoretical and applicative aspects of the so-called 'nonclassical' problems in the area of control theory, such as problems with singular perturbations, impulse and generalized controls. These problems arise in various areas of applications, including mechanics, information processing, medicine and economy. At the same time they stimulate the development of new mathematical tools in the classical theory of control and differential equations.All papers included in this volume are given in the form presented by the authors.…

Buch. Condición: Neu. Neuware - Islamic states the process of definition and the source of legitimacy of public policy is complex and potentially more controversial than in secular states. This complexity arises from applying the interpretations of the divine law, the Shari'a, to contemporary social issues. The Shari'a is the code of social conduct and the means of regulating social discourse as well a social change. fundamental issues arise. First, what is the legitimate source and process of interpretation of the precepts of Islamic law, the Shari'a And second, how are the specific dictums of the Shari'a affected by the fundamental changes in the social and technological circumstances of life to this politico-theological issues. The problem has evolved into the more fundamental questions of what is Islam and whose Islam frequently asked by Muslim revivalists groups themselves, who claim that theirs is the true Islam. practical applications of a major issue in public policy, and with the controversies that may exist on the interpretation of Islamic precepts on the topic. In this respect, this volume is planned to be a cohesive and integrated collection, seeking to reflect the difference in methodological approaches of various authors.…

Buch. Condición: Neu. Neuware - The purpose of the book is to provide a comprehensive overview of hemispheric differences in sensory and perceptual processing. The first section of the book deals directly with the intra- and inter-hemispheric processing of spatial and temporal frequencies in the visual modality. The second section addresses the initial interaction between sensory and cognitive mechanisms, dealing with how the left and right cerebral hemispheres differ in their computation and representation of sensory information. The third section covers how attentional mechanisms modulate the nature of perceptual processing in the cerebral hemispheres. Section four consists of a single chapter which reviews evidence suggesting a functional linkage between upper and right visual field processing, on the one hand, and lower and left visual field processing on the other.…

Buch. Condición: Neu. Neuware - Philosophers have had an interest in language from the earliest times but the twentieth century, with its so-called 'linguistic turn' in philosophy, has seen a huge expansion of work focused specifically on language and its foundations. No branch of philosophy has been unaffected by this shift of emphasis. It is timely at the end of the century to review and assess the vast range of issues that have been developed and debated in this central area.The distinguished international contributors present a clear, accessible guide to the fundamental questions raised by the philosophers about language. Contributions include Graeme Forbes on necessity, Susan Haack on deviant logics, Paul Horwich on truth, Charles Travis on Wittgenstein, L.J. Cohen on linguistic philosophy, Ruth Kempson on semantics and syntax and Christopher Hookway on ontology, to name but a few. A wide range of topics are covered from the metaphysics and ontology of language, language and mind, truth and meaning, to theories or reference, speech act theory, philosophy of logic and formal semantics. There are also articles on key figures from the twentieth century and earlier.Based on the foundation provided by the award-winning Encyclopedia of Language and Linguistics this single volume provides a collection of articles that will be an invaluable reference tool for all those interested in the area of philosophy of language, and also to those in cognitive science and psychology. All the articles have been thoroughly revised and updated. This volume gives a unique survey of topics that are at the very core of contemporary philosophy.…

Buch. Condición: Neu. Neuware - Trace Determination of Pesticides and their Degradation Products in Water is a critical compilation of analytical methods for the monitoring of pesticides and their degradation products in water. It contains up-to-date material and is the result of the authors' experience in the pesticide analysis field. The book is structured in six chapters, starting from general aspects of pesticides like usage, physicochemical parameters and occurrence in the environment. A second chapter is devoted to sampling from water matrices, stability methods of pesticides in water and quality assurance issues. The general chromatographic methods for pesticides are reported, including the newly developed electrophoresis methods and GC-MS and LC-MS confirmatory analytical methods. Sample preparation methodologies, including off-line and on-line techniques are described in the next two chapters, with a comprehensive list of examples of pesticides and many metabolites, including the use of different GC-methods and LC-methods. The final chapter is devoted to the development of biological techniques, immunoassays and biosensors, for the trace determination of pesticides in water samples. …

Buch. Condición: Neu. Neuware - Nuclear Magnetic Resonance Spectroscopy (NMR) is now widely regarded as having evolved into a subscience. The field has become immensely diverse, ranging from medical use through solid state NMR to liquid state applications, with countless books and scientific journals devoted to these topics. Theoretical as well as experimental advance continues to be rapid, and has in fact accelerated by many novel innovations. This multi-authored book focuses on the latest developments in the rapidly evolving field of high resolution NMR, specifically with a view to applications on the structure elucidation of organic molecules of moderate molecular weight. Conceptually it differs from basic educational texts, hard-core scientific papers and regular review articles in that each chapter may be regarded as the authors' personal account of their special insights and results that crystallised after several years of research into a given topic. The book revolves around several themes and offers a handful of scientific 'gems' of various colors, reflecting the great diversity of NMR. It contains 16 loosely connected chapters written by some of today's most accomplished NMR scientists in the world. Each chapter is a unique synthesis of the authors' previous research results in the given field, and thus projects special insights. Much emphasis has been given to the latest developments in NMR, in particular to selective pulses and pulsed field gradients. As a part of the series 'Analytical Spectroscopy Library', with subsequent editions coming along this book should provide a platform for future research accounts of similar flavor. The material is presented in a mostly non-mathematical fashion, and is intended mainly for chemists, application NMR scientists and students with already some background in NMR. Some of the chapters slightly overlap in the discussed topics, which is particularly exciting in terms of gaining insight into the same area from different angles.…

Buch. Condición: Neu. Neuware - During the 4th ESA-Congress, held in the Netherlands, 7-11 July 1996, a new perspective for agronomy emerged. Various contributions demonstrate the need for a new role of agronomy and its tools. In recent decades, agriculture has evolved from an activity with mainly productivity aims, into an issue conciliating environmental, agricultural, and economic and social objectives. Placing agriculture in such a broadened perspective requires a different agronomy, with new tools and approaches at a range of aggregration levels. It calls for detailed knowledge concerning the functioning, productivity and ecological relationships of agricultural plants and crops. In addition, it calls for a constant update and synthesis of existing and newly generated knowledge, the design of new ideotypes and genotypes, new production technologies, cropping systems, farming systems and agro-ecological land use systems.This proceedings book presents a set of case studies illustrating the various agronomic tools that can be used for specific agronomic questions. The case studies are grouped in sections illustrating relevant subquestions in developing an agriculture with broadened objectives. The book starts with an introductory paper on the role of agronomy in research and education in Europe. The second section deals with agricultural land use, food security and environment. This is followed by a set of papers describing experimental research and modeling approaches used to design new ideotypes of crops, including physiological properties in relation to growth factors such as radiation, CO2, temperature and water.Sustained soil fertility directly links to nutrient cycling and soil organic matter. A selected set of papers addresses the improvements in resource use efficiency and as such their contribution towards economic, environmental and agricultural objectives. The final section addresses the design of integrated and ecological arable farming systems. It highlights the role of prototyping interaction with leading-edge farmers, as promising tools to design, implement and test new farming systems.It is hoped that the activities of the European Society for Agronomy and the Proceedings of its 4th Congress will stimulate to serve the new perspectives of agronomy, i.e. to adopt ecological principles, to optimally manage the use of resources and to meet social and economic objectives.…

Buch. Condición: Neu. Neuware - Modern scientific and technological fields are frequently of an interdisciplinary nature, and the field of fibrous composites is no exception. Unlike fibre-reinforced plastics, the family of metal- and ceramic-based composites is still quite a new group of materials with a large variety of mechanical and physical properties. Up until now it has been difficult to produce these materials as the necessary technical information has not been well documented.The main purpose of this book is to link together fabrication, structure and properties chains, so as to clarify which structure provides the necessary properties, and how one can attain the correct composite structure. To this end, the book not only contains topics of a purely technical nature, but also a description of the failure mechanics of metal- and ceramic-matrix composites, as this is the key to understanding the structure-properties segment of the chain mentioned.The book is divided into three parts. Part I presents a general view of composites with the accent on metal- and ceramic-matrix composites. It also contains a brief description of modern fibres and composites and can be considered, at least for beginners, as a starting point for further study. Part II looks at the composite microstructures considered to be either optimal or reasonable in resisting a particular loading. Finally Part II describes a variety of mechanical, physical, and chemical potential for organizing these microstructures. Experimental data on technologies, material structures, and material properties are used throughout the book to support theoretical conclusions or to obtain important physical parameters.…
