Taschenbuch. Zustand: Neu. Neuware - Evolutionary Web Development examines the evolution of Web information systems, paying particular attention to the emergent attributes of electronic markets. It identifies four categories of architecture and demonstrates their virtues and limitations: static, interactive, adaptive, and agent-mediated systems.Advanced systems require the developer to truly understand the needs and preferences of customers. As well as such personal attributes, the availability of empirical data about the structure and content of Web information systems is a precondition for their effective assessment. Arno Scharl presents an automated and scalable approach to Web assessment. He emphasizes the role of feedback in an iterative cycle of design, implementation, usage, and analysis.

Taschenbuch. Zustand: Neu. Neuware - Biometric identity verification (BIV) offers a radical alternative to passports, PIN numbers, ID cards and driving licences. It uses physiological or behavioural characteristics such as fingerprints, hand geometry, and retinas to check a person's identity. It is therefore much less open to fraudulent use, which makes it ideal for use in voting systems, financial transactions, benefit payment administration, border control, and prison access.This is the first book to provide business readers with an easy-to-read, non-technical introduction to BIV systems. It explains the background and then tells the reader how to get their system up and running quickly. It will be an invaluable read for practitioners, managers and IT personnel - in fact for anyone considering, or involved in, implementing a BIV system.Julian Ashbourn was one of the pioneers in integrating biometric technology and has provided input into many prototype BIV systems around the world.

Buch. Zustand: Neu. Neuware - Diagnostic and interventional endoscopy has made rapid progress in recent years. Several methods are still under development and need to be properly evaluated. Bile duct diseases may have a negative impact on the liver, so early diagnosis and minimal invasive treatment options are important. Liver transplantation is now established for the treatment of liver failure. Hepatic surgery may lead to problems in the bile ducts which can be treated by endoscopic intervention. A broad spectrum of indications for interventional endoscopy in hepatology exists. This book, the proceedings of Falk Symposium No. 116, held in Basel, Switzerland, October 25 1999 (Part III of the Basel Liver Week 1999), describes the state of the art and new developments in endoscopy for these treatments, and contains chapters by well-known experts from all over the world.

Buch. Zustand: Neu. Neuware - Goal Directed Proof Theory presents a uniform and coherent methodology for automated deduction in non-classical logics, the relevance of which to computer science is now widely acknowledged. The methodology is based on goal-directed provability. It is a generalization of the logic programming style of deduction, and it is particularly favourable for proof search. The methodology is applied for the first time in a uniform way to a wide range of non-classical systems, covering intuitionistic, intermediate, modal and substructural logics. The book can also be used as an introduction to these logical systems form a procedural perspective. Readership: Computer scientists, mathematicians and philosophers, and anyone interested in the automation of reasoning based on non-classical logics. The book is suitable for self study, its only prerequisite being some elementary knowledge of logic and proof theory.

Taschenbuch. Zustand: Neu. Neuware - The past few decades have witnessed an increasing interest in the field of multidimensional systems theory. This is concerned with systems whose trajectories depend not on one single variable (usually interpreted as time or frequency), but on several independent variables, such as the coordinates of an image.The behavioural approach introduced by J. C. Willems provides a particularly suitable framework for developing a linear systems theory in several variables. The book deals with the classical concepts of autonomy, controllability, observability, and stabilizability. All the tests and criteria given are constructive in the sense that algorithmic versions may be implemented in modern computer algebra systems, using Gröbner basis techniques.There is a close connection between multidimensional systems theory and robust control of one-dimensional systems with several uncertain parameters. The central link consists in the basic tool of linear fractional transformations. The book concludes with examples from the theory of electrical networks.

Buch. Zustand: Neu. Neuware - Object relationships in modern software systems are becoming increasingly numerous and complex, and program errors due to violations of object relationships are difficult to detect. Programmers need new tools that allow them to explore objects in a large system more efficiently and to detect broken object relationships instantaneously. Such tools incorporate approaches used in such areas as data visualization, pattern matching and extraction, database querying, active databases, and rule-based programming. The query-based debugging approach developed by the author of this book is another powerful yet efficient tool to be added to the developer's tool chest. Advanced Debugging Methods presents practice and tools for debugging computer programs. This book proposes new powerful approaches that simplify the daunting task of debugging complex software systems. Although debugging has been addressed in numerous research papers, many of its methods have yet to be explored in a book-length format. This book helps to fill this gap by presenting an overview of existing debugging tools with motivating examples and case studies, as well as presenting new, state-of-the-art debugging methods. Advanced Debugging Methods will be of use to software developers looking for tools to be applied in cutting edge practice; system architects looking at the relationship between software design and debugging; tools and programming language researchers looking for new ideas in run-time tool implementation as well as detailed descriptions of advanced implementations; and university professors and graduate students who will use this book as supplementary reading for graduate courses in programming tools, language implementation, and advanced object-oriented systems. Advanced Debugging Methods is also a handy reference of currently existing debugging methodologies as well as a springboard for cutting-edge research to simplify thedifficult task of debugging and to facilitate the development of more robust software systems.

Buch. Zustand: Neu. Neuware - It is an obvious fact that human agency is constrained and structured by many kinds of rules: rules that are constitutive for communication, morality, persons, and society, and juridical rules. So the question is: what roles are played by social rules and the structural traits of human agency in rational decision making What bearing does this have on the theory of practical rationality These issues can only be discussed within an interdisciplinary setting, with researchers drawn from philosophy, decision theory and the economic and social sciences. The problem is of profound, fundamental concern to the social scientist and has attracted a great deal of intellectual effort. Contributors include distinguished researchers in their respective fields and the book thus presents state-of-the-art theory. It can also be used as a textbook in advanced philosophy, economics and social science classes.

Buch. Zustand: Neu. Neuware - Elie Metchnikoff (1845-1916), winner of the Nobel Prize in 1907 for his contributions to immunology, was first a comparative zoologist, who, working in the wake of Darwin's On the Origin of Species, made seminal contributions to evolutionary biology. His work in comparative embryology is best known in regard to the debates with Ernst Haeckel concerning animal genealogical relationships and the theoretical origins of metazoans. But independent of those polemics, Metchnikoff developed his `phagocytosis theory' of immunity as a result of his early comparative embryology research, and only in examining the full breadth of his work do we appreciate his signal originality. Metchnikoff's scientific papers have remained largely untranslated into English. Assembled here, annotated and edited, are the key evolutionary biology papers dating from Metchnikoff's earliest writings (1865) to the texts of his mature period of the 1890s, which will serve as an invaluable resource for those interested in the historical development of evolutionary biology.

Buch. Zustand: Neu. Neuware - This edited volume addresses a subject which has been discussed inten sively in the computer vision community for several years. Performance characterization and evaluation of computer vision algorithms are of key importance, particularly with respect to the configuration of reliable and ro bust computer vision systems as well as the dissemination of reconfigurable systems in novel application domains. Although a plethora of literature on this subject is available for certain' areas of computer vision, the re search community still faces a lack of a well-grounded, generally accepted, and--eventually-standardized methods. The range of fundamental problems encoIl!passes the value of synthetic images in experimental computer vision, the selection of a representative set of real images related to specific domains and tasks, the definition of ground truth given different tasks and applications, the design of experimental test beds, the analysis of algorithms with respect to general characteristics such as complexity, resource consumption, convergence, stability, or range of admissible input data, the definition and analysis of performance measures for classes of algorithms, the role of statistics-based performance measures, the generation of data sheets with performance measures of algorithms sup porting the system engineer in his configuration problem, and the validity of model assumptions for specific applications of computer vision.

Buch. Zustand: Neu. Neuware - religious values at the office door. Apartheid was an evil, and business had great power in South Africa. Where there is power, there is also responsibil ity. I prayed about this long and hard. I pushed the companies as much as I thought I could. There were advances and there were setbacks, but finally we prevailed and the Blacks of South Africa secured their freedom. My effort in behalf of the Sullivan Principles was only one of a number of significant efforts of the anti-apartheid movement. All of those other efforts must be recognized, as well. The Sullivan Principles and the manner in which they were implemented in South Africa were in the nature of a grand experiment in the sociopolitical change and economic uplifting of the Black people of South Africa. What is even more important is that the Principles were driven by an ethical and moral imperative, and were voluntarily implemented by a group of enlight ened United States multinational corporations. No grand design or vision is ever perfect. We fall prey to human follies, limited understanding of the future, and necessary compromises to seek not what is perfect but what is possible. Thus, any such effort is subject to criticism from those who seek ideological purity and those who seek to minimize the impact of change from the status quo . .

Buch. Zustand: Neu. Neuware - The end of the Cold War marked the beginning of a new era of facing the legacy of the arms race. The enormous challenge confronting us now is to strengthen the fragile nature of the new political balance. The beginning of this new historical period is characterized by mistrust, and the best way to ease these tensions is through international collaborations. Moreover, the intimate nature of close, non-invasive, collaborative work on environmental problems can help establish a secure foundation of mutual understanding and trust. Environmental projects are non-threatening to national security issues and may involve collaborations throughout the international weapons complex. Personal and individual scientific relationships quite often spearhead agreements at the government-to-government level. Environmental and nonproliferation issues are of great importance to the citizens of Russia, to the states of the Former Soviet Union, and to neighboring countries. The activities associated with decontamination and decommissioning of old facilities, environmental restoration, security enhancements, monitoring and surveillance, and risk reduction should provide a significant employment potential for scientists and engineers of the weapons complex of the Former Soviet Union.

Buch. Zustand: Neu. Neuware - Expert testimony relying on scientific and other specialized evidence has come under increased scrutiny by the legal system. A trilogy of recent U.S. Supreme Court cases has assigned judges the task of assessing the relevance and reliability of proposed expert testimony. In conjunction with the Federal judiciary, the American Association for the Advancement of Science has initiated a project to provide judges indicating a need with their own expert. This concern with the proper interpretation of scientific evidence, especially that of a probabilistic nature, has also occurred in England, Australia and in several European countries. Statistical Science in the Courtroom is a collection of articles written by statisticians and legal scholars who have been concerned with problems arising in the use of statistical evidence. A number of articles describe DNA evidence and the difficulties of properly calculating the probability that a random individ ual's profile would 'match' that of the evidence as well as the proper way to intrepret the result. In addition to the technical issues, several authors tell about their experiences in court. A few have become disenchanted with their involvement and describe the events that led them to devote less time to this application. Other articles describe the role of statistical evidence in cases concerning discrimination against minorities, product liability, environmental regulation, the appropriateness and fairness of sentences and how being involved in legal statistics has raised interesting statistical problems requiring further research.

Buch. Zustand: Neu. Neuware - In 1992, the Falk Symposium No. 70 dealt with the topic `Immunology and Liver'. At that time basic mechanisms of immunology as well as immunopathogenetic mechanisms in viral and autoimmune liver diseases were discussed. Now, 7 years later, the Falk Symposium No. 114, held in Basel, Switzerland, October 20-21 1999 (Part I of the Basel Liver Week 1999), focused on immunology in autoimmune liver diseases. In the first section basic mechanisms of autoimmunity are presented, including the relevance of superantigens and the role of apoptosis. A further topic is the latest developments concerning animal models for autoimmune diseases. Recently the International Autoimmune Hepatitis Group newly defined and reclassified the syndrome of autoimmune hepatitis. Autoimmune hepatitis is now identified and studied in all parts of the world, including Asia and South America. A special variant of autoimmune hepatitis was identified as one organ manifestation of the autoimmune polyendocrine syndrome type 1, a genetic disease caused by mutations in a single transcription factor. Drug- and hepatitis-virus induced immune mediated liver diseases may serve as models for nonhepatic immune mediated disorders. DNA technology has increased our knowledge of the immunogenetic background of autoimmune liver diseases. Among the cholestatic immune mediated liver diseases, significant progress has been made concerning primary biliary cirrhosis, in particular regarding the identification of mitochondrial antigens and the characterisation of the immune reactions directed at them. The involvement of infectious agents in PBC as well as the definition of overlap syndromes is a particular focus for basic and clinical research in this area. Concerning the therapy of autoimmune liver diseases, corticosteroids and azathioprin remain the state of the art for autoimmune hepatitis, while bile acids have become well established in treatment of primary biliary cirrhosis as wellas primary sclerosing cholangitis. New drugs in the future will include topical steroids such as budesonide and new immunosuppressive agents like mofetil/mycophenolate. Liver transplantation is the treatment of choice for end stage liver diseases; all autoimmune liver diseases are among the best candidates for liver transplantation. Hopefully, new therapeutic strategies based on the results obtained from experimental models will become everyday clinical practice in the next decade. Therefore this symposium concludes with a discussion.

Buch. Zustand: Neu. Neuware - Knowledge discovery is an area of computer science that attempts to uncover interesting and useful patterns in data that permit a computer to perform a task autonomously or assist a human in performing a task more efficiently. Soft Computing for Knowledge Discovery provides a self-contained and systematic exposition of the key theory and algorithms that form the core of knowledge discovery from a soft computing perspective. It focuses on knowledge representation, machine learning, and the key methodologies that make up the fabric of soft computing - fuzzy set theory, fuzzy logic, evolutionary computing, and various theories of probability (e.g. naïve Bayes and Bayesian networks, Dempster-Shafer theory, mass assignment theory, and others). In addition to describing many state-of-the-art soft computing approaches to knowledge discovery, the author introduces Cartesian granule features and their corresponding learning algorithms as an intuitive approach to knowledge discovery. This new approach embraces the synergistic spirit of soft computing and exploits uncertainty in order to achieve tractability, transparency and generalization. Parallels are drawn between this approach and other well known approaches (such as naive Bayes and decision trees) leading to equivalences under certain conditions. The approaches presented are further illustrated in a battery of both artificial and real-world problems. Knowledge discovery in real-world problems, such as object recognition in outdoor scenes, medical diagnosis and control, is described in detail. These case studies provide further examples of how to apply the presented concepts and algorithms to practical problems. The author provides web page access to an online bibliography, datasets, source codes for several algorithms described in the book, and other information. Soft Computing for Knowledge Discovery is for advanced undergraduates,professionals and researchers in computer science, engineering and business information systems who work or have an interest in the dynamic fields of knowledge discovery and soft computing.

Buch. Zustand: Neu. Neuware - In 1998 Armenia was commemorating the tenth anniversary of the catastrophic Spitak earthquake. The Second International Conference on 'Earthquake Hazard and Seismic Risk Reduction' sponsored by the Government of the Republic of Armenia and United Nation's International Decade for Natural Disaster Reduction (UN/IDNDR) was held in dedication to that event between 14-21 September (later referred to as Yerevan Conference). The Yerevan Conference has been organized by the National Survey for Seismic Protection (NSSP) of the Republic of Armenia. All level's decision-makers (from the ministers to the local authorities), politicians, scientists, leaders of the executive and legislative powers, psychologists, leading businessmen, representatives from the private sector and the media as well as from the International Organizations have been invited by the Armenian NSSP to take part in joint discussion of the Seismic Risk Reduction Problem for the first time in the history of such forums. Armenian NSSP's such initiative has been triggered by the experience of the Spitak earthquake and other disasters. They showed that it will be possible to reduce the risks, posed by the natural disaster, only through the common efforts of all the community in co-operation with the International institutions.

Buch. Zustand: Neu. Neuware - The education of humanity is the key to the next century's culture, its social and practical life. The main concerns of education are perennial, but the continuous flood of inventions, the technological innovations that re-shape life, calls for a radically new appraisal of the situation, such as only philosophy can provide. Answering the call of humanity for the measure, sense of proportion and direction that could re-orient present and future education, the phenomenology of life - integral and scientific, in a dialogue with the arts, the sciences, and the humanities - proposes an ontopoietic model of life's unfolding as the universal paradigm for this re-orientation. Taking the Human Creative Condition as its Archimedean point, it offers a unique context for a fresh investigation of the concerns of education, both perennial and immediate.

Buch. Zustand: Neu. Neuware - Dictation systems, read-aloud software for the blind, speech control of machinery, geographical information systems with speech input and output, and educational software with `talking head' artificial tutorial agents are already on the market. The field is expanding rapidly, and new methods and applications emerge almost daily. But good sources of systematic information have not kept pace with the body of information needed for development and evaluation of these systems. Much of this information is widely scattered through speech and acoustic engineering, linguistics, phonetics, and experimental psychology. The Handbook of Multimodal and Spoken Dialogue Systems presents current and developing best practice in resource creation for speech input/output software and hardware. This volume brings experts in these fields together to give detailed `how to' information and recommendations on planning spoken dialogue systems, designing and evaluating audiovisual and multimodal systems, and evaluating consumer off-the-shelf products. In addition to standard terminology in the field, the following topics are covered in depth: How to collect high quality data for designing, training, and evaluating multimodal and speech dialogue systems; How to evaluate real-life computer systems with speech input and output; How to describe and model human-computer dialogue precisely and in depth. Also included: The first systematic medium-scale compendium of terminology with definitions.This handbook has been especially designed for the needs of development engineers, decision-makers, researchers, and advanced level students in the fields of speech technology, multimodal interfaces, multimedia, computational linguistics, and phonetics.

Buch. Zustand: Neu. Neuware - Quantum Theory, together with the principles of special and general relativity, constitute a scientific revolution that has profoundly influenced the way in which we think about the universe and the fundamental forces that govern it. The Historical Development of Quantum Theory is a definitive historical study of that scientific work and the human struggles that accompanied it from the beginning. Drawing upon such materials as the resources of the Archives for the History of Quantum Physics, the Niels Bohr Archives, and the archives and scientific correspondence of the principal quantum physicists, as well as Jagdish Mehra's personal discussions over many years with most of the architects of quantum theory, the authors have written a rigorous scientific history of quantum theory in a deeply human context. This multivolume work presents a rich account of an intellectual triumph: a unique analysis of the creative scientific process. The Historical Development of Quantum Theory is science, history, and biography, all wrapped in the story of a great human enterprise. Its lessons will be an aid to those working in the sciences and humanities alike.

Buch. Zustand: Neu. Neuware - Most routine motor tasks are complex, involving load transmission through out the body, intricate balance, and eye-head-shoulder-hand-torso-leg coor dination. The quest toward understanding how we perform such tasks with skill and grace, often in the presence of unpredictable perturbations, has a long history. This book arose from the Ninth Engineering Foundation Con ference on Biomechanics and Neural Control of Movement, held in Deer Creek, Ohio, in June 1996. This unique conference, which has met every 2 to 4 years since the late 1960s, is well known for its informal format that promotes high-level, up-to-date discussions on the key issues in the field. The intent is to capture the high quality ofthe knowledge and discourse that is an integral part of this conference series. The book is organized into ten sections. Section I provides a brief intro duction to the terminology and conceptual foundations of the field of move ment science; it is intended primarily for students. All but two of the re maining nine sections share a common format: (l) a designated section editor; (2) an introductory didactic chapter, solicited from recognized lead ers; and (3) three to six state-of-the-art perspective chapters. Some per spective chapters are followed by commentaries by selected experts that provide balance and insight. Section VI is the largest section, and it con sists of nine perspective chapters without commentaries.

For labor and lactation oxytocin you must buy! Enkephalin always gives a good runner's high! So won't you try peptides Small proteins, the best in the land!' The above words [1], penned by Gary Gisselman to open Peptide Ångst: La Triviata, the opera which made its world premiere on July 1, 1999, also serve as a fitting charge to the th 16 American Peptide Symposium. This latest edition of a premier biennial series was held under the auspices of the American Peptide Society, June 26-July 1, 1999, at the Minneapolis Convention Center, Minneapolis,Minnesota, with the undersigned serving as Co-Chairs. The fortunate coincidence of the calendar allowed us to set as the theme 'Peptides for the New Millennium', and in our judgment, the approximately 1200 participants [2] who converged in the Twin Cities from academic and industrial institutions in 36 countries were treated to an exciting and stimulating conference that left most everyone with an enthusiastic vision for the future of our field. The present Proceedings volume should serve as a handy reference source and succinct snapshot of peptide science at essentially its century mark - the clock having started with the initial contributions of Emil Fischer and Th. Curtius.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -An increasing number of people are taking advantage of the relatively low prices of astronomical equipment. Many of these people are doing so with little knowledge of practical astronomy and, as the volume of questions asked at astronomical society meetings and on internet newsgroups attest, there is a need for these questions to be answered in one place. Hence this book. The fundamental premise behind AstroFAQs is that the beginning amateur astronomer wishes to get 'up and running' with the minimum delay. A secondary premise is that anyone will better appreciate why something is done as it is if there is an understanding of the underlying principles. AstroFAQs addresses both these premises. AstroFAQs makes no pretence to go into great depth -that would be impossible in such a slim volume -but it will give you the kick-start you need to choose and use your instrument effectively, and will take you to a level of expertise that is significantly higher than the 'beginner' status. It uses a hierarchical section num bering system that simplifies cross-referencing. Suggestions for more in-depth reading are given throughout. More and more 'newbie' astronomers are entering this fascinating hobby by purchasing one of the 'gee whiz' GOTO telescopes, of which there is an increasing selection. These serve the wish to begin observation as soon as possible, but they do so at a price premium. 124 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Questions that arose from linear programming and combinatorial optimization have been a driving force for modern polytope theory, such as the diameter questions motivated by the desire to understand the complexity of the simplex algorithm, or the need to study facets for use in cutting plane procedures. In addition, algorithms now provide the means to computationally study polytopes, to compute their parameters such as flag vectors, graphs and volumes, and to construct examples of large complexity. The papers of this volume thus display a wide panorama of connections of polytope theory with other fields. Areas such as discrete and computational geometry, linear and combinatorial optimization, and scientific computing have contributed a combination of questions, ideas, results, algorithms and, finally, computer programs. 225 pp. Englisch.
