And in software engineering, there has been no technology more disruptive than outsourcing. That it should so quickly reach maturity and an unparalleled scale is truly remarkable; that it should now be called to demonstrate its sustainability in the current nancial turmoil is the challenge that will prove whether and how it will endure. Early signs under even the bleak market conditions of the last 12 months are that it will not only survive, it will rmly establish its role across the world of business. Outsourcing throws into sharp focus the entire software engineering life- cle. Topics as diverse as requirements analysis, concurrency and model-checking need to nd a composite working partnership in software engineering practice. This con uence arises from need, not dogma, and the solutions required are those that will have the right e ect on the associated activities in the world of the application: e.g., reducing the time for a transaction or making the results of a complex analysis available in real-time. While the business of outsourcing continues to be studied, the engineering innovations that make it compelling are constantly changing. It is in this milieu that this series of conferences has placed itself. 224 pp. Englisch.

Buch. Condición: Neu. Neuware -Dynamics is what characterizes virtually all phenomenae we face in the real world, and processes that proceed in practically all kinds of inanimate and animate systems, notably social systems. For our purposes dynamics is viewed as time evolution of some characteristic features of the phenomenae or processes under consideration. It is obvious that in virtually all non-trivial problems dynamics can not be neglected, and should be taken into account in the analyses to, first, get insight into the problem consider, and second, to be able to obtain meaningful results.A convenient tool to deal with dynamics and its related evolution over time is to use the concept of a dynamic system which, for the purposes of this volume can be characterized by the input (control), state and output spaces, and a state transition equation. Then, starting from an initial state, we can find a sequence of consecutive states (outputs) under consecutive inputs (controls). That is, we obtain a trajectory. The state transition equation may be given in various forms, exemplified by differential and difference equations, linear or nonlinear, deterministic or stochastic, or even fuzzy (imprecisely specified), fully or partially known, etc. These features can give rise to various problems the analysts may encounter like numerical difficulties, instability, strange forms of behavior (e.g. chaotic), etc.This volume is concerned with some modern tools and techniques which can be useful for the modeling of dynamics. We focus our attention on two important areas which play a key role nowadays, namely automation and robotics, and biological systems. We also add some new applications which can greatly benefit from the availability of effective and efficient tools for modeling dynamics, exemplified by some applications in security systems. 192 pp. Englisch.

Buch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - Nelson Goodman's disparate writings are often written about only within their own particular discipline, such that the epistemology is discussed in contrast to others' epistemology, the aesthetics is contrasted with more traditional aesthetics, and the ontology and logic is viewed in contrast to both other contemporary philosophers and to Goodman's historical predecessors. This book argues that that is not an adequate way to view Goodman. The separate disciplines of ontology, epistemology, and aesthetics should be viewed as sequential steps within his thought, such that each provides the ground rules for the next section and, furthermore, providing the reasons for limitations on the terms available to the subsequent writing(s). This is true not merely because this is the general chronology of his writing, but more importantly because within his metaphysics lies Goodman's basic nominalist ontology and logic, and it is upon those principles that he builds his epistemology and, furthermore, it is the sum of both the metaphysics and the epistemology, with the nominalist principle as the guiding force, which constructs the aesthetics. At the end of each section of this book, the consequent limitations imposed on his terms and concepts available to him are explicated, such that, by the end of the book, the book delineates the constraints imposed upon the aesthetics by both the metaphysics and the epistemology.This book will benefit not only the professionals in the field of philosophy, but will also help both graduate and upper level undergraduate students understand Goodman's disparate writings within their proper context, and hopefully will also encourage them to view philosophical thinking in a less truncated and departmentalized way.

Buch. Condición: Neu. Neuware - Light-based therapies have been a major component of dermatologic practice. Historically, these treatment modalities have been mainly tailored to the treatment of patients with light skin. Principles governing use of light therapies in skin of color are less defined. However, there is a tremendous need to understand the benefits and limitations of these therapeutic options for dark-skinned patients as well. Demographic data in the United States alone indicate that the population and recipients of health care are rapidly changing with regard to skin phototype. Physicians who are involved in the delivery of care for patients with cutaneous problems that can be addressed by light treatments need to be able to fully understand the mechanisms, applications, risks, efficacy, adverse events, and other pertinent issues in considering treatment options for their patients with pigmented skin.

Buch. Condición: Neu. Neuware - The sober explanation for this book is a call by the Springer-Verlag, London, to edit a publication on 'The functional relevance of the collateral circulation' of the heart. Alternatively, it could be 'sold' as the result of my intention to reduce entropy of 18 years of scientific work on the topic of the coronary circulation, which was itself meant to diminish the amount of 'useless' energy. Such a process of reducing disarray in a system with the aim of grasping it better is related to simplification, which carries the risk of introducing error. This can be exemplified by the historic view of angina pectoris, which used to be simplified as being always fatal, thus obscuring for nearly two centuries the view of a 'self-healing' mechanism such as the collateral circulation of the heart. It would be na ve, to assume the present work to be free of erroneous oversimplification, because the very nature of scientific work is related to generating (simple) hypotheses with their subsequent falsification. In that context and bluntly, my primary interest in the field of the collateral circulation was not initiated with a vision of eradicating the consequences of coronary artery disease (CAD) by promoting the growth of natural bypasses. The time for such sizeable ideas had passed in the 1970s with the start of the work by Wolfgang Schaper.

Buch. Condición: Neu. Neuware - Random variables are rarely independent in practice and so many multivariate distributions have been proposed in the literature to give a dependence structure for two or more variables. In this book, we restrict ourselves to the bivariate distributions for two reasons: (i) correlation structure and other properties are easier to understand and the joint density plot can be displayed more easily, and (ii) a bivariate distribution can normally be extended to a multivariate one through a vector or matrix representation. This volume is a revision of Chapters 1-17 of the previous book Continuous Bivariate Distributions, Emphasising Applications authored by Drs. Paul Hutchinson and Chin-Diew Lai.The book updates the subject of copulas which have grown immensely during the past two decades. Similarly, conditionally specified distributions and skewed distributions have become important topics of discussion in this area of research. Thisvolume, which provides an up-to-date review of various developments relating to bivariate distributions in general, should be of interest to academics and graduate students, as well as applied researchers in finance, economics, science, engineering and technology.N. BALAKRISHNAN is Professor in the Department of Mathematics and Statistics at McMaster University, Hamilton, Ontario, Canada. He has published numerous research articles in many areas of probability and statistics and has authored a number of books including the four-volume series on Distributions in Statistics, jointly with Norman L. Johnson and S. Kotz, published by Wiley. He is a Fellow of the American Statistical Association and the Institute of Mathematical Statistics, and the Editor-in-Chief of Communications in Statistics and the Executive Editor of Journal of Statistical Planning and Inference.CHIN-DIEW LAI holds a Personal Chair in Statistics at Massey University, Palmerston North, New Zealand. He has published more than 100 peer-reviewed research articles and co-authored three well-received books. He was a former editor-in-chief and is now an Associate Editor of the Journal of Applied Mathematics and Decision Sciences.

Buch. Condición: Neu. Neuware - The texts of Boris Hessen and Henryk Grossmann assembled in this volume are important contributions to the historiography of the Scienti c Revolution and to the methodology of the historiography of science. They are of course also historical documents, not only testifying to Marxist discourse of the time but also illustrating typical European fates in the rst half of the twentieth century. Hessen was born a Jewish subject of the Russian Czar in the Ukraine, participated in the October Revolution and was executed in the Soviet Union at the beginning of the purges. Grossmann was born a Jewish subject of the Austro-Hungarian Kaiser in Poland and served as an Austrian of cer in the First World War; afterwards he was forced to return to Poland and then because of his revolutionary political activities to emigrate to Germany; with the rise to power of the Nazis he had to ee to France and then Americawhilehisfamily,whichremainedinEurope,perishedinNaziconcentration camps. Our own acquaintance with the work of these two authors is also indebted to historical context (under incomparably more fortunate circumstances): the revival of Marxist scholarship in Europe in the wake of the student movement and the p- fessionalization of history of science on the Continent. We hope that under the again very different conditions of the early twenty- rst century these texts will contribute to the further development of a philosophically informed socio-historical approach to the study of science.

Buch. Condición: Neu. Neuware - This research program began in 1993. The idea of developing representative samples of those active in the business creation process, now called nascent entrepreneurs, developed from the success of using regional characteristics to 1 predict variations in new firm birth rates in six countries. The initial purpose was to determine those external factors that encouraged individuals to initiate the business creation process and become, as they are now called, nascent entrepreneurs. The research procedures, mainly the critical aspects of the scre- ing procedures, were developed with the Survey Research Laboratory at the University of Wisconsin in Madison to complete the Wisconsin Entrepreneurial 2 Climate Study. Support for an initial test with a national sample was provided by the Institute for Social Research at the University of Michigan. Richard Curtin became involved with the incorporation of the screening module as part 3 of the Survey of Consumers in October and November in 1993. The success of these efforts in providing a detailed description of the ent- preneurial process based on representative samples led to substantial interest among entrepreneurial scholars. A founding team of Nancy Carter, William Gartner, and Paul Reynolds was able to organize the Entrepreneurial Research Consortium (ERC), a collaborative network of 34 research units that shared the financial cost and sweat equity required to implement the first national project, 4 PSED I.

It is also suitable as a reference or secondary text for advanced-level students in computer science and computer or electrical engineering.

Buch. Condición: Neu. Neuware - The psychoanalytic approach to religion has changed radically during the course of the twentieth century. In both clinical and theoretical work in psychoanalysis, developments have taken place that frequently are not noted by persons who assume that all that can be said has been said by Freud.The study of religious phenomena, persons, events and traditions has always been a substantial part of applied psychoanalysis and here also major developments have taken place. It is no exaggeration to state that the scientific study of religion has been revolutionized by the integration of psychological perspectives, including the field of psychoanalysis.This volume differs from other recent publications on the topic of psychoanalysis and religion in drawing upon the entire field of psychoanalytic involvement with religion. It is interdisciplinary in approach and unlike other books on the topic brings together an exceptional combination of theoretical, empirical and clinical studies. No other book provides integrated examples of all three types of work.

Buch. Condición: Neu. Neuware - In today's world, three great classes of non-infectious diseases - the metabolic syndromes (such as type 2 diabetes and atherosclerosis), the cancers, and the neurodegenerative disorders - have risen to the fore. These diseases, all associated with increasing age of an individual, have proven to be remarkably complex and difficult to treat. This is because, in large measure, when the cellular signaling pathways responsible for maintaining homeostasis and health of the body become dysregulated, they generate equally stable disease states. As a result the body may respond positively to a drug, but only for a while and then revert back to the disease state. Cellular Signaling in Health and Disease summarizes our current understanding of these regulatory networks in the healthy and diseased states, showing which molecular components might be prime targets for drug interventions. This is accomplished by presenting models that explain in mechanistic, molecular detail how a particular part of the cellular signaling web operates properly in health and improperly in disease.The stability of the health- and disease-associated states is dynamic and supported by multiple feedback loops acting positively and negatively along with linkages between pathways. During the past few years an ongoing series of important discoveries have been made that advance our understanding of how the body works and may guide us on how to better deal with these diseases. These include the discovery of chronic inflammation as a causal factor in all of these disease classes, the appearance of reactive oxygen species as a messenger molecule that can act both positively and negatively, the propensity of proteins to misfold into aggregation- and disease-prone forms, and the rise of epigenetics including the emergence of small non-coding RNA with important regulatory functions out of the so-called junk RNA. Chapters are devoted to each of these classes of findings with additional detailsintegrated into the chapters dealing directly with the diseases. The connections responsible for maintaining stability are explored in depth.

Buch. Condición: Neu. Neuware - Multi-Agent Systems are a promising technology to develop the next generation open distributed complex software systems. The main focus of the research community has been on the development of concepts (concerning both mental and social attitudes), architectures, techniques, and general approaches to the analysis and specification of multi-agent systems. This contribution has been fragmented, without any clear way of 'putting it all together', rendering it inaccessible to students and young researchers, non-experts, and practitioners. Successful multi-agent systems development is guaranteed only if we can bridge the gap from analysis and design to effective implementation.Multi-Agent Programming: Languages, Tools and Applications presents a number of mature and influential multi-agent programming languages, platforms, development tools and methodologies, and realistic applications, summarizing the state of the art in an accessible manner for professionals and computer science students at all levels.

Neuware - Object Oriented Simulation will qualify as a valuable resource to students and accomplished professionals and researchers alike, as it provides an extensive, yet comprehensible introduction to the basic principles of object-oriented modeling, design and implementation of simulation models.Key features include an introduction to modern commercial graphical simulation and animation software, accessible breakdown of OOSimL language constructs through various programming principles, and extensive tutorial materials ideal for undergraduate classroom use.

Buch. Condición: Neu. Neuware - Artificial organs have come a long way since the first dialysis machine, the rotating artificial kidney, was invented in 1944 by Willem Johan Kolff, who is known as the ''father of artificial organs''. At that time he met stiff resistance from his hospital superiors but his persistence paid off and a million saved lives have been attributed to his first invention. He was indeed the first to mix medicine and engineering. An artificial organ is any machine, device, or other material that is used to replace the functions of a faulty or missing organ or other parts of the human body. Some body parts are more of a challenge than others. The heart has one purpose and it is to pump blood; however, the liver has biochemical and physiological functions which are difficult to simulate. The implantation of an artificial organ is critical because of the patient life dependency on the artificial organ itself. The treatment of choice is organ transplantation, however, transplant candidates face a long waiting time and many die while on the waiting list. In addition there are patients who are excluded from transplantation because of age or presence of other diseases. This book p- sents an overview of the current state of knowledge of artificial organs including the liver, pancreas, kidney, heart, cochlea, skin, stem cells, composite tissue allograft, and sphincters.

Buch. Condición: Neu. Neuware - In Memoriam of Alfred S. Evans The third edition of Bacterial Infections of Humans is dedicated to Alfred Spring Evans, who died on January 21, 1996, 2 ½ years after a diagnosis of cancer. Al was the senior editor of this textbook, which he founded with Harry Feldman in 1982. Al was a clinician, epidemiologist, educator, ca- lyst for biomedical research, historian, author, speaker, seeker of the truth, sincere friend of students, sports enthusiast, traveler, and truly a man of all seasons. He was a devoted husband to Brigette Klug Evans, father of three children, and grandfather of four. Al was born in Buffalo, New York, on August 21, 1917, to Ellen Spring and John H. Evans, M. D. , one of the United States's rst anesthesiologists and an early researcher in the eld of oxygen therapy. He received his undergraduate training at the University of Michigan; was awarded an M. D. degree in 1943 from the University of Buffalo; interned in Pittsburgh, Pe- sylvania; and performed his medical residency at the Goldwater Hospital in New York City. He was in the United States Army from 1944 to 1946, assigned as a public health of cer to a base in Okinawa, Japan. It was there that he met Drs. Albert Sabin and John R. Paul, who came to Okinawa to test a new Japanese encepha- tis vaccine. Al was invited by Dr. Paul to come to Yale Alfred S.

Buch. Condición: Neu. Neuware - It is a great honor to be asked to introduce this exciting new volume, having been heavily involved in the first comprehensive synthesis in the early 1980s. Gibbons are the most enthralling of primates. On the one hand, they are the most appealing animals, with their upright posture and body shape, facial markings, dramatic arm-swinging locomotion and suspensory postures, and devastating duets; on the other hand, the small apes are the most diverse, hence biologically valuable and informative, of our closest relatives. It is hard for me to believe that it is 40 years to the month since I first set foot on the Malay Peninsula to start my doctoral study of the siamang. I am very proud to have followed in the footsteps of the great pioneer of primate field study, Clarence Ray Carpenter (CR or Ray, who I was fortunate to meet twice, in Pennsylvania and in Zurich), first in Central America (in 1967) and then in Southeast Asia. It is 75 years since he studied howler monkeys on Barro Colorado Island in the Panama Canal Zone. It is 70 years since he studied the white-handed gibbon in Thailand.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -We live in an information age that requires us, more than ever, to represent, access, and use information. Over the last several decades, we have developed a modern science and technology for information retrieval, relentlessly pursuing the vision of a 'memex' that Vannevar Bush proposed in his seminal article, 'As We May Think.' Faceted search plays a key role in this program. Faceted search addresses weaknesses of conventional search approaches and has emerged as a foundation for interactive information retrieval. User studies demonstrate that faceted search provides more effective information-seeking support to users than best-first search. Indeed, faceted search has become increasingly prevalent in online information access systems, particularly for e-commerce and site search. In this lecture, we explore the history, theory, and practice of faceted search. Although we cannot hope to be exhaustive, our aim is to provide sufficient depth and breadth to offer a useful resource to both researchers and practitioners. Because faceted search is an area of interest to computer scientists, information scientists, interface designers, and usability researchers, we do not assume that the reader is a specialist in any of these fields. Rather, we offer a self-contained treatment of the topic, with an extensive bibliography for those who would like to pursue particular aspects in more depth. Table of Contents: I.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The integration of ubiquitous mobile computing resources into physical spaces can potentially affect the development, maintenance, and transformation of communities and social interactions and relations within a particular context or location. Ubiquitous mobile computing allows users to engage in activities in diverse physical locations, to access resources specific to the location, and to communicate directly or indirectly with others. Mobile technologies can potentially enhance social interactions and users' experiences, extend both social and informational resources available in context, and greatly alter the nature and quality of our interactions. Activities using mobile devices in context generate complex systems of interactions, and the benefits of ubiquity and mobility can be easily lost if that complexity is not appreciated and understood. This monograph attempts to address issues of using and designing location-based computing systems and the use of these tools to enhance social awareness, navigate in spaces, extend interactions, and influence others.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Documents usually have a content and a structure. The content refers to the text of the document, whereas the structure refers to how a document is logically organized. An increasingly common way to encode the structure is through the use of a mark-up language. Nowadays, the most widely used mark-up language for representing structure is the eXtensible Mark-up Language (XML). XML can be used to provide a focused access to documents, i.e. returning XML elements, such as sections and paragraphs, instead of whole documents in response to a query. Such focused strategies are of particular benefit for information repositories containing long documents, or documents covering a wide variety of topics, where users are directed to the most relevant content within a document. The increased adoption of XML to represent a document structure requires the development of tools to effectively access documents marked-up in XML. This book provides a detailed description of query languages, indexing strategies, ranking algorithms, presentation scenarios developed to access XML documents. Major advances in XML retrieval were seen from 2002 as a result of INEX, the Initiative for Evaluation of XML Retrieval. INEX, also described in this book, provided test sets for evaluating XML retrieval effectiveness. Many of the developments and results described in this book were investigated within INEX.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Today, computer-system optimization, at both the hardware and software levels, must consider the details of the memory system in its analysis; failing to do so yields systems that are increasingly inefficient as those systems become more complex. This lecture seeks to introduce the reader to the most important details of the memory system; it targets both computer scientists and computer engineers in industry and in academia. Roughly speaking, computer scientists are the users of the memory system and computer engineers are the designers of the memory system. Both can benefit tremendously from a basic understanding of how the memory system really works: the computer scientist will be better equipped to create algorithms that perform well and the computer engineer will be better equipped to design systems that approach the optimal, given the resource limitations. Currently, there is consensus among architecture researchers that the memory system is 'the bottleneck,' and this consensus has held for over a decade. Somewhat inexplicably, most of the research in the field is still directed toward improving the CPU to better tolerate a slow memory system, as opposed to addressing the weaknesses of the memory system directly. This lecture should get the bulk of the computer science and computer engineering population up the steep part of the learning curve. Not every CS/CE researcher/developer needs to do work in the memory system, but, just as a carpenter can do his job more efficiently if he knows a little of architecture, and an architect can do his job more efficiently if he knows a little of carpentry, giving the CS/CE worlds better intuition about the memory system should help them build better systems, both software and hardware.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book will be a key trailblazer in a new and upcoming field. The author's predictive approach relies on simple and intuitive probability formulations that will appeal to readers with a modest knowledge of astronomy, mathematics, and statistics. Wells' carefully erected theory stands on a sure footing and thus should serve as the basis of many rational predictions of survival in the face of not only natural disasters such as hits by asteroids or comets, but perhaps more surprisingly from man-made hazards arising from genetic engineering or robotics.Any formula for predicting human survival will invite controversy. Dr Wells counters anticipated criticism with a thorough approach in which four lines of reasoning are used to arrive at the same survival formula. One uses empirical survival statistics for business firms and stage shows. Another is based on uncertainty of risk rates. The third, more abstract, invokes Laplace's principle of insufficient reason and involves an observer's random arrival in the lifetime of the entity (the human race) in question. The fourth uses Bayesian theory.The author carefully explains and gives examples of the conditions under which his principle is valid and provides evidence that can counteract the arguments of critics who would reject it entirely. His deflection of possible criticisms results from two major premises: selecting the proper random variable and 'reference class' to make predictions, and the recognition that if one does not know the law that governs a process, then the best prediction that can be made is his own formula. 240 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The temporomandibular joint (TMJ) is a site of intense morbidity for millions of people, especially young, pre-menopausal women. Central to TMJ afflictions are the cartilaginous tissues of the TMJ, especially those of the disc and condylar cartilage, which play crucial roles in normal function of this unusual joint. Damage or disease to these tissues significantly impacts a patient's quality of life by making common activities such as talking and eating difficult and painful. Unfortunately, these tissues have limited ability to heal, necessitating the development of treatments for repair or replacement. The burgeoning field of tissue engineering holds promise that replacement tissues can be constructed in the laboratory to recapitulate the functional requirements of native tissues. This book outlines the biomechanical, biochemical, and anatomical characteristics of the disc and condylar cartilage, and also provides a historical perspective of past and current TMJ treatments and previous tissue engineering efforts. This book was written to serve as a reference for researchers seeking to learn about the TMJ, for undergraduate and graduate level courses, and as a compendium of TMJ tissue engineering design criteria.Table of Contents: The Temporomandibular Joint / Fibrocartilage of the TMJ Disc / Cartilage of the Mandibular Condyle / Tissue Engineering of the Disc / Tissue Engineering of the Mandibular Condyle / Current Perspectives 124 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Semi-supervised learning is a learning paradigm concerned with the study of how computers and natural systems such as humans learn in the presence of both labeled and unlabeled data. Traditionally, learning has been studied either in the unsupervised paradigm (e.g., clustering, outlier detection) where all the data are unlabeled, or in the supervised paradigm (e.g., classification, regression) where all the data are labeled. The goal of semi-supervised learning is to understand how combining labeled and unlabeled data may change the learning behavior, and design algorithms that take advantage of such a combination. Semi-supervised learning is of great interest in machine learning and data mining because it can use readily available unlabeled data to improve supervised learning tasks when the labeled data are scarce or expensive. Semi-supervised learning also shows potential as a quantitative tool to understand human category learning, where most of the input is self-evidently unlabeled. In this introductory book, we present some popular semi-supervised learning models, including self-training, mixture models, co-training and multiview learning, graph-based methods, and semi-supervised support vector machines. For each model, we discuss its basic mathematical formulation. The success of semi-supervised learning depends critically on some underlying assumptions. We emphasize the assumptions made by each model and give counterexamples when appropriate to demonstrate the limitations of the different models. In addition, we discuss semi-supervised learning for cognitive psychology. Finally, we give a computational learning theoretic perspective on semi-supervised learning, and we conclude the book with a brief discussion of open questions in the field.
