Taschenbuch. Condición: Neu. Neuware -They Play, You Pay is a detailed, sometimes irreverent look at a political conundrum: despite evidence that publicly funded ballparks, stadiums, and arenas do not generate net economic growth, governments keep on taxing sales, restaurant patrons, renters of automobiles, and hotel visitors in order to build ever more elaborate cathedrals of professional sport¿often in order to satisfy an owner who has threatened to move his team to greener, more subsidy¿happy, pastures. This book is a sweeping survey of the literature in the field, the history of such subsidies, the politics of stadium construction and franchise movement, and the prospects for a re¿privatization of ballpark and stadium financing. It ties together disparate strands in a fascinating story, examining the often colorful cases through which governments became involved in sports. These range from the well¿known to the obscure¿from Yankee Stadium and the Astrodome to the Brooklyn Dodgers¿ move to Los Angeles (to a privately built ballpark constructed upon land that had been seized via eminent domain from a mostly Mexican¿American population) to such arrant giveaways as Cowboys Stadium. It examines alternatives that might lessen the pressure for public subsidies, whether the Green Bay Packers model (in which the team¿s owners are local stockholders) or via league expansions. It also takes a look at little-known, yet significant, episodes such as President Theodore Roosevelt¿s intervention in the collegiate football crisis of 1905¿a move that indirectly put the federal government on the side of such basic rule changes as the legalization of the forward pass.They Play, You Play is a fresh look at a political and economic puzzle: how it came to be that Joe and Jane Sixpack in the Bronx and Dallas subsidize the Steinbrenners and Jerry Joneses of professional sport.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Englisch.

Buch. Condición: Neu. Neuware -Case Studies in Service Innovation provides the reader fresh insight into how innovation occurs in practice, and stimulates learning from one context to another. The volume brings together contributions from researchers and practitioners in a celebration of achievements with the intention of adding to the wider understanding of how service innovation develops. Each case presents a brief description of the context in which the innovation occurred, the opportunity that led to the innovation and an overview of the innovation itself, also addressing how success was measured, what success has been achieved to date and providing links to further information.The book is organized around five major themes, each reflecting recognized sources of service innovation: Business Model Innovation: new ways of creating, delivering or capturing economic, social, environmental and other types of value; The Organization in its Environment: an organization engaging beyond its own boundaries, with public private partnerships, sourcing knowledge externally, innovation networks, and open or distributed innovation; Innovation Management within an Organization: an organization actively encouraging innovation within its own boundaries using project teams, internal governance of innovation, and methods or tools that stimulate innovation; Process Innovation: changes in service design and delivery processes, such as consumer led innovation or consumers as part of the innovation process, service operations management, and educational processes; Technology Innovation: the use of technology, including ICT enabled innovation, ICTs that are themselves innovative and support the delivery of new services, new ICT services, new ways of delivering services associated with ICT products, and technology other than ICT.The final part of the book is given to four extended cases allowing for a more in-depth treatment of innovation within a complex service system. The extended cases also illustrate two important and growing trends, firstly the need for, and benefits of, a more customer centric approach to service innovation and secondly the need for better understanding of public services and the role of public-private partnerships in identifying and achieving innovation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Inferring gene regulatory networks is a difficult problem to solve due to the relative scarcity of data compared to the potential size of the networks. While researchers have developed techniques to find some of the underlying network structure, there is still no one-size-fits-all algorithm for every data set.Network Inference in Molecular Biology examines the current techniques used by researchers, and provides key insights into which algorithms best fit a collection of data. Through a series of in-depth examples, the book also outlines how to mix-and-match algorithms, in order to create one tailored to a specific data situation.Network Inference in Molecular Biology is intended for advanced-level students and researchers as a reference guide. Practitioners and professionals working in a related field will also find this book valuable.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 112 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Vibrational spectroscopy techniques, which have traditionally been used to provide non-destructive, rapid, and relevant information on microbial systematics, are useful for classification and identification. In conjunction with advanced chemometrics, infrared spectroscopy enables the biochemical signatures from microbiological structures to be extracted and analysed. In addition, a number of recent studies have shown that Fourier Transform Infrared (FT-IR) spectroscopy can help to understand the molecular basis of events, such as the adaptive tolerance responses expressed by bacteria when exposed to stress conditions in the environment, i.e. environments that cells confront in food and during food processing. The proposed Brief will discuss the published experimental techniques, data-processing algorithms, and approaches used in FT-IR spectroscopy to assist in the characterization and identification of microorganisms, to assess the mechanisms of bacterial inactivation by food processing technologies and antimicrobial compounds, to monitor the spore and membrane properties of foodborne pathogens in changing environments, to detect stress-injured microorganisms in food-related environments, to assess dynamic changes in bacterial populations, and to study bacterial tolerance responses.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 64 pp. Englisch.

Buch. Condición: Neu. Qvennerstedt, Olle Ilustrador. Neuware -The term ¿Peak Oil¿ was born in January 2001 when Colin Campbell formed the Association for the Study of Peak Oil & Gas (ASPO). Now, Peak Oil is used thousands of times a day by journalists, politicians, industry leaders, economists, scientists and countless others around the globe. Peak Oil is not the end of oil but it tells us the end is in sight. Anyone interested in food production, economic growth, climate change or global security needs to understand this new reality.In Peeking at Peak Oil Professor Kjell Aleklett, President of ASPO International and head of the world¿s leading research group on Peak Oil, describes the decade-long journey of Peak Oil from extremist fringe theory to today¿s accepted fact: Global oil production is entering terminal decline. He explains everything you need to know about Peak Oil and its world-changing consequences from an insider¿s perspective. In simple steps, Kjell tells us how oil is formed, discovered and produced. He uses science to reveal the errors and deceit of national and international oil authorities, companies and governments too terrified to admit the truth. He describes his personal involvement in the intrigues of the past decade.What happens when a handful of giant oil fields containing two thirds of our planet¿s oil become depleted Will major oil consumers such as the EU and US face rationing within a decade Will oil producing nations conserve their own oil when they realize that no one can export oil to them in the future Does Peak Oil mean Peak Economic Growth If you want to know the real story about energy today and what the future has in store, then you need to be ¿Peeking at Peak Oil¿.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Ten years ago the Sunnner Institute on 'Trends in Particle The ory' was held in Bonn. Among other subj ects J. Wess spoke on his work wi th B. ZlDllino on 'Fermi - Bose-Supersymmetry'. In the meantime this subject has developed into one of the most exciting fields of research and the Bonn Summer Institute (August 20 - August 31 1984) was devoted exclusively to supersymmetry. The main aim of the Summer Institute was to provide a compre hensive introduction for mainly young post-doctoral theoretical physicists to the currently most discussed subjects in supersynnne try and supergravity. The intention was to emphasize the pedagogi cal presentation. The seminars given in addition to the introduc tory lectures treat more specialized subjects and are closer to research reports. Since the topics, ranging fromalgebraic structures to experimental implications do not arrange easily in a one-dimension al array, the lectures are reproduced in alphabetic order of the lec turers. The Summer Institute was made possible by the NATO Advanced Study Programme, additional support was granted by the Bundesmi nisterium für Forschung und Technologie and the Ministerium für Wissenschaft und Forschung of Nordrhein-Westfalen. We gratefully acknowledge their cooperation. It is a pleasure to thank the lecturers and seminar speakers for the effort invested in the presentation of the lectures and in their collaboration in preparing the written notes.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 720 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -For well over a decade, the numerical approach to field computation has been gaining progressively greater importance. Analytical methods of field compu tation are, at best, unable to accommodate the very wide variety of configura tions in which fields must be computed. On the other hand, numerical methods can accommodate many practical configurations that analytical methods cannot. With the advent of high-speed digital computers, numerical field computations have finally become practical. However, in order to implement numerical methods of field computation, we need algorithms, numerical methods, and mathematical tools that are largely quite different from those that have been traditionally used with analytical methods. Many of these algorithms have, in fact, been presented in the large number of papers that have been published on this subject in the last two decades. And to some of those who are already experienced in the art of numerical field computations, these papers, in addition to their own original work, are enough to give them the knowledge that they need to perform practical numerical field computations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Supercomputers are the largest and fastest computers available at any point in time. The term was used for the first time in the New York World, March 1920, to describe 'new statistical machines with the mental power of 100 skilled mathematicians in solving even highly complex algebraic problems. ' Invented by Mendenhall and Warren, these machines were used at Columbia University'S Statistical Bureau. Recently, supercomputers have been used primarily to solve large-scale prob lems in science and engineering. Solutions of systems of partial differential equa tions, such as those found in nuclear physics, meteorology, and computational fluid dynamics, account for the majority of supercomputer use today. The early computers, such as EDVAC, SSEC, 701, and UNIVAC, demonstrated the feasibility of building fast electronic computing machines which could become commercial products. The next generation of computers focused on attaining the highest possible computational speeds. This book discusses the architectural approaches used to yield significantly higher computing speeds while preserving the conventional, von Neumann, machine organization (Chapters 2-4). Subsequent improvements depended on developing a new generation of computers employing a new model of computation: single-instruction multiple data (SIMD) processors (Chapters 5-7). Later machines refmed SIMD architec ture and technology (Chapters 8-9). SUPERCOMPUTER ARCHITECI'URE CHAPTER! INTRODUCTION THREE ERAS OF SUPERCOMPUTERS Supercomputers -- the largest and fastest computers available at any point in time -- have been the products of complex interplay among technological, architectural, and algorithmic developments.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Ten years after the publication of the first edition of Flllldmntntais of Food Process Engineering, there have been significant changes in both food science education and the food industry itself. Students now in the food science curric ulum are generally better prepared mathematically than their counterparts two decades ago. The food science curriculum in most schools in the United States has split into science and business options, with students in the science option following the Institute of Food Technologists' minimum requirements. The minimum requirements include the food engineering course, thus students en rolled in food engineering are generally better than average, and can be chal lenged with more rigor in the course material. The food industry itself has changed. Traditionally, the food industry has been primarily involved in the canning and freezing of agriCUltural commodi ties, and a company's operations generally remain within a single commodity. Now, the industry is becoming more diversified, with many companies involved in operations involving more than one type of commodity. A number of for mulated food products are now made where the commodity connection becomes obscure. The ability to solve problems is a valued asset in a technologist, and often, solving problems involves nothing more than applying principles learned in other areas to the problem at hand. A principle that may have been commonly used with one commodity may also be applied to another commodity to produce unique products. 624 pp. Englisch.

Buch. Condición: Neu. Neuware -Archaeology of Spiritualties provides a fresh exploration of the interface between archaeology and religion/spirituality. Archaeological approaches to the study of religion have typically and often unconsciously, drawn on western paradigms, especially Judaeo-Christian (mono) theistic frameworks and academic rationalisations. Archaeologists have rarely reflected on how these approaches have framed and constrained their choices of methodologies, research questions, hypotheses, definitions, interpretations and analyses and have neglected an important dimension of religion: the human experience of the numinous - the power, presence or experience of the supernatural.Within the religions of many of the world¿s peoples, sacred experiences ¿ particularly in relation to sacred landscapes and beings connected with those landscapes ¿ are often given greater emphasis, while doctrine and beliefs are relatively less important. Archaeology of Spiritualities asks how such experiences might be discerned in the archaeological record; how do we recognize and investigate ¿other¿ forms of religious or spiritual experience in the remains of the past .The volume opens up a space to explore critically and reflexively the encounter between archaeology and diverse cultural expressions of spirituality. It showcases experiential and experimental methodologies in this area of the discipline, an unconventional approach within the archaeology of religion. ThusArchaeology of Spiritualities offers a unique, timely and innovative contribution, one that is alsochallenging and stimulating. It is a great resource to archaeologists, historians, religious scholars and others interested in cultural and religious heritage.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 296 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This book describes the technology, history, and future of rocket planes. Michel van Pelt journies into this exciting world, examining the exotic concepts and actual flying vehicles that have been devised over the last hundred years. He recounts the history of rocket airplanes, from the early pioneers who attached simple rockets onto their wooden glider airplanes to the modern world of high-tech research vehicles. The author visits museums where rare examples of early rocket planes are kept and modern laboratories where future spaceplanes are being developed. He explains the technology in an easily understandable way, describing the various types of rocket airplanes and looking at the possibilities for the future.Michel van Pelt considers future spaceplanes, presenting various modern concepts and developments. He describes the development from cutting edge research via demonstrator vehicles to operational use. He also evaluates the replacement of the Space Shuttle with a seemingly old-fashioned capsule system, the parallel developments in suborbital spaceplanes such as SpaceShipOne and SpaceShipTwo, piloted versus automatic flight, and related developments in airliners and military aircraft.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 384 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Fifteen years have elapsed after the second edition of Practical Bifurcation and Stability Analysis was published. During that time period the eld of computational bifurcation has become mature. Today, bifurcation mec- nisms are widely accepted as decisive phenomena for explaining and - derstanding stability and structural change. Along with the high level of sophistication that bifurcation analysis has reached, the research on basic computational bifurcation algorithms is essentially completed, at least in - dinary di erential equations. The focus has been shifting from mathematical foundations towards applications. The evolution from equilibrium to chaos has become commonplace and is no longer at the cutting edge of innovation. But the corresponding methods of practical bifurcation and stability analysis remain indispensable instruments in all applications of mathematics. This constant need for practical bifur- tion and stability analysis has stimulated an e ort to maintain this book on a present-day level. The author¿s endeavor has resulted in this third edition. It is based on more than three decades of practical experience with the subject, and on many courses given at several universities.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 504 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Almost 12 years have passed by since we wrote Chaos and Fractals. At the time we were hoping that our approach of writing a book which would be both accessible without mathematical sophistication and portray these exiting new fields in an authentic manner would find an audience. Now we know it did. We know from many reviews and personal letters that the book is used in a wide range of ways: researchers use it to acquaint themselves, teachers use it in college and university courses, students use it for background reading, and there is also a substantial audience of lay people who just want to know what chaos and fractals are about. Every book that is somewhat technical in nature is likely to have a number of misprints and errors in its first edition. Some of these were caught and brought to our attention by our readers. One of them, Hermann Flaschka, deserves to be thanked in particular for his suggestions and improvements. This second edition has several changes. We have taken out thetwo appendices from the firstedition. At the time of the first edition Yuval Fishers contribution, which we published as an appendix was probably the first complete expository account on fractal image compression. Meanwhile, Yuvals book Fractal Image Compression: Theory and Application appeared and is now the publication to refer to.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 904 pp. Englisch.

Buch. Condición: Neu. Neuware -Several natural Lp spaces of analytic functions have been widely studied in the past few decades, including Hardy spaces, Bergman spaces, and Fock spaces. The terms ¿Hardy spaces¿ and ¿Bergman spaces¿ are by now standard and well established. But the term ¿Fock spaces¿ is a different story.Numerous excellent books now exist on the subject of Hardy spaces. Several books about Bergman spaces, including some of the author¿s, have also appeared in the past few decades. But there has been no book on the market concerning the Fock spaces. The purpose of this book is to fill that void, especially when many results in the subject are complete by now. This book presents important results and techniques summarized in one place, so that new comers, especially graduate students, have a convenient reference to the subject.This book contains proofs that are new and simpler than the existing ones in the literature. In particular, the book avoids the use of the Heisenberg group, the Fourier transform, and the heat equation. This helps to keep the prerequisites to a minimum. A standard graduate course in each of real analysis, complex analysis, and functional analysis should be sufficient preparation for the reader.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Ludwig Prandtl, with his fundamental contributions to hydrodynamics, ae- dynamics, and gas dynamics, greatly in uenced the development of uid - chanics as a whole, and it was his pioneering research in the rst half of the last century that founded modern uid mechanics. His book Führer durch die Str¿omungslehre, which appeared in 1942, originated from previous pub- cations in 1913, Lehre von der Flüssigkeit und Gasbewegung, and 1931, Abriß der Str¿omungslehre. The title Führer durch die Str¿omungslehre, or Essentials of Fluid Mechanics, is an indication of Prandtl¿s intentions to guide the reader on a carefully thought-out path through the di erent areas of uid mech- ics. On his way, the author advances intuitively to the core of the physical problem, without extensive mathematical derivations. The description of the fundamental physical phenomena and concepts of uid mechanics that are needed to derive the simpli ed models has priority over a formal treatment of the methods. This is in keeping with the spirit of Prandtl¿s research work. The rst edition of Prandtl¿s Führer durch die Str¿omungslehre was the only book on uid mechanics of its time and, even today, counts as one of the most important books in this area. After Prandtl¿s death, his students Klaus Oswatitsch and Karl Wieghardt undertook to continue his work, and to add new ndings in uid mechanics in the same clear manner of presentation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 808 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware - Volume 3 continues the approach carried out in the first two volumes of this se ries of publishing articles on membrane methodology which include, in addition to procedural details, incisive discussions of the ap plications of the methods and of their limitations. Wh at is the theoretical basis of the method, how and to what problems can it be applied, how does one interpret the results, what has thus far been achieved by the method, what lies in the future-these are the questions the authors have tried to answer. No area of membrane biology engages the interest of more investigators than studies of the plasma membrane. Four chapters in this volume are concerned with one or more aspects of the cell surface. Fundamental to all studies of the cell surface are the isolation and characterization of pure plasma membranes. Many preparations described in the literature are inadequate or are inadequately characterized. In the first chapter, Neville discusses the theoretical and practical bases of tissue fractionation, empha sizes the variations in enzyme content among plasma membranes from different sources, offers guidance in the choice of the proper criteria for assessing membrane purity, and suggests the best markers for detecting the possible presence of contaminating organelles. To review in detail each of the many preparations of plasma membranes that have been published is impossible.

Neuware - Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) \* at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Taschenbuch. Condición: Neu. Neuware - This volume continues the tradition of SUBCELLULAR BIOCHEMISTRY of trying to break down interdisciplinary barriers in the study of cell function and of bringing the reader's attention to less well studied, but nevertheless useful, biological systems. We start with an extensive article by T. P. Karpetsky, M. S. Boguski and C. C. Levy on the structure, properties and possible functions of polyadenylic acid. Apart from revealing a general lack of appreciation of many important aspects of the chemical properties of poly adenylic acid, the literature also shows that there is a great gulf between those who study the biological role of polyadenylic acid. and those who study its physicochemi cal properties. The article by Karpetsky and his colleagues is an attempt to overcome this lack of communication and to present an integrated view of the subject. The authors go into the subject in full detail and the more biologically inclined reader may on occasion have to reread his nucleic acid physical chemistry notes! However, the effort is worthwhile and the article is a timely reminder that we cannot treat nucleic acids as mere abstractions, but that they are complex organic macromolecules capable of equally complex, but nevertheless important, interactions. The next article is by J. Steensgaard and N. P. Hundahl M0ller and deals with computer simulation of density gradient centrifugation systems.

Taschenbuch. Condición: Neu. Neuware - The first volume of Evolutionary Biology was published thirteen years ago. Since that time thirteen volumes and one supplement have appeared. As stated in earlier prefaces, we are continuing the focus of this series on critical reviews, commentaries, original papers, and controversies in evolu tionary biology. It is our aim to publish papers primarily of greater length than normally published by society journals and quarterlies. We therefore invite colleagues to submit chapters that fall within the focus and standards of Evolutionary Biology. The editors regretfully announce that Dr. William C. Steere has decided to withdraw from the editorial board of Evolutionary Biology. Dr. Ghillean T. Prance will replace Dr. Steere for forthcoming volumes.

Taschenbuch. Condición: Neu. Neuware - Evolutionary Biology, of which this is the twenty-first volume, continues to offer its readers a wide range of original articles, reviews, and com mentaries on evolution, in the broadest sense of that term. The topics of the reviews range from anthropology and behavior to molecular biology and systematics. In recent volumes, a broad spectrum of articles have appeared on such subjects as evolution of the bacterial genome, biochemical system atics in plants, a discussion of species selection, and development and evolution of the vertebrate limb. Articles such as these, often too long for standard journals, are the material for Evolutionary Biology. The editors continue to solicit manuscripts on an international scale in an effort to see that everyone ofthe many facets of biological evolution is covered. Manuscripts should be sent to anyone of the following: Max K.

Taschenbuch. Condición: Neu. Neuware - This is the third volume of the comprehensive series on Struc ture and Function of the Circulation, edited by Dr. Colin J. Schwartz with the collaboration of Nicholas T. Werthessen and Stewart Wolf. Dr. Schwartz, an authority on vascular structure and function and a respected investigator in this field for many years, selected as authors for the chapters an outstanding group of scientists from various parts of the world. As indicated in the Preface, the impetus for this broad treat ise evolved from the scientific sessions of three interdisciplinary international conferences held in Lindau in 1970, in Heidelberg in 1973, and Totts Gap, Pennsylvania, in 1976 as well as from numerous informal discussions. The subjects dealt with in these three volumes range from the roots of our knowledge in ancient history to the most recent inform ation on contractile proteins of smooth muscle cells. The structure, distribution, and dynamics of arteries, veins, and lymphatics are described in chapters on the systemic circulation as well as that of the heart, the vessels themselves, the brain, nerves, and viscera. Descriptions of ultrastructure, histochemistry, metabolism, and func tion of endothelium and of vascular smooth muscle and of vascular changes in aging are all included in the vast scope of this under taking.

Buch. Condición: Neu. Neuware -Technology and Household Consumption is a comprehensive text that provides insights into technology¿s impact on consumer behavior and the household environment. Consumption and consumer behavior has become a very important subject of study that is now covered in many disciplines including family economics, culture studies, and feminist/women studies.In the first section, this book provides a historical perspective on how consumer behaviors have changed because of technology and how technology itself has changed. Data on ownership and expenditures is detailed in describing the penetration of technology in the household and changes over time. In the examination of demographics and social changes, an emphasis is placed on women and children. As it is important to understand the entry paths and factors that influence them, the book also introduces a research framework to understanding the adoption and utilization of household technologies.

Buch. Condición: Neu. Neuware -In a computational tour-de-force, this volume wipes away a host of problems related to location discovery in wireless ad-hoc sensor networks. WASNs have recognized potential in many applications that are location-dependent, yet are heavily constrained by factors such as cost and energy consumption. Their ¿ad-hoc¿ nature, with direct rather than mediated connections between a network of wireless devices, adds another layer of difficulty.Basing this work entirely on data-driven, coordinated algorithms, the author¿s aim is to present location discovery techniques that are highly accurate¿and which fit user criteria. The research deploys nonparametric statistical methods and relies on the concept of joint probability to construct error (including location error) models and environmental field models. It also addresses system issues such as the broadcast and scheduling of the beacon. Reporting an impressive accuracy gain of almost 17 percent, and organized in a clear, sequential manner, this book represents a stride forward in wireless localization.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Buch. Condición: Neu. Neuware -The primary purpose in this book is to present an integrated and innovative methodological approach for the construction and selection of equity portfolios. The approach takes into account the inherent multidimensional nature of the problem, while allowing the decision makers to incorporate specified preferences in the decision processes. A fundamental principle of modern portfolio theory is that comparisons between portfolios are generally made using two criteria; the expected return and portfolio variance. According to most of the portfolio models derived from the stochastic dominance approach, the group of portfolios open to comparisons is divided into two parts: the efficient portfolios, and the dominated. This work integrates the two approaches providing a unified model for decision making in portfolio management with multiple criteria.¿Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 140 pp. Englisch.

Buch. Condición: Neu. Neuware -This book describes methods to design distributed amplifiers useful for performing circuit functions such as duplexing, paraphrase amplification, phase shifting power splitting and power combiner applications. A CMOS bidirectional distributed amplifier is presented that combines for the first time device-level with circuit-level linearization, suppressing the third-order intermodulation distortion. It is implemented in 0.13um RF CMOS technology for use in highly-linear, low-cost UWB Radio-over-Fiber communication systems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 160 pp. Englisch.
