Buch. Condizione: Neu. Neuware - The design and development of electrical devices involves choosing from many possible variants that which is the best or optimum according to one or several criteria. These optimization criteria are usually already clear to the designer at the statement of the design problem. The methods of optimization considered in this book, allow us to sort out variants of the realization of a design on the basis of these criteria and to create the best device in the sense of the set criteria. Optimization of devices is one of the major problems in electrical engi neering that is related to an extensive class of inverse problems including synthesis, diagnostics, fault detection, identification, and some others with common mathematical properties. When designing a device, the engineer ac tually solves inverse problems by defining the device structure and its pa rameters, and then proceeds to deal with the technical specifications followed by the incorporation of his own notions of the best device. Frequently the so lutions obtained are based on intuition and previous experience. New meth ods and approaches discussed in this book will add mathematical rigor to these intuitive notions. By virtue of their urgency inverse problems have been investigated for more than a century. However, general methods for their solution have been developed only recently. An analysis of the scientific literature indicates a steadily growing interest among scientists and engineers in these problems.

Buch. Condizione: Neu. Neuware - As postal liberalization gains momentum, traditional postage meter markets are being transformed into digital meter markets for enterprise mailers.

Buch. Condizione: Neu. Neuware - Whatever its final readership and impact, we, the Editors, feel this book is im portant. It addresses the realisation that there is a deep and abiding synergy, albeit one only now being properly explored and exploited, between immunol ogy and computational science. This area of intersection we christen in silico immunology. Immunology is an inspiration for computational scientists seek ing practical and philosophical metaphors for their work; but, at the same time, it is itself a biological discipline of such discombobulating complexity that only computational help as different as simulation and data warehousing can make its modern study tractable. Thus immunology both inspires but also requires computational science. This book deals in detail with the three main areas of in silico immunology: theoretical immunology, immunoinformatics, and artificial immune systems. While all of these are now well-established the interactions between the three are only beginning to be developed. It is a truly exciting time to be working in in silicio immunology. We are reaching a critical mass that will enable great strides to be taken and significant achievements to be made. Like David Hume, we may yet come to regret that this book falls still born from the press but we hope not. Hopefully it will instead strike a cord and tap into a burgeoning Zeitgeist ready to capitalise on the remarkable potential that is in silico immunology.

Buch. Condizione: Neu. Neuware - Transport phenomena is used here to describe momentuin, energy, mass, and entropy transfer [1, 2]. It includes thermodynamics, a special case of which is thermosiaiics. Interfacial transport phenomena refers to momentum, energy, mass, and entropy transfer within the immediate neighborhood of a phase interface, including the thermodynamics of the interface. In terms of qualitative physical observations, this is a very old field. Pliny the Elder (Gains Plinius Secundus, 23-79 A. D. ; Pliny [3]) described divers who released small quantities of oil from their mouths, in order to damp capillary ripples on the ocean surface and in this way provide more uniform lighting for their work. Similar stories were retold by Benjamin Franklin, who conducted experiments of his own in England [4]. In terms of analysis, this is a generally young field. Surface thermostat ics developed relatively early, starting with Gibbs [5] and continuing with important contributions by many others (see Chap. 4). Derjaguin and Lan dau [6] and Verwey and Overbeek [7] indicated how London-van der Waals and electrostatic double-layer forces were to be incorporated in continuum mechanics, now often referred to as DLVO theory. But prior to 1960, there were relatively few notable papers concerned with the analysis of dynamic systems. Two stand out in my mind. Boussinesq [8] recognized the surface stress tensor and proposed the constitutive equation that we now refer to as the Boussinesq surface fluid model (Sect. 4. 9. 5).

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is widely recognized, by the scienti c and technical community that m- surements are the bridge between the empiric world and that of the abstract concepts and knowledge. In fact, measurements provide us the quantitative knowledge about things and phenomena. It is also widely recognized that the measurement result is capable of p- viding only incomplete information about the actual value of the measurand, that is, the quantity being measured. Therefore, a measurement result - comes useful, in any practicalsituation, only if a way is de ned for estimating how incomplete is this information. The more recentdevelopment of measurement science has identi ed in the uncertainty concept the most suitable way to quantify how incomplete is the information provided by a measurement result. However, the problem of how torepresentameasurementresulttogetherwithitsuncertaintyandpropagate measurementuncertaintyisstillanopentopicinthe eldofmetrology,despite many contributions that have been published in the literature over the years. Many problems are in fact still unsolved, starting from the identi cation of the best mathematical approach for representing incomplete knowledge. Currently, measurement uncertainty is treated in a purely probabilistic way, because the Theory of Probability has been considered the only available mathematical theory capable of handling incomplete information. However, this approach has the main drawback of requiring full compensation of any systematic e ect that a ects the measurement process. However, especially in many practical application, the identi cation and compensation of all s- tematic e ects is not always possible or cost e ective. 228 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Optimization under constraints is an essential part of everyday life. Indeed, we routinely solve problems by striking a balance between contradictory interests, individual desires and material contingencies. This notion of equilibrium was dear to thinkers of the enlightenment, as illustrated by Montesquieu's famous formulation: 'In all magistracies, the greatness of the power must be compensated by the brevity of the duration.'Astonishingly, natural laws are guided by a similar principle. Variational principles have proven to be surprisingly fertile. For example, Fermat used variational methods to demonstrate that light follows the fastest route from one point to another, an idea which came to be known as Fermat's principle, a cornerstone of geometrical optics. Variational Principles in Physics explains variational principles and charts their use throughout modern physics. The heart of the book is devoted to the analytical mechanics of Lagrange and Hamilton, the basic tools of any physicist. Prof. Basdevant also offers simple but rich first impressions of Einstein's General Relativity, Feynman's Quantum Mechanics, and more revealing and amazing interconnections between various fields of physics. 196 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Subsistence intensification, innovation and change have long figured prominently in explanations for the development of social complexity among foragers and horticulturalists, and the rise of chiefly societies and archaic states, yet there is considerable debate over the actual mechanisms that promote these processes. Traditional approaches to the 'intensification question' emphasize population pressure, climate change, bureaucratic management, or even land degradation as prerequisites for the onset of new or changing strategies, or the construction and maintenance of agricultural landscapes. Most often these factors are modeled as external forces outside the realm of human decision-making, but recent archaeological research presents an alternative to this suggesting that subsistence intensification is the result of human driven strategies for power, prestige and status stemming from internal conditions within a group. When responding to environmental adversity, human groups were less frequently the victims, as they have been repeatedly portrayed. Instead human groups were often vigorous actors, responding with resilience, ingenuity, and planning, to flourish or survive within dynamic and sometimes unpredictable social and natural milieux.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The Goodwin-Niering Center for Conservation Biology and Environmental Studies at Connecticut College is a comprehensive, interdisciplinary program that builds on one of the nation's leading undergraduate environmental studies programs. The Center fosters research, education and curriculum development aimed at under standing contemporary ecological challenges. One of the major goals of the Good win-Niering Center involves enhancing the understanding of both the College com munity and the general public with respect to ecological, political, social, and economic factors that affect natural resource use. To this end, the Center has offered five conferences at which academicians, representatives of federal and state govern ment, and individuals from non-government environmental organizations are brought together for an in-depth, interdisciplinary evaluation of important environ mental issues. On April 1 and 2, 2005, the Center presented the Elizabeth Babbott Conant interdisciplinary conference on Acid in the Environment: Lessons Learned and Future Prospects. The Connecticut Institute of Water Resources at the Univer sity of Connecticut, the Connecticut Chapter of The Nature Conservancy and the Connecticut Sea Grant College Program joined the Center as conference sponsors. During the past twenty five years acid rain, formally referred to as acid deposi tion, has been the focus of much political debate and scholarly research. Acid dep osition occurs when important precursor pollutants, such as sulfur dioxide (SO2) and nitrogen oxides (NO^), mix with water vapor and oxidants in the atmosphere and fall back to earth in either wet or dry form.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 352 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Research on Computer-Supported Collaborative Learning (CSCL) is a multidisciplinary field located at the intersection of cognitive psychology, computer science, and education. Yet, the different epistemological and theoretical backgrounds of these disciplines often make fruitful exchange between them difficult. CSCL urgently needs to develop and use boundary concepts that can bring these fields closer together to improve cumulative research and development of computer-supported learning environments. Scripting Computer-Supported Collaborative Learning focuses on one term with the potential to become a real boundary concept in CSCL-'scripting'.Scripting Computer-Supported Collaborative Learning, which has collected advanced script approaches, demonstrates the opportunities for using synergy to apply the script concept between perspectives and interdisciplinary CSCL approaches to scripting.This volume represents the state of the art of research on scripting computer-supported collaborative learning and provides a starting point for the development of a common understanding of scripting in CSCL. Research on collaboration scripts has an extraordinary potential for advancing the multidisciplinary endeavor of CSCL research and this book provides a rich basis for further exploring and realizing this potential. As such, it will be a valuable resource for research, development, and teaching. 344 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Linear Genetic Programming presents a variant of genetic programming (GP) that evolves imperative computer programs as linear sequences of instructions, in contrast to the more traditional functional expressions or syntax trees. Primary characteristics of linear program structure are exploited to achieve acceleration of both execution time and evolutionary progress. Online analysis and optimization of program code lead to more efficient techniques and contribute to a better understanding of the method and its parameters. In particular, the reduction of structural variation step size and non-effective variations play a key role in finding higher quality and less complex solutions. Typical GP phenomena, such as non-effective code, neutral variations, and code growth are investigated from the perspective of linear GP.This book serves as a reference for researchers; it also contains sufficient introductory material for students and those who are new to the field. 315 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Among the themes that have been central to mathematics education dur ing the last 30 years are those of mathematical modelling and applications of mathematics to extra-mathematical fields. More generally we refer to these as relations between mathematics and the extra-mathematical world (some times also called the 'real world') or preferably, according to Henry PoUak, the 'rest of the world'. That applications and modelling have been important themes in mathematics education can be inferred from the wealth of litera ture on these topics, including material generated from a multitude of na tional and international conferences. In particular let us mention firstly the ICMEs (the International Congresses on Mathematical Education), with their regular working or topic groups and lectures on applications and modelling; and secondly the series of ICTMAs (the International Conferences on the Teaching of Mathematical Modelling and Applications) which have been held biennially since 1983. Their Proceedings and Survey Lectures, have addressed the state-of-the-art at the relevant time, and contain many exam ples, studies, conceptual contributions and resources involving relations between the real world and mathematics, for all levels of the educational system. In curricula and textbooks we find today many more references to real world phenomena and problems than, say, twenty years ago. 540 pp. Englisch.
