Taschenbuch. Condizione: Neu. Neuware -Die regenerativen Energietrager haben bereits heute einen signifikanten Anteil an der weltweiten Stromerzeugung. 1m Jahre 1997 trugen sie knapp 20 % zur Gesamt produktion von etwa 12. 000 TWh bei. Dieser Anteil wurde fast ausschlieBlich von der Wasserkraft gedeckt, der Beitrag der Solarthermie war mit 0,7 TWh sehr klein, obwohl bereits Ende des letzten, Anfang dieses Jahrhunderts erste Anlagen u. a. zum Antrieb von Bewasserungspumpen auf Basis solarthermischer Stromerzeugung gebaut wurden. Der Einsatz von kostengtinstigerem 01 und anderen fossilen Brenn stoffen verhinderte damals weitere Entwicklungen, und erst mit dem Beginn der Energiekrise 1973/74 wurden diese Technologien neu entdeckt. Wahrend die Para bolrinnenkraftwerke SEGS I-IX mit 354 MWel in Kalifornien schon bewiesen, daB unter gtinstigen Rahmenbedingungen ein kommerzieHer Betrieb moglich ist, bieten z. B. Paraboloidkraftwerke mit im Brennpunkt angeordneten Stirling-Motoren erst die Perspektive, bei Serienfertigung Strom in abgelegenen Gebieten des aquatoria len Gtirtels giinstiger zu gestehen als die dort bisher genutzten Dieselaggregate. ABe solarthermischen Anlagen erfordern eine direkte Einstrahlung von mindestens 2 1800 kWh/m a, so daB ihr Einsatz nur in Gebieten zwischen etwa 40° nordlicher und siidlicher Breite, also beispielsweise nicht in Deutschland, okonomisch sinnvoH ist. Das hier vorliegende Buch ist aus dem Skriptum zur Vorlesung 'Stromerzeugung durch erneuerbare Energietrager', weche an der Ruhr-Universitat Bochum seit dem Wintersemester 1996 als Wahlfach bzw. als Teilnahmefach der Vertiefungsrichtung 'Energieversorgung' gelesen wird, hervorgegangen. 192 pp. Deutsch.…

Taschenbuch. Condizione: Neu. Neuware - Dieses moderne Lehrbuch ist aus Vorlesungen und Übungen der Verfasser zur Theorie des elektromagnetischen Feldes (Elektromagnetik) und zur Höheren Mathematik hervorgegangen. Da die Technik vom Ingenieur immer umfassendere und tiefere mathematische und theoretische Kenntnisse verlangt, gehen die Autoren über den üblichen Vorlesungsstoff der Grundkurse hinaus und stellen insbesondere die Themen Variations- und Tensorrechnung voran. Es wird ein neuer -für den Ingenieur unüblicher Weg- gegangen, indem sie aus dem Prinzip der kleinsten Wirkung mittels der vorgenannten Rechnungen die Maxwellschen Gleichungen herleiten. Durch die Voranstellung von Relativitätsprinzip und dem Prinzip von der Konstanz der Lichtgeschwindigkeit erhält der Leser einen einfachen Einstieg in relativistische Betrachtungen.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The study of the genetic basis for evolution has flourished in this century, as well as our understanding of the evolvability and programmability of biological systems. Genetic algorithms meanwhile grew out of the realization that a computer program could use the biologically-inspired processes of mutation, recombination, and selection to solve hard optimization problems. Genetic and evolutionary programming provide further approaches to a wide variety of computational problems. A synthesis of these experiences reveals fundamental insights into both the computational nature of biological evolution and processes of importance to computer science. Topics include biological models of nucleic acid information processing and genome evolution; molecules, cells, and metabolic circuits that compute logical relationships; the origin and evolution of the genetic code; and the interface with genetic algorithms and genetic and evolutionary programming. 352 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The purpose of these lecture notes is to develop a theory of asymptotic expansions for functions involving two variables, while at the same time using functions involving one variable and functions of the quotient of these two variables. Such composite asymptotic expansions (CAsEs) are particularly well-suited to describing solutions of singularly perturbed ordinary differential equations near turning points. CAsEs imply inner and outer expansions near turning points. Thus our approach is closely related to the method of matched asymptotic expansions. CAsEs offer two unique advantages, however. First, they provide uniform expansions near a turning point and away from it. Second, a Gevrey version of CAsEs is available and detailed in the lecture notes. Three problems are presented in which CAsEs are useful. The first application concerns canard solutions near a multiple turning point. The second application concerns so-called non-smooth or angular canard solutions. Finally an Ackerberg-O'Malley resonance problem is solved. 176 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This research monograph provides a pedagogical and self-contained introduction to non-equilibrium quantum particle dynamics for inhomogeneous systems, up to and including a survey of recent breakthroughs pioneered by the authors and other groups. The theoretical approach is based on real-time Green's functions (Keldysh Green's functions), directly solving the two-time Kadanoff-Baym equations (KBE). This field has seen a rapid development over the last decade, with new applications emerging in plasma physics, semiconductor optics and transport, nuclear matter and high-energy physics. This text will be a valuable starting point and reference work for graduate students and researchers interested in the quantum dynamics of inhomogeneous systems. 144 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph derives direct and concrete relations between colored Jones polynomials and the topology of incompressible spanning surfaces in knot and link complements. Under mild diagrammatic hypotheses, we prove that the growth of the degree of the colored Jones polynomials is a boundary slope of an essential surface in the knot complement. We show that certain coefficients of the polynomial measure how far this surface is from being a fiber for the knot; in particular, the surface is a fiber if and only if a particular coefficient vanishes. We also relate hyperbolic volume to colored Jones polynomials.Our method is to generalize the checkerboard decompositions of alternating knots. Under mild diagrammatic hypotheses, we show that these surfaces are essential, and obtain an ideal polyhedral decomposition of their complement. We use normal surface theory to relate the pieces of the JSJ decomposition of the complement to the combinatorics of certain surface spines (state graphs). Since state graphs have previously appeared in the study of Jones polynomials, our method bridges the gap between quantum and geometric knot invariants. 184 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Clustering is an important unsupervised classification technique where data points are grouped such that points that are similar in some sense belong to the same cluster. Cluster analysis is a complex problem as a variety of similarity and dissimilarity measures exist in the literature.This is the first book focused on clustering with a particular emphasis on symmetry-based measures of similarity and metaheuristic approaches. The aim is to find a suitable grouping of the input data set so that some criteria are optimized, and using this the authors frame the clustering problem as an optimization one where the objectives to be optimized may represent different characteristics such as compactness, symmetrical compactness, separation between clusters, or connectivity within a cluster. They explain the techniques in detail and outline many detailed applications in data mining, remote sensing and brain imaging, gene expression data analysis, and face detection.The book will be useful to graduate students and researchers in computer science, electrical engineering, system science, and information technology, both as a text and as a reference book. It will also be useful to researchers and practitioners in industry working on pattern recognition, data mining, soft computing, metaheuristics, bioinformatics, remote sensing, and brain imaging. 280 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This open access book.There is significant interest in the Philosophy of Science community to understand the role that 'effective theories' have in the work of forefront science. The ideas of effective theories have been implicit in science for a long time, but have only been articulated well in the last few decades. Since Wilson's renormalization group revolution in the early 1970's, the science community has come to more fully understand its power, and by the mid-1990's it had gained its apotheosis. It is still one of the most powerful concepts in science, which has direct impact in how one thinks about and formulates theories of nature. It is this power that this Brief sets out to emphasize through historical analysis and current examples.This is an open access book. 88 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For centuries, natural law was the main philosophical legal paradigm. Now, it is a wonder when a court of law invokes it. Arthur Kaufmann already underlined a modern general 'horror iuris naturalis'. We also know, with Winfried Hassemer, that the succession of legal paradigms is a matter of fashion. But why did natural law become outdated Are there any remnants of it still alive today This book analyses a number of prejudices and myths that have created a general misconception of natural law. As Jean-Marc Trigeaud put it: there is a natural law that positivists invented. Not the real one(s). It seeks to understand not only the usual adversaries of natural law (like legalists, positivists and historicists) but also its further enemies, the inner enemies of natural law, such as internal aporias, political and ideological manipulations, etc. The book puts forward a reasoned and balanced examination of this treasure of western political and juridical though. And, if we look at it another way, natural law is by no means a loser in our times: because it lives in modern human rights. 88 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The highly developed industrial countries today have to face the challenge of accelerated structural change. The problems arising from this process are tackled in very different ways. In the public discussion the different approaches of Japan on the one side and of Western European countries on the other have received consider able attention. Structural change in its economic, social and political aspects has been the subject of the 8th German-Japanese Seminar on Economics and Social Sciences, held at Cologne from the 24th to the 27th of September, 1984. The tradition of German-Japanese Seminars on Economics and Social Sciences goes back to 1966, when the first meeting was held at Tokyo. Among the first participants were Dr. Hiromi Arizawa, Dr. Kazuo Okochi, both professors at the University of Tokyo, and Dr. Karl Hax, professor at Frankfurt University. The objective of all seminars, which have been held since, has been the analysis of eco nomic and social problems of immediate interest in both countries. The records of former seminars, which have been published partly in Japanese, partly in German throw light upon the shift of empha sis toward new problems which took place during aperiod of 18 years. 204 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The goal of this book is to create awareness for a change in mind-set that we will all have to face and go through. The necessity for this new mind set is being driven by the situation that a completely new business world, a new reality, is being created at the point where the phenomenon commonly referred to as the 'new economy' converges with the well-known old economy. During the very late 1990s, this new reality was being driven by an almost incredible increase in yields in the financial markets, where conventional but value-driven and stable stocks such as Philip Morris, General Electric, or Bayer, did not attract as many investors as before - if we can call some of them investors at all. Companies in the high-tech or the new market segments are all part of the new economy. This new economy has created new business ideas, business models, and a new reality, in which chief executive officers (CEOs) were in the mid twenties and had basically no clue as to what real business is and how much a dollar counts. Now, as this convergence is happening, the painful reality and the business rules of the old economy get us back down to earth. The CEOs become more senior, business plans are validated more carefully, and just having the famous '. com' in your company name does not get you any further or lead you to any of required money. 252 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In 1984, the University of Bonn (FRG) and the International Institute for Applied System Analysis (IIASA) in Laxenburg (Austria), created a joint research group to analyze the relationship between economic growth and structural change. The research team was to examine the commodity composition as well as the size and direction of commodity and credit flows among countries and regions. Krelle (1988) reports on the results of this 'Bonn-IIASA' research project. At the same time, an informal IIASA Working Group was initiated to deal with prob lems of the statistical analysis of economic data in the context of structural change: What tools do we have to identify nonconstancy of model parameters What type of models are particularly applicable to nonconstant structure How is forecasting affected by the presence of nonconstant structure What problems should be anticipated in applying these tools and models Some 50 experts, mainly statisticians or econometricians from about 15 countries, came together in Lodz, Poland (May 1985); Berlin, GDR (June 1986); and Sulejov, Poland (September 1986) to present and discuss their findings. This volume contains a selected set of those conference contributions as well as several specially invited chapters. 512 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book develops a new theory of the modern economy. Conventional economic theory is (still) based on an essentially static notion of equilibrium. In contrast, this book offers an analysis of the economic process based on a truly dynamic approach. It understands modern economic activity as manifesting itself in a growth spiral. There are two main drivers of the dynamics of this spiral: steady money creation in the banking system, on the one hand; and the continuous inflow of energy and raw materials through the exploitation of natural resources, on the other. Both driving forces are generally neglected by the conventional theory. Understanding their role is absolutely essential for preventing our economy from being more and more exposed to financial and ecological crises. This book offers important insights about the functioning of the modern economy and addresses the specialist as well as the interested lay reader. 180 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Almost every company wants to grow - at least officially. Shareholders are demanding further growth and no management team would deny that the growth of their company is one of the top issues they are working on every single day. However, there are barriers to growth, and these are not only external barriers. Most often it is not the economy, not the market and not the customer who just 'hasn't got it.' The main barriers can be discovered inside every company, because growth always comes from within. If the organization is not ready to grow, initiatives to increase market share, to enter new markets, and/or to increase profitability are destined to fail. This book systematically addresses the main internal barriers to growth and provides practical guidance not only for discovering these barriers, but to systematically overcoming them. 200 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -China is dramatically catching up and is rapidly becoming a leading technological innovator on the global scale. The number of Chinese firms with global ambitions is growing fast, more and more technological innovation is coming from China, and the number of patents in China is also growing steadily. The negative side of this development is the still insufficient protection of intellectual property in China. The phenomenon of counterfeits originating from China has increased constantly over the past two decades. Moreover, within the past ten years the scale of intellectual property theft has risen exponentially in terms of its sophistication, volume, the range of goods, and the countries affected. This book addresses managers dealing with innovation in China, and offers concrete advice on how Western firms can benefit from these innovations. Among others, it provides examples and checklists to help decision-makers active in China. 140 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -,The papers in this collection, written by a cross-regional group of experts, provide insights into the causes of declining levels of citizen participation and other distinct forms of civic activism in Europe and explore a range of factors contributing to apathy and eventually disengagement from vital political processes and institutions. At the same time, this volume examines informal or unconventional types of civic engagement and political participation corresponding to the rapid advances in culture, technology and social networking. The volume is divided into three interrelated parts: Part I consists of critical essays in the form of theoretical approaches to analysing weakening political participation and citizen estrangement; Part II is dedicated to an exploration of the role and deployment of technologically advanced media, such as the internet, as determinants of changing patterns of political participationist behaviour. Finally, Part III presents findings of empirical research on the issue of political participation. Combining theoretical and empirical perspectives, the book contributes towards a better understanding of the disquieting trend of voter apathy and disenchantment with politics in the context of the ongoing process of European integration, and offers a variety of analytical tools for decoding both the emergence of alternative conceptualizations of citizenship and other forms of meaningful civic and political engagement. 304 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The renowned theoretical physicist Victor F. Weisskopf rightly pointed out that a real understanding of natural phenomena implies a clear distinction between the essential and the peripheral. Only when we reach such an understanding - that is to say when we are able to separate the relevant from the irrelevant, will the phenomena no longer appear complex, but intelectually transparent. This statement, which is generally valid, reflects the very essence ofmodelling in the quantum theory of matter, on the molecular level in particular. Indeed, without theoretical models one would be swamped by too many details embodied in intricate accurate molecular wavefunctions. Further, physically justified simplificqtions enable studies of the otherwise intractable systems and/or phenomena. Finally, a lack of appropriate models would leave myriads of raw experimental data totally unrelated and incomprehensible. The present series ofbooks dwells on the most important models of chemical bonding and on the variety of its manifestations. In this volume the electronic structure and properties of molecules are considered in depth. Particular attention is focused on the nature of intramolecular interactions which in turn are revealed by various types ofmolecular spectroscopy. Emphasis is put on the conceptual and interpretive aspects of the theory in line with the general philosophy adopted in the series. 656 pp. Englisch.…
