Taschenbuch. Zustand: Neu. Neuware -'Numerische Mathematik', aufgeteilt in zwei Bände, ist eine Einführung in die Numerische Mathematik anhand von Differentialgleichungsproblemen. Gegliedert nach elliptischen, parabolischen und hyperbolischen Differentialgleichungen wird zunächst jeweils die Diskretisierung solcher Probleme besprochen. Als Diskretisierungstechniken stehen Finite-Elemente-Methoden im Raum und (partitionierte) Runge-Kutta-Methoden in der Zeit im Vordergrund. Die diskretisierten Gleichungen dienen als Motivation zur Diskussion von Methoden für endlichdimensionale lineare und nichtlineare Gleichungen, die anschließend als eigenständige Themen behandelt werden. Auf diese Weise wird versucht, nicht nur ein einführendes sondern auch ein in sich abgeschlossenes Bild der Numerischen Mathematik, zumindest in einem zentralen Aufgabenbereich, zu vermitteln.Der zweite Band setzt mit der Diskussion parabolischer und hyperbolischer Anfangsrandwertprobleme fort. Die durch Semi-Diskretisierung im Raum entstehenden Anfangswertprobleme dienen als Einstieg und Motivation der anschließenden Behandlung allgemeiner Anfangswertprobleme gewöhnlicher Differentialgleichungen erster und zweiter Ordnung. Schließlich werden die für diese allgemeinen Problemstellungen erarbeiteten Erkenntnisse auf semi-diskretisierte parabolische und hyperbolische Probleme angewendet.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 168 pp. Deutsch.

Taschenbuch. Zustand: Neu. Neuware -Science fiction is the playground of the imagination. If you are interested in science or fascinated with the future then science fiction is where you explore new ideas and let your dreams and nightmares duke it out on the safety of the page or screen. But what if we could use science fiction to do more than that What if we could use science fiction based on science fact to not only imagine our future but develop new technologies and products What if we could use stories, movies and comics as a kind of tool to explore the real world implications and uses of future technologies today Science Fiction Prototyping is a practical guide to using fiction as a way to imagine our future in a whole new way. Filled with history, real world examples and conversations with experts like best selling science fiction author Cory Doctorow, senior editor at Dark Horse Comics Chris Warner and Hollywood science expert Sidney Perkowitz, Science Fiction Prototyping will give you the tools you need tobegin designing the future with science fiction.The future is Brian David Johnson¿s business. As a futurist at Intel Corporation, his charter is to develop an actionable vision for computing in 2021. His work is called ¿future casting¿¿using ethnographic field studies, technology research, trend data, and even science fiction to create a pragmatic vision of consumers and computing. Johnson has been pioneering development in artificial intelligence, robotics, and reinventing TV. He speaks and writes extensively about future technologies in articles and scientific papers as well as science fiction short stories and novels (Fake Plastic Love and Screen Future: The Future of Entertainment, Computing and the Devices We Love). He has directed two feature films and is an illustrator and commissioned painter.Table of Contents: Preface / Foreword / Epilogue / Dedication / Acknowledgments / 1. The Future Is in Your Hands / 2.

Taschenbuch. Zustand: Neu. Neuware -In the history of modern computation, large mechanical calculators preceded computers. A person would sit there punching keys according to a procedure and a number would eventually appear. Once calculators became fast enough, it became obvious that the critical path was the punching rather than the calculation itself. That is what made the stored program concept vital to further progress. Once the instructions were stored in the machine, the entire computation could run at the speed of the machine. This book shows how to do the same thing for DNA computing. Rather than asking a robot or a person to pour in specific strands at different times in order to cause a DNA computation to occur (by analogy to a person punching numbers and operations into a mechanical calculator), the DNA instructions are stored within the solution and guide the entire computation. We show how to store straight line programs, conditionals, loops, and a rudimentary form of subroutines.To achieve this goal, the book proposes a complete language for describing the intrinsic topology of DNA complexes and nanomachines, along with the dynamics of such a system. We then describe dynamic behavior using a set of basic transitions, which operate on a small neighborhood within a complex in a well-defined way. These transitions can be formalized as purely syntactical functions of the string representations.Building on that foundation, the book proposes a novel machine motif which constitutes an instruction stack, allowing for the clocked release of an arbitrary sequence of DNA instruction or data strands. The clock mechanism is built of special strands of DNA called ''tick'' and ''tock.'' Each time a ''tick'' and ''tock'' enter a DNA solution, a strand is released from an instruction stack (by analogy to the way in which as a clock cycle in an electronic computer causes a new instruction to enter a processing unit). As long as there remain strands on the stack, the next cycle will release a new instruction strand. Regardless of the actual strand or component to be released at any particular clock step, the ''tick'' and ''tock'' fuel strands remain the same, thus shifting the burden of work away from the end user of a machine and easing operation. Pre-loaded stacks enable the concept of a stored program to be realized as a physical DNA mechanism.A conceptual example is given of such a stack operating a walker device. The stack allows for a user to operate such a clocked walker by means of simple repetition of adding two fuel types, in contrast to the previous mechanism of adding a unique fuel -- at least 12 different types of strands -- for each step of the mechanism.We demonstrate by a series of experiments conducted in Ned Seeman's lab that it is possible to ''initialize'' a clocked stored program DNA machine. We end the book with a discussion of the design features of a programming language for clocked DNA programming. There is a lot left to do.Table of Contents:Introduction / Notation / A Topological Description of DNA Computing / Machines and Motifs / Experiment: Storing Clocked Programs in DNA / A Clocked DNA Programming LanguageSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 76 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Ist im Einzelfall eine komplexe Bewertung für die Gesetzeskonkretisierung erforderlich, insbesondere von außerrechtlichen Standards, so wird mit jener Bewertung grundsätzlich eine besonders fachqualifizierte Stelle betraut. Im Bereich der medizinischen Forschung sind dies jene Kollegialorgane, die mit dem Begriff ¿Ethik-Kommissionen¿ unscharf in Bezug genommen werden. Ihnen obliegt es, den vom Gesetzgeber nur teilweise vorgezeichneten Spagat zwischen Innovation und Rechtsgüterschutz im Einzelfall zu bewerten oder zu entscheiden. Diese Risikoverwaltungstätigkeit im Geflecht von zahlreichen Vorschriften, außerrechtlichen Standards und ethischen Grundsätzen geht einher mit der Gefahr von Fehlentscheidungen. Ebenso wie in den USA wird die Haftung für Fehlentscheidungen von Ethik-Kommissionen hierzulandekontrovers diskutiert. Zumindest seit der 12. AMG-Novelle ist die Haftung für Ethik-Kommissionen kein theoretisches Problem der Wissenschaft mehr. Die vorliegende Untersuchung widmet sich in erster Linie der Haftung für Ethik-Kommissionen in der medizinischen Forschung am Menschen und nimmt dabei die Arzneimittelprüfung sowie die Risikoverwaltungstätigkeit der Ethik-Kommissionen besonders in den Blick. Neben der historischen Entwicklung und Darstellung der Haftungskonstellationen in den anderen Forschungsbereichen zeigt die Arbeit aber auch Grundlagen der Ethik-Kommissionstätigkeit, insbesondere im Zusammenhang mit der verwaltungsrechtlichen Einbettung von Ethik-Kommissionen, sowie Standards der medizinischen Forschung auf, ohne deren Beschäftigung eine praxisnahe Herausarbeitung der Haftungsrisiken nicht möglich gewesen wäre.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 756 pp. Deutsch.

Buch. Zustand: Neu. Neuware -To understand why we humans are as we are, it is necessary to look at the essential building blocks thatcomprise our nature. The foundations of this structureareour evolutionary origins as primates and our social roots. Upon these rest features such as ouremotions, language and aesthetic preferences, with ourself-perceptions, self-deceptions and thirst for knowledge right at the top.The unifying force holding these blocks together is evolutionary theory. Evolution provides a deeper understanding ofhuman nature and, in particular,of thecommon roots of these different perspectives.To build a reliable and coherent model of man, leading authors from fields as diverse as primatology, anthropology, neurobiology and philosophy have joined forces to present essays each describing their own expert perspective. Together they provide a convincing and complete picture of our own humannature.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 176 pp. Englisch.

Buch. Zustand: Neu. Neuware -This book introduces a new approach in designing E-Librarian Services. Such a system is able to retrieve multimedia resources from a digital library in a more efficient way than by browsing through an index, or by using a simple keyword search. It combines recent advances in multimedia information retrieval with aspects of human-machine interfaces. The user can enter his question in natural language. The premise is that more pertinent results would be retrieved if the search engine understood the sense of the user's query. The returned results are then logical consequences of an inference rather than of keyword matchings. An E-Librarian Service simulates a human librarian. Hence, it does not return the answer to the user's question, but it retrieves the most pertinent document(s), in which the user finds the answer to his question. Also, an E-Librarian Service always proposes a solution to the user, even if the system concludes that there is no exhaustive answer. 228 pp. Englisch.

Buch. Zustand: Neu. Neuware -The development and application of bioactive nano-structured constructs for tissue regeneration is the focus of the research summarised in this thesis. Moreover, a particular focus is the rational use of supercritical carbon dioxide foaming and electrospinning technologies which can lead to innovative polymeric bioresorbable scaffolds made of hydrolysable (both commercial and ¿ad-hoc¿ synthesized) polyesters. Mainly, the author discusses the manipulation of polymer chemical structure and composition to tune scaffold physical properties, and optimization of scaffold 3D architecture by a smart use of both fabrication techniques. The multidisciplinary nature of this research is imperative in pursuing the challenge of tissue regeneration successfully. One of the strengths of this thesis is the integration of knowledge from chemistry, physics, engineering, materials science and biomedical science which has contributed to setting up new national and international collaborations, while strengthening existing ones.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 136 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Si ripercorre la storia della cosmologia moderna, dal XVIII secolo fino alle più recenti scoperte (l'opera è aggiornata fino alla fine 2010). La cosmologia fa uso di concetti complessi, che vengono spesso fraintesi, o che non vengono compresi del tutto, da chi non è specialista del campo. Lo scopo del volume è di trattare esaustivamente tali concetti, entrando nel dettaglio per far cogliere intuitivamente il loro significato autentico anche ai non addetti: a questo scopo, si fa uso di metafore calzanti, di analogie newtoniane, di trattazioni quantitative che richiedono solo le conoscenze di fisica e di matematica di uno studente di scuola media superiore. Vengono discusse le idee più importanti e controverse che sono attualmente al centro del dibattito cosmologico, come la materia oscura e l'energia oscura. Vengono sviluppati i concetti di base della Relatività Generale e del Modello Standard delle particelle elementari. 240 pp. Italienisch.

Taschenbuch. Zustand: Neu. Neuware -The quality of education is a term that is frequently used in public debates. Understood in the sense of education being ¿generally okay¿ , or rather, most frequently, as ¿not okay¿. Perhaps there is an overruling nostalgic view that formerly education was better than today. In scholarly discourse there are those who maintain that the quality of education is an illusive term, with varying interpretations in different settings and by different stakeholders.In this book the complexity of the concept of education quality is recognized, but a conceptual framework is presented that makes quality, despite its complexity, amenable to rational and empirical analysis. Productivity, equity, effectiveness, efficiency and responsiveness of education systems are seen as key facets of quality. A concrete set of indicators is presented that makes for the measurement of these quality facets. In the second part of the book the quality framework is applied to an analysis of the quality of education in the Netherlands. Common sense in the Netherlands is dominated by the view that the quality of education is a course for serious concern. Some recent quality reviews take the same pessimistic outlook. However, the current overview of indicators on the Dutch system, seen from an international perspective, presents a picture that is much more positive. Still there is always room for improvement, in the case of the Netherlands this should probably be sought in diminishing the selectivity of the system as a way to improve participation in higher education.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 160 pp. Englisch.

Buch. Zustand: Neu. Neuware -Especially in times of an economic boom following a crisis, companies have to deal with the phenomenon of the 'working capital trap,' which signifies a company's increasing need for financial liquidity in times of hindered access to debt capital, caused by the increasingly restrictive credit approval processes of financial institutions. As a consequence of cost savings, this situation is often reinforced by a low level of inventory.This book takes up the problem and shows ways of escaping the 'trap' by identifying and strengthening in-house financing potential. First, different operating ratios will be introduced. These refer to the amount of capital committed to the flow of goods and to the amount of in-house financing possible. Subsequently, methods for consolidating in-house financing that are affected by procurement processes will be presented from the company's and the supply chain's perspective.From a company's perspective, the methods for consolidating the amount of in-house financing over the following topics: The Management of Payment Terms, Inventory Management and Product Group and Supplier ManagementFrom the supply chain's perspective, the following methods for extending the possible amount of in-house financing will be discussed: Finance-Oriented Supply Chain Sourcing, Supply Chain-Oriented Supplier Financing, Collaborative Cash-to-Cash Management, Collaborative Cash Pooling and Netting, Supply Chain Financing Platforms.The conceptual models will be clarified using a practical example from the automobile industry. Finally, the 'Procurement Value Added' (PVA ) approach will be presented, a concept that measures the contribution of procurement to the company's success.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 104 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The book contains research results obtained by applying Bejan's Constructal Theory to the study and therefore the optimization of fins, focusing on T-shaped and Y-shaped ones. Heat transfer from finned surfaces is an example of combined heat transfer natural or forced convection on the external parts of the fin, and conducting along the fin. Fin's heat exchange is rather complex, because of variation of both temperature along the fin and convective heat transfer coefficient. Furthermore possible presence of more fins invested by the same fluid flow has to be considered.Classical fin theory tried to reduce the coupled heat transfer problem to a one-dimensional problem by defining an average temperature of the fin and writing equations using this parameter. However, it was shown that this approach cannot be used because of the effects of two-dimensional heat transfer, especially in the presence of short fins. CFD codes offer the possibility to consider bi-dimensional (and more generally, three-dimensional) effects and then a more real approach to the physic phenomena of finned surface's heat exchange.A commercial CFD code was used to analyse the case of heat exchange in presence of T-shaped fins, following an approach suggested by Bejan's Constructal Theory. The comparative results showed a significant agreement with previous research taken as a reference, and this result allows for the application of this approach to a wider range of systems. T-shaped optimized fin geometry is the starting point for further research.Starting from the optimal results (T-shape optimized fins), we show the trend of the assessment parameter (the dimensionless conductance) in function of the angle a between the two horizontal arms of the fin.

Buch. Zustand: Neu. Neuware -The classical mechanistic idea of nature that prevailed in science during the eighteenth and nineteenth centuries was an essentially mindless conception: the physically described aspects of nature were asserted to be completely determined by prior physically described aspects alone, with our conscious experiences entering only passively. During the twentieth century the classical concepts were found to be inadequate. In the new theory, quantum mechanics, our conscious experiences enter into the dynamics in specified ways not fixed by the physically described aspects alone. Consequences of this radical change in our understanding of the connection between mind and brain are described. This second edition contains two new chapters investigating the role of quantum phenomena in the problem of free will and in the placebo effect.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Now is a critical time in pediatric informatics. As information technologies¿electronic health records (EHRs), personal health records (PHRs), computerized physician order entry (CPOE)¿and standards (HL7) are developed to improve the quality of health care, it is imperative for policy makers and pediatricians to be aware of their impact on pediatric care and child health. Informed child advocates must be at the planning table as national and regional health information networks are developed to insure the unique health care needs of children are being met.Pediatric Informatics: Computer Applications in Child Health is a current digest of the important trends in pediatric informatics, written by leading experts in the field. This book explores how the management of biomedical data, information, and knowledge can optimize and advance child health. The contributors investigate the specific importance of pediatric informatics is derived from the biological, psychological, social and cultural needs that the distinguish children from other populations. These distinctions create complexities in the management of pediatric data and information that make children a vulnerable population and require the development of a new body of knowledge in pediatric informatics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 508 pp. Englisch.

Buch. Zustand: Neu. Neuware -A paradigm shift is taking place in computer science: one generation ago, we learned to abstract from hardware to software, now we are abstracting from software to serviceware implemented through service-oriented computing. Yet ensuring interoperability in open, heterogeneous, and dynamically changing environments, such as the Internet, remains a major challenge for actual machine-to-machine integration. Usually significant problems in aligning data, processes, and protocols appear as soon as a specific piece of functionality is used within a different application context.The Semantic Web Services (SWS) approach is about describing services with metadata on the basis of domain ontologies as a means to enable their automatic location, execution, combination, and use. Fensel and his coauthors provide a comprehensive overview of SWS in line with actual industrial practice. They introduce the main sociotechnological components that ground the SWS vision (like Web Science, Service Science, and service-oriented architectures) and several approaches that realize it, e.g. the Web Service Modeling Framework, OWL-S, and RESTful services. The real-world relevance is emphasized through a series of case studies from large-scale R&D projects and a business-oriented proposition from the SWS technology provider Seekda.Each chapter of the book is structured according to a predefined template, covering both theoretical and practical aspects, and including walk-through examples and hands-on exercises. Additional learning material is available on the book website swsbook.org. With its additional features, the book is ideally suited as the basis for courses or self-study in this field, and it may also serve as a reference for researchers looking for a state-of-the-art overview of formalisms, methods, tools, and applications related to SWS.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.
