Neuware -Ordinary differential equations play a central role in science and have been extended to evolution equations in Banach spaces. For many applications, however, it is difficult to specify a suitable normed vector space. Shapes without a priori restrictions, for example, do not have an obvious linear structure.This book generalizes ordinary differential equations beyond the borders of vector spaces with a focus on the well-posed Cauchy problem in finite time intervals.Here are some of the examples: Feedback evolutions of compact subsets of the Euclidean space Birth-and-growth processes of random sets (not necessarily convex) Semilinear evolution equations Nonlocal parabolic differential equations Nonlinear transport equations for Radon measures A structured population model Stochastic differential equations with nonlocal sample dependence and how they can be coupled in systems immediately - due to the joint framework of Mutational Analysis. Finally, the book offers new tools for modelling.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 532 pp. Englisch.

Neuware -Most well known structures in planetary atmospheres and the Earth's oceans are jets or fronts interacting with vortices on a wide range of scales. The transition from one state to another, such as in unbalanced or adjustment flows, involves the generation of waves as well as the interaction of coherent structures with these waves.This book presents a fluid mechanics perspective to the dynamics of fronts and vortices and their interaction with waves in geophysical flows. It provides a basic physical background for modeling coherent structures in a geophysical context, and it gives essential information on advanced topics such as spontaneous wave emission and wavemomentum transfer in geophysical flows.Based on a set of lectures by leading specialists, this text is targeted at graduate students, researchers and engineers in geophysics and environmental fluid mechanics.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 204 pp. Englisch.

Neuware -Linear elliptic equations arise in several models describing various phenomena in the applied sciences, the most famous being the second order stationary heat eq- tion or,equivalently,the membraneequation. Forthis intensivelywell-studiedlinear problem there are two main lines of results. The rst line consists of existence and regularity results. Usually the solution exists and ¿gains two orders of differen- ation¿ with respect to the source term. The second line contains comparison type results, namely the property that a positive source term implies that the solution is positive under suitable side constraints such as homogeneous Dirichlet bou- ary conditions. This property is often also called positivity preserving or, simply, maximum principle. These kinds of results hold for general second order elliptic problems, see the books by Gilbarg-Trudinger [198] and Protter-Weinberger [347]. For linear higher order elliptic problems the existence and regularitytype results - main, as one may say, in their full generality whereas comparison type results may fail. Here and in the sequel ¿higher order¿ means order at least four. Most interesting models, however, are nonlinear. By now, the theory of second order elliptic problems is quite well developed for semilinear, quasilinear and even for some fully nonlinear problems. If one looks closely at the tools being used in the proofs, then one nds that many results bene t in some way from the positivity preserving property. Techniques based on Harnack¿s inequality, De Giorgi-Nash- Moser¿s iteration, viscosity solutions etc.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 448 pp. Englisch.

Neuware -Deeply rooted in fundamental research in Mathematics and Computer Science, Cellular Automata (CA) are recognized as an intuitive modeling paradigm for Complex Systems. Already very basic CA, with extremely simple micro dynamics such as the Game of Life, show an almost endless display of complex emergent behavior. Conversely, CA can also be designed to produce a desired emergent behavior, using either theoretical methodologies or evolutionary techniques. Meanwhile, beyond the original realm of applications - Physics, Computer Science, and Mathematics ¿ CA have also become work horses in very different disciplines such as epidemiology, immunology, sociology, and finance.In this context of fast and impressive progress, spurred further by the enormous attraction these topics have on students, this book emerges as a welcome overview of the field for its practitioners, as well as a good starting point for detailed study on the graduate and post-graduate level.The book contains three parts, two major parts on theory and applications, and a smaller part on software. The theory part contains fundamental chapters on how to design and/or apply CA for many different areas. In the applications part a number of representative examples of really using CA in a broad range of disciplines is provided - this part will give the reader a good idea of the real strength of this kind of modeling as well as the incentive to apply CA in their own field of study. Finally, we included a smaller section on software, to highlight the important work that has been done to create high quality problem solving environments that allow to quickly and relatively easily implement a CA model and run simulations, both on the desktop and if needed, on High Performance Computing infrastructures.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 408 pp. Englisch.

Earlier dc motors were the only drives that were used in industries requiring - eration over a wide range of speed with step less variation, or requiring fine ac- racy of speed control. Such drives are known as high performance drives. AC - tors because of being highly coupled non-linear devices can not provide fast dynamic response with normal controls. However, recently, because of ready availability of power electronic devices, and digital signal processors ac motors are beginning to be used for high performance drives. Field oriented control or vector control has made a fundamental change with regard to dynamic perfo- ance of ac machines. Vector control makes it possible to control induction or s- chronous motor in a manner similar to control scheme used for the separately - cited dc motor. Recent advances in artificial intelligence techniques have also contributed in the improvement in performance of electric drives. This book presents a comprehensive view of high performance ac drives. It may be considered as both a text book for graduate students and as an up-to-date monograph. It may also be used by R & D professionals involved in the impro- ment of performance of drives in the industries. The book will also be beneficial to the researchers pursuing work on sensorless and direct torque control of electric drives as up-to date references in these topics are provided.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Neuware -Through the past 20 years, the framework of Linear Parameter-Varying (LPV) systems has become a promising system theoretical approach to handle the control of mildly nonlinear and especially position dependent systems which are common in mechatronic applications and in the process industry. The birth of this system class was initiated by the need of engineers to achieve better performance for nonlinear and time-varying dynamics, c- mon in many industrial applications, than what the classical framework of Linear Time-Invariant (LTI) control can provide. However, it was also a p- mary goal to preserve simplicity and ¿re-use¿ the powerful LTI results by extending them to the LPV case. The progress continued according to this philosophy and LPV control has become a well established eld with many promising applications. Unfortunately, modeling of LPV systems, especially based on measured data (which is called system identi cation) has seen a limited development sincethebirthoftheframework.Currentlythisbottleneck oftheLPVfra- work is halting the transfer of the LPV theory into industrial use. Without good models that ful ll the expectations of the users and without the und- standing how these models correspond to the dynamics of the application, it is di cult to design high performance LPV control solutions. This book aims to bridge the gap between modeling and control by investigating the fundamental questions of LPV modeling and identi cation. It explores the missing details of the LPV system theory that have hindered the formu- tion of a well established identi cation framework.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 348 pp. Englisch.

Neuware -Since the concept of allelopathy was introduced almost 100 years ago, research has led to an understanding that plants are involved in complex communicative interactions. They use a battery of different signals that convey plant-relevant information within plant individuals as well as between plants of the same species or different species. The 13 chapters of this volume discuss all these topics from an ecological perspective. Communication between plants allows them to share physiological and ecological information relevant for their survival and tness. It is obvious that in these very early days of ecological plant communication research we are illuminating only the ¿tip of iceberg¿ of the communicative nature of higher plants. Nevertheless, knowledge on the identity and informative value of volatiles used by plants for communication is increasing with breath-taking speed. Among the most spectacular examples are sit- tions where plant emitters warn neighbours about a danger, increasing their innate immunity, or when herbivore-attacked plants attract the enemies of the herbivores (¿cry for help¿ and ¿plant bodyguards¿ concepts). It is becoming obvious that plants use not only volatile signals but also diverse water soluble molecules, in the case of plant roots, to safeguard their evolutionary success and accomplish self/non-self kin rec- nition. Importantly, as with all the examples of biocommunication, irrespective of whether signals and signs are transmitted via physical or chemical pathways, plant communication is a rule-governed and sign-mediated process.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 260 pp. Englisch.

Fau- less function of the valves is a prerequisite for unidir- tional forward movement of the blood, and such function is necessary to support the ef orts of the cardiac atria and ventricles. Healthy heart valves function gracefully and of er mechanical durability. Bioengineers have to marvel at the biomechanical evolution of these perfectly placed valves. Heart valves can be involved in pathological processes, however, and only then do we realize just how indispensable they really are. At one time, serious valve disorders used to be a matter of life and death for patients. Only in recent decades have surgeons been able to reverse the ominous course of heart valve disease and of er patients a quality of life and life span comparable to that of healthy persons. T e story of this ef ort began approximately 100 years ago, and today heart valve surgery is a substantial subspecialty of cardiac surgery, with accumulated experience in indications, procedures, risks, and outcomes. T e aim of this book is to present a richly illustrated compendium of the present knowledge related to heart valve surgery, based on the clinical expertise of the authors as well as the newest treatment modalities. T e authors thank Dr. Alireeza Matloobi from the Mayo Clinic for his help in preparating the book.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 416 pp. Englisch.

Neuware -Requirements engineering has since long acknowledged the importance of the notion that system requirements are stakeholder goals¿rather than system functions¿and ought to be elicited, modeled and analyzed accordingly.In this book, Nurcan and her co-editors collected twenty contributions from leading researchers in requirements engineering with the intention to comprehensively present an overview of the different perspectives that exist today, in 2010, on the concept of intention in the information systems community. These original papers honor Colette Rolland for her contributions to this field, as she was probably the first to emphasize that ¿intention¿ has to be considered as a first-class concept in information systems engineering. Written by long-term collaborators (and most often friends) of Colette Rolland, this volume covers topics like goal-oriented requirements engineering, model-driven development, method engineering, and enterprise modeling.As such, it is a tour d¿horizon of Colette Rolland¿s lifework, and is presented to her on the occasion of her retirement at CaISE 2010 in Hammamet, the conference she once cofounded and which she helped to grow and prosper for more than 20 years.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 408 pp. Englisch.

Neuware -Die zunehmende Ressourcenknappheit im Gesundheitswesen bei raschem medizinischem, technischem und wissenschaftlichem Fortschritt erfordert ein ökonomisches Denken. Dabei darf die Qualität der Patientenversorgung nicht unter wirtschaftlichen Gesichtspunkten leiden, sie muss sich stets auf dem aktuellen Wissens- und Versorgungsstand befinden. Diesem Spannungsfeld unterliegt auch die Notfallmedizin, die sich längst von der Ersten Hilfe in eine spezifische, präklinische Intensivtherapie gewandelt hat. Um die Effizienz der gesamten Prozesskette der Rettungseinsätze zu optimieren, setzt die Notfallversorgung große Hoffnungen in den Einsatz moderner technologischer Entwicklungen. Von einer telematischen Vernetzung des präklinischen Bereichs verspricht sich die Notfallmedizin die Verbesserung der Versorgungsqualität bei gleichzeitiger Senkung der betrieblichen und volkswirtschaftlichen Kosten. Der vorliegende Band zeigt die rechtlichen Vorgaben und Anforderungen an die Implementierung eines telemedizinischen Rettungsassistenzsystems auf. Medizinrechtliche, haftungs- und datenschutzrechtliche Fragestellungen werden dargestellt, darüber hinaus erfolgt eine vergleichende Betrachtung ausgewählter europäischer Rettungsdienstsysteme.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 200 pp. Deutsch.

Neuware -Die nachhaltige Lösung von Problemen der Energieversorgung gehört zu den zentralen Herausforderungen moderner Zivilisationen. Aus ökonomischer Sicht greifen alle Antworten zu kurz, die nicht explizit das interessengeleitete Handeln der wesentlichen Akteure berücksichtigen. Deshalb behandelt dieses Buch die nachfrage- und angebotsseitigen Gesetzmäßigkeiten der verschiedenen Energiemärkte, und zwar unter Rückgriff auf industrie- und institutionenökonomische Theoriebausteine. Die technisch-naturwissenschaftlichen Bedingungen von Gewinnung, Wandlung, Transport, Verteilung und Nutzung von Energieträgern werden dabei stets berücksichtigt. Ein wichtiges Thema für die Praktiker sind die von der Liberalisierung der leitungsgebundenen Energiemärkte ausgehenden Impulse. Wo immer möglich werden die theoretisch hergeleiteten Voraussagen durch die Konfrontation mit statistischer Evidenz auf ihre Praxisrelevanz geprüft.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 396 pp. Deutsch.
