Buch. Condizione: Neu. Neuware -This classic reference on musical acoustics and performance practice begins with a brief introduction to the fundamentals of acoustics and the generation of musical sounds. It then discusses the particulars of the sounds made by all the standard instruments in a modern orchestra as well as the human voice, the way in which the sounds made by these instruments are dispersed and how the room into which they are projected affects the sounds.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 464 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware - Enclosed ecosystem experiments have gained in popularity as research tools in ecological science, particularly in the study of coastal aquatic environments. These systems provide scientists with a degree of experimental control that is not achievable through field experiments. Yet to date, techniques for systematically extrapolating results from small-scale experimental ecosystems to larger, deeper, more open, more biologically diverse, and more heterogeneous ecosystems in nature have not been well developed. Likewise, researchers have lacked methods for comparing and extrapolating information among natural ecosystems that differ in scale.Enclosed Experimental Ecosystems and Scale: Tools for Understanding and Managing Coastal Ecosystems provides scientists, managers, and policy makers with an introduction to what has been termed the 'problem of scale', and presents information that will allow for improved design and interpretation of enclosed experimental aquatic ecosystems. The book integrates the results of a 10-year research project involving a multi-disciplinary team of scientists and students to explore scale-related questions in a variety of coastal habitats. Anticipating use as a reference, the book has been designed so that individual sections and individual pages can function as stand alone units.

Taschenbuch. Condizione: Neu. Neuware -Abstract: An outline of the structure of the book is presented, making the argument that the language we use for everyday mathematical ideas presents us with valuable evidence and insights into the nature of mathematics. Keywords: mathematical discourse, nature of mathematics I begin the book by looking at the way people speaking different languages talk about mathematical ideas in their everyday conversation. I end up questioning some common beliefs about mathematics, its history, and its pedagogy. The way we (English speakers) use numbers, the way we give directions, the way we express relationships, are all so commonplace that it is hard to imagine any other way of expressing these ideas. We take for granted the structures of the following sentences: There are four people in the room. The book costs forty-five dollars. Two and three are five. Turn left. Go straight on. The sun rises in the east. A dog is a mammal. He is not my father. I will either go shopping or read my book this afternoon.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

DOI: 10. 1007/s11214-008-9353-0 Springer Science+Business Media B. V. 2008 Keywords Aeronomy The term 'aeronomy' has been used widely for many decades, but its origin has mostly been lost over the years. It was introduced by Sydney Chapman in a Letter to the Editor, entitled 'Some Thoughts on Nomenclature', in Nature in 1946 (Chapman 1946). In that letter he suggested that aeronomy should replace meteorology, writing that the word 'meteor is now irrelevant and misleading'. This proposal was apparently not received with much support so in a short note in Weather in 1953 Chapman (1953)wrote: 'If, despite its obvious convenience of brevity in itself and its derivatives, it does not commend itself to aeronomers, I think there is a case for modifying my proposal so that instead of the word being used to signify the study of the atmosphere in general, it should be adopted with the restricted sense of the science of the upper atmosphere, for which there is no convenient short word. ' In a chapter, he wrote in a 1960 book (Chapman 1960), he give his nal and de nitive de nition, by stating that 'Aeronomy is the science of the upper region of the atmosphere, where dissociation and ionization are important'. The Workshop on 'Comparative Aeronomy' was held at ISSI during the week of June 25-29, 2007. 464 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of this monograph is to describe the main concepts and recent - vances in multiscale nite element methods. This monograph is intended for thebroaderaudienceincludingengineers,appliedscientists,andforthosewho are interested in multiscale simulations. The book is intended for graduate students in applied mathematics and those interested in multiscale compu- tions. It combines a practical introduction, numerical results, and analysis of multiscale nite element methods. Due to the page limitation, the material has been condensed. Each chapter of the book starts with an introduction and description of the proposed methods and motivating examples. Some new techniques are introduced using formal arguments that are justi ed later in the last chapter. Numerical examples demonstrating the signi cance of the proposed methods are presented in each chapter following the description of the methods. In the last chapter, we analyze a few representative cases with the objective of demonstrating the main error sources and the convergence of the proposed methods. A brief outline of the book is as follows. The rst chapter gives a general introductiontomultiscalemethodsandanoutlineofeachchapter.Thesecond chapter discusses the main idea of the multiscale nite element method and its extensions. This chapter also gives an overview of multiscale nite element methods and other related methods. The third chapter discusses the ext- sion of multiscale nite element methods to nonlinear problems. The fourth chapter focuses on multiscale methods that use limited global information. 248 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The area of eastern Africa, which includes Tanzania and Kenya, is known for its savannas, wildlife and tribal peoples. Alongside these iconic images lie concerns about environmental degradation, declining wildlife populations, and about worsening poverty of pastoral peoples. East Africa presents in microcosm the paradox so widely seen across sub Saharan Africa, where the world¿s poorest and most vulnerable populations live alongside some of the world¿s most outstanding biodiversity resources.Over the last decade or so, community conservation has emerged as a way out of poverty and environmental problems for these rural populations, focusing on the sustainable use of wildlife to generate income that could underpin equally sustainable development. Given the enduring interest in East African wildlife, and the very large tourist income it generates, these communities and ecosystems seem a natural case for green development based on community conservation.This volume is focused on the livelihoods of the Maasai in two different countries - Kenya and Tanzania. This cross-border comparative analysis looks at what people do, why they choose to do it, with what success and with what implications for wildlife. The comparative approach makes it possible to unpack the interaction of conservation and development, to identify the main drivers of livelihoods change and the main outcomes of wildlife conservation or other land use policies, while controlling for confounding factors in these semi-arid and perennially variable systems. This synthesis draws out lessons about the successes and failures of community conservation-based approach to development in Maasailand under different national political and economic contexts and different local social and historical particularities.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 436 pp. Englisch.

Buch. Condizione: Neu. Neuware -I feel very honoured to have been asked to write a brief foreword for this book on QRD-RLS Adaptive Filtering¿asubjectwhichhas been close to my heart for many years. The book is well written and very timely ¿ I look forward personally to seeing it in print. The editor is to be congratulated on assembling such a highly esteemed team of contributing authors able to span the broad range of topics and concepts which underpin this subject. In many respects, and for reasons well expounded by the authors, the LMS al- rithm has reigned supreme since its inception, as the algorithm of choice for prac- cal applications of adaptive ltering. However, as a result of the relentless advances in electronic technology, the demand for stable and ef cient RLS algorithms is growing rapidly ¿ not just because the higher computational load is no longer such a serious barrier, but also because the technological pull has grown much stronger in the modern commercial world of 3G mobile communications, cognitive radio, high speed imagery, and so on.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book covers a significant number of R&D projects, performed mostly after 2000, devoted to the understanding and prevention of performance degradation processes in polymer electrolyte fuel cells (PEFCs). The extent and severity of performance degradation processes in PEFCs were recognized rather gradually. Indeed, the recognition overlapped with a significant number of industrial dem- strations of fuel cell powered vehicles, which would suggest a degree of technology maturity beyond the resaolution of fundamental failure mechanisms. An intriguing question, therefore, is why has there been this apparent delay in addressing fun- mental performance stability requirements. The apparent answer is that testing of the power system under fully realistic operation conditions was one prerequisite for revealing the nature and extent of some key modes of PEFC stack failure. Such modes of failure were not exposed to a similar degree, or not at all, in earlier tests of PEFC stacks which were not performed under fully relevant conditions, parti- larly such tests which did not include multiple on¿off and/or high power¿low power cycles typical for transportation and mobile power applications of PEFCs. Long-term testing of PEFCs reported in the early 1990s by both Los Alamos National Laboratory and Ballard Power was performed under conditions of c- stant cell voltage, typically near the maximum power point of the PEFC.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 528 pp. Englisch.

Buch. Condizione: Neu. Neuware -The Solar-B satellite was launched in the morning of 23 September 2006 (06:36 Japan time) by the Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS/JAXA), and was renamed to Hinode (¿sunrise¿ in Japanese). Hinode carries three - struments; the X-ray telescope (XRT), the EUV imaging spectrometer (EIS), and the solar optical telescope (SOT). These instruments were developed by ISAS/JAXA in cooperation with the National Astronomical Observatory of Japan as domestic partner, and NASA and the Science and Technology Facilities Council (UK) as international partners. ESA and N- wegian Space Center have been providing a downlink station. All the data taken with Hinode are open to everyone since May 2007. This volume combines the rst set of instrumental papers of the Hinode mission (the mission overview, EIS, XRT, and the database system) published in volume 243, Number 1 (June 2007), and the second set of papers (four papers on SOT and one paper on XRT) published in Volume 249, Number 2 (June 2008). Another SOT paper cited as Tarbell et al. (2008) in these papers will appear later in Solar Physics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Buch. Condizione: Neu. Neuware -Quasi¿Monte Carlo methods have become an increasingly popular alternative to Monte Carlo methods over the last two decades. Their successful implementation on practical problems, especially in finance, has motivated the development of several new research areas within this field to which practitioners and researchers from various disciplines currently contribute.This book presents essential tools for using quasi¿Monte Carlo sampling in practice. The first part of the book focuses on issues related to Monte Carlo methods¿uniform and non-uniform random number generation, variance reduction techniques¿but the material is presented to prepare the readers for the next step, which is to replace the random sampling inherent to Monte Carlo by quasi¿random sampling. The second part of the book deals with this next step. Several aspects of quasi-Monte Carlo methods are covered, including constructions, randomizations, the use of ANOVA decompositions, and the concept of effective dimension. The third part of the book is devoted to applications in finance and more advanced statistical tools like Markov chain Monte Carlo and sequential Monte Carlo, with a discussion of their quasi¿Monte Carlo counterpart.The prerequisites for reading this book are a basic knowledge of statistics and enough mathematical maturity to follow through the various techniques used throughout the book. This text is aimed at graduate students in statistics, management science, operations research, engineering, and applied mathematics. It should also be useful to practitioners who want to learn more about Monte Carlo and quasi¿Monte Carlo methods and researchers interested in an up-to-date guide to these methods.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 392 pp. Englisch.

Buch. Condizione: Neu. Neuware -Classical probability theory provides information about random walks after a fixed number of steps. For applications, however, it is more natural to consider random walks evaluated after a random number of steps. Examples are sequential analysis, queueing theory, storage and inventory theory, insurance risk theory, reliability theory, and the theory of counters. Stopped Random Walks: Limit Theorems and Applications shows how this theory can be used to prove limit theorems for renewal counting processes, first passage time processes, and certain two-dimensional random walks, and to how these results are useful in various applications.This second edition offers updated content and an outlook on further results, extensions and generalizations. A new chapter examines nonlinear renewal processes in order to present the analagous theory for perturbed random walks, modeled as a random walk plus ¿noise¿.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch.

Buch. Condizione: Neu. Neuware - Making a robot that looks and behaves like a human being has been the subject of many popular science fiction movies and books. Although the development of such a robot facesmanychallenges,themakingofavirtualhumanhaslongbeenpotent iallypossible. With recent advances in various key technologies related to hardware and software, the making of humanlike robots is increasingly becoming an engineering reality. Development of the required hardware that can perform humanlike functions in a lifelike manner has benefitted greatly from development in such technologies as biologically inspired materials, artificial intelligence, artificial vision, and many others. Producing a humanlike robot that makes body and facial expressions, communicates verbally using extensive vocabulary, and interprets speech with high accuracy is ext- mely complicated to engineer. Advances in voice recognition and speech synthesis are increasingly improving communication capabilities. In our daily life we encounter such innovations when we call the telephone operators of most companies today. As robotics technology continues to improve we are approaching the point where, on seeing such a robot, we will respond with ''Wow, this robot looks unbelievably real!'' just like the reaction to an artificial flower. The accelerating pace of advances in related fields suggests that the emergence of humanlike robots that become part of our daily life seems to be imminent. These robots are expected to raise ethical concerns and may also raise many complex questions related to their interaction with humans.

The ¿original¿ Global Helioseismology has reached a level of maturity that allows many internal prop- ties of the Sun to be probed with exquisite precision, although it currently faces a severe challenge to reconcile interior models with helioseismic inversions near the base of the c- vection zone in the age of the new solar chemical abundances. Asteroseismology suffers in comparisonbybeingrestrictedtoverylowsphericalharmonicdegree( ),butitmakesupfor this by providing many more subjects for study (including solar-like stars) and many cases of well-identi ed g modes. Where once we were restricted to stellar spectra in studying in- vidual stars, asteroseismology now provides a crucial tool with which we may explore their deep structure. Its natural synergy with planet-search programs also invigorates it. Local Helioseismology has seen the development of an exciting array of techniques and insights over the two decades since observations of surface oscillations in and around active regions gave the rst clues that something different was happening there, and it has been parti- larly important in mapping ows of various types in shallow subsurface layers.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 644 pp. Englisch.
