Buch. Condizione: Neu. Neuware -Researchers into HIV/AIDS face a gamut of ethical as well as scientific challenges. By viewing the gathering of data as a reciprocal activity between researchers, participants, and their communities, the expert contributors to Case Studies in Ethics and HIV Research bring these challenges to the fore. Studies from the United States and abroad depict the ongoing balance of risks and benefits while analyzing issues that range from confidentiality and informed consent to conducting studies with minority and other marginalized populations, from dealing with government and other funding agencies to ownership of findings. The book's 25 collaborators offer readers new templates for devising and conducting studies that are valid, meaningful, and morally sound, with critical implications for all research involving human subjects.

Taschenbuch. Condizione: Neu. Neuware -In wavelet analysis, irregular wavelet frames have recently come to the forefront of current research due to questions concerning the robustness and stability of wavelet algorithms. A major difficulty in the study of these systems is the highly sensitive interplay between geometric properties of a sequence of time-scale indices and frame properties of the associated wavelet systems.This volume provides the first thorough and comprehensive treatment of irregular wavelet frames by introducing and employing a new notion of affine density as a highly effective tool for examining the geometry of sequences of time-scale indices. Many of the results are new and published for the first time. Topics include: qualitative and quantitative density conditions for existence of irregular wavelet frames, non-existence of irregular co-affine frames, the Nyquist phenomenon for wavelet systems, and approximation properties of irregular wavelet frames.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 156 pp. Englisch.

Buch. Condizione: Neu. Neuware -These historical narratives of scientific behavior reveal the often irrational way scientists arrive at and assess their theories. There are stories of Einstein¿s stubbornness leading him to reject a correct interpretation of an experiment and miss an important deduction from his own theory, and Newton missing the important deduction from one of his most celebrated discoveries. Copernicus and Galileo are found suppressing information. A theme running throughout the book is the notion that what is obvious today was not so in the past. Scientists seen in their historical context shatter myths and show them to be less modern than we often like to think of them.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -RenderMan has long been associated with top-end film production and is an essential tool for creating many of the effects and images in recent animated films (such as Monsters, Inc., Finding Nemo and The Incredibles). RenderMan is widely available and, with the demand for higher quality images, is now used by computer-based artists at all levels of the graphics industry.Intended to provide a straightforward and easy introduction to the basic techniques involved, this book provides an excellent grounding, enabling readers to confidently move to more advanced texts. This second edition includes a new chapter on global illumination, and, with plenty of illustrations and hands-on examples, Ian Stephenson: gives an overview of RenderMan, explains how scenes are described, illustrates (among other things) how to create surfaces; colour; lighting; shadows; and depth of field, using RIB and the C API, introduces the techniques involved in creating shaders, applying textures and using global illumination.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Buch. Condizione: Neu. Neuware -Retrieval of multimedia data is different from retrieval of structured data. A key problem in multimedia databases is search, and the proposed solutions to the problem of multimedia information retrieval span a rather wide spectrum of topics outside the traditional database area, ranging from information retrieval and human¿computer interaction to computer vision and pattern recognition.Based on more than 10 years of teaching experience, Blanken and his coeditors have assembled all the topics that should be covered in advanced undergraduate or graduate courses on multimedia retrieval and multimedia databases. The single chapters of this textbook explain the general architecture of multimedia information retrieval systems; various metadata languages like Dublin Core, RDF, or MPEG; pattern recognition through Markov models, unsupervised learning, and pattern clustering; various indexing approaches to audio and video streams; interaction and control; the protection of content and user privacy; and search effectiveness and efficiency. The authors emphasize high-level features and show how these features are used in mathematical models to support the retrieval process. For each chapter, there¿s detail on further reading, and additional exercises and teaching material is available online.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 392 pp. Englisch.

Buch. Condizione: Neu. Neuware -The past decades have seen significant improvements in 3D imaging where the related techniques and technologies have advanced to a mature state. These exciting developments have sparked increasing interest in industry and academia in the challenges and opportunities afforded by 3D sensing. As a consequence, the emerging area of safety and security related imaging incorporates these important new technologies beyond the limitations of 2D image processing. This book is so far the first that covers the current state of the art in 3D imaging for safety and security. It reports about selected contributions given at the ¿Workshop on Advanced 3D Imaging for Safety and Security¿ held in conjunction with the International Conference on Computer Vision and Pattern Recognition CVPR 2005, June 2005, San Diego, CA. The workshop brought together pioneering academic and industrial researchers in the field of computer vision and image analysis. Special attention was given to advanced 3D imaging technologies in the context of safety and security applications. Comparative evaluation studies showing advantages of 3D imaging over traditional 2D imaging for a given computer vision or pattern recognition task were emphasized. Moreover, additional experts in the field of 3D imaging for safety and security were invited by the editors for a contribution to this book. The book is structured into two parts, each containing five or six chapters on (1) Biometrics and (2) Safety and Security Applications.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 328 pp. Englisch.

Buch. Condizione: Neu. Neuware -The nature and essence of Dark Matter and Dark Energy have become the central issue in modern cosmology over the past years. This extensive volume, an outgrowth of a topical and tutorial summer school, has been set up with the aim of constituting an advanced-level, multi-authored textbook which meets the needs of both postgraduate students and young researchers in the fields of modern cosmology and astrophysics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 452 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Prominent progress in science is inevitably associated with controversies. Thus, young researchers, in particular, have to learn how to persevere during the period of controversy and struggle for acceptance. Unfortunately, the skills needed are not taught in textbooks or monographs, which mostly describe the consensus of contemporary experts.This book, which is based on my own experiences as a scientist, describes the history of the progress made in auroral science and magnetospheric physics by providing examples of ideas, controversies, struggles, acceptance, and success in some instances.Although no general methodology (if any exists) is mentioned, I hope that the reader will learn about the history of progress in auroral science and examples (right or wrong) of dealing with the controversies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 328 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -JavaScript is widely used for simple online applications.This book presents HTML and JavaScript in a way that uniquely meets the needs of students in the sciences and engineering. It explains how to create simple client-side applications for scientific and engineering calculations. It includes many complete HTML/JavaScript examples with science/engineering applications to guide the reader progressively and comprehensively through the subject.This book is specifically targeted at a technical audience-- but not one that is necessarily familiar with a programming language,-- and gives the reader a sufficient understanding of HTML and JavaScript to write their own online applications. The exposition emphasises basic programming principles in a modern Web-oriented environment, making it also highly suitable for an introductory programming course for non-computer science majors. It is also ideal for self-study. There is supplementary website for this book containing code examples and all graphics files.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Stamatis Vassiliadis established the SAMOS workshop in the year 2001¿an event which combines his devotion to computer engineering and his pride for Samos, the island where he was born. The quiet and inspiring northern mo- tainside of this Mediterranean island together with his enthusiasm and warmth created a unique atmosphere that made this event so successful. Stamatis V- siliadis passed away on Saturday, April 7, 2007. The research community wants to express its gratitude to him for the creation of the SAMOS workshop, which will not be the same without him. We would like to dedicate this proceedings volume to the memory of Stamatis Vassiliadis. The SAMOS workshop is an international gathering of highly quali ed - searchers from academia and industry, sharing their ideas during a 3-day lively discussion.Theworkshopmeetingisoneoftwocolocatedevents¿theotherevent being the IC-SAMOS. The workshop is unique in the sense that not only solved research problems are presented and discussed but also (partly) unsolved pr- lems and in-depth topical reviews can be unleashed in the scienti c arena. C- sequently, the workshop provides the participants with an environment where collaboration rather than competition is fostered.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 488 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume contains the proceedings of the 15th International Conference on Conceptual Structures (ICCS 2007), which is an annual event that, for the rst time, was hosted in the UK. Conceptual structures focus on the representation and analysis of concepts, events, actions and objects with applications in - search,softwareengineering,manufacturing and business.The conference brings together researchersin computer science, information technology,arti cial int- ligence, philosophy and a variety of applied disciplines to explore novel ways that information technologies can be leveraged to assist human reasoning and interaction for tangible business or social bene ts. Conceptual structures can be used to augment human intelligence by facilitating knowledge integration, de- sion making, the creation of intelligent software systems and the exploration of implicit structures. The theme for this year¿s conference was ¿Conceptual Structures: Kno- edge Architectures for Smart Applications.¿ Knowledge architectures give rise to smart applications that allow enterprises to share meaning across their int- connected computing resources and to realize transactions that would otherwise remain as lost business opportunities. Conceptual structures and smart appli- tions integrate the creativity of individuals and organizations with the prod- tivity of computers for a meaningful digital future. A focus of ICCS 2007 was on papers that apply conceptual structures in business and technological settings. Other submitted papers covered researchin conceptual structures, which is s- ported by mathematical and computational theory, including formal concept analysis, algorithm design and graph theory, and a variety of software tools. 532 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Economic Systems exhibit complex dynamics evidenced by large-amplitude and aperiodic fluctuations in economic variables, such as foreign exchange rates and stock market prices, indicating that these systems are driven far from the equilibrium. Characterization of the complex behavior of economic cycles, by identifying regular and irregular patterns and regime switching in economic time series, is the key for pattern recognition and forecasting of economic cycles. Statistical analysis of stock markets and foreign exchange markets has demonstrated the intermittent nature of economic time series. A nonlinear model of business cycles is able to simulate intermittency arising from order-chaos and chaos-chaos transitions. This monograph introduces new concepts of unstable periodic orbits and chaotic saddles which are unstable structures embedded in a chaotic attractor, responsible for economic intermittency.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 116 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -For the experienced amateur astronomer who is wondering if there is something useful, valuable, and permanent that can be done with his or her observational skills, the answer is, 'Yes, you can!' This is the book for the experienced amateur astronomer who is ready to take a new step in his or her astronomical journey. Unfortunately, there is no modern text that points curious amateur astronomers to the research possibilities that are open to them. At the 2006 meeting of the Society for Astronomical Sciences, quite a few participants agreed that the lack of such a text was a serious gap in the astronomical book market, and that this gap is impeding their efforts to encourage more amateur astronomers to get involved in research collaborations. This book will fill that gap, and enable more amateur astronomers to add research-type studies to their pursuit of the hobby.Written by an astronomer who is well known amongst the amateur and professional community for the skill and quality of his work, this book describes a wide range of research areas where amateurs are gathering new scientific data that is utilized by professional astronomers. For each research area, the book provides a concise explanation of the purpose and value of the amateurs¿ observations, a description of the equipment that is needed, specific observing procedures, complete data reduction instructions, and an explanation of how, and where, to submit results so that they will be available to the professional users.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 328 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume was prepared to share with a larger audience the exciting ideas and work presented at an ICML 2006 workshop of the same title. Network models have a long history. Sociologists and statisticians made major advances in the 1970s and 1980s, culminating in part with a number of substantial databases and the class of exponential random graph models and related methods in the early 1990s. Physicists and computer scientists came to this domain cons- erably later, but they enriched the array of models and approaches and began to tackle much larger networks and more complex forms of data. Our goal in organ- ing the workshop was to encourage a dialog among people coming from di erent disciplinary perspectives and with di erent methods, models, and tools. Both the workshop and the editing of the proceedings was a truly colla- rative e ort on behalf of all six editors, but three in particular deserve special recognition. Anna Goldenberg and Alice Zheng were the driving force behind the entire enterprise and Edo Airoldi assisted on a number of the more important arrangements.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 208 pp. Englisch.

Buch. Condizione: Neu. Neuware - This book represents the compilation of efforts by researchers across the country, each of whom is dedicated not only to the prevention and elimination of HIV infection, but also to the conduct of research according to the highest ethical pr- ciples. The authors of the case studies have graciously agreed to share their ex- riences in conducting research, which raised questions for them and will motivate us to further inquiry and examination. The views that are presented in this text are diverse and readers may or may not agree with the analyses of the editor-authors or the authors of the case studies. We do not aim for agreement among readers, but rather, the studied analysis of the ethical issues raised in the conduct of HIV research. We clearly emphasize the protection of the individuals participating in such research, as well as their communities, and view research not as an enterprise undertaken by researchers, but rather as a negotiated exchange between researchers, participants, and c- munities that also involves interplay with funding sources, ancillary partners, and governments.

Taschenbuch. Condizione: Neu. Neuware -At the end of the 1980s, Professor August-Wilhelm Scheer developed ARIS as a meta-model for organisational modelling and to provide a procedural model for recording, analysis and optimisation of business processes and their implemen- tion in software systems. In 1993, IDS Scheer released ARIS Toolset; the first version of the ARIS modelling software based upon the ARIS methodology. Today, the ARIS Platform is confirmed by the Gartner Group (2001) and Forrester Research (2006) as the worldwide market leader in business process modelling and BPM software. The Platform consists of more than 20 different products covering the whole BPM lifecycle from business process strategy, to process design and through process implementation to process controlling. The ARIS products and the ARIS method are also delivered through strong partn- ships with companies such as SAP or Oracle. This success shows that IDS Scheer is always aligned to the wishes and requirements of our customers and partners.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 384 pp. Englisch.

Buch. Condizione: Neu. Neuware -Our motivation for writing this book is twofold: First, the theory of waves propagating in randomly layered media has been studied extensively during the last thirty years but the results are scattered in many di erent papers. This theory is now in a mature state, especially in the very interesting regime of separation of scales as introduced by G. Papanicolaou and his coauthors and described in [8], which is a building block for this book. Second, we were motivatedbythe time-reversalexperimentsofM. Finkandhis groupinParis. They were done with ultrasonic waves and have attracted considerable att- tion because of the surprising e ects of enhanced spatial focusing and time compression in random media. An exposition of this work and its appli- tions is presented in [56]. Time reversal experiments were also carried out with sonar arrays in shallow water by W. Kuperman [113] and his group in San Diego. The enhanced spatial focusing and time compression of signals in time reversal in randommedia have many diverse applications in detection and in focused energy delivery on small targets as, for example, in the - struction of kidney stones. Enhanced spatial focusing is also useful in sonar and wireless communications for reducing interference. Time reversal ideas have played an important role in the development of new methods for array imaging in random media as presented in [19].Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 636 pp. Englisch.

Buch. Condizione: Neu. Neuware - Twenty years ago, the objectives of the rst edition of this book were numerous and ambitious:todemystifytheprocessofwellloganalysis;toexaminethephysicalbasis of the multitude of geophysical measurements known collectively as well logging; to clearly lay out the assumptions and approximations routinely used to extract pet- physical information from these geophysical measurements; to expose the vast range of well logging instrumentation and techniques to the larger geophysical community. Finally,therewastheimportantgoalofprovidingatextbookforuniversityandgra- atestudents inGeophysics andPetroleum Engineering, wherenone suitablehad been available before. What's different twenty years later First of all, Well Logging for Earth Scientists is long out of print. The petroleum industry, the major consumer of the geophysical information known as well logging, has changed enormously: technical staffs have been slashed, and hydrocarbons have become increasingly harder to locate, quantify, and produce. In addition, new techniques of drilling high deviation or horizontal wells have engendered a whole new family of measurement devices incorporated into the drilling string that may be used routinely or in situations where access by traditional 'wireline' instruments is dif cult or impossible. Petroleum deposits are becoming scarce and demand is steadily increasing. Massive corporate restructuring and the 'graying' of the workforce have caused the technical competence involved in the search and exploitation of petroleum to become scarce. Although we are only attempting to address this latter scarcity with our textbook, the objectives are still ambitious.

Buch. Condizione: Neu. Neuware -This book tries to sort out the different meanings of uncertainty and to discover their foundations. It shows that uncertainty can be represented using various tools and mental guidelines. Coverage also examines alternative ways to deal with risk and risk attitude concepts. Behavior under uncertainty emerges from this book as something to base more on inquiry and reflection rather than on mere intuition.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 316 pp. Englisch.

Buch. Condizione: Neu. Neuware -Unfair competition law is concerned with fair play in commerce. It is generally regarded as necessary ¿ together with antitrust law ¿ in order to steer competition along an orderly course, and thereby to contribute to promoting an efficient market system that serves the interests of all participants. Nevertheless the significance of unfair competition law varies from one country to another. Whereas in some countries, such as Germany, it is seen as one of the most effective commercial laws, in other countries, such as the United Kingdom, it leads rather a shadowy existence. From the outset, this discrepancy laid in the differences in national legal s- tems. Whilst those continental European countries that possessed a written civil law when instances of unfair competition emerged, more or less successfully attempted to incorporate them in the existing tort law system, protection in the common law countries was restricted to some narrowly defined torts, in particular ¿passing off¿. At this stage one of the few shared convictions was, that the protection of ¿honest entrepreneurs¿ was at issue; on this basis, in 1900, the only regulation at the int- bis national level until now was enacted, Art. 10 of the Paris Convention.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.
