Buch. Zustand: Neu. Neuware - Currently, there is a considerable interest in integrating the results of information extraction in retrieval systems, because of the growing demand for search engines that return precise answers to flexible information queries. Advanced retrieval models satisfy that need and they rely on tools that automatically build a probabilistic model of the content of a (multi-media) document. The book focuses on content recognition in text. It elaborates on the past and current most successful algorithms and their application in a variety of domains (e.g., news filtering, mining of biomedical text, intelligence gathering, competitive intelligence, legal information searching, and processing of informal text). An important part discusses current statistical and machine learning algorithms for information detection and classification and integrates their results in probabilistic retrieval models. The book also reveals a number of ideas towards an advanced understanding and synthesis of textual content.…

Buch. Zustand: Neu. Neuware - Nuclear Transfer Protocols: Cell Reprogramming and Transgenesis is a comprehensive review of nuclear transfer technology in vertebrates, aimed at reprogramming differentiated nuclei and effecting targeted gene transfer. The emphasis here is on providing readily reproducible techniques for the gene- tion of cloned embryos and animals in a number of key research and commercially important vertebrates. Additional chapters provide alternative cutting-edge methods for nuclear transfer, such as zona-free nuclear transfer and serial nuclear transfer. Of immense practical benefit are descriptions of procedures associated with cloning, such as in vitro maturation of oocytes, activation and culture of cloned embryos, maintenance of pregnancy, and neonatal care of clones. Nuclear Transfer Protocols: Cell Reprogramming and Transgenesis also provides an understanding of the factors involved in nuclear reprogramming, which is imperative for the success of cloning. A section dealing with such cloning-related issues as aging and normality of clones is also included making this an essential comprehensive handbook for research and commercial labo- tories involved in, or intending to work on, nuclear transfer. The volume will prove beneficial to molecular biologists, stem cell biologists, clinicians, biotechnologists, students, veterinarians, and animal care technicians involved with reprogramming, nuclear transfer, and transgenesis.…

Buch. Zustand: Neu. Neuware - It is an exciting time to be an artist and artist educator. Networks of schools and artists are being motivated by arts partnerships, a relatively new phenomenon in a field which whilst disparate in its character and practice, is marked by a common intention, to respond effectively and critically to politically driven agendas of accountability, school improvement and pupil attainment. More than ever artists and educators alike have begun to realise the need to develop practices which offer the development of artist educator pedagogies as agencies for change and political action. Understanding the function of reflective practice, the conditions which s- port it and its impact on learning, are addressed throughout this book. We hope that the book will motivate readers, with a diversity of interests and needs, to engage in reflections of their own professional practices and of the practices of the commu- ties in which they work This book is about reflection. The thesis about the field it covers and major premise of this book is that reflection matters at every turn in arts engagement and even more so in educational settings where artist educators share a passion for facilitating and understanding the 'how'of learners engagement with p- ticular art forms. It aims to show ways in which reflection can inform and transform practice in terms of what, when and how reflection is embodied in arts engagement.…

Buch. Zustand: Neu. Neuware - We are presently observing a paradigm change in designing complex SoC as it occurs roughly every twelve years due to the exponentially increasing number of transistors on a chip. This design discontinuity, as all previous ones, is characterized by a move to a higher level of abstraction. This is required to cope with the rapidly increasing design costs. While the present paradigm change shares the move to a higher level of abstraction with all previous ones, there exists also a key difference. For the rst time shrinking geometries do not leadtoacorrespondingincreaseofperformance. InarecenttalkLisaSuofIBM pointed out that in 65nm technology only about 25% of performance increase can be attributed to scaling geometries while the lion share is due to innovative processor architecture [1]. We believe that this fact will revolutionize the entire semiconductor industry. What is the reason for the end of the traditional view of Moore's law It is instructive to look at the major drivers of the semiconductor industry: wireless communications and multimedia. Both areas are characterized by a rapidly increasingdemandofcomputationalpowerinordertoprocessthesophisticated algorithmsnecessarytooptimallyutilizethepreciousresourcebandwidth. The computational power cannot be provided by traditional processor architectures and shared bus type of interconnects. The simple reason for this fact is energy ef ciency: there exist orders of magnitude between the energy ef ciency of an algorithm implemented as a xed functionality computational element and of a software implementation on a processor.…

Buch. Zustand: Neu. Neuware - Calibration Techniques in Nyquist A/D Converters analyses different A/D-converter architectures with an emphasis on the maximum achievable power efficiency. It is shown that in order to achieve high speed and high accuracy at high power efficiency, calibration is required. Calibration reduces the overall power consumption by using the available digital processing capability to relax the demands on critical power hungry analog components. Several calibration techniques are analyzed. The calibration techniques presented in this book are applicable to other analog-to-digital systems, such as those applied in integrated receivers. Further refinements will allow using analog components with less accuracy, which will then be compensated by digital signal processing. The presented methods allow implementing this without introducing a speed or power penalty.…

Buch. Zustand: Neu. Neuware - Crystallographers have an elegant system using definitive notation for describing crystal structures, but it does not serve as well the needs of many others working with crystalline solids. Most chemists, metallurgists, mineralogists, geologists and workers in material sciences need a simple system and notation for describing crystal structures. Structure and Chemistry of Crystalline Solids presents a widely applicable system with simple notation giving important information about the structure and the chemical environment of ions or molecules. It is easily understood and used by those concerned with applications dependent on structure-properties relationships. This book addresses the needs of people working with crystal structures in several fields, while most other books on crystal structures are more than two decades old. Early chapters provide an introduction to crystal structures and symmetry for readers with a variety of backgrounds.…

Kombiprodukt. Zustand: Neu. Neuware - This is the second volume of the new conference series Design Computing and Cognition (DCC) that takes over from and subsumes the successful series Artificial Intelligence in Design (AID) published by Kluwer since 1992. The AID volumes have become standard reference texts for the field. It is expected that the DCC volumes will perform the same role. This new biennial conference series provides an international forum for the presentation and discussion of state-of-the-art and cutting-edge design research. The conference proceedings will form a continuing archive of design computing and cognition research. Design is a fundamentally important topic in disciplines ranging from the more commonly associated fields of architecture and engineering to emerging areas in the social sciences and life sciences. Design is the key to economic competitiveness and the fundamental precursor to objects - both physical and virtual - and services. The conference theme of design computing and cognition recognizes not only the essential relationship between human cognitive processes as models of computation but also how models of computation inspire conceptual realizations of human cognition.…

Buch. Zustand: Neu. Neuware - The thesis of this book is that there are one set of equations that can define any trip between an origin and destination. The idea originally came from work that I did when applying the hydrodynamic analogy to study congested traffic flows in 1981. However, I was disappointed to find out that much of the mathematical work had already been done decades earlier. When I looked for a new application, I realised that shopping centre demand could be like a longitudinal wave, governed by centre opening and closing times. Further, a solution to the differential equation was the gravity model and this suggested that time was somehow part of distance decay. This was published in 1985 and represented a different approach to spatial interaction modelling. The next step was to translate the abstract theory into something that could be tested empirically. To this end, I am grateful to my Ph. D supervisor, Professor Barry Garner who taught me that it is not sufficient just to have a theoretical model. This book is an outcome of this on-going quest to look at how the evolution of the model performs against real world data. This is a far more difficult process than numerical simulations, but the results have been more valuable to policy formulation, and closer to what I think is spatial science. The testing and application of the model required the compilation of shopping centre surveys and an Internet data set.…

Buch. Zustand: Neu. Neuware - La 'cultura geriatrica' - intesa come conoscenza e dominio dei processi di invecchiamento - non ha avuto ancora piena affermazione in campo medico-sanitario. Questo comporta che il più delle volte non si sappia distinguere a pieno il limite tra il fisiologico e il patologico che distinge l'anziano sano con gli inevitabili 'acciacchi' dovuti all'invecchiamento da quello abbisognevole di supporti sanitari e/o assistenziali. Finora si è spesso trattato l'anziano con la cultura dell'adulto, molto diversa da quella geriatrica, con il risultato di considerare malato anche chi ha solo il torto di dimostrare i propri anni. In sostanza, mentre le età della crescita e della piena efficienza sono ben conosciute nei loro aspetti normali e patologici, non altrettanto avviene per l'età della decadenza, per la quale ci si avvale impropriamente di un altro metro di valutazione. Il risultato inevitabile di tutto questo è che gli interventi di supporto per la terza età possono essere scorretti, così come l'impiego delle risorse umane e finanziare ad essa destinate. I vincoli economici sempre più stretti da un lato e il progressivo allargamento della popolazione anziana dall'altro rendono ormai ineludibile l'affermarsi di una vera e propria 'cultura geriatrica' non solo in campo diagnostico radiologico ma anche in tutte le altre discipline specialistiche. Quest'opera vuole andare in questa direzione.…
