Taschenbuch. Condizione: Neu. Neuware -Vi siete mai chiesti cosa fa un matematico quando scrive freneticamente su un foglio di carta Provate a chiederglielo. Vi sentirete rispondere qualcosa del tipo: 'Sto cercando di dimostrare la natura iperbolica di questa equazione differenziale per poter applicare il metodo delle caratteristiche'.Non avete capito Provate a chiedergli di spiegarvelo più semplicemente. La risposta sarà: 'Allora. Ecco. Come posso dire. Sto cercando di dimostrare che questo coso qui (indica un formulone) appartiene a una certa categoria di equazioni in cui la soluzione si propaga da un certo dato iniziale lungo delle curve particolari.'Inutile insistere, non vi resta che andarvene. La matematica vi ha respinto un'altra volta.Ma una soluzione esiste ed è unica: leggere questo libro e lasciarvi guidare nell¿incantato mondo dell'alta matematica senza per questo fare alta matematica. Capirete finalmente cosa studiano i matematici, cosa pensano, cosa li appassiona e in quale strano mondo n-dimensionale vivono. Dedicato a tutti coloro che vorrebbero studiare matematica ma che non lo hanno mai (o ancora) fatto, questo libro vi convincerà che la matematica è il perfetto connubio tra scienza e arte, tra curiosità e fantasia, tra scoperta ed invenzione.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Italienisch.

Taschenbuch. Condizione: Neu. Neuware -Adaptive detection of signals embedded in correlated Gaussian noise has been an active field of research in the last decades. This topic is important in many areas of signal processing such as, just to give some examples, radar, sonar, communications, and hyperspectral imaging. Most of the existing adaptive algorithms have been designed following the lead of the derivation of Kelly's detector which assumes perfect knowledge of the target steering vector. However, in realistic scenarios, mismatches are likely to occur due to both environmental and instrumental factors. When a mismatched signal is present in the data under test, conventional algorithms may suffer severe performance degradation. The presence of strong interferers in the cell under test makes the detection task even more challenging. An effective way to cope with this scenario relies on the use of 'tunable' detectors, i.e., detectors capable of changing their directivity through the tuning of proper parameters. The aim of this book is to present some recent advances in the design of tunable detectors and the focus is on the so-called two-stage detectors, i.e., adaptive algorithms obtained cascading two detectors with opposite behaviors. We derive exact closed-form expressions for the resulting probability of false alarm and the probability of detection for both matched and mismatched signals embedded in homogeneous Gaussian noise. It turns out that such solutions guarantee a wide operational range in terms of tunability while retaining, at the same time, an overall performance in presence of matched signals commensurate with Kelly's detector.

Taschenbuch. Condizione: Neu. Neuware -The characterization of combinatorial or geometric structures in terms of their groups of automorphisms has attracted considerable interest in the last decades and is now commonly viewed as a natural generalization of Felix Klein¿s Erlangen program(1872).Inaddition,especiallyfor nitestructures,importantapplications to practical topics such as design theory, coding theory and cryptography have made the eld even more attractive. The subject matter of this research monograph is the study and class- cation of ag-transitive Steiner designs, that is, combinatorial t-(v,k,1) designs which admit a group of automorphisms acting transitively on incident point-block pairs. As a consequence of the classi cation of the nite simple groups, it has been possible in recent years to characterize Steiner t-designs, mainly for t=2,adm- ting groups of automorphisms with su ciently strong symmetry properties. For Steiner 2-designs, arguably the most general results have been the classi cation of all point 2-transitive Steiner 2-designs in 1985 by W. M. Kantor, and the almost complete determination of all ag-transitive Steiner 2-designs announced in 1990 byF.Buekenhout,A.Delandtsheer,J.Doyen,P.B.Kleidman,M.W.Liebeck, and J. Saxl. However, despite the classi cation of the nite simple groups, for Steiner t-designs witht> 2 most of the characterizations of these types have remained long-standing challenging problems. Speci cally, the determination of all - transitive Steiner t-designs with 3 t 6 has been of particular interest and object of research for more than 40 years.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 136 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The sequel to the popular lecture book entitled Biomedical Image Analysis: Tracking, this book on Biomedical Image Analysis: Segmentation tackles the challenging task of segmenting biological and medical images. The problem of partitioning multidimensional biomedical data into meaningful regions is perhaps the main roadblock in the automation of biomedical image analysis. Whether the modality of choice is MRI, PET, ultrasound, SPECT, CT, or one of a myriad of microscopy platforms, image segmentation is a vital step in analyzing the constituent biological or medical targets. This book provides a state-of-the-art, comprehensive look at biomedical image segmentation that is accessible to well-equipped undergraduates, graduate students, and research professionals in the biology, biomedical, medical, and engineering fields. Active model methods that have emerged in the last few years are a focus of the book, including parametric active contour and active surface models, active shape models,and geometric active contours that adapt to the image topology. Additionally, Biomedical Image Analysis: Segmentation details attractive new methods that use graph theory in segmentation of biomedical imagery. Finally, the use of exciting new scale space tools in biomedical image analysis is reported.

Taschenbuch. Condizione: Neu. Neuware -Over the last 10¿20 years, there has been an increasing appreciation of the need to manage individual risk factors for cardiovascular disease (CVD) in the context of overall cv risk rather than on the basis of the absolute level of any given risk factor. This approach has given rise to the misnomer ¿global risk¿ and gen- ated extensive ¿lip-service¿ around this more broad-minded approach to managing risk factors and the prevention of CVD. This short book was devised with the idea of providing a practical summary of the rationale for management based on estimated total CV risk and the various methods associated with so-doing. Practical issues are addressed including treatment thresholds and targets for the major risk factors on which we routinely intervene, and a brief descr- tion of the major means of these interventions is provided. Whilst a multifactorial approach to CV prevention is logical and reflects the pathophysiological processes which underpin the formation of athe- sclerosis, the evidence base to guide practice using estimated CV risk (¿global risk¿) as a threshold for intervention is essentially non-existent. Meanwhile, pending supportive evidence from randomized trials, prac- cal, pragmatic, and cost-effective approaches to preventing CVD, which is the current biggest contributor to global mortality and burden of disease, is urgently required. The hope is that this book may make a small contribution toward reducing the horrendous burden which CVD currently imposes on the world.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 100 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.

Buch. Condizione: Neu. Neuware -Were I to take an iron gun, And re it o towards the sun; I grant ¿twould reach its mark at last, But not till many years had passed. But should that bullet change its force, And to the planets take its course, ¿Twould never reach the nearest star, Because it is so very far. from FACTS by Lewis Carroll [55] Let me begin by describing the two purposes which prompted me to write this monograph. This is a book about algebraic topology and more especially about homotopy theory. Since the inception of algebraic topology [217] the study of homotopy classes of continuous maps between spheres has enjoyed a very exc- n n tional, central role. As is well known, for homotopy classes of maps f : S S with n 1 the sole homotopy invariant is the degree, which characterises the homotopy class completely. The search for a continuous map between spheres of di erent dimensions and not homotopic to the constant map had to wait for its resolution until the remarkable paper of Heinz Hopf [111]. In retrospect, nding 3 an example was rather easy because there is a canonical quotient map from S to 3 1 1 2 theorbitspaceofthe freecircleactionS /S =CP = S .Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 260 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Welcome to the proceedings of PATMOS 2008, the 18th in a series of int- national workshops. PATMOS 2008 was organized by INESC-ID / IST - TU Lisbon, Portugal, with sponsorship by Cadence, IBM, Chipidea, and Tecmic, and technical co-sponsorship by the IEEE. Over the years, PATMOS has evolved into an important European event, where researchers from both industry and academia discuss and investigate the emerging challenges in future and contemporary applications, design meth- ologies, and tools required for the development of the upcoming generations of integrated circuits and systems. The technical program of PATMOS 2008 c- tained state-of-the-art technical contributions, three invited talks, and a special session on recon gurable architectures. The technical program focused on t- ing, performance and power consumption, as well as architectural aspects with particular emphasis on modeling, design, characterization, analysis and op- mization in the nanometer era. The Technical Program Committee, with the assistance of additional expert reviewers, selected the 41 papers presented at PATMOS. The papers were - ganized into 7 oral sessions (with a total of 31 papers) and 2 poster sessions (with a total of 10 papers). As is customary for the PATMOS workshops, full papers were required for review, and a minimum of three reviews were received per manuscript.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 480 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book constitutes the thoroughly refereed post-conferenceproceedings of the COST Action 2102 and euCognition supported international school on Multimodal Signals: 'Cognitive and Algorithmic Issues' held in Vietri sul Mare, Italy, in April 2008. The 34 revised full papers presented were carefully reviewed and selected from participants¿ contributions and invited lectures given at the workshop.

The papers deal with the theoretical and computational issue of defining algorithms, programming languages, and determinist models to recognize and synthesize multimodal signals. These are facial and vocal expressions of emotions, tones of voice, gestures, eye contact, spatial arrangements, patterns of touch, expressive movements, writing patterns, and cultural differences, in anticipation of the implementation of intelligent avatars and interactive dialogue systems that could be exploited to improve user access to future telecommunication services. The second part of the volume, on Verbal and Nonverbal Communication Signals, presents 20 original studies devoted to the modeling of timing synchronisation between speech production, gestures, facial and head movements in human communicative expressions and on their mutual contribution for an effective communication. 364 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Managing uncertainty in new product development projects for improved valuation and decision making is one of the most complex and challenging problems in operations management. It is important for any corporation depending on the success of new products and innovations. This work shows how uncertainty can be handled and partly resolved by conducting an information update during the development process. It is one of the first comprehensive models that combine statistical decision theory in form of Bayesian analysis with a real options framework for projects exposed to different sources of uncertainty. The proposed framework makes an important theoretical contribution in addressing this problem, while at the same time being of significant value to managers who face the difficult task of evaluating and managing complex product development projects.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Leadership in Healthcare opens up the world of leadership studies to all healthcare professionals. Physicians, nurses, and other healthcare professionals spend thousands of hours studying the science and technology of healthcare, and years or even decades putting into practice recent findings in molecular biology, clinical diagnostics, and therapeutics. By contrast, the topic of leadership and the traits of effective leaders tend to receive remarkably little attention. Yet no less vital than an understanding of how to interpret diagnostic tests and design care plans is a grasp of healthcare's organizational side, including the operation of multidisciplinary care teams, academic departments, and hospitals. If patient care, education, research, and professional service are to thrive in years to come, we must do a better job of preparing healthcare professionals to lead effectively.Composed of insightful and thought-provoking essays on the key facets of leadership, this book is designed to meet the needs of several important constituencies, including educators of health professionals who wish to incorporate leadership into their educational programs; health professional organizations seeking to enhance their members' leadership effectiveness, and individual health professionals who wish to embrace leadership in their personal and professional lives.This book represents a vital resource for health professionals who wish to enhance the quality of leadership in health professions education, practice, and professional development.In addition to regularly caring for patients, Richard Gunderman, MD PhD MPH brings to this discussion a wealth of personal experience in professional and organizational leadership.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 216 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Integration theory deals with extended real-valued, vector-valued, or operator-valued measures and functions. Different approaches are applied in each of these cases using different techniques. The order structure of the (extended) real number system is used for real-valued functions and measures whereas suprema and infima are replaced with topological limits in the vector-valued case.A novel approach employing more general structures, locally convex cones, which are natural generalizations of locally convex vector spaces, is introduced here. This setting allows developing a general theory of integration which simultaneously deals with all of the above-mentioned cases.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.

Hidden and mysterious, with faces that were dreamy and abstracted, or distracted, or pensive. Caught up in their thoughts, caught up in their space, a space that was distant and that only they could understand. Elusive and yet there, in front of me. Certainly, it was them, the six mathematicians of the Mathematica series by Mimmo Paladino. Tinkers of numbers and shapes. For ten years we have been searching for the mathematicians there. In Venice, the favourite place. An aura of mystery surrounds them, otherwise what kind of mathematicians would they be! Mysterious, dreamy, absent, absorbed are the faces of Paladinös mathemat- V icians. Te voices of ve Sardinian shepherds intone the Kyrie,the Libera Me Domine, the Sanctus.

Taschenbuch. Condizione: Neu. Neuware -Mobile Response 2008, the Second International Workshop on Mobile Infor- tion Technology for Emergency Response, aimed at a focussed exchange on how mobile information technology can be e ectively used to the bene t of em- gency response. The gap between the great potential bene t that usable mobile IT could yield in the domain of emergency response and the speci c design challenges for such technologies in this particularly unforgiving domain was the foundation of our decision to create a venue for researchers and practitioners from di erent disciplines. During this year¿s workshopthe latest approachesand technical solutions in the area of mobile information technology for emergency response planning and execution were presented and demonstrated. We invited participation from research, industry and public rescue orga- zations to enable an in-depth discussion of the opportunities and drawbacks of new digital technologies for emergency response. The call for papers for the second Mobile Response workshop attracted over 25 submissions from 11 d- ferent countries, including international submissions from the USA, Brazil and Japan.AninternationalProgramCommitteewithexpertsonmobileinformation technology, emergency response and emergency response equipment selected 12 submissions for presentation during the workshop.

Buch. 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.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Englisch.

Buch. Condizione: Neu. Neuware -Overview and Goals This book describes how to visualize and compare bacterial genomes. Sequencing technologies are becoming so inexpensive that soon going for a cup of coffee will be more expensive than sequencing a bacterial genome. Thus, there is a very real and pressing need for high-throughput computational methods to compare hundreds and thousands of bacterial genomes. It is a long road from molecular biology to systems biology, and in a sense this text can be thought of as a path bridging these elds. The goal of this book is to p- vide a coherent set of tools and a methodological framework for starting with raw DNA sequences and producing fully annotated genome sequences, and then using these to build up and test models about groups of interacting organisms within an environment or ecological niche. Organization and Features The text is divided into four main parts: Introduction, Comparative Genomics, Transcriptomics and Proteomics, and nally Microbial Communities. The rst ve chapters are introductions of various sorts. Each of these chapters represents an introduction to a speci c scienti c eld, to bring all readers up to the same basic level before proceeding on to the methods of comparing genomes. First, a brief overview of molecular biology and of the concept of sequences as biological inf- mation are given.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 288 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.

Taschenbuch. Condizione: Neu. Neuware -This book is based on notes for a master¿s course given at Queen Mary, University of London, in the 1998/9 session. Such courses in London are quite short, and the course consisted essentially of the material in the rst three chapters, together with a two-hour lecture on connections with group theory. Chapter 5 is a considerably expanded version of this. For the course, the main sources were the books by Hopcroft and Ullman ([20]), by Cohen ([4]), and by Epstein et al. ([7]). Some use was also made of a later book by Hopcroft and Ullman ([21]). The ulterior motive in the rst three chapters is to give a rigorous proof that various notions of recursively enumerable language are equivalent. Three such notions are considered. These are: generated by a type 0 grammar, recognised by a Turing machine (deterministic or not) and de ned by means of a Godel ¿ numbering, having de ned ¿recursively enumerable¿ for sets of natural numbers. It is hoped that this has been achieved without too many ar- ments using complicated notation. This is a problem with the entire subject, and it is important to understand the idea of the proof, which is often quite simple. Two particular places that are heavy going are the proof at the end of Chapter 1 that a language recognised by a Turing machine is type 0, and the proof in Chapter 2 that a Turing machine computable function is partial recursive.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 168 pp. Englisch.
