In 1982 Tsfasman, Vladut and Zink, using algebraic geometry and ideas of Goppa, constructed a seqeunce of codes that exceed the Gilbert-Varshamov bound. The result was considered sensational. Furthermore, it was surprising to see these unrelated areas of mathematics collaborating. The aim of this course is to give an introduction to coding theory and to sketch the ideas of algebraic geometry that led to the new result. Finally, a number of applications of these methods of algebraic geometry to coding theory are given. Since this is a new area, there are presently no references where one can find a more extensive treatment of all the material. However, both for algebraic geometry and for coding theory excellent textbooks are available. The combination ofthe two subjects can only be found in a number ofsurvey papers. A book by C.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - This volume offers researchers the opportunity to catch up with important developments in the field of numerical analysis and scientific computing and to get in touch with state-of-the-art numerical techniques. The book has three parts. The first one is devoted to the use of wavelets to derive some new approaches in the numerical solution of PDEs, showing in particular how the possibility of writing equivalent norms for the scale of Besov spaces allows to develop some new methods. The second part provides an overview of the modern finite-volume and finite-difference shock-capturing schemes for systems of conservation and balance laws, with emphasis on providing a unified view of such schemes by identifying the essential aspects of their construction. In the last part a general introduction is given to the discontinuous Galerkin methods for solving some classes of PDEs, discussing cell entropy inequalities, nonlinear stability and error estimates.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - 'It is not the consciousness of men that defines their existence, but, on the contrary, their social existence determines their consciousness.' Karl Marx In recent years, several researchers have argued that the design of multi-agent sys tems (MAS) in complex, open environments can benefit from social abstractions in order to cope with problems in coordination, cooperation and trust among agents, problems which are also present in human societies. The agent-mediated electronic institutions (e-institutions for short) is a new and promising field which focuses in the concepts of norms and institutions in order to pro vide normative frameworks to restrict or guide the behaviour of (software) agents. The main idea is that the interactions among a group of (software) agents are ruled by a set of explicit norms expressed in a computational language representation that agents can interpret. Such norms should not be considered as a negative constraining factor but as an aid that guides the agents' choices and reduces the complexity ofthe environment making the behaviour of other agents more predictable.

Taschenbuch. Condizione: Neu. Neuware - The special issue contains contributions presented at the international workshop Seismic waves in laterally inhomogeneous media IV, which was held at the Castle of Trest, Czech Republic, May 22-27, 1995. The workshop, which was attended by about 100 seismologists from more than 10 countries, was devoted mainly to the current state of theoretical and computational means of study of seismic wave propagation in complex structures. The special issue can be of interest for theoretical, global and explorational seismologists. The first part contains papers dealing with the study and the use of various methods of solving forward and inverse problems in complicated structures. Among other methods, discrete-wave number method, the finite-difference method, the edge-wave supperposition method and the ray method are studied and used. Most papers contained in the second part are related to the ray method. The most important topics are two-point ray tracing, grid calculations of travel times and amplitudes and seismic wave propagation in anisotropic media.

The Mediterranean region is not only the site of shallow dispersed seismic activity, it is also the site of localized intermediate depth seismic activity, and of some rare deeper events. Active subduc tion is clearly at the origin of Greek intermediate depth seismicity, while the deep activity under Calabria and the Vrancea region in Romania is clearly related to downgoing slabs that have long remained active after the arrest of subduction. The origin of the intermediate and very deep seismicity below Spain is a considerably more complex problem. Several possible explanations of the intermediate depth activity to about 110 km have been proposed, but the origin of the deep (650 km) events studied by BURFORN et a1. remains a mystery since this is the only source of deep activity that is not related in an obvious way to a subduction zone. The problem of seismic source mechanism and seismotectonics cannot be completely separated from that of the mechanical origin of earthquakes. Recent work on this subject has revealed the intimate relation between fault geometry, as observed by field geologists, and the results of inversion of source process from seismic data in the far-field or in the near-field.

Character recognition has shown the most practical success. Furthermore, the techniques span much more sophisticated applications such as interpretation of biomedical images and X-ray films, measurement of images in nuclear physics, processing of a large volume of pictorial data sent from the satellites, etc. The particular problem attacked in this thesis is computer analysis and identification of human faces. Pictures of human faces are successfully analyzed by a computer program which extracts face feature points, such as nose, mouth, eyes, and so on. The program was tested with more than 800 photographs The research has been done with main emphasis on the method of how to incorporate the picture structures into the picture anlysis program. The success of the program is due to the employment of a flexible picture analysis scheme with feedbacks, which will be described in the next chapter. An experiment on face identification of 20 people was also conducted. I-1. Picture Analysis and Recognition- New Aspects When shown the pictures of the human face of Fig. 1-1, we can immediately tell the positions of the nose, mouth and eyes; and more- over, we can say that both pictures surely portray the same person. Picture analysis and recognition by computer concerns itself with this type of two-dimensional image processing. In this thesis, I selected human-face pictures as objects of processing.

Druck auf Anfrage Neuware - Printed after ordering - Clinical Trial Registries: A Practical Guide for Sponsors and Researchers of Medicinal Products is a necessary addition to the library of all researchers who plan to publish their results in top-tier, peer-reviewed journals. ICMJE editors and other journal editors require registration of clinical trial information on publicly available Web sites before enrollment of study subjects and some countries and regions also require this information, as well as timely publication of study results. Not only does this book discuss the genesis of these requirements, it also provides practical information for researchers and sponsors on how to establish a workflow for a clinical registry project, how to file to a registry, and how to post results. More than 25 current Web addresses for registries are provided as well asa comprehensive annotated bibliography of papers on the topic of clinical trial registries. This book is a valuable source of information for all sponsors of medicinal products.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - The complexity of Information Technology (IT) systems has been steadily incre- ing in the past decades. In October 2001, IBM released the 'Autonomic Computing Manifesto' observing that current applications have reached the size of millions of lines of code, while physical infrastructures include thousands of heterogeneous servers requiring skilled IT professionals to install, con gure, tune, and maintain. System complexity has been recognized as the main obstacle to the further advan- ment of IT technology. The basic idea of Autonomic Computing is to develop IT systems that are able to manage themselves, as the human autonomic nervous system governs basic body functions such as heart rate or body temperature, thus freeing the conscious brain- IT administrators-from the burden of dealing with low-level vital functions. Autonomic Computing systems can be implemented by introducing autonomic controllers which continuously monitor, analyze, plan, and execute (the famous MAPE cycle) recon guration actions on the system components. Monitoring acti- ties are deployed to measure the workload and performance metrics of each running component so as to identify system faults. The goal of the analysis activities is to determine the status of components from the monitoring data, and to forecast - ture conditions based on historical observations. Finally, plan and execute activities aim at deciding and actuating the next system con guration, for example, deciding whether to accept or reject new requests, determining the best application to servers assignment, in order to the achieve the self-optimization goals.

At first glance, it might seem to indicate the relationship between what buildings look like and how they stand up. This is indeed one aspect of what we are concerned with here. But on a deeper level, the fundamental concept of structure is what connects architecture to mathematics. Both architecture and mathematics are highly structured formal systems expressed through a symbolic language. For architecture, the generating structure might be geometrical, musical, modular, or fractal. Once we understand the nature of the structure underlying the design, we are able to 'read' the meaning inherent in the architectural forms. The papers in this issue all explore themes of structure in different ways.

Druck auf Anfrage Neuware - Printed after ordering - Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most commonly prescribed groups of drugs in the community. This reflects the high frequency of rheumatic complaints but may in part be due to the relative non efficacy of these drugs. Since the introduction of ibuprofen, the first new NSAID to compete with aspirin, phenylbutazone and indomethacin, there has been a proliferation of new NSAIDs of differing chemical classes but an apparent similar spectrum of action. Despite the fact that these drugs are thought to work by an apparent common mechanism of action (suppression of prostaglandin synthetase activity) continued development of these drugs occurs. There exists at present a conflict between the pharmaceutical industry with its attempts to introduce new NSAIDs and drug regulatory authorities who are generally not convinced of the need for additional drugs of_ this class. The practising clinician regards a variety of NSAIDs as necessary to enable pain relief to be optimised.with minimal adverse effects. With respect to the dilemma of how many NSAIDs are really necessary surprisingly little convincing data is available to assist in resolving this issue. It was therefore decided to hold a satellite meeting to the XVIth International League Against Rheumatism Conference in May 1985.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Underwater exploration is a fascinating activity because of the richness of sea life, the beautiful colors, and the contrast with terrestrial life. It can be done by diving or snorkeling -today there is fine equipment for diving and taking underwater pictures and, apart from being a source of pleasure, it forms the basis of modern ecological and behavioral marine studies. Diving is an emotional activity. The silence of the submarine world, only interrupted by breathing, has more than once evoked the monsters of the fabulous tales of my youth. Maybe because, although much time has elapsed since then, I still have a youth's ability to evaluate everything for the fascination it conveys. However, no more than that can be gained from underwater watehing. I am not saying that this is destined to be a futile exercise. Picasso watched sea urchins much in the same way while revealing their quintessence in his paintings at the Castle of Antibes. What I mean is that today marine life can also be viewed from the perspective of the natural products involved. This knowledge, subsequent to Picasso's time, adds much to the overall picture.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Regional seismograms are dominated by the phases Pn, Pg, Sn, and Lg. More often Sn and Lg are used to infer the attenuation structure of the lithosphere. The seismic phase Sn is a high-frequency shear-wave (typically from 1 to 4 Hz and occasionally higher) that travels in the lithospheric mantle above the negative velocity gradient which usually marks the lithosphere-asthenosphere boundary. Sn has been reported out to distances of 35° (e. g. , MOLNAR and OLIVER, 1969; HUESTIS et aI. , 1973). Sn arrives as a high-frequency wave train lasting tens of seconds and up to 1 to 2 minutes. Sn velocities are typically 4. 7 km/s in stable continental and oceanic lithosphere (HUESTIS et al. , 1973) and as low as 4. 3 km/s (KADINSKY-CADE et al. , 1981) in more tectonically active regions. Lg is a complex short period guided wave consisting of high-frequency P and S energy which travels primarily in the earth's crust at frequencies typically between 0. 5 and 5 Hz. It has been modeled as higher-mode Love and Rayleigh waves as well as a sequence of multiply reflected post-critical S waves trapped in a crustal guide (BOUCHON, 1982; KENNETT, 1986; BOSTOCK and KENNETT, 1990). Lg has been observed not to propagate in oceanic or very thin continental crust (PRESS and EWING, 1952; SEARLE, 1975; ZHANG and LAY, 1995).

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - The present doctoral thesis was developed within the framework of the research project 'Deformation Capacity of Structural Concrete'. This project aims at developing a consistent and experimentally verified theory of the deformation capacity of structural concrete. Previous work included the development of a theoretical model, the so-called Tension Chord Model, which allows a comprehensive description of the load-deforma tion behaviour of tension members in non-prestressed and prestressed concrete struc tures. The present work focuses on a new theoretical model, the so-called Cracked Mem brane Model. For members subjected to in-plane forces this new model combines the ba sic concepts of the modified compression field theory and the tension chord model. Crack spacings and tension stiffening effects in cracked membranes are determined from first principles and the link to plasticity theory methods is maintained since equilibrium conditions are formulated in terms of stresses at the cracks rather than average stresses between the cracks. The research project 'Deformation Capacity of Structural Concrete' has been funded by the Swiss National Science Foundation and the Association of the Swiss Cement Pro ducers. This support is gratefully acknowledged. Zurich, July 1998 Prof. Dr. Peter Marti Abstract This thesis aims at contributing to a better understanding of the load-carrying and defor mational behaviour of structural concrete subjected to in-plane shear and normal forces.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - n This book deals with several aspects of fractal geometry in which are closely connected with Fourier analysis, function spaces, and appropriate (pseudo)differ- tial operators. It emerged quite recently that some modern techniques in the theory of function spaces are intimately related to methods in fractal geometry. Special attention is paid to spectral properties of fractal (pseudo)differential operators; in particular we shall play the drum with a fractal layer. In some sense this book may be considered as the fractal twin of [ET96], where we developed adequate methods to handle spectral problems of degenerate n pseudodifferential operators in and in bounded domains. Besides a few special properties of function spaces we relied there on sharp estimates of entropy numbers of compact embeddings between these spaces and their relations to the distribution of eigenvalues. Some of the main assertions of the present book are based on just these techniques but now in a fractal setting. Since virtually nothing of these new methods is available in literature, a substantial part of what we have to say deals with recent developments in the theory of function spaces, also for their own sake. In this respect the book might also be considered as a continuation of [Tri83] and [Tri92].

Druck auf Anfrage Neuware - Printed after ordering - In the last years electronic markets, especially online auctions, have become very popular and received more and more attention in both, business (B2B) as well as in public practice (B2C and C2C). Science, however, is still far from having studied all phenomena and effects which can be observed on electronic markets. Apart from theoretic analysis, other approaches are necessary to evaluate and understand market effects. This book shows that and how software agents can be used to simulate bidding behaviour in electronic auctions.The main emphasis of this book is to apply computational economics to market theory. It summarizes the most common and up-to-date agent-based simulation methods and tools and develops the simulation software AMASE. On basis of the introduced methods a model is established to simulate bidding behaviour under uncertainty.The book addresses researchers, computer scientists, economists and students who are interested in applying agent-based computational methods to electronic markets. It helps to learn more about simulations in economics in general and common agent-based methods and tools in particular. The reader finds basic definitions and learns how to build an appropriate model for the posed research question. It is the first time that quantitative results are presented for the problem of valuation uncertainty. These results significantly contribute to existing research in computational economics and supplements interesting research aspects.

We also want to propose a speci c way to introduce concepts that have arisen from the heyday of the Greek school of geometry to the present day. We workwithcoordinatemodels,sincethis facilitatestheuseofalgebraicandanalytic results, and we follow the viewpoint proposed by Felix Klein in the 19th century, of studying geometry via groups of symmetries of the space in question. We intend this book to be both an introduction to the subject addressed to undergraduate students in mathematics and physics, and a useful text-book for mathematicians and scientists in general who want to learn the basics of classical geometry: Euclidean, a ne, elliptic, hyperbolic and projective geometry. These are all presented in a uni ed way and the essential content of this book may be covered in a single semester, though a longer period of study would allow the student to grasp and assimilate better the material in it.

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Communication networks are very complex and interdependent systems requiring complicated management and control operations under strict resource and time constraints. A finite number of network components with limited capacities need to be shared for dynamically allocating a high number of traffic demands. Moreover, coordination of peer provider is required whenever these demands span domains controlled by distinct operators. In this context, traditional human-driven management is becoming increasingly inadequate to cope with the growing heterogeneity of actors, services and technologies populating the current deregulated market.This book proposes a novel approach to improve multi-provider interactions based on the coordination of autonomous and self-motivated software entities acting on behalf of distinct operators. Coordination is achieved by means of distributed constraint satisfaction techniques integrated within economic mechanisms, which enable automated negotiations to take place. This allows software agents to find efficient allocations of service demands spanning several networks without having to reveal strategic or confidential data. In addition, a novel way of addressing resource allocation and pricing in a compact framework is made possible by the use of powerful resource abstraction techniques.The book is addressed to researchers in the area of agent technology, automated negotiation, distributed constraint satisfaction, and networking, in particular for what concerns resource allocation and pricing. Furthermore, it should be a valuable resource for both network and service providers.

Buch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book is about a side of Isaac Newton's character that has not been examined - Isaac Newton as architect as demonstrated by his reconstruction of Solomon's Temple. Although it is well known that Isaac Newton worked on the Temple, and this is mentioned in most of his biographies and in articles on the religious aspects of this work, however, there is no research on Newton's architectural work. This book not only recreates Newton's reconstruction of the Temple but it also considers how his work on the Temple interlinks with his other interests of science, chronology, prophecy and theology. In addition the book contains the first translation of Introduction to the Lexicon of the Prophets, Part two: About the appearance of the Jewish Temple commonly known by its call name Babson 0434. This work will appeal not only to scholars of science and architectural history but also to scholars of the seventeenth and eighteenth centuries' history of ideas.
