A curve or surface (both of which contain an in nite number of points) is described in terms of two objects. One object is a sequence of vertices, which we visualise as a polygon, for curves, or a network of vertices, which we visualise by drawing the edges or faces of the network, for surfaces. The other object is a set of rules for making denser sequences or networks. When applied repeatedly, the denser and denser sequences are claimed to converge to a limit, which is the curve or surface that we want to represent. This book focusses on curves, because the theory for that is complete enough that a book claiming that our understanding is complete is exactly what is needed to stimulate research proving that claim wrong. Also because there are already a number of good books on subdivision surfaces. The way in which the limit curve relates to the polygon, and a lot of interesting properties of the limit curve, depend on the set of rules, and this book is about how one can deduce those properties from the set of rules, and how one can then use that understanding to construct rules which give the properties that one wants.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 232 pp. Englisch.

Neuware -Both classical geometry and modern differential geometry have been active subjects of research throughout the 20th century and lie at the heart of many recent advances in mathematics and physics. The underlying motivating concept for the present book is that it offers readers the elements of a modern geometric culture by means of a whole series of visually appealing unsolved (or recently solved) problems that require the creation of concepts and tools of varying abstraction. Starting with such natural, classical objects as lines, planes, circles, spheres, polygons, polyhedra, curves, surfaces, convex sets, etc., crucial ideas and above all abstract concepts needed for attaining the results are elucidated. These are conceptual notions, each built 'above' the preceding and permitting an increase in abstraction, represented metaphorically by Jacob's ladder with its rungs: the 'ladder' in the Old Testament, that angels ascended and descended.In all this, the aim of the book isto demonstrate to readers the unceasingly renewed spirit of geometry and that even so-called 'elementary' geometry is very much alive and at the very heart of the work of numerous contemporary mathematicians. It is also shown that there are innumerable paths yet to be explored and concepts to be created. The book is visually rich and inviting, so that readers may open it at random places and find much pleasure throughout according their own intuitions and inclinations.Marcel Berger is the author of numerous successful books on geometry, this book once again is addressed to all students and teachers of mathematics with an affinity for geometry.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 848 pp. Englisch.

This cliche embodies the common belief that ran domness has no place in carefully planned methodologies, every step should be spelled out, each i dotted and each t crossed. In discrete mathematics at least, nothing could be further from the truth. Introducing random choices into algorithms can improve their performance. The application of proba bilistic tools has led to the resolution of combinatorial problems which had resisted attack for decades. The chapters in this volume explore and celebrate this fact. Our intention was to bring together, for the first time, accessible discus sions of the disparate ways in which probabilistic ideas are enriching discrete mathematics. These discussions are aimed at mathematicians with a good combinatorial background but require only a passing acquaintance with the basic definitions in probability (e.g. expected value, conditional probability). A reader who already has a firm grasp on the area will be interested in the original research, novel syntheses, and discussions of ongoing developments scattered throughout the book. Some of the most convincing demonstrations of the power of these tech niques are randomized algorithms for estimating quantities which are hard to compute exactly. One example is the randomized algorithm of Dyer, Frieze and Kannan for estimating the volume of a polyhedron. To illustrate these techniques, we consider a simple related problem. Suppose S is some region of the unit square defined by a system of polynomial inequalities: Pi (x. y) ~ o.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 348 pp. Englisch.

Neuware -The contents of this book covers the material required in the Fluid Mechanics Graduate Core Course (MEEN-621) and in Advanced Fluid Mechanics, a Ph. D-level elective course (MEEN-622), both of which I have been teaching at Texas A&M University for the past two decades. While there are numerous undergraduate fluid mechanics texts on the market for engineering students and instructors to choose from, there are only limited texts that comprehensively address the particular needs of graduate engineering fluid mechanics courses. To complement the lecture materials, the instructors more often recommend several texts, each of which treats special topics of fluid mechanics. This circumstance and the need to have a textbook that covers the materials needed in the above courses gave the impetus to provide the graduate engineering community with a coherent textbook that comprehensively addresses their needs for an advanced fluid mechanics text. Although this text book is primarily aimed at mechanical engineering students, it is equally suitable for aerospace engineering, civil engineering, other engineering disciplines, and especially those practicing professionals who perform CFD-simulation on a routine basis and would like to know more about the underlying physics of the commercial codes they use. Furthermore, it is suitable for self study, provided that the reader has a sufficient knowledge of calculus and differential equations. In the past, because of the lack of advanced computational capability, the subject of fluid mechanics was artificially subdivided into inviscid, viscous (laminar, turbulent), incompressible, compressible, subsonic, supersonic and hypersonic flows.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 528 pp. Englisch.

Neuware -An important aspect in the formalisation of common-sense reasoning is the construction of a model of what an agent believes the world to be like to help in her reasoning process. This model is often incomplete or inaccurate, but new information can be used to refine it. The study of techniques that achieve this in a rational way is the task of the discipline of belief revision, with which this book is concerned.There are three key elements to the book's approach. Firstly, the methodology of logic by translation. A specific instance of this is the idea of revision by translation. Revision for a foreign logic is done via its translation into a well-known logic, usually classic logic. Secondly, the technique of meta-level/object-level movement, where we bring some operation defined at the meta-level of a logic into its object level. In this book, we bring the operation of deletion to the object level. Finally, through Labelled Deductive Systems, we use the context of the revision to finetune its operation and illustrate the idea through the presentation of various algorithms.The book is suitable for researchers and postgraduates in the areas of artificial intelligence, database theory, and logic.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 396 pp. Englisch.

Neuware -Steganography is the art and science of hiding information in inconspicuous cover data so that even the existence of a secret message is kept confidential, and steganalysis is the task of detecting secret messages in covers. This research monograph focuses on the role of cover signals, the distinguishing feature that requires us to treat steganography and steganalysis differently from other secrecy techniques. The main theoretical contribution of the book is a proposal to structure approaches to provably secure steganography according to their implied assumptions on the limits of the adversary and on the nature of covers. A further contribution is the emphasis on dealing with heterogeneity in cover distributions, crucial for security analyses. The author's work complements earlier approaches based on information, complexity, probability and signal processing theory, and he presents numerous practical implications. The scientific advances are supported by a survey of the classical steganography literature; a new proposal for a unified terminology and notation that is maintained throughout the book; a critical discussion of the results achieved and their limitations; and an assessment of the possibility of transferring elements of this research's empirical perspective to other domains in information security. The book is suitable for researchers working in cryptography and information security, practitioners in the corporate and national security domains, and graduate students specializing in multimedia security and data hiding.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 304 pp. Englisch.

Neuware -Our planet is currently experiencing substantial changes due to natural phen- ena and direct or indirect human interactions. Observations from space are the only means to monitor and quantify these changes on a global and long-term p- spective. Continuous time series of a large set of Earth system parameters are needed in order to better understand the processes causing these changes, as well as their interactions. This knowledge is needed to build comprehensive Earth s- tem models used for analysis and prediction of the changing Earth. Geodesy and geophysics contribute to the understanding of system Earth through the observation of global parameter sets in space and time, such as tectonic motion, Earth surface deformation, sea level changes and gravity, magnetic and atmospheric elds. In the framework of the German geoscience research and development p- gramme GEOTECHNOLOGIEN, research projects related to the theme ¿Observing the Earth System from Space¿ have been funded within two consecutive phases since 2002, both covering 3 years. The projects address data analysis and model development using the satellite missions CHAMP, GRACE, GOCE and comp- mentary ground or airborne observations. The results of the rst phase projects have been published in the Springer book, titled ¿Observation of the Earth System from Space¿, edited by Flury, Rummel, Reigber, Rothacher, Boedecker and Schreiber in 2006. The present book, titled ¿System Earth via Geodetic-Geophysical Space Techniques¿ summarizes in 40 scienti c papers the results of eight coordinated research projects funded in the second phase of this programme (2005¿2008).Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 616 pp. Englisch.

Through our artistic sensibilities, we try to understand and obtain aesthetic results. Scientifc analysis provides the data to predict which approaches will be successful and safe. Both art and science connote a high level of skill or mastery. At the present time, our literature is replete with descriptions of specifc pro- dures for body contouring. However, there remains a need for a defnitive reference describing the basic principles to address the complete scope of body contouring including the postbariatric patient and their plastic surgery deformities. Dr. Shiffman and Dr. Di Giuseppe saw this need and sought to address the needs of plastic surgeons faced with the complexities of body contouring surgery. This is a comprehensive text aimed at providing multiple perspectives. The numerous sections, which include a- posity and lipolysis, the breast, abdomen, chest, and buttocks, the extremities, and liposuction, offer various approaches from the foremost authors. Indeed it is with a tremendous amount of skill and mastery that Dr. Shiffman and Dr. Di Giuseppe have successfully edited and collated the numerous contributions to this work. In addition, they have authored individually or, in collaboration, over a dozen of the 87 total chapters. Their combined work as editors and authors are e- dent throughout their text. The fnal result is a comprehensive contribution that will beneft all plastic surgeons seeking to improve their approach to body contouring.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 900 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Klinische Pfade und andere patientennahe Prozesse werden oft als rein fachliche Themen erachtet, weil diese im Alltag primär die Arbeit der Ärzte, der Pflegenden und von weiteren Behandelnden direkt betreffen. Die Identifikation von Patienten bzw. das ganze davon abhängende Management von Informationen innerhalb der Patientenpfade wird wiederum häufig als alleinige Aufgabe der IT angesehen. Das Buch stellt diese fachlichen und technischen Ansätze in den breiteren Kontext der in den kommenden Jahren absehbaren Veränderungen des Gesundheitswesens sowie der sich daraus ergebenden Fragestellungen, welche insbesondere die Leistungserbringer des Gesundheitswesens beschäftigen und fordern werden. Die Fähigkeit, Prozesse patientenorientiert zu gestalten wird zu einem wesentlichen Erfolgsfaktor werden. Das methodische Herangehen an die damit zusammenhängenden Fragestellungen wird neben derjenigen der fachlichen und technischen Spezialisten auch die Aufmerksamkeit des Krankenhaus-Managements erfordern.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 268 pp. Deutsch.
