Approximate Deconvolution Models of Turbulence: Analysis, Phenomenology and Numerical Analysis (Lecture Notes in Mathematics #2042)
by William J. Layton Leo G. RebholzThis volume presents a mathematical development of a recent approach to the modeling and simulation of turbulent flows based on methods for the approximate solution of inverse problems. The resulting Approximate Deconvolution Models or ADMs have some advantages over more commonly used turbulence models – as well as some disadvantages. Our goal in this book is to provide a clear and complete mathematical development of ADMs, while pointing out the difficulties that remain. In order to do so, we present the analytical theory of ADMs, along with its connections, motivations and complements in the phenomenology of and algorithms for ADMs.
Approximate Global Convergence and Adaptivity for Coefficient Inverse Problems
by Larisa Beilina Michael Victor KlibanovApproximate Global Convergence and Adaptivity for Coefficient Inverse Problems is the first book in which two new concepts of numerical solutions of multidimensional Coefficient Inverse Problems (CIPs) for a hyperbolic Partial Differential Equation (PDE) are presented: Approximate Global Convergence and the Adaptive Finite Element Method (adaptivity for brevity). Two central questions for CIPs are addressed: How to obtain a good approximations for the exact solution without any knowledge of a small neighborhood of this solution, and how to refine it given the approximation. The book also combines analytical convergence results with recipes for various numerical implementations of developed algorithms. The developed technique is applied to two types of blind experimental data, which are collected both in a laboratory and in the field. The result for the blind backscattering experimental data collected in the field addresses a real world problem of imaging of shallow explosives.

Approximate Models of Mechanics of Composites: An Asymptotic Approach
by Jan Awrejcewicz Igor V. Andrianov Galina A. StarushenkoApproximate Models of Mechanics of Composites: An Asymptotic Approach is an essential guide to constructing asymptotic models and mathematical methods to correctly identify the mechanical behavior of composites. It provides methodology for predicting and evaluating composite behavior in various structures, leading to accurate mathematical and physical assessments. The book estimates the error of approximations through comparing asymptotic solutions with the results of numerical and analytical solutions to gain a holistic view of the data. The authors have developed asymptotic models based on mathematical and physical rigorous approaches, which include three-phase models of fibrous composites, a modernized three-phase composite model with cylindrical inclusions, and models of two-dimensional composites of hexagonal structure. Also covered are two-phase models of composites related to the Maxwell formula and a percolation transition model for elastic problems based on the self-consistency method and Padé approximations. By obtaining analytical expressions to effectively characterize composite materials, their physical and geometric parameters can be accurately assessed. This book suits engineers and students working in material science, mechanical engineering, physics, and mathematics, as well as composite materials in industries such as construction, transport, aerospace, and chemical engineering.

Approximate Reasoning by Parts: An Introduction to Rough Mereology (Intelligent Systems Reference Library #20)
by Lech PolkowskiThe monograph offers a view on Rough Mereology, a tool for reasoning under uncertainty, which goes back to Mereology, formulated in terms of parts by Lesniewski, and borrows from Fuzzy Set Theory and Rough Set Theory ideas of the containment to a degree. The result is a theory based on the notion of a part to a degree. One can invoke here a formula Rough: Rough Mereology : Mereology = Fuzzy Set Theory : Set Theory. As with Mereology, Rough Mereology finds important applications in problems of Spatial Reasoning, illustrated in this monograph with examples from Behavioral Robotics. Due to its involvement with concepts, Rough Mereology offers new approaches to Granular Computing, Classifier and Decision Synthesis, Logics for Information Systems, and are--formulation of well--known ideas of Neural Networks and Many Agent Systems. All these approaches are discussed in this monograph. To make the exposition self--contained, underlying notions of Set Theory, Topology, and Deductive and Reductive Reasoning with emphasis on Rough and Fuzzy Set Theories along with a thorough exposition of Mereology both in Lesniewski and Whitehead--Leonard--Goodman--Clarke versions are discussed at length. It is hoped that the monograph offers researchers in various areas of Artificial Intelligence a new tool to deal with analysis of relations among concepts.
Approximation and Complexity in Numerical Optimization: Continuous and Discrete Problems (Nonconvex Optimization and Its Applications #42)
by Panos M. PardalosThere has been much recent progress in approximation algorithms for nonconvex continuous and discrete problems from both a theoretical and a practical perspective. In discrete (or combinatorial) optimization many approaches have been developed recently that link the discrete universe to the continuous universe through geomet ric, analytic, and algebraic techniques. Such techniques include global optimization formulations, semidefinite programming, and spectral theory. As a result new ap proximate algorithms have been discovered and many new computational approaches have been developed. Similarly, for many continuous nonconvex optimization prob lems, new approximate algorithms have been developed based on semidefinite pro gramming and new randomization techniques. On the other hand, computational complexity, originating from the interactions between computer science and numeri cal optimization, is one of the major theories that have revolutionized the approach to solving optimization problems and to analyzing their intrinsic difficulty. The main focus of complexity is the study of whether existing algorithms are efficient for the solution of problems, and which problems are likely to be tractable. The quest for developing efficient algorithms leads also to elegant general approaches for solving optimization problems, and reveals surprising connections among problems and their solutions. A conference on Approximation and Complexity in Numerical Optimization: Con tinuous and Discrete Problems was held during February 28 to March 2, 1999 at the Center for Applied Optimization of the University of Florida.
Approximation Methods in Science and Engineering
by Reza N. JazarApproximation Methods in Engineering and Science covers fundamental and advanced topics in three areas: Dimensional Analysis, Continued Fractions, and Stability Analysis of the Mathieu Differential Equation. Throughout the book, a strong emphasis is given to concepts and methods used in everyday calculations. Dimensional analysis is a crucial need for every engineer and scientist to be able to do experiments on scaled models and use the results in real world applications. Knowing that most nonlinear equations have no analytic solution, the power series solution is assumed to be the first approach to derive an approximate solution. However, this book will show the advantages of continued fractions and provides a systematic method to develop better approximate solutions in continued fractions. It also shows the importance of determining stability chart of the Mathieu equation and reviews and compares several approximate methods for that. The book provides the energy-rate method to study the stability of parametric differential equations that generates much better approximate solutions.

Approximation Theory: From Taylor Polynomials to Wavelets (Applied and Numerical Harmonic Analysis)
by Ole Christensen Khadija Laghrida ChristensenThis concisely written book gives an elementary introduction to a classical area of mathematics – approximation theory – in a way that naturally leads to the modern field of wavelets. The exposition, driven by ideas rather than technical details and proofs, demonstrates the dynamic nature of mathematics and the influence of classical disciplines on many areas of modern mathematics and applications. Featuring classical, illustrative examples and constructions, exercises, and a discussion of the role of wavelets to areas such as digital signal processing and data compression, the book is one of the few to describe wavelets in words rather than mathematical symbols.

Approximationstheorie: Tschebyscheffsche Approximation mit Anwendungen (Teubner Studienbücher Mathematik)
by Lothar Collatz Werner KrabsIn neuerer Zeit sind so viele Lehrbücher über Approximationstheorie erschienen, daß man nach der Berechtigung eines weiteren Buches fragen mag. Die Motivie rung ergab sich aus der Tatsache, daß sowohl in der Zeitschriftenliteratur über Approximationstheorie als auch in den meisten Lehrbüchern relativ wenig auf die Anwendungen eingegangen wird. Es scheint in der heutigen Zeit eine gewisse Diskrepanz zu bestehen zwischen manchen viel von Mathematikern bearbeiteten Gebieten und den Gebieten, deren mathematische Untersuchung von seiten der Anwendungen aus dringend erwünscht wäre. Die in physikalischen und technischen Fragestellungen auftretenden Approximationsprobleme sind, im Zug der fort schreitenden Entwicklung, so vielseitig und oft andersartig als in der bisher ge wöhnlich betrachteten Theorie und dabei zugleich häufig mathematisch sehr interessant und tiefliegend, so daß sich hier ein außerordentlich reiches Betäti gungsfeld für die mathematische Forschung ergibt. Sehr oft sind wir von Studen ten, Diplomanden, Doktoranden nach Themen aus der Approximationstheorie gefragt worden, die zugleich praktische Bedeutung haben, und da hierüber viel fach nicht genügend bekannt zu sein scheint, versucht dieses Büchlein, die Lücke zwischen Theorie und Anwendungen ein wenig aufzufüllen. Da bei den Anwen dungen von den verschiedenen Approximationsarten die Tschebyscheffsche Approximation, kurz T. A. , die anderen Typen an Bedeutung weit zu übertreffen scheint, befaßt sich das Buch vorwiegend mit der T. A. , und zwar sowohl mit der Theorie als auch mit den Anwendungen. Der Brücke zwischen bei den dienen auch verschiedene Übungsaufgaben am Schluß des Buches.
