Available in PDF, EPUB and Kindle. Book excerpt: To solve a large system of linear equations, iterative methods can often be faster and more accurate than direct methods such as Gaussian elimination. A stationary iterative method can be derived from a splitting of the coefficient matrix as the difference of two matrices and generates a sequence of vectors that is expected to converge to the solution. Convergence depends on whether the spectral radius of the iteration matrix is within unity. Certain splittings generate different, well-known methods such as the Jacobi, Gauss-Seidel, and successive over-relaxation (SOR) iterative methods. Controlled over-relaxation (COR) is an extrapolated iterative method that is applicable to any splitting and its convergence depends on whether all the eigenvalues of the iteration matrix lie on one side of the vertical line x=1. This thesis presents several theorems on the convergence of COR. It is shown that for the optimal relaxation parameter COR converges at least as fast as the corresponding iterative method. Also, it is shown that for positive definite matrices, applying COR to the splitting of SOR will enlarge the interval on which the parameter for SOR may belong to. Bounds on the SOR parameter are derived. In addition to the study of well-known splittings, a theorem is presented that defines a class of splittings that is guaranteed convergent for COR. With a large sample of matrices the convergence of COR is compared to the corresponding Jacobi, Gauss-Seidel, and SOR methods. Additionally, matrix weighted extrapolated methods are considered and for a special case the optimal situation is studied.

Download or read book Photothermal Spectroscopy Methods for Chemical Analysis written by Stephen E. Bialkowski and published by John Wiley & Sons. This book was released on 1996-01-12 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique guide to the application and theory of photothermalspectroscopy. This book debunks the myth that photothermal spectroscopy is toocomplicated for practical application to chemical analysis, anddemonstrates the advantages this technique has over conventionalspectroscopy in facilitating extremely sensitive measurements ofoptical absorption in homogeneous media. The book covers thesubject from the ground up, lists all practical considerationsneeded to obtain accurate results, and provides a working knowledgeof the various methods in use--including photo acoustics andphotopyroelectric techniques. Bringing together a wealth of information that has been scatteredthroughout the professional literature, Photothermal SpectroscopyMethods for Chemical Analysis covers methods and information thatshould be known to every analytical chemist, including: * Descriptions of photothermal spectroscopy using a consistentmathematical language * Helpful examples from the literature of analytical applicationsand current research * Illustrations of all important points, consistent equations, andnumerous original figures * A discussion of laser technology and how it is used to obtainaccurate results from extremely small samples of a few molecules * Everything spectroscopists need to know to construct their ownapparatus and use it to conduct successful experiments * Tips on how to interpret experimental results effectively whenusing nonlinear processes and in many other situations inphotothermal spectroscopy * Considerations for further study of heterogeneous sampleanalysis * Unified nomenclature of the patchwork of terms used byresearchers in analytical and physical chemistry, physics, andoptical engineering * Equations that are derived with the aid of a symbolic languageprocessor to ensure correct results Photothermal spectroscopy has seen major advances since the adventof laser technology twenty-five years ago. It is now possible,using a laser's coherent and powerful output, to obtain extremelysensitive measurements of optical absorption that exceed those ofmass spectroscopy by two or three times, and produce accurateresults from only a few molecules. Focusing on samples in homogeneous media, this book provides aunique guide--incorporating theory and application--to allavailable photothermal spectroscopy techniques for chemical andmaterial analysis. It uses a systematic approach in itscomprehensive treatment of the theory, and covers all the necessarybackground material, from laser optics to fluid dynamics. This accessible text describes the various processes used to detectthermal perturbation of a sample, ranging from optical excitationto nonlinear processes, and covers all optical principles necessaryto understand photothermal spectroscopy. When dealing withhydrodynamic equations that govern energy transfer in the samplematrix, it provides an original impulse-response approach. Inaddition, the book explains how to construct the apparatus oneneeds to conduct successful photothermal experiments, sincecommercial equipment is not available as in conventionalspectrophotometry. Throughout, this book draws on information from a wide range offields, including analytical spectroscopy, measurement physics,physical optics, and chemical dynamics. Providing clearexplanations at every turn, the author demonstrates a completeunderstanding of the theory and applications as a firm basis forthe correct interpretation of experimental results. For analytical chemists, as well as for students at the graduatelevel, Photothermal Spectroscopy Methods for Chemical Analysis isan unmatched resource that develops a consistent mathematical basisfor signal description, consolidates previous theories, andprovides invaluable insight into laser technology.

Download or read book Constrained Optimization and Optimal Control for Partial Differential Equations written by Günter Leugering and published by Springer Science & Business Media. This book was released on 2012-01-03 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: This special volume focuses on optimization and control of processes governed by partial differential equations. The contributors are mostly participants of the DFG-priority program 1253: Optimization with PDE-constraints which is active since 2006. The book is organized in sections which cover almost the entire spectrum of modern research in this emerging field. Indeed, even though the field of optimal control and optimization for PDE-constrained problems has undergone a dramatic increase of interest during the last four decades, a full theory for nonlinear problems is still lacking. The contributions of this volume, some of which have the character of survey articles, therefore, aim at creating and developing further new ideas for optimization, control and corresponding numerical simulations of systems of possibly coupled nonlinear partial differential equations. The research conducted within this unique network of groups in more than fifteen German universities focuses on novel methods of optimization, control and identification for problems in infinite-dimensional spaces, shape and topology problems, model reduction and adaptivity, discretization concepts and important applications. Besides the theoretical interest, the most prominent question is about the effectiveness of model-based numerical optimization methods for PDEs versus a black-box approach that uses existing codes, often heuristic-based, for optimization.
