    • 1st Edition
    • Volume 11
    • Charles George Broyden + 1 more
    • English
    The first four chapters of this book give a comprehensive and unified theory of the Krylov methods. Many of these are shown to be particular examples ofthe block conjugate-gradient algorithm and it is this observation thatpermits the unification of the theory. The two major sub-classes of thosemethods, the Lanczos and the Hestenes-Stiefel, are developed in parallel asnatural generalisations of the Orthodir (GCR) and Orthomin algorithms. Theseare themselves based on Arnoldi's algorithm and a generalised Gram-Schmidtalgorith... and their properties, in particular their stability properties,are determined by the two matrices that define the block conjugate-gradiental... These are the matrix of coefficients and the preconditioningmatri... Chapter 5 the"transpose-free" algorithms based on the conjugate-gradient squared algorithm are presented while Chapter 6 examines the various ways in which the QMR technique has been exploited. Look-ahead methods and general block methods are dealt with in Chapters 7 and 8 while Chapter 9 is devoted to error analysis of two basic algorithms.In Chapter 10 the results of numerical testing of the more important algorithms in their basic forms (i.e. without look-ahead or preconditioning) are presented and these are related to the structure of the algorithms and the general theory. Graphs illustrating the performances of various algorithm/problem combinations are given via a CD-ROM.Chapter 11, by far the longest, gives a survey of preconditioning techniques. These range from the old idea of polynomial preconditioning via SOR and ILU preconditioning to methods like SpAI, AInv and the multigrid methods that were developed specifically for use with parallel computers. Chapter 12 is devoted to dual algorithms like Orthores and the reverse algorithms of Hegedus. Finally certain ancillary matters like reduction to Hessenberg form, Chebychev polynomials and the companion matrix are described in a series of appendices.

  • Failure Criteria in Fibre-Reinforced-Polymer Composites

    • 1st Edition
    • M. Hinton + 2 more
    • English
    Fiber reinforced polymer composites are an extremely broad and versatile class of material.Their high strength coupled with lightweight leads to their use wherever structural efficiency is at a premium. Applications can be found in aircraft, process plants, sporting goods and military equipment. However they are heterogeneous in construction and antisotropic, which makes making strength prediction extremely difficult especially compared to that of a metal. This book brings together the results of a 12year worldwide failure exercise encompassing 19 theories in a single volume. Each contributor describes their own theory and employs it to solve 14 challenging problems. The accuracy of predictions and the performance of the theories are assessed and recommendations made on the uses of the theories in engineering design.All the necessary information is provided for the methodology to be readily employed for validating and benchmarking new theories as they emerge.

  • Introduction to the Modelling of Marine Ecosystems

    (with MATLAB programs on accompanying CD-ROM)
    • 1st Edition
    • Volume 72
    • W. Fennel + 1 more
    • English
    Modelling of marine ecosystems is a rapidly developing branch of interdisciplinary oceanographic research. Introduction to the Modelling of Marine Ecosystems is the first consistent and comprehensive introduction to the development of models of marine ecosystems. It begins with simple first steps of modelling and develops more and more complex models. This step-by-step approach to increasing the complexity of the models is intended to allow students of biological oceanography and interested scientists with only limited experience in mathematical modelling to explore the theoretical framework and familiarize oneself with the methods. The book describes how biological model components can be integrated into three dimensional circulation models and how such models can be used for 'numerical experiments'.The book illustrates the mathematical aspects of modelling and gives application examples. The tutorial aspect of the book is supported by a set of MATLAB programs, which are provided on an accompanying CD-Rom and which can be used to reproduce many of the results presented in the book.Also available in paperback, ISBN 0-444-51704-9

  • Transportation Labor Issues and Regulatory Reform

    • 1st Edition
    • Volume 10
    • James H Peoples + 1 more
    • English
    Regulatory reform in the late 1970s and early 1980s vastly transformed the labor market for transportation workers. Most research in this area focuses on the effect of deregulation on the earnings of nonmanagement company workers in airline, trucking and rail. Deregulation of transportation industries, though, has had a broader effect on workers. For instance, deregulation also influences workers’ hours worked per week, working conditions, worker safety, and a host of other labor issues. Deregulation might also influence the earnings of managers and self-employed workers in transportation industries. Examining these issues is valuable because such analysis provides a more complete assessment of labor market changes following the shift to a more market oriented business environment.Transpor... Labor Issues and Regulatory Reform adds to the debate on deregulation’s influence on transportation labor markets by presenting empirical evidence on an array of labor market outcomes in transportation industries. Contributions to this volume are categorized by their analysis on worker safety, working conditions and employment opportunities, and by their analysis on managerial and self-employed earnings

  • The Institutional Economics of Market-Based Climate Policy

    • 1st Edition
    • Volume 7
    • E. Woerdman
    • English
    The objective of this book is to analyze the institutional barriers to implementing market-based climate policy, as well as to provide some opportunities to overcome them. The approach is that of institutional economics, with special emphasis on political transaction costs and path dependence.Instead of rejecting the neoclassical approach, this book uses it where fruitful and shows when and why it is necessary to employ a new or neo-institutionalist approach. The result is that equity is considered next to efficiency, that the evolution and possible lock-in of both formal and informal climate institutions are studied, and that attention is paid to the politics and law of economic instruments for climate policy, including some new empirical analyses.The research topics of this book include the set-up costs of a permit trading system, the risk that credit trading becomes locked-in, the potential legal problem of grandfathering in terms of actional subsidies under WTO law or state aid under EC law, and the changing attitudes of various European officials towards restricting the use of the Kyoto Mechanisms.

  • Reliable Methods for Computer Simulation

    Error Control and Posteriori Estimates
    • 1st Edition
    • Volume 33
    • Pekka Neittaanmäki + 1 more
    • English
    Recent decades have seen a very rapid success in developing numerical methods based on explicit control over approximation errors. It may be said that nowadays a new direction is forming in numerical analysis, the main goal of which is to develop methods ofreliable computations. In general, a reliable numerical method must solve two basic problems: (a) generate a sequence of approximations that converges to a solution and (b) verify the accuracy of these approximations. A computer code for such a method must consist of two respective blocks: solver and checker.In this book, we are chiefly concerned with the problem (b) and try to present the main approaches developed for a posteriori error estimation in various problems.The authors try to retain a rigorous mathematical style, however, proofs are constructive whenever possible and additional mathematical knowledge is presented when necessary. The book contains a number of new mathematical results and lists a posteriori error estimation methods that have been developed in the very recent time.
