This book was released on 2020-08-26 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spotlighting the field of Multidisciplinary Design Optimization (MDO), this book illustrates and implements state-of-the-art methodologies within the complex process of aerospace system design under uncertainties. The book provides approaches to integrating a multitude of components and constraints with the ultimate goal of reducing design cycles. Insights on a vast assortment of problems are provided, including discipline modeling, sensitivity analysis, uncertainty propagation, reliability analysis, and global multidisciplinary optimization. The extensive range of topics covered include areas of current open research. This Work is destined to become a fundamental reference for aerospace systems engineers, researchers, as well as for practitioners and engineers working in areas of optimization and uncertainty. Part I is largely comprised of fundamentals. Part II presents methodologies for single discipline problems with a review of existing uncertainty propagation, reliability analysis, and optimization techniques. Part III is dedicated to the uncertainty-based MDO and related issues. Part IV deals with three MDO related issues: the multifidelity, the multi-objective optimization and the mixed continuous/discrete optimization and Part V is devoted to test cases for aerospace vehicle design.
Book Synopsis Optimisation multicritère sous incertitudes by : Quentin Mercier
Download or read book Optimisation multicritère sous incertitudes written by Quentin Mercier and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse s'intéresse à l'optimisation multiobjectif sans contrainte lorsque les objectifs sont exprimés comme des espérances de fonctions aléatoires. L'aléa est modélisé par l'intermédiaire de variables aléatoires et on considère qu'il n'impacte pas les variables d'optimisation du problème. La thèse consiste à proposer un algorithme de descente qui permet l'obtention des solutions de Pareto du problème d'optimisation ainsi écrit. En utilisant des résultats d'analyse convexe, il est possible de construire un vecteur de descente commun à l'ensemble des objectifs du problème d'optimisation pour un tirage des variables aléatoires donné. Une suite itérative consistant à descendre dans la direction du vecteur de descente commun calculé au point courant et pour un tirage aléatoire unique et indépendant des variables aléatoires est alors construite. De cette manière, l'estimation coûteuse des espérances à chaque étape du processus d'optimisation n'est pas nécessaire. Il est possible de prouver les convergences en norme et presque sûre de cette suite vers les solutions de Pareto du problème d'optimisation en espérance et d'obtenir un résultat de vitesse de convergence lorsque la suite de pas de descente est bien choisie. Après avoir proposé diverses méthodes numériques d'amélioration de l'algorithme, un ensemble d'essais numériques est mené et les résultats de l'algorithme proposé sont comparés à ceux obtenus par deux autres algorithmes classiques de la littérature. Les résultats obtenus sont comparés par l'intermédiaire de mesures adaptées à l'optimisation multiobjectif et sont analysés par le biais de profils de performance. Des méthodes sont alors proposées pour prendre en compte deux types de contrainte et sont illustrées sur des problèmes d'optimisation de structures mécaniques. Une première méthode consiste à pénaliser les objectifs par l'intermédiaire de fonctions de pénalisation exacte lorsque la contrainte est décrite par une fonction déterministe. Pour les contraintes probabilistes, on propose de remplacer les contraintes par des objectifs supplémentaires, ces contraintes probabilistes étant alors reformulées comme des espérances de fonctions indicatrices, le problème étant résolu à l'aide de l'algorithme proposé dans la thèse sans avoir à estimer les probabilités des contraintes à chaque itération.

Book Synopsis Expected Utility Hypotheses and the Allais Paradox by : M. Allais
Download or read book Expected Utility Hypotheses and the Allais Paradox written by M. Allais and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: Utility theory or, value theory in general, is certainly the cornerstone of decision theory, game theory, microecon~mics, and all social and political theories which deal with public decisions. Recently the American School of utility, founded by von N eumann Morgenstern, encountered a far-going criticism by the French School of utility represented by its founder Allais. The whole basis of the theory of decisions involving risk has been shaken and put into question. Consequently, basic research in the fundamentals of utility and value theory evolved into a crisis. Like any crisis in basic research, and this one was not an exception, it was very fruitful. One may simply say: Allais versus von Neumann-Morgenstern, or the French School of utility versus the American School, became one of the battlefields of scientific development which proved to be a most creative source of new advances and new developments in all those sciences which are based on evaluation of utilities.

Book Synopsis Integrated Forest Biorefineries by : Lew Christopher
Download or read book Integrated Forest Biorefineries written by Lew Christopher and published by Royal Society of Chemistry. This book was released on 2012-09-30 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference book describes how bioprocessing and biotechnology could enhance the value extracted from wood-based lignocellulosic fiber by employing both biochemical and thermochemical conversion processes. It documents recent accomplishments and suggests future prospects for research and development of integrated forest biorefineries (IFBR) as the path forward for the pulp, paper and other fiber-processing industries. This is the only book to cover this area of high economic, social, and environmental importance. It is aimed at industrialists and academics from diverse science and engineering backgrounds including chemical and biotechnology companies, governmental and professional bodies, and scholarly societies. The Editor and contributors are internationally recognized scientists and many are leaders in their respective fields. The book starts with an introductory overview of the current state of biorefining and a justification for future developments. The next four chapters deal with social, economic and environmental issues related to regulations, biomass production and supply, process modelling, and life cycle analysis. Subsequent chapters focus on the extraction of biochemicals from biomass and their potential utilization to add value to the IFBR prior to pulping. The book then presents, compares and evaluates two types of forest biorefineries based on kraft and organosolv pulping. Finally, the book assess the potential of waste biomass and streams, such paper mill sludge and black liquor, to serve as feedstock for biofuel production and value-added biomaterials through both the biochemical and thermochemical routes of biomass bioprocessing. The economics of the described IFBR processes and products, and their environmental impact, is a major focus in most of the chapters. Practical examples are presented where relevant and applicable.

Book Synopsis Inequality Reexamined by : Amartya Sen
Download or read book Inequality Reexamined written by Amartya Sen and published by Harvard University Press. This book was released on 1995-03-15 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The noted economist and philosopher Amartya Sen argues that the dictum “all people are created equal” serves largely to deflect attention from the fact that we differ in age, gender, talents, and physical abilities as well as in material advantages and social background. He argues for concentrating on higher and more basic values: individual capabilities and freedom to achieve objectives. By concentrating on the equity and efficiency of social arrangements in promoting freedoms and capabilities of individuals, Sen adds an important new angle to arguments about such vital issues as gender inequalities, welfare policies, affirmative action, and public provision of health care and education.

Book Synopsis Nonlinear Multiobjective Optimization by : Kaisa Miettinen
Download or read book Nonlinear Multiobjective Optimization written by Kaisa Miettinen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Problems with multiple objectives and criteria are generally known as multiple criteria optimization or multiple criteria decision-making (MCDM) problems. So far, these types of problems have typically been modelled and solved by means of linear programming. However, many real-life phenomena are of a nonlinear nature, which is why we need tools for nonlinear programming capable of handling several conflicting or incommensurable objectives. In this case, methods of traditional single objective optimization and linear programming are not enough; we need new ways of thinking, new concepts, and new methods - nonlinear multiobjective optimization. Nonlinear Multiobjective Optimization provides an extensive, up-to-date, self-contained and consistent survey, review of the literature and of the state of the art on nonlinear (deterministic) multiobjective optimization, its methods, its theory and its background. The amount of literature on multiobjective optimization is immense. The treatment in this book is based on approximately 1500 publications in English printed mainly after the year 1980. Problems related to real-life applications often contain irregularities and nonsmoothnesses. The treatment of nondifferentiable multiobjective optimization in the literature is rather rare. For this reason, this book contains material about the possibilities, background, theory and methods of nondifferentiable multiobjective optimization as well. This book is intended for both researchers and students in the areas of (applied) mathematics, engineering, economics, operations research and management science; it is meant for both professionals and practitioners in many different fields of application. The intention has been to provide a consistent summary that may help in selecting an appropriate method for the problem to be solved. It is hoped the extensive bibliography will be of value to researchers.

Book Synopsis The Maltreatment of Children by : S.M. Smith
Download or read book The Maltreatment of Children written by S.M. Smith and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The maltreatment of children is an issue that has always been with us and civilized societies provide a range of services both social and medical to care for the children and families afflicted. In recent years, greater attention has been drawn to the medical aspects by competent authorities in the fields of forensic medicine, forensic psychiatry, epidemiological psychiatry, child psychiatry and family psychiatry; as well as the social aspects by those child welfare and child care agencies who have the difficult and distasteful task of removing children, with the help of the courts, from parents who can abuse them and are not able to care for them adequately. A multitude of social agencies, whose range of ac tivities involve both the care and, where possible, the social betterment of afflicted families are now involved. Not least in importance is an increase in our global knowledge to help in the prevention or better treatment of these problems. This means more informa tion on familial and genetic factors in human central nervous system develop ment in its broadest sense. This would include how the central nervous system originates, mediates and controls the build up, speed of development and im pulsive release, mastery and direction of aggressive drives and impulses. Very little is so far known about these factors.
