Download or read book BASIS OF THE FINITE ELEMENT METHOD written by BENITO MUÑOZ, Juan José and published by Editorial UNED. This book was released on 2023-10-04 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an introduction to the Finite Element Method (FEM) and is primarily aimed at students, engineers and scientists who already know structural calculation. It starts from the matrix reformulation of the direct stiffness method to understand the enormous potential of introducing the idea of the weak formulation for the approximation of strut structure problems. The correspondence of results between the initial classical formulation and that of the FEM when using linear shape functions and Hermite polynomials, makes it possible to approach its general formulation more easily as a procedure to obtain approximate solutions of differential equations in partial derivatives. It is essential now to introduce the idea of element, which allows, from the definition of a reduced number of base functions and through a simple combination process, to approximate its real behavior and, through superposition, that of the structure.

Available in PDF, EPUB and Kindle. Book excerpt: This text is designed for those who already know structural calculation. It starts with the simple exercise of reformulating the direct stiffness method using matrices. The aim is to allow the student to understand the enormous power and generality of the weak formulation for the approximation of strut structure problems by using a formulation which is easy to understand. The correspondence of results of the initial classical formulation with those of the FEM when using linear shape functions and Hermite polynomials allows us to tackle the general formulation of the fundamental concepts of the method more easily. Once the method and the details of its general formulation are understood (although only through its application in a specific structural type), the FEM is presented in a general way, as a procedure for obtaining approximated solutions for partial differential equations. The approaches to field problems and to linear elasticity problems are presented as examples. The method has been now clearly presented and therefore, the selection of the type of element, with the generation of interpolation functions of higher degree and their systematization in element families, can be studied in greater depth. This part finishes with the introduction of the idea of isoparametric transformation that, together with numerical integration, explains the stage of development reached by the method. Finally, the subject relative to plates is dealt with, looking at their specific use as structural elements, and trying to show the difficulty of satisfying the continuity between elements in thin plates, and the shear locking solution in thick plates amongst other things
Download or read book Gender Disparities in Africa s Labor Market written by Jorge Saba Arbache and published by World Bank Publications. This book was released on 2010-08-05 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Women's earnings are a fraction of male's earnings in several African countries. It is tempting to conclude that this wage gap is a sign of discrimination against women in the labor market. Yet this book uses new datasets to show that the gap is not simply the result of discrimination in the labor markets, but rather the result of multiple factors, including access to education and credit, cultural values and household duties, and, above all, labor market conditions. It shows that gender disparities grow when economies are not functioning well and labor markets are tiny. More than the effect of discrimination, it seems that job rationing causes those with better human capital and those with more power in the household usually the men to take the few jobs that are available. It is hardly surprising, then, that in a region where only a fraction of the labor force finds jobs in the formal sector, gender disparities in earnings are so high. The book further documents that firm-level and sector characteristics are additional powerful factors in explaining the gender disparities in the labor market. As the causes are not simple, neither are the solutions; multifaceted strategies are needed. By providing environments that support economic growth and, more importantly, job creation, as well as by promoting equal access for women to education and rethinking the attitudes that limit what women may achieve, governments in the region will substantially improve the well-being of all their peoples. 'Gender Disparities in Africa's Labor Market' helps to fill the knowledge gap and identify the links between gender disparities and poverty reduction. The work was implemented in collaboration with a range of poverty and labor market studies to maximize its usefulness for policy dialogue in specific countries. This book will be of interest to policy makers, students, academics, gender experts, and all those interested in gender issues and development.

Download or read book Environmental Social Accounting Matrices written by Pablo Martínez de Anguita and published by Routledge. This book was released on 2010-04-05 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book Professors Pablo Martínez de Anguita and John E. Wagner put two disciplines together, regional and ecological economics, presenting a way to understand ecological economic concerns from a regional perspective, and providing a mathematical tool to measure their interrelationships. This book offers different regional economic models that explicitly include the role of the natural resources and pollutants in economic regions through the use of Social Accounting Matrixes and Input-output models. The main objective of this book is to explore Input-output and Social Accounting Matrix (SAM) models by expanding the accounts to include natural resources and the environment. The proposed models in this book incorporate the forest and other natural resources and pollutants as a component in a larger model of how the economy and environment of larger areas interact. This book will be of interests to postgraduates, researchers and scientists in the fields of regional, resource, environmental, or ecological economics.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers some important topics in the construction of computable general equilibrium (CGE) models and examines use of these models for the analysis of economic policies, their properties, and their implications. Readers will find explanation and discussion of the theoretical structure and practical application of several model typologies, including dynamic, stochastic, micro-macro, and simulation models, as well as different closure rules and policy experiments. The presentation of applications to various country and problem-specific case studies serves to provide an informed and clearly articulated summary of the state of the art and the most important methodological advancements in the field of policy modeling within the framework of general equilibrium analysis. The book is an outcome of a recent workshop of the Italian Development Economists Association attended by a group of leading practitioners involved in the generation of CGE models and research on modeling the economy and policy making. It will be of interest to researchers, professional economists, graduate students, and knowledgeable policy makers.

Download or read book New Tools of Economic Dynamics written by Jacek Leskow and published by Springer Science & Business Media. This book was released on 2006-05-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Tools of Economic Dynamics gives an introduction and overview of recently developed methods and tools, most of them developed outside economics, to deal with the qualitative analysis of economic dynamics. It reports the results of a three-year research project by a European and Latin American network on the intersection of economics with mathematical, statistical, and computational methods and techniques. Focusing upon the evolution and manifold structure of complex dynamic phenomena, the book reviews and shows applications of a variety of tools, such as symbolic and coded dynamics, interacting agents models, microsimulation in econometrics, large-scale system analysis, and dynamical systems theory. It shows the potential of a comprehensive analysis of growth, fluctuations, and structural change along the lines indicated by pioneers like Harrod, Haavelmo, Hicks, Goodwin, Morishima, and it highlights the explanatory power of the qualitative approach they initiated.
