Book Synopsis La Modélisation multidimensionnelle des écoulements dans les moteurs by : Thierry Baritaud
Download or read book La Modélisation multidimensionnelle des écoulements dans les moteurs written by Thierry Baritaud and published by Editions TECHNIP. This book was released on 1999 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an increasingly challenging commercial environment, and the need imposed by safety principles to reduce both fuel consumption and pollutant emissions, the development of new engines can now benefit from the advances of computational fluid dynamics. Engine CFD is a most challenging simulation problem. This is caused by the spread of time and space scales, the excursion amplitude of most parameters, the high quasi-cyclic unstationarity of engine flows, the importance of minor geometry details, the number of physical and chemical processes including turbulent combustion and multi-phase flows to model. However, engine CFD has now reached a state where it has become a widely used tool, not only for engine understanding, but also increasingly for engine design. Undoubtedly, laser diagnostics in optical access engines have also brought significant help.Contents: 1. State of the art of multi-dimensional modeling of engine reacting flows. 2.

Book Synopsis Multidimensional Screening by : Suren Basov
Download or read book Multidimensional Screening written by Suren Basov and published by Springer Science & Business Media. This book was released on 2005-01-11 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many industries the tariffs are not strictly proportional to the quantity purchased, i. e, they are nonlinear. Examples of nonlinear tariffs include railroad and electricity schedules and rental rates for durable goods and space. The major justification for the nonlinear pricing is the existence of private information on the side of consumers. In the early papers on the subject, private information was captured either by assuming a finite number of types (e. g. Adams and Yellen, 1976) or by a unidimensional continuum of types (Mussa and Rosen, 1978). Economics of the unidimen sional problems is by now well understood. The unidimensional models, however, do not cover all the situations of practical interest. Indeed, often the nonlinear tariffs specify the payment as a function of a variety of characteristics. For example, railroad tariffs spec ify charges based on weight, volume, and distance of each shipment. Dif ferent customers may value each of these characteristics differently, hence the customer's type will not in general be captured by a unidimensional characteristic and a problem of multidimensional screening arises. In such models the consumer's private information (her type) is captured by an m—dimensional vector, while the good produced by the monopolist has n quality dimensions.

Book Synopsis The Qualimetrics Approach by : Henri Savall
Download or read book The Qualimetrics Approach written by Henri Savall and published by IAP. This book was released on 2011-06-01 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this work emerged from Savall’s belief that there is a doubleloop interaction between social and economic factors in organizations, between behaviors and structures, and between the quality of life in organizations and their economic performance. When managers underestimate this dynamic interaction, the resulting tension ultimately manifests in lowered performance and increased costs, what he refers to as the “hidden costs” of organizational life. Only by delving into the depths of these organizational dynamics can we hope to fully understand – and create the basis for improving – organizational performance. The Qualimetrics Approach presents a different and challenging way of thinking about analyzing organizations, one that draws together quantitative information, financial analysis and qualitative insights into organizational dynamics. As Savall and Zardet argue, to gain a true understanding of what is happening in organizations, intervener-researchers must focus on all three perspectives, as ignoring any one of them will lead to incomplete understandings. Their approach underscores the importance of using qualitative data to validate quantitative depictions (“the numbers”) of organizational performance in understanding the construction of financial statements. The strength of Savall and Zardet’s approach is that it pushes us to go deeper, to fully understand the narratives underlying the numbers and the social construction of our financial assessments.

Book Synopsis Finite Volumes for Complex Applications VII-Methods and Theoretical Aspects by : Jürgen Fuhrmann
Download or read book Finite Volumes for Complex Applications VII-Methods and Theoretical Aspects written by Jürgen Fuhrmann and published by Springer. This book was released on 2014-05-12 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first volume of the proceedings of the 7th conference on "Finite Volumes for Complex Applications" (Berlin, June 2014) covers topics that include convergence and stability analysis, as well as investigations of these methods from the point of view of compatibility with physical principles. It collects together the focused invited papers, as well as the reviewed contributions from internationally leading researchers in the field of analysis of finite volume and related methods. Altogether, a rather comprehensive overview is given of the state of the art in the field. The finite volume method in its various forms is a space discretization technique for partial differential equations based on the fundamental physical principle of conservation. Recent decades have brought significant success in the theoretical understanding of the method. Many finite volume methods preserve further qualitative or asymptotic properties, including maximum principles, dissipativity, monotone decay of free energy, and asymptotic stability. Due to these properties, finite volume methods belong to the wider class of compatible discretization methods, which preserve qualitative properties of continuous problems at the discrete level. This structural approach to the discretization of partial differential equations becomes particularly important for multiphysics and multiscale applications. Researchers, PhD and masters level students in numerical analysis, scientific computing and related fields such as partial differential equations will find this volume useful, as will engineers working in numerical modeling and simulations.

Book Synopsis Poverty and Social Exclusion around the Mediterranean Sea by : Valerie Berenger
Download or read book Poverty and Social Exclusion around the Mediterranean Sea written by Valerie Berenger and published by Springer Science & Business Media. This book was released on 2012-11-15 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The events taking place in several of South Mediterranean countries since December 2010 show that multiple deprivations may be powerful drivers of political instability. Though improvements of the living conditions have been regularly principal demands along with civil and political liberties in the demonstrations, one of the main striking facts about this so-called “Arab Spring” is that poverty had not been given the same emphasis in southern Mediterranean countries during the last decades as in other areas of the developing and emerging world. Although the growing recognition that poverty is a multidimensional concept, studies of poverty in South Mediterranean countries have often been dominated by a monetary approach. However, there is a growing evidence that it is suitable to go beyond the money-metric measures of poverty and to supplement its results with other approaches that adopt a broader definition of well- being. Though poverty is only one of many causes of this “Arab Spring,” we argue that it is a key feature to understand these historic events and that it is necessary to draw a detailed picture of poverty and social exclusion for each one of these countries. Moreover, if the Union for the Mediterranean succeeds in fostering economic cooperation within the Mediterranean area, the focus on the population’s well-being of its southern members will deserve scrutiny in the next few years to understand the forces that will drive the Euro-Mediterranean relationships, in particular for migration issues. This book brings together recent advances on the measurement of poverty with empirical applications on South-Mediterranean countries. It introduces new tools for analyzing poverty and shows that the linkages between income and well-being are not straightforward and hinge on many determinants. It shows that the efficiency of poverty reducing policies should also be assessed on the basis of the satisfaction of non-income needs like health, education or participation in social life.
