The General Theory of Homogenization: A Personalized Introduction by Luc Tartar
English | PDF (True) | 2010 | 466 Pages | ISBN : 3642051944 | 5.2 MB
Homogenization is not about periodicity, or Gamma-convergence, but about understanding which effective equations to use at macroscopic level, knowing which partial differential equations govern mesoscopic levels, without using probabilities (which destroy physical reality); instead, one uses various topologies of weak type, the G-convergence of Sergio Spagnolo, the H-convergence of François Murat and the author, and some responsible for the appearance of nonlocal effects, which many theories in continuum mechanics or physics guessed wrongly.

For a better understanding of 20th century science, new mathematical tools must be introduced, like the author's H-measures, variants by Patrick Gérard, and others yet to be discovered.

Turbopumps and Pumping Systems by S. Ahmad Nourbakhsh (Prof.Dr.Ir), Baron Andre Jaumotte (Prof.Dr.Ir), Charles Hirsch (Prof.Dr.Ir), Hamideh B. Parizi (PhD.,P.Eng.em)
English | PDF (True) | 2008 | 201 Pages | ISBN : 3540251294 | 56.5 MB
Pumps are one of the mechanical devices that are widely used in many industries throughout the world. Turbopumps which are common types of pumps are used mainly for transporting water in agricultural units, industrial processes, cooling and heating systems, and power plants. But their application is not limited only for h- dling water. Turbopumps can be used for transporting oil products in oil and gas industries and re neries, as well as byproductsin pulp and paper industry, food and beverage in food industry, and contaminated water in sewage systems. Because of the versatility of pump usage, the numberof turbopumpsin operation worldwide is very large and as a result the total energy consumption of these units can be considerable. To reduce the energy consumption by turbopumps, it is imp- tant to increase the ef ciency of the pumps, as well as the system they are working in. The pump manufacturing companies and design engineers are constantly trying to improve the performances of pumps by designing more ef cient pumps and by using the latest technologies available in terms of design software, new developed materials, and state of the art manufacturing tools. Today, computational uid - namics and sophisticated design software tools help designers to optimize the uid ow inside the pumps and to design different pump elements with better hydraulic ef ciencies. However, the operation of turbopumps can be optimized a well by effectively using proper pumps and designing ef cient piping systems.

Urbicide: The Death of the City by Fernando Carrión Mena, Paulina Cepeda Pico
English | PDF,EPUB | 2023 | 930 Pages | ISBN : 3031253035 | 130.4 MB
This book uses the reflection of academics specialized in the urban area of ​​Latin America, Europe and the United States, to initiate a comparative debate of the different dynamics in which Urbicidio expresses itself. The field or focal point of analysis that this publication approaches is the city, but under a new critical perspective of inverse methodology to that has been traditional used. It is about understanding the structural causes of self-destruction to finally thinking better and then going from pessimism to optimism.

It is a deep look at the city from an unconventional entrance, because it is about knowing and analyzing what the city loses by the action deployed by own urbanites, both in the field of its production and in the field of its consumption. This suppose that the city does not have an ascending linear sequential evolution in its development but neither in each of its parts in the improvement process, showing the face that commonly not seen but others live.
The category used for this purpose is that of Urbicidio or the death of the city, which contributes theoretically and methodologically to the knowledge of the city, as well as to the design of urban policies that neutralize it. In addition, it is worth mentioning that the book has an inclusive view of the authors. For this reason, gender parity, territorial representation and the presence of age groups have been sought.

Variational Methods in Theoretical Mechanics by John T. Oden , Junuthula N. Reddy
English | PDF | 1983 | 319 Pages | ISBN : 3540119175 | 25.1 MB
This is a textbook written for use in a graduate-level course for students of mechanics and engineering science. It is designed to cover the essential features of modern variational methods and to demonstrate how a number of basic mathematical concepts can be used to produce a unified theory of variational mechanics. As prerequisite to using this text, we assume that the student is equipped with an introductory course in functional analysis at a level roughly equal to that covered, for example, in Kolmogorov and Fomin (Functional Analysis, Vol. I, Graylock, Rochester, 1957) and possibly a graduate-level course in continuum mechanics. Numerous references to supplementary material are listed throughout the book. We are indebted to Professor Jim Douglas of the University of Chicago, who read an earlier version of the manuscript and whose detailed suggestions were extremely helpful in preparing the final draft. We also gratefully acknowedge that much of our own research work on va ri at i ona 1 theory was supported by the U. S. Ai r Force Offi ce of Scientific Research. We are indebted to Mr. Ming-Goei Sheu for help in proofreading. Finally, we wish to express thanks to Mrs. Marilyn Gude for her excellent and painstaking job of typing the manuscript. This revised edition contains only minor revisions of the first. Some misprints and errors have been corrected, and some sections were deleted, which were felt to be out of date.

Variational Models and Methods in Solid and Fluid Mechanics by Francesco dell'Isola, Sergey Gavrilyuk
English | PDF (True) | 2011 | 363 Pages | ISBN : 3709109825 | 3.4 MB
F. dell'Isola, L. Placidi: Variational principles are a powerful tool also for formulating field theories. - F. dell'Isola, P. Seppecher, A. Madeo: Beyond Euler-Cauchy Continua. The structure of contact actions in N-th gradient generalized continua: a generalization of the Cauchy tetrahedron argument. - B. Bourdin, G.A. Francfort: Fracture. - S. Gavrilyuk: Multiphase flow modeling via Hamilton's principle. - V. L. Berdichevsky: Introduction to stochastic variational problems. - A. Carcaterra: New concepts in damping generation and control: theoretical formulation and industrial applications. - F. dell'Isola, P. Seppecher, A. Madeo: Fluid shock wave generation at solid-material discontinuity surfaces in porous media.

Variational methods give an efficient and elegant way to formulate and solve mathematical problems that are of interest to scientists and engineers. In this book three fundamental aspects of the variational formulation of mechanics will be presented: physical, mathematical and applicative ones.
The first aspect concerns the investigation of the nature of real physical problems with the aim of finding the best variational formulation suitable to those problems. The second aspect is the study of the well-posedeness of those mathematical problems which need to be solved in order to draw previsions from the formulated models. And the third aspect is related to the direct application of variational analysis to solve real engineering problems.

Variational Principles of Continuum Mechanics: I. Fundamentals by Victor Berdichevsky
English | PDF | 2009 | 589 Pages | ISBN : 3540884661 | 6.1 MB
This is a concise and understandable book about variational principles of continuum mechanics. The book is accessible to applied mathematicians, physicists and engineers who have an interest in continuum mechanics.

There are about 500 books on variational principles. They are concerned mostly with the mathematical aspects of the topic. The major goal of this book is to discuss the physical origin of the variational principles and the intrinsic interrelations between them. For example, the Gibbs principles appear not as the rst principles of the theory of thermodynamic equilibrium but as a consequence of the Einstein formula for thermodynamic uctuations. The mathematical issues are considered as long as they shed light on the physical outcomes and/or provide a useful technique for direct study of variational problems. Thebookisacompletelyrewrittenversionoftheauthor'sm onographVariational Principles of Continuum Mechanics which appeared in Russian in 1983. I have been postponing the English translation because I wished to include the variational pr- ciples of irreversible processes in the new edition. Reaching an understanding of this subject took longer than I expected. In its nal form, this book covers all aspects of the story. The part concerned with irreversible processes is tiny, but it determines the accents put on all the results presented. The other new issues included in the book are: entropy of microstructure, variational principles of vortex line dynamics, va- ational principles and integration in functional spaces, some stochastic variational problems, variational principle for probability densities of local elds in composites with random structure, variational theory of turbulence; these topics have not been covered previously in monographic literature.

Variational Principles of Continuum Mechanics: II. Applications by Victor Berdichevsky
English | PDF | 2009 | 432 Pages | ISBN : 3540884688 | 4.3 MB
The book reviews the two features of the variational approach: its use as a universal tool to describe physical phenomena and as a source for qualitative and quantitative methods of studying particular problems.

Berdichevsky's work differs from other books on the subject in focusing mostly on the physical origin of variational principles as well as establishing their interrelations. For example, the Gibbs principles appear as a consequence of the Einstein formula for thermodynamic fluctuations rather than as the first principles of the theory of thermodynamic equilibrium. Mathematical issues are considered as long as they shed light on the physical outcomes and/or provide a useful technique for the direct study of variational problems. In addition, a thorough account of variational principles discovered in various branches of continuum mechanics is given.
This book, the second volume, describes how the variational approach can be applied to constructing models of continuum media, such as the theory of elastic plates; shells and beams; shallow water theory; heterogeneous mixtures; granular materials; and turbulence. It goes on to apply the variational approach to asymptotical analysis of problems with small parameters, such as the derivation of the theory of elastic plates, shells and beams from three-dimensional elasticity theory; and the basics of homogenization theory. A theory of stochastic variational problems is considered in detail too, along with applications to the homogenization of continua with random microstructures.
