This book was released on 2012-07-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: En mécanique des fluides, les mesures non intrusives sont fondamentales pour améliorer la connaissance du comportement des écoulements. Les cartes de vitesse, de température et de concentration, ainsi que la granulométrie des particules dans les écoulements diphasiques, permettent de mieux appréhender les phénomènes physiques, pour ensuite valider les codes de calculs. Les mesures de vitesse (ainsi que de températures et de concentrations de différentes espèces) par des techniques spectroscopiques reposant sur la diffusion des molécules sont bien adaptées à la caractérisation des écoulements rapides et réactifs , elles reposent sur la fluorescence induite par laser, la diffusion Raman Anti-Stokes cohérente ou l'emploi de diodes laser accordables. Dans les écoulements diphasiques, la détermination de la granulométrie des particules par des moyens optiques, ainsi que les principes de diffusion de la lumière sont détaillés. Pour chaque technique, les principes de base sont décrits, ainsi que les dispositifs optiques et de traitements des signaux. Les principales mesures de sécurité pour utiliser des sources laser intenses sont rappelées.

This book was released on 2018-03-24 with total page 799 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of 2 special volumes dedicated to the memory of Gérard Maugin. Including 40 papers that reflect his vast field of scientific activity, the contributions discuss non-standard methods (generalized model) to demonstrate the wide range of subjects that were covered by this exceptional scientific leader. The topics range from micromechanical basics to engineering applications, focusing on new models and applications of well-known models to new problems. They include micro–macro aspects, computational endeavors, options for identifying constitutive equations, and old problems with incorrect or non-satisfying solutions based on the classical continua assumptions.

Download or read book Propagation of Sound in Porous Media written by J.F. Allard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has grown out of the research activities of the author in the fields of sound propagation in porous media and modelling of acoustic materials. It is assumed that the reader has a background of advanced calculus, including an introduction to differential equations, complex variables and matrix algebra. A prior exposure to theory of elasticity would be advantageous. Chapters 1-3 deal with sound propagation of plane waves in solids and fluids, and the topics of acoustic impedance and reflection coefficient are given a large emphasis. The topic of flow resistivity is presented in Chapter 2. Chapter 4 deals with sound propagation in porous materials having cylindrical pores. The topics of effective density, and of tortuosity, are presented. The thermal exchanges between the frame and the fluid, and the behaviour of the bulk modulus of the fluid, are described in this simple context. Chapter 5 is concerned with sound propagation in other porous materials, and the recent notions of characteristic dimensions, which describe thermal exchanges and the viscous forces at high frequencies, are introduced. In Chapter 6, the case of porous media having an elastic frame is considered in the context of Biot theory, where new topics described in Chapter 5 have been included.
Download or read book Signal Processing for Geologists Geophysicists written by Jean-Luc Mari and published by Institut Francais Du Petrole P. This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasingly sophisticated techniques are available for obtaining seismic sections that give an accurate description of subsurface heterogeneities. These techniques continue to benefit from the progress made in research by signal processing specialists. The aim of this book is to familiarize geologists and geophysicists with the basic concepts of signal processing used in seismic surveys. It shows the value of using a combination of tools to solve a given problem. Many of the examples in this book come from the latest research. Its goal is to improve understanding of the most common signal processing algorithms and to suggest a methodology for testing them. Sometimes, modeling with simple, well-known functions is a very useful way to understand the behavior of a transformation. In this way, we seek to provide the specialist with a critical approach for handling these algorithms. This book will encourage the exchange of information among geologists, geophysicists and signal processing researchers, and will provide them with invaluable technical know-how.

Download or read book Boundary Integral Equations written by George C. Hsiao and published by Springer Nature. This book was released on 2021-03-26 with total page 783 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second edition of the book which has two additional new chapters on Maxwell’s equations as well as a section on properties of solution spaces of Maxwell’s equations and their trace spaces. These two new chapters, which summarize the most up-to-date results in the literature for the Maxwell’s equations, are sufficient enough to serve as a self-contained introductory book on the modern mathematical theory of boundary integral equations in electromagnetics. The book now contains 12 chapters and is divided into two parts. The first six chapters present modern mathematical theory of boundary integral equations that arise in fundamental problems in continuum mechanics and electromagnetics based on the approach of variational formulations of the equations. The second six chapters present an introduction to basic classical theory of the pseudo-differential operators. The aforementioned corresponding boundary integral operators can now be recast as pseudo-differential operators. These serve as concrete examples that illustrate the basic ideas of how one may apply the theory of pseudo-differential operators and their calculus to obtain additional properties for the corresponding boundary integral operators. These two different approaches are complementary to each other. Both serve as the mathematical foundation of the boundary element methods, which have become extremely popular and efficient computational tools for boundary problems in applications. This book contains a wide spectrum of boundary integral equations arising in fundamental problems in continuum mechanics and electromagnetics. The book is a major scholarly contribution to the modern approaches of boundary integral equations, and should be accessible and useful to a large community of advanced graduate students and researchers in mathematics, physics, and engineering.
Download or read book History of Nonlinear Oscillations Theory in France 1880 1940 written by Jean-Marc Ginoux and published by Springer. This book was released on 2017-04-18 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reveals the French scientific contribution to the mathematical theory of nonlinear oscillations and its development. The work offers a critical examination of sources with a focus on the twentieth century, especially the period between the wars. Readers will see that, contrary to what is often written, France's role has been significant. Important contributions were made through both the work of French scholars from within diverse disciplines (mathematicians, physicists, engineers), and through the geographical crossroads that France provided to scientific communication at the time. This study includes an examination of the period before the First World War which is vital to understanding the work of the later period. By examining literature sources such as periodicals on the topic of electricity from that era, the author has unearthed a very important text by Henri Poincaré, dating from 1908. In this work Poincaré applied the concept of limit cycle (which he had introduced in 1882 through his own works) to study the stability of the oscillations of a device for radio engineering. The “discovery” of this text means that the classical perspective of the historiography of this mathematical theory must be modified. Credit was hitherto attributed to the Russian mathematician Andronov, from correspondence dating to 1929. In the newly discovered Poincaré text there appears to be a strong interaction between science and technology or, more precisely, between mathematical analysis and radio engineering. This feature is one of the main components of the process of developing the theory of nonlinear oscillations. Indeed it is a feature of many of the texts referred to in these chapters, as they trace the significant developments to which France contributed. Scholars in the fields of the history of mathematics and the history of science, and anyone with an interest in the philosophical underpinnings of science will find this a particularly engaging account of scientific discovery and scholarly communication from an era full of exciting developments.
