Book Synopsis The General Theory of Homogenization by : Luc Tartar
Download or read book The General Theory of Homogenization written by Luc Tartar and published by Springer Science & Business Media. This book was released on 2009-12-03 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Electric and Magnetic Fields by : R. Belmans
Download or read book Electric and Magnetic Fields written by R. Belmans and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the edited versions of the papers presented at the Second International Workshop on Electric and Magnetic Fields held at the Katholieke Universiteit van Leuven (Belgium) in May 1994. This Workshop deals with numerical solutions of electromagnetic problems in real life applications. The topics include coupled problems (thermal, mechanical, electric circuits), CAD & CAM applications, 3D eddy current and high frequency problems, optimisation and application oriented numerical problems. This workshop was organised jointly by the AIM (Association of Engineers graduated from de Montefiore Electrical Institute) together with the Departments of Electrical Engineering of the Katholieke Universiteit van Leuven (Prof. R. Belmans), the University of Gent (Prof. J. Melkebbek) and the University of Liege (Prof. W. Legros). These laboratories are working together in the framework of the Pole d'Attraction Interuniversitaire - Inter-University Attractie-Pole 51 - on electromagnetic systems led by the University of Liege and the research work they perform covers most of the topics of the Workshop. One of the principal aims of this Workshop was to provide a bridge between the electromagnetic device designers, mainly industrialists, and the electromagnetic field computation developers. Therefore, this book contains a continuous spectrum of papers from application of electromagnetic models in industrial design to presentation of new theoretical developments.

Book Synopsis History of Nonlinear Oscillations Theory in France (1880-1940) by : Jean-Marc Ginoux
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.

Book Synopsis Magnetostriction Theory and Applications of Magnetoelasticity by : Etienne Du Trémolet de Lacheisserie
Download or read book Magnetostriction Theory and Applications of Magnetoelasticity written by Etienne Du Trémolet de Lacheisserie and published by CRC Press. This book was released on 1993-06-09 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: This outstanding reference provides a comprehensive discussion of magnetoelasticity based on three accepted descriptions of magnetostriction: elastomagnetic matrices, a group symmetrical description, and a tensor formalism. It explores recent advances that rely mainly on Callen's work and emphasizes the influence of temperature, stress, and composition on the Joule magnetostriction of soft ferromagnets. The author offers a comprehensive examination of magnetoelastic effects useful for a variety of significant applications, including the Villari-, direct and inverse Wiedemann-, Matteuci-, ?E-, and invar-effects. This vital work also addresses fundamental topics, including pressure dependence of the Curie temperature, form effect, and magnetostriction in paramagnets, diamagnets, superconductors, and antiferromagnets. The last chapter is devoted to technical aspects such as experimental methods, technically useful materials (e.g., Terfenol-D and 2605SC Metglas), and various illustrative applications. Magnetostriction is one reference no physicist, materials scientist, or geophysicist should be without.

Book excerpt: NEW YORK TIMES BESTSELLER • “A fascinating look at how consumers perceive logos, ads, commercials, brands, and products.”—Time How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? In Buyology, Martin Lindstrom presents the astonishing findings from his groundbreaking three-year, seven-million-dollar neuromarketing study—a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what captures our interest—and drives us to buy. Among the questions he explores: • Does sex actually sell? • Does subliminal advertising still surround us? • Can “cool” brands trigger our mating instincts? • Can our other senses—smell, touch, and sound—be aroused when we see a product? Buyology is a fascinating and shocking journey into the mind of today's consumer that will captivate anyone who's been seduced—or turned off—by marketers' relentless attempts to win our loyalty, our money, and our minds.

Book Synopsis Machines électriques by : Jean Chatelain
Download or read book Machines électriques written by Jean Chatelain and published by EPFL Press. This book was released on 1989-01-01 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce volume consacré aux machines électriques englobe également l'étude du trans- formateur. Si la construction et le dimensionnement des machines électriques restent l'apanage d'un nombre restreint de spécialistes, leur emploi dans de multiples domaines et dans une gamme de puissances étalée de quelques mW à plusieurs centaines de MW touche un large public d'ingénieurs et de techniciens de diverses disciplines. Pour cette raison le Département d'Electricité de l'Ecole polytechnique fédérale de Lausanne conti- nue d'attribuer une large place à l'enseignement de cette matière. Le présent volume, tout en constituant un ouvrage de référence pour l'homme du métier, se veut à vocation essentiellement didactique à l'usage des candidats- ingénieurs en électrotechnique. Si certains développements peuvent apparaître exagérément détaillés, compte tenu de la littérature scientifique existante, leur inclu- sion dans l'ouvrage résulte de l'expérience acquise par l'auteur, confronté pendant 25 ans d'enseignement à des difficultés d'assimilation de la part des étudiants relati- ves à certains phénomènes de base (champ tournant, origine du couple électromagné- tique) ou certaines méthodes de calcul (matrices de transformation, théorie à deux axes, etc.). Le but assigné étant la présentation de la théorie de fonctionnement des machines électriques en régime transitoire ou permanent, les indications sur les maté- riaux et la morphologie ont été réduites au minimum nécessaire à la compréhension de la constitution spécifique de chaque type. De même, les essais n'ont fait l'objet que d'une description succincte. Afin de conserver à l'ouvrage une taille raisonnable, on a renoncé à un traite- ment complet des phénomènes transitoires par la transformation de Laplace ou les méthodes de calcul numérique et retenu seulement, à titre d'application des relations de base, le calcul détaillé des valeurs initiales de courants et de couples de court-circuit. La méthode consistant à négliger, dans un premier temps, l'amortissement est intéres- sante au plan pédagogique par l'entraînement qu'elle procure au bon choix d'hypothèses simplificatrices. La solution exacte tenant compte des amortissements a été fournie sans démonstration, afin de pouvoir définir les différentes constantes de temps (cf. chap. 6,7 et 8). La matière du volume X s'appuie sur les notions générales de l'électrotechnique (vol. I) et de l'électromécanique (vol. IX), sur certaines propriétés des matériaux (vol. II) et sur l'électromagnétisme en régime quasi-statique (vol. III). Elle fait appel égale- ment à des notions développées en électronique de puissance et de réglage (vol. XV et XVI) et en haute tension (vol. XXII).
Book Synopsis Étude des déformations magneto-élastiques dans les matériaux ferromagnétiques doux by : Laurent Hirsinger
Download or read book Étude des déformations magneto-élastiques dans les matériaux ferromagnétiques doux written by Laurent Hirsinger and published by . This book was released on 1994 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les déformations induites par les champs magnétiques dans des matériaux ferromagnétiques constituent l'une des sources du bruit émis par les machines électriques. L'identification quantitative de ces déformations représente un problème inverse délicat: elles correspondent a deux mécanismes différents viz., des déformations dues a des efforts d'origine electromagnetique et des déformations dites de magnétostriction. Une première analyse bibliographique de plusieurs formulations des efforts d'origine electromagnetique tente de justifier le choix de celle d'eringen & maugin. La deuxième partie de ce travail est consacrée a l'étude magneto-elastique expérimentale et analytique ou numérique de deux structures de géométries différentes (tore sous champ magnétique circonférentiel et plaque sous champ quasi uniaxial) mais constituées du même matériau (fer pur armco). Cette analyse constitue une tentative de validation expérimentale, d'une part de la formulation des efforts d'origine electromagnetique choisie, et d'autre part, de l'hypothèse de partition faite dans cette étude entre déformations induites par ces efforts et déformations de magnétostriction pure. Dans un troisième temps, le formalisme thermodynamique, une formulation variationnelle et les analogies entre les problèmes magnétique et thermique stationnaires sont utilises pour faire une classification des couplages entre phénomènes mécaniques, thermiques et electromagnetiques, et pour développer dans le programme de calcul industriel par éléments finis castem 2000 un outil d'analyse magneto-mecanique couplee de structures planes ou axisymétriques en matériaux aux comportements mécanique élastique linéaire et magnétique réversible non linéaire. L'application a une structure de moteur électrique a courant continu a aimants est menée et les résultats sont compares a des mesures faites sur une maquette instrumentée
