Download or read book Propagation d'ondes accoustiques et élastiques written by BRAC Jean and published by Lavoisier. This book was released on 2003-01-01 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage propose une méthode de construction de schémas numériques de grande précision sur la base d'une analyse spectrale de l'erreur. Ces schémas sont appliqués à la propagation des ondes mais ils peuvent l'être à la résolution par différences finies de tout autre système d'équations aux dérivées partielles. Plusieurs formulations du problème continu sont exposées mais on retient la formulation en vitesses de déplacement et en contraintes. D'autre part, une analyse des caractéristiques des équations de la propagation conduit à faire une comparaison avec les caractéristiques des équations de la mécanique des fluides et d'indiquer les conditions de la filiation. La discrétisation des équations est basée sur les schémas en grilles décalées. On effectue des développements de Taylor à des ordres élevés et une analyse de l'erreur de discrétisation par transformée de Fourier. Puis, on introduit la notion d'approximation optimale en contraste avec les approximations basées sur l'erreur de troncature. Les schémas construits restent de type convolutif. Le calcul s'avère très efficace sur la base de l'erreur relative de discrétisation. L'algorithme de calcul des coefficients d'approximation optimale est fourni en Fortran dans une annexe. L'élévation de l'ordre en temps consiste à reporter le calcul des dérivées d'ordre élevé en temps sur des dérivées d'ordre élevé en espace. Enfin, l'analyse des conditions de stabilité et de dispersion est réalisée pour prendre en compte l'approximation optimale des dérivées pour des ordres élevés en espace et en temps.

Available in PDF, EPUB and Kindle. Book excerpt: A new generation of observatories, now being completed worldwide, will give astronomers not just a new window on the cosmos but a whole new sense with which to explore and experience the heavens above us. Instead of collecting light waves or radio waves, these novel instruments will allow astronomers to at last place their hands upon the fabric of space-time and feel the very rhythms of the universe. These vibrations in space-time-or gravity waves-are the last prediction of Einstein's general theory of relativity yet to be observed directly. They are his unfinished symphony, waiting nearly a century to be heard. When they finally reveal themselves to astronomers, we will for the first time be able to hear the cymbal crashes from exploding stars, tune in to the periodic drumbeats from swiftly rotating pulsars, listen to the extended chirps from the merger of two black holes, and eavesdrop on the remnant echoes from the mighty jolt of the Big Bang itself. When Einstein introduced general relativity in 1915, it was hailed as a momentous conceptual achievement. Einstein attained celebrity status. But, once scientists verified what they could of the theory, given the scant experiments available at the time, general relativity became "largely a theoretical curiosity," writes Marcia Bartusiak. Now, after decades of technological advancement, general relativity is being tested with unprecedented accuracy. It even affects our everyday lives. Satellites used by both travelers and soldiers to peg their positions require constant corrections of Einsteinian precision. Meanwhile, the first gravity-wave "telescopes"--Including the LIGO facility-are about to come alive.

This book was released on 2012-04-16 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce livre propose une synthèse des recherches - des concepts jusqu'aux applications - sur les matériaux artificiels, incluant les cristaux photoniques et les métamatériaux. Il expose les enjeux de performance et les défis de fabrication (jusqu'à l'échelle du nanomètre) pour l'exploitation des effets d'ultra-réfraction ou de réfraction négative induits par l'ingénierie généralisée ou localisée de la dispersion sur l'ensemble du spectre électromagnétique (des micro-ondes à l'optique en passant par le térahertz et l'infrarouge). Didactique, Matériaux artificiels analyse les possibilités de l'optique de transformation tels que les mirages optiques, les lentilles parfaites, les tapis magiques et les capes d'invisibilité. Présentés comme potentiels précurseurs de nouveaux systèmes de contrôle de la propagation des ondes et/ou d'imagerie pour les domaines des télécommunications, de la biologie ou de la médecine, ils permettent d'identifier les principaux verrous théoriques et technologiques actuels.

Book excerpt: Foreword The modern developments in mathematical biology took place roughly between 1920 and 1940, a period now referred to as the "Golden Age of Theoretical Biology". The eminent Italian mathematician Vito Volterra played a decisive and widely acknowledged role in these developments. Volterra's interest in the application of mathematics to the non physical sciences, and to biology and economics in particular, dates back to the turn of the century and was expressed in his inaugural address at the University of Rome for the academic year 1900/01 (VOLTERRA 1901). Nevertheless, it was only in the mid-twenties that Volterra entered the field in person, at the instigation of his son in law, Umberto D'Ancona, who had confronted him with the problem of competition among animal species, asking him whether a mathematical treatment was possible. From that time on, until his death in 1940, Volterra produced a huge output of publications on the subject. Volterra's specific project was to transfer the model and the concepts of classical mechanics to biology, constructing a sort of "rational mechanics" and an "analytic mechanics" of biological associations. The new subject was thus to be equipped with a solid experimental or at least empirical basis, also in this case following the tried and tested example of mathematical physics. Although very few specific features of this reductionist programme have actually survived, Volterra's contribution was decisive, as is now universally acknowledged, in en couraging fresh studies in the field of mathematical biology.

This book was released on 2013-09-11 with total page 667 pages. Available in PDF, EPUB and Kindle. Book excerpt: Un DVD inclus avec des séquences vidéos inédites pour chaque chapitre ! L’épileptologie change, et les approches syndromiques sont maintenant complétées par une approche étiologique fondée sur les progrès considérables en génétique. Une approche purement « électro-clinique » n’est plus adaptée aujourd’hui dans bien des cas. Cette 5e édition du « Guide bleu » fait le point sur les plus récents progrès. Ainsi, la structure du livre a un peu évolué, laissant plus de place aux approches : - physiologiques - épidémiologiques - génétiques - thérapeutique Néanmoins, la description des syndromes épileptiques reste au cœur de cet ouvrage. La diversité des contributeurs – coordinateurs et auteurs – confère à ce livre des qualités d’objectivité et de sérieux qui en font la réputation depuis maintenant près de 30 ans.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in Refrigeration Science and Technology, Volume I is a collection of papers from the Eleventh International Congress of Refrigeration held in Munich in August-September 1963. These papers deal with the various scientific and technical aspects, designs, and technology of refrigeration. One paper explains technological advances in the use of very low temperature fluids, namely liquid hydrogen and liquid helium as rocket fuels, as bubble chambers, in the study of mesons or hyperons, and in experiments involving the reaction of metals in a wide range of temperature. Another paper examines the requirements for improved food refrigeration and the limitations of certain methods when compared to other cold processing forms. Freeze-drying is also used in biology such as in freeze-drying of biological solutions, tissues, or living organisms. One paper explains the purification method for obtaining very pure hydrogen at high pressures to be used in comparative experiments on the thermodynamical properties of ortho- and para-hydrogen, and their mixtures. Another paper investigates the effect of heat exchange between capillary tube and suction line on the performance of small hermetic compressor systems. This collection is suitable for engineers or technologists in the area of refrigeration, as well as for scientists involved in the space industry and materials research.

Download or read book Électrographies de fond de mer – une révolution dans la prospection pétrolière ? written by SAINSON Stéphane and published by Lavoisier. This book was released on 2012-05-02 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’électrographie de fond de mer (EFM) regroupe les méthodes électromagnétiques d’exploration du sous-sol marin et plus spécifiquement celles dédiées à la prospection des hydrocarbures en mer. Apparues commercialement en 2000, ces techniques, avec plus de 500 opérations industrielles, présentent après 10 ans de succès commerciaux un taux record de découverte de près de 90 %, et semblent aujourd’hui bouleverser la donne en matière de recherche pétrolière offshore. En proposant un indice de présence d’hydrocarbures sérieux, l’EFM couplée à la sismique réflexion est probablement la première méthode fiable de détection directe des hydrocarbures. Complétant les concepts structuralistes de la prospection indirecte en vigueur depuis les années 1920, l’EFM modifie aujourd’hui radicalement l’approche et les philosophies d’exploration, en particulier celles incluant en aval les activités de forages et de diagraphies de fond de trou. S’appuyant sur les lois de l’électromagnétisme (équations de Maxwell), Électrographies de fond de mer décrit et analyse en détail les principes physiques, les méthodes, les techniques et les technologies mis en œuvre ou en voie de l’être. De plus, une note historique montrant l’évolution des idées, des concepts et des matériels depuis les années 1930, dates des premières tentatives, complète chaque chapitre. Synthèse unique, cet ouvrage abondamment illustré constitue un véritable outil de réflexion sur l’utilisation en prospection de l’énergie électromagnétique en milieu conducteur (eau de mer) fixant ainsi les limites théoriques et pratiques de ces investigations pour les développements à venir. Destiné aux géophysiciens et géologues du pétrole, il sera également utile aux physiciens du globe, aux ingénieurs réservoir, aux diagraphistes, aux log analysts, ainsi qu’à tous les étudiants en géosciences.
