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.

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.
Download or read book Ondes Martenot with Tubes written by Thierry Courrier and published by John Wiley & Sons. This book was released on 2023-07-12 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ondes Martenot is one of the precursors of electronic musical instruments, and is today considered, with the desire for a return to analogue, as a cult instrument. This book, which is the result of several years of research, sheds light on the intrinsic functioning of the Ondes Martenot. Based on the study of numerous prototypes, the authors trace the historical evolution of the different techniques used: additive, multiplicative and relaxation syntheses. Often, the analysis of the functioning of these instruments demonstrates atypical technological choices, underpinned by a logic that places artistic creation at the forefront. Several models and simulations are built, so as to understand the functioning of each of the different sub-assemblies (keyboard, ribbon, intensity key, timbre filter...). At the end of the book, the complete construction of an Onde (copy of model no. 208) is described in detail. This practical realization of a facsimile is an opportunity to explore the knowhow of the electronic luthier Maurice Martenot.

Download or read book Dictionary of Electronics written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: The special interest in electronics all over the world is due to its decisive role in the scien tific and technical progress now taking place in all fields of modern technology. Electronics also plays a decisive role in the development of science, providing as it does the technical basis for various scientific experiments. The role of electronics in the development of the world's culture also deserves a special mention. That is why it is hoped that the English-German French-Dutch-Russian Dictionary of Electronics, which contains some 9.000 entries and is jointly published by Kluwer Technische Boeken, B.V. (Deventer, Holland) and Ruski Yazyk Publishers (Moscow, USSR) will be favourably received. In accordance with existing international tradition, the term «electronics» covers several fields known in Soviet classification as elec tronics proper, radio engineering, and wire communication. The entries included in this dictionary have been selected in accordance with the international understanding of the term «electronics». One of the main difficulties encountered by the compilers was that although according to some calculations the number of terms used in special literature on electronics exceeds 50.000, the vocabulary of the dictionary had to be restricted to only 9.000 entries. Therefore this dictionary cannot claim to be comprehensive. Its purpose is to enable a wide range of specialists in various countries to find the English, German, French, Dutch, or Russian equivalents of the principal and most up-to-date terms in the field of electronics. Most attention has been paid to quantum electronics, fibre optics, optoelectronics, integrated circuit technology, radiolocation and radionavigation, pulse technique, holography, etc.

Download or read book Non Destructive Testing written by J. M. Farley and published by Elsevier. This book was released on 2017-05-17 with total page 935 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-Destructive Testing, Volume 4 contains the proceedings of the Fourth European Conference held in London on September 13-17, 1987. Contributors explore a variety of topics related to non-destructive testing (NDT), including ultrasonic techniques, ultrasonic systems, electromagnetic techniques, condition monitoring of plant and structures, and magnetic particle and penetrant techniques. This text is comprised of 98 chapters; the first of which describes an ultrasonic technique for the assessment of the fat content of live beef animals for breeding purposes. Attention then turns to measurements of the longitudinal ultrasonic wave attenuation in spheroidal graphite iron test pieces subjected to fatigue loads. The chapters that follow focus on ultrasonic imaging; dry coupling probes; an expert system for ultrasonic examination of fuel rods; engineering and medical applications of diagnostic ultrasound; and signal processing of 3D maps of eddy currents. The reader is also methodically introduced to automation of eddy current testing; the use of artificial intelligence in vibration-based health monitoring; automated inspection of magnetic particles; and the theory and practice of acoustic emission. This text concludes with a chapter that reviews the NDT research program of the National NDT Center of Harwell Laboratory in the UK. This book will be of interest to materials scientists, materials engineers, and metallurgists.
