Download or read book Ultra Wide Band Antennas written by Xavier Begaud and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra Wide Band Technology (UWB) has reached a level of maturity that allows us to offer wireless links with either high or low data rates. These wireless links are frequently associated with a location capability for which ultimate accuracy varies with the inverse of the frequency bandwidth. Using time or frequency domain waveforms, they are currently the subject of international standards facilitating their commercial implementation. Drawing up a complete state of the art, Ultra Wide Band Antennas is aimed at students, engineers and researchers and presents a summary of internationally recognized studies.

Download or read book Engineering Acoustics written by Michael Möser and published by Springer Science & Business Media. This book was released on 2009-09-01 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Suitable for both individual and group learning, Engineering Acoustics focuses on basic concepts and methods to make our environments quieter, both in buildings and in the open air. The author’s tutorial style derives from the conviction that understanding is enhanced when the necessity behind the particular teaching approach is made clear. He also combines mathematical derivations and formulas with extensive explanations and examples to deepen comprehension. Fundamental chapters on the physics and perception of sound precede those on noise reduction (elastic isolation) methods. The last chapter deals with microphones and loudspeakers. Moeser includes major discoveries by Lothar Cremer, including the optimum impedance for mufflers and the coincidence effect behind structural acoustic transmission. The appendix gives a short introduction on the use of complex amplitudes in acoustics.

Download or read book La machine asynchrone vitesse variable written by Hubert Razik and published by . This book was released on 2006 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: La machine asynchrone à vitesse variable, ouvrage en deux volumes, présente le moteur asynchrone, son modèle et son comportement en régime statique ou dynamique, dans son contexte environnemental. Il rassemble la modélisation et l'étude des différentes composantes d'un actionneur électrique : asservissements, organes de mesure, commande numérique et chaînes de puissance [...] Ce deuxième volume étudie l'aspect variation de vitesse du moteur, les notions de la logique floue puis la mesure des signaux et leurs traitements. La commande vectorielle ainsi que diverses stratégies (telles que DTC, FOC, SVM, etc.) sont également présentées. Enfin, l'ouvrage explique les éléments relatifs à la détection d'un défaut d'ordre électrique ou mécanique [source : 4ème de couverture]

Download or read book La commande lectronique des machines written by Michel Pinard and published by Dunod. This book was released on 2013-08-28 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage permet de maîtriser les bases du contrôle et de la commande des machines électriques. Il est constitué d'une soixantaine de fiches pratiques rassemblées dans huit dossiers thématiques. Ces dossiers abordent successivement les questions des alimentations électriques, des convertisseurs de puissance, des différents types de machines (synchrones ou asynchrones), et des différents modes de commande et d'asservissement. Chaque fiche pose un problème précis et ponctuel et en explique la solution. Dans de nombreux cas, des simulations sur les logiciels tels que PSIM, VisSIM et LabVIEW permettent une approche concrète et opérationnelle des difficultés rencontrées dans la mise au point d'un système de commande.
