This book was released on 2014-03-13 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'energie electrique est devenue au fil des annees un element vital, c'est ainsi que les pays veillant au bien etre de leurs citoyens mettent en uvre tous les moyens necessaires pour fournir une electricite fiable, durable et au moindre cout. Les pays africains y compris le Maroc s'est lance recemment dans des projets de production d'energie electrique, a savoir l'energie solaire et eolienne, d'ou la necessite des reseaux de transport de cette energie. Le present projet vise la conception d'une nouvelle famille de pylone en structures metalliques, pour le transport d'energie electrique de la tres haute tension de 400KV.Cette conception doit repondre aux exigences des cahiers de charge ainsi qu'aux differentes conditions climatiques et geographiques du terrain. Pour ce faire; on s'est lance dans l'etude de la ligne, affin de calculer les efforts appliques au pylone, pour entamer, par la suite, le calcul geometrique definissant la silhouette de notre pylone, tout en respectant les exigences de cahier de charge.Et par la suite nous avons verifie les structures sous le logiciel PLS-TOWER pour la verification de la tenue mecanique.
Download or read book Cleaner Combustion written by Frédérique Battin-Leclerc and published by Springer Science & Business Media. This book was released on 2013-09-06 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: This overview compiles the on-going research in Europe to enlarge and deepen the understanding of the reaction mechanisms and pathways associated with the combustion of an increased range of fuels. Focus is given to the formation of a large number of hazardous minor pollutants and the inability of current combustion models to predict the formation of minor products such as alkenes, dienes, aromatics, aldehydes and soot nano-particles which have a deleterious impact on both the environment and on human health. Cleaner Combustion describes, at a fundamental level, the reactive chemistry of minor pollutants within extensively validated detailed mechanisms for traditional fuels, but also innovative surrogates, describing the complex chemistry of new environmentally important bio-fuels. Divided into five sections, a broad yet detailed coverage of related research is provided. Beginning with the development of detailed kinetic mechanisms, chapters go on to explore techniques to obtain reliable experimental data, soot and polycyclic aromatic hydrocarbons, mechanism reduction and uncertainty analysis, and elementary reactions. This comprehensive coverage of current research provides a solid foundation for researchers, managers, policy makers and industry operators working in or developing this innovative and globally relevant field.

Download or read book A Coat of Many Colors written by Gregory Freidin and published by Univ of California Press. This book was released on 2010-05-13 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Friedin writes just the kind of criticism Mandelstam wrote and which he would have loved: grounded in careful reading but never timid, quirky but never merely eccentric, the product of a mind and sensibility keenly alive to the times, both historical and critical. . . . Nothing I have read on Mandelstam has so provoked my own thinking as has Freidin's work. . . . It is stimulating in every sense of the word and will move the study of Mandelstam off the point at which it has been stuck for far too long." - John E. Malmstad, Harvard University "Combining as it does sensitive close readings of the Mandelstam texts with an uncommonly wide range of literary and sociocultural reference, A Coat of Many Colors is a welcome and significant addition to the body of scholarship bearing on one of our century's finest poets." -Victor Erlich, Yale University
Download or read book Unsteady Transonic Flow written by Mårten T. Landahl and published by Courier Dover Publications. This book was released on 2019-04-17 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic monograph on unsteady transonic flow — the flow of air encountered at speeds at or near the speed of sound — is of continuing interest to students and professionals in aerodynamics, fluid dynamics, and other areas of applied mathematics. After a brief Introduction, Swedish physicist Mårten T. Landahl presents a chapter in which the two-dimensional solution is derived, succeeded by a discussion of its relation to the subsonic and supersonic solutions. Three chapters on low aspect ratio configurations follow, covering triangular wings and similar planforms with curved leading edges, rectangular wings, and cropped delta wings, and low aspect ratio wing-body combinations. The treatment concludes with a consideration of the experimental determination of air forces on oscillating wings at transonic speeds.
