Book excerpt: Dans ce livre, nous allons presenter en premier lieu une etude de modelisation Machine Asynchrone Double Etoile et sa d'alimentation. La commande de la MASDE alimentee par deux onduleurs a hysteresis, utilisant de regulateur PI classiques presente certains inconvenients tels que la sensibilite aux variations parametriques de la machine. Au niveau des techniques de commande, on a applique des strateges de reglage robustes a savoir: la logique floue, le mode glissant et le modele de reference MARC, ce dernier partie est une explication de reglage par chaque methode de commande precedente qui permet d'exploiter la robustesse et la rapidite durant le regime transitoire, et la flexibilite du controleur durant le regime permanent. Les resultats simulations montrent le bon controle de l'orientation de flux rotorique de la machine MASDE, ainsi que le reglage de la vitesse de rotation a travers les controleurs proposes. Generalement cet ouvrage, s'adresse principalement aux enseignants et aux etudiants, mais aussi d'un public plus large a la recherche d'informations precis

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

Book excerpt: Greenhouses are framed or inflated structures, covered with transparent or translucent material in which crops are grown. Greenhouse cultivation and other models of environment cultivation have been evolved to create favourable micro-climates under which crop production is made possible. Greenhouse food production provides forward movement with a greater degree of environment control. It presents the ultimate in intensive agriculture considering three major factors: land; labour; and capital.
