Download or read book La machine asynchrone à 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]

Book Synopsis Détermination indirecte du glissement du moteur asynchrone alimenté à tension et à fréquence variables by : Michèle Rombaut
Download or read book Détermination indirecte du glissement du moteur asynchrone alimenté à tension et à fréquence variables written by Michèle Rombaut and published by . This book was released on 1984 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surtout dans les équipements à vitesse variable, la commande et la protection du moteur asynchrone triphasé demandent la connaissance de la grandeur caractérisant le mieux le fonctionnement de la machine, son glissement ou, ce qui revient au même, sa fréquence rotorique. Pour les moteurs à cage, la mesure du glissement nécessitait un capteur tachymétrique dont le cout et les inconvénients s'opposaient à l'automatisation de nombreux équipements. L'objets de cette thèse est de montrer comment on peut déterminer indirectement le glissement à partir des seules grandeurs statoriques : fréquence, tension, courant et déphasage. L'auteur rappelle d'abord les procédés de variation de vitesse du moteur asynchrone, les avantages de la commande à flux constant, et montre l'intérêt pour celle-ci de la connaissance de la fréquence rotorique. Un algorithme simple permet la détermination de cette fréquence à partir des grandeurs statoriques à condition d'avoir, dans une phase de reconnaissance préalable, relevé les paramètres caractéristiques de la machine. Mais ces paramètres varient : il est possible de prendre en compte ces variations par une utilisation judicieuse de l'algorithme. L'auteur présente ensuite l'équipement prototype réalisé qui nécessite l'emploi d'un microprocesseur : convertisseur, électronique de commande, régulation, interfacage avec le microprocesseur. Celui-ci guide l'utilisateur pendant la phase de reconnaissance, mémorise les informations recueillies. Ensuite, en fonctionnement normal, à partir de ces informations et des grandeurs mesurées, il calcule et affiche le glissement

Book Synopsis Adaptive Stream Mining by : Albert Bifet
Download or read book Adaptive Stream Mining written by Albert Bifet and published by IOS Press. This book was released on 2010 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a significant contribution to the subject of mining time-changing data streams and addresses the design of learning algorithms for this purpose. It introduces new contributions on several different aspects of the problem, identifying research opportunities and increasing the scope for applications. It also includes an in-depth study of stream mining and a theoretical analysis of proposed methods and algorithms. The first section is concerned with the use of an adaptive sliding window algorithm (ADWIN). Since this has rigorous performance guarantees, using it in place of counters or accumulators, it offers the possibility of extending such guarantees to learning and mining algorithms not initially designed for drifting data. Testing with several methods, including Naïve Bayes, clustering, decision trees and ensemble methods, is discussed as well. The second part of the book describes a formal study of connected acyclic graphs, or 'trees', from the point of view of closure-based mining, presenting efficient algorithms for subtree testing and for mining ordered and unordered frequent closed trees. Lastly, a general methodology to identify closed patterns in a data stream is outlined. This is applied to develop an incremental method, a sliding-window based method, and a method that mines closed trees adaptively from data streams. These are used to introduce classification methods for tree data streams.

Book Synopsis Neuroscientific Foundations of Anesthesiology by : George A. Mashour
Download or read book Neuroscientific Foundations of Anesthesiology written by George A. Mashour and published by Oxford University Press. This book was released on 2011-10-05 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the perioperative care of patients by anesthesiologists draws on diverse clinical skills, the principles of anesthesiology and pain management are rooted in the neurosciences. The Neuroscientific Foundations of Anesthesiology thoroughly examines the anesthetic modulation of the central, peripheral, and autonomic nervous systems and will help redefine anesthesiology as a fundamentally neuroscientific field. The book is organized by sections, with each focusing on a different part of the nervous system. State-of-the-art chapters written by thought-leaders in anesthesiology and neuroscience provide a novel and invaluable resource.
