Book Description
La machine à réluctance variable à double saillance (MRV-DS) a largement été utilisée dans le domaine du positionnement incrémental. Avec les derniers progrès en électronique de puissance et de commande, le domaine d'utilisation de la MRV-DS tend à se diversifier avec des applications en fonctionnement synchrone à très grande vitesses. Quel que soit le fonctionnement envisagé, pas-à-pas ou synchrone, il est nécessaire d'élaborer un modèle de la machine pour pouvoir prédéterminer ses performances. Le mémoire de thèse est consacré à la modélisation et à l' étude de la MRV-DS dans son environnement de commande. Un modèle analytique classique est d'abord utilisé pour étudier le fonctionnement du moteur et dégager les aspects essentiels de son fonctionnement électromécanique. Il est également utilisé pour étudier le système commandé.

Book Description
This popular reference describes the integration of wind-generated power into electrical power systems and, with the use of advanced control systems, illustrates how wind farms can be made to operate like conventional power plants. Fully revised, the third edition provides up-to-date coverage on new generator developments for wind turbines, recent technical developments in electrical power conversion systems, control design and essential operating conditions. With expanded coverage of offshore technologies, this edition looks at the characteristics and static and dynamic behaviour of offshore wind farms and their connection to the mainland grid. Brand new material includes: comprehensive treatment of onshore and offshore grid integration updated legislative guidelines for the design, construction and installation of wind power plants the fundamental characteristics and theoretical tools of electrical and mechanical components and their interactions new and future types of generators, converters, power electronics and controller designs improved use of grid capacities and grid support for fixed- and variable-speed controlled wind power plants options for grid control and power reserve provision in wind power plants and wind farms This resource is an excellent guide for researchers and practitioners involved in the planning, installation and grid integration of wind turbines and power plants. It is also highly beneficial to university students studying wind power technology, renewable energy and power systems, and to practitioners in wind engineering, turbine design and manufacture and electrical power engineering.

Book Description
An exploration of the effect our celebrity-dominated culture has on our ideas of what it means to live "the good life" What would happen if an average Joe tried out for American Idol, underwent a professional makeover, endured Gwyneth Paltrow’s “Clean Cleanse,” and followed the outrageous rituals of the rich and famous? Health law policy researcher Timothy Caulfield finds out in this thoroughly unique, engaging, and provocative book about celebrity culture and its iron grip on today’s society. Over the past decade, our perceptions of beauty, health, success, and happiness have become increasingly framed by a popular culture steeped in celebrity influence and ever more disconnected from reality. Research tells us that our health decisions and goals are influenced by celebrity culture and endorsements, our children's ambitions are now overwhelmingly governed by the fantasy of fame, and the ideals of beauty and success are mediated through a celebrity-dominated worldview. But while much has been written about the cause of our obsession with the rich and famous, Caulfield argues that not enough has been done to debunk celebrity messages and promises about health, diet, beauty, or happiness. From super-thin models to Gwyneth Paltrow’s endorsement of a gluten free-diet for almost anyone, celebrity opinions have the power to dominate our conversations and outlooks. In this book, Caulfield provides an entertaining look into the celebrity world, including vivid accounts of his own experiences trying out for American Idol, having his skin resurfaced, and doing the cleanse; interviews with actual celebrities; thought-provoking facts, and a practical and evidence-based reality check on our own celebrity ambitions.
