Book Description
L'électrotechnique est une discipline où la recherche nous apporte périodiquement de nouvelles applications, tandis que de nouveaux besoins ne cessent de se faire jour. L'intérêt que suscite cette discipline déjà classique s'en trouve donc constamment stimulé, invitant tous ceux qui souhaitent suivre cette évolution à découvrir ou à redécouvrir ce domaine porteur d'emplois et ouvrant aux nombreuses carrières de techniciens, d'ingénieurs et de chercheurs. Par sa polyvalence et sa souplesse, l'énergie électrique est au coeur des échanges d'énergie. Ce manuel permettra aux étudiants inscrits dans les différents premiers cycles de l'enseignement supérieur et aux professionnels en formation continue d'étudier - avec des méthodes actuelles - l'électrotechnique telle qu'on la pratique aujourd'hui; les problèmes reposent donc sur des données industrielles et techniques. La part faite aux études de cas et aux exercices corrigés constitue un des meilleurs atouts de cet ouvrage où l'on verra que, chaque fois que cela est possible, le problème précède le cours. Toutefois, pour que l'on soit encouragé à le résoudre, la solution est le plus souvent déjà dans l'énoncé. Enfin, pour résoudre les problèmes à la calculatrice ou à l'ordinateur, la simulation informatique et les méthodes de calcul informatisées sont ici très largement utilisées.

Book Description
The Violence of Modernity turns to Charles Baudelaire, one of the most canonical figures of literary modernism, in order to reclaim an aesthetic legacy for ethical inquiry and historical critique. Works of modern literature are commonly theorized as symptomatic responses to the trauma of history. In a climate that tends to privilege crisis over critique, Debarati Sanyal argues that it is urgent to rethink literary experience in terms that recall its contestatory potential. Examining Baudelaire's poems afresh, she shifts the focus of critical attention toward an account of modernism as an active engagement with violence, specifically the violence of history in nineteenth-century France. Sanyal analyzes a literary current that uses the traditional hallmarks of modernism—irony, intertextuality, self-reflexivity, and formalism—to challenge the historical violence of modernity. Baudelaire and the committed ironists writing in his wake teach us how to read and resist the violence of history, and thereby to challenge the melancholy tenor of our contemporary "wound culture." In a series of provocative readings, Sanyal presents Baudelaire's poetry as an aesthetic form that contests historical violence through rhetorical strategies of complicity, counterviolence, and critique. The book develops a new account of Baudelaire's significance as a modernist by dislodging him both from his traditional status as a practitioner of "art for art's sake" and from his more recent incarnation as the poet of trauma. Following her extended analysis of Baudelaire's poetry, Sanyal in later chapters considers a number of authors influenced by his strategies—including Rachilde, Virginie Despentes, Albert Camus, and Jean-Paul Sartre—to examine the relevance of their interventions for our current climate of trauma and terror. The result is a study that underscores how Baudelaire's legacy continues to energize literary engagements with the violence of modernity.

Book Description
SCIENCE AND EMPIRES: FROM THE INTERNATIONAL COLLOQUIUM TO THE BOOK Patrick PETITJEAN, Catherine JAMI and Anne Marie MOULIN The International Colloquium "Science and Empires - Historical Studies about Scientific De velopment and European Expansion" is the product of an International Colloquium, "Sciences and Empires - A Comparative History of Scien tific Exchanges: European Expansion and Scientific Development in Asian, African, American and Oceanian Countries". Organized by the REHSEIS group (Research on Epistemology and History of Exact Sciences and Scientific Institutions) of CNRS (National Center for Scientific Research), the colloquium was held from 3 to 6 April 1990 in the UNESCO building in Paris. This colloquium was an idea of Professor Roshdi Rashed who initiated this field of studies in France some years ago, and proposed "Sciences and Empires" as one of the main research programmes for the The project to organize such a colloquium was a bit REHSEIS group. of a gamble. Its subject, reflected in the title "Sciences and Empires", is not a currently-accepted sub-discipline of the history of science; rather, it refers to a set of questions which found autonomy only recently. The terminology was strongly debated by the participants and, as is frequently suggested in this book, awaits fuller clarification.

Book Description
Play is one of humanity's straightforward yet deceitful ideas: though the notion is unanimously agreed upon to be universal, used for man and animal alike, nothing defines what all its manifestations share, from childish playtime to on stage drama, from sporting events to market speculation. Within the author's anthropological field of work (Mongolia and Siberia), playing holds a core position: national holidays are called "Games," echoing in that way the circus games in Ancient Rome and today's Olympics. These games convey ethical values and local identity. Roberte Hamayon bases her analysis of the playing spectrum on their scrutiny. Starting from fighting and dancing, encompassing learning, interaction, emotion and strategy, this study heads towards luck and belief as well as the ambiguity of the relation to fiction and reality. It closes by indicating two features of play: its margin and its metaphorical structure. Ultimately revealing its consistency and coherence, the author displays play as a modality of action of its own. "Playing is no 'doing' in the ordinary sense" once wrote Johan Huizinga. Isn't playing doing something else, elswhere and otherwise ?

Book Description
This book is about electric energy: its generation, its transmission from the point of generation to where it is required, and its transformation into required forms. To achieve this end, a number of devices are essential-such as generators, trans mission lines, transformers, and electric motors. We discuss the design, construc tion, and operating characteristics of the electric devices used in the transformation to and from electric energy. This text is designed to be used in a one-semester course in electric energy con version at the second-year level of the Bachelor of Engineering course. It is assumed that the student is familiar with the laws of thermodynamics and has taken a course in basic circuit analysis, including the application of phasors. We begin with a discussion of how humankind has successfully harnessed the energy of wind, water, the sun, biomass, animals, geothermal sources, fossils, and nuclear fission to make its life comfortable. Some of the consequences of this activity on the environment are examined. In Chapter 2, we review the basic physics of energy and its conversion. This may be, to some extent, a repetition of knowledge gained in high-school and first year university courses. However, we believe that such review is necessary to establish a suitable base from which to launch the subject of electric energy con version.

Book Description
Bourdieu and Literature is a wide-ranging, rigorous and accessible introduction to the relationship between Pierre Bourdieu's work and literary studies. It provides a comprehensive overview and critical assessment of his contributions to literary theory and his thinking about authors and literary works. One of the foremost French intellectuals of the post-war era, Bourdieu has become a standard point of reference in the fields of anthropology, linguistics, art history, cultural studies, politics, and sociology, but his longstanding interest in literature has often been overlooked. This study explores the impact of literature on Bourdieu's intellectual itinerary, and how his literary understanding intersected with his sociological theory and thinking about cultural policy. This is the first full-length study of Bourdieu's work on literature in English, and it provides an invaluable resource for students and scholars of literary studies, cultural theory and sociology.
