Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL S'INSCRIT DANS LE CADRE DES RECHERCHES EFFECTUEES A L'INRIA POUR L'AMELIORATION DE LA COMMANDE DES MANIPULATEURS RIGIDES. L'OBJECTIF DE CETTE ETUDE EST DE METTRE AU POINT UNE COMMANDE ROBUSTE ET PERFORMANTE POUR DES MODULES DE TRANSLATION ET DE ROTATION, CONSTITUES DE COMPOSANTS HYDRAULIQUES. CES MODULES DE MOTRICITE SONT CONCUS POUR CONSTRUIRE UN MANIPULATEUR D'ASSEMBLAGE EN MICRO-MECANIQUE DONT UN PROTOTYPE EST EN COURS DE REALISATION. LES CONTRAINTES ESSENTIELLES QUE DOIT RESPECTER UN ROBOT UTILISABLE DANS UN ATELIER FLEXIBLE D'ASSEMBLAGE AUTOMATIQUE, SONT LA RAPIDITE, LA PRECISION, LA ROBUSTESSE ET LA MODULARITE. CES DIFFERENTS ASPECTS SONT PRIS EN COMPTE POUR LE CHOIX DE LA STRUCTURE GEOMETRIQUE, DES ACTIONNEURS DU MANIPULATEUR ET AUSSI DANS LA REALISATION DE LA COMMANDE. AINSI, A PARTIR D'UN MODELE DE CONNAISSANCE ETABLIT GRACE A UNE MODELISATION PRECISE DES MODULES DE MOTRICITE, UN REGULATEUR ISSU DES TECHNIQUES DE COMMANDE LINEAIRE ET DE COMMANDE OPTIMALE EST DEVELOPPE. LA VALIDATION DE L'ALGORITHME DE CONTROLE EST FAITE PAR SIMULATION EN TENANT COMPTE DES CARACTERISTIQUES DES ACTIONNEURS HYDRAULIQUES, MAIS AUSSI DES COUPLAGES ET DES VARIATIONS D'INERTIE DANS LE CAS OU LES MODULES DE MOTRICITE SONT ASSOCIES EN UNE CONFIGURATION RPP. L'ETUDE COMPREND L'IMPLANTATION DES ALGORITHMES DE CONTROLE DANS UN ENSEMBLE MULTIPROCESSEURS

Download or read book Cambridge Handbook of Engineering Education Research written by Aditya Johri and published by Cambridge University Press. This book was released on 2014-02-10 with total page 1124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.
Download or read book Engineering written by Unesco and published by UNESCO. This book was released on 2010-01-01 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report reviews engineering's importance to human, economic, social and cultural development and in addressing the UN Millennium Development Goals. Engineering tends to be viewed as a national issue, but engineering knowledge, companies, conferences and journals, all demonstrate that it is as international as science. The report reviews the role of engineering in development, and covers issues including poverty reduction, sustainable development, climate change mitigation and adaptation. It presents the various fields of engineering around the world and is intended to identify issues and challenges facing engineering, promote better understanding of engineering and its role, and highlight ways of making engineering more attractive to young people, especially women.--Publisher's description.

Download or read book Prophets of the Posthuman written by Christina Bieber Lake and published by University of Notre Dame Pess. This book was released on 2013-09-30 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prophets of the Posthuman provides a fresh and original reading of fictional narratives that raise the question of what it means to be human in the face of rapidly developing bioenhancement technologies. Christina Bieber Lake argues that works by Nathaniel Hawthorne, Walker Percy, Flannery O'Connor, Toni Morrison, George Saunders, Marilynne Robinson, Raymond Carver, James Tiptree, Jr., and Margaret Atwood must be reevaluated in light of their contributions to larger ethical questions. Drawing on a wide range of sources in philosophical and theological ethics, Lake claims that these writers share a commitment to maintaining a category of personhood more meaningful than that allowed by utilitarian ethics. Prophets of the Posthuman insists that because technology can never ask whether we should do something that we have the power to do, literature must step into that role. Each of the chapters of this interdisciplinary study sets up a typical ethical scenario regarding human enhancement technology and then illustrates how a work of fiction uniquely speaks to that scenario, exposing a realm of human motivations that might otherwise be overlooked or simplified. Through the vision of the writers she discusses, Lake uncovers a deep critique of the ascendancy of personal autonomy as America’s most cherished value. This ascendancy, coupled with technology’s glamorous promises of happiness, helps to shape a utilitarian view of persons that makes responsible ethical behavior toward one another almost impossible. Prophets of the Posthuman charts the essential role that literature must play in the continuing conversation of what it means to be human in a posthuman world.
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1976 with total page 320 pages. 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.
