Available in PDF, EPUB and Kindle. Book excerpt: La démocratisation des nouvelles plateformes d'exécution parallèles et distribuées, notamment les grilles de calcul, a engendré l'émergence de nouvelles d'architectures constituées en grande partie par des ressources fournies par des personnes/organisations volontaires. Ces machines ne sont pas disponibles tout le temps. Elles sont sujettes à des perturbations liées aux incertitudes sur les dates de début et de fin de disponibilités. Pour générer des ordonnancements adaptés à ces plateformes, nous cherchons à optimiser, en plus des fonctions objectifs classiques, un nouveau critère qui caractérise l'aptitude de l'ordonnancement à absorber l'effet des perturbations (la stabilité). Nous nous sommes intéressés dans le cadre de ce travail au problème de l'ordonnancement avec contraintes d'indisponibilité de ressources et d'incertitudes sur les dates d'occurrence des évènements. Nous commençons par étudier le cas préliminaire de ce problème où une seule indisponibilité est possible par machine et où l'incertitude porte sur la durée de l'indisponibilité. Nous généralisons ensuite cette étude pour le cas où plusieurs indisponibilités peuvent être envisagées sur les machines et où l'incertitude porte sur les dates d'occurrences des évènements. Pour l'ensemble de ces problèmes, nous utilisons une technique de tampon pour fournir une famille d'ordonnancements qui optimisent simultanément la performance et la stabilité des ordonnancements générés. Une vaste campagne de simulation des heuristiques proposées conduit à la sélection de configurations qui aboutissent à des résultats satisfaisants en terme de compromis. Mots clés : Parallélisme, ordonnancement, incertitude, disponibilité, stabilité

Download or read book Local Applications of the Ecological Approach To Human Machine Systems written by Peter A. Hancock and published by CRC Press. This book was released on 2018-05-02 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing consensus in the human factors/ergonomics community that human factors research has had little impact on significant applied problems. Some have suggested that the problem lies in the fact that much HF/E research has been based on the wrong type of psychology, an information processing view of psychology that is reductionistic and context-free. Ecological psychology offers a viable alternative, presenting a richer view of human behavior that is holistic and contextualized. The papers presented in these two volumes show the conceptual impact that ecological psychology can have on HF/E, as well as presenting a number of specific examples illustrating the ecological approach to human-machine systems. It is the first collection of papers that explicitly draws a connection between these two fields. While work in this area is only just beginning, the evidence available suggests that taking an ecological approach to human factors/ergonomics helps bridge the existing gap between basic research and applied problems.
Download or read book Arctic Shipping written by Frédéric Lasserre and published by Routledge. This book was released on 2019-09-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.

Download or read book Max Weber and Karl Marx written by Karl Lowith and published by Routledge. This book was released on 2002-11-01 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: First Published in 2004. Lowith's study of Max Weber and Karl Marx is a key text in modem interpretations of the theme of alienation in Marxist theory and rationalisation in Weber's sociology. It remains the best short student introduction to the differences and comparisons between these essential thinkers. This new edition includes a Preface by Professor Bryan S. Turner which demonstrates the relevance of the book for contemporary sociology.
Download or read book An Introduction to Differential Manifolds written by Jacques Lafontaine and published by Springer. This book was released on 2015-07-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.

Available in PDF, EPUB and Kindle. Book excerpt: This book approaches the notion of good governance from three different angles. First it establishes whether it is a meaningful notion at all by taking a closer look at the parameters of good governance. Secondly, the authors look at the institutional translation of the criteria of good governance. In a third dimension, the concept may be analysed in relation to a number of substantive issues.
