Available in PDF, EPUB and Kindle. Book excerpt: Nous étudions la prévision du jour pour le lendemain de la consommation électrique agrégée à la maille des points de livraison, à partir des informations calendaires, des prévisions météorologiques et des valeurs récentes de ces séries temporelles. Ce travail s'inscrit dans un domaine de recherche plus large, qui participe à la modernisation du système électrique français. Avec la pénétration des énergies renouvelables et l'apparition de nouveaux modes de consommation, le besoin d'améliorer la qualité des prévisions au niveau local devient de plus en plus pressant. Acteur central du système électrique, le Gestionnaire du Réseau de Transport (GRT) est responsable de l'équilibre offre-demande et assure en permanence la fluidité de la circulation d'électricité sur le réseau haute tension. La prévision de la consommation est donc pour lui une problématique de recherche centrale. Le développement d'algorithmes modernes de Machine Learning, l'augmentation des capacités de calcul et la disponibilité de grandes bases de données électriques et météorologiques laissent entrevoir de nouvelles opportunités.Après une analyse exploratoire de la base de données et une étude de la littérature portant sur la prévision de la consommation électrique, nous considérons la possibilité d'étendre et d'adapter les modèles utilisés pour la prévision à des mailles plus larges comme les régions ou le pays. Cela nous permet de souligner les comportements plus hétérogènes au niveau des points de livraison de ces séries temporelles. L'ensemble des expériences est organisé autour d'une dichotomie entre des modèles à différents noeuds du réseau appris de façon indépendante ou bien couplée. Plus précisément, nous justifions une approche multi-tâches de ces prévisions avec les similarités entre les courbes aux différents noeuds du réseau, qui vise à améliorer la vitesse d'apprentissage de ces modèles ainsi que leur capacité à généraliser.Nous séparons l'approche multi-tâches en trois questions. Quelles composantes des modèles est-il pertinent de coupler ? Quelles améliorations ce couplage peut-il apporter ? Comment évaluer la pertinence de l'approche multi-tâches dans le cadre de la prévision de la consommation électrique ?Nous envisageons trois couplages possibles des modèles de prévision, fondés respectivement sur un clustering des coefficients des modèles, une hypothèse de rang faible sur la matrice de coefficients, et une mesure de la cohérence des prévisions à différents niveaux d'agrégation. Empiriquement, nous montrons le caractère contingent du grand nombre de coefficients des modèles appris indépendamment et confirmons l'intérêt de coupler les fonctions objectifs à minimiser ainsi que les paramètres des modèles au cours de leur apprentissage.

Download or read book Dam break Problems Solutions and Case Studies written by D. De Wrachien and published by WIT Press. This book was released on 2009 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the book is to give an up-to-date review on dam-break problems, along with the main theoretical background and the practical aspects involved in dam failures, design of flood defense structures, prevention measures and the environmental social, economic and forensic aspects related to the topic. Moreover, an exhaustive range of laboratory tests and modeling techniques is explored to deal effectively with shock waves and other disasters caused by dam failures. Disaster management refers to programs and strategies designed to prevent, mitigate, prepare for, respond to and recover from the effects of these phenomena.To manage and minimize these risks, it is necessary to identify hazards and vulnerability by means of a deep knowledge of the causes which drive to dam failures, and to understand the flow propagation process.Knowledge and advanced scientific tools play a role of paramount importance of coping with flooding and other dam-break problems along with capacity building in the context of political and administrative frameworks. All these aspects are featured in the book, which is a comprehensive treaty that covers the most theoretical and advanced aspects of structural and hydraulic engineering, together with the hazard assessment and mitigation measures and the social economic and forensic aspects related to subject.
Download or read book Biomimicry written by Janine M. Benyus and published by Harper Collins. This book was released on 2009-08-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Repackaged with a new afterword, this "valuable and entertaining" (New York Times Book Review) book explores how scientists are adapting nature's best ideas to solve tough 21st century problems. Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes readers into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; harness energy by examining how a leaf converts sunlight into fuel in trillionths of a second; and many more examples. Composed of stories of vision and invention, personalities and pipe dreams, Biomimicry is must reading for anyone interested in the shape of our future.
Download or read book Lemur Social Systems and Their Ecological Basis written by J. Ganzhorn and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has seen a steady increase in studies oflemur behavior and ecology. As a result, there is much novel information on newly studied populations, and even newly discovered species, that has not yet been published or summarized. In fact, lemurs have not been the focus of an international symposium since the Prosimian Biology Conference in London in 1972. Moreover, research on lemurs has reached a new quality by addressing general issues in behavioral ecology and evolutionary biology. Although lemurs provide important comparative information on these topics, this aspect of research on lemurs has not been reviewed and compared with similar studies in other primate radiations. Thus, as did many in the field, we felt that the time was ripe to review and synthesize our knowledge of lemur behavioral ecology. Following an initiative by Gerry Doyle, we organized a symposium at the XIVth Congress of the International Primatological Society in Strasbourg, France, where 15 contributions summarized much new information on lemur social systems and their ecological basis. This volume provides a collection of the papers presented at the Strasbourg symposium (plus two reports from recently completed field projects). Each chapter was peer-reviewed, typically by one "lemurologist" and one other biologist. The first three chapters present novel information from the first long-term field studies of three enigmatic species. Sterling describes the social organization of Daubentonia madagascariensis, showing that aye-aye ranging patterns deviate from those of all other nocturnal primates.

Download or read book Historical Dictionary of Pakistan written by Shahid Javed Burki and published by . This book was released on 1999 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pakistan is unlike most other countries in the emerging world. It is one of the two nations – the other being the state of Israel – founded on the basis of religion. Although it was created to provide a homeland for the Muslim community of British India, in its original form it was able to accommodate only about half of the people of Islamic faith who lived in the subcontinent. Pakistan’s birth in 1947 resulted in one of the largest movements of people in human history when some 14 million people left their homes, with 8 million Muslims leaving India for what is now Pakistan and 6 million Hindus and Sikhs moving in the opposite direction. This was the first large-scale incidence of ethnic cleansing the world was to witness. --

Download or read book Unidentified written by Robert Salas and published by Career Press. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1969 the U.S. Air Force issued a statement that read' "No UFO reported, investigated and evaluated by the Air Force was ever an indication of threat to our national security." This statement is patently false. It has been proven untrue by the testimony of many military officers and airmen and documentation of incidents involving UFOs and nuclear weapons, testimonies of which the U.S. Air Force was fully aware. Unidentified details many of these testimonies, some for the first time. As partial justification for its position, the Air Force cites a University of Colorado study that was contracted and paid for by federal funds. Unidentified reveals how this study was actually just another part of the plan to cover up the reality of the UFO phenomenon. For the first time, Unidentified publishes evidence that the investigators for the Colorado study knew about the UFO-related missile shutdown incidents but did not investigate them or include them in their final report.
