Available in PDF, EPUB and Kindle. Book excerpt: Les systèmes temps réel sont des systèmes informatiques composés de tâches auxquelles sont associées des contraintes temporelles, appelées échéances. Dans notre étude, nous distinguons deux familles de tâches : les tâches temps réel dur et les tâches temps réel souple. Les premières possèdent une échéance stricte, qu'elles doivent impérativement respecter. Elles sont de nature périodique, ou sporadique, et l'étude analytique de leur comportement fait l'objet d'un état de l'art conséquent. Les secondes sont de nature apériodique. Aucune hypothèse sur leur modèle d'arrivéée ni sur leur nombre n'est possible. Aucune garantie ne saurait être donnée sur leur comportement dès lors que l'on ne peut écarter les situations de surcharge, où la demande de calcul peut dépasser les capacités du système. La problématique devient alors l'étude des solutions d'ordonnancement mixte de tâches périodiques et apériodiques qui minimisent les temps de réponse des tâches apériodiques tout en garantissant les échéances des tâches périodiques. De nombreuses solutions ont été proposées ces vingt dernières années. On distingue les solutions basées sur la réservation de ressources, les serveurs de tâches, des solutions exploitant les instants d'inactivité du système, comme les algorithmes de vol de temps creux. La spécification Java pour le temps réel (RTSJ) voit le jour dans les années 2000. Si cette norme répond à de nombreux problèmes liés à la gestion de la mémoire ou à l'ordonnancement des tâches périodiques, celui de l'ordonnancement mixte de tâches périodiques et apériodiques n'est pas abordé. Nous proposons dans cette thèse d'apporter les modifications nécessaires aux algorithmes principaux d'ordonnancement mixte, le Polling Server (PS), le Deferrable Server (DS) et le Dynamic Approximate Slack Stealer (DASS) en vue de leur implantation avec RTSJ. Ces algorithmes ne peuvent en effet être implantés directement tels qu'ils sont décrits, car ils sont trop liés à l'ordonnanceur du système. Nous proposons des extensions aux APIs RTSJ existantes pour faciliter l'implantation de ces mécanismes modifiés, et nous fournissons les interfaces utiles à l'ajout d'autres solutions algorithmiques. Nous proposons également des modifications sur les APIs existantes de RTSJ afin de répondre aux problèmes d'intégration et d'implantation d'algorithmes d'analyse de faisabilité. Nous proposons enfin un algorithme d'estimation des temps creux, le Minimal Approximate Slack Stealer (MASS), dont l'implantation au niveau utilisateur, permet son intégration dans RTSJ.

Book excerpt: Le terme promotion de la santé en Afrique, près de 30 ans après l'adoption de la Charte d'Ottawa, continue d'avoir des connotations complètement hors du sens que lui confère cette charte. Cela n'est pas étonnant quand on sait que la notion de santé dans ce contexte africain équivaut à la lutte contre la maladie à travers les soins de santé dispensés par des professionnels de la santé dans des formations sanitaires et les hôpitaux. L'évolution que connait le continent depuis quelques décennies est de donner un peu plus de place à la communauté à travers les relais communautaires dans une participation communautaire vidée de son contenu, car le pouvoir n'est jamais passé entre les mains des communautés.C'est au vu de tout ceci que le présent ouvrage à sa raison d'être pour expliquer les fondements de l'autonomisation communautaire et de la promotion de la santé avec leur importance pour la région africaine en proie aux mauvais indicateurs de santé comparativement aux autres régions du monde.

Available in PDF, EPUB and Kindle. Book excerpt: This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This edited collection of articles addresses aspects of medical care in which human error is associated with unanticipated adverse outcomes. For the purposes of this book, human error encompasses mismanagement of medical care due to: * inadequacies or ambiguity in the design of a medical device or institutional setting for the delivery of medical care; * inappropriate responses to antagonistic environmental conditions such as crowding and excessive clutter in institutional settings, extremes in weather, or lack of power and water in a home or field setting; * cognitive errors of omission and commission precipitated by inadequate information and/or situational factors -- stress, fatigue, excessive cognitive workload. The first to address the subject of human error in medicine, this book considers the topic from a problem oriented, systems perspective; that is, human error is considered not as the source of the problem, but as a flag indicating that a problem exists. The focus is on the identification of the factors within the system in which an error occurs that contribute to the problem of human error. As those factors are identified, efforts to alleviate them can be instituted and reduce the likelihood of error in medical care. Human error occurs in all aspects of human activity and can have particularly grave consequences when it occurs in medicine. Nearly everyone at some point in life will be the recipient of medical care and has the possibility of experiencing the consequences of medical error. The consideration of human error in medicine is important because of the number of people that are affected, the problems incurred by such error, and the societal impact of such problems. The cost of those consequences to the individuals involved in medical error, both in the health care providers' concern and the patients' emotional and physical pain, the cost of care to alleviate the consequences of the error, and the cost to society in dollars and in lost personal contributions, mandates consideration of ways to reduce the likelihood of human error in medicine. The chapters were written by leaders in a variety of fields, including psychology, medicine, engineering, cognitive science, human factors, gerontology, and nursing. Their experience was gained through actual hands-on provision of medical care and/or research into factors contributing to error in such care. Because of the experience of the chapter authors, their systematic consideration of the issues in this book affords the reader an insightful, applied approach to human error in medicine -- an approach fortified by academic discipline.

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.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

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.
