This book was released on 1981-01-01T00:00:00+01:00 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Au cours des prochaines années, l'utilisation des systèmes informatiques répartis deviendra une des composantes essentielles de notre société. Le succès de leurs applications dépendra, étroitement, de la conception des systèmes de gestion des bases de données, réparties (SGBDR) en vue de leur bonne adaptation aux besoins des utilisateurs. C'est pourquoi les utilisateurs et les informaticiens doivent réfléchir, dès maintenant, aux problèmes que pose la conception de ces nouveaux systèmes. Le but de ce livre, actuellement unique en son genre en langue française, est d'aider les uns et les autres dans cette tâche. Il propose une analyse détaillée et progressive, en vue d'identifier les problèmes et de choisir les solutions, qui jalonnent le processus de la conception d'un SGBDR. Il permet de comprendre les principes de base de ces systèmes, et d'en connaître, précisément et complètement, les possibilités fonctionnelles. Cette analyse privilégie, en effet, l'étude des interactions entre les besoins des utilisateurs et les spécifications du système : c'est dans la conformité de celles-ci à ceux-là, plus que dans les processus techniques, que se joue l'avenir de cette informatique. L'ouvrage s'adresse donc à la fois aux utilisateurs, auxquels la clarté de la rédaction le rend facilement accessible, aux ingénieurs qui ont à évaluer l'apport de ces nouvelles techniques, aux informaticiens, qui auront à concevoir des systèmes répartis, et aux chercheurs qui veulent s'initier à ce domaine de l'informatique. Les principaux points abordés par l'auteur sont les suivants : - pourquoi recourir à l'informatique répartie ? - qu'est-ce qu'un système de gestion de bases de données réparties ? - définition de l'environnement réparti et de l'environnement local ; - définition du schéma global d'un SGBDR ; - la répartition des données ; - l'architecture du système, les différentes fonctions ; - les utilisateurs face à la répartition. L'ouvrage est complété par deux chapitres, l'un sur les tendances actuelles de la recherche, l'autre sur les conséquences de l'informatique répartie sur la vie des entreprises, sur les libertés individuelles et sur le développement de l'informatique.

This book was released on 1988 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nous nous proposons d'introduire un outil de gestion de bases de données pour la CAO. Les informations circulant dans un processus de conception peuvent être classées en deux bases de données : la base de données projet et la base de données de connaissances. Les informations modélisées concernent essentiellement la base de données projet : dans ce but est défini un système BD-CAO, appelé encore modèle, composé d'un modèle de données orienté-objet et d'un ensemble d'opérations s'appliquant sur ce modèle de données. Ce système BD-CAO permet d'exprimer pour les objets de conception, contraintes sur ces objets et des liens entre eux. Il possède des fonctionnalités adaptées à la CAO : conception ascendante, descendante et imbriquée, déduction, dynamicité de la structure, propriétés calculées, gestion d'objets incohérents ou incomplets. Nous étudions le cadre d'utilisation du modèle par l'intermédiaire d'exemples de conception dans le domaine de la mécanique puis nous définissons le dialogue par l'intermédiaire de deux propositions d'interfaces. Une maquette de ce système BD-CAO est en cours de réalisation

Download or read book Global Burden of Disease and Risk Factors written by Alan D. Lopez and published by World Bank Publications. This book was released on 2006-04-02 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strategic health planning, the cornerstone of initiatives designed to achieve health improvement goals around the world, requires an understanding of the comparative burden of diseases and injuries, their corresponding risk factors and the likely effects of invervention options. The Global Burden of Disease framework, originally published in 1990, has been widely adopted as the preferred method for health accounting and has become the standard to guide the setting of health research priorities. This publication sets out an updated assessment of the situation, with an analysis of trends observed since 1990 and a chapter on the sensitivity of GBD estimates to various sources of uncertainty in methods and data.

Book excerpt: "Your Mindful Compass" takes us behind the emotional curtain to see the mechanisms regulating individuals in social systems. There is great comfort and wisdom in knowing we can increase our awareness to manage the swift and ancient mechanisms of social control. We can gain greater flexibility by seeing how social controls work in systems from ants to humans. To be less controlled by others, we learn how emotional systems influence our relationship-oriented brain. People want to know what goes on in families that give rise to amazing leaders and/or terrorists. For the first time in history we can understand the systems in which we live. The social sciences have been accumulating knowledge since the early fifties as to how we are regulated by others. S. Milgram, S. Ashe, P. Zimbardo and J. Calhoun, detail the vulnerability to being duped and deceived and the difficulty of cooperating when values differ. Murray Bowen, M.D., the first researcher to observe several live-in families, for up to three years, at the National Institute of Mental Health. Describing how family members overly influence one another and distribute stress unevenly, Bowen described both how symptoms and family leaders emerge in highly stressed families. Our brain is not organized to automatically perceive that each family has an emotional system, fine-tuned by evolution and "valuing" its survival as a whole, as much as the survival of any individual. It is easier to see this emotional system function in ants or mice but not in humans. The emotional system is organized to snooker us humans: encouraging us to take sides, run away from others, to pressure others, to get sick, to blame others, and to have great difficulty in seeing our part in problems. It is hard to see that we become anxious, stressed out and even that we are difficult to deal with. But "thinking systems" can open the doors of perception, allowing us to experience the world in a different way. This book offers both coaching ideas and stories from leaders as to strategies to break out from social control by de-triangling, using paradoxes, reversals and other types of interruptions of highly linked emotional processes. Time is needed to think clearly about the automatic nature of the two against one triangle. Time and experience is required as we learn strategies to put two people together and get self outside the control of the system. In addition, it takes time to clarify and define one's principles, to know what "I" will or will not do and to be able to take a stand with others with whom we are very involved. The good news is that systems' thinking is possible for anyone. It is always possible for an individual to understand feelings and to integrate them with their more rational brains. In so doing, an individual increases his or her ability to communicate despite misunderstandings or even rejection from important others. The effort involved in creating your Mindful Compass enables us to perceive the relationship system without experiencing it's threats. The four points on the Mindful Compass are: 1) Action for Self, 2) Resistance to Forward Progress, 3) Knowledge of Social Systems and the 4) The Ability to Stand Alone. Each gives us a view of the process one enters when making an effort to define a self and build an emotional backbone. It is not easy to find our way through the social jungle. The ability to know emotional systems well enough to take a position for self and to become more differentiated is part of the natural way humans cope with pressure. Now people can use available knowledge to build an emotional backbone, by thoughtfully altering their part in the relationship system. No one knows how far one can go by making an effort to be more of a self-defined individual in relationships to others. Through increasing emotional maturity, we can find greater individual freedom at the same time that we increase our ability to cooperate and to be close to others.

Book excerpt: "Science - "empirical knowledge" - and technology - "applied science" - have long played a key role in social development. In modern times they have come to be seen as absolutely essential factors in the achievement of economic growth and development. And though many dispute their ascendancy and legitimately point to their abuses, there is no escaping their presence and impact." "Taking as a main theme the central role of science and technology in economic progress, this first-of-a-kind sourcebook gathers together the perspectives and expertise of an international body of specialists in science and technology policy to examine the role of science and technology in development, and assess their social, economic, and political dimensions. The authors look at the key issues in relation to the exigencies of developing countries in the "new international context." They emphasize the complexity of the links between science, technology, and development and the important insights to be gained from the study of these links. The authors also point out that, despite science and technology's promise of social and economic progress, such progress is less than ever an inevitable result of their application - though there is no doubt about what can be achieved through science and technology, the quest is an uncertain one."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Download or read book The Mis Behaviour of Markets written by Benoit B. Mandelbrot and published by Profile Books. This book was released on 2010-10-01 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This international bestseller, which foreshadowed a market crash, explains why it could happen again if we don't act now. Fractal geometry is the mathematics of roughness: how to reduce the outline of a jagged leaf or static in a computer connection to a few simple mathematical properties. With his fractal tools, Mandelbrot has got to the bottom of how financial markets really work. He finds they have a shifting sense of time and wild behaviour that makes them volatile, dangerous - and beautiful. In his models, the complex gyrations of the FTSE 100 and exchange rates can be reduced to straightforward formulae that yield a much more accurate description of the risks involved.
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 Parallel Computing written by Roman Trobec and published by Springer Science & Business Media. This book was released on 2009-06-18 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of parallel programming and architectures is essential for simulating and solving problems in modern computational practice. There has been rapid progress in microprocessor architecture, interconnection technology and software devel- ment, which are in?uencing directly the rapid growth of parallel and distributed computing. However, in order to make these bene?ts usable in practice, this dev- opment must be accompanied by progress in the design, analysis and application aspects of parallel algorithms. In particular, new approaches from parallel num- ics are important for solving complex computational problems on parallel and/or distributed systems. The contributions to this book are focused on topics most concerned in the trends of today’s parallel computing. These range from parallel algorithmics, progr- ming, tools, network computing to future parallel computing. Particular attention is paid to parallel numerics: linear algebra, differential equations, numerical integ- tion, number theory and their applications in computer simulations, which together form the kernel of the monograph. We expect that the book will be of interest to scientists working on parallel computing, doctoral students, teachers, engineers and mathematicians dealing with numerical applications and computer simulations of natural phenomena.
