This book was released on 2006 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le thème de recherche de cette thèse concerne la conception et l’implantation d’un système de gestion de bases de données distribuées et scalables (ang. Scalable Distributed Database System, SD-DBS) que nous avons appelé SD-SQL Server. SD-SQL Server implémente une nouvelle architecture de SGBD relationnel. Une base de SD-SQL Server, dite base scalable, grandit par la partition dynamique, scalable et distribuée de ses tables, dites scalables aussi. La partition et son évolution sont invisibles de l’usager/application. A l’heure actuelle, SD-SQL Server est le seul SGBD à offrir cette possibilité à notre connaissance. Les autres SGBDs connus, n’offrent au mieux que le partitionnement statique, nécessitant des réorganisations périodiques globales. Leur maniement est en général complexe et peu apprecié des usagers. Nos tables scalables sont organisées en segments d’une structure de données distribuée et scalable (SDDS). Chaque segment est placé sur un nœud lié de SQL Server. A l’heure actuelle, SQL Server supporte 250 nœuds liés, permettant à une table scalable de croître autant. L'expansion dynamique résulte des éclatements de segments débordant leur capacité de stockage. Chaque éclatement est déclenché par une insertion, à l’origine du débordement. Tout éclatement crée un ou plusieurs nouveaux segments. Les segments sont cachés des usagers/applications derrière les vues supportant les mises à jour, dites images. Les images sont des vues partitionnées et distribuées de SQL Server dynamiquement ajustées. Les usagers/applications de tables scalables n’interfacent que les images ou les vues des images.

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.
Download or read book Registries for Evaluating Patient Outcomes written by Agency for Healthcare Research and Quality/AHRQ and published by Government Printing Office. This book was released on 2014-04-01 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: This User’s Guide is intended to support the design, implementation, analysis, interpretation, and quality evaluation of registries created to increase understanding of patient outcomes. For the purposes of this guide, a patient registry is an organized system that uses observational study methods to collect uniform data (clinical and other) to evaluate specified outcomes for a population defined by a particular disease, condition, or exposure, and that serves one or more predetermined scientific, clinical, or policy purposes. A registry database is a file (or files) derived from the registry. Although registries can serve many purposes, this guide focuses on registries created for one or more of the following purposes: to describe the natural history of disease, to determine clinical effectiveness or cost-effectiveness of health care products and services, to measure or monitor safety and harm, and/or to measure quality of care. Registries are classified according to how their populations are defined. For example, product registries include patients who have been exposed to biopharmaceutical products or medical devices. Health services registries consist of patients who have had a common procedure, clinical encounter, or hospitalization. Disease or condition registries are defined by patients having the same diagnosis, such as cystic fibrosis or heart failure. The User’s Guide was created by researchers affiliated with AHRQ’s Effective Health Care Program, particularly those who participated in AHRQ’s DEcIDE (Developing Evidence to Inform Decisions About Effectiveness) program. Chapters were subject to multiple internal and external independent reviews.

Download or read book Rhythms of the Brain written by G. Buzsáki and published by Oxford University Press. This book was released on 2011 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of mechanisms in the brain that allow complicated things to happen in a coordinated fashion have produced some of the most spectacular discoveries in neuroscience. This book provides eloquent support for the idea that spontaneous neuron activity, far from being mere noise, is actually the source of our cognitive abilities. It takes a fresh look at the coevolution of structure and function in the mammalian brain, illustrating how self-emerged oscillatory timing is the brain's fundamental organizer of neuronal information. The small-world-like connectivity of the cerebral cortex allows for global computation on multiple spatial and temporal scales. The perpetual interactions among the multiple network oscillators keep cortical systems in a highly sensitive "metastable" state and provide energy-efficient synchronizing mechanisms via weak links. In a sequence of "cycles," György Buzsáki guides the reader from the physics of oscillations through neuronal assembly organization to complex cognitive processing and memory storage. His clear, fluid writing-accessible to any reader with some scientific knowledge-is supplemented by extensive footnotes and references that make it just as gratifying and instructive a read for the specialist. The coherent view of a single author who has been at the forefront of research in this exciting field, this volume is essential reading for anyone interested in our rapidly evolving understanding of the brain.

Bainbridge In the early decades of the 21st century, concentrated efforts can unify science based on the unity of nature, thereby advancing the combination of nanotechnology, biotechnology, information technology, and new technologies based in cognitive science. With proper attention to ethical issues and societal needs, converging in human abilities, societal technologies could achieve a tremendous improvement outcomes, the nation's productivity, and the quality of life. This is a broad, cross cutting, emerging and timely opportunity of interest to individuals, society and humanity in the long term. The phrase "convergent technologies" refers to the synergistic combination of four major "NBIC" (nano-bio-info-cogno) provinces of science and technology, each of which is currently progressing at a rapid rate: (a) nanoscience and nanotechnology; (b) biotechnology and biomedicine, including genetic engineering; (c) information technology, including advanced computing and communications; (d) cognitive science, including cognitive neuroscience. Timely and Broad Opportunity. Convergence of diverse technologies is based on material unity at the nanoscale and on technology integration from that scale.

Download or read book Wearable Robots written by José L. Pons and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wearable robot is a mechatronic system that is designed around the shape and function of the human body, with segments and joints corresponding to those of the person it is externally coupled with. Teleoperation and power amplification were the first applications, but after recent technological advances the range of application fields has widened. Increasing recognition from the scientific community means that this technology is now employed in telemanipulation, man-amplification, neuromotor control research and rehabilitation, and to assist with impaired human motor control. Logical in structure and original in its global orientation, this volume gives a full overview of wearable robotics, providing the reader with a complete understanding of the key applications and technologies suitable for its development. The main topics are demonstrated through two detailed case studies; one on a lower limb active orthosis for a human leg, and one on a wearable robot that suppresses upper limb tremor. These examples highlight the difficulties and potentialities in this area of technology, illustrating how design decisions should be made based on these. As well as discussing the cognitive interaction between human and robot, this comprehensive text also covers: the mechanics of the wearable robot and it’s biomechanical interaction with the user, including state-of-the-art technologies that enable sensory and motor interaction between human (biological) and wearable artificial (mechatronic) systems; the basis for bioinspiration and biomimetism, general rules for the development of biologically-inspired designs, and how these could serve recursively as biological models to explain biological systems; the study on the development of networks for wearable robotics. Wearable Robotics: Biomechatronic Exoskeletons will appeal to lecturers, senior undergraduate students, postgraduates and other researchers of medical, electrical and bio engineering who are interested in the area of assistive robotics. Active system developers in this sector of the engineering industry will also find it an informative and welcome resource.

Available in PDF, EPUB and Kindle. Book excerpt: th CAiSE 2004 was the 16 in the series of International Conferences on Advanced Information Systems Engineering. In the year 2004 the conference was hosted by the Faculty of Computer Science and Information Technology, Riga Technical University, Latvia. Since the late 1980s, the CAiSE conferences have provided a forum for the presentation and exchange of research results and practical experiences within the ?eld of Information Systems Engineering. The conference theme of CAiSE 2004 was Knowledge and Model Driven Information Systems Engineering for Networked Organizations. Modern businesses and IT systems are facing an ever more complex en- ronment characterized by openness, variety, and change. Organizations are - coming less self-su?cient and increasingly dependent on business partners and other actors. These trends call for openness of business as well as IT systems, i.e. the ability to connect and interoperate with other systems. Furthermore, organizations are experiencing ever more variety in their business, in all c- ceivable dimensions. The di?erent competencies required by the workforce are multiplying. In the same way, the variety in technology is overwhelming with a multitude of languages, platforms, devices, standards, and products. Moreover, organizations need to manage an environment that is constantly changing and where lead times, product life cycles, and partner relationships are shortening. ThedemandofhavingtoconstantlyadaptITtochangingtechnologiesandbu- ness practices has resulted in the birth of new ideas which may have a profound impact on the information systems engineering practices in future years, such as autonomic computing, component and services marketplaces and dynamically generated software.

Available in PDF, EPUB and Kindle. Book excerpt: A classroom-tested textbook providing a fundamental understandingof basic kinetic processes in materials This textbook, reflecting the hands-on teaching experience of itsthree authors, evolved from Massachusetts Institute of Technology'sfirst-year graduate curriculum in the Department of MaterialsScience and Engineering. It discusses key topics collectivelyrepresenting the basic kinetic processes that cause changes in thesize, shape, composition, and atomistic structure of materials.Readers gain a deeper understanding of these kinetic processes andof the properties and applications of materials. Topics are introduced in a logical order, enabling students todevelop a solid foundation before advancing to more sophisticatedtopics. Kinetics of Materials begins with diffusion, offering adescription of the elementary manner in which atoms and moleculesmove around in solids and liquids. Next, the more complex motion ofdislocations and interfaces is addressed. Finally, still morecomplex kinetic phenomena, such as morphological evolution andphase transformations, are treated. Throughout the textbook, readers are instilled with an appreciationof the subject's analytic foundations and, in many cases, theapproximations commonly used in the field. The authors offer manyextensive derivations of important results to help illuminate theirorigins. While the principal focus is on kinetic phenomena incrystalline materials, select phenomena in noncrystalline materialsare also discussed. In many cases, the principles involved apply toall materials. Exercises with accompanying solutions are provided throughoutKinetics of Materials, enabling readers to put their newfoundknowledge into practice. In addition, bibliographies are offeredwith each chapter, helping readers to investigate specializedtopics in greater detail. Several appendices presenting importantbackground material are also included. With its unique range of topics, progressive structure, andextensive exercises, this classroom-tested textbook provides anenriching learning experience for first-year graduate students.
