This book was released on 1998 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les applications " Grand Challenge " nécessitent une puissance de calcul très importante. Malgré la haute performance des outils informatiques engendrée par la haute intégration des circuits électroniques, la puissance requise par ces applications, de l'ordre du tera-flops, reste non satisfaite. Le challenge pose a l'informaticien trouve sa solution dans la parallélisation de l'environnement de calcul. Celui-ci est constitué du calculateur, de l'algorithmique, du langage de programmation et de son compilateur. Mais l'environnement ne peut être efficace que s'il y a adéquation entre ces différentes composantes. Dans ce but, un environnement de programmation parallèle adapte au traitement d'images et au calcul scientifique est proposé dans cette thèse. Dans cette étude nous avons introduit le langage C// et son compilateur. Le langage C// est une extension parallèle du C basée sur le modèle de programmation a parallélisme de données. Le modèle d'exécution est de type SPMD à mémoire partagée et physiquement distribuée (DSM). Plusieurs processeurs de la machine exécutent le même programme et communiquent à travers des variables partagées. Des points de synchronisation sont utilisés par le programmeur pour coordonner les divers flots de la machine et maintenir la cohérence de données. L'atelier de compilation de C // se compose de deux phases consécutives. La première phase consiste en la traduction du code C // en code C après analyse syntaxique et sémantique des constructions parallèles relevant de notre paradigme de programmation. Ce code sera ensuite compilé par le compilateur Gcc de la FSF (Free Software Foundation) en code machine. L'utilité de Gcc provient de sa disponibilité, sa portabilité et sa configurabilité pour d'autres plates-formes. La machine symphonie nous a servi d'exemple pour la configuration de Gcc. Nous avons aussi implanté l'atelier de compilation sur la machine GFLOPS. Plusieurs applications relevant du domaine de traitement d'images ont été développées et simulées sur GFLOPS. Ceci nous a permis d'évaluer et de valider notre environnement de programmation C // sur cette machine. Les premiers résultats sont très encourageants.

Download or read book Water Heritage written by Willem Willems and published by . This book was released on 2017-01-15 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects

This book was released on 2017-11-30 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This joint venture between ICOMOS, the advisory body to UNESCO on cultural sites, and the International Astronomical Union is the second volume in an ongoing exploration of themes and issues relating to astronomical heritage in particular and to science and technology heritage in general. It examines a number of key questions relating to astronomical heritage sites and their potential recognition as World Heritage, attempting to identify what might constitute "outstanding universal value" in relation to astronomy. "Heritage Sites of Astronomy and Archaeoastronomy--Volume 2" represents the culmination of several years' work to address some of the most challenging issues raised in the first ICOMOS-IAU Thematic Study, published in 2010. These include the recognition and preservation of the value of dark skies at both cultural and natural sites and landscapes; balancing archaeoastronomical considerations in the context of broader archaeological and cultural values; the potential for serial nominations; and management issues such as preserving the integrity of astronomical sightlines through the landscape.Its case studies are developed in greater depth than those in volume 1, and generally structured as segments of draft nomination dossiers. They include seven-stone antas (prehistoric dolmens) in Portugal and Spain, the thirteen towers of Chankillo in Peru, the astronomical timing of irrigation in Oman, Pic du Midi de Bigorre Observatory in France, Baikonur Cosmodrome in Kazakhstan, and Aoraki-Mackenzie International Dark Sky Reserve in New Zealand. A case study on Stonehenge, already a World Heritage Site, focuses on preserving the integrity of the solstitial sightlines.As for the first ICOMOS-IAU Thematic Study, a international team of authors including historians, astronomers and heritage professionals is led by Professor Clive Ruggles for the IAU and Professor Michel Cotte for ICOMOS.

Download or read book The Study of Anosognosia written by George P. Prigatano and published by Oxford University Press. This book was released on 2010-04-21 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of anosognosia has witnessed an unprecedented increase in interest over the last 20 years. This has resulted in numerous empirical investigations as well as theoretical writings on the nature of human consciousness and how disorders of the brain may influence the person's subjective awareness of a disturbed neurological or neuropsychological function. This edited text summarizes many of the advances that have taken place in the field of anosognosia. It reviews research findings on anosognosia for hemiplegia following stroke, Anton's syndrome, and a variety of disorders in which impaired self-awareness is common. It also provides suggestive guidelines for the management and rehabilitation of persons who have anosognosia or impaired self-awareness.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
