This book was released on 1989 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: DE NOMBREUX DOMAINES D'APPLICATIONS TELS QUE: LA CONCEPTION ASSISTEE PAR ORDINATEUR (CAO), LA PRODUCTION DE DOCUMENTS INCORPORANT TEXTES, IMAGES ET GRAPHIQUES, LE GENIE LOGICIEL, NECESSITENT UNE REPRESENTATION DIRECTE D'OBJETS COMPLEXES AINSI QUE LEUR MANIPULATION EFFICACE. L'APPROCHE ORIENTE-OBJET OFFRE DE NOMBREUX AVANTAGES POUR MODELISER TANT CES DOMAINES D'APPLICATION QUE LES TRAITEMENTS QUI LEUR SONT ASSOCIES. A L'AVENIR, LES SYSTEMES DE GESTION D'OBJETS DEVRONT FOURNIR LES FONCTIONNALITES NECESSAIRES POUR SUPPORTER DES MODELES DE DONNEES COMPLEXES. UNE DES CONTRAINTES ESSENTIELLE A RESPECTER EST L'INDEPENDANCE DES OBJETS. IL FAUT DONC METTRE EN UVRE DES TECHNIQUES DE STOCKAGE PERMETTANT DE REPARTIR LES OBJETS SUR DES SUPPORTS PHYSIQUES TOUT EN TENANT COMPTE DES LIENS LOGIQUES QUI LES RELIENT. DANS CE CADRE, DE BONNES STRATEGIES DE REGROUPEMENT S'AVERENT ETRE CRUCIALES AFIN D'AUGMENTER LES PERFORMANCES DE CES SYSTEMES. DANS CETTE THESE, NOUS DEFINISSONS DES STRATEGIES DE REGROUPEMENT ET PRESENTONS UN ALGORITHME DE REGROUPEMENT D'OBJETS SUR DISQUE. NOUS DEVELOPPONS, ENSUITE, UN MODELE DE COUT DESTINE A EVALUER LA QUALITE DE CHAQUE STRATEGIE. CE MODELE DE COUT NOUS PERMETTANT ALORS DE DERIVER AUTOMATIQUEMENT, EN UN TEMPS LINEAIRE, DE NOUVELLES STRATEGIES DE REGROUPEMENT. UN ENSEMBLE DE MESURES A ETE DEVELOPPE, CES MESURES NOUS PERMETTANT DE VALIDER LA PORTEE DU MODELE DECRIT

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.

Available in PDF, EPUB and Kindle. Book excerpt: Theoretical and Applied Solutions in Multi Scale Mapping Users have come to expect instant access to up-to-date geographical information, with global coverage--presented at widely varying levels of detail, as digital and paper products; customisable data that can readily combined with other geographic information. These requirements present an immense challenge to those supporting the delivery of such services (National Mapping Agencies (NMA), Government Departments, and private business. Generalisation of Geographic Information: Cartographic Modelling and Applications provides detailed review of state of the art technologies associated with these challenges, including the most recent developments in cartometric analysis techniques able to support high levels of automation among multi scale derivation techniques. The book illustrates the application of these ideas within existing and emerging technologies. In addition to providing a comprehensive theoretical underpinning, the book demonstrates how theoretical developments have translated into commercial systems deployed within NMAs. The book explores relevance of open systems in support of collaborative research and open source web based map services. State of the art review on multi scale representation techniques Detailed consideration of database requirements and object modeling in support of emerging applications (3D, mobile) and innovative delivery (map generalisation services) Illustration through existing map production environment implementations Consolidated bibliography (680 entries), 200 illustrations, author and subject index

This book was released on 2014-02-26 with total page 327 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Web Cartography written by Jan-Menno Kraak and published by CRC Press. This book was released on 2003-09-02 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maps and atlases are created as soon as information on our geography has been clarified. They are used to find directions or to get insight into spatial relations. They are produced and used both on paper as well as on-screen. The Web is the new medium for spreading and using maps. This book explains the benefits of this medium from the perspective of the user, and the map provider. Opportunities and pitfalls are illustrated by a set of case-studies. A website accompanies the book and provides a dynamic environment for demonstrating many of the principles set out in the text, including access to a basic course in Internet cartography as well as links to other interesting places on the Web. Professor Kraak looks at basic questions such as "I have this data what can I do with it?" and discusses the various functions of maps on the web. Web Cartography also looks at the particularities of multidimensional web maps and addresses topics such as map contents (colour, text and symbols), map physics (size and resolution), and the map environment (interface design/site contents).

Download or read book Cognition in the Wild written by Edwin Hutchins and published by MIT Press. This book was released on 1996-08-26 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edwin Hutchins combines his background as an anthropologist and an open ocean racing sailor and navigator in this account of how anthropological methods can be combined with cognitive theory to produce a new reading of cognitive science. His theoretical insights are grounded in an extended analysis of ship navigation—its computational basis, its historical roots, its social organization, and the details of its implementation in actual practice aboard large ships. The result is an unusual interdisciplinary approach to cognition in culturally constituted activities outside the laboratory—"in the wild." Hutchins examines a set of phenomena that have fallen in the cracks between the established disciplines of psychology and anthropology, bringing to light a new set of relationships between culture and cognition. The standard view is that culture affects the cognition of individuals. Hutchins argues instead that cultural activity systems have cognitive properties of their own that are different from the cognitive properties of the individuals who participate in them. Each action for bringing a large naval vessel into port, for example, is informed by culture: the navigation team can be seen as a cognitive and computational system. Introducing Navy life and work on the bridge, Hutchins makes a clear distinction between the cognitive properties of an individual and the cognitive properties of a system. In striking contrast to the usual laboratory tasks of research in cognitive science, he applies the principal metaphor of cognitive science—cognition as computation (adopting David Marr's paradigm)—to the navigation task. After comparing modern Western navigation with the method practiced in Micronesia, Hutchins explores the computational and cognitive properties of systems that are larger than an individual. He then turns to an analysis of learning or change in the organization of cognitive systems at several scales. Hutchins's conclusion illustrates the costs of ignoring the cultural nature of cognition, pointing to the ways in which contemporary cognitive science can be transformed by new meanings and interpretations.

Download or read book Divine Names on the Spot written by Fabio Porzia and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Ancient Greek and Semitic languages resorted to a large range of words to name the divine. Gods and goddesses were called by a variety of names and combinations of onomastic attributes. This broad lexicon of names is characterised by plurality and a tendency to build on different sequences of names; therefore, the Mapping Ancient Polytheisms project focuses on the process of naming the divine in order to better understand the ancient divine in terms of a plurality in the making. A fundamental rule for reading ancient divine names is to grasp them in their context - time and place, a ritual, the form of the discourse, a cultural milieu...: a deity is usually named according to a specific situation. From Artemis Eulochia to al-Lat, al-'Uzza and Manat, from Melqart to "my rock" in the biblical book of Psalms, this volume journeys between the sanctuary on Mount Gerizim and late antique magical practices, revisiting rituals, hymnic poetry, oaths of orators and philosophical prayers. While targeting different names in different contexts, the contributors draft theoretical propositions towards a dynamic approach of naming the divine in antiquity.'

Book excerpt: This book examines a new trend affecting cartography and geographic information science. Presenting the work of over 30 authors from 16 different countries, the book provides an overview of current research in the new area of Internet Cartography. Chapters deal with the growth of this form of map distribution, uses in education, privacy issues, and technical aspects from the point of view of the map provider - including Internet protocols such as XML and SVG. Many see the Internet as a revolution for cartography. Previously tied to the medium of paper and expensive large-format color print technology, maps had a limited distribution and use. The Internet made it possible to not only distribute maps to a much larger audience but also to incorporate interaction and animation in the display. Maps have also become timelier with some maps of traffic and weather being updated every few minutes. In addition, it is now possible to access maps from servers throughout the world. Finally, the Internet has made historic maps available for viewing to the public that were previously only available in map libraries with limited access. * Provides comprehensive coverage of maps and the internet * Delivers a global perspective * Combines theoretical and practical aspects
