Download or read book Analyse des contenus audiovisuels : métalangage et modèles de description written by STOCKINGER Peter and published by Lavoisier. This book was released on 2012-09-05 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'enjeu majeur pour les bibliothèques et archives numériques d'aujourd'hui est de permettre à tout usager une appropriation active de leurs fonds textuels et plus particulièrement audiovisuels. L'appropriation active implique l'adaptation des données audiovisuelles aux besoins et intérêts spécifiques d'un utilisateur ou d'un groupe d'utilisateurs. Analyse des contenus audiovisuels propose une étude du métalangage de description. Cet ensemble de modèles fonctionnels est un outil sémantique nécessaire à l'analyse concrète et personnelle d'un corpus de textes audiovisuels documentant l'univers du discours d'une archive audiovisuelle. Cet ouvrage dresse en premier lieu le cadre théorique et méthodologique de référence qui est celui de la sémiotique du texte audiovisuel. Les deux parties suivantes développent d'une manière détaillée et concrète, le travail de l'analyste d'un corpus audiovisuel à l'aide d'un métalangage de description. Enfin, les différents éléments métalinguistiques qui le composent sont analysés.
Book Synopsis Environmental Fluid Mechanics - Méchanique des Fluides Environnementaux by : CIGB ICOLD
Download or read book Environmental Fluid Mechanics - Méchanique des Fluides Environnementaux written by CIGB ICOLD and published by CRC Press. This book was released on 2022-10-28 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dams are planned, constructed, and operated to meet human needs - generation of energy, irrigated agricultural production, flood control, public and industrial supply, supply of drinking water, and various other purposes. Dams impound water in reservoirs during times of high flood that can be used for human requirements during times with inadequate natural flows. Positive impacts of dams are improved flood control, improved welfare resulting from new access to irrigation and drinking water. Without dams there would be insufficient food to feed the world’s people and energy would be generated by burning fossil fuels that produce greenhouse gases. Despite this progress there remain significant concerns about the environmental impacts of dams. These environmental impacts are complex and far reaching, remote of the dam, and may occur in time with the dam construction or later and may lead to a loss of biodiversity and of productivity of natural resources. This bulletin compiles improvements in knowledge and state of the art technology to avoid or mitigate environmental impacts of dams on the natural ecosystem as well as to the people that depend upon them for their livelihood and also addresses the mitigation of environmental impacts on dams and reservoirs. Les barrages sont planifiés, construits et exploités de manière à répondre aux besoins humains. Les barrages retiennent l'eau dans les réservoirs pendant les périodes de forte crue, une eau qui peut être utilisée pour les besoins de l'homme pendant les périodes d’insuffisance des débits naturels. Les impacts positifs de barrages sont le contrôle des crues et l'amélioration du bien-être résultant du nouvel accès à l'irrigation et à l'eau potable. Sans barrages, la production alimentaire serait insuffisante pour nourrir la population du globe et l'énergie serait générée en brûlant des combustibles fossiles qui produisent des gaz à effet de serre. Malgré ces progrès, d'importantes préoccupations subsistent quant aux retombées des barrages sur l’environnement. Les impacts environnementaux sont complexes et d’une grande portée. Ils peuvent se produire au moment de la construction du barrage ou plus tard et peuvent entraîner une perte de la biodiversité et de la productivité des ressources naturelles. Le présent bulletin compile l'amélioration des connaissances et des technologies les plus récentes pour éviter ou atténuer les impacts environnementaux des barrages sur l'écosystème naturel ainsi que pour les personnes qui en dépendent pour leur subsistance. Il aborde également l'atténuation des impacts environnementaux sur les barrages et les réservoirs.
Book Synopsis Spatial Database Transfer Standards by : H. Moellering
Download or read book Spatial Database Transfer Standards written by H. Moellering and published by Elsevier. This book was released on 2013-10-22 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1960's individuals and organisations throughout the world have been building geographic databases used in conjunction with geographic hardware and software systems to collect, analyse, display and archive digital data. Through the years it was recognised that efficiencies could be gained if the geographic database built by one group could be used by multiple users across different computer systems and formats. Therefore, it was acknowledged that spatial database transfer standards were needed to facilitate the exchange and transfer of digital geographic data.Throughout the 1980's several organisations worldwide began working on the problem of producing spatial database transfer standards. As this work was initiated, research workers began to informally compare notes and developments. The International Cartographic Association [ICA], recognising the worldwide importance of standards, organised a Standards Working Group. The initial goal of this working group was to produce a monograph reporting on the present state of development in digital database transfer standards.This book is a unique collection of reports by individual nations and international organisations that describe existing geographic standards and summarize efforts to develop geographic database transfer standards worldwide.

Available in PDF, EPUB and Kindle. Book excerpt: L’émergence des systèmes de transport intelligents est due principalement aux grands progrès technologiques dans les domaines des protocoles de communication sans fil, des systèmes embarqués et temps réel. Très prometteurs, ces derniers permettront d’offrir un large éventail de nouvelles applications, de nouveaux véhicules communicants et de définir un éco-système de mobilités diversifiées. Les caractéristiques inhérentes à ces systèmes posent de nouveaux challenges en termes de protocoles et d’architectures de communications. Les réseaux véhiculaires connaissent des évolutions récentes : cet ouvrage propose d’en traiter les problèmes critiques, à savoir le contrôle de congestion, le routage, le clustering, l’interconnexion entre le réseau véhiculaire et les réseaux LTE/LTE Advanced, le contrôle du trafic routier ou encore la simulation à travers les outils et la génération de traces de mobilité. D’approche analytique, cet ouvrage se présente comme la genèse d’un nouveau domaine qui est en train de bouleverser les modèles de transports dans nos sociétés.
Book Synopsis The Econometrics of Panel Data by : László Mátyás
Download or read book The Econometrics of Panel Data written by László Mátyás and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 944 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to provide a general overview of the econometrics of panel data, both from a theoretical and from an applied viewpoint. Since the pioneering papers by Edwin Kuh (1959), Yair Mundlak (1961), Irving Hoch (1962), and Pietro Balestra and Marc Nerlove (1966), the pooling of cross sections and time series data has become an increasingly popular way of quantifying economic relationships. Each series provides information lacking in the other, so a combination of both leads to more accurate and reliable results than would be achievable by one type of series alone. Over the last 30 years much work has been done: investigation of the properties of the applied estimators and test statistics, analysis of dynamic models and the effects of eventual measurement errors, etc. These are just some of the problems addressed by this work. In addition, some specific diffi culties associated with the use of panel data, such as attrition, heterogeneity, selectivity bias, pseudo panels etc., have also been explored. The first objective of this book, which takes up Parts I and II, is to give as complete and up-to-date a presentation of these theoretical developments as possible. Part I is concerned with classical linear models and their extensions; Part II deals with nonlinear models and related issues: logit and pro bit models, latent variable models, duration and count data models, incomplete panels and selectivity bias, point processes, and simulation techniques.
