This book was released on 1992 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: LE COUT DU CONTROLE D'INTEGRITE SEMANTIQUE DANS LES SGBD RELATIONNELS EST UN COUT ADDITIONNEL AU COUT DE LA MISE A JOUR DE LA BASE. L'APPROCHE PRESENTEE DANS CETTE ETUDE CONSISTE A EXPLOITER LE CONCEPT DE TABLE DE DECISION POUR L'OPTIMISATION DU COUT DU CONTROLE ET EVENTUELLEMENT POUR TROUVER DES SOLUTIONS POUR LE CALCUL DE L'ENSEMBLE MINIMAL DES CONTRAINTES AINSI QUE POUR LA DETECTION, S'IL Y A LIEU, DE LEUR INCONSISTANCE. UNE CONTRAINTE D'INTEGRITE SEMANTIQUE EST UNE FORMULE DANS LE CALCUL RELATIONNEL A VARIABLES TUPLES, FERMEE ET MISE SOUS FORME NORMALE PRENEXE DISJONCTIVE. NOUS PARTAGEONS LES CONTRAINTES EN DEUX CLASSES: LES CONTRAINTES ELEMENTAIRES (DEFINIES SUR UNE SEULE RELATION ET DEVANT ETRE VERIFIEES PAR CHAQUE TUPLE DANS LA RELATION) ET LES CONTRAINTES GENERALES (TOUS LES AUTRES TYPES DE CONTRAINTES). L'ENSEMBLE DES CONTRAINTES ELEMENTAIRES DEFINIES SUR UNE MEME RELATION DE BASE EST REPRESENTE A PARTIR D'UNE STRUCTURE DE TABLE DE DECISION ET PEUVENT ETRE AINSI EVALUEES SANS ACCES A LA BASE. CETTE REPRESENTATION A PERMIS DE TROUVER DES SOLUTIONS POUR LE CALCUL DE L'ENSEMBLE MINIMAL AINSI QUE POUR LA DETECTION DE L'INCONSISTANCE DES CONTRAINTES. CES TRAITEMENTS AINSI QUE LE CONTROLE D'INTEGRITE SONT RAMENES A UN CALCUL DANS L'ALGEBRE DES VECTEURS BINAIRES. CONCERNANT LES CONTRAINTES GENERALES, NOUS MONTRONS QU'IL EST POSSIBLE DE DEFINIR UN INDEX QUI A LA STRUCTURE D'UNE TABLE DE DECISION ET QUI EST EXPLOITE POUR ACCELERER L'EVALUATION DES SELECTIONS. L'UTILISATION DES VECTEURS BINAIRES NOUS A ORIENTE VERS UNE METHODE DE JOINTURE QUI EST PERTINENTE POUR LE CONTROLE D'INTEGRITE ET QUI PERMET UNE PRISE EN COMPTE IMPLICITE DES QUANTIFICATEURS. CETTE METHODE UTILISE LES VECTEURS BINAIRES ET N'ABOUTIT PAS A LA CONSTRUCTION DE NOUVEAUX TUPLES. ENFIN, UNE SPECIFICATION DE L'IMPLANTATION DE CES METHODES DANS LE CADRE DU SGBDOO NICE-C++ EST PROPOSEE

Book Synopsis Water & Heritage by : Willem Willems
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

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.
Book Synopsis Cambridge Handbook of Engineering Education Research by : Aditya Johri
Download or read book Cambridge Handbook of Engineering Education Research written by Aditya Johri and published by Cambridge University Press. This book was released on 2014-02-10 with total page 1124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Handbook of Engineering Education Research is the critical reference source for the growing field of engineering education research, featuring the work of world luminaries writing to define and inform this emerging field. The Handbook draws extensively on contemporary research in the learning sciences, examining how technology affects learners and learning environments, and the role of social context in learning. Since a landmark issue of the Journal of Engineering Education (2005), in which senior scholars argued for a stronger theoretical and empirically driven agenda, engineering education has quickly emerged as a research-driven field increasing in both theoretical and empirical work drawing on many social science disciplines, disciplinary engineering knowledge, and computing. The Handbook is based on the research agenda from a series of interdisciplinary colloquia funded by the US National Science Foundation and published in the Journal of Engineering Education in October 2006.

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.

Book Synopsis Environmental Aspects of Dredging by : R. N. Bray
Download or read book Environmental Aspects of Dredging written by R. N. Bray and published by CRC Press. This book was released on 2008-03-10 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Expanding a port, deepening a navigation channel or creating new land for development, introduces changes to our physical, social, economic and political environment. Changes may result from events during the construction process, or relate to the nature of the completed structure. Changes can be positive or negative, short-term or long-term, and may affect the immediate vicinity of the project or a larger geographical area. Predicting and assessing all possible effects of a planned dredging activity in a scientifically-sound and reliable manner is essential, so that appropriate control measures can be taken to avoid or mitigate unwelcome impacts. This book provides guidance for a complete holistic environmental evaluation procedure and for the design and implementation of environmental control measures. The book is of particular interest to engineers, government agencies and port authorities, as well as civil engineering consultants and contractors involved in planning and designing dredging, maritime infrastructure and fluvial projects.

Book Synopsis The Philosophy of Umberto Eco by : Sara G. Beardsworth
Download or read book The Philosophy of Umberto Eco written by Sara G. Beardsworth and published by Open Court Publishing. This book was released on 2017-05-09 with total page 758 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Philosophy of Umberto Eco stands out in the Library of Living Philosophers series as the volume on the most interdisciplinary scholar hitherto and probably the most widely translated. The Italian philosopher’s name and works are well known in the humanities, both his philosophical and literary works being translated into fifteen or more languages. Eco is a founder of modern semiotics and widely known for his work in the philosophy of language and aesthetics. He is also a leading figure in the emergence of postmodern literature, and is associated with cultural and mass communication studies. His writings cover topics such as advertising, television, and children’s literature as well as philosophical questions bearing on truth, reality, cognition, language, and literature. The critical essays in this volume cover the full range of this output. This book has wide appeal not only because of its interdisciplinary nature but also because of Eco’s famous “high and low” approach, which is deeply scholarly in conception and very accessible in outcome. The short essay “Why Philosophy?” included in the volume is exemplary in this regard: it will appeal to scholars for its wit and to high school students for its intelligibility.
