Book excerpt: DEUX NOUVEAUX DETECTEURS OPTIQUES ONT ETE REALISE ET QUI ONT POUR ORIGINALITE, PAR RAPPORT AUX DETECTEURS USUELS, DE DONNER UNE MESURE DE LA COULEUR SANS RECOURS A DES JEUX DE FILTRES OPTIQUES. LE PREMIER DETECTEUR EST FORME PAR UNE DOUBLE JONCTION ENTERRE (BDJ). CONTRAIREMENT A LA PHOTODIODE, LA OU LA SORTIE DONNE LIEU A UN SEUL PHOTOCOURANT, LA STRUCTURE A DOUBLE JONCTION ENTERREE PERMET D'AVOIR DEUX COURANTS MESURABLES : I 1 ET I 2. L'AVANTAGE DE LA STRUCTURE BDJ RESIDE DANS LA REPARTITION SPECTRALE DES DEUX PHOTOCOURANTS. LE COURANT I 1 A UN MAXIMUM DANS LE BLEU, TANDIS QUE I 2 TIENS SON MAXIMUM DANS LE ROUGE. EN APPELONS R LE RAPPORT I 2/I 1, ON ETABLIT QU'IL EST UNE FONCTION STRICTEMENT CROISSANTE AVEC LA LONGUEUR D'ONDE. DE PLUS, LE RAPPORT R PERMET D'ELIMINER LE FACTEUR FLUX, CE QUI LE REND INSENSIBLE A LA FLUCTUATION DE LA PUISSANCE LUMINEUSE. CETTE PROPRIETE A ETE MISE EN EVIDENCE DANS DES APPLICATIONS TEL QUE LA SPECTROPHOTOMETRIE ET MESURE DU PH. LE SECOND DETECTEUR EST UNE TRIPLE JONCTION ENTERRE (BTJ). CETTE STRUCTURE EST CONSTITUEE D'UNE TRIPLE JONCTION PN ENTERREE. LE PROCEDE DE FABRICATION EST REALISE PAR LA TECHNOLOGIE BICMOS. CETTE STRUCTURE A PERMIT L'EXTRACTION DE TROIS COURANTS MESURABLES : I 1 (MAXIMUM DANS LE BLEU), I 2 (MAXIMUM DANS LE VERT) ET I 3 (MAXIMUM DANS LE ROUGE). CE DISPOSITIF PERMET LA DETECTION DE TROIS COMPOSANTE SPECTRALE QUI DETERMINE LA COULEUR DE LA LUMIERE OU D'UN OBJET. AINSI L'UTILISATION DE FILTRE OPTIQUE DEPOSE SUR LE DETECTEUR N'EST PLUS NECESSAIRE POUR DETERMINER LA COULEUR COMME C'EST LE CAS POUR LES DISPOSITIFS CCD. DANS LE DOMAINE DE L'IMAGERIE, L'UTILISATION DE STRUCTURES BTJ PERMET DE DIMINUER LE COUT DE FABRICATION ET D'ACCROITRE LA SENSIBILITE.

This book was released on 1999 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: LE DEVELOPPEMENT RECENT DES CAPTEURS OPTIQUES INTEGRES EN TECHNOLOGIE CMOS A PERMIS DE FAIRE PROGRESSER CONSIDERABLEMENT LA REALISATION DE MICRO-SYSTEMES POUR L'IMAGERIE ELECTRONIQUE ET L'INSTRUMENTATION. CEPENDANT, LA STRUCTURE DE BASE UTILISEE POUR LA DETECTION DE LA COULEUR EST RESTEE CONVENTIONNELLE. AINSI, UN CAPTEUR CMOS OU A CCD UTILISE GENERALEMENT UN JEU DE TROIS FILTRES OPTIQUES ROUGE, VERT ET BLEU (R, V, B) DEPOSES SUR LES SURFACES RESPECTIVES DE TROIS PHOTO-DETECTEURS, POUR AVOIR UNE INFORMATION SUR LA COULEUR D'UN PIXEL DE L'IMAGE. CECI A POUR CONSEQUENCE D'AUGMENTER LA SURFACE ET LE PRIX DU SYSTEME DE DETECTION. AFIN DE POUVOIR DEVELOPPER DES SYSTEMES DE MESURE DE COULEUR PERFORMANTS, DE TAILLE REDUITE ET DE FAIBLE COUT, NOUS NOUS SOMMES PROPOSES DE DEVELOPPER DE NOUVELLES STRUCTURES POUR LA DETECTION DE LA COULEUR. NOUS AVONS DONC UTILISE LA PROPRIETE DE FILTRAGE OPTIQUE QUE PRESENTE UNE JONCTION ENTERREE POUR REALISER DEUX DETECTEURS DE COULEUR. LE PREMIER DETECTEUR, CONSTITUE DE DEUX JONCTIONS ENTERREES, A ETE REALISE DANS UNE TECHNOLOGIE CMOS. IL PERMET DE DETERMINER LA PUISSANCE LUMINEUSE ET LA LONGUEUR D'ONDE D'UNE LUMIERE MONOCHROMATIQUE. LE DEUXIEME DETECTEUR, CONSTITUE PAR UN EMPILEMENT DE TROIS JONCTIONS ENTERREES REALISE DANS UNE TECHNOLOGIE BICMOS, PERMET DE DETERMINER LES TROIS COMPOSANTES R, V, B DE LA COULEUR. NOUS NOUS SOMMES ENSUITE INTERROGES SUR LA QUALITE COLORIMETRIQUE DU DETECTEUR A TROIS JONCTIONS ENTERREES. NOUS AVONS DONC DEVELOPPES LA CARACTERISATION COLORIMETRIQUE QUI DEFINIT LA RELATION ENTRE L'ESPACE COLORIMETRIQUE DU DETECTEUR ET CELUI DE L'OBSERVATEUR STANDARD DE LA CIE (COMITE INTERNATIONALE DE L'ECLAIRAGE). AVEC UNE REGRESSION LINEAIRE PAR LE CRITERE DES MOINDRES CARRES, NOUS AVONS PU MINIMISER LES DIFFERENCES DE COULEUR ENTRE LES SPECIFICATIONS DU DETECTEUR ET CELLES DE L'OBSERVATEUR STANDARD CIE 1931. NOUS AVONS ENSUITE PROPOSE DES STRUCTURES DE PIXELS ACTIFS AFIN DE DEVELOPPER DES CAPTEURS INTEGRES UTILISANT NOS DETECTEURS DE COULEUR. NOUS AVONS UTILISE CES STRUCTURES POUR DEVELOPPER UNE BARRETTE DE 64 PIXELS A DEUX JONCTIONS ENTERREES. LES RESULTATS DE TEST ONT MONTRE UNE LARGE DYNAMIQUE EN TERME DE DETECTION DE L'INTENSITE LUMINEUSE ET UNE FAIBLE DISPARITE ENTRE LES REPONSES DES PIXELS.

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.

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.

Book excerpt: NEW YORK TIMES BESTSELLER • “A fascinating look at how consumers perceive logos, ads, commercials, brands, and products.”—Time How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? In Buyology, Martin Lindstrom presents the astonishing findings from his groundbreaking three-year, seven-million-dollar neuromarketing study—a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what captures our interest—and drives us to buy. Among the questions he explores: • Does sex actually sell? • Does subliminal advertising still surround us? • Can “cool” brands trigger our mating instincts? • Can our other senses—smell, touch, and sound—be aroused when we see a product? Buyology is a fascinating and shocking journey into the mind of today's consumer that will captivate anyone who's been seduced—or turned off—by marketers' relentless attempts to win our loyalty, our money, and our minds.

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.
