This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette these se situe dans le domaine de la microelectronique en haute temperature. Actuellement les technologies de circuits integres plus poussees, en termes de densite d'integration, cout, et fiabilite, utilisent encore le silicium comme materiau de base. Ces technologies sont concues pour permettre une large duree de vie, dans une plage de temperature donnee, typiquement de 0 a 100 c. D'autres technologies se developpent aussi, notamment le sic (de plus large bande interdite) et le soi couche mince (ou la surface des jonctions parasites son fortement reduites), pour satisfaire les besoins des applications a des tres hautes temperatures. Ayant actuellement des performances inferieures, en termes de cout et de densite d'integration, elles restent beaucoup moins competitives que les technologies standards sur substrat de silicium. De plus, il est prevu que, dans les prochains dix ans, plus de 70% des applications en haute temperature correspondront encore a des applications automobiles et petrolieres ayant des temperatures d'operation intermediaires, inferieures a 200 c. A partir de l'etude de la physique des composants semiconducteurs et des materiaux pour la microelectronique, cette these elargit jusqu'a environ 250 c la plage de temperature d'utilisation des technologies cmos et bicmos standards, sur substrat de silicium, a travers des techniques de conception de circuits integres, sans toutefois modifier les procedes de fabrication. Les etudes et les tests ont ete experimentes sur une technologie cmos et une technologie bicmos commerciales. Ces conclusions sont transferables a toute technologie semblable actuelle. De plus, les performances en temperature semblent ameliorer dans le futur, du fait que l'augmentation de la densite d'integration entraine une augmentation des concentrations des dopants et une reduction de la surface des jonctions d'isolation. Deux applications industrielles, representatives du marche potentiel des applications des circuits integres en haute temperature, ont permis de verifier dans la pratique les resultats theoriques obtenus.

Book excerpt: CETTE THESE SE SITUE DANS LE DOMAINE DE LA MICROELECTRONIQUE EN HAUTE TEMPERATURE. ACTUELLEMENT LES TECHNOLOGIES DE CIRCUITS INTEGRES PLUS POUSSEES, EN TERMES DE DENSITE D'INTEGRATION, COUT, ET FIABILITE, UTILISENT ENCORE LE SILICIUM COMME MATERIAU DE BASE. CES TECHNOLOGIES SONT CONCUES POUR PERMETTRE UNE LARGE DUREE DE VIE, DANS UNE PLAGE DE TEMPERATURE DONNEE, TYPIQUEMENT DE 0 A 100\C. D'AUTRES TECHNOLOGIES SE DEVELOPPENT AUSSI, NOTAMMENT LE SIC (DE PLUS LARGE BANDE INTERDITE) ET LE SOI COUCHE MINCE (OU LA SURFACE DES JONCTIONS PARASITES SON FORTEMENT REDUITES), POUR SATISFAIRE LES BESOINS DES APPLICATIONS A DES TRES HAUTES TEMPERATURES. AYANT ACTUELLEMENT DES PERFORMANCES INFERIEURES, EN TERMES DE COUT ET DE DENSITE D'INTEGRATION, ELLES RESTENT BEAUCOUP MOINS COMPETITIVES QUE LES TECHNOLOGIES STANDARDS SUR SUBSTRAT DE SILICIUM. DE PLUS, IL EST PREVU QUE, DANS LES PROCHAINS DIX ANS, PLUS DE 70% DES APPLICATIONS EN HAUTE TEMPERATURE CORRESPONDRONT ENCORE A DES APPLICATIONS AUTOMOBILES ET PETROLIERES AYANT DES TEMPERATURES D'OPERATION INTERMEDIAIRES, INFERIEURES A 200\C. A PARTIR DE L'ETUDE DE LA PHYSIQUE DES COMPOSANTS SEMICONDUCTEURS ET DES MATERIAUX POUR LA MICROELECTRONIQUE, CETTE THESE ELARGIT JUSQU'A ENVIRON 250\C LA PLAGE DE TEMPERATURE D'UTILISATION DES TECHNOLOGIES CMOS ET BICMOS STANDARDS, SUR SUBSTRAT DE SILICIUM, A TRAVERS DES TECHNIQUES DE CONCEPTION DE CIRCUITS INTEGRES, SANS TOUTEFOIS MODIFIER LES PROCEDES DE FABRICATION. LES ETUDES ET LES TESTS ONT ETE EXPERIMENTES SUR UNE TECHNOLOGIE CMOS ET UNE TECHNOLOGIE BICMOS COMMERCIALES. CES CONCLUSIONS SONT TRANSFERABLES A TOUTE TECHNOLOGIE SEMBLABLE ACTUELLE. DE PLUS, LES PERFORMANCES EN TEMPERATURE SEMBLENT AMELIORER DANS LE FUTUR, DU FAIT QUE L'AUGMENTATION DE LA DENSITE D'INTEGRATION ENTRAINE UNE AUGMENTATION DES CONCENTRATIONS DES DOPANTS ET UNE REDUCTION DE LA SURFACE DES JONCTIONS D'ISOLATION. DEUX APPLICATIONS INDUSTRIELLES, REPRESENTATIVES DU MARCHE POTENTIEL DES APPLICATIONS DES CIRCUITS INTEGRES EN HAUTE TEMPERATURE, ONT PERMIS DE VERIFIER DANS LA PRATIQUE LES RESULTATS THEORIQUES OBTENUS.

Available in PDF, EPUB and Kindle. Book excerpt: Out-of-print for years, this highly sought-after volume, remains the most popular reference on inertial navigation systems analysis. Finally, this classic book is back in print and readily available only from Artech House. Authored by a pioneer in the field, this authoritative resource focuses on terrestrial navigation, but is also useful for air and sea applications. Packed with valuable, time-saving equations and models, the book helps engineers design optimal navigation systems by comparing the performance of the various types of system mechanizations. Although applications and technology have changed over the years, this book remains the best source for fundamental inertial navigation system knowledge, from notational conventions, reference frames, and geometry of the earth, to unified error analysis, self-alignment techniques, and the development of a system error model. This well-illustrated, timeless reference belongs on the shelf of every practicing engineer working in this area.

Download or read book Fundamentals of Human Computer Interaction written by Andrew F. Monk and published by Academic Press. This book was released on 2014-06-28 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Human-Computer Interaction aims to sensitize the systems designer to the problems faced by the user of an interactive system. The book grew out of a course entitled ""The User Interface: Human Factors for Computer-based Systems"" which has been run annually at the University of York since 1981. This course has been attended primarily by systems managers from the computer industry. The book is organized into three parts. Part One focuses on the user as processor of information with studies on visual perception; extracting information from printed and electronically presented text; and human memory. Part Two on the use of behavioral data includes studies on how and when to collect behavioral data; and statistical evaluation of behavioral data. Part Three deals with user interfaces. The chapters in this section cover topics such as work station design, user interface design, and speech communication. It is hoped that this book will be read by systems engineers and managers concerned with the design of interactive systems as well as graduate and undergraduate computer science students. The book is also suitable as a tutorial text for certain courses for students of Psychology and Ergonomics.
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1976 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

Download or read book Nonhuman DNA Typing written by Heather Miller Coyle and published by CRC Press. This book was released on 2007-08-29 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The association of a suspect with the victim or crime scene through DNA evidence is one of the most powerful statements of complicity in a crime imaginable. No category of evidence has ever had the complete capacity to convict or exonerate an accused so absolutely in the eyes of the public. With the discriminatory powers of DNA and the variety of DNA markers now in regular use, the one thing keeping a third of all cases unsolved is the lack of human DNA evidence. However, the identification of polymorphic genetic loci in cats, dogs, plants, insects, bacteria, and viruses can provide the critical link between suspect and scene in the absence of human DNA. Non-Human DNA Typing: Theory and Casework Applications provides an introduction to the basic science underlying the emerging field of non-human DNA typing. It examines the use of non-human DNA evidence not just in homicide cases, but also in drug trafficking, poaching of endangered species, livestock fraud, and missing persons, as well as the identification of primary and secondary crime scenes. The book demonstrates the recognition, collection, and preservation of biological evidence at a crime scene, techniques of DNA fingerprinting, and DNA profiling. Using a wide variety of examples, applications, and case studies, the author describes the STR analysis of canine and feline samples, insects, and fungi, and their role as evidence in forensic science. Chapters consider the development of testing methods for animal evidence, soil DNA typing, and the use of DNA typing in wildlife investigations. A useful appendix includes an overview of the history of forensic serology and DNA. Combining science, case examples, legal decisions, and references, Non-Human DNA Typing: Theory and Casework Applications presents the forensic and legal applications of non-human DNA evidence for scientists, law enforcement, and attorneys.
