Book excerpt: LA REDUCTION DE L'EMISSION PARASITE EST DEVENUE UNE CONTRAINTE MAJEURE DANS LA CONCEPTION DES CIRCUITS INTEGRES. PORTANT INITIALEMENT SUR LES EQUIPEMENTS ELECTRONIQUES, LA CONTRAINTE DE COMPATIBILITE ELECTROMAGNETIQUE S'EST REPERCUTEE SUR LE COMPOSANT LUI MEME, DU FAIT DE L'EVOLUTION TECHNOLOGIQUE ET DE L'AVENEMENT DES SYSTEMES SUR PUCE. LES CIRCUITS INTEGRES DOIVENT DE CE FAIT ETRE SELECTIONNES, AINSI QUE LEURS COMPOSANTS ENVIRONNANTS, DE MANIERE A RESPECTER LES CONTRAINTES CEM DE L'EQUIPEMENT. CEPENDANT, LE COMPORTEMENT CEM DU COMPOSANT FAIT ENCORE RAREMENT PARTIE DE LA SPECIFICATION INITIALE DE CONCEPTION. DE PLUS, NI METHODOLOGIE, NI OUTILS DE SIMULATION PERFORMANTS NE SONT DISPONIBLE. NOTRE TRAVAIL DE THESE CONSISTE, D'UNE PART, A METTRE EN UVRE DES METHODES DE MESURES FIABLES POUR CARACTERISER L'EMISSION PARASITE DU COMPOSANT. CES METHODES S'APPLIQUENT AU MODE CONDUIT ET RAYONNE, SONT REPRODUCTIVES AFIN DE PERMETTRE DE COMPARER ET EVALUER DIFFERENTS PRODUITS. D'AUTRE PART, NOTRE EFFORT A PORTE SUR LA CONSTRUCTION D'UN MODELE GENERAL DU COMPOSANT AFIN DE PREDIRE L'EMISSION PARASITE DE MANIERE SIMPLE ET PRECISE DE 1 A 1000 MHZ. CETTE APPROCHE PERMET D'ANALYSER L'IMPACT DE TECHNIQUES DE REDUCTION D'EMISSION AVANT LA FABRICATION DU COMPOSANT. NOUS AVONS DECRIT DIFFERENTES TECHNIQUES DE REDUCTION DE L'EMISSION PARASITE AU NIVEAU CIRCUIT INTEGRE ET BOITIER. LE MODELE CEM PROPOSE RESPECTE LA CONFIDENTIALITE DE LA STRUCTURE ET DE LA TECHNOLOGIE, TOUT EN ETANT COMPATIBLE AVEC LES OUTILS DE SIMULATION. LE MODELE EST GENERIQUE, PERMETTANT DE S'ADAPTER A TOUS TYPES DE COMPOSANTS, DES ASIC AUX MICROPROCESSEURS, A DES FINS DE NORMALISATION DE LA DESCRIPTION CEM DES COMPOSANTS. LE TRAVAIL A ETE CONDUIT EN COOPERATION AVEC ST MICROELECTRONICS

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.
