Book excerpt: CETTE ETUDE A POUR OBJET D'ETUDIER LES ERREURS RESIDUELLES DANS UNE DIFFUSION NUMERIQUE PAR SATELLITE DE PROGRAMMES DE TELEVISION. ELLE CONCERNE LA MODELISATION, LES STRATEGIES DE MASQUAGE ET L'INFLUENCE SUR LA QUALITE SUBJECTIVE DES IMAGES ET DU SON DE CES ERREURS. NOUS AVONS D'ABORD ETUDIE ET SIMULE UN SYSTEME COMPLET DE TRANSMISSION SIMPLIFIE DE BOUT EN BOUT AFIN DE MODELISER LES ERREURS RESIDUELLES. PUIS NOUS AVONS CALCULE ET IMPLANTE CES MODELES PRATIQUES DANS UN GENERATEUR D'INJECTION D'ERREURS LOGICIEL SIMULANT LA DIFFUSION. NOUS NOUS SOMMES ENSUITE INTERESSE AUX STRATEGIES DE MASQUAGE QUE NOUS AVONS IMPLANTE DANS UN DECODEUR VIDEO. LA PREMIERE SOLUTION EST UTILISEE PAR LES CONSTRUCTEURS DE CODEURS MPEG-2: ELLE UTILISE UN LIEN ENTRE LA COUCHE SYSTEME ET LE DECODEUR. EN CAS D'ERREUR, ELLE AVERTIT LE DECODEUR DE SAUTER LE PAQUET DE TRANSPORT ERRONE ET DE SE RESYNCHRONISER SUR UN CODE DE DEBUT. DANS UNE DEUXIEME SOLUTION PLUS ORIGINALE, LE DECODEUR ANALYSE LE TRAIN BINAIRE QUEL QUE SOIT SON ETAT ET UTILISE DES TESTS INTERNES POUR DETECTER LES ERREURS ET SE RESYNCHRONISER. NOUS AVONS ENSUITE MIS EN PLACE UNE SALLE DE TESTS SUBJECTIFS. NOUS AVONS ETUDIE LES DIFFERENTS PROTOCOLES DE TEST NORMALISES ET CHOISI LA METHODE A DOUBLE STIMULUS A ECHELLE A CINQ NOTES DE QUALITE. NOUS AVONS EFFECTUE DE NOMBREUX TESTS AFIN D'ESTIMER LA PRECISION DES RESULTATS OBTENUS. NOUS AVONS FINALEMENT TESTE LES DEUX DECODEURS VIDEO AINSI QU'UN DECODEUR AUDIO MPEG COUCHE II. NOUS AVONS AINSI PU DETERMINER LE SEUIL DE PERCEPTION AUX ERREURS ET LA LIMITE DE FONCTIONNEMENT DU DECODEUR COMPLET

Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive view of the most recent major international research in the field of tolerancing, and is an excellent resource for anyone interested in Computer Aided Tolerating. It is organized into 4 parts. Part 1 focuses on the more general problems of tolerance analysis and synthesis, for tolerancing in mechanical design and manufacturing processes. Part 2 specifically highlights the simulation of assembly with defects, and the influence of tolerances on the quality of the assembly. Part 3 deals with measurement aspects, and quality control throughout the life cycle. Different measurement technologies and methods for estimating uncertainty are considered. In Part 4, different aspects of tolerancing and their interactions are explored, from the definition of functional requirement to measurement processes in a PLM approach.

Available in PDF, EPUB and Kindle. Book excerpt: We live in turbulent times with continents and nations facing ever-heightening risks such as natural disasters, intense and protracted conflicts, terrorism, corporate crises, cyber threats to infrastructures and mega-events. We are witnessing the rise of mega-crises and a new class of adversity with many unknowns. The prospect of mega-crises presents professionals and students in the field of crisis management with four major tasks. First, they should engage in “deep thinking” about the causes of the increasing occurrence of mega-crises. Second, they should identify and work through the dominant trends which complicate contemporary crisis management. Third, they should upgrade institutional crisis management capacity. Fourth, they should improve societal resilience since no institutional complex can mitigate or manage these mega-crisis on its own. This book is divided into four primary parts, each of which looks at one facet of mega-crises. Part I focuses on the concept of a mega-crisis and mega-crisis management; Part II examines crisis management of mega-natural disasters; Part III evaluates crisis management of man-made mega-crises; and Part IV identifies mega-threats and vulnerabilities. Additional major topics include Hurricane Katrina; Hurricane Gustav; the London Bombings; the Mumbai Terrorist Attacks of July 7, 2005; corporate meltdowns; the subprime crisis; the Olympic Games; electricity grids; global climate change; the Dutch Delta; risks to food security; and mega-crises and the Internet. This comprehensive text will provide practitioners and academics with the results of an across-the-board research effort in the prospects, nature, characteristics, and the effects of mega-crises.

This symposium was sponsored by the International Astronomical Union, the International Association of Geodesy, the International Union of Theoretical and Applied Mechanics and COSPAR (Committee on Space Research). The organizing committee was composed of Dr. KOVALEVSKY chair man, Dr. Yu. V. BATRAKOV representing IAU, Dr. A. H. COOK for lAG, Dr. D. KING-HELE for COSPAR, Prof. M. Roy for IUTAM and Dr. ROSENBERG. I wish to take advantage of the opportunity to thank, on behalf of all the participants, the organizing committee members, Prof. BUCHAR, Dr. RAJSK:I and Dr. SEHNAL, for the kindness and efficiency of their welcome. The interpreters who translated with virtuosity during the whole symposium also deserve our gratitude. I am grateful also for the care and skill with which Springer-Verlag has printed this volume.
