LES RESEAUX A TRES HAUT DEBIT (SUPERIEUR A 100 MBITS/S) DEMANDENT TOUJOURS DES ATTENTIONS PARTICULIERES TANT EN ETUDE QU'EN ARCHITECTURE. CETTE THESE CONTIENT L'ARCHITECTURE EN COUCHES OSI D'UN RESEAU A TRES HAUT DEBIT. AINSI, LE RESEAU ESCALIBUR QUI EST UN RESEAU D'ENTREPRISE DE DEUXIEME GENERATION EST MINUTIEUSEMENT ETUDIE. SELON LES TERMES DE LA NORME ISO, LE COMMUNICATEUR ESCALIBUR, PARTIE PRINCIPALE DU RESEAU, DOIT REALISER LE NIVEAU PHYSIQUE ET UNE PARTIE DU NIVEAU LIAISON. L'AUGMENTATION DE LA VITESSE DE TRANSMISSION ET LES PROBLEMES QUI Y SONT LIES, AINSI QUE LES METHODES CONCERNANT CETTE AUGMENTATION SONT ETUDIES. POUR REALISER CES OBJECTIFS, PREMIEREMENT, IL FAUT OPTIMISER LES PARAMETRES DU RESEAU (M, TAUX DE BIT ET N, NOMBRE DE FILS), CE QUI EST FAIT PAR COMPARAISON DES DIVERS SUPPORTS DE TRANSMISSION, ET DEUXIEMEMENT DEFINIR LE DEBIT LIMITE DU COMMUNICATEUR, CE QUI EST FAIT PAR COMPARAISON DES DIVERSES TECHNOLOGIES DES CIRCUITS INTEGRES LOGIQUES QUI ABOUTIT AU CHOIX DE LA TECHNOLOGIE ECL, LA TECHNOLOGIE CONVENABLE AU TAUX DE BIT ELEVES. LE SUPPORT DE TRANSMISSION IDEAL POUR CE RESEAU EST LA FIBRE OPTIQUE DONC L'ETUDE DU SYSTEME OPTIQUE ET LA PROPORTION DES COMPOSANTS OPTIQUES (LA DIODE LASER, LA DIODE AVALANCHE, ETC.) SERONT LES DERNIERES ETAPES DE CETTE ETUDE

South Asia Rural Development Series. India's economic policies are aimed at increasing economic growth, improving market efficiency and competitiveness, and integrating the Indian economy with global markets. Much of the population and industrial growth is expected to occur in urban centers. Consequently, the demands on the Urban Water Supply and Sanitation sector (UWSS), will be great. Urban Water Supply and Sanitation states the UWSS sector needs urgent attention both to meet these new demands and to ensure that all city-dwellers have access to basic services at reasonable costs. This book outlines the way forward which includes a discussion on institutional reform and financial reform as well an action plan.

Book Description
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.

Book Description
Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Book Description
The evolution of broadband access networks toward bimodal fiber-wireless (FiWi) access networks, described in this book, may be viewed as the endgame of broadband access. After discussing the economic impact of broadband access and current worldwide deployment statistics, all the major legacy wireline and wireless broadband access technologies are reviewed. State-of-the-art GPON and EPON fiber access networks are described, including their migration to next-generation systems such as OCDMA and OFDMA PONs. The latest developments of wireless access networks are covered, including VHT WLAN, Gigabit WiMAX, LTE and WMN. The advantages of FiWi access networks are demonstrated by applying powerful network coding, heterogeneous optical and wireless protection, hierarchical frame aggregation, hybrid routing and QoS continuity techniques across the optical-wireless interface. The book is an essential reference for anyone working on optical fiber access networks, wireless access networks or converged FiWi systems.

Book Description
Higher Education Leadership and Management have become increasingly important throughout the years due to the complexities that have to be addressed by universities worldwide. This can be seen not only in professionalisation in fields such as faculty management or in areas of quality assurance and internationalisation, but also in the need for exchange and training in academic leadership, such as that of deans or study deans, or of university leadership in general. The Dialogue on Innovative Higher Education Strategies (DIES) is addressing this need in emerging countries by building platforms of exchange and offering training courses. Not only is the programme supporting capacity building of human resources, but it is also specifically focusing on inducing change within the universities, such as introducing new instruments or tools in the area of quality assurance and internationalisation, and addressing specific challenges or setting up new structures in the form of projects in the frame of the training. The ‘National Multiplication Trainings’ Programme under DIES is further addressing the sustainability and multiplication of the DIES Programme, that is, alumni are enabled to implement capacity building in higher education leadership and management in their national context. The articles within this volume of the “Potsdamer Beiträge zur Hochschulforschung” (Potsdam Contributions to Higher Education Research) analyse and share the experiences of such training programmes held in Colombia, Democratic Republic of Congo, Guinea, Malaysia, Kenya, and Uganda. They all revolve around the best ways to address the needs and challenges in higher education leadership and management, and in building capacities in these areas.
