Book Description
L'objectif de cette thèse est d'apporter des contributions à une méthodologie intégrée pour l'identification et la commande des systèmes industriels. La première partie analyse les problématiques de la commande des systèmes industriels. On met l'accent sur la nécessité de disposer d'une méthode qui puisse conduire rapidement au calcul d'un régulateur robuste pour un large nombre d'applications réelles en suivant les trois étapes fondamentales : données Entrée/Sortie, identification du modèle, calcul du régulateur. Les limitations qui peuvent intervenir dans certaines applications à cause d'utilisations des techniques de commande des systèmes linéaires sont investiguées et le passage aux techniques de commande des systèmes non-linéaires est ainsi discuté. La deuxième partie est dédiée à l'étude des systèmes industriels linéaires monovariable. On présente une procédure basée sur l'interaction entre la commande et l'identification en boucle fermée : le calcul des régulateurs de complexité minimale est lié à l'utilisation de techniques d'identification en boucle fermée. Un cas d'étude réel (asservissement d'un système de portes d'accès d'un train) est utilisé pour décrire l'implémentation de la procédure. Une méthode pour l'ajustement des régulateurs PID destinés aux systèmes d'ordre élevé est aussi proposée. Les problèmes rencontrés dans la commande pour les moteurs Diesel turbochargé HDI nous ont amené à considérer le cas de la modélisation et identification d'une classe de modèle non-linéaires. Ceci constitue l'objet de la troisième partie de la thèse. Par analogie avec le cas linéaire, une méthode d'identification et une technique de commande des systèmes sont présentées

Book Description
Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects

Book Description
The problem that gives rise to this book is dissatisfaction with social science and social research as instruments of social problem solving. Policy makers and other practical problem solvers frequently voice disappointment with what they are offered. And many social scientists and social researchers think they should be more drawn upon, more useful, and more influential. Out of the discontent have come numerous diagnoses and prescriptions. This thoughtful contribution to the discussion provides an agenda of basic questions that should be asked and answered by those who are concerned about the impact of social science and research on real life problems. In general, Cohen and Lindblom believe that social scientists are crippled by a misunderstanding of their own trade, and they suggest that the tools of their trade be applied to the trade itself. Social scientists do not always fully appreciate that professional social inquiry is only one of several ways of solving a problem. They are also often engaged in a mistaken pursuit of authoritativeness, not recognizing that their contribution can never be more than a partial one. Cohen and Lindblom suggest that they reexamine their criteria for selecting subjects for research, study their tactics as compared to those of policy makers, and consider more carefully their role in relation to other routes to problem solving. To stimulate further inquiry into these fundamental issues, they also provide a comprehensive bibliography.

Book Description
Applying practical tools to the volatile process of negotiating Prognosticators apply Monte Carlo Analysis (MCA) to determine the likelihood and significance of a complete range of future outcomes; Real Options Analysis (ROA) can then be employed to develop pricing structures, or options, for such outcomes. Richard Razgaitis' Dealmaking shows readers how to apply these powerful valuation tools to a variety of business processes, such as pricing, negotiating, or living with a "deal," be it a technology license, and R&D partnership, or an outright sales agreement. Dealmaking distinguishes itself from other negotiating guides not only by treating negotiations as an increasingly common situation, but also by presenting a tool-based approach that creates flexible, practical valuation models. This forward-thinking guide includes a variety of checklists, case studies, and a CD-ROM with the appropriate software. Richard Razgaitis (Bloomsbury, NJ) is a Managing Director at InteCap, Inc. He has over twenty-five years of experience working with the development, commercialization, and strategic management of technology, seventeen of which have been spent in the commercialization of intellectual property.

Book Description
This publication presents the latest innovations and achievements of academic communities on Decision Support Systems (DSS). These advances include theory systems, computer-aided methods, algorithms, techniques and applications related to supporting decision making. The aim is to develop approaches for applying information systems technology to increase the effectiveness of decision making in situations where the computer system can support and enhance human judgements in the performance of tasks that have elements which cannot be specified in advance. Also it is intended to improve ways of synthesizing and applying relevant work from resource disciplines to practical implementation of systems that enhance decision support capability. The resource disciplines include: information technology, artificial intelligence, cognitive psychology, decision theory, organizational theory, operations research and modeling. Researchers come from the Operational Research area but also from Decision Theory, Multicriteria Decision Making methodologies, Fuzzy sets and modeling tools. Based on the introduction of Information and Communication Technologies in organizations, the decisional process is evolving from a mono actor to a multi actor situation in which cooperation is a way to make the decision.

Book Description
This groundbreaking new textbook offers extensive coverage of EU External Action studies, from its major concepts to the key theories in the field. Over the past decades, the European Union has progressively developed into a significant global actor in an increasing number of policy fields. This long-awaited volume looks into different ways of conceptualizing the EU as a global actor, the processes and impact of EU external action, explanations offered by IR and integration theories, the discursive, normative, practice and gender 'turns', and the 'decentring agenda' for EU external action. The book offers a reader-friendly guidance on these various ways in which to study the EU as a global actor: each chapter introduces one concept, approach or theory and illustrates its application by a case study of EU external action. In drawing the different perspectives together, the book underscores that 'EU External Action Studies' is becoming an academic speciality in its own right. Written by leading experts, the volume will make essential reading for students, scholars and practitioners of EU external action. EU External Action Studies nowadays attract attention from scholars and students in International Relations (IR), Foreign Policy Analysis and (interdisciplinary) EU Studies, as well as from practitioners.

Book Description
Collected Essays in Architectural Criticism is an indispensable anthology of writing by one of the most important voices in architectural theory of the last 50 years. Born in 1921, Colquhoun graduated from the Architectural Association in 1949. Currently Professor Emeritus of Architecture at Princeton University, he has taught at the AA, Cornell University and University College Dublin, among many other schools of architecture. He is the author of several books including the seminal Essays in Architectural Criticism, 1981, Modernity and the Classical Tradition, 1991, (both republished here in their entirety) and The Oxford History of Modern Architecture, 2002. This book includes essays from throughout Colquhoun's distinguished career. In his early writing Colquhoun subjects modern architecture to a far more thorough reading than was then customary. His meticulous evaluation of Modernism raised the standard of architectural historiography and has influenced new directions in theory and practice ever since. Collected Essays in Architectural Criticism encompasses the clarity of style and rigorous, erudite analysis that Colquhoun has brought to bear on a diverse range of subjects, including Le Corbusier, Robert Venturi and Denise Scott Brown, the Pompidou Centre, Postmodernism and the design of museums.
