Book Description
Dans le cadre de ce sujet de thèse, on s'intéresse à la surveillance des systèmes hybrides à forte dynamique événementielle. L'objectif est de détecter les défauts permanents et intermittents qui causent l'accélération et le ralentissement des tâches des systèmes. C'est dans ce contexte que se situent les principales contributions suivantes des travaux consignés dans la présente thèse : - Le développement d'une méthode de surveillance des processus basée sur les automates hybrides linéaires (AHL). Cette méthode consiste en premier lieu à l'établissement du modèle AHL du système dynamique en tenant compte des contraintes physiques et dynamiques de celui-ci. - La réalisation d'une analyse d'atteignabilité qui consiste à définir toutes les trajectoires pouvant amener le système à son objectif tout en respectant le cahier des charges qui lui est imposé. L'extension de l'approche en utilisant les automates hybrides rectangulaires. Cette sous-classe d'automates nous a permis de modéliser des systèmes plus complexes donc une modélisation hybride riche et a permis également une analyse formelle. Cette partie a été ponctuée par l'implémentation du système de surveillance qui consiste à déterminer les équations caractérisant chaque sommet de l'automate qui modélise le système.

Book Description
The first book in inference for stochastic processes from a statistical, rather than a probabilistic, perspective. It provides a systematic exposition of theoretical results from over ten years of mathematical literature and presents, for the first time in book form, many new techniques and approaches.

Book Description
This book summarizes current knowledge regarding the theory of estimation for semiparametric models with missing data, in an organized and comprehensive manner. It starts with the study of semiparametric methods when there are no missing data. The description of the theory of estimation for semiparametric models is both rigorous and intuitive, relying on geometric ideas to reinforce the intuition and understanding of the theory. These methods are then applied to problems with missing, censored, and coarsened data with the goal of deriving estimators that are as robust and efficient as possible.

Book Description
Creativity has become a central concept in trying to understand the contemporary economy. It is a universally accepted strategic asset and a key issue in developing economic policy. But at the same time, this lauding of the creative economy raises many questions. What can creativity really do for us? What challenges does it pose for the management and organization of companies? And, in an age when everyone tries to be creative, what does the concept even mean? This book deals with these issues, and is an engagement with the manifold ways in which creativity emerges as energy and functions as an organizing principle in modern organizations. The book presents a wide variety of approaches to understanding one of the most critical and exciting issues in modern management, with sections dedicated to the organization of innovation and creativity, leadership and management in creative endeavors, as well as creativity and organization change.

Book Description
Bernard Walsh, agnostic theologian, has a professional interest in heaven. But when he travels to Hawaii with his reluctant father Jack, to visit Jack's dying, estranged sister it feels more like purgatory than paradise. Surrounded by quarrelling honeymooners, a freeloading anthropologist and assorted tourists in search of their own personal paradise, and with his father whisked off to hospital after an unfortunate accident, Bernard is beginning to regret ever coming to Haiwaii. Until, that is, he stumbles on something he had given up hope of finding: the astonishing possibility of love.

Book Description
Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book Description
This text on the interdisciplinary field of synergetics will be of interest to students and scientists in physics, chemistry, mathematics, biology, electrical, civil and mechanical engineering, and other fields. It continues the outline of basic con cepts and methods presented in my book Synergetics. An Introduction, which has by now appeared in English, Russian, J apanese, Chinese, and German. I have written the present book in such a way that most of it can be read in dependently of my previous book, though occasionally some knowledge of that book might be useful. But why do these books address such a wide audience? Why are instabilities such a common feature, and what do devices and self-organizing systems have in common? Self-organizing systems acquire their structures or functions without specific interference from outside. The differentiation of cells in biology, and the process of evolution are both examples of self-organization. Devices such as the electronic oscillators used in radio transmitters, on the other hand, are man made. But we often forget that in many cases devices function by means of pro cesses which are also based on self-organization. In an electronic oscillator the motion of electrons becomes coherent without any coherent driving force from the outside; the device is constructed in such a way as to permit specific collective motions of the electrons. Quite evidently the dividing line between self-organiz ing systems and man-made devices is not at all rigid.

Book Description
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.
