In this book, two kinds of analysis based on acoustic emission recorded during mechanical tests are investigated. In the first, individual, analysis, acoustic signature of each damage mechanism is characterized. So with a clustering method, AE signals that have similar shapes or similar features can be group together into a cluster. Afterwards, each cluster can be linked with a main damage. The second analysis is based on a global AE analysis, on the investigation of liberated energy, with a view to identify a critical point. So beyond this characteristic point, the criticality can be modeled with a power-law in order to evaluate time to failure.
Elasticity is absolutely necessary for living a normal life. This fact is cruelly revealed when respiratory, cardiac, digestive, sensory, motor, reproductive or aesthetic problems appear following the inexorable decline of our elastic capital. The protection and maintenance of this capital is one of life’s priorities since this declination begins at the age of twenty and accelerates in times of crises and pandemics. However, there are no therapies yet designed to remedy it. The first part of the book explains the consequences surrounding a lack of elasticity in the skin, the most visible decline, and then other defects in elasticity throughout our bodies, exploring places rarely mentioned. The second part describes the research fighting against elasticity anomalies and examines useful behaviors to protect our elastic capital (e.g. our diets and physical and cognitive activities). This last point is at the heart of current social debates on nutritional, behavioral, environmental and even ethical levels.
Against this current trend of low growth and high uncertainty, business directors must work with their shareholders to set strategic objectives and define business models. The great number of possible strategies makes this type of management very complex, and the actual deployment of strategic choices is often limited by a lack of overall coherence within the organization. This problem calls for an appropriate and renewed response. In strategic management today, a closer, permanent dialogue is needed between operational and financial performance. Based on a supply chain approach, the Value Added Supply Chain (VASC) model focuses on driving operational performance, but aims to achieve a greater and more dynamic integration between these two dimensions of the company's value creation.
Describes the interplay between the probabilistic structure (independence) and a variety of tools ranging from functional inequalities to transportation arguments to information theory. Applications to the study of empirical processes, random projections, random matrix theory, and threshold phenomena are also presented.
Originally published in France in 2012, Pascal Mégeau's definitive biography of legendary film director Jean Renoir is a landmark work-the winner of a Prix Goncourt, France's top literary achievement. Now available in the English language for the first time, Jean Renoir: A Biography, is the definitive study of one of the most fascinating and creative artistic figures of the twentieth century. The French filmmaker made more than forty films from the silent era to the late '60s and today he is revered by filmmakers and seen by many as one of the greatest of all time. Renoir made acclaimed movies in France, America, India, and Italy and became a writer during the last part of his life. An estimated 75 percent of the book details previously unknown information about the filmmaker, including Renoir's close affiliation with Communism in the '30s (when he was the Party's official director) and his work with the fascist regimes during World War II; his previously uncredited Hollywood film, The Amazing Mrs. Holiday; and new information on the making of his most famous films. Drawing from unpublished or little known sources, this biography is a completely fresh approach to the maker of Grand Illusion and The Rules of the Game, redefining the very function of the movie director and simultaneously recounting the history of a century.
Comment penser la puissance africaine et les enjeux de la transition hgmonique globale au 21e sicle ? Telle est la question thmatique centrale de cet ouvrage qui se veut un cahier de recherche doctrinale en polmologie et en irnologie endognes, dans un contexte o la mondialisation des enjeux scuritaires signifie pour lAfrique, un reclassement gostratgique du continent o le maintien de la paix et la rsolution des conflits sont devenus un terrain daffirmation de puissance. Analytique et oprationnelle, cette publication est le fruit de nombreuses expriences de terrain, de missions denseignements, de travaux ditoriaux, de publications scientifiques et de confrences internationales.
Concentration inequalities have been recognized as fundamental tools in several domains such as geometry of Banach spaces or random combinatorics. They also turn to be essential tools to develop a non asymptotic theory in statistics. This volume provides an overview of a non asymptotic theory for model selection. It also discusses some selected applications to variable selection, change points detection and statistical learning.
Do you believe in the persistence of the human soul? Convinced that we live through multiple iterations of life on Earth before finally achieving enlightenment and moving to the next plane of being? Interested in learning more about the early Western response to the Buddhist and Hindu doctrines of reincarnation? If so, be sure to put this tract from French theosophy and theology expert Theodore Pascal on your must-read list.
Emotions are as old as humankind. But what do we know about them and what importance do we assign to them? Emotional Lexicons is the first cultural history of terms of emotion found in German, French, and English language encyclopaedias since the late seventeenth century. Insofar as these reference works formulated normative concepts, they documented shifts in the way the educated middle classes were taught to conceptualise emotion by a literary medium targeted specifically to them. As well as providing a record of changing language use (and the surrounding debates), many encyclopaedia articles went further than simply providing basic knowledge; they also presented a moral vision to their readers and guidelines for behaviour. Implicitly or explicitly, they participated in fundamental discussions on human nature: Are emotions in the mind or in the body? Can we "read" another person's feelings in their face? Do animals have feelings? Are men less emotional than women? Are there differences between the emotions of children and adults? Can emotions be "civilised"? Can they make us sick? Do groups feel together? Do our emotions connect us with others or create distance? The answers to these questions are historically contingent, showing that emotional knowledge was and still is closely linked to the social, cultural, and political structures of modern societies. Emotional Lexicons analyses European discourses in science, as well as in broader society, about affects, passions, sentiments, and emotions. It does not presume to refine our understanding of what emotions actually are, but rather to present the spectrum of knowledge about emotion embodied in concepts whose meanings shift through time, in order to enrich our own concept of emotion and to lend nuances to the interdisciplinary conversation about them.
