This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ces dernières années, la quantité de données visuelles produites par divers types de capteurs est en augmentation permanente. L'interprétation et l'indexation automatique de telles données constituent des défis importants pour les domaines liés à la reconnaissance de formes et la vision par ordinateur. Dans ce contexte, la position relative des différents objets d'intérêt composant les images représente une information particulièrement importante pour interpréter leur contenu. Les relations spatiales sont en effet porteuses d'une sémantique riche, qui est fortement liée à la perception humaine. Les travaux de recherche présentés dans cette thèse proposent ainsi d'explorer différentes approches génériques de description de l'information spatiale, en vue de les intégrer dans des systèmes de reconnaissance et d'interprétation d'images de haut niveau. Tout d'abord, nous présentons une approche pour la description de configurations spatiales complexes, où les objets peuvent être imbriqués les uns dans les autres. Cette notion est formalisée par deux nouvelles relations spatiales, nommées enlacement et entrelacement. Nous proposons un modèle qui permet de décrire et de visualiser ces configurations avec une granularité directionnelle. Ce modèle est validé expérimentalement pour des applications en imagerie biomédicale, en télédétection et en analyse d'images de documents. Ensuite, nous présentons un cadre d'apprentissage de relations spatiales composites à partir d'ensembles d'images. Inspirée des approches par sacs de caractéristiques visuelles, cette stratégie permet de construire des vocabulaires de configurations spatiales apparaissant dans les images, à différentes échelles. Ces caractéristiques structurelles peuvent notamment être combinées avec des descriptions locales, conduisant ainsi à des représentations hybrides et complémentaires. Les résultats expérimentaux obtenus sur différentes bases d'images structurées permettent d'illustrer l'intérêt de cette approche pour la reconnaissance et la classification d'images.

Book excerpt: DES RECHERCHES PORTANT D'UNE PART SUR LA DEFINITION ET LA CONSTRUCTION DE NOUVELLES STRUCTURES DE VOISINAGES, ET D'AUTRE PART SUR LES TECHNIQUES DE RELAXATION, NOUS ONT CONDUITS A ABORDER SOUS UNE MEME APPROCHE LES PROBLEMES DE RECONNAISSANCE DES FORMES SUPERVISEE ET NON SUPERVISEE. CETTE APPROCHE REPOSE SUR UNE HYPOTHESE DE COHERENCE, SELON LAQUELLE DES ELEMENTS VOISINS DANS L'ENSEMBLE DE REPRESENTATION APPARTIENNENT LE PLUS SOUVENT A UNE MEME CLASSE, ET SON OBJECTIF EST D'EXPLOITER AU MIEUX POUR CHAQUE ELEMENT, L'INFORMATION CONTEXTUELLE APPORTEE PAR SON VOISINAGE. POUR LE CLASSEMENT, NOUS DEFINISSONS UN CRITERE GLOBAL QUI TIENT COMPTE A LA FOIS DE LA COHERENCE LOCALE ET DE LA FIDELITE AUX OBSERVATIONS. L'OPTIMISATION DE CE CRITERE CONDUIT A UN PROBLEME DE POINT FIXE DONT LA RESOLUTION PAR LA PROCEDURE DE GAUSS-SEIDEL ABOUTIT A UN REETIQUETAGE DE L'ENSEMBLE D'APPRENTISSAGE. LA DECISION FINALE EST PRISE A PARTIR DE CE NOUVEL ETIQUETAGE. CE MODELE PERMET D'UTILISER LA REGLE DE DECISION DES PLUS PROCHES VOISINS, AVEC EFFICACITE, LORSQUE L'ENSEMBLE D'APPRENTISSAGE EST DE PETITE TAILLE ET CONTIENT DES INDIVIDUS ATYPIQUES; CE QUI EST SOUVENT LE CAS EN SCIENCES HUMAINES.

Available in PDF, EPUB and Kindle. Book excerpt: Les modèles graphiques probabilistes sont un formalisme mèlant efficacement la théorie des graphes, permettant des représentations intuitives, et la théorie des probabilités, permettant la prise en compte d'incertitudes et d'imprécisions. La montée en puissance de ces modèles ces dernières décennies a abouti en l'attribution de la médaille Benjamin Franklin à Judea Pearl en informatique et sciences cognitives en 2008. Ce dernier a introduit les premiers algorithmes généraux de raisonnement dans l'incertain qui promettent des avancées majeures en traitement de l'information. Envisager les ordinateurs comme des machines pouvant découvrir par elle-mèmes des relations causales dissimulées au sein des millions d'observations disponibles dans les bases de données sans cesse alimentées automatiquement à travers le monde est devenue une réalité. L'utilisation des modèles graphiques impacte profondément l'intelligence artificielle ainsi que les statistiques appliquées. Ces modèles peuvent alors se révélés utiles dans les nombreux domaines applicatifs liés au traitement du signal et à l'apprentissage automatique, notamment sur la problématique d'extraction de connaissances.

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.
Download or read book Contemporary Criminological Issues written by Carolyn Côté-Lussier and published by University of Ottawa Press. This book was released on 2020-05-05 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary Criminological Issues tackles some of today’s most pressing social issues, from the criminalization of Indigenous peoples to interpersonal violence, border control, and armed conflicts. This book advances cutting-edge theories and methods, with the aim of moving beyond the scholarship that reproduces insecurity and exclusion. The breadth of approaches encompasses much of the current critical criminological scholarship, serving as a counterpoint to the growth of managerial and administrative criminologies and the rise of explicitly exclusionary and punitive state policies and practices with respect to ‘crime’ and ‘security.’ This edited collection featuring two books, one in English and one in French, includes important contributions to knowledge and public policy by eminent experts and emerging scholars. This book is published in English.
Download or read book Narratives of fear and safety written by Kaisa Kaukiainen and published by BoD - Books on Demand. This book was released on 2020-09-01 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: The essays in this edited volume, written in English and French, tackle the intriguing problems of fear and safety by analysing their various meanings and manifestations in literature and other narrative media. The articles bring forth new, cross-cultural interpretations on fear and safety through examining what kinds of genre-specific means of world-making narratives use to express these two affectivities. The articles also show how important it is to study these themes in order to understand challenges in times of global threats, such as the climate crisis. The main themes of the book are approached from various theoretical perspectives as related to their literary and cultural representations. Recent trends in research, such as affect and risk theory, serve as the basis for the discussion. The articles in the volume also draw from disciplines such as gender studies and trauma studies to examine the threats posed by collective fears and aggression on individuals' lives and propose ways of coping with fear. These themes are addressed also in articles analysing new adaptations of old myths that retell stories of the past. Many of the articles in the volume discuss apocalyptic and dystopian narratives that currently permeate the entire cultural landscape. Dystopian narratives do not only deal with future threats, such as totalitarianism, technocracy, or environmental disasters, but also suggest alternative ways of being and new hopes in the form of political resistance.

Download or read book Madness and Social Representations written by Denise Jodelet and published by Univ of California Press. This book was released on 1991-01-01 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: A striking account of a colony for the mentally ill that forces a reconsideration of madness in society. What happens when the mentally ill are not isolated from society but are instead welcomed into it and invited to take a place in the fabric of the community? Are fear and rejection replaced by the understanding and sympathy often engendered by familiarity? Or are the barriers between the sane and the mad only strengthened? We have experienced a taste of this scenario in the U.S. in the last decade with the new emphasis on de-institutionalization, but Denise Jodelet takes us to an extraordinary community in France where the mentally ill have assumed a visible and prominent role for more than seventy years. The small French town of Ainay-le-Ch�teau and its environs are the site of a "family colony" for men, established in 1900. Here the patients ("lodgers") live with ordinary families ("foster parents"), hold jobs, and are free to move about the countryside. Jodelet's chronicle of daily life in the colony is made rich and vivid by extensive ethnographic material as she unravels a complex set of relationships, ultimately finding that while some of the barriers between the "other" and the larger society have been overcome, new ones have arisen in their place. This unique social experiment provides invaluable social and cultural insights, illuminating many fundamental issues in psychology, psychiatry, and sociology.
Download or read book The Production and Distribution of Knowledge in the United States written by Fritz Machlup and published by Princeton University Press. This book was released on 1962 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Production and Distribution of Knowledge in the United States marked the beginning of the study of our postindustrial information society. Austrian-born economist Fritz Machlup had focused his research on the patent system, but he came to realize that patents were simply one part of a much bigger "knowledge economy." He then expanded the scope of his work to evaluate everything from stationery and typewriters to advertising to presidential addresses--anything that involved the activity of telling anyone anything. The Production and Distribution of Knowledge in the United States then revealed the new and startling shape of the U.S. economy. Machlup's cool appraisal of the data showed that the knowledge industry accounted for nearly 29 percent of the U.S. gross national product, and that 43 percent of the civilian labor force consisted of knowledge transmitters or full-time knowledge receivers. Indeed, the proportion of the labor force involved in the knowledge economy increased from 11 to 32 percent between 1900 and 1959--a monumental shift. Beyond documenting this revolution, Machlup founded the wholly new field of information economics. The transformation to a knowledge economy has resonated throughout the rest of the century, especially with the rise of the Internet. As two recent observers noted, "Information goods--from movies and music to software code and stock quotes--have supplanted industrial goods as the key drivers of world markets." Continued study of this change and its effects is testament to Fritz Machlup's pioneering work.

Download or read book Conceptual Basis Formalisations and Parameterization of the Stics Crop Model written by Nadine Brisson and published by Editions Quae. This book was released on 2009-01-19 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The STICS crop model has been developed since 1996 at INRA in collaboration with other research and technical institutes. The model syntheses, illustrates and concretizes an important part of the French agronomic knowledge as a point of view on the field and cropping systems working. The formalisations of the STICS crop model presented in this book can be considered as references used in the framework of crop sciences. The book arrangement relies on the way the model designs the crop-soil system functioning, each chapter being devoted to a set of important functions such as growth initiation, yield onset, water uptake, transformation of organic matter etc. One chapter deals with the cropping system and long term simulations and the final chapter is about the involvement of the user in terms of option choices and parameterization. If this book is mainly intended for scientists who use the STICS model, it can also be useful for agronomists, crop modellers, students and technicians looking for elementary formalizations of the crop-soil system functioning.
