This book was released on 1998 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: La reconnaissance de caracteres en milieu industriel est confrontee aux problemes de la variete des supports utilises (metal, bois, papier,) et du type d'ecriture (jet d'encre, gravure,). L'etude presentee porte sur la conception d'un systeme de reconnaissance de caracteres qui possede les proprietes d'autoadaptation necessaires a la resolution de ces problemes. Le systeme propose est elabore a partir de deux reseaux de neurones et d'une boucle de retroaction. Le premier reseau permet d'extraire un modele binarise invariant quels que soient le materiau et le type de marquage et quelles que soient la position, la taille et l'orientation du caractere. Il est construit suivant une architecture a couches structurees decrivant une operation de vision et une operation de normalisation. Un second reseau supervise du type rbf realise la classification de ce modele. Ce reseau a ete concu pour permettre et faciliter la reconnaissance multifonte en prenant compte de la variete et de la specificite des polices utilisees en marquage industriel. En fonction de la qualite de reconnaissance, le systeme peut grace a la boucle de retroaction, apporter au premier reseau l'information necessaire a l'amelioration de la vision des caracteres. La premiere partie est une introduction a la reconnaissance de caracteres et aux systemes d'ocr, nous presentons ensuite en deuxieme partie une bibliographie sur les reseaux de neurones utilises en classification et en troisieme partie quelques reseaux de neurones utilises en reconnaissance invariante. Dans une quatrieme partie, nous presentons l'architecture de notre systeme et detaillons les concepts originaux tels que la notion de centre/voisinage developpee dans l'etage de vision, l'architecture de normalisation et la notion de forme introduite dans la phase d'apprentissage du reseau rbf. La cinquieme partie est consacree a l'analyse des performances du systeme applique a des cas reels.

Available in PDF, EPUB and Kindle. Book excerpt: Ce livre est une contribution au th me de la commande pr dictive non lin aire r f renc e mod le et dans lequel sont adress es les probl matiques de l'identification par r seaux neuroniques, de la stabilit et de la poursuite des trajectoires dans l'espace d' tat. Concernant la mod lisation des syst mes dynamiques non lin aires, un algorithme bas sur les r seaux de neurones fonctions gaussiennes est pr sent et une technique pratique est propos e pour l'identification des mod les NARX et d'autres structures neuroniques r troaction externe, capables de restituer les propri t s dynamiques et de stabilit du syst me nonlin aire identifi . les caract ristiques dynamiques de ces structures neuroniques permettent leur int gration dans des sch mas de commande pr dictive non lin aire assurant la stabilit en boucle ferm e. La stabilisation de la poursuite des trajectoires dans l'espace d' tat est assur e par une architecture de commande caract re hybride: pr dictive-neuronique.

Available in PDF, EPUB and Kindle. Book excerpt: A collection of scholarly essays, Complexity Theory and thePhilosophy of Education provides an accessible theoreticalintroduction to the topic of complexity theory while consideringits broader implications for educational change. Explains the contributions of complexity theory to philosophyof education, curriculum, and educational research Brings together new research by an international team ofcontributors Debates issues ranging from the culture of curriculum, to theimplications of work of key philosophers such as Foucault and JohnDewey for educational change Demonstrates how social scientists and social and educationpolicy makers are drawing on complexity theory to answer questionssuch as: why is it that education decision-makers are so resistantto change; how does change in education happen; and what does ittake to make these changes sustainable? Considers changes in use of complexity theory; developedprincipally in the fields of physics, biology, chemistry, andeconomics, and now being applied more broadly to the socialsciences and to the study of education

Available in PDF, EPUB and Kindle. Book excerpt: The book offers important insight relevant to Corporate, Governmentand Global organizations management in general. The internationallyrecognised authors tackle vital issues in decision making, howorganizational risk is managed, how can technological andorganizational complexities interact, what are the impediments foreffective learning and how large, medium, and small organizationscan, and in fact must, increase their resilience. Managers,organizational consultants, expert professionals, and trainingspecialists; particularly those in high risk organizations, mayfind the issues covered in the book relevant to their daily workand a potential catalyst for thought and action. A timely analysis of the Columbia disaster and theorganizational lessons that can be learned from it. Includes contributions from those involved in the InvestigationBoard report into the incident. Tackles vital issues such as the role of time pressures andgoal conflict in decision making, and the impediments for effectivelearning. Examines how organizational risk is managed and howtechnological and organizational complexities interact. Assesses how large, medium, and small organizations can, and infact must, increase their resilience. Questions our eagerness to embrace new technologies, yetreluctance to accept the risks of innovation. Offers a step by step understanding of the complex factors thatled to disaster.

Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage, devenu célèbre sous son sigle MCSE, a déjà été utilisé par plus de 50 000 étudiants, chercheurs, professionnels. L'objectif est de lire et écrire des textes en anglais scientifique avec facilité et pertinence. L'ouvrage est conçu pour que l'apprenant devienne un véritable utilisateur de l'anglais. La méthode originale repose sur l'analyse des fonctions et structures nécessaires : measurement, frequency, comparison, modification, link words, time, cause and consequence, hypothesis, modality, purpose and process, impersonal forms, compound nouns and adjectives. Dans chaque unit, des tests d'auto-évaluation permettent de se situer et de construire son parcours de formation, d'abord en définissant ses objectifs à l'aide des key points et du lexis, puis, de façon plus personnalisée, en puisant dans les examples in context, checkpoints (back to basics, word web), web search, FAQs... MCSE est l'outil de base d'une méthode qui comprend aussi d'autres outils dans la même collection (Listening Comprehension for Scientiflc English et Speaking Skills in Scientitic English). L'ouvrage est destiné à tout apprenant de niveau baccalauréat qui désire acquérir une réelle compétence dans l'écriture et la lecture de textes en anglais scientifique.

Download or read book An Introduction to Differential Manifolds written by Jacques Lafontaine and published by Springer. This book was released on 2015-07-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.
