Book Description
L'IMPLANTATION PHYSIQUE DES RESEAUX DE NEURONES FORMELS EST RENDUE DIFFICILE PAR LE HAUT DEGRE DE CONNECTIVITE QUI LEUR EST INHERENT. CE TRAVAIL PORTE SUR L'ETUDE ET LA MISE AU POINT D'UN MONTAGE OPTO-ELECTRONIQUE D'UN RESEAU DE NEURONES FORMELS, QUI UTILISE LES POSSIBILITES DE L'OPTIQUE HOLOGRAPHIQUE POUR REALISER LES CONNEXIONS. NOTRE SYSTEME FONCTIONNE COMME UNE MEMOIRE ASSOCIATIVE, TRAITANT, EN PARALLELE, DES DONNEES BI-DIMENSIONNELLES, QUI, DANS NOTRE APPLICATION, SONT DES IMAGES DE CHIFFRES.

L'APPROCHE UTILISEE PERMET DE DONNER UNE INTERPRETATION EN TERMES DE CORRELATION ET DE RECONSTRUCTION DES TECHNIQUES DE LA PSEUDO-INVERSE. LA PARTIE CENTRALE DE CE TRAVAIL EST CONSACREE AU CODAGE DE L'HOLOGRAMME NUMERIQUE QUE NOUS UTILISONS POUR EFFECTUER LES CONNEXIONS ENTRE DEUX PLANS MATERIALISANT LES SORTIES ET LES ENTREES DES NEURONES.

Book Description
With the technical advancement of digital media and the medium of communication in recent years, there is a widespread interest in digital entertainment. An emerging te- nical research area edutainment, or educational entertainment, has been accepted as education using digital entertainment. Edutainment has been recognized as an eff- tive way of learning using modern digital media tools, like computers, games, mobile phones, televisions, or other virtual reality applications, which emphasizes the use of entertainment with application to the education domain. The Edutainment conference series was established in 2006 and subsequently - ganized as a special event for researchers working in this new interest area of e-learning and digital entertainment. The main purpose of Edutainment conferences is to facilitate the discussion, presentation, and information exchange of the scientific and technological development in the new community. The Edutainment conference series becomes a valuable opportunity for researchers, engineers, and graduate s- dents to communicate at these international annual events. The conference series - cludes plenary invited talks, workshops, tutorials, paper presentation tracks, and panel discussions. The Edutainment conference series was initiated in Hangzhou, China in 2006. Following the success of the first event, the second (Edutainment 2007 in Hong Kong, China), third (Edutainment 2008 in Nanjing, China), and fourth editions (Edutainment 2009 in Banff, Canada) were organized. Edutainment 2010 was held during August 16–18, 2010 in Changchun, China. Two workshops were jointly org- ized together with Edutainment 2010.

Book Description
Scattering theory deals with the interactions of waves with obstacles in their path, and low frequency scattering occurs when the obstacles involved are very small. This book gives an overview of the subject for graduates and researchers, for the first time unifying the theories covering acoustic, electromagnetic and elastic waves.

Book Description
Nonsmooth Optimization contains the proceedings of a workshop on non-smooth optimization (NSO) held from March 28 to April 8,1977 in Austria under the auspices of the International Institute for Applied Systems Analysis. The papers explore the techniques and theory of NSO and cover topics ranging from systems of inequalities to smooth approximation of non-smooth functions, as well as quadratic programming and line searches. Comprised of nine chapters, this volume begins with a survey of Soviet research on subgradient optimization carried out since 1962, followed by a discussion on rates of convergence in subgradient optimization. The reader is then introduced to the method of subgradient optimization in an abstract setting and the minimal hypotheses required to ensure convergence; NSO and nonlinear programming; and bundle methods in NSO. A feasible descent algorithm for linearly constrained least squares problems is described. The book also considers sufficient minimization of piecewise-linear univariate functions before concluding with a description of the method of parametric decomposition in mathematical programming. This monograph will be of interest to mathematicians and mathematics students.

Book Description
Memory Evolutive Systems; Hierarchy, Emergence, Cognition provides comprehensive and comprehensible coverage of Memory Evolutive Systems (MEM). Written by the developers of the MEM, the book proposes a mathematical model for autonomous evolutionary systems based on the Category Theory of mathematics. It describes a framework to study and possibly simulate the structure of living systems and their dynamic behavior. This book contributes to understanding the multidisciplinary interfaces between mathematics, cognition, consciousness, biology and the study of complexity. It is organized into three parts. Part A deals with hierarchy and emergence and covers such topics as net of interactions and categories; the binding problem; and complexifications and emergence. Part B is about MEM while Part C discusses MEM applications to cognition and consciousness. The book explores the characteristics of a complex evolutionary system, its differences from inanimate physical systems, and its functioning and evolution in time, from its birth to its death. This book is an ideal reference for researchers, teachers and students in pure mathematics, computer science, cognitive science, study of complexity and systems theory, Category Theory, biological systems theory, and consciousness theory. It would also be of interest to both individuals and institutional libraries. - Comprehensive and comprehensible coverage of Memory Evolutive System - Written by the developers of the Memory Evolutive Systems - Designed to explore the common language between sciences

Book Description
"Simon Denny's new body of work for Portikus ranks among the most ambitious the artist has developed to date. Over the period of one year, the artist researched and developed an intricate project that has grown to considerable dimensions -- both physically and in terms of its critical content. For two months, the monumental gallery space is turned into an homage to technology, communication, and the relentless need for innovation. Simon Denny has produced an embracing and multi-faceted installation that functions as a documentary of the South Korean technology giant Samsung and its global success story. The exhibition's title, "New Management", refers to the legendary management philosophy that Lee Kun-hee, Chairman of the Samsung Group, infamously introduced in the early nineties."--Publisher's website.
