Book Description
DANS LES SYSTEMES D'INTERROGATION FLEXIBLE, LES REQUETES PEUVENT RETOURNER DES DONNEES PLUS OU MOINS PERTINENTES. DE MANIERE GENERALE, CES SYSTEMES INTRODUISENT DES PREFERENCES DANS LES CRITERES DE REQUETES ET EVALUENT LA PERTINENCE DES DONNEES SUIVANT L'IMPORTANCE DES PREFERENCES QU'ELLES SATISFONT. CETTE THESE ETUDIE PLUS PARTICULIEREMENT L'INTERROGATION FLEXIBLE DANS LE CONTEXTE DES BASES DE DONNEES MULTIMEDIAS. NOUS MONTRONS TOUT D'ABORD SON INTERET LORSQU'UNE APPLICATION DOIT ACCEDER AU CONTENU RICHE ET COMPLEXE DES DONNEES MULTIMEDIAS. NOUS DEFINISSONS ENSUITE UN SYSTEME D'INTERROGATION FLEXIBLE GENERIQUE QUI INTEGRE LES CONCEPTS DE LA THEORIE DES ENSEMBLES FLOUS DANS L'ENVIRONNEMENT DES BASES DE DONNEES ORIENTEES OBJETS. APRES AVOIR COMMENTE L'INSERTION DE QUELQUES CLASSES D'OBJETS NECESSAIRES A NOTRE SYSTEME D'INTERROGATION, NOUS ETENDONS LES OPERATEURS DE REQUETES SELECTION, IMAGE, PRODUIT CARTESIEN, DESIMBRICATION ET GROUPEMENT POUR QU'ILS PUISSENT MANIPULER DES ENSEMBLES FLOUS D'OBJETS (ENSEMBLES CONTENANT DES ELEMENTS PLUS OU MOINS PERTINENTS) ET DES PREDICATS DE SELECTION FLOUS (PREDICATS POUVANT ETRE PLUS OU MOINS SATISFAITS). NOUS ETENDONS EGALEMENT OQL, UN LANGAGE DE REQUETES DECLARATIF. NOTRE TRAVAIL PRESENTE LA PARTICULARITE D'INTEGRER UNE ETUDE DETAILLEE DU TYPE DE DONNEES MULTI-ENSEMBLE FLOU. NOUS PROPOSONS AINSI UNE FORMALISATION DES OPERATEURS SUR MULTI-ENSEMBLES FLOUS EN UTILISANT TOUT D'ABORD LA REPRESENTATION PROPOSEE PAR YAGER PUIS UNE DEUXIEME REPRESENTATION BASEE SUR LA NOTION DE CARDINALITE FLOUE. ENFIN, LA THESE PRESENTE UNE EXPERIENCE DE MISE EN OEUVRE DE L'INTERROGATION FLEXIBLE SOUS L'ENVIRONNEMENT DE PROGRAMMATION SMALLTALK ET SOUS LE SGBD ORIENTE OBJET O2. NOUS AVONS APPLIQUE NOTRE MISE EN OEUVRE EN INTERROGEANT UNE BASE D'IMAGES ET EN PROPOSANT UNE EXTENSION DES RELATIONS D'ALLEN POUR INTERROGER UNE BASE DE VIDEOS.

Book Description
The refereed proceedings of the 10th International Fuzzy Systems Association World Congress, IFSA 2003, held in June/July 2003 in Istanbul, Turkey. The 84 papers presented together with 5 invited papers were carefully reviewed and selected form 318 submissions. The papers address all current issues in the area and present the state of the art in fuzzy sets, fuzzy systems, and fuzzy logic and their applications in a broad variety of fields. The papers are divided in four parts on mathematical issues, methodological issues, application areas, and cross-disciplinary issues.

Book Description
This book presents a specific and unified approach framework to three major components: Search Engines Performance, Link Analysis, and User’s Web Behavior. The book can be used by researchers in the fields of information sciences, engineering (especially software), computer science, statistics and management, who are looking for a unified theoretical approach to finding relevant information on the WWW and a way of interpreting it from a data perspective to a user perspective.

Book Description
The development of computational intelligence (CI) systems was inspired by observable and imitable aspects of intelligent activity of human being and nature. The essence of the systems based on computational intelligence is to process and interpret data of various nature so that that CI is strictly connected with the increase of available data as well as capabilities of their processing, mutually supportive factors. Developed theories of computational intelligence were quickly applied in many fields of engineering, data analysis, forecasting, biomedicine and others. They are used in images and sounds processing and identifying, signals processing, multidimensional data visualization, steering of objects, analysis of lexicographic data, requesting systems in banking, diagnostic systems, expert systems and many other practical implementations. This book consists of 16 contributed chapters by subject experts who are specialized in the various topics addressed in this book. The special chapters have been brought out in the broad areas of Control Systems, Power Electronics, Computer Science, Information Technology, modeling and engineering applications. Special importance was given to chapters offering practical solutions and novel methods for the recent research problems in the main areas of this book, viz. Control Systems, Modeling, Computer Science, IT and engineering applications. This book will serve as a reference book for graduate students and researchers with a basic knowledge of control theory, computer science and soft-computing techniques. The resulting design procedures are emphasized using Matlab/Simulink software.
