Book excerpt: CETTE THESE PRESENTE UN SYSTEME D'AIDE A L'ANALYSE SPECTRALE DE SIGNAUX MONODIMENSIONNELS STATIONNAIRES DONT L'OBJECTIF FINAL EST D'AIDER UN UTILISATEUR A CHOISIR UNE METHODE D'ANALYSE APPROPRIEE AVEC DES PARAMETRES ADAPTES AU SIGNAL, AINSI QU'A REALISER UNE INTERPRETATION DU SPECTRE ESTIME LA PLUS COMPLETE POSSIBLE PAR RAPPORT AU DOMAINE D'APPLICATION ET A LA METHODE D'ANALYSE. LE SYSTEME D'AIDE PRESENTE ICI S'APPUIE SUR LA DEMARCHE D'UN EXPERT EN ANALYSE SPECTRALE QUI CONSISTE A VISUALISER LE SIGNAL A ANALYSER AINSI QUE SA FONCTION D'AUTOCORRELATION, AFIN D'EN RELEVER LA PERIODICITE AINSI QUE LE SUPPORT, ET A COMPARER LES DIFFERENTES ESTIMATIONS SPECTRALES EN TERMES DE MOTIFS ELEMENTAIRES ET DE TENDANCE GENERALE, ET NON EN TERMES DE VALEURS NUMERIQUES. UNE ETAPE DE PRE-ANALYSE A AINSI ETE DEFINIE DE MANIERE A ENRICHIR LA CONNAISSANCE DU SIGNAL A TRAVERS UN CERTAIN NOMBRE DE CARACTERISTIQUES EXTRAITES, A VERIFIER LA VALIDITE DES EVENTUELLES INFORMATIONS A PRIORI FOURNIES PAR L'UTILISATEUR, ET A INITIALISER AU MIEUX LES PARAMETRES DES DEUX ESTIMATEURS UTILISES AU COURS DE L'ETAPE D'ESTIMATION DU SPECTRE. CETTE ETAPE D'ESTIMATION EST BASEE SUR UNE ANALYSE PRIMAIRE FAISANT APPEL A DEUX ESTIMATEURS DE TYPE FOURIER, DONT LES PARAMETRES SONT INITIALISES A PARTIR DES CARACTERISTIQUES EXTRAITES LORS DE L'ETAPE DE PRE-ANALYSE, ET UNE ANALYSE SECONDAIRE, OU LE CHOIX DES ESTIMATEURS ET DE LEURS PARAMETRES ASSOCIES DEPEND D'UN OBJECTIF A ATTEINDRE. DES CRITERES DE CHOIX PERMETTENT DE VERIFIER A TOUT INSTANT L'EVOLUTION DE L'ANALYSE. ENFIN, UNE ETAPE DE TRANSFORMATION DES ESTIMATIONS SPECTRALES EN SYMBOLES, BASEE SUR L'EXTRACTION ET LA CLASSIFICATION DES MOTIFS ELEMENTAIRES ET DE LA TENDANCE GENERALE, PERMET D'AUTOMATISER L'INTERPRETATION DES COURBES, ET FACILITE LA COMPARAISON DES ESTIMATIONS AINSI QUE LA DESCRIPTION DU SIGNAL

This book was released on 1990 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE THESE PRESENTE UNE UNIFICATION DES TECHNIQUES D'ANALYSE SPECTRALE DE SIGNAUX MONODIMENSIONNELS STATIONNAIRES. CETTE UNIFICATION ISSUE DE L'ANALYSE PAR BANC DE FILTRES ASSOCIE A CHAQUE ALGORITHME UN FILTRE DONT LE CALCUL DES COEFFICIENTS EST OBTENU PAR MINIMISATION D'UNE FORME QUADRATIQUE SOUS CONTRAINTE. DE CE FAIT ON PEUT DEFINIR DEUX CLASSES DE METHODES ASSOCIEES A DEUX TYPES DE FILTRES DE COMPORTEMENT DIFFERENT, AINSI QU'UNE METHODOLOGIE MODULAIRE REGROUPANT LES ETAPES COMMUNES A DIFFERENTES METHODES. LA PREMIERE PARTIE DE CETTE THESE PRESENTE, SOUS CE POINT DE VUE, LES METHODES CLASSIQUES D'ANALYSE SPECTRALE BASEES SUR LA TRANSFORMEE DE FOURIER ET DES METHODES A HAUTE RESOLUTION. PUIS NOUS EXPLOITONS DES SIMULATIONS DONT L'OBJECTIF EST DE DEGAGER LES COMPORTEMENTS DE METHODES HORS DE LEUR DOMAINE D'HYPOTHESES. LA DEUXIEME PARTIE DE CETTE THESE EST CONSACREE A L'ETUDE D'UN SYSTEME EXPERT D'AIDE A LA CARACTERISATION FREQUENTIELLE D'UN SIGNAL. DANS UN PREMIER TEMPS NOUS SOULIGNONS L'INTERET QUE L'ON PEUT TIRER DE CONNAISSANCES A PRIORI OU DEDUITES SUR LE SIGNAL, PUIS NOUS PRESENTONS LA STRATEGIE (STATIQUE ET DYNAMIQUE) RETENUE POUR REALISER UN TEL SYSTEME

Available in PDF, EPUB and Kindle. Book excerpt: Permettre de concevoir, développer et utiliser des systèmes de diagnostic, de surveillance et de maintenance prédictive pour systèmes complexes (avions, centrales nucléaires, transport, etc.), afin d'optimiser les performances de la sûreté de fonctionnement : tel est l'objectif de cet ouvrage. Pour cela Fiabilité, diagnostic et maintenance prédictive des systèmes s'appuie sur la modélisation des systèmes (parties commandes et opératives), l'évaluation probabiliste et déterministe du fonctionnement, et la conception de systèmes de surveillance. Cet ouvrage fait le lien entre le diagnostic, la maintenance et la fiabilité des systèmes techniques, du plus simple au plus complexe. Son approche novatrice et sa présentation en font un véritable guide théorique et pratique pour les ingénieurs qui pourront y trouver la réponse à de nombreux problèmes de diagnostic, de surveillance et de maintenance, en particulier grâce à l'analyse vibratoire. Très didactique et accompagné de plus de 100 exercices et problèmes résolus reflétant des situations concrètes, il présente les concepts de base pour concevoir et développer correctement des outils ou des systèmes de diagnostic et de maintenance conditionnelle (prédictive) indispensables aux ingénieurs ou aux élèves ingénieurs en génie industriel, génie mécanique, robotique ou sûreté de fonctionnement dans les domaines les plus variés.

Download or read book Decision Control in Management Science written by Georges Zaccour and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision & Control in Management Science analyzes emerging decision problems in the management and engineering sciences. It is divided into five parts. The first part explores methodological issues involved in the optimization of deterministic and stochastic dynamical systems. The second part describes approaches to the model energy and environmental systems and draws policy implications related to the mitigation of pollutants. The third part applies quantitative techniques to problems in finance and economics, such as hedging of options, inflation targeting, and equilibrium asset pricing. The fourth part considers a series of problems in production systems. Optimization methods are put forward to provide optimal policies in areas such as inventory management, transfer-line, flow-shop and other industrial problems. The last part covers game theory. Chapters range from theoretical issues to applications in politics and interactions in franchising systems. Decision & Control in Management Science is an excellent reference covering methodological issues and applications in operations research, optimal control, and dynamic games.

Download or read book Perspectives in Control written by Dorothee Normand-Cyrot and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perspectives in Control comprises twenty-one essays by leading experts in the field of control. Most of these were presented as plenary lectures at the colloquium erspectives in Control held at Paris, June 1998, and organised by the GdR-Automatique to mark the occasion of the sixtieth birthday of its founder, Ioan Dori Landau. The book provides a unique opportunity to report the views of the world-renowned authorities on some of the directions in which control disciplines might evolve in various areas at the threshold of the twenty-first century. The variety of essays, which includes advanced methodological contributions and overview tutorials as well as more philosophical reflections, contributes to the richness of the book. Many aspects of the field are discussed , including: - adaptive control; - passivity concepts; - nonlinear control; - system identification; - supervisory control; - diagnosis; - emerging applied fields such as mechatronics, air traffic control, power plants, and educational devices. Many of the pioneering aspects of Professor Landau's work are covered. The book will be of interest to scientists as a guide to challenging research subjects, and of value to applied researchers as a survey of the current state of the art and potential of the field.
