Book excerpt: CE TRAVAIL PORTE SUR LA MODELISATION, LA SYNTHESE, L'ECHANTILLONNAGE ET L'ANALYSE DE SIGNAUX AUTO-SIMILAIRES ET A MEMOIRE LONGUE. L'APPROCHE RETENUE EST FONDEE SUR L'UTILISATION D'UNE CLASSE DE MODELES LINEAIRES NON-STATIONNAIRES. SA CONSTRUCTION REPOSE SUR L'AGREGATION DE CELLULES ELEMENTAIRES DU PREMIER ORDRE, DONT LES PRINCIPALES PROPRIETES SONT ETUDIEES. LES MODELES OBTENUS SONT COMPARES A CEUX DEJA EXISTANTS. LEUR DISCRETISATION CONDUIT A UNE METHODE DE SYNTHESE PAR DECOMPOSITION DE CHOLESKY. L'ECHANTILLONNAGE DE CES SIGNAUX EST UN PROBLEME TRES DELICAT. UNE SOLUTION CONCERNANT LE CHOIX PRATIQUE DES INSTANTS D'ECHANTILLONNAGE, BASEE SUR LE CALCUL DE LA BORNE DE RAO-CRAMER DES ESTIMATEURS DES PARAMETRES DE LA CELLULE ELEMENTAIRE, EST PROPOSEE. DEUX SCHEMAS D'ECHANTILLONNAGE SONT ENSUITE ETUDIES : REGULIER ET GEOMETRIQUE. ON DEVELOPPE ALORS DEUX ALGORITHMES D'ESTIMATION DES PARAMETRE DES MODELES, L'UN PAR MAXIMUM DE VRAISEMBLANCE, L'AUTRE PAR MAXIMUM DE VRAISEMBLANCE RECURRENT. LE MEMOIRE SE TERMINE PAR UN CHAPITRE DE VALIDATION DE CES ALGORITHMES QUI PRESENTE DE NOMBREUSES SIMULATIONS, SUIVI D'UN CHAPITRE QUI PROPOSE QUELQUES PERSPECTIVES A CE TRAVAIL.

Available in PDF, EPUB and Kindle. Book excerpt: LA TRANSFORMATION DE WIGNER-VILLE (TWV) EST UN OUTIL A PRESENT BIEN CONNU DANS L'ANALYSE DE SIGNAUX NON STATIONNAIRES. SA STRUCTURE NON LINEAIRE EST SOURCE D'INTERFERENCES ENTRE LES COMPOSANTES DU SIGNAL ANALYSE, CE QUI POSE UN PROBLEME LORS DE L'EXTRACTION DES INFORMATIONS PERTINENTES DANS L'IMAGE RESULTANTE. CONSIDEREE COMME UN PROCESSUS ALEATOIRE BIDIMENSIONNEL, CETTE IMAGE EST GENERALEMENT NON GAUSSIENNE. AINSI, CETTE TRANSFORMATION EST LE SIEGE DE TROIS NON-QUALITES: NON LINEARITE, DUE A L'OPERATEUR, NON STATIONNARITE ET NON GAUSSIANITE, QUI AFFECTENT LE SIGNAL ANALYSE OU PRODUIT. DANS CETTE ETUDE, NOUS NOUS INTERESSONS AUX DEUX NON-QUALITES LIEES AUX SIGNAUX: LA NON GAUSSIANITE, OU L'ON ABORDE CERTAINES TECHNIQUES UTILISANT LES STATISTIQUES D'ORDRE SUPERIEUR A DEUX, PUIS LA NON STATIONNARITE, QUI FAIT INTERVENIR LA TRANSFORMATION EN ONDELETTES COMME SECOND ROLE. ENFIN, DANS UN CADRE ETENDU DE LA TWV, ON RENCONTRE SIMULTANEMENT CES DEUX ATTRIBUTS. UN AUTRE ASPECT FONDAMENTAL DE CE TRAVAIL EST UNE CONTRIBUTION AU TRANSFERT DES TECHNIQUES DU TRAITEMENT DU SIGNAL VERS LE DOMAINE INDUSTRIEL, PAR LE DEVELOPPEMENT D'UN LOGICIEL D'ANALYSE NON STATIONNAIRE ET PAR SA MISE EN UVRE DANS L'ANALYSE VIBRATOIRE D'UN MOTEUR AUTOMOBILE

Available in PDF, EPUB and Kindle. Book excerpt: Les signaux non-stationnaires qui font l'objet de la thèse sont d'abord envisagés d'un point de vue général et traités par une approche temps-fréquence ; on étudie ensuite des signaux non-stationnaires répétitifs en faisant intervenir la sommation synchrone. L'étude des signaux non-stationnaires par des représentations temps-fréquence permet le suivi de l'évolution spectrale du signal au cours du temps. Nous avons étudié et amélioré certaines méthodes appartenant à la classe de Cohen en les identifiant à des lissages de la transformée de Wigner-Ville et en étudiant leurs propriétés dans le plan fréquence-fréquence. Nous avons opposé à ces lissages linéaires, d'autres dont les paramètres varient soit en fonction du contenu spectral du signal en chaque point du plan temps-fréquence, soit en suivant une loi de variation définie à priori. La transformée en ondelette de Morlet, qui appartient à cette dernière classe, a été étudiée et une modification a été proposée. Le caractère répétitif de certains signaux d'application tels que les potentiels évoqués ou les signaux cardiaques, nous a amené à concevoir de nouvelles méthodes d'estimation de retards entre les réalisations du signal. La qualité des estimateurs proposés permet tout d'abord d'améliorer le signal moyen. De plus une estimation suffisamment précise de l'écart-type du jitter permet d'envisager un réhaussement du signal moyen par déconvolution. Une analyse temps-fréquence sur les signaux moyens permet alors de façon plus précise de déceler les détails permanents d'une réalisation à l'autre. L'amélioration des techniques de sommation synchrone rend possible, en réduisant le nombre de signaux sommés, de suivre des variations dynamiques réellement observées. Un algorithme adaptatif LMS a été proposé et son équivalence avec le moyennage à pondération exponentielle a été établie

Download or read book Semiparametric Theory and Missing Data written by Anastasios Tsiatis and published by Springer Science & Business Media. This book was released on 2007-01-15 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes current knowledge regarding the theory of estimation for semiparametric models with missing data, in an organized and comprehensive manner. It starts with the study of semiparametric methods when there are no missing data. The description of the theory of estimation for semiparametric models is both rigorous and intuitive, relying on geometric ideas to reinforce the intuition and understanding of the theory. These methods are then applied to problems with missing, censored, and coarsened data with the goal of deriving estimators that are as robust and efficient as possible.

Available in PDF, EPUB and Kindle. Book excerpt: This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.
Download or read book Interaction and Market Structure written by Domenico Delli Gatti and published by Springer Science & Business Media. This book was released on 2000-03-27 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of essays which examine how the properties of aggregate variables are influenced by the actions and interactions of heterogenous individuals in different economic contexts. The common denominator of the essays is a critique of the representative agent hypothesis. If this hypothesis were correct, the behaviour of the aggregate variable would simply be the reproduction of individual optimising behaviour. In the methodology of the hard sciences, one of the achievements of the quantum revolution has been the rebuttal of the notion that aggregate behaviour can be explained on the basis of the behaviour of a single unit: the elementary particle does not even exist as a single entity but as a network, a system of interacting units. In this book, new tracks in economics which parallel the developments in physics mentioned above are explored. The essays, in fact are contributions to the analysis of the economy as a complex evolving system of interacting agents.

Download or read book Life Insurance Mathematics written by Hans U. Gerber and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: HaIley's Comet has been prominently displayed in many newspapers during the last few months. For the first time in 76 years it appeared this winter, clearly visible against the nocturnal sky. This is an appropriate occasion to point out the fact that Sir Edmund Halley also constructed the world's first life table in 1693, thus creating the scientific foundation of life insurance. Halley's life table and its successors were viewed as deterministic laws, i. e. the number of deaths in any given group and year was considered to be a weIl defined number that could be calculated by means of a life table. However, in reality this number is random. Thus any mathematical treatment of life insurance will have to rely more and more on prob ability theory. By sponsoring this monograph the Swiss Association of Actuaries wishes to support the "modern" probabilistic view oflife contingencies. We are fortu nate that Professor Gerber, an internationally renowned expert, has assumed the task of writing the monograph. We thank the Springer-Verlag and hope that this monograph will be the first in a successful series of actuarial texts. Hans Bühlmann Zürich, March 1986 President Swiss Association of Actuaries Preface Two major developments have influenced the environment of actuarial math ematics. One is the arrival of powerful and affordable computers; the once important problem of numerical calculation has become almost trivial in many instances.
