Abstract:
L'objectif de cette thèse est de réussir à utiliser des décompositions de graphes afin de résoudre des problèmes algorithmiques sur les graphes. Notre objet d'étude principal est la classe des graphes de Berge apprivoisés. Les graphes de Berge sont les graphes ne possédant ni cycle de longueur impaire supérieur à 4 ni complémentaire de cycle de longueur impaire supérieure à 4. Dans les années 60, Claude Berge a conjecturé que les graphes de Berge étaient des graphes parfaits. C'est-à-dire que la taille de la plus grande clique est exactement le nombre minimum de couleurs nécessaire à une color

Dans cette thèse on étudie les liens entre les récurrences topologique et géométrique et les volumes de Masur-Veech des espaces des modules des différentielles quadratiques et Abéliennes. On a choisi de s'intéresser aux graphes en rubans car ils peuvent être utilisé pour calculer les volumes de Masur-Veech. Dans le cas des graphes trivalents on propose une formule de récurrence géométrique, qui a été donnée indépendamment dans "On the Kontsevich geometry of the combinatorial Teichmüller space".

L’objet de cette thèse est de proposer des approches nouvelles permettant l’utilisation d’algorithmes d’apprentissage automatique travaillant usuellement des données tabulaires aux graphes.

Cette structure peut être représentée sous la forme d’une matrice, où chaque connexion entre de nœuds est représentée par une valeur non nulle, permettant une manipulation des données plus facile. Néanmoins, par leurs différences structurelles, la transposition d’un algorithme exploitant des données tabulaires aux graphe

We are now in an era where the technology has rapidly become democratized. The restrictions of relational databases to address the requirements of contemporary application domains, such as semantic web and social networking, where data has an inherited graph structure underlying in it, leads to the development of new technology called Graph Databases. Graph databases can be defined as those in which data structures for the schema and instances are modelled as graphs and data manipulation is expressed by graph-traversal operations.

Abstract:
This thesis explores the possibilities for ecocritical study in fiction through John Steinbeck’s 1939 novel The Grapes of Wrath. Major ecocritical interpretation has yet to gain much traction in novels; by focusing on human nature, this form’s “anthropocentric” posture seems itself to be antithetical to ecocritical efforts, which aim to unseat humans as the center of the moral universe. However, by analyzing The Grapes of Wrath’s formal, narratorial, and thematic valences, I argue that principles of social justice concurrently imply environmental justice in the philosophical currents of the te

Abstract:
The prevalence of graphs in emerging applications has recently raised a lot of research interests. To acquire interesting information hidden in large graphs, tasks including link prediction, collaborative recommendation, and reputation ranking, all make use of proximities between graph nodes. The discounted hitting time (DHT), which is a random-walk similarity measure for graph node pairs, has shown to be useful in various applications. In this thesis, we examine a novel query, called the multi-way join (or n-way join), over DHT scores. Given a graph and n sets of nodes, the n-way join retriev

Edmonds and Giles conjectured that the maximum number of directed joins in a packing is equal to the minimum weight of a directed cut, for any weighted directed graph. This is a generalization of Woodall's Conjecture (which is still open). Schrijver found the first known counterexample to the Edmonds-Giles Conjecture, while Cornuejols and Guenin found the next two. In this thesis we introduce new counterexamples, and prove that all minimal counterexamples of a certain type have now been found.

Abstract:
The Metric Travelling Salesman Problem, henceforth metric TSP, is a fundamental problem in combinatorial optimization which consists of finding a minimum cost Hamiltonian cycle (also called a TSP tour) in a weighted complete graph in which the costs are metric. Metric TSP is known to belong to a class of problems called NP-hard even in the special case of graph-TSP, where the metric costs are based on a given graph. Thus, it is highly unlikely that efficient methods exist for solving large instances of these problems exactly. In this thesis, we develop a new heuristic for metric TSP based on

The sum-product algorithm can not be operated on factor-graphs that contain loops. For these factor graphs iterative sum-product algorithm is used.

She becomes, then, an essential figure to the maintenance of the family's integrity. The aim of this study is to analyze the way in which the determination of new social values, especially th

Abstract:
The Darmstadt Internationale Ferienkurse für Neue Musik (IFNM) contributed to the rise of solo multiple percussion music and compositional techniques found in early repertoire, including graphic notation and indeterminacy. John Cage wrote the first solo multiple percussion work (27' 10.554" for a Percussionist) in 1956, two years before he became involved at the Darmstadt IFNM. Cage then delivered a lecture at the courses in 1958 about indeterminacy, and the next year (1959) Stockhausen composed the second work for solo multiple percussion—Nr. 9 Zyklus—for the IFNM. In the same year, Stockhaus

Abstract:
Depuis des décennies, le rôle joué par les joints de grains dans le comportement plastique des matériaux cristallins interroge mécaniciens, métallurgistes, spécialistes des matériaux. Après les avancées décisives de la plasticité individuelle des cristaux et de leur comportement collectif au sein d’agrégats, les effets complexes des interfaces sur le comportement effectif constituent l’enjeu restant à maîtriser. Car si les joints peuvent aussi bien être sites d’endommagement que réseau de consolidation dans une structure polycristalline, ils contribuent toujours fortement aux propriétés macros

Abstract:
La sonde atomique et la microscopie électronique ont été utilisées parallèlement afin d'étudier la microstructure et la composition des joints de grains rectilignes et dentelés d'un superalliage à base nickel Astroloy. Les microanalyses à la sonde atomique ont révélé une ségrégation de bore, molybdène et un peu de carbone aux joints homophases ou hétérophases, dentelés ou rectilignes. Un important enrichissement en chrome est également observé aux joints '/'. La quantification de la ségrégation intergranulaire a pu être réalisée en utilisant la sonde atomique tomographique.

La mise en evidence et l'interpretation du role benefique du carbone et du role nefaste de l'oxygene sur la cohesion intergranulaire du molybdene en l'absence de precipitation visible au meb constituaient le but de cette etude. Une methode efficace de purification du molybdene a ete mise au point. Les mesures de la concentration intergranulaire de carbone en fonction de la temperature de carburation et de la teneur volumique ont ete effectuees a l'aide d'un spectrometre auger. Un modele d'enrichissement des joints de grains au cours du refroidissement a ete propose. Les structures des joints p

Abstract:
Un des freins actuels a l'utilisation et au developpement des ceramiques techniques concerne les difficultes rencontrees dans la mise en forme de celles-ci. La mise en forme superplastique a haute temperature est un procede utilise industriellement pour les alliages metalliques dans le domaine aeronautique. Or les proprietes superplastiques des ceramiques ont ete mises en evidence depuis peu. L'objet de ce travail est ainsi d'etudier les capacites de deformation superplastique de composites ceramiques alumine zircone de tailles submicroniques et possedant une porosite residuelle apres frittage

Abstract:
Le zirconium et de titane sont des métaux de structure hexagonale. Ils présentent donc une plus faible symétrie cristalline que les métaux usuels (Fer, Aluminium,...) et par conséquent une anisotropie de propriété très marquée. Malgré cette forte anisotropie et les applications exigeantes dans lesquelles sont employés leurs alliages, les mécanismes de recristallisation et de changement de texture dans ces métaux ont été peu étudiés en comparaison de leurs homologues cubiques. L'étude de l'évolution de texture au cours du recuit après différents chargement initiaux nous a permis d'établir les m
