Les sous-graphes isométriques d'hypercubes (dit cubes partiels) constituent une classe centrale de la théorie métrique des graphes. Ils englobent des familles de graphes importantes (arbres, graphes médians, etc.), provenant de différents domaines de recherche, tels que la géométrie discrète, la combinatoire ou la théorie géométrique des groupes. Nous étudions tout d'abord la structure des cubes partiels de VC-dimension 2. Nous montrons que ces graphes peuvent être obtenus par amalgamations à partir de deux types de cellules combinatoires.Cette décomposition nous permet d’obtenir diverses caractérisations. En particulier, tout cube partiel de VC-dimension 2 peut être complété en cube partiel ample de VC-dimension 2. Nous montrons ensuite que les graphes de topes des matroïdes orientés et des complexes de matroïdes orientés uniformes peuvent aussi être complétés en cubes partiels amples de même VC-dimension.En utilisant un résultat de Moran et Warmuth, nous établissons que ces classes vérifient la conjecture de Floyd et Warmuth, l'une des plus vielles conjectures en théorie de l'apprentissage. C'est-à-dire qu'elles admettent des schémas de compression (étiquetés non propres) de taille leur VC-dimension.Par la suite, nous décrivons un schéma de compression étiqueté propre de taille d pour les complexes de matroïdes orientés de VC-dimension d, généralisant ainsi le résultat de Moran et Warmuth pour les amples. Enfin, nous fournissons une caractérisation par pc-mineurs exclus et parsous-graphes isométriques interdits des cubes partiels plongeables isométriquement dans la grille Z^2 et dans le cylindre P_n \square C_{2k} pour un certain n et k > 4Partial cubes (aka isometric subgraphs of hypercubes) are a fundamental class of metric graph theory. They comprise many important graph classes (trees, median graphs, tope graphs of complexes of oriented matroids, etc.), arising from different areas of research such as discrete geometry, combinatorics or geometric group theory.First, we investigate the structure of partial cubes of VC-dimension 2. We show that those graphs can be obtained via amalgams from even cycles and full subdivisions of complete graphs. This decomposition allows us to obtain various characterizations. In particular, any partial cube can be completed to an ample partial cube of VC-dimension 2. Then, we show that the tope graphs of oriented matroids and complexes of uniform oriented matroids can also be completed to ample partial cubes of the same VC-dimension.Using a result of Moran and Warmuth, we establish that those classes satisfy the conjecture of Floyd and Warmuth, one of the oldest open problems in computational machine learning. Particularly, they admit (improper labeled) compression schemes of size their VC-dimension.Next, we describe a proper labeled compression scheme of size d for complexes of oriented matroids of VC-dimension d, generalizing the result of Moran and Warmuth for ample sets. Finally, we give a characterization via excluded pc-minors and via forbidden isometric subgraphs of partial cubes isometrically embedded into the grid \mathbb{Z}^2 and the cylinder P_n \square C_{2k} for some n and k > 4

In this dissertation, a cost-effective message-based multiprocessor system which we call the Broadcast Cube System (BCS) has been proposed for solving important computation intensive problems such as, systems of linear algebraic equations and PDEs. A simulator for performance evaluation of parallel algorithms to be executed on the BCS has been implemented. A strategy (task assignment . algorithm) for assigning program tasks with precedence and communication constraints to the Processing Elements (PEs) in the BCS has been developed and its effectiveness demonstrated. This task assignment algorithm has been shown to produce optimal assignments for PDE problems. Optimal partitioning of the problems, solving systems of linear algebraic equations and PDEs, into tasks and their assignment to the PEs in the BCS have been given. Efficient parallel algorithms for solving these problems on the BCS have been designed. The performance of the parallel algorithms has been evaluated by both analytical and simulation methods. The results indicate that the BCS is highly effective in solving systems of linear algebraic equations and PDEs. The performance of these algorithms on the BCS has also been compared with that of their implementations on popular hypercube machines. The results show that the performance of the BCS is better than that of the hypercubes for linear algebraic equations and compares very well for PDEs, with a modest number of PEs despite the constant PE connectivity of three in the BCS. Finally, the effectiveness of the BCS in solving non-linear PDEs occurring in two important practical problems, (i) heat transfer and fluid flow simulation and (ii) global weather modeling, has been demonstrated.

Der volle Inhalt der QuelleAnnotation:
La thèse traite des arrêts non éclairés de cure psychothérapeutique, c'est-à-dire des interruptions définitives à l'initiative exclusive du patient ou de la patiente, sans discussion avec le clinicien ou la clinicienne. Pour la première fois, une telle étude est basée sur des témoignages de patient(e)s, recueillis lors d'entretiens cliniques après consentement éclairé. Au plan théorique, l'étude s'appuie sur une approche métapsychologique informationnelle originale de la psyché comme organe de modélisation du monde par la réalité psychique, inspirée par un historique de l'évolution des notions de projection et d'identification projective en psychanalyse. Pour l'ensemble du panel clinique de l'étude, les arrêts non éclairés de cure résultent systématiquement de la perte de confiance du patient en raison d'un trait disqualifiant imputé au clinicien par transfert objectal ou par identification projective, avec une conviction remarquablement forte, inébranlable et durable que le trait en question appartient effectivement à la personne du clinicien. Au terme de l'étude, il apparaît que les personnes ayant traversé des expériences traumatiques relationnelles dans leur enfance (rupture de continuité relationnelle avec l'environnement parental) pourraient être particulièrement exposées aux risques d'arrêts non éclairés lorsqu'elles entreprennent une psychanalyse ou une psychothérapie. En conséquence, l'étude propose des mesures de métacommunication préventive et curative visant à réduire un tel risque. Ces conclusions nécessiteraient d'être affinées par une recherche ultérieure plus large incluant notamment une comparaison avec une population témoin de patient(e)s n'ayant pas connu d'arrêts non éclairés dans leur(s) cure(s), afin de préciser davantage les spécificités des patient(e)s qui en provoquent et de mieux caractériser les traumatismes relationnels précoces dont ces dernier(e)s ont pu faire l'expérienceThis work is about unilateral treatment abortions by the patient, occurring without preliminary discussion with the therapist. For the first time, such a research is based upon testimonies from patients collected during clinical interviews with their informed consent. Theoretically, the study relies on an original informational approach of the psyche as an organ which models the outside world by the psychical reality, approach inspired by an historical survey of projection and projective identification psychoanalytical concepts evolutions. For the entire study sample, unilateral treatment abortion by the patient always derives from loss of confidence in the therapist caused by the attribution to him or her of a disqualifying feature through object transference or projective identification channel, with a remarkably strong, unwavering and long-lasting conviction that the disqualifying feature truly belongs to the therapist. At the end of the study, it appears that the persons who have had relational traumatic experiences during childhood (breaks in the continuity of relations with parental environment) would be particularly prone to unilateral treatment abortions during a psychoanalysis or a psychotherapy. Consequently, the study proposes preventive and curatives measures of metacommunication in order to reduce risk of treatment abortion. The conclusions of this study would require further wider research, involving particularly a control population of patients who never experimented unilateral treatment abortion during their psychoanalysis/psychotherapy, in order to more clearly identify the specificities of the patients who provoke such treatment abortions and the exact nature of the relational trauma which they may have experimented during childhood

Conselho Nacional de Desenvolvimento Científico e TecnológicoEsta dissertação reflete sobre os dilemas do socialismo contemporâneo a partir da experiência revolucionária cubana, focalizando especialmente a etapa conhecida como "atualização do socialismo". Em 2011 o VI Congresso do Partido Comunista de Cuba aprovou um conjunto de reformas econômicas cuja meta proclamada é a "atualização do modelo econômico e social" do país. Nestes termos, a proposta central do governo aponta para a diversificação dos atores econômicos e maiores níveis de descentralização, entretanto, sem abrir mão do predomínio da propriedade estatal sobre os meios de produção e da planificação sobre o mercado. Por outro lado, inegavelmente, essas medidas trazem mudanças significativas em relação ao modelo socialista historicamente construído em Cuba.

Data warehouses are being used in many applications since quite a long time. Traditionally, new data in these warehouses is loaded through offline bulk updates which implies that latest data is not always available for analysis. This, however, is not acceptable in many modern applications (such as intelligent building, smart grid etc.) that require the latest data for decision making. These modern applications necessitate real-time fast atomic integration of incoming facts in data warehouse. Moreover, the data defining the analysis dimensions, stored in dimension tables of these warehouses, also needs to be updated in real-time, in case of any change. In this thesis, such real-time data warehouses are defined as dynamic data warehouses. We propose a data model for these dynamic data warehouses and present the concept of Hierarchical Hybrid Multidimensional Data Space (HHMDS) which constitutes of both ordered and non-ordered hierarchical dimensions. The axes of the data space are non-ordered which help their dynamic evolution without any need of reordering. We define a data grouping structure, called Minimum Bounding Space (MBS), that helps efficient data partitioning of data in the space. Various operators, relations and metrics are defined which are used for the optimization of these data partitions and the analogies among classical OLAP concepts and the HHMDS are defined. We propose efficient algorithms to store summarized or detailed data, in form of MBS, in a tree structure called DyTree. Algorithms for OLAP queries over the DyTree are also detailed. The nodes of DyTree, holding MBS with associated aggregated measure values, represent materialized sections of cuboids and tree as a whole is a partially materialized and indexed data cube which is maintained using online atomic incremental updates. We propose a methodology to experimentally evaluate partial data cubing techniques and a prototype implementing this methodology is developed. The prototype lets us experimentally evaluate and simulate the structure and performance of the DyTree against other solutions. An extensive study is conducted using this prototype which shows that the DyTree is an efficient and effective partial data cubing solution for a dynamic data warehousing environment.

This thesis presents the mechanical characterization of fire resistant epoxy-hybrid resin systems suitable for ambient cure VARTM processes. Several new epoxy-hybrid nano-particle resins were developed and tested for use in large scale composite structures. Based on the viscosity, Tg, and cure time requirements twelve of these resins systems were pre-selected for mechanical testing. Neat resin castings were tested in tension to determine the elastic modulus, tensile strength and maximum elongation. From these results, six of the resin systems were further cast in unidirectional glass fiber laminates. Transverse tension and short beam shear testing was performed on all laminates to determine the mechanical properties of the glass/epoxy systems. Two of the epoxy-hybrid resin systems showed promising behaviors, having a higher transverse modulus and ultimate strength than the original benchmark vinyl-ester resin. Additionally, fiber Bragg grating sensors were embedded in one benchmark vinyl-ester laminate and one epoxy-hybrid laminate during the cure cycle. Taking advantage of both the extrinsic and intrinsic properties of these sensors, residual strains, temperature changes, and degree of cure of the resin were monitored. In addition to having a higher modulus of elasticity and ultimate strength, these new epoxy-hybrid nano-particle resin laminates showed minimal temperature increases during cure and smaller residual strains than the comparable vinyl-ester resin laminates.

Les dépendances fonctionnelles fournissent une information sémantique sur les données d'une table en mettant en lumière les liens de corrélation qui les unient. Dans cette thèse, nous traitons du problème de l'extraction de ces dépendances en proposant un contexte unifié permettant la découverte de n'importe quel type de dépendances fonctionnelles (dépendances de clé, dépendances fonctionnelles conditionnelles, que la validité soit complète ou approximative). Notre algorithme, ParaCoDe, s'exécute en parallèle sur les candidats, réduisant ainsi le temps global de calcul. De ce fait, il est très compétitif vis-à-vis des approches séquentielles connues à ce jour. Les dépendances satisfaites sur une table nous servent à résoudre le problème de la matérialisation partielle du cube de données. Nous présentons une caractérisation de la solution optimale dans laquelle le coût de chaque requête est borné par un seuil de performance fixé préalablement et dont la taille est minimale. Cette spécification de la solution donne un cadre unique pour décrire et donc comparer formellement les techniques de résumé de cubes de données.

Particle-based films are today an important part of various designs and they are implemented in structures as conductive parts, i.e., conductive paste printing in the manufacture of Li-ion batteries, solar cells or resistive paste printing in IC. Recently, particle based films were also implemented in the 3D printing technique, and are particularly important for use in aircraft, wind power, and the automotive industry when incorporated onto the surface of composite structures for protection against damages caused by a lightning strike. A crucial issue for the lightning protection area is to realize films with high homogeneity of electrical resistance where an in-situ noninvasive method has to be elaborated for quality monitoring to avoid undesirable financial and time costs. In this work the drying process of particle based films was investigated by high-frequency eddy current (HFEC) spectroscopy in order to work out an automated in-situ quality monitoring method with a focus on the electrical resistance of the films. Different types of particle based films deposited on dielectric and carbon fiber reinforced plastic substrates were investigated in the present study and results show that the HFEC method offers a good opportunity to monitor the overall drying process of particle based films. Based on that, an algorithm was developed, allowing prediction of the final electrical resistance of the particle based films throughout the drying process, and was successfully implemented in a prototype system based on the EddyCus® HFEC device platform presented in this work. This prototype is the first solution for a portable system allowing HFEC measurement on huge and uneven surfaces.

Dans cette thèse, nous essayons de développer de nouveaux outils pour la caractérisation des processus de mélange et ceci dans une approche lagrangienne. L’objectif est de trouver de l'information utile contenue dans la longue trajectoire d'une particule représentant un élément de fluide d'un écoulement turbulent. Les écoulements étudiés sont ceux induits par des turbines Rushton et à Pales inclinées dans une cuve agitée de 20 litres. Un dispositif expérimental utilisant des systèmes vidéo et d'analyse d'images a été développé pour suivre une petite particule, neutre de densité, dans trois dimensions spatiales pendant 1 heure. La qualité de suivi est testée par l'étude de sa densité de présence dans la cuve. La question principale est comment les champs de turbulences de vitesse s'impriment dans des propriétés géométriques et dynamiques des trajectoires. Par exemple, elles visualisent les courants de recirculation de l'écoulement secondaire et la présence des chicanes par leurs intersections avec des surfaces fictives de sections de Poincaré. Parmi les études se trouvent des analyses spectrales de quelques séries temporelles, différentes sortes de distributions lagrangiennes de longueurs, de temps et de vitesses, leurs valeurs moyennes et relations et leur dépendance vis-à-vis de la vitesse d'agitation. Cette information lagrangienne est comparée avec les caractéristiques plus classiques utilisées dans des cuves agitées comme le temps de recirculation. Les résultats montrent des différences significatives selon le type de mobile d'agitation utilisé ce qui souligne que la méthode de suivi de particule est prometteuse pour obtenir des signatures de l'action du mobile d'agitation et de la nature du réacteur dans le mélangeage

La gravite de la crise qui sevit a cuba n'a pas de precedents depuis la victoire de fidel castro. La desintegration de l'urss a mis a nu la structure maintenue de la monoculture sucriere. 35 ans apres la prise du pouvoir les ressources du pays ne permettent de garantir ni son approvisionnement energetique ni l'alimentation de la population. Tel est le bilan d'une integration dependante et subordonnee dans le comecon. La reintegration du pays dans l'economie mondiale va compromettre de nombreux acquis sociaux et remettre en cause le poids politique acquis par la havane sur la scene internationale. Les reformes economiques engagees en 1993 par fidel castro permettront-t-elles d'assurer une transition pacifique vers une economie de marche ou la crise politique est-t-elle inevitable ?There has never been such a severe crisis in cuba since fidel's castro victory. The demise of the soviet union which put and end to the previous relationship had revealed that the dependance of the economy on sugar crops remain steady. 35 years after castro's victory the resources of the country are not sufficient to guarantee neither the energetic needs of the country nor the food for the population. This is the balancesheet of the integration in the comecon which have put cuba in a subordinate and dependant status. The reinstatement of the country in the world economy will jeopardize its social achievements and the political influence la havana had won on the world scale. Will the economc reforms which have been initiated in 1993 by f. Castro be able to secure a peaceful transition towards a market economy or is a political crisis unavoidable ?

Convex cycles play a role e.g. in the context of product graphs. We introduce convex cycle bases and describe a polynomial-time algorithm that recognizes whether a given graph has a convex cycle basis and provides an explicit construction in the positive case. Relations between convex cycles bases and other types of cycles bases are discussed. In particular we show that if G has a unique minimal cycle bases, this basis is convex. Furthermore, we characterize a class of graphs with convex cycles bases that includes partial cubes and hence median graphs.

Particle simulations in real-time become reality only a few years before, when in computer science occured the idea of GPGPU. This new technology allows use the massive force of graphics card for general purposes. Today, the trend is to accelerate existing algorithms by rewriting into parallel form. On this priciple operate the particle systems too. An interesting area of particle systems are fluid simulations. The simulations are based on the theory of Navier-Stokes equations and their numerical solutions with SPH (Smoothed particle hydrodynamics). Liquids are part of everyday life, and therefore it is important to render them realistically. They are used in modern computer games and different visualizations that run in real time, therefore they must be quickly displayed.

Der volle Inhalt der QuelleAnnotation:
La formation, à partir de 1966, d’un groupe de quatorze poètes autour de la revue El Caimán Barbudo affiliée au Parti Communiste de Cuba a fait émerger un nouvel ethos littéraire. Nous l’appelons « soupçon ludique » pour la méfiance facétieuse qu’il provoque chez le lecteur. Quels sont les traits définitoires, les implications et les incidences idéologiques et esthétiques de cet ethos ? En s’appuyant sur les 48 recueils produits par les membres du groupe entre 1966 et 2002, année de sa dispersion définitive, sur 29 entretiens ainsi que sur le dépouillement de dix fonds d’archives situés à Paris, Madrid et La Havane, cette thèse montre d’abord que la naissance de leur écriture répond à une série d’injonctions politiques et esthétiques paradoxales : être une « avant-garde officielle », rebelle mais pas trop critique, marxiste mais lyrique. Après le renvoi éclair du groupe par le Parti en 1968 puis la forte censure du Quinquennat Gris (1971-1976), l’esprit ludique déserte leurs poèmes politiques devenus solennels et sérieux pour se replier dans la sphère amoureuse et érotique. Dans ces poèmes d’apparence inoffensive, la mise en scène parodique des identités de genre constitue une cri- tique voilée des identités politiques produites par la Révolution. À partir de 1991, la dissidence de plusieurs membres du groupe, sa recomposition partielle autour de la revue Encuentro de la cultura cubana fondée à Madrid en 1996 avec le soutien du gouvernement espagnol invitent à évaluer à nouveaux frais leur écriture : les dissidents quittent le soupçon ludique pour une écriture de la dénonciation qui thématise toutefois le jeu comme le symbole de leurs illusions perduesFrom 1966 onwards, the formation of a group of fourteen poets around the Cuban Communist Party-affiliated journal El Caimàn Barbudo created a new literary ethos named “playful suspicion” because of the mischievous mistrust it provokes in the reader. What are the defining traits, implications and ideological and aesthetic occurrences of this ethos? This dissertation was based on the 48 collections produced by the group members between 1966 and 2002 (year of its final dissolution), on 29 interviews, and on the examination of 10 archival holdings in Paris, Madrid and Havana. This dissertation first shows that the birth of their writ- ing responded to a series of paradoxical political and aesthetic demands: to be an “official avant-garde”, to be rebellious but not overly critical, to be both Marxist and lyrical. After the sudden dismissal of the group by the Party in 1968, then the harsh censorship of the five Grey Years (1971-1976), their playful spirit deserts the political poems which become solemn and serious, and withdraws to the romantic and erotic sphere. The parodic staging of gender identities in these seemingly harmless poems constitutes a veiled criticism of the political identi- ties produced by the Revolution. Starting in 1991, the dissent of several members of the group dissent and its partial recomposition around the journal Encuentro de la cultura cubana founded in Madrid in 1996 with the support of the Spanish government invites a new evaluation of their writing. The dissidents abandon playful suspicion in favor of denunciative writing, which nevertheless thematically places playfulness as a symbol of their lost illusions
En Cuba, a partir de 1966, se forma un grupo de catorce poetas en torno a la revista El Caimán Barbudo, afiliada al Partido Comunista nacional, generando un nuevo ethos literario que nosotros llamamos “sospecha lúdica”, por el recelo divertido que provoca en el lector. ¿Cuáles son los rasgos definotorios, las implicaciones y los impactos ideológicos y estéticos de este ethos? Para responder la tesis se basa en el estudio de los 48 poemarios escritos por los miembros del grupo entre 1966 y 2002, año de su desaparición, 29 entrevistas y 10 fondos de archivo sitos en Madrid, París y La Habana. El trabajo muestra en primer lugar que el naci- miento de esta escritura responde a una serie de requisitos políticos y estéticos paradójicos: ser una “vanguardia oficial”, rebelde pero no demasiado crítica, marxista pero lírica. En se- gundo lugar mostramos que, después del súbito desahucio del grupo por el Partido y la fuerte censura del Quinquenio gris (1971-1976), el espíritu lúdico deserta los poemas políticos, que se vuelven solemnes y serios, para replegarse en la esfera amorosa y erótica. En estos poemas aparentemente inofensivos, la paródica puesta en escena de identidades de género constituye une crítica velada de las identidades políticas producidas por la Revolución.

This study seeks to develop an investigation into the presence of revolutionary theory of Karl Marx in political sociology of sociologist Florestan Fernandes. With that overall goal, put as the central focus of the analysis the category “revolution” of Marxian thought and the way the Brazilian sociologist promotes a recovery of the concept in order to develop explanations about the socio-political processes that occurred in Brazil governed by military dictatorship and the period know as “democratization”. Still, led by this overview seeks to build an argument that identifies possible connections consistent continuity between what Marx described as “Communist” intellectual allies in the ideological-political to the working class, and advocacy and support offered by the Florestan “Cuban Revolution”, the struggle for democracy “social” and against the traditional conservatism of Brazilian politics, and his admission to the Workers’ Party (PT) and a parliamentary constituency. In suggesting a discussion of how a Brazilian Marxist articulates in his political action and the main political ideas that involve the revolutionary conception of Marx, the research proposal developed here attempts to answer, within its possibilities and limitations, what it meant to be Florestan a “revolutionary” in Brazil and the relationship that this position has the meaning given the term by Marx.CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior
O presente estudo procura desenvolver uma investigação sobre a presença da teoria revolucionária de Karl Marx na sociologia política do sociólogo Florestan Fernandes. Orientado por esse objetivo geral, põe como foco central da análise a categoria “revolução” do pensamento marxiano e a forma como o sociólogo brasileiro promove uma recuperação do conceito, a fim de elaborar explicações a respeito dos processos sócio-políticos que ocorreram no Brasil governado pela ditadura militar e no período que ficou conhecido como “redemocratização”. Ainda, conduzido por essa perspectiva geral busca construir uma argumentação que identifique possíveis nexos de continuidade coerente, entre o que Marx descreveu como “comunista”, intelectual que se alia no plano ideológico-político à classe trabalhadora, e a defesa e apoio oferecido por Florestan à “Revolução Cubana”, a luta pela democracia “social” e contra o tradicional conservadorismo da política brasileira, e o seu ingresso no Partido dos Trabalhadores (PT) como parlamentar constituinte. Ao sugerir uma discussão sobre como um marxista brasileiro articula em sua obra e ação política as principais idéias políticas que envolvem a concepção revolucionária de Marx, a proposta da pesquisa aqui desenvolvida intenta responder, dentro de suas possibilidades e limites, o que significou para Florestan ser um “revolucionário” no Brasil e a relação que essa posição tem com o sentido dado por Marx ao termo.

Cuando el general Prim accedió a la jefatura del Gobierno de España, en junio de 1869, tuvo que abordar varias cuestiones urgentes. De entre todas ellas, sobresalía por su complejidad la cuestión colonial.
En Cuba se estaba librando, desde octubre de 1868, una guerra agotadora entre independentistas cubanos y el ejército regular español. La cuestión de Cuba no se limitaba a una victoria o a una derrota de España; el futuro de Cuba afectaba a cuestiones subordinadas, como la esclavitud y el librecambio, asuntos vinculados al terreno económico. De acuerdo con su condición progresista, sus convicciones económicas y políticas, cercanas a la masonería, y los conocimientos que tenía del caso inglés, Prim quiso resolver el problema. Para ello, se mostró dispuesto a aceptar la independencia de la isla según determinadas circunstancias. Sobre todo, lo hizo porque previó un enorme espacio de influencia para España en el continente hispanoamericano, inaccesible mientras no se solucionase el conflicto cubano.When general Prim rose to the highest ranks of the Spanish government, in June of 1869, he had to resolve various urgent issues, one of which, was most pressing for its complexity, the colonial issue. Cuba was engaged in a grueling war, since October of 1868, between Cuban independists and the Spanish national army. The issue with Cuba was not simply about a victory or the defeat of Spanish arms, the future of Cuba was dependent upon additional issues, like slavery and free trade. Prim, influenced by his progressive political views, his convictions about freemasonry and the example of England, he wanted to resolve it and demonstrate that he was able to accept, under certain circumstances, the island´s independence. However, and above all, he did it because he envisioned a great opportunity for Spanish influence on the latin American continent, inconceivable until the resolution of the Cuban conflict.

Der volle Inhalt der QuelleAnnotation:
La carbonatation atmosphérique est un des facteurs les plus importants pour la durabilité du béton armé. Elle correspond à la diffusion du CO2 de l'atmosphère dans les pores du béton et à la dissolution des hydrates, notamment la portlandite Ca(OH)2, qui joue un rôle de tampon sur le pH. Lorsque la portlandite a été entièrement consommée, ou qu'elle n'est plus accessible, le pH chute à une valeur inférieure à 9. Ceci peut conduire à la corrosion des aciers du béton armé qui ne sont passivés et protégés qu'en milieu fortement basique. L'objectif de la thèse est de fournir une modélisation probabiliste physico-chimique de la carbonatation, prenant en compte les spécificités des process industriels et susceptible d'être utilisée pour un dimensionnement probabiliste des ouvrages. Une campagne d'essais a été menée afin de proposer une modélisation de la carbonatation pratique à utiliser en industrie. A partir de la nature du ciment, de la composition du béton, des caractéristiques du traitement thermique et de la cure, et d'au moins un essai de carbonatation (ou à défaut à partir de la résistance à la compression), le modèle de carbonatation élaboré permet d'estimer les profondeurs carbonatées pour différentes pressions partielles de dioxyde de carbone et de calculer l'indice de fiabilité correspondant. Enfin, une application de la méthodologie probabiliste montre la possibilité d'intégrer le dimensionnement probabiliste dans le contexte normatif pour optimiser la durabilité des produits préfabriquésAtmospheric carbonation is one of the most significant degradation factors for the durability of reinforced concrete structures. Carbonation relates to the diffusion of CO2 in the atmosphere through the concrete pores and to the dissolution of the hydrates, especially the portlandite, which supplies the reserve of concrete basicity. When portlandite is totally consumed, the pH value decreases to a value less than 9. It corresponds to the conditions allowing the corrosion of the reinforced bars which are protected only under a high pH level. The aim of this work is to carry out a probabilistic physico-chemical modelling of carbonation, taking into account the industrial requirements and being easy to utilize in a probabilistic design of the concrete cover. A wide experimental campaign was conducted in order to propose a practical model of carbonation for its efficient usage in the industry of precast concrete. From the cement nature, the concrete composition, the curing and thermal treatment characteristics, and one carbonation test (or at least the compressive strength), the model can determine the carbonated thickness for different pressures of CO2. Further, it allows the reliability index with respect to the initiation of corrosion to be estimated thanks to a link with a probabilistic algorithm. Following the scheme of checking the reliability level as recommended by the European regulation Eurocodes for structural design, the benefit of a probabilistic approach in the durability design of a concrete structure has been then emphasized

In my dissertation, I study a selection of little known Spanish and Cuban texts published during the Cuban War of Independence at the end of the 19th century. In this project, I provide a transatlantic approach of literary texts in various genres and subgenres, and political messages exchanged between Cuba and Spain, which have been neglected by scholars in the field.
By analyzing the emergence of a colonial discourse in the works of novelists, politicians and thinkers who wrote about the Cuban-Spanish confrontation, I establish their ambiguous and frequently contradictory colonial messages. In doing so, this dissertation furthers our understanding of the complexities of the political moment as well as the interest and ideals that ignited the conflict.
The study is of great relevance in view of the recent agreements between the United States and Cuba. The relations between the two countries are evolving in a way that was unthinkable at the beginning of the 20th century. Furthermore, secessionist feelings within the Spanish nation are reemerging and similar allegations and demands that brought Cuba to independence are in place. For all these reasons, it is necessary revisiting and comprehending the complex and, frequently contradictory, discourses that emerged in a moment, which was determinant for the development and future political attitudes of the three nations involved.

To quench a thermal runaway reaction in a chemical rector, an efficient approach is the introduction of a small quantity of a liquid inhibiting agent, named a “killer”, into the mixing vessel. In this thesis, an experimental approach has been coupled tightly with numerical modelling using Computational Fluid Dynamics (CFD). The first part of this thesis is devoted to a study of the hydrodynamics of partially-baffled mixing vessels, including the free-surface deformation caused by the central vortex. The use of an inhomogeneous, multiphase approach allowed simulation of the free-surface deformation. The capability of this novel method was demonstrated by very good agreement between the numerical predictions and experimental data. In the second part, liquid jet injection at the free-surface was coupled with the vessel hydrodynamics. Numerical results, obtained using an Eulerian-Lagrangian approach, have again shown good agreement with experimental data. These results allowed the jet trajectory to be modelled and its penetration into the agitated vessel was quantified. New mixing criteria were introduced that are specific to this application. Finally, the numerical methods validated at the pilot scale were applied at the industrial scale and allowed the proposal of practical improvements to the safety of the synthesis reactors studied

Given two Boolean functions, Boolean matching determines that if they are equivalent under input permutation and input/output phase assignment. In this thesis, we propose a NP-equivalence Boolean matching Algorithm. Three techniques involving “simultaneously partial assignment” and “redundant cube removal” and “redundant clause removal” are applied in our matching algorithm. Simultaneously partial assignment is to augment the minterms to cubes with don’t care inputs. Redundant cube removal is to use ZDDs as cache to filter the cubes which are duplicate or might be absorbed by others. Redundant clauses removal is to check whether the clause is redundant or not. The experimental results show that our matching algorithm is indeed effective and efficient.

The experimental results have been explained by integrated measurements combining phase characteristic of the St/VER/additive ternary system and Epoxy/curing agent /additive ternary systems before the cure, final cure conversion, glass transition temperature, SAXS and WAXS analysis, cured sample morphology and Mechanical properties. Also the scattering intensity of vinyl ester resin (VER) and unsaturated polyester (UP) with different structure in dilute styrene solution was measured by the method of small angle X-ray scattering (SAXS), and the radius of gyration of VER and the UP molecule can then be calculated by using the Guinier law.

The scattering intensity of vinyl ester resin (VER) with different structure in dilute styrene solution was measured by the method of small angle X-ray scattering (SAXS), and the radius of gyration of VER can then be calculated by using the Guinier law. Measuring the X-ray scattered intensity profile of the cured specimens for St/VER/GO (or TRGO) ternary system by using wide angle X-ray scattering (WAXS) allows one to investigate the change of d-spacing and the degree of dispersion of the substrate of functionalized graphene oxide (GO) or functionalized thermally reduced graphene oxide (TRGO) nanoplatelet. The structure of intercalated or exfoliated nanocomposites for the cured St/VER/GO (or TRGO) ternary system can then be identified.

In this study,silica nanoparticles(SNP) with a diameter ranging from15 nm to 60 nm were synthesized by size-controllable hydrolysis of elemental silicon, which can be used as a special additive for vinyl ester resins(VER) in the volume shrinkage control and mechanical property improvements . The effects of three other additives, including (1) nano-scale and submicron-scale core-shell rubber additive , (2) graphene oxide, and (3) thermally reduced graphene oxide . On the cure kinetics, glass transition temperature and X-ray scattering characteristics for the Styrene(St)/Vinyl ester resin(VER)/special additives ternary systems after the cure have also been investigated. The 15 nm silica nanoparticles was then given the surface treatment by the silane coupling agent, 3-methacryloxypropyltrimethoxysilane (γ-MPS),to obtain the MPS SiO2. In this work, the effects of MPS-SiO2 on the cured sample morphologies, and mechanical properties of the styrene(St)/ vinyl ester(VER)/MPS-SiO2 ternary systems during the cure have also been explored. The scattering intensity of vinyl ester resin (VER) with different chemical structure in dilute styrene solution was measured by the method of small angle X-ray scattering (SAXS), and the radius of gyration of VER can then be calculated by using the Guinier law. The phase separation of the cured St/VER/CSR ternary system can be studied by measuring the X-ray scattered intensity profile of the cured specimens for St/VER/CSR ternary system by using small angle X-ray scattering (SAXS). In addition, the chemical structures of functionalized graphene oxide (GO) and functionalized thermally reduced graphene (TRGO) were also characterized by Raman Spectroscopy (RS). Moreover, the reaction kinetics for the St/VER/special additive ternary or tetra system during the cure was measured by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR). Finally, based on the Takayanagi mechanical models, the glass transition temperature in each region of the cured samples for St/VER/special additive ternary system has been measured by dynamic mechanical analysis (DMA).
