L’enjeu actuel pour les fabricants de turboréacteurs est de fournir des moteurs peu polluants tout en assurant un rendement élevé. Une solution consiste en une réduction significative du jeu entre le rotor aubagé et le stator. Toutefois, le fonctionnement à jeu très faible induit inévitablement des contacts pouvant engendrer des pertes d’aubes. De nombreuses études identifiant les phénomènes vibratoires se sont révélées insuffisantes pour appréhender le problème de contact rotor-stator. Afin de franchir un cap dans la compréhension du contact, ces travaux de thèse proposent de considérer l’influence des phénomènes se produisant lors d’un contact frottant aube-carter : l’usure et le comportement thermomécanique.D’abord des résultats d’essais de contact aube-carter sur un banc à échelle réelle sont analysés permettant d’observer clairement l’usure du carter et les échauffements à l’échelle locale du contact.Afin d’expliquer ces observations expérimentales, des simulations numériques sont réalisées. Les études de la dynamique d’aube apportent une explication sur les profils d’usure du carter. Des simulations thermomécaniques montrent une influence significative des dilatations thermiques au contact.Enfin, une étude numérique couplée d’une aube en contact avec un carter est menée, considérant l’usure du carter induite par la dynamique de l’aube en contact, les échauffements et les dilatations thermiques se produisant au contact aube-carter. L’influence de ces phénomènes sur la dynamique de l’aube est clairement démontrée notamment les variations de régime vibratoire et les conditions pouvant entrainer la divergence du système. / The issue for the turbojet engine designers is to make less polluting et more efficient engine. A solution is to reduce significantly the clearance between the rotating bladed disk and the casing. However, operating with a very tight clearance induces inevitably interactions which can lead to loses of blades. Many studies identifying the vibratory phenomena are appeared as insufficient to totally understand the problem of contact. To reach a milestone this work proposes the study of the influence of the local phenomena during a blade-casing rubbing contact: wear and thermomechanical behavior.At first, the results of a study of a blade-casing contact performed on an experimental compressor of a turbojet at a real scale are analyzed in order to clearly identify the wear of the casing and the heating at the contact.Numerical simulations are preformed to explain these experimental observations. A study of the blade dynamics can explain the wear pattern of the casing. Thermomechanical simulations highlight a significant influence of thermal expansions on the contact.A numerical study of the dynamics of a blade interacting with a casing is performed with the consideration of the wear induced by the contact and the heatings and thermal expansions occurring at the local contact. It clearly highlights the influence of these phenomena on the blade dynamics, notably the variations of vibratory behavior and the conditions which can lead to the divergence of the system.

The purpose of this essay is to give a nuanced and problematized view of the notion that the literary universe of H.P. Lovecraft is purely nihilistic, in the most basic sense of the word, and instead try to show that it, in spite of this actually allows for both hope and growth for its characters. To do so, the essay will closely examine one of Lovecraft’s few recurring protagonists, Randolph Carter, who in relation to Lovecraft’s other characters, is much more on the outside of society than a part of it. To accomplish this, the essay will focus on those of Lovecraft’s texts which feature Carter and this one’s personal goals, philosophy and morals in relation to those of the society that surrounds him. Carter’s character and actions and ideals will throughout this be contrasted to the philosophical ideas of Friedrich Nietzsche to try to show that adherence to Nietzschean virtues can allow a character to actually transcend the supposed intrinsic nihilism and horror of Lovecraft’s universe. In examining Carter, central concepts will include, among other things: the search for beauty, the power of dreams as well as the power of passion, as well as Nietzschean concepts such as The Will to Power, Apollonian and Dionysian, The Eternal Return and Nihilism.

This analytical study of Elliott Carter's Piano Sonata focuses on middleground structural aspects found in the work such as phrases, phrase groupings, cadences and note collections. These are examined under four main headings: The Articulation of Phrases looks at the division of large passages into phrases, showing the various ways in which new phrases are marked. These include sudden changes in texture and register, restatements of thematic material, and recurring characteristics that appear at important cadential points. The Unification of Extended Passages by Middleground Stepwise Motion focuses on the rising linear motion that connects the individual phrases of many of these larger passages. Correlations between thematic material and phrase contours are also explored. The Relationship of Vertical Intervals and Note Collections to the Character and Phrase Rhythm of Particular Passages further examines phrase articulation by means of changes in note collections, with distinctions among phrases arising from the correlation of consonant vertical intervals with passages of linear motion and dissonant vertical intervals with passages that are more static. Anticipation and Overlapping of Materials describes an important aspect of the Sonata's overall structure in which themes and motives, as well as characteristic intervals of these materials are used to link the two movements of the work by a network of anticipations and flashbacks. An examination of the final climactic Maestoso section of the first movement (mm. 252-264) provides a summary of the various compositional aspects described in this study. / Arts, Faculty of / Music, School of / Graduate

Abstract Though a very influential Texan during the first half of the twentieth century, Amon Carter has yet to receive a full scholarly treatment, a problem which this dissertation attempts to rectify by investigating the narrative of Carter’s life to see how and why he was able to rise from humble beginnings to become a powerful publisher who symbolized boosterish trends within Texas and the New South. Publisher of the Fort Worth Star-Telegram, philanthropist, oilman, and aviation supporter, Carter used his power and influence to become a leading booster of his city and region seamlessly making the transition from being a business progressive to New Deal supporter to an Eisenhower Democrat. His connections with corporations like American Airlines and General Motors helped bring aviation and industry to his region, and his ability to work with public and private entities helped inspire his failed attempt to make the Trinity River navigable up to Fort Worth. His own success at building the Star-Telegram into the largest circulating newspaper in Texas encouraged him to expand his media empire into radio and television, while the wealth he gained from his oil activities enabled him to form a philanthropic foundation that would provide support for Fort Worth’s medical, cultural, and educational needs for the future. Possessing a life marked by both success and failure, it is clear throughout this dissertation that Carter embodied the idea of the New South civic booster, a figure who at once promoted his goals for his city and region while understanding how this fit within the larger national context.

Seminario para optar al título de Ingeniero Comercial, Mención Economía / Este seminario de título explora la naturaleza de la longevidad humana y su comportamiento estocástico, as como su incidencia en el cálculo de las pensiones de vejez. De acuerdo a esto, el estudio discute dos de las principales posturas sobre el límite de la supervivencia humana; desarrolla los distintos tipos de riesgo presentes en este problema financiero en el contexto de Rentas Vitalicias, y examina el tema de las tablas de mortalidad como principal instrumento regulador de reservas técnicas para las compañias de seguro. Posteriormente profundiza en modelos de predicción de mortalidad estocástica, presentando el Modelo Lee-Carter, y el Modelo de Cairns, Blake, Down (CBD). Además, se muestran aplicaciones empí ricas, de los modelos antes de nidos matemáticamente, desarrollando los casos de Italia a través del modelo Lee-Carter; Inglaterra y Gales, utilizando el modelo CBD; y finalmente el caso de Chile, donde la OECD realiza una comparación de las tablas de mortalidad con los dos modelos antes expuestos. Por ultimo, se discuten dos alternativas para resolver el riesgo de longevidad presente en el sistema de pensiones, proponiéndose por un lado los Bonos de Longevidad y, por otro, el Modelo de la Cuarta Edad.
