Cette thèse s’inscrit dans le cadre de la préparation de la mission spatiale franco­-chinoise SVOM (Space Variable Object Monitor) opérationnelle à l’horizon 2021 et qui aura pour but de détecter et caractériser les sursauts gamma. La première partie de la thèse consiste au développement d’un logiciel de simulation de COLIBRI (Catching OpticaL and Infrared BRight transIents), un télescope de suivi au sol de SVOM. Il comporte un simulateur de sursauts gamma, un exposure time calculator, un simulateur d'image, un algorithme estimant le redshift photométrique. Il a permis d'une part d’estimer les performances scientifiques du télescope afin de s'assurer qu'elles satisfont le cahier des charges, et d'autre part d'estimer une précision sur l'estimation de la distance du sursaut de l'ordre de 10% et 15% sur le redshift pour les sursauts à 3.5 < z < 8 et z > 8. La deuxième partie de la thèse porte sur l’étude de la propriété des poussières au sein des galaxies dans lesquelles se produisent ces sursauts gamma, mais aussi à l’étude de leur activité de formation stellaire. J'ai comparé les courbes d'extinction mesurées sur la ligne de visée de 7 GRBs à la courbe d'atténuation de leurs galaxies à l'aide d'un code de SED fitting, CIGALE. En comparant à un code de transfert radiatif on obtient des informations sur la distribution étoiles / poussière au sein de ces galaxies. Sur un échantillon élargi, on montre que les courbes d'atténuation pentues (plates) corrèlent avec des galaxies avec une faible (grande) atténuation due à la poussière, les moins (plus) activent en formation stellaire et les moins (plus) massives / This thesis lies within the framework of the sino-french SVOM (Space Variable Object Monitor) mission to be launched in 2021 whose objective is the detection and characterisation of Gamma-Ray Bursts (GRBs). The first part consists in the development of an end-to-end software for COLIBRI (Catching OpticaL and Infrared BRight transIents), a SVOM ground follow-up telescope. It consists in a GRB simulator, an Exposure Time Calculator, an image simulator and a photometric redshift algorithm. It allowed to estimate the telescope scientific performances to ensure that the optical design was fulfilling the scientific requirements. The relative accuracy on the photometric redshift delivered by COLIBRI is estimated to be about 10% and 15% for GRBs at 3.5 < z < 8 et z > 8. The second part of the thesis deals mainly with the study of dust properties in GRB host galaxies, but also with the star formation activity in these galaxies. We compare extinction curves measured along the GRB line of sight for 7 GRBs to the attenuation curve of their host galaxies measured with CIGALE, a SED fitting code. By comparing these curves to the results of a radiative transfer code, we obtain information about the geometrical distribution of dust and stars in these galaxies. On a larger sample of 23 galaxies, we show that the steepest (flattest) attenuation curves are associated to galaxies with a large (small) amount of dust attenuation, less (more) active in star formation and less (more) massive galaxies

Les ciments sulfoalumineux sont des liants hydrauliques qui, jusqu’aujourd’hui ne sont pas normalisés et ne possèdent donc pas une composition fixe. La teneur en ye’elimite – la phase principale de ce ciment- peut varier de 5 à 70 %. Or la composition du ciment sulfoalumineux (la composition du clinker ainsi que le pourcentage de gypse ajouté) est un paramètre critique qui contrôle sa réactivité, ses performances mécaniques, ainsi que sa durabilité. L’objectif principal de cette thèse est donc l’étude de l’influence de la composition des ciments sulfoalumineux sur leurs propriétés techniques, telles que les performances mécaniques et durabilité. Trois axes principaux ont été abordés. Tout d’abord une étude de l’influence de la composition du ciment sulfoalumineux (25-75 % en masse de ye’elimite) sur ses propriétés hydrauliques et mécaniques ainsi que sur la valeur limite en élément trace (Zn) a été menée. Dans ce but trois ciment sulfoalumineux (25, 50 et 75 % en masse de ye’elimite) ont été synthétisés. Ensuite l’effet de la variabilité de ce ciment sur sa durabilité dans l’eau pure et sulfatée a été investigué par rapport à un ciment sulfoalumineux commercial. Enfin, une étude des potentialités du ciment sulfoalumineux commercial à inhiber la réaction alcali silice dans les mortiers, lors de l’utilisation d’un granulat réactif (Silex), a été conduite. Il en résulte de cette étude qu’une augmentation de taux de ye’elimite dans le ciment sulfoalumineux engendre une augmentation des performances mécaniques. La valeur limite en Zn est de 0,3 % indépendamment de la composition du ciment sulfoalumineux. Par contre cette dernière influence la durabilité de ces ciments. Les résultats révèlent que même si la formulation contenant 75 % en ye’elimite confère les meilleures performances mécaniques, sa durabilité était la plus faible due à l’absence de stratlingite dans sa matrice cimentaire. Enfin, l’utilisation du ciment sulfoalumineux présente des bonnes potentialités à inhiber la réaction alcali silice. / Sulfoaluminate cements are hydraulic binders that, until today, are not standardized and therefore do not have a fixed composition. The content of ye'elimite - the main compound of this cement - can vary from 5 to 70 %. However, the composition of sulfoaluminate cement (clinker composition as well as the percentage of added gypsum) is a critical parameter that controls its reactivity, mechanical performance, as well as its durability. The main objective of this thesis is to study the influence of sulfoaluminate cements composition on their technical properties, such as mechanical performances and durability. Three main axes were discussed in this work. First, the influence of the sulfoaluminate cement composition (25-75 wt. % of ye'elimite) on its hydraulic and mechanical properties, as well as on the threshold limit of Zn, was studied. For this purpose three sulfoaluminate cements (25, 50 and 75 wt. % of ye'elimite) were synthesized. Then the effect of the variability of this cement on its durability in pure and sulphated water was investigated compared to a commercial sulfoaluminate cement. Finally, a study of the potentialities of commercial sulfoaluminate cement to inhibit the alkali silica reaction in mortars, when using a reactive aggregate (flint), was conducted. This study reveals that an increase in ye'elimite content in the sulfoaluminate cement increases the mechanical performance. The threshold limit of Zn is 0.3 % independently of the sulfoaluminate cement composition. Contrariwise, the sulfoaluminate cement composition influences the durability of these cements. Although the formulation containing 75 % of ye’elimite gives the best mechanical performances, its durability was lowest due to the absence of stratlingite in its cement matrix. Finally, the use of sulfoaluminate cement has good potential towards the inhibition of the alkali silica reaction.

[pt] A presente pesquisa examina imbricações entre performatividade e ideologia em relação à (re)produção de discursos heteronormativos sobre gêneros e sexualidades e maneiras de desestabilizar, ressignificar e subverter tais discursos limitadores. Nosso trabalho é guiado por um posicionamento queer que vê o gênero e a sexualidade como performances identitárias e não fatos naturais (BUTLER, [1990] 2003, [1993] 2002) e uma perspectiva linguística que considera as narrativas como uma maneira de intervir no social para mudar (ou reiterar) discursos ideológicos normatizantes e estigmatizantes (MOITA LOPES, 2008; THREADGOLD, 2005). Concentra-se sobre performances identitárias de gênero e sexualidade em narrativas digitais de praticantes de pegging, uma prática sexual na qual uma mulher usa um dildo segurado com um cinto para penetrar um homem (que se identifica como heterossexual) no ânus. O pegging é frequentemente alvo de preconceitos devido à associação ideológica heteronormativa entre o prazer anal dos homens e a homossexualidade (SÁEZ e CARRASCOSA, 2011) e à ideia que seja uma prática desviante relacionada com o BDSM (outro conjunto de práticas estigmatizadas) e, portanto, supostamente não íntimo. Nas narrativas e interações analisadas, fruto de uma etnografia virtual (HINE, 2000, 2005) na comunidade online Pegging 101, três temas principais surgiram: (1) as dificuldades dxs usuárixs em criar uma divisão nítida entre o que conta como pegging sensual ou BDSM, (2) visões diferentes da relação entre pegging e intimidade, incluindo a construção da intimidade a partir de compartilhar revelações ou de praticar a inversão de papéis e (3) problemas em lidar com a associação ideológica entre o prazer anal masculino e a homossexualidade. Embora o pegging tenha o potencial de ser uma prática subversiva que poderia contribuir para mudar concepções heteronormativas de gênero e sexualidade, nas narrativas a maioria dxs usuárixs da comunidade procurava ressignificar o pegging como uma prática normal, encaixando-o em discursos ideológicos heteronormativos sobre amor romântico e intimidade, e reforçava o binário de gênero e a masculinidade hegemônica. No processo de ressignificação, xs usuárixs da comunidade geralmente reiteravam certos discursos ideológicos heteronormativos na tentativa de subverter outros, particularmente, performando masculinidades que valorizavam a coragem ou a agressão como maneira de provar que não são homossexuais, ou reforçando estereótipos negativos sobre o BDSM nas suas tentativas de provar que o pegging pode ser algo íntimo. Desta maneira, ao estudar como discursos ideológicos heteronormativos são (re)produzidos performativamente nas narrativas digitais ao mesmo tempo que certas desestabilizações surgem, a presente pesquisa contribui para entender como fomentar uma política narrativa com mais discursos transgressores e menos reforços da heteronorma, produzindo mais rupturas e visibilizando possibilidades de discursos alternativos sobre gênero e sexualidade. / [en] The present study examines imbrications between performativity and ideology with regards to the (re)production of heteronormative discourses regarding gender and sexualities and to ways of destabilizing, resignifying and subverting such limiting discourses. Our research is guided by a queer position that sees gender and sexuality as identity performances and not natural facts (BUTLER, [1990] 2003, [1993] 2002) and a linguistic perspective that considers narratives to be a way of intervening in the social world in order to change (or reiterate) normalizing and stigmatizing ideological discourses (MOITA LOPES, 2008; THREADGOLD, 2005). It focuses on gender and sexuality identity performances in digital narratives of practitioners of pegging, a sexual practice in which a woman uses a strap-on dildo to penetrate the anus of a man (who identifies as heterosexual). Pegging is frequently the target of discrimination due to the ideological association between men s anal pleasure and homosexuality (SÁEZ e CARRASCOSA, 2011) and that idea that it is a deviant practice related to BDSM (another set of stigmatized practices) and, therefore, supposedly not intimate. In the narratives and interactions that were analyzed, stemming from virtual ethnography (HINE, 2000, 2005) in the online community Pegging 101, three principal topics emerged: (1) the users difficulties in creating a clear separation between what counts as sensual pegging or BDSM, (2) different views of the relationship between pegging and intimacy, including intimacy being created through revealing things about oneself or by practicing role reversal and (3) problems in dealing with the ideological association between male anal pleasure and homosexuality. Although pegging has the potential to be a subversive practice that could contribute to changing heteronormative conceptions of gender and sexuality, in their narratives, most of the community s users tried to resignify pegging as a normal practice, fitting it into ideological heteronormative discourses about romantic love and intimacy and reinforcing the gender binary and hegemonic masculinity. During the resignification process, the community s users usually reiterated certain heteronormative ideological discourses in their attempts to subvert others, in particular, by performing masculinities that valued courage or aggression as a way of proving they re not homosexual, or by reinforcing negative stereotypes about BDSM in their attempt to prove that pegging can be intimate. As such, by studying how heteronormative ideological discourses are performatively (re)produced at the same time as certain destabilizations emerge, this study contributes to understanding how to foster a narrative politics with more discourses that are transgressive and fewer ones that reinforce heteronormativity, creating more ruptures and visibilizing possibilities for alternative discourses about gender and sexuality.

[pt] A presente tese analisa, em uma perspectiva de múltiplos ciberespaços, performances identitárias de Vitória e Glória, mulheres em tratamento de câncer de mama que, através de suas interações online, constroem-se como vítimas ao descobrirem a doença e passam a agir como protagonistas em redes sociais, na luta contra o câncer. Sendo assim, os objetivos deste estudo são: (i) analisar as performances identitárias de duas mulheres com câncer de mama em diferentes sites; e (ii) compreender de que forma as participantes se constroem como protagonistas em redes sociais ao longo do tratamento da doença. A perspectiva teórica da pesquisa situa-se em estudos sobre as performances identitárias na narrativa e no discurso multimodal, no protagonismo discursivo e social e na teoria do posicionamento. A metodologia da pesquisa é qualitativa e interpretativa de cunho netnográfico. Os dados consistem de vídeos, entrevistas e narrativas das participantes que estão registradas em páginas públicas do Facebook, do YouTube, de três sites institucionais e de um blog. As análises indicam que: (i) há mudanças de performances identitárias e de posicionamento das participantes nas redes sociais, sinalizando transformação das trajetórias de vida ao longo de seus tratamentos – do ser comum ao protagonismo; (ii) as participantes ressignificam suas experiências de dor e lamentação, em uma perspectiva de discurso como ação social via discursos de emoção, esperança, triunfo e engajamento político; (iii) o agenciamento é direcionado aos interlocutores nas redes sociais, enquanto posicionamento político e identitário de enfrentamento do câncer. Nesse sentido, como contribuição social, esta tese sinaliza que, na sociedade contemporânea, as redes sociais se tornam espaços férteis de resistência e de empoderamento pessoal e de outros usuários, e espaços de metamorfose de lagarta a borboleta em relação ao câncer. / [en] The present thesis analyzes, from a multi-sited perspective, the identity performances of Vitória and Glória, women in treatment of breast cancer who, through their online interactions, construct themselves as victims when they discover the disease and begin to act as protagonists in social networks in the fight against cancer. Thus, the objectives of this study are: (i) to analyze the identity performances of two women with breast cancer in different websites; and (ii) to understand how the participants construct themselves as protagonists in social networks throughout the treatment of the disease. The theoretical perspective of the research is located in studies on the identity performances in narrative and multimodal discourse, in the discursive and social protagonism and in the theory of the positioning. The methodology of the research is qualitative and interpretative of a netnographic nature. The data consist of videos, interviews and narratives of the participants that are registered in public pages of Facebook, YouTube, three institutional websites and one blog. The analysis indicate that: (i) there are changes in identity performances and in the positioning of participants in social networks, signaling the transformation of life trajectories throughout their treatments - from being ordinary to protagonism; (ii) participants reassign their experiences of pain and lamentation, from a discourse perspective as social action through discourses of emotion, hope, triumph and political engagement; (iii) agency is directed to interlocutors in social networks, as a political and identity positioning for coping with cancer. In this sense, as a social contribution, this thesis indicates that, in contemporary society, social networks become fertile spaces of resistance and personal/users empowerment, and spaces of metamorphosis from caterpillar to butterfly in relation to cancer.

Master of Music / Department of Music / Frank C. Tracz / The following report is research and analysis of major wind band literature for the Graduate Conducting Recital performed by the Kansas State University Wind Ensemble on March 13th, 2011 under the direction of Lyle Sobba. The repertoire for the concert was comprised of the following pieces: Funeral March for Brass Choir by Edvard Grieg, Dance Mix by Rob Smith, and An Original Suite by Gordon Jacob. This examination, through thorough research and theoretical analysis, is a compilation of the documents created to effectively rehearse the compositions. The report also contains documents pertaining to the planning and executing of the Graduate Conducting Recital.

Master of Music / Department of Music / Gary Mortenson / This Master’s report focuses on analyzing the four works performed on the author’s Master’s recital on April 10, 2011, from a biographical, historical, theoretical, and technical standpoint. These works include André Jolivet’s Concertino for Trumpet, Oskar Böhme’s Concerto for Trumpet in F Minor, op. 18, Tomaso Albinoni’s Sonata á 6 con Tromba, and Manuel de Falla’s Suite of Old Spanish Dances.

Master of Music / Department of Music / Anna Marie Wytko / In 1838, Belgian instrument maker Adolphe Sax created the saxophone. The saxophone was officially patented on June 24, 1846. Sax became the first Professor of Saxophone at the Conservatoire de Paris. This conservatoire has been and continues to be a historically important school of music in Europe. There have been four saxophone professors at the Conservatoire National Supèrieur de Musique et de Danse de Paris since the instrument’s creation. These professors include: Adolphe Sax (1814-1894), Marcel Mule (1901-2001), Daniel Deffayet (1922-2002), and Claude Delangle (born 1957). Each instructor has championed the saxophone to new heights by refining pedagogical approaches and by advocating for the creation of new saxophone compositions. The music examined in this document represents pieces composed for each of the four saxophone professors who have taught at the Conservatoire de Paris. Paul-Agricole Génin’s composition Variations sur un thème espagnol: pour saxophone alto et piano was inspired by Adolphe Sax, Fernande Decruck composed Sonata in C-Sharp for Alto Saxophone and Piano (1943) for Marcel Mule, Ida Gotkovsky wrote Variations pathétiques: pour Saxophone Alto et Piano (1980) for Daniel Deffayet, and Sequenza IX for Alto Saxophone (1980) by Luciano Berio was dedicated to Claude Delangle. All of these pieces demonstrate how composers continually strive to expand the boundaries of the skilled saxophonists’ musical style, technical facility, and overall flexibility on the saxophone. This master’s report, presented as extended program notes, includes biographical information about the composers, a historical and stylistic overview of the selected compositions, and a harmonic and formal analysis of the music with respect to performance considerations.

Master of Music, Theater, and Dance / Department of Music, Theatre, and Dance. / David Littrell / This report provides detailed analyses of several orchestral works. Current orchestras have striven to rejuvenate their programs by balancing canonical literature with newer or less familiar works; such a practice has become especially important in an age when audiences are dwindling and orchestras are disbanding. The works included in this report follow that balanced blueprint, including staples such as Haydn’s Symphony No. 103 in E-flat Major (the “Drumroll”) and Berlioz’s “Hungarian March” from The Damnation of Faust to new orchestrations of 20th century works, such as Bryce Craig’s arrangement of the toccata from Ravel’s Le Tombeau de Couperin, as well as works composed within the last six years, such as Casey Cangelosi’s Concerto for Marimba and Orchestra No. 2. Each work’s formal design is straightforward, and the technical skills required are not virtuosic. The chapters below explore each work from a historical, theoretical, and performance perspective.

Ce projet s’inscrit dans le cadre de la phase de conception d’un pont autoroutier dans la province de Québec au Canada. Une des variantes proposées comporte la construction d’un tablier en béton précontraint par encorbellements successifs. Il est prévu d’utiliser un béton à hautes performances avec fumée de silice et avec air entraîné pour le tablier et les piles. La résistance à la compression visée est de 40 MPa à trois jours, rendue possible par l’adjonction de fumée de silice. Une campagne d’essais a été réalisée, d’une part pour élaborer une composition qui réponde aux critères de performance et d’autre part afin de caractériser le comportement mécanique et viscoélastique du BHP. Un essai de retrait et de fluage d’une durée de 16 mois a été réalisé, conformément aux recommandations du document TC107-CSP de la RILEM. Le BHP a été testé dans des conditions endogènes et de séchage, à plusieurs échéances de chargement soit 3, 7, 28 et 90 jours après le bétonnage. Comme le béton formulé pour le projet possède des caractéristiques peu communes, il convient de s’assurer que le BHP présente des déformations acceptables et qui peuvent être correctement prédites par les modèles réglementaires. Le retrait endogène, le retrait total le fluage propre et le fluage total sont mesurés avec un comparateur manuel et avec une corde vibrante placée au coeur des éprouvettes. Le modèle B4 de base prédit correctement les deux types de retrait. Après 16 mois, le retrait endogène du BHP s’élève 350 μm/m tandis que le retrait de séchage atteint 340 μm/m. Le retrait de séchage et le fluage de dessiccation ne semblent pas avoir atteint un palier final à la fin des essais. Le modèle de l’Eurocode 2 Annexe B prédit le mieux les deux types de fluage lorsqu’on considère qu’il n’y a pas de fumée de silice dans le modèle. Trois modèles ont été ajustés et extrapolés à très long terme : Eurocode 2 Annexe B, fib 2010 et le modèle B4. Les paramètres intrinsèques au matériau dans les équations de ces modèles sont optimisés et présentés dans le but d’être intégrés dans les calculs d’analyse et de dimensionnement du pont. Le fib 2010 ne semble pas adapté pour modéliser convenablement le fluage de dessiccation. Le modèle B4 ajusté avec les mesures de pertes d’eau prédit le fluage le plus important à 50 ans. Il parait néanmoins difficile de conclure sur une valeur finale à très long terme sans avoir effectivement atteint la fin du séchage pendant l’essai.
