The aim of this paper is to examine how heterosexual cis-females is affected by living in an abusive relationship, in terms of how they act and relate to themselves, their environment and their abusers. Based on Sara Ahmed's phenomenology and her theory of how bodies are oriented towards the outside world, depending on previous experience and social discourses, two interviews with two heterosexual cis-women who lived through violent relationships where conducted, and through their narratives I examine how they orient themselves as a result of the abusive relationship. The women reports a (dis)orientation toward themselves and away from the abuser, as well as friends and family as a result of feelings of shame, anxiety and fear induced by the abusive relationship. The women also describe how some feelings of anxiety "sticks" and is ”re-lived” by the abused even when the relationship has ended, exposing the relationship as deeply disorienting.

Ahmed Adnan Saygun (1907-1991) was one of Turkey's most prominent composers, described in The Times obituary as "the grand old man of Turkish music, who was to his country what Sibelius is to Finland, what de Falla is to Spain and what Bartók is to Hungary" (15 January 1991). Yet so far Saygun's life and works have never been the subject of a critical study in or outside Turkey. This thesis aims to create a comprehensible picture of his life and music for the first time. Divided into three parts, Part I of the thesis presents an annotated biography, preceded by a short introductory survey on the state of European music within the Ottoman Empire, which was significant in Saygun's upbringing. Taking as source material scattered newspaper articles, interviews and hitherto unpublished letters and a diary belonging to the composer, Part I focuses on Saygun's musical upbringing in Izmir and his subsequent education in Paris under Vincent d'Indy at the Schola Cantorum between 1928 and 1931. Also amongst the issues that are addressed here is the important role Saygun played in the musical life of the country on his return to Turkey from Paris, which was being rapidly transformed under Kemal Atatürk's reform movement; his enthusiasm for Turkish folk-music which led to a collaboration with Bela Bartók that finally culminated in the latter's celebrated field-trip to Anatolia in 1936 and his friendship with Michael Tippett, drawn from Tippett's original unpublished letters. The thesis shows that Saygun was not only responsible for training future musicians of Turkey in Western compositional techniques, but also himself wrote works in line with the country's modem music policy which took the principles of European polyphonic music as a model. As a prolific composer Saygun's output comprised five operas, five symphonies, three string quartets, five concertos and a wide range of chamber and choral music. Taking selective works, Part II looks at his developing style, beginning with the influence of the Schola Cantorum education and the effects of the music policy of the early republican years on his output and establishes him as the national composer of Turkey. Works discussed include the oratorio Yunus Emre (1942), his most celebrated work, which immediately became a symbol of the music reforms and was subsequently conducted by Leopold Stokowski in New York in 1958, the first two string quartets, the first two symphonies and the two piano concertos. Part III is a catalogue raisonné which has been compiled through evaluating existing lists of works and going through all the autograph manuscript scores of the composer that are housed at the Bilkent University Adnan Saygun Archives in Ankara. Since Saygun's works have never been systematically catalogued before, the information given here includes dates of composition, instrumentation, duration, dedication, location of manuscripts, publication and recording details, as well as translations of hitherto unpublished analytical notes on certain works written by the composer.

Aujourd’hui, la politique européenne incite les industriels de l’automobile à concevoir des véhicules “propres”, ainsi des normes de plus en plus contraignantes visant notamment à réduire les émissions de gaz à effet de serre ont vu le jour. Les ingénieurs sont donc amenés à envisager des solutions innovantes basées sur le contrôle des écoulements, en particulier celui des décollements puisqu’ils ont généralement des effets délétères sur les performances aérodynamiques. En effet, les phénomènes de décollement, inhérent aux corps épais, sont à l’origine de l’augmentation de la traînée et par conséquent de la consommation de carburant. Les travaux présentés dans ce mémoire sont dédiés au contrôle d’écoulement en vue de la réduction de traînée sur un modèle générique de véhicule automobile appelé “Corps de Ahmed” par une combinaison d’actionneur de type jets ynthétiques. Le mémoire s’articule autour de deux axes principaux. Le premier a permis la caractérisation d’actionneurs de type jets synthétiques, les fréquences et amplitudes optimales au regard de différents critères ont ainsi été identifiées et analysées. Le second a été consacré à étudier la réponse des structures décollés à des perturbations périodiques localisées afin de poursuivre la compréhension de la physique impliquée dans le contrôle de la traînée aérodynamique. / Nowadays, the car manufacturers are forced by the european policy to follow more and more strict rules concerning the design of “clean” automotives, in order to reduce the gas emissions responsible for the greenhouse effect. The engineers have to consider innovative solutions based on flow control, particularly for flow separation which generally has deleterious effects on aerodynamic performance. Indeed, the separation phenomena, inherent to the bluff bodies, are at the origin of thedrag increase and consequently of the fuel consumption. The work presented in this thesis is dedicated to combinated flow separation control from simplified hatchback geometry (Ahmed body) by a synthetic jet. The thesis focuses on two main axes. The first axis has allowed the characterization of synthetic jets actuators, the frequencies and the optimal amplitudes with regard to various criteria were so identified and analyzed. The second axis was dedicated to study the separation flow structures response from local periodic disturbances in order to pursuing the physics knowledge involved in the aerodynamic drag control.

De nouvelles connaissances sur les écoulements autour des véhicules automobiles doivent aujourd'hui être apportées pour envisager une amélioration de leurs performances aérodynamiques. Ce travail de thèse repose sur des études expérimentales, réalisées en soufflerie, permettant l'analyse et la compréhension des mécanismes physiques associés aux écoulements décollés tridimensionnels et instationnaires se développant à l'arrière des véhicules automobiles. Il se concentre plus particulièrement sur la géométrie générique du corps de Ahmed permettant de reproduire les écoulements à l'arrière de véhicule de type bicorps (lunette arrière et culot). L'étude compare deux maquettes de géométrie différente dont l'une permet d'obtenir une zone de recirculation tridimensionnelle sur la lunette arrière et l'autre de conserver l'écoulement attaché. L'analyse et la comparaison des topologies moyennes des écoulements permettent d'évaluer les interactions entre la recirculation 3D et les autres structures en présence. On montre plus particulièrement que l'absence du décollement sur la lunette arrière modifie la topologie de l'écoulement à l'arrière du culot avec une réduction de traînée de l'ordre de 10%. Les résultats montrent que les effets de la recirculation ne sont pas assez importants pour modifier la position des structures tourbillonnaires longitudinales se développant sur les arêtes latérales de la lunette, mais modifient légèrement leur intensité. L'analyse spectrale des fluctuations de vitesse et de pression indique que la recirculation est le siège d'activités instationnaires pseudopériodiques. La Décomposition Orthogonale Propre des champs de vitesse et de pression montre finalement que ces activités sont associées à un mécanisme de battement de la recirculation passant d'une configuration décollée à une configuration attachée et à une émission de structures tourbillonnaires formées par la couche cisaillée de la recirculation. / More and more knowledge related to flows behind road vehicles must be provided to improve their aerodynamic performances. This PhD thesis deals with experimental studies carried out in a wind tunnel, and enables analysis and understanding of physical mechanisms related to three-dimensionnal and unsteady separated flows that develop behind road vehicles. More specifically, it focuses on the generic model of Ahmed body that recreates flows behind common fastback cars (rear window and rear part). This study compares two models with different shape, the first one having a sharped edge between the roof and the rear window enabling the development of a separated region, and the second one having a rounded edge preventing separation. Analysis and understanding of the time averaged topology of both flow configurations are performed to characterize interactions between the three-dimensionnal separation and the other structures. More specifically, it is observed that suppressing separated region over the rear window changes the flow topology behind the rear base with a drag reduction of approximately 10%. Results show that the influence of the separated region is not strong enough to modify the location of the longitudinal vortical structures, which develop at each side of the model, but is strong enough to slightly modify their intensity. Spectral analysis of the velocity and pressure fluctuations indicates that the separated region is characterized by pseudo-periodic unsteady activities. Proper Orthogonal Decomposition of instantaneous velocity and pressure fields shows that these activities are respectively related to a flapping mechanism of the separated zone moving between a shrinked state and an enlarged state, and a large scale vortices emmission resulting from the shear layer of the separated region.

La réduction de la résistance à l’avancement par des techniques de contrôle active sera une nécessité d’importance croissante dans les années à venir pour le secteur des transports. Cette thèse fait partie d’une nouvelle voie de recherche consistant à utiliser des décharges plasmas à pression atmosphérique pour modifier les écoulements en vue d’améliorer les performances aérodynamiques (diminution de la traînée et augmentation de la portance). L’actionneur retenu est une décharge à barrière diélectrique surfacique avec un diélectrique composé d’une combinaison de deux matériaux polymères souples. L’écoulement induit par l’actionneur plasma, appelé vent ionique, est d’abord étudié expérimentalement dans l’air au repos en fonction du régime de la décharge. Une loi empirique liant la vitesse du vent ionique à la tension et à la fréquence de l’alimentation est proposée. De cette loi se dégagent une vitesse et une longueur caractéristiques utilisées pour prédire les principales propriétés du jet de paroi induit en aval de la décharge (lois d’échelle). L’efficacité de l’actionneur est ensuite testée en soufflerie subsonique pour trois configurations aérodynamiques de complexité croissante : couche limite laminaire non décollée (plaque plane), couche limite turbulente décollée (profil épais) et couche limite décollée 3D (corps de Ahmed, lunette inclinée à 25°). Des résultats significatifs tant sur le plan de la modification de la topologie de l’écoulement que de l’amélioration des efforts aérodynamiques sont obtenus pour des nombres de Reynolds jusqu’à 1,7.106 (35 m/s). / Active flow control is a key issue to meet the environmental requirements for the next generations of aircrafts and cars. The aim of this work is to study subsonic airflows control by plasma actuators in order to improve aerodynamic performances (drag reduction and lift enhancement). The actuator consists in using a surface dielectric barrier discharge with a thin dielectric made by a combination of two polymer materials. The first part of this work is dedicated to the experimental study of the flow induced by the actuator in quiescent air according to the regime of the discharge. An empirical law is proposed in order to determine the velocity of the ionic wind as a function of the high voltage and the frequency of the actuator. From this law the main properties of the wall jet induced by the discharge are predicted. In the second part of the study the actuator is used for wind tunnel experiments for three configurations of increasing complexity: laminar boundary layer (flat plane), separated turbulent boundary layer (wing profile) and 3D separated boundary layer (Ahmed body with rear window tilted at 25°). Significant results are obtained for Reynolds numbers up to 1.7.106 (35 m/s).
