La fuite d’information d’une réalisation quantique de primitives 
cryptographiques classiques

We are interested in classical cryptographic primitive implemented by quantum states. We introduce the concepts of advantage and  -embedding. Following this, we show that for every state there exist a strict-correct state for which the difference between the leakage of both states is upper bounded. This result shows a relation between the leakage and the measure of dependency of Alice and Bob’s quantum registers. We then show that if a state exhibits one of two properties, then its leakage is lower bounded by that of a strict-correct state. This shows that the results of Salvail and al. [26] can be generalized to generic states that satisfy those conditions. Finally, we do a numerical analysis of the leakage of embedding for 1-2-OT and ROT primitives. We find a state that leaks less information than the lower bound previously found by Salvail and al. in [26].

Turbulence de surface pour des simulations de fluides basées sur un système de particules

Accurately simulating the behaviour of fluids remains a difficult problem in computer graphics, and performing these simulations at a high level of detail is particularly challenging due to the complexity of the underlying dynamics of a fluid. A recent and significant body of work targets this problem by trying to augment the apparent resolution of an underlying, lower-resolution simulation, instead of performing a more costly simulation at the full-resolution. Adaptive or multi-scale methods in this area have proven successful for simulations of smoke and liquids, but no comprehensive solution exists.  The goal of this thesis is to devise a new multi-scale detail-augmentation technique suitable for application atop existing particle-based fluid simulators. Particle simulations of fluid dynamics are a popular, heavily-used alternative to grid-based simulations due to their ability to better preserve energy, and no detail-augmentation techniques have been devised for this class of simulator. As such, our work would permit digital artists to perform more efficient lower-resolution particle simulations of a liquid, and then layer-on a detailed secondary simulation at a negligible cost.  To do so, we present a method for reconstructing the surface of a liquid, during the particle simulation, in a manner that is amenable to high-frequency detail injection due to higher-resolution surface tension effects. Our technique detects potentially under-resolved regions on the initial simulation and synthesizes turbulent dynamics with novel multi-frequency oscillators. These dynamics result in a high-frequency wave simulation that is propagated over the (reconstructed) liquid surface.  Our algorithm can be applied as a post-process, completely independent of the underlying simulation code, and so it is trivial to integrate in an existing 3D digital content creation pipeline.

SLA violation prediction : a machine learning perspective

Cloud computing reduces the maintenance costs of services and allows users to access on demand services without being involved in technical implementation details. The relationship between a cloud provider and a customer is governed with a Service Level Agreement (SLA) that is established to define the level of the service and its associated costs. SLA usually contains specific parameters and a minimum level of quality for each element of the service that is negotiated between a cloud provider and a customer.  However, one or more than one of the agreed terms in an SLA might be violated due to several issues such as occasional technical problems. Violations do happen in real world. In terms of availability, Amazon Elastic Cloud faced an outage in 2011 when it crashed and many large customers such as Reddit and Quora were down for more than one day. As SLA violation prediction benefits both user and cloud provider, in recent years, cloud researchers have started investigating models that are capable of prediction future violations. From a Machine Learning point of view, the problem of SLA violation prediction amounts to a binary classification problem.  In this thesis, we explore two Machine Learning classification models: Naive Bayes and Random Forest to predict future violations using features of a submitted task. Unlike previous works on SLA violation prediction or avoidance, our models are trained on a real world dataset which introduces new challenges. We validate our models using Google Cloud Cluster trace as the dataset.  Since SLA violations are rare events in real world 2.2 %, the classification task becomes more challenging because the classifier will always have the tendency to predict the dominant class. In order to overcome this issue, we use several re-sampling methods such as Random Over-Sampling, Under-Sampling, SMOTH, NearMiss, One-sided Selection, Neighborhood Cleaning Rule and an ensemble of them to re-balance the dataset.

Comparing of radial and tangencial geometric for cylindric panorama

Cameras generally have a field of view only large enough to capture a portion of their surroundings. The goal of immersion is to replace many of your senses with virtual ones, so that the virtual environment will feel as real as possible. Panoramic cameras are used to capture the entire 360°view, also known as panoramic images.Virtual reality makes use of these panoramic images to provide a more immersive experience  compared  to  seeing  images  on  a  2D  screen.  This  thesis,  which  is  in the field of  Computer vision, focuses on establishing a multi-camera geometry to  generate  a  cylindrical  panorama  image  and  successfully  implementing  it  with the cheapest cameras possible. The specific goal of this project is to propose the cameras geometry which will decrease artifact problems related to parallax in the panorama image. We present a new approach of cylindrical panoramic images from multiple cameras which its setup has cameras placed evenly around a circle. Instead of looking outward, which is the traditional ”radial” configuration, we propose to make the optical axes tangent to the camera circle, a ”tangential” configuration. Beside an analysis and comparison of radial and tangential geometries, we provide an experimental setup with real panoramas obtained in realistic conditions

Collectionner la performance : J'aime Montréal et Montréal m'aime de Thierry Marceau, une intégration unique

The ephemeral nature of performance makes it difficult to collect for the institutions dedicated to contemporary art and, therefore, generates a misrepresentation of this artistic practice in public collections. Indeed, the museum is reluctant to this process that it considers necessarily problematic. For its part, the Art and Architecture Integration Policy only collects works materially stable and, despite this, it encounters several difficulties. Obviously, collecting performance is simply unthinkable in this case. That is why this thesis focuses on the novel integration program of Art Actuel 2-22. J’aime Montréal et Montréal m’aime of Thierry Marceau is effectively an exception in Quebec’s measure because, once its five phases completed, this performative work will be done. This integration is considered as a case study that allows us to defend the presence of the ephemeral in public space.

Psychopathologies et marginalités : la mythologie du mal-être entourant le BDSM dans le cinéma occidental du début du 21e siècle

The formerly widespread view of BDSM as a psychological disorder is currently being abandoned by large portions of the scientific community; it has been almost completely removed from the most recent edition of the Diagnostic and Statistical Manual of Mental Disorders, and a growing number of studies point toward the psychological and social normalcy of BDSM practitioners. Yet, since the early 2000’s, from trans-european productions like Nymph()maniac (Lars von Trier, 2013) to independent Australian features like My Mistress (Stephen Lance, 2014), or mainstream american films like Fifty Shades of Grey (Sam Taylor-Johnson, 2015), the onscreen portrayal of BDSM practitioners increasingly consists of characters with troubled lives and fragile mental healths. The aim of this thesis will be to investigate the many biases that motivate this mythology of unease surrounding BDSM in film. In order to take a closer look at the gap between current research in psychology and cultural representation of BDSM we developed a case study of Nymph()maniac, which features, among a wide array of sexual proclivities, a temporary D/s relationship. With the intention of gaining access to the perspective of women-identified people from the BDSM community on the way they are represented in movies, we generated a focus group and gathered their reactions. We therefore propose an interpretative dialogue between the BDSM community, literary criticism, sociology, psychology and feminist cultural studies.

L'image de Rhodes à la Renaissance : les enjeux d'une représentation

The fifteenth and sixteenth centuries saw great breakthroughs in the arts and sciences and were traversed by extreme political and religious tensions. The Ottoman Empire, then in full expansion, advanced dangerously towards the Christian West, which was itself torn by innumerable internal conflicts. Located only a few kilometers from the Anatolian coast, the island of Rhodes represented an obstacle to the conquests of the Ottoman Porte, and was seen by the West as the last Christian stronghold in the eastern Mediterranean. Besieged in 1480 and finally taken by Suleyman the Magnificent in 1522, the island occupied an important place in the Western imagery of the time as a symbol of the struggle against the Ottoman Empire. In a context of discoveries and increasing knowledge about geography, and of questioning the space and the way to represent it, the geographical and chorographical representations of Rhodes multiplied. These images depict a Western vision of the Ottomans and the conflictual reality of power relationships between the East and the West during the Renaissance. They are studied not only as forms of artistic expression but as cultural constructions carrying the ideology and the territorial imperatives of the european societies. This dissertation, through the study of a corpus of chosen images, analyzes these representations in order to highlight their intrinsic link with the notion of power and the idea of territorial possession.

La famille et la pensée émersonienne dans le cinéma de Paul Thomas Anderson

This research focuses on the family in the films of Paul Thomas Anderson. His representation is a reflection of tensions and conflicts that are found in contemporary American family, that sociologists such as Weber, Bateson, Becker and Sombart allowed us to analyze the basis and the (dys) function. The director places the family at the center of his films, showing either the failure or the surrogate reconstitution of a family unit. While rewarding it, Anderson also shows the flaws of it. The dichotomy that arises from the contrast between family happiness and personal success, economic or social, reveals a multitude of family issues that Anderson’s cinema seems to expose by failure of the patriarchal model. Now, is the american family, in Anderson’s movies, suffered economic aspirations and individual success of men, thereby causing it to malfunction, or is it rather the main reason that prompts nonconformist to seek solutions in alternative communities? Our hypothesis is that moral perfectionism and his injunction of non-compliance, which supports individual project, conflicts with the pursuit of family happiness. This oscillation between the personal and the collective recall the ideas developed by Ralph Waldo Emerson on the self-reliance and on the construction of common trust. We will look more specifically at andersoniens characters that are part of a family or community in order to lay the foundations for an emancipatory transformation.

Ici rien n'est silencieux : reconfigurations de l'audible sous le régime esthétique des arts

Written under the supervision of Michèle Garneau, this master’s thesis discusses the integration of noise in music, from the Romantic revolution up to the advent of post-punk, seen through the notion of "aesthetic regime" theorised by Jacques Rancière : a particular mode of experience according to which the Western thought would identify, since about two centuries, what makes or doesn’t make art. In opposition with the Aristotelian poetics and its solid hierarchies, which shape the dominant taste from the Ancient Greece up to the Enlightenment, the new paradigm is said to be based on the reconciliation of the contraries : the noble and the vulgar, the active and the passive, the conscious and the unconscious, etc. This process of indifferentiation is at the core of our work. Only, where Rancière favours literature, cinema and the fine arts, we propose to concentrate on music : on the practices and the discourses that, since the Romantic era, blur his definitions and make it slip into noise. A project that will take us from Novalis’ "everything speaks" to John Cage’s "everything we do is music", from Victor Hugo’s "harmony of the contraries" to Richard Meltzer’s rock "totality", from Gustave Courbet’s "negation of the ideal" to no wave’s radical refusal

Divergences et avant-garde : l’architecture moderne dans les expositions universelles, 1925-1937

The World’s Fairs have generally been perceived as motors for modernity. These gigantic events, aside from presenting the world’s most recent technologies and industrial developments have always been playgrounds for architects, making architecture the key component. This thesis studies the links between the world’s fairs and the emergence of modern architecture in the first half of the twentieth century. To do so, it studies the Parisian fairs of 1925 and 1937. Carried by architects such as Le Corbusier, Konstantin Melnikov or Josep Lluis Sert, these fairs reveal divergent architecture, both artistic and political. Throughout these fairs, the official stances — those of the governments and the organizers — have continually been challenged. In this thesis, it is this idea of confrontation that we put forward as to reveal how these divergences from the official stances have enabled the emergence of modern architecture. These divergences are artistic, political, and ideological. This thesis is inspired by the ways and means of architectural historians Kenneth Frampton, Michel Ragon, and Jean-Louis Cohen. We borrow their ways of integrating architectural elements in a wider and well-defined sociohistorcial and political context.

L’ocularisation vidéoludique : une typologie des points de vue à l’intérieur des phases interactives dans les jeux vidéo tridimensionnels

An overview of the theories on the point of view and on the ocularization in cinema shows that the researches were well conducted in this field of study. However, the same report cannot be done in video game. The notion of point of view has not been analyzed and theorized with the same exhaustiveness and deepening. Many gaps are still visible and the purpose of this thesis is to target some of them and to fill them. This research thus examines the points of view in video games and more specifically, those that are found within the interactive phases (cutscenes are for example excluded) in three-dimensional games. A typology of ocularization, that is to say a new categorization of the different types of visualization, is presented, analyzed and exemplified throughout this thesis. This one goes into deeper details than those already developed in the past, because it takes into account a greater variety of characteristics: anchor, positioning, mobility and control available to the player. Also, it details the impact of the various points of view on the user’s experience by focusing on two axes: aesthetic and functionality. Ultimately, this thesis allows establishing a more elaborate theory on ocularization in video game studies.

De l’espace de jeu au temps du joueur : une épistémologie engagée du jeu en général, et du jeu vidéo en particulier

The game constitution as an object of science and the institutionalization of the video game oust the essence, and therefore the meaning of the subject they intend to define. The game itself and its playful representation took precedence over the experience of the player. The game phenomenon remains a subjective object: when defining the object, this subjective dimension and its experiential variables are subjectively minimized, especially time and movement. Based on multidisciplinary theories such as phenomenology, semiotics and cognitive linguistics, this paper seeks to rehabilitate the time, the player and the experience of playing. The first chapter examines the ambiguity of the word game, which refers to both the object and the game playing activity, and questions the primacy of game over play in the game studies. The second chapter questions the dualistic conception of game, as conveyed by the magic circle model, which opposes gaming to reality. Chapter three provides the conceptual metaphor of time suspended in space to explain firstly, the structuring role of space in the cognitive process, and also the spatial outbid of the video game discourse. Finally, it is about holding and maintaining the dynamic balance between the gaming structure and the experience of playing, and stress the importance of space-time unity.

Au-delà de l'hégémonie humaine : examen de deux œuvres équestres de Rosa Bonheur : Le marché aux chevaux (1853-1855) et Rocky Bear and Chief Red Shirt (1889)

Through her depictions of the human/horse relationship, the animal painter Rosa Bonheur has shown herself to be a pioneer in the advent of animal ethics. In life she enjoyed an enviable popularity and posthumously her work has continued to attract attention with most studies focussing on her biography, reading her famous The Horse Fair (1853-1855) through the prism of her sexuality. Such approaches are too limited and fail to do justice to Bonheur’s artistic philosophy, overwriting the importance of the horse, a key subject in many of her works. This dissertation takes an alternative approach, one more in keeping with the artist’s animal ethics. Inspired by recent research in animal studies, particularly research informed by deconstruction, the thesis demonstrates how Bonheur’s representation of interspecies relations raises key ethical questions. In this context, Rocky Bear and Chief Red Shirt (1889), a painting which has been unduly neglected in existing art historical scholarship, forms a vital work, one which is considered alongside the celebrated The Horse Fair as a means to understand Bonheur’s equine ethics. Through an analysis of these paintings in particular, the thesis invites a reassessment of Bonheur’s art as an expression of her commitment to the ethical treatment of horses and also seeks to make a significant contribution to understanding the role practices of representation more generally, including art, can play in the transformation of our perception of non-human animals.

Du cinéma militant au cinéma résistant : le regard décalé d'Elia Suleiman

This work, a project originally motivated by a personal desire of making « political films », attempts to redefine certain links between cinema and resistance by leaning on the resistant approach of Elia Suleiman. If the engagement in cinema was mostly associated with the ideological approach of the militant cinema, that consists of using cinema as an « instrument » for revolutionary purposes (to oppose a government, a colonizer or any other particular power), I propose in this work to demonstrate that the resistance of Suleiman consists in questioning all kinds of dominant narratives and every possible form of power, including those that concern the medium of cinema itself. Therefore, Suleiman presents a resistance with the cinema and not in the cinema: It is a mediation of resistance rather than a representation of revolutions. Following the same theoretical line as Gilles Deleuze, Michel Foucault, Jacques Rancière and Edward Saïd, I put forward the hypothesis that cinematographic resistance must be active, in other words able to invent new ways of seeing and listening (being and thinking) that can be distinguished from the repressive logic of power. By questioning the ideological, narrative and didactic discourse of the militant cinema, I identify three possible fields of resistance (political, aesthetic, and ethic) that will ultimately be verified and completed by my work of creation.

Concevoir l’international : le Comité national d’études sociales et politiques d’Albert Kahn, 1916-1931

During the heat of the Great War, Albert Kahn, banker and philanthropist, founded the Comité national d’études sociales et politiques (CNESP). Bringing together members of the French elite, the CNESP held meetings every week until 1931, to hold intellectual discussions about current affairs. Even though the members were exclusively French, the committee invited a considerable number of international speakers. This thesis, whose fields of research are linked to those of intellectual history and international history, places emphasis on this committee’s interest in international topics and studies its conceptualization of internationalism during the interwar period.   This survey of the CNESP’s meetings reveals that the committee had a vision of internationalism that was expressed on two different levels. First, the committee understood the international as an objective structure: the international system had to be organized around principles of law and international problems had to be resolved by the objective methods of science. Second, study of the subjective considerations behind those pretentions of objectivity reveals that the conceptualisation of internationalism was influenced by a strong belief in the universalism of French values. This conceptualisation of internationalism therefore implies dynamics of exclusion that are expressed more particularly through a metaphoric discourse linked to the family.
