This thesis is an examination of sound and lived space in Janet Cardiff's audio walks, Missing Voice, and Conspiracy Theory. Its aim is to contextualize Cardiff's project in terms of how it reverses the logic of the conventional museum audio guide; taking the user on an unexpected tour of the back spaces, and by providing an audio track of soundscapes which are not about the art exhibition but rather point to the social relations constituted in each audio walk environment. Paradoxically, it is the non-synchronous elements of Cardiff's audio walks that point to the embedded nature of expectations produced by body technique. It is through the disjunction of the experiential moment between sensorial input and our awareness of it (an incongruent relationship between what is expected and what is experienced) that, Gilles Deleuze's concept of the pre-individual is actualized for the lived body. The actualized pre-individual lies at the core of an analysis, of how Cardiff's audio walk transgresses the limits of a single art work and reopens living as an emergence for the interconnectedness of the actual-virtual.

Si l'on peut observer depuis une vingtaine d'années un nombre important d'allusions à la notion de jeu, non seulement dans les thématiques et les procédés de la pratique artistique, mais également dans les propositions théoriques, on peut se demander à quel titre l'art actuel renouvelle le rapprochement entre l'art et le jeu. Maintes fois discutée durant la période moderne, que ce soit dans le champ de l'art, de la philosophie, de la psychanalyse ou de l'anthropologie, la relation entre l'art et le jeu s'inscrit actuellement dans un contexte idéologique et artistique tout autre. L'objectif de ce mémoire est de réévaluer la nature de ce rapport et de préciser le rôle de la notion de jeu dans l'art actuel. Malgré le nombre de plus en plus important de références au concept de jeu dans les pratiques artistiques, il s'agit ici d'une première étude approfondie sur le sujet. Dans un premier temps, le concept moderne de jeu se trouvera défini dans les domaines de l'esthétique et de l'anthropologie. À partir des propositions de Friedrich Schiller, Johan Huizinga et Hans-Georg Gadamer, nous démontrerons que la conception moderne du jeu est associée d'emblée à la représentation, et que celle-ci est soumise à des visées essentialistes. Dans un deuxième temps, en nous appuyant sur les théories de Jean-François Lyotard et de Jacques Derrida, le jeu sera analysé en regard des bouleversements qui accompagnent la postmodernité. Il sera envisagé comme un des concept-clé de la critique de la pensé moderne, permettant de figurer d'autres moyens d'appréhension de la réalité. Enfin, l'analyse des oeuvres de Pierrick Sorin et de Janet Cardiff, permettra de montrer que le concept postmoderne de jeu dans l'art actuel repense nos façons de configurer la réalité et notre rapport au monde. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Jeu, Art contemporain, Art et réalité, Janet Cardiff, Pierrick Sorin.

This research aims to provide an accurate and more conceptually advanced view of football violence as practiced by Cardiff City fans both past and present, than the accepted views of football already available at an academic level. Expanding on work carried out at dissertation level, the research will attempt to provide a new model of football violence, and this will be constructed through the use of a variety of research methods to better understand football hooliganism as a socio-cultural phenomenon existing within the general field of football. Football as a field of activity will be discussed, as will the fact that whilst being a field of socio-cultural activity, professional football also has developed as a distinct market. The work aims to show why certain Cardiff City F.C. fans are not content to just watch their team participate, but who through a small leap of imagination cast themselves in the role of direct participant representing the team in the contest that is football hooliganism. Also to be discussed is why certain fans (usually at a formative age) would see those with a hooligan identity at Cardiff City F.C. as best representing their interests within the field, and who then go on to adopt a hooligan identity. The interests of Cardiff City fans within the field are explored, as are the specific set of social relations that have emerged. The emergence of the casuals as a socio-cultural category is examined as is media representations of them and in a reflexive manner the role of the police within the field is also examined. Finally the research aims to show how a group such as the Soul Crew, has by a combination of continued presence and growth within the field, gone on to become one of the dominant forces within the activity.

Gneiss domes are structural features associated with orogens worldwide. This study provides a structural analysis of the domes of the Harvey Cardiff Domain, associated with the Grenville Orogeny. Structural data and oriented samples were collected during field work in the summer of 2012. These were used in combination with published and unpublished foliation and lineation data to analyze structural patterns and determine a mechanism of formation for the domes. The end member scenarios for dome formation were taken from the gneiss dome classification scheme devised by Yin (2004). Most of these mechanisms were eliminated based on a lack of necessary large scale geologic features in the region of the study area. An analysis of the foliation pattern of the Cheddar and Cardiff domes was most consistent with formation by diapirism. However, the foliation patterns of the domes differ from the expected diapiric pattern, and seems to represent a non-horizontal slice through a diapir, cutting through a diapir neck in the north and a diapir hat in the south. This pattern can also be explained by rotation of diapiric foliation due to strain induced by the main orogenic event. This hypothesis was tested using COMSOL, a finite elastic strain model, and found to be realistic. With the methods used in this study it is not possible to tell whether this rotation occurred after or during dome emplacement.

The design of power amplifiers within a circuit simulator requires a good non-linear model that accurately predicts the electormagnetic behaviour of the power transistor. In recent years, a certain class of large signal frequency-dependent black-box behavioural modeling techniques known as Poly-Harmonic Distortion (PHD) models has been devised to mimic the non-linear unmatched RF transistor. These models promise a good prediction of the device behaviour under multi-harmonic periodic continuous wave inputs. This thesis describes the capabilities of the PHD modeling framework and the theoretical type of behaviour that it is capable of predicting. Specifically, the PHD framework cannot necessarily predict the response of a broadband aperiodic signal. This analysis will be performed by deriving the PHD modeling framework as a simplification of the Volterra series kernel functions under the assumption that the power transistor is operating under continuous periodic multi-harmonic voltage and current signals in a stable circuit. A PHD model will be seen as a set of describing functions that predict the response of the Device Under Test (DUT) for any given non-linear periodic continuous-wave inputs that have a specific fundamental frequency. Two popular implementations of PHD models that can be found in the literature are the X-parameter and Cardiff models. Each model formulates the describing functions of the general PHD model differently. The mathematical formulation of the X-parameter and Cardiff models will be discussed in order to provide a theoretical ground for comparing their robustness. The X-parameter model will be seen as the first-order Taylor series approximation of the PHD model describing functions around a Large Signal Operating Point (LSOP) of the device under test. The Cardiff large-signal model uses Fourier series coefficient functions that vary with the magnitude of the large signal(s) as the PHD model describing functions. This thesis will provide a breakdown of the measurement procedure required for the extraction of these models, the challenges involved in the measurement, as well as the mathematical extraction of the model coe cients from measurement data. As each of these models contain have extended versions that enhance the predictive capability of the model under stronger nonlinear modes of operation, a comparison is used to represent the cost of increasing model accuracy as a function of the increasing model complexity for each model. The order of complexity of each model can manifest itself in terms of the mathematical formulation, the number of parameters required and the measurement time that is required to extract each model for a given DUT. This comparison will fairly assess the relative strengths and weaknesses of each model.
