Compression et inférence des opérateurs intégraux : applications à la restauration d’images dégradées par des flous variables / Approximation and estimation of integral operators : applications to the restoration of images degraded by spatially varying blursEscande, Paul 26 September 2016 (has links)
Le problème de restauration d'images dégradées par des flous variables connaît un attrait croissant et touche plusieurs domaines tels que l'astronomie, la vision par ordinateur et la microscopie à feuille de lumière où les images sont de taille un milliard de pixels. Les flous variables peuvent être modélisés par des opérateurs intégraux qui associent à une image nette u, une image floue Hu. Une fois discrétisé pour être appliqué sur des images de N pixels, l'opérateur H peut être vu comme une matrice de taille N x N. Pour les applications visées, la matrice est stockée en mémoire avec un exaoctet. On voit apparaître ici les difficultés liées à ce problème de restauration des images qui sont i) le stockage de ce grand volume de données, ii) les coûts de calculs prohibitifs des produits matrice-vecteur. Ce problème souffre du fléau de la dimension. D'autre part, dans beaucoup d'applications, l'opérateur de flou n'est pas ou que partialement connu. Il y a donc deux problèmes complémentaires mais étroitement liés qui sont l'approximation et l'estimation des opérateurs de flou. Cette thèse a consisté à développer des nouveaux modèles et méthodes numériques permettant de traiter ces problèmes. / The restoration of images degraded by spatially varying blurs is a problem of increasing importance. It is encountered in many applications such as astronomy, computer vision and fluorescence microscopy where images can be of size one billion pixels. Variable blurs can be modelled by linear integral operators H that map a sharp image u to its blurred version Hu. After discretization of the image on a grid of N pixels, H can be viewed as a matrix of size N x N. For targeted applications, matrices is stored with using exabytes on the memory. This simple observation illustrates the difficulties associated to this problem: i) the storage of a huge amount of data, ii) the prohibitive computation costs of matrix-vector products. This problems suffers from the challenging curse of dimensionality. In addition, in many applications, the operator is usually unknown or only partially known. There are therefore two different problems, the approximation and the estimation of blurring operators. They are intricate and have to be addressed with a global overview. Most of the work of this thesis is dedicated to the development of new models and computational methods to address those issues.

Protection of petroleum resources in Africa : a comparative analysis of oil and gas laws of selected African StatesMailula, Douglas Tlogane 08 July 2014 (has links)
The resource curse is a defining feature of the African content. Despite vast resource wealth, Africa remains the poorest and most underdeveloped continent in the world. The aim of this study is to conduct a comparative analysis of the primary laws regulating of oil and gas exploration and product activities in Angola, Nigeria and South Africa in order to determine their effectiveness in protecting the continent's depleting petroleum resources. Different regulatory models apply to Angola, following the Norwegian carried-interest model, Nigeria, where a British discretionary model has been retained, an a South africa, where a unique model has been developed. The comparison is conducted by analysing and comparing these different regulatory systems in terms of legal frameworks; the legal nature of the regulatory systems; ownership of the oil and gas resources; legal nature of licenses; organisational or institutional structures; fiscal systems; local communities benefits from these proceeds of oil and gas resources; local content; state/government participation arrangements; and environmental challenges. The study evaluates the effectiveness of these regimes by examining the extent to which they recognise and enforce state ownership of he oil and gas resourcs in situ; recognise and enforce the doctrine of Permanent Sovereignty over Natural Resources (PSNR); protect the environment; how they provide for institutional capacities for the management of resources; and the protection of local communities from exploitation and abuse by recognising their rights to benefit from revenues derived from these resources. An overall assessment of the three systems reveals that there is no ideal model for oil and gas regulation in Africa. The Norwegian model might well be considered an ideal model if it was applied with care and correctly in Angola. The study hopes to gain practical importance for the proper regulationof the oil and gas industries' upstream activities in Africa and assist governments of the selected jurisdictions in their policy revisions, as some recommendations are made. / Public, Constitutional and International Law / LL.

Nine Lives: A History of Cat Women, Subversive Femininity, and Transgressive Archetypes in FilmBarnett, Katrina 08 1900 (has links)
The intention of this thesis is to identify and analyze the cat woman archetype as a contemporary extension of the transgressive witch archetype, which rampantly appears over the course of cinema history, working as a signifier of a patriarchal society's fear of autonomous and subversive women. The character of Catwoman is the ultimate representation for this archetype on grounds of her visibility, longevity, and ability to return again and again. More importantly, Catwoman and her sisterhood of cat women work against male creators as a means of female empowerment through trickery. Within this thesis, key films of varying genres are drawn from throughout cinema history and analyzed in order to demonstrate the intertextual network of characters that make up the cat woman archetype, and the importance of the Catwoman character in her many forms.

“Accumulation by Dispossession” by the Global Extractive Industry: The Case of CanadaKinuthia, Wanyee 13 November 2013 (has links)
This thesis draws on David Harvey’s concept of “accumulation by dispossession” and an international political economy (IPE) approach centred on the institutional arrangements and power structures that privilege certain actors and values, in order to critique current capitalist practices of primitive accumulation by the global corporate extractive industry. The thesis examines how accumulation by dispossession by the global extractive industry is facilitated by the “free entry” or “free mining” principle. It does so by focusing on Canada as a leader in the global extractive industry and the spread of this country’s mining laws to other countries – in other words, the transnationalisation of norms in the global extractive industry – so as to maintain a consistent and familiar operating environment for Canadian extractive companies. The transnationalisation of norms is further promoted by key international institutions such as the World Bank, which is also the world’s largest development lender and also plays a key role in shaping the regulations that govern natural resource extraction. The thesis briefly investigates some Canadian examples of resource extraction projects, in order to demonstrate the weaknesses of Canadian mining laws, particularly the lack of protection of landowners’ rights under the free entry system and the subsequent need for “free, prior and informed consent” (FPIC). The thesis also considers some of the challenges to the adoption and implementation of the right to FPIC. These challenges include embedded institutional structures like the free entry mining system, international political economy (IPE) as shaped by international institutions and powerful corporations, as well as concerns regarding ‘local’ power structures or the legitimacy of representatives of communities affected by extractive projects. The thesis concludes that in order for Canada to be truly recognized as a leader in the global extractive industry, it must establish legal norms domestically to ensure that Canadian mining companies and residents can be held accountable when there is evidence of environmental and/or human rights violations associated with the activities of Canadian mining companies abroad. The thesis also concludes that Canada needs to address underlying structural issues such as the free entry mining system and implement FPIC, in order to curb “accumulation by dispossession” by the extractive industry, both domestically and abroad.
