This diploma thesis deals with the historical development of the Israeli nuclear program and examines motives which led either to the decision to acquire nuclear weapons or to further develop Israeli nuclear arsenal. Indentified motives are compared with the theory by Scott Sagan who proposed three 'models in search of the bomb'. Security Model sees the effect of nuclear weapons on state security as the motivation, the Domestic Politics Model considers nuclear weapons to be a tool for gaining political profit and the Norms Model emphasizes their symbolic value. My proposition is that other than abovementioned motives, or more motives from different models might be found. Such a result would pose a challenge to Sagan's theory, and could be used a basis for further research. To define independent variables, which are the motives in my case, the method of process tracing is used. I identify critical moments which led to changes in the direction of the program, and define motives on their basis. In the thesis, I further deal with the policy of strategic ambiguity, which consists in complete non-acknowledgement of Israel's nuclear status and enabled Israel to reduce negative effects of the region's nuclearization.

The Evening Service settings of great British composers like Charles Stanford, A. Herbert Brewer, Charles Wood and Herbert Howells are well known and performed often throughout the world. However, little is known about the body of settings created by American composers. There are currently approximately 75 American composers dating from 1890 to the present, with Evening Service settings in print. Joel Martinson, based in Dallas, Texas, is an American composer, church musician, concert organist, and presenter. Although Martinson has composed four Evening Service settings (Evening Service for the St. Mark's School 1996, Evening Service for the Incarnation 2000, Evening Service for Church of the Nativity 2002, and Evening Service for the Transfiguration 2015), these works are not widely known outside of Dallas and small Anglican circles, nor is the value of his contributions to Anglican Evensong repertoire recognized. The purpose of this study is to demonstrate that Martinson's four settings make a valuable American contribution to Anglican repertoire through his neo-classical style and creative counterpoint. The four settings are modern and challenging but remain approachable for both choir and audience.

The purpose of this research is to develop and architect a preliminary multidisciplinary design optimization (MDO) tool that creates multiple types of generalized rocket fairing models. These models are sized relative to input geometric models and are analyzed and optimized, taking into account the primary objectives, namely the structural, thermal, and aerodynamic aspects of standard rocket flights. A variety of standard nose cone shapes is used as optimization proof of concept examples, being sized and compared to determine optimal choices based on the input specifications, such as the rocket body geometry and the specified trajectory paths. Any input models can be optimized to their respective best nose cone style or optimized to each of the cone styles individually, depending on the desired constraints. Two proof of concept example rocket model studies are included with varying sizes and speeds. Both have been optimized using the processes described to provide delineative instances into how results are improved and time saved. This is done by optimizing shape and thickness of the fairings while ascertaining if the remaining length downstream on the designated rocket model remains within specified stress and temperature ranges. The first optimized example exhibits a region of high stress downstream on the rocket body model that champions how these tools can be used to catch weaknesses and improve the overall integrity of a rocket design. The second example demonstrates how more established rocket designs can decrease their weight and drag through optimization of the fairing design.

Ayant recours aux théories de la «surconscience linguistique», du «choc des langues» et des «zones de contact» telles que développées par Lise Gauvin, Sherry Simon et Catherine Leclerc, ce mémoire a pour objectif de développer une littérature montréalaise activée par la langue et les langues dans un contexte contemporain. S'inspirant des débats entourant la littérature anglo-québécoise, et la place accordée à l'imaginaire anglo-montréalais et à ses représentants dans l'histoire, deux romans sont analysés du point de vue des langues : La logeuse d'Eric Dupont et Heroine de Gail Scott. À la lumière d'une interdiction formulée par Gilles Marcotte dans « Neil Bissoondath disait… », célèbre brûlot qui prohibe l’analyse conjointe des littératures de langue française et anglaise, l'approche adoptée dans ce mémoire vise par l'intermédiaire des romans à dépasser les propos de Marcotte afin de créer une spécificité montréalaise orientée par des préoccupations linguistiques. Ce mémoire démontre que les propos de Gilles Marcotte sont intenables dans le contexte actuel où les langues ne sont plus une source de division, mais bien un prétexte à joindre dans un propos qui les englobe et les dépasse les corpus de langue anglaise et française dans le contexte montréalais. La logeuse et Heroine témoignent d'un imaginaire et de préoccupations linguistiques comparables et de ce fait, permettent de définir les contours d'une littérature montréalaise activée par les langues. Enfin, ce mémoire se questionne sur l'équation entre langue et culture, mais également entre littérature et culture afin qu'une langue montréalaise, à l'instar d'une littérature montréalaise, prenne forme. / Refering to the theories of Lise Gauvin, Sherry Simon and Catherine Leclerc on «linguistic superconsciousness» (surconscience linguistique), «impact of languages» (choc des langues), and « contact zones» (zones de contact), this thesis produces a Montreal literature which is based on languages, French and English, in a contemporary context. Motivated by the debates around anglo-quebec literature and anglo-quebec writers, this thesis analyses two novels from the points of view of languages : Eric Dupont's La logeuse and Gail Scott's Heroine. The main objective of this study is to show that the concept developed by Gilles Marcotte in « Neil Bissoondath disait » which forbids comparisons between French an English texts, is obsolescent following the reading of the two novels. This thesis shows that in the context of Montreal, languages can create a specificity when they are not anymore a pretext to division, but the sign of a reconciliation.
