This thesis serves to provide insight into the interpretation and performance of Rebecca Clarke’s Sonata for Viola and Piano (1919). To provide context to the analysis and interpretation, the life and work of Rebecca Clarke (1886-1979) is described. The viola sonata is analysed in terms of harmony, colours and technical elements for the purpose of aiding the interpretation and performance. The sonata is also cross referenced with other works by the same composer, to further pinpoint the stylistic elements and their importance for the result. From the analysis it is concluded that the common elements in Clarke’s music and in the sonata in particular, include modality, harmonic ambiguity, polytonality and a range of instrumental techniques. The meticulous notation and the overall instrumental ergonomics of the piece shows both that Clarke had a clear vision for her music, and that she knew the nature of both the viola and the piano well. In conclusion, I argue that in order to present a captivating performance of the piece, great care must be taken to the distinction and sensitivity of these elements in particular. / <p>R.

Este trabalho apresenta um conjunto de métodos para a proteção e o monitoramento de transformadores de potência baseado em sistemas inteligentes e na aplicação das transformadas de Clarke e Wavelet. A abordagem inteligente utilizada permite analisar a condição operativa dos transformadores de potência e detectar a ocorrência de defeito interno, distinguindo-a de outras situações de operação, como, a energização, a energização solidária, a saturação dos transformadores de corrente e a sobreexcitação. As tomadas de decisão das técnicas desenvolvidas são realizadas pela lógica fuzzy após o pré-processamento dos sinais de entrada por meio de diversos métodos, os quais variam de acordo com o algoritmo que esta sendo executado. Os algoritmos propostos foram testados por meio de simulações realizadas através do software Alternative Transients Program (ATP). É importante salientar que nas simulações do ATP foram modelados diversos equipamentos que constituem o sistema elétrico de potência, incluindo um gerador síncrono com regulação de velocidade, linhas de transmissão com variação em frequência, transformadores de potência com suas respectivas curvas de saturação, transformadores de potencial e de corrente. Estas modelagens tiveram por objetivo gerar dados das distintas situações de operação para a verificação e análise da metodologia proposta. Os resultados da pesquisa mostram a aplicabilidade dos algoritmos propostos na proteção e no monitoramento dos transformadores de potência, mesmo nas condições mais adversas, como na ocorrência da saturação dos transformadores de corrente, uma vez que os sinais de entrada distorcidos pela saturação são corrigidos por uma rede neural artificial. Os resultados apresentados comparam as respostas obtidas pelas técnicas propostas em relação às saídas de um relé comercial, habilitado à proteção diferencial percentual. / This work presents a set of methods for protecting and monitoring power transformers based on intelligent systems and the application of Clarke and Wavelet transforms. The intelligent approach allowed us to analyze the operating condition of power transformers and it discriminates between an internal fault and different operating conditions, as energization, sympathetic inrush, saturation of current transformers and overexcitation. Decision making is performed by fuzzy logic after the preprocessing of the input signals through various methods, varying according to which algorithm is running. It is important to point out that in the simulations using ATP many different power system equipment had been modeled, including a synchronous generator with speed regulation, transmission lines with variation in frequency, power transformers with their saturation curves, potential transformers and current transformers. The objective of these tests was to generate data for distinct situations for the verification and the analysis of the proposed methodologies. The results of the research show the applicability of the algorithms considered in protection and monitoring of power transformers, even in adverse conditions, such as saturation of current transformers, since the input signals are distorted by CT saturation corrected by artificial neural network. The results are compared to the ones presented by a commercial percentage differential relay.

The aim of this thesis is to explore the elements of power-knowledge in two SF novels written amid the Space Race during the Cold War era. While the dominant interest of both Stanislaw Lem’s Solaris and Arthur C. Clarke’s Rendezvous with Rama generally revolves around the implications of human interactions with an alien presence, my focus is primarily on the power structures that propel those interactions: questioning the intentions of scientific pursuits and analyzing the effects of Foucauldian power relations on the human individual. I do this by applying Foucault’s theories of the duality of the subject and his work on biopolitics. What is gleaned is not only a study of the interests of power, but an emphasis on the intersectional restrictions of power and cognition. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection

The purpose of this study is to examine three works for the unusual combination of violin and voice. Chamber music for violin and keyboard and violin and other instruments has been extant since the Baroque period. However, three English composers found a unique chamber grouping in the first decades of the twentieth century: Gustav Holst (1874-1934), Rebecca Clarke (1886-1979), and Ralph Vaughan Williams (1872-1958) each wrote works for violin and voice. Holst's Four Songs for Voice and Violin, Op. 35 (1917), Vaughan Williams' Along the Field, Eight Housman Songs for Voice and Violin (1927, revised 1954), and Clarke's Three Old English Songs (1924) each utilize the combination of violin and voice. The violin in each is not relegated to accompaniment but is instead a true partner. This study will investigate these works. A history of each composition will be chronicled. An analytical discussion of formal organization and significant style features will include consideration of the musical structure, harmonic language, and the use of text in select movements of each work. Finally, performance suggestions pertaining to technical and artistic issues offer specific recommendations as an aid in performance preparation. In order to provide historical and musical context, a brief overview of Late Romantic and early Twentieth-Century chamber music with strings and voice will be given. This overview will help to illuminate the uniqueness of the pairing of violin and voice. Discovery of the works discussed here makes possible an expanded repertoire of good music for both violinists and vocalists. It is also hoped that through the performance of these works a spark might be set with composers to create more pieces for this most intimate of duos.

Le travail présenté dans ce mémoire est divisé en deux parties. La première partie est consacrée aux calculs des fonctions d'appui de la Jacobienne généralisée de Clarke et de son enveloppe plénière, associées à une fonction localement lipschtizienne à valeurs vectorielles. Clarke avait établi en 1975 que la fonction d'appui du sous-différentiel généralisé était une dérivée directionnelle généralisée. Il est donc satisfaisant de constater que la fonction d'appui de la Jacobienne généralisée est une sorte de "divergence directionnelle généralisée". Dans la seconde partie, nous présentons un certain nombre d'applications de techniques issues de l'Analyse non lisse à la résolution d'équations de Hamilton-Jacobi du premier ordre. Ainsi nous utilisons la dualité convexe et le calcul sous-différentiel pour prouver que les formules dites de Hopf-Lax définissent des solutions explicites des équations de Hamilton-Jacobi associées (avec données initiales semicontinues inférieurement). Nous n'utilisons ni le fameux principe de comparaison de la théorie des solutions de viscosité ni régularisation. Nous traitons successivement le cas de la dimension finie et de la dimension infinie. Ces résultats nous permettent de trouver des estimations des solutions d'équations dont l'hamiltonien est la différence de deux fonctions convexes. Enfin, nous nous attachons à l'étude des solutions sci dans des espaces de Banach dits ``lisses''. Le théorème de la valeur moyenne de Clarke et Ledyaev nous permet de montrer un résultat d'``enveloppe'' : nous construisons une solution sci pour une équation dont l'hamiltonien est le supremum d'une famille d'hamiltoniens. Nous appliquons enfin les mêmes techniques pour prouver l'existence d'une solution sci minimale sous des hypothèses plus faibles que celles que l'on recontre généralement dans la littérature.

Semi-infinite programming problems is a class of optimization problems in finite dimensional variables which are subject to infinitely many inequality constraints. If the infinite index of inequality constraints depends on the decision variable, then the problem is called generalized semi-infinite programming problem (GSIP). If the infinite index set is fixed, then the problem is called standard semi-infinite programming problem (SIP). In this thesis, convergence of a semismooth Newton method for generalized semi-infinite programming problems with convex lower level problems is investigated. In this method, using nonlinear complementarity problem functions the upper and lower level Karush-Kuhn-Tucker conditions of the optimization problem are reformulated as a semismooth system of equations. A possible violation of strict complementary slackness causes nonsmoothness. In this study, we show that the standard regularity condition for convergence of the semismooth Newton method is satisfied under natural assumptions for semi-infinite programs. In fact, under the Reduction Ansatz in the lower level problem and strong stability in the reduced upper level problem this regularity condition is satisfied. In particular, we do not have to assume strict complementary slackness in the upper level. Furthermore, in this thesis we neither assume strict complementary slackness in the upper nor in the lower level. In the case of violation of strict complementary slackness in the lower level, the auxiliary functions of the locally reduced problem are not necessarily twice continuously differentiable. But still, we can show that a standard regularity condition for quadratic convergence of the semismooth Newton method holds under a natural assumption for semi-infinite programs. Numerical examples from, among others, design centering and robust optimization illustrate the performance of the method.

This thesis examines the use of the pastoral form in recent Canadian literature. As the pastoral constitutes a literary site where a concern for landscape converges with a search for community, it has been employed as a myth in nationalist discourses whose functioning depend heavily on symbolized landscapes and idealized social types. The philosophical basis of the pastoral is the classical opposition between nature and culture. For this reason, its representations are often coded as 'natural'. To this extent, the pastoral participates in a hegemonic myth-making system, constituting a limited semiotic field in which certain representations are privileged while others are negated. Following Marx and Barthes, the thesis contends that an attack the nature/culture opposition is essential to undermining the hegemony of the myth-making process. In the context of nationalism, a pastoral can articulate a critique of dominant a 'naturalized' representations when it questions its own use of the nature/culture opposition.

On 5 June 1967, the Israeli Air Force launched a surprise attack against the Egyptian Air Force and started what was to be known as the Six Day War. The Six Day War is a good example of when a small nation manages to singlehandedly defeat a superior adversary. The purpose of this paper is to analyze the success of the Israeli Air Force and their contribution to the victory. The use of air power in the Six Day War will be analyzed, using John Warden’s Five Ring Model and Shaun Clarke’s theories about risk-based coercion and SPOT-bombing. Research findings indicate that Shaun Clarke’s theories about coercion may to some extent explain the success of the Israeli Air Force. Attacking the armed forces created the threat of further violence against more valuable and vulnerable targets causing the Arabic leaders to choose peaceful solutions instead of continued fighting. Furthermore, the SPOT-bombing analyzes show that the psychological effect that the Israeli Air Force had on their adversary played a significant role in the campaign against Egypt. However, Warden’s model could not explain the reasons behind the outcome of the war.
