After examining Harmony Korine's feature films, shorts, art installations, music videos, paintings, and novel, a clear pattern of stereotyping and misappropriating African American aesthetics emerges. This thesis addresses the mass appropriation of hip-hop aesthetics by whites, and Korine's complicity in this cultural phenomenon. Additionally, it explores the notion of hipster racism, Carmen Van Kerckhove’s term for respected artists who feel enlightened enough to stereotype in an ironic or comedic manner. Looking closely at cultural appropriation in Spring Breakers, this thesis considers hipster racism and the notion of modern-day minstrelsy. / text

The UK is facing two major challenges in the development of its electricity network. First, two thirds of the existing power stations are expected to close by 2030. Second, is the requirement to reduce its CO2 emissions by 80% by 2050. Both of these challenges are significant in their own right. The fact that they are occurring at the same time, generates a significant amount of threats to the existing power system, but also provides many new opportunities. In order to meet both these challenges, significant amounts of offshore wind generation has been installed in the UK. For the wind generation with the longest connections to land, Voltage Source Converter (VSC) based High Voltage Direct Current (HVDC) transmission has to be used. Due to the high power rating of the offshore wind farms, compared to the limited transmission capacity of the links, a large number of point-to-point connections are required. This has lead to the concept of HVDC grids being proposed, in order to reduce the amount of installed assets required. HVDC grids are a new transmission environment and the fundamental question of how they will protect themselves must be answered. Several new technologies are under consideration to provide this protection, one of which is the HVDC circuit breaker. As HVDC circuit breakers are a new technology, they must be tested in a laboratory environment to prove their operation and improve their Technology Readiness Level (TRL). This thesis is concerned with how such HVDC circuit breakers are operated, rated, and tested in a laboratory environment. A review of the existing circuit breaker technologies is given, along with descriptions of several novel circuit breakers developed in this thesis. A standardized method of rating DC circuit breaker and their associated test circuit is developed. Mathematical analysis of several circuit breakers is derived from first principles and low power prototypes are developed to validate these design concepts. A high power test circuit is then constructed and a semiconductor circuit breaker is tested. The key learning outcomes from this testing are provided.

O objetivo é adiar ou evitar a substituição de grandes quantidades de disjuntores e demais equipamentos por motivo de superação de capacidade interruptiva. O sistema em análise consiste da rede da CPFL de 138 kV, responsável pelo suprimento de energia elétrica à região metropolitana de Campinas, no interior do estado de São Paulo. Esta região é uma das mais dinâmicas no cenário econômico brasileiro e representa 1,8% do PIB (Produto Interno Bruto) nacional e 11,45% do PIB paulista, ou seja, cerca de 91,8 bilhões de reais. Além de possuir uma forte economia, a região também apresenta uma infraestrutura que proporciona o desenvolvimento de toda a área metropolitana. O cenário acima resulta em uma rede elétrica em expansão contínua, levando à elevação gradativa dos níveis de curto circuito. Com a previsão de superação da capacidade interruptiva em diversos módulos de manobra, as empresas concessionárias que atuam nessa região precisaram elaborar esquemas provisórios de operação de suas instalações de forma radializada, através da abertura de linhas e barramentos. Este trabalho analisa a viabilidade da solução deste problema através da instalação de dispositivos limitadores de curto circuito em determinados locais do sistema, especificamente reatores com núcleo de ar. Os resultados apresentados servirão como referência para tomada de decisão quanto a proceder ou não com as substituições originalmente planejadas. Um estudo sobre os efeitos colaterais resultados da instalação dos reatores também é apresentado, de forma a garantir que a solução sugerida não resulte em transgressão de outros critérios técnicos, tais como violação do perfil de tensão e carregamento em regime permanente e dos limites de tensão de restabelecimento transitória / Abstract: This master thesis presents a study on the application of limiting reactors for reducing the short circuit level of sub-transmission networks. The objective is to postpone or avoid the replacement of large amount of circuit breakers and other equipment due to the overcoming of their interruptive capacity. The system under consideration consists of the 138 kV CPFL network, responsible for supplying electricity to the metropolitan region of Campinas, in the state of São Paulo. This region presents a very dynamic economic scenario in Brazil, and represents 1,8% of national GDP about 91,8 billion Reais (Gross Domestic Product) and 11,45% of GDP of the São Paulo State. Besides having a strong economy, the region also maintains an infrastructure that provides the development of the entire metropolitan area. The above scenario results in an electric grid on continuous expansion, leading to progressive increase of the short circuit level on several buses of the network. Following the projection of interruptive capacity overcoming of several maneuver elements, the distribution utilities in this region were requested to elaborate operation schemes for their sub-transmission networks in order to accommodate the new situation. Such schemes leaded to temporary radial operation by opening sub-transmission lines and bus bars. This research work evaluate the viability of solving this problem by installing limiting devices for the short circuit levels, specifically air core reactors, in pre-determined sites of the system. The obtained results are useful as a reference for the decision making as to proceed or not with the originally planned replacements. A study on the side effects resulting from the installation of the reactors is also presented, in such a way to guarantee that the suggested solution does not result in violations of other technical criteria, such as steady state voltage end load violations or transient voltage recovery violations / Mestrado / Energia Eletrica / Mestre em Engenharia Elétrica

A pesquisa se deu a partir da análise da confluência dos conteúdos vivenciados no corpo deste intérprete, na realização de pesquisas de campo no eixo Co-Habitar com a Fonte. A inquietação para a presente pesquisa originou-se no processo anterior, pois a incorporação da personagem Jura, a força que ela trouxe para meu corpo, e a maneira como este passou a criar e se expressar, levaram-me ao questionamento: "quando deixar de dançar 'A Flor do Café', e passar para um novo co-habitar, o que poderá acontecer com Jura? Ela deixará de existir? Se transformará? Como será a interação dos conteúdos no corpo?". A pesquisa de mestrado veio como uma oportunidade para experimentar essa transição e interseção de processos corporais, analisando-os e trazendo-os à tona.!Para tanto, foram realizadas quatro idas a campo do eixo Co-habitar com a Fonte, em campos de qualidades corporais distintas: duas delas no Jalapão, e duas no Bico do Papagaio, ambas regiões do Tocantins. No Jalapão, o foco do co-habitar se deteve nas mulheres artesãs do Capim Dourado, e algumas das manifestações que permeiam seu universo, como a brincadeira da Roda-Chata e a reza da sexta feira da Paixão, junto à Festa dos Caretas (personagens denominados "fantasmas"). No Bico do Papagaio, o foco esteve nas mulheres quebradeiras de coco babaçu e no Terecô, manifestação religiosa agrária, presente no cotidiano destas / Abstract: The objective of this research was to study and analyze the development of dancer-performer-researcher who has previously passed through an artistic process in the DRP method (Dancer-Researcher-Performer). The research took place from the analysis of the confluence of contents experienced in the body of this interpreter, while she was in research field on axis Co-Inhabiting with the Source. The concern for this research originated in the previous process, because the incorporation of Jura character, the strength she brought to my body, and the way it went on to create and express themselves, they took me to the question: "when I stop dancing 'The Flower of Coffee', and move to a new co-dwelling, which may happen to Jura? Will she cease to exist? Will she transform into a new character ? How will be the interaction of the contents in the body? ". The master's research came as an opportunity to experience this transition and intersection of body processes, analyzing them and bringing them to light. To do so, there were four trips to the field on axis Co-Inhabiting with the Source, in different fields of body qualities: two of them in Jalapao, and two in Bico do Papagaio, both regions of Tocantins. At Jalapao, the co-inhabiting was focused on women artisans that work with golden grass, and some of the manifestations that permeate their universe, as the play of Roda-Chata, the prays of the Good Friday, and the Festa dos Caretas (characters called "ghosts"). In Bico do Papagaio, the focus was on female babassu coconut breakers and Terecô, a agrarian religious manifestation, present in the daily life of them / Mestrado / Artes da Cena / Mestra em Artes da Cena

The UK Government has identified that nearly 15% of the UK’s electricity generation must come from offshore wind by 2020. The reliability of the offshore windfarms and their electrical transmission systems is critical for their feasibility. Offshore windfarms located more than 50-100km from shore, including most Round 3 offshore windfarms, are likely to employ Voltage Source Converter (VSC) High Voltage Direct Current (HVDC) transmission schemes. This thesis studies factors which affect the reliability of VSC-HVDC transmission schemes, in respect to availability, protection, and system modelling. The expected availability of VSC-HVDC systems is a key factor in determining if Round 3 offshore windfarms are technically and economically viable. Due to the lack of publications in this area, this thesis analyses the energy availability of a radial and a Multi-Terminal (MT) VSC-HVDC system, using component reliability indices derived from academic and industrial documentation, and examining the influence of each component on the system’s energy availability. An economic assessment of different VSC-HVDC schemes is undertaken, highlighting the overall potential cost savings of HVDC grids. The connection of offshore windfarms to a MT HVDC system offers other potential benefits, in comparison to an equivalent radial system, including a reduction in the volume of assets and enhanced operational flexibility. However, without suitable HVDC circuit breakers, a large MT HVDC system would be unviable. In this thesis, a review of potential HVDC circuit breaker topologies and HVDC protection strategies is conducted. A HVDC circuit breaker topology, which addresses some of the limitations of the existing designs, was developed in this thesis, for which a UK patent application was filed. Accurate simulation models are required to give a high degree of confidence in the expected system behaviour. Modular Multi-level Converters (MMCs) are the preferred HVDC converter topology, however modelling MMCs in Electromagnetic Transient (EMT) simulation programs has presented a number of challenges. This has resulted in the development of new modelling techniques, for which the published validating literature is limited. In this thesis these techniques are compared in terms of accuracy and simulation speed and a set of modelling recommendations are presented. Cable models are the other main DC component which, upon analysis, is found to have a significant impact on the overall model’s simulation results and simulation time. A set of modelling recommendations are also presented for the leading cable models. Using the modelling recommendations to select suitable MMC models, radial and MT EMT MMC-HVDC models for the connection of typical Round 3 windfarms are developed in this thesis. These models are used to analyse the steady-state and transient performance of the connections, including their compliance to the GB grid code for AC disturbances and reactive power requirements. Furthermore, the MT model is used to investigate the effect of MT control strategies on the internal MMC quantities.
