    Flame Front Propagation in an Optical GDI Engine under Stoichiometric and Lean Burn Conditions

    Lean fueling of spark ignited (SI) engines is a valid method for increasing efficiency and reducing nitric oxide (NOx) emissions. Gasoline direct injection (GDI) allows better fuel economy with respect to the port-fuel injection configuration, through greater flexibility to load changes, reduced tendency to abnormal combustion, and reduction of pumping and heat losses. During homogenous charge operation with lean mixtures, flame development is prolonged and incomplete combustion can even occur, causing a decrease in stability and engine efficiency. On the other hand, charge stratification results in fuel impingement on the combustion chamber walls and high particle emissions. Therefore, lean operation requires a fundamentally new understanding of in-cylinder processes for developing the next generation of direct-injection (DI) SI engines. In this paper, combustion was investigated in an optically accessible DISI single cylinder research engine fueled with gasoline. Stoichiometric and lean operations were studied in detail through a combined thermodynamic and optical approach. The engine was operated at a fixed rotational speed (1000 rpm), with a wide open throttle, and at the start of the injection during the intake stroke. The excess air ratio was raised from 1 to values close to the flammability limit, and spark timing was adopted according to the maximum brake torque setting for each case. Cycle resolved digital imaging and spectroscopy were applied; the optical data were correlated to in-cylinder pressure traces and exhaust gas emission measurements. Flame front propagation speed, flame morphology parameters, and centroid motion were evaluated through image processing. Chemical kinetics were characterized based on spectroscopy data. Lean burn operation demonstrated increased flame distortion and center movement from the location of the spark plug compared to the stoichiometric case; engine stability decreased as the lean flammability limit was approached

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2011Este trabalho realiza uma análise das personagens femininas do romance Pedro Páramo, de Juan Rulfo, de 1955. Investiga como foi construída a representação das mulheres e como se constituem ficcionalmente as relações entre homem e mulher na sociedade do período da Revolução Mexicana. Para compreender como Rulfo constrói tais personagens, seleciono algumas delas, a partir de pesquisa bibliográfica documental e ficcional, e desenvolvo uma leitura sobre a construção desses papeis femininos. A construção estético e ficcional de perfis psicológicos do romance procura mostrar uma sociedade rural em decadência, onde o cotidiano e as relações são regidos pelo desencanto e pela (des)esperança de uma outra história.This dissertation analyzes the female characters in the romance novel "Pedro Paramo", written by Juan Rulfo in 1955. The novel investigates the construction of the representation of women and how they fictionally constitute the relations between men and women in the society of the Mexican Revolutionary era. To understand how Rulfo creates these personages, I select some of them, and through documentary and fictional bibliographic research, I develop a reading on the construction of these female roles. The aesthetic and fictional development of the psychological profiles of this romance novel attempts to show a decadent rural society where everyday life and relationships are governed by disenchantment and the hope(lessness) of a different story

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Ciência da Computação, Florianópolis, 2013.Este trabalho apresenta primeiramente uma pesquisa que tem como foco a investigação da relação da carga elétrica com a temperatura ambiente para a Ilha de Santa Catarina, e a influência da temperatura na precisão da previsão de carga elétrica de curto prazo, em diferentes faixas de temperatura. A partir dos dados históricos de carga e temperatura, foi construída uma aproximação polinomial de terceiro grau da relação carga versus temperatura, onde a curva resultante mostra a influência da temperatura sobre o comportamento da carga e o relacionamento não linear entre estas variáveis. Foi verificado, para a região estudada, que existe uma faixa central de temperatura com pouca influência no consumo, enquanto que acima ou abaixo desta faixa, existem, respectivamente, relações significativas direta e inversa com o comportamento da carga. Ainda que, a precisão da previsão da carga horária por uma rede neural é afetada pela faixa de temperatura considerada. Outra contribuição desta dissertação é a proposta de um método de correção para a rede neural que minimiza o erro de previsão gerado pelas faixas de temperatura que mais afetam a previsão de carga. Os estudos experimentais indicaram que uma rede neural que inicialmente apresentava instabilidade quando submetida a variações de temperatura, após sua correção, conseguiu diminuir seus erros de previsão a índices muito próximos a dias normais. Abstract : This work first presents a research that has focused on the investigation of the relationship between electric load and temperature in the Island of Santa Catarina and the influence of the temperature on short-term load forecasting regarding different temperature intervals. Based on historic data of load and temperature, it is built a load over temperature curve from a third-degree polynomial approximation, which is used to estimate the influence of the temperature on the load and the nonlinear relationship between these variables. For the studied region it has been shown that there is a central temperature interval with minimum influence on demand, while above and below that interval, respectively, direct and inverse relationships with the behavior of the load is observed. Furthermore, the load prediction accuracy of a neural network is affected by the temperature range considered. This study may produce as result a better scaling on load demand, resulting in financial gain to the distributors. Based on this knowledge we propose a correction method for the neural network that minimizes the prediction error generated by the temperature ranges that most affect the load forecasting. Experimental studies suggested that a neural network which initially showed instability when subjected to temperature changes after correction, managed to reduce forecast error to rates very similar to the normal days

    TCC (graduação) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Curso de Ciências Sociais.O artigo reflete sobre o uso do humor no ensino de conteúdos sociológicos, políticos e antropológicos no Ensino Médio, bem como sua contribuição para reflexão crítica. Procura-se, a partir de experiência em estágio de docência no curso de Ciências Sociais da Universidade Federal de Santa Catarina (UFSC), compreender como o humor – pela ironia, sarcasmo, riso etc. – interfere no processo de ensinoaprendizagem. Investigam-se conceitos referentes ao humor e suas diferentes manifestações, enfatizando sua relação com a compreensão e a construção de conceitos sociológicos, políticos e antropológicos, através do enfrentamento de uma linguagem exclusivamente acadêmica e científica, que pode distanciar o estudante do conhecimento. Esse enfrentamento se dá na analise crítica sobre discurso, disciplina, relações de poder, verdade, ciência, e linguagem, por meio de conceitos de Michel Foucault, Pierre Bourdieu e Giorgio Agamben, entre outros autores. Observou-se a alteração positiva no comportamento e no aprendizado dos estudantes em sala, em comparação às aulas antes ministradas pela professora da disciplina, de postura tradicional em aulas expositivas e conteudistas. O trabalho pretende contribuir para o ensino de uma sociologia reflexiva e crítica mais próxima dos jovens, ao utilizar uma linguagem que lhes é familiar.The article reflects about the use of humour in teaching sociological, political and anthropological contentes in high school, as well as its contribution to critical reflection. We seek, through the teaching stage experience in the course of Ciências Sociais, Universidade Federal de Santa Catarina (UFSC), to understand how the humour – by irony, sarcasm, laughing, etc. – affects teaching and learning. We investigat concepts related to humour and its different manifestations, emphasizing its relation to the understanding and construction of sociological, political and anthropological concepts, through a confrontation with an exclusively academic and scientific language, which can hold off the student from knowledge. This confrontation occurs in the critical analysis of the concepts discourse, discipline, power relations, truth, science and language, by Michel Foucault, field and symbolic capital of Pierre Bourdieu, profanation of Giorgio Agamben, among others. We observed a positive change in the behavior and students learning, compared to the classes taught by the teacher of the discipline, whose stance was expressed by the traditionalism of an expository and contentbased lecture. The paper intends to contribute for the teaching of a critical and reflexive sociology nearest to young people, using language familiar to them

    A importância do riso no pensamento de Eça de Queirós e Nietzsche: o que pode o riso contra o niilismo?

    No full text
    Esta dissertação apresenta uma análise do riso em Eça de Queirós e Nietzsche com o objetivo de demonstrar como este não é um tema periférico no pensamento de ambos os autores. Em particular no caso de Nietzsche, cujo estilo de escrita aforística eleva a dificuldade de sistematização do tema pela dispersão das referências ao riso ao longo da sua obra, mas por essa mesma razão nos leva a concluir pela importância central do tema no seu pensamento. Procurámos estabelecer uma análise do pensamento dos autores por comparação com a tradição filosófica sobre o riso (Teoria da Superioridade, Teoria do Alívio e Teoria da Incongruência) propondo assim avaliar em que medida se aproximam ou afastam dessa mesma tradição. Ambos reconhecem a importância do riso como forte instrumento de crítica e afirmação, e que a presença ou ausência do riso diferencia a nossa atitude perante a condição humana. Nestes aspetos reside a originalidade do riso em Eça de Queirós e Nietzsche e que, em nosso entender, os aproxima. Procurámos demonstrar como o riso é um instrumento de luta contra ao niilismo, e que os autores em análise defendem que esse combate pode ser levado a cabo através de uma atitude humorística e afirmativa (a qual tem de incluir a capacidade de o homem ser capaz de rir de si próprio), e que esta é compatível com a constatação do absurdo e do sentido trágico da vida.This dissertation presents an analysis of laughter in Eça de Queirós and Nietzsche with the aim of demonstrating how this is not a peripheral theme in the thought of both authors. Particularly in the case of Nietzsche, whose style of aphoristic writing elevates the difficulty of systematizing the theme by the dispersion of references to laughter throughout his work, but for that very reason leads us to conclude the central importance of the theme in his thought. In both cases, we tried to establish an analysis of the authors' thinking by comparison with the philosophical tradition about laughter (Theory of Superiority, Theory of Relief and Theory of Incongruity), thus proposing to evaluate the extent to which they approach or depart from that same tradition. Both recognize the importance of laughter as a strong instrument of criticism and affirmation, and that the presence or absence of laughter differentiates our attitude towards the human condition. In these aspects lies the originality of laughter in Eça de Queirós and Nietzsche that brings them together. It is to this extent that we have attempted to demonstrate how laughter is an instrument of struggle against nihilism by proposing that the authors in question argue that such a struggle can be carried out through a humorous and affirmative attitude (which must include the capacity of the man to be able to laugh at himself), and that this attitude is compatible with the realization of the absurd and the tragic sense of lif
