FLAT! immerses us into the life and mindset of a Flat-earther who eagerly evangelizes the discoveries he and other Flat-earthers claim to have made. With his car clad in flat-earth messages, he travels around the country provoking discussions with curious bystanders and debating scientists. While he thrives in this pursuit, it is not without its costs.

Doutoramento em MúsicaEsta dissertação pretende projectar A Presença da Flauta Traversa em Portugal de 1750 a 1850. Tendo como um dos principais objectivos reunir, pela primeira vez, num só documento, o maior número possível de instrumentos dos construtores nacionais, foram localizadas um total de dezoito flautas traversas e um flautim. Deste instrumentário, quinze são provenientes da família Haupt, três da família Silva e um do construtor Xavier Paranho. O primeiro capítulo incide na abordagem historiográfica do instrumento, no segundo capítulo efectua-se o estudo organológico das flautas traversas nacionais, o terceiro capítulo é dedicado às fichas de identificação técnica de cada instrumento e, por último, a inserção da flauta traversa no repertório e no ensino, em Portugal, é tratada no capítulo quatro. A abordagem das obras setecentistas de António Rodil (c.1710-1788), Pedro António Avondano (1714- 1788) e Fr. Manuel dos Santos Elias (c.1740-c.1780), e o repertório oitocentista de João D. Bomtempo (1775-1842), José Maria da Silva (1789-?), José Maria Ribas (1796-1861), António José Croner (1826-1888), José Francisco Arroio (1818-1868) e João Parado (?-1842), assim como, o método para flauta coordenado por Cézar Augusto P. das Neves (1841-1920), encerram este projecto.
This dissertation intends to project the presence of the transverse flute in Portugal from 1750 to 1850. One of its main aims is to bring together for the first time, in one document, the largest possible number of instruments by national builders. In the wake of this research, eighteen transverse flutes and one piccolo flute have been located. Within this set of instruments, fifteen were built by the Haupt family, three from the Silva family, and one from Xavier Paranho. The dissertation’s first chapter offers a historiographic overview of the transverse flute. In the second chapter an organologic study of the national transverse flutes is laid out. The third chapter addresses the specifications of each instrument, while the final chapter deals with the presence of the flute in Portuguese musical literature and teaching repertoire. An overview of 17th century compositions of António Rodil (c. 1710-1788), Pedro António Avondano (1714-1788), and Fr. Manuel dos Santos Elias (c. 1740-1780); the 18th century repertoire of Joâo D. Bomtempo (1775-1842), José Maria da Silva (1789-?), José Maria Rivas (1796-1861), António José Croner (1826-1888), José Francisco Arroio (1818-1868) and João Parado (?-1842); and the flute method conceived by Cézar Augusto P. das Neves (1841-1920) conclude this dissertation.

Full textAbstract:
The investigation of progressive collapse of buildings has been of special interests during the last decade. The aim of this study is to assess the influence of selected design parameters on the vulnerability of structures with flat plates or flat slabs to progressive collapse triggered by the severe damage or failure of a column as a result of accidental or maliciously intended terrorist activity. The variables of frames with two-way slab systems investigated include: the number of stories in buildings (low-, medium- and high-rise buildings), span ratio (the ratio of span lengths in two orthogonal directions), span length for square panels, as well as the effect of having flat plates compared to flat slabs detailed either as ordinary gravity load carrying systems or by following the seismic detailing requirements of the Canadian practice as per CSA A23.3-04.
The linear-elastic static analysis method, outlined in the General Services Administration (GSA) guidelines of the US, was employed to conduct a parametric investigation to assess the significance of the design variables considered on progressive collapse potentials of buildings. This involved the computation of demand/capacity ratios (DCR) Higher DCRs were obtained for buildings with increased number of stories and span ratios, while the change in span lengths did not show a clear trend. Also, flat slabs were less vulnerable, and experienced smaller DCRs, than flat plates. Buildings detailed according to the seismic provisions of CSA A23.3-04 were less vulnerable than those detailed without these provisions. However, both slabs with non-seismic and seismic detailing required improvements in terms of the percentage of top and bottom reinforcement and bar lengths, depending on the slab type and the design parameters considered.

The thesis is focused on the chamber music pieces with flute composed by Bohuslav Martinů. One of the sub-chapters is dedicated to Concert for Flute, Violin and Orchestra, but only because of its close connection to chamber pieces for these instruments. The chapter about the life of Bohuslav Martinů is brief and is focused only on the most important facts from this area. In the second chapter there are sonatas, trios, sextets, nonets, etc. and all those pieces have their own historical ? esthetic commentary, basic info about their origination, manuscripts, issues etc. For chosen pieces (Sonata for Flute, Violin and Piano, Sonata for Flute and Piano, Promenades, Sextet) there is dedicated detailed analysis, especially formal and harmonious analysis. The interpretative problems are also one of the goals I tried to achieve altogether with my points of view of these musical pieces and their interpretation

We propose in this thesis a way to study deformations of plane curves that take into consideration the geometry of the curves as well as their singularities. We deal in details with local phenomena that occur generically in two-parameter families of curves. We obtain information on the inflections and vertices appearing on the deformed curves. We also obtain the configurations of the evolutes of the curves and of their deformations, and apply our results to orthogonal projections of space curves. Finally, we consider the profile (outline, apparent contour) of a smooth surface in the Euclidian 3-space. This is the image of the singular set of an orthogonal projection of the surface. The profile is a plane curve and may have singularities. We study the changes in the geometry of the profile as the direction of projection changes locally in the unit sphere.Propomos nesta tese um método para estudar deformações de curvas planas que leva em consideração a geometria delas, bem como as suas singularidades. Consideramos em detalhes os fenômenos locais que ocorrem genericamente em famílias de curvas com dois parâmetros. Obtemos informações sobre as inflexões e vértices que aparecem nas curvas deformadas. Obtemos também as configurações das evolutas das curvas e das suas deformações e aplicamos os nossos resultados nas projeções ortogonais de curvas espaciais. Finalmente, consideramos o perfil de uma superfície regular no espaço Euclidiano R3. O perfil é a imagem do conjunto singular de uma projeção ortogonal da superfície, esta é uma curva plana e pode ter singularidades. Estudamos as alterações na geometria do perfil quando a direção de projeção muda localmente na esfera unitária.

Full textAbstract:
The use of flat slabs in constructions due to its many functional and economic advantages is wide-spread. Behavior of flat slabs in shear and flexure is a fairly complex problem. Therefore, the punching shear failure belongs to one of the most critical aspects in the design of concrete buildings. Over the last decades several buildings have collapsed due to the failure of the punching shear strength, resulting in loss of lives and financial damages. These disasters revealed gaps in the current (or former) design codes and recommendations. As a part of theoretical framework of the dissertation a method for predicting the punching shear strength of flat slabs was developed. Several experiments on scaled down slabs were conducted in order to verify the proposed method and for optimization of its parameters. Proposed method in development predicts the punching shear for slabs without shear reinforcement according to the EC2 and replaces the area of the shear crack with a system of struts and ties.

Full textAbstract:
Wir untersuchen und berechnen Welleninvarianten von Schrödinger-Operatoren, die auf Schnitte von Hermiteschen Geradenbündeln über flachen Tori gerader Dimension wirken. Die Schrödinger-Operatoren werden aus einem translationsinvarianten Zusammenhang des Bündels sowie einem Potential, d.h. einer glatten Funktion auf dem Torus, konstruiert. Wir beschränken uns auf Bündel mit nichtentarteter Chern-Klasse und untersuchen, in welchem Umfang das Spektrum eines Schrödinger-Operators mit gegebenem Potential den Zusammenhang bestimmt.
Wir berechnen die ersten fünf Welleninvarianten explizit mittels des Computeralgebrasystems Mathematica. Für einfache Potentiale erhalten wir eine vollständige Charakterisierung der Isospektralität der translationsinvarianten Zusammenhänge. Weiterhin werden allgemeine Eigenschaften der Welleninvarianten bewiesen, welche allgemeinere Aussagen über die Existenz nichtisospektraler Zusammenhänge implizieren. Andererseits ergeben sich Erkenntnisse über die Grenzen der spektralen Information, die in endlich vielen Welleninvarianten enthalten ist.
Negative spektrale Ergebnisse, d.h. Unterschiede in den Zusammenhängen, die nicht durch das Spektrum bestimmt werden, werden durch die Konstruktion von Transplantationen zwischen den Schrödinger-Operatoren zweier Zusammenhänge bei gleichem Potential bewiesen.We study and compute wave invariants of Schrödinger operators acting on sections of Hermitian line bundles over even-dimensional flat tori. The Schrödinger operators are constructed from translation-invariant connections on the bundle and a potential, a smooth function on the torus. Restricting to bundles with nondegenerate Chern class we study the extent to which the spectrum of the Schrödinger operator of a given potential determines the connection. The first five wave invariants are computed explicitly using the computer algebra software Mathematica. For simple potentials we find a full characterization of the isospectrality of the translation-invariant connections. We also prove general properties of the wave invariants, which imply a more general existence of nonisospectral connections but which also show limitations of the spectral information contained within finitely many wave invariants. Negative spectral results, i.e. differences in connections not determined by spectra, are obtained by constructing transplantations between the Schrödinger operators of two connections with a fixed potential.

Previous issue date: 2011-08-19Mesmo que cientistas tenham demonstrado, até agora, que os materiais utilizados na construção de flautas pouco interferem em suas respectivas características sonoras,parece que algo ainda está em aberto, pois diversos músicos ainda insistem no fato de que o material utilizado na construção de flautas influencia de forma significativa o som produzido. Assim na busca por resultados que possam contribuir nessa discussão, foi realizado um estudo acústico com três pares de tubos de dimensões idênticas,sendo dois de alumínio, dois de cobre e dois de latão, com o propósito de comparar seus respectivos sons harmônicos em três experiências semelhantes: (Experiência 1) tubos acoplados a um bocal de flauta doce,contralto,da marca Yamaha,tocadas por um flautista; (Experiência 2) tubos acoplados a um bocal de flauta transversal,em fibra de carbono,especialmente construído para este trabalho,tocadas por outro flautista; (Experiência 3) tubos acoplados ao mesmo bocal de flauta doce, contralto, da marca Yamaha, tocadas por um soprador artificial alimentado por um cilindro de gás nitrogênio (99,9% de pureza) com fluxo controlado e contínuo.

Full textAbstract:
Observa-se que a maioria das metodologias utilizadas no ensino da flauta doce, no Brasil, prioriza o desenvolvimento de habilidades de execução e leitura. Por outro lado, constata-se uma carência de publicações que abordem reflexões sobre processos de aprendizagem deste instrumento. Por estas razões, a presente pesquisa procurou sistematizar e analisar, dentre as práticas de ensino da autora, propostas voltadas para um ensino criativo, reflexivo, que buscam uma aproximação com a linguagem musical contemporânea e que poderiam contribuir para o alargamento de horizontes pedagógicos e colaborar com o ensino da flauta doce no país, contribuir para a produção de conhecimentos na área, além de desenvolver capacidades humanas. O trabalho apoia-se teoricamente nos princípios pedagógico musicais de dois grandes educadores musicais: Hans-Joachim Koellreutter (1915-2005) e Violeta Hemsy de Gainza (1930-), além do pensamento de outros educadores como Paynter (1992), Brito (2001, 2003, 2004, 2007, 2012), Schafer (1992), Self (1967), Fonterrada (2008), entre outros, que complementam e ampliam ainda mais estes princípios. De natureza qualitativa, dentre as diversas modalidades existentes, este estudo caracteriza-se como relato de experiência. Os dados foram coletados em duas instituições de ensino superior de música da cidade de São Paulo: Faculdade de Artes Alcântara Machado (FIAM-FAAM) e Faculdades Integradas Cantareira (F.I.C.), entre 2013 e 2014, com crianças da Escola Municipal de Iniciação Artística (EMIA-SP), entre 2008 e 2012, e com uma aluna de 7 anos, em aulas particulares, entre 2013 e 2014. Os resultados demonstraram que os diversos procedimentos pedagógicos apresentados contribuíram para o alargamento de práticas musicais, desenvolvendo a técnica do instrumento, tanto tradicional quanto contemporânea. Os resultados também evidenciaram que a aproximação com o repertório dos séculos XX e XXI, no início do aprendizado, foi uma experiência inusitada, interessante, enriquecedora e dilatadora de fronteiras para a maioria dos alunos. Em aspectos humanos, o conjunto de atividades colaborou para o desenvolvimento da atenção e da prontidão, promovendo a autonomia, a tolerância, a generosidade e o respeito, mostrando-se como uma possibilidade de ampliação de metodologias já existentes.Most of the recorder teaching methods used throughout Brazil, as we could observe, chiefly contemplate the playing and reading skills development. Furthermore, there is a significant lack of publications specializing on the learning process study. Bearing these facts in mind and based on the author\'s experiments, this research is directed to systemize and analyze the attempts to come up with creative and reflexive plans, and look for approach to the contemporary musical language which would enlarging pedagogic horizons, contribute to the recorder teaching across the country, collaborate with the knowledge production in the area, as well as improving the development of human skills. This research is theoretically based on musical pedagogical principles by two major music educators: Hans-Joachim Koellreutter (1915-2005) and Violeta Hemsy of Gainza (1930-), complemented by other educators thoughts as Paynter (1992), Brito (2001 , 2003, 2004, 2007, 2012), Schafer (1992), Self (1967), Fonterrada (2008), among others who complemented and extended these principles. This research being a work of qualitative nature, among several existing studies, it is characterized as an experience report. The data were collected next to two advanced musical education institutions located in São Paulo: Faculdade de Artes Alcântara Machado (FIAM-FAAM) and Faculdades Integradas Cantareira (F.I.C.), between 2013-2014,as well as with children of the Arts Initiation Municipal School, Escola Municipal de Iniciação Artística (EMIA), between 2008-2012, and with a privately tutored 7- year old student, between 2013-2014.The outcome of those experiments showed that the various educational procedures presented have widened the musical practices, developing the technique of the instrument, both traditional and contemporary. It was also shown that the approach to the XX and XXI centuries\' repertoire when introduced early at the apprenticeship stage was an unusual experience, drawing interest and proving to be enriching and a border dilator to the most of the students. As far as human aspects are concerned, the activities contributed to the development of attentiveness, readiness, promoting autonomy, tolerance, generosity and respect, pointing up to the feasibility for the expansion of the existing methods.

Apóia-se na concepção de musicalidade como uma característica humana, constituída pela capacidade de geração de sentido musical através de uma performance expressiva. A metodologia de pesquisa possui abordagem qualitativa, com a realização de um estudo de caso em grupo por meio de observações de aulas e apresentações coletivas de flauta doce. Foram realizadas entrevistas semi-estruturadas como procedimento complementar. A coleta de dados aconteceu entre setembro de 2007 e agosto de 2008, totalizando 16 encontros, registrados em diário de campo e em arquivos de áudio. A observação dos indicadores sonoridade, fraseado, fluência na execução instrumental e interação musical otimizou a análise e interpretação dos resultados. O desenvolvimento da musicalidade dos sujeitos caracterizou-se por ser um processo dinâmico de aquisição gradativa de conhecimentos e habilidades musicais que promovem, a cada avanço, uma totalidade nova do saber-fazer que favorece a expressividade na performance. Os resultados demonstraram que o repertório, a prática e estudo, o contexto sociocultural, o acesso à técnica, criação e leitura musical e a ocorrência de apresentações musicais são fatores que influenciam o desenvolvimento da musicalidade.The present research traces the recorder learning process in a group of seventeen people, between the ages of nine and thirteen, which participate in an extension program held by a public school in Porto Alegre city. This research aims to understand how musicality is developed, based on the concept that this is a human characteristic, constituted by the capacity of creating musical meaning through expressive performance. The methodology applied has a qualitative approach. A group case study was made through class observation and collective recorder presentations. Semi-structured interviews were conducted as a complementary procedure. Data collection occurred between September 2007 and August 2008 by a total of 16 meetings registered in a field diary and in audio files. The observation of indicators such as sonority, musical phrasing, instrumental fluency and musical interaction optimized the analysis and interpretation of the results. The development of musicality in these seventeen people was characterized by the dynamic process of gradual acquisition of musical knowledge and ability, which promotes, at every progress, a new know-how wholeness that favors performance expressivity. The results demonstrated that: repertoire; practice and study; sociocultural context; access to technique, composition, improvisation, and musical reading; and the occurrence of musical presentations are factors that influence musicality development.

The aim of this work is to register and document the most important aspects of the life and work of João Dias Carrasqueira as a pioneer of the flute teaching in Brazil. It is based in a series of interviews given by João Dias Carrasqueira to the author of this work during the year of 1993, where he reports to his life as musician and a master of the flute. Interviews with other people connected to him have also been performed. Firstly, a brief biography of João Dias Carrasqueira is presented, refering to his nickname as Canarinho da Lapa, his first flute lessons and his professional activites as flutist in the cinema orchestras, during the years of 1920, and in the radios of São Paulo during the years of 1930. Emphasys is given to the ideas of João Dias Carrasqueira applied to the flute teaching and the connection to the ideas of other masters of pedagogy such as P.Freire, K.Swanwick, V.Gainza, and musicists like V. Lobos. The practice of chamber music and the formation of groups of students to play together were important features of his teaching process. João Dias Carrasqueira was one of the first flute teachers to introduce the Brazilian music repertoire into flute teaching. At last but not least we decribe his work developed with the children teaching, which involved the creation of drawings with the musical notes, of histories, and the image of little songs composed by him to the students. On the technical point of view, the sonority was of most importance for João Dias Carrasqueira. He stimulated the practice of exercises in order to improve the quality of the sound, always taking into account the individual characteristics of each student. Finally, we explore the meaning the expression Flautosofia created by João Dias Carrasqueira to manifest his attitude facing life and music.Este trabalho pretende registrar e documentar os aspectos mais importantes da biografia do professor João Dias Carrasqueira como flautista e pioneiro ensino da flauta no Brasil. Foi baseado em uma série de depoimentos do professor João Dias Carrasqueira recolhido durante o ano de 1993, onde ele relata sua vida como músico e mestre da flauta. Além dos depoimentos do professor João Dias Carrasqueira também foram feitas entrevistas e tomados depoimentos de várias pessoas a ele ligadas.Inicia-se com uma breve biografia, fazendo referência ao cognome Canarinho da Lapa, as primeiras lições de flauta transversal, os primeiros trabalhos profissionais em orquestras de cinema da década de 1920, e a partir da década de 1930, em emissoras de rádio, além de um relato de seu importante trabalho como flautista. Enfatizamos suas idéias aplicadas ao ensino de flauta, fazendo um paralelo com as idéias de outros educadores como Paulo Freire, K.Swanwick e V.Gainza e mestres da música como H.Villa-Lobos, no que se refere à utilização de elementos da própria cultura como veículo de aprendizagem. A utilização da música de câmara e o convívio permanente entre alunos são aspectos relevantes do seu processo de aprendizagem. João Dias Carrasqueira foi um dos primeiros a incluir o repertório de música brasileira no ensino de flauta. Ainda estão relacionados os recursos pedagógicos utilizados por ele com alunos iniciantes e principalmente com crianças como criação de desenhos, histórias e canções.Do ponto de vista técnico, a sonoridade era o aspecto de maior importância para o professor João Dias Carrasqueira. Ele estimulava a prática de exercícios que visassem o aperfeiçoamento da qualidade sonora, sempre respeitando as características individuais de cada estudante. Por último, nós exploramos o significado da expressão Flautosofia criada por João Dias Carrasqueira para manifestar a sua atitude diante da música e da vida.

Resumo: Esta pesquisa teve por objetivo explicitar o papel do espetáculo didático musical Doce Flauta Doce em atividades de apreciação musical do público infantil em ambiente escolar. Foi realizado um diagnóstico prévio do público infantil participante da pesquisa; analisou-se a influência desse espetáculo sobre o interesse das crianças em tocar um instrumento musical, bem como suas impressões e participações diante do espetáculo; e foram especuladas as possibilidades de aprendizagem musical decorrentes do espetáculo. No primeiro capítulo é apresentado o concerto didático como uma forma de ensino musical informal e exemplos de projetos estruturados envolvendo este tema. No capítulo seguinte apresentam-se reflexões de educadores musicais sobre a apreciação musical e sua função no ensino musical. A metodologia adotada foi estudo de caso, que incluiu duas apresentações do espetáculo didático musical Doce Flauta Doce, no ano de 2015, em uma escola pública do município de Curitiba. O instrumento de pesquisa adotado consiste em questionários com três categorias de público participantes desta experiência: as crianças, os professores e os músicos envolvidos, e, complementarmente, em desenhos elaborados pelas crianças após o espetáculo. Pôde-se concluir que as crianças, por meio do espetáculo, entraram em contato com a diversidade de instrumentos, puderam compará-los, analisá-los, e também conhecer como funcionam. Além disso, percebeu-se que quando solicitadas a participar da performance, o grau de engajamento e atenção aumenta consideravelmente. Com esta pesquisa constata-se que o espetáculo didático musical Doce Flauta Doce, por meio da apreciação musical ao vivo, propiciou a aproximação das crianças à música instrumental, com liberdade expressiva, despertando nelas a curiosidade pelo diferente (independente de seu gosto musical), e proporcionando autonomia para que pudessem realizar as suas próprias conexões entre o que viram e escutaram, e suas próprias experiências com a música. Palavras-chave: Flauta doce. Espetáculo didático musical. Apreciação musical. Ambiente escolar.
Abstract: This research aimed to explain the role of the didactic musical spectacle Doce Flauta Doce on music listening of children's audience in the school environment. First, it was made a previous diagnosis of the child audience participant of the research. Then, the influence of this spectacle on children's interest in playing a musical instrument was analyzed, as well as their impressions of the spectacle, and their participation in it. The possibilities of musical learning resulting from the spectacle were speculated. The first chapter presents the didactic concert as a form of informal music teaching and also some examples of structured projects involving this subject. The next chapter presents some reflections of music educators on music listening and their role in music teaching. The methodology used was case study, which included two performances of the didactic musical spectacle Doce Flauta Doce, in 2015, in a public school in the city of Curitiba. The research instrument adopted consisted of questionnaires applied to three categories of people that participated in this experience: children, teachers and musicians. Additionally, the research instrument consisted also of drawings produced by the children after the spectacle. It was possible to conclude that children, thanks to the spectacle, came into contact with the diversity of instruments, could compare them, analyze them, and also know how they work. Moreover, it was noticed that when asked to participate in the performance, the degree of engagement and attention has increased considerably. As a result of this research it appears that the didactic musical spectacle Doce Flauta Doce, through the live music listening, propitiated the approximation of children to the instrumental music, with expressive liberty, awakening in them the curiosity about the unknown (regardless of their musical tastes), and providing them autonomy to make their own connections between what they saw and listened and their own experience with music. Keywords: Recorder. Didactic musical spectacle. Music listening. School environment.

En esta tesis doctoral se presentan diversos métodos para la linealización de sistemas de control no lineales o para el estudio de la platitud. Se utilizan dos aproximaciones diferentes, en concreto: geometría diferencial y álgebra diferencial.En el marco de álgebra diferencial, se presenta un estudio de los sistemas lineales de control desde la perspectiva de la teoría de módulos. A pesar de que los resultados han sido establecidos previamente por otros autores, algunas demostraciones y ejemplos son originales.
Entre las nuevas demostraciones cabe resaltar la que se refiere a la equivalencia entre sistemas de control lineales en representación de variables de estado, y los módulos sobre un anillo de operadores diferenciales. Los resultados de este estudio son ampliamente utilizados en el desarrollo de otros capítulos de la tesis en los que se usa el álgebra diferencial. En este contexto las principales contribuciones son:
Una nueva demostración del hecho, bien conocido, que la linealización por realimentación estática y la linealización por realimentación dinámica son equivalentes en el caso de sistemas de entrada simple. Para la linealización de este tipo de sistemas, se desarrolla un nuevo algoritmo.
Un procedimiento teórico para linealizar sistemas de entrada múltiple, basado en el cociente de módulos. También se ha hecho un paquete informático para llevar a cabo los cálculos necesarios. Debe mencionarse que este procedimiento es válido para linealizar sistemas mediante realimentación estática, así como para sistemas que sólo puedan linealizarse mediante realimentación dinámica.
Una condición para comprobar si las salidas linealizantes encontradas pueden obtenerse mediante prolongaciones. Como aplicación, se muestran algunos ejemplos de sistemas linealizables por prolongaciones. Algunos de estos sistemas se creían que no eran linealizables mediante esta técnica.

Full textAbstract:
This work treats the thermal and mechanical performances of gas-filled, flat plate solar collectors in order to achieve a better performance than that of air filled collectors. The gases examined are argon, krypton and xenon which all have lower thermal conductivity than air. The absorber is formed as a tray connected to the glass. The pressure of the gas inside is near to the ambient and since the gas volume will vary as the temperature changes, there are potential risks for fatigue in the material. One heat transfer model and one mechanical model were built. The mechanical model gave stresses and information on the movements. The factors of safety were calculated from the stresses, and the movements were used as input for the heat transfer model where the thermal performance was calculated. It is shown that gas-filled, flat plate solar collectors can be designed to achieve good thermal performance at a competitive cost. The best yield is achieved with a xenon gas filling together with a normal thick absorber, where normal thick means a 0.25 mm copper absorber. However, a great deal of energy is needed to produce the xenon gas, and if this aspect is taken into account, the krypton filling is better. Good thermal performance can also be achieved using less material; a collector with a 0.1 mm thick copper absorber and the third best gas, which is argon, still gives a better operating performance than a common, commercially produced, air filled collector with a 0.25 mm absorber. When manufacturing gas-filled flat plate solar collectors, one way of decreasing the total material costs significantly, is by changing absorber material from copper to aluminium. Best yield per monetary outlay is given by a thin (0.3 mm) alu-minium absorber with an argon filling. A high factor of safety is achieved with thin absorbers, large absorber areas, rectangular constructions with long tubes and short distances between glass and absorber. The latter will also give a thin layer of gas which gives good thermal performance. The only doubtii ful construction is an argon filled collector with a normal thick (> 0.50 mm) aluminium absorber. In general, an assessment of the stresses for the proposed construction together with appropriate tests are recommended before manufacturing, since it is hard to predict the factor of safety; if one part is reinforced, some other parts can experience more stress and the factor of safety actually drops.

Full textAbstract:
In this work we analyze various implications of the presence of large field vacum expectation values (VEVs) along supersymmetric flat directions during the early universe. First, we discuss supersymmetric leptogenesis and the gravitino bound. Supersym- metric thermal leptogenesis with a hierarchical right-handed neutrino mass spectrum normally requires the mass of the lightest right-handed neutrino to be heavier than about 109 GeV. This is in conflict with the upper bound on the reheating temperature which is found by imposing that the gravitinos generated during the reheating stage after inflation do not jeopardize successful nucleosynthesis. We show that a solution to this tension is actually already incorporated in the framework, because of the presence of flat directions in the supersymmetric scalar potential. Massive right- handed neutrinos are efficiently produced non-thermally and the observed baryon asymmetry can be explained even for a reheating temperature respecting the gravitino bound if two conditions are satisfied: the initial value of the flat direction must be close to Planckian values and the phase-dependent terms in the flat direction potential are either vanishing or sufficiently small. We then show that flat directions also contribute to the total curvature perturbation. Such perturbation is generated at the first oscillation of the flat direction condensate when the latter relaxes to the minimum of its potential after the end of inflation. If the contribution to the total curvature perturbation from supersymmetric flat direction is the dominant one, then a significant level of non-Gaussianity in the cosmological perturbation is also naturally expected. Finally, we argue that supersymmetric flat direction VEVs can decay non perturbatively via preheating even in the case where they undergo elliptic motion in the complex plane instead of radial motion through the origin. It has been generally argued that in this case adiabaticity is never violated and preheating is inefficient. Considering a toy U(1) gauge theory, we explicitly calculate the scalar potential, in the unitary gauge, for excitations around several flat directions. We show that the mass matrix for the excitations has non-diagonal entries which vary with the phase of the flat direction vacuum expectation value. Furthermore, this mass matrix has zero eigenvalues whose eigenstates change with time. We show that these light degrees of freedom are produced copiously in the non-perturbative decay of the flat direction VEV.

Given a prime number p, Bloch and Kato showed how the p Selmer group of an abelian variety A over a number field K is determined by the p-adic Tate module. In general, the pm1-Selmer group Selpmn A need not be determined by the mod pm Galois representation A[pm]; we show, however, that this is the case if p is large enough. More precisely, we exhibit a finite explicit set of rational primes E depending on K and A, such that Selpm A is determined by A[pm] for all ... In the course of the argument we describe the flat cohomology group ... of the ring of integers of K with coefficients in the pm- torsion A[pm] of the Neron model of A by local conditions for p V E, compare them with the local conditions defining Selm 2A, and prove that A[p't ] itself is determined by A[pm] for such p. Our method sharpens the relationship between Selpm A and ... which was observed by Mazur and continues to work for other isogenies 0 between abelian varieties over global fields provided that deg o is constrained appropriately. To illustrate it, we exhibit resulting explicit rank predictions for the elliptic curve 11A1 over certain families of number fields. Standard glueing techniques developed in the course of the proofs have applications to finite flat group schemes over global bases, permitting us to transfer many of the known local results to the global setting.

Full textAbstract:
Thesis (MScEng (Civil Engineering))--University of Stellenbosch, 2010.ENGLISH SUMMARY: It is found that the serviceability limit state often governs the design of slender reinforced concrete members. Slender flexural members often have a percentage tension reinforcement less than 1.0% and an applied bending moment just above the point of first cracking. For such members, the available methods to evaluate the serviceability conditions produce inadequate and unrealistic results. The evaluation of the serviceability of a slender member includes the calculation of the predicted deflection, either by empirical hand-calculation or analysing a finite element model, and the verification using the span-to-effective-depth ratio. The focus of the study is on flat slab structures. It investigates the different deflection prediction methods and the span-to-effective-depth ratio verifications from various design standards. These design standards include the ACI 318 (2002), the SABS 0100-1 (2000), the EC2 (2004) and the BS 8110 (1997). The background to the methods, as well as the parameters which influences the deflection development for lightly reinforced members, are investigated in order to define the limitations of the methods. As a result of the investigation of the deflection calculation methods, an Alternative Approach is suggested and included in the comparisons of the various methods. The deflection prediction methods and the span/effective depth verification procedures are accurately formulated to predict the serviceability behaviour of beams. Additional approaches had to be used to apply these methods to a two-dimensional plane such as that of a flat slab structure. The different deflection prediction methods and the span/effective depth verification methods are calculated and compared to the recorded data of seven experimental flat slab specimens as performed by others. A study by Gilbert and Guo (2005) accurately recorded the flexural behaviour of flat slab specimens under uniformly distributed loads for test periods up to 750 days. The methods to evaluate the serviceability of a slender member were also applied to slab examples designed using South African standards. The study concludes by suggesting a suitable deflection prediction method for different parameter (limitation) categories with which a slender member can comply to. The typical span/effective depth ratio trend is also presented as the percentage tension reinforcement for a slender member changes. It is observed that the empirical hand-calculation methods present more reliable results than those of the finite element models. The empirical hand-calculation methods are accurate depending on the precision to which the slab was constructed relative to the actual slab design. The comparison of the deflection methods with South African case studies identified the role played by construction procedures, material parameters and loading history on slab behaviour.
AFRIKAANSE OPSOMMING: Die diensbaarheidstoestand is in baie gevalle die bepalende faktor vir die ontwerp van slank gewapende beton elemente bepaal. Slank elemente, soos lig bewapende buigbare beton elemente, het gewoonlik ‘n persentasie trekbewapening van minder as 1.0% en ‘n aangewende buigmoment net wat net groter is as die punt waar kraking voorkom. Die metodes beskikbaar om die diensbaarheid van sulke elemente te evalueer gee onvoldoende en onrealistiese resultate. Die evaluering van die elemente in die diensbaarheidstoestand sluit in die bepaling van defleksies deur berekening of die analise van ‘n eindige element model, en die gebruik van die span/effektiewe diepte metode. Die fokus van die studie is platbladstrukture. Die doel van die studie is om die verskillende metodes vir die bereking van defleksie asook die verifikasie volgens span/effektiewe diepte metodes van die verskillende ontwerp standaarde te ondersoek. Die ontwerp standaarde sluit die ACI 318 (2002), SABS 0100-1 (2000), EC2 (2004) en die BS 8110 (1997) in. Die agtergrond van hierdie metodes is ondersoek asook die parameters wat ‘n rol speel, sodat die beperkings van die metodes geidentifiseer kan word. As ‘n gevolg van die ondersoek na die beperkings van die metodes, is ‘n Alternatiewe Benadering voorgestel. Die Alternatiewe Benadering is saam met die metodes van die ontwerpstandaarde gebruik om die verskille tussen die metodes te evalueer. Die defleksievoorspelling en die span/effektiewe diepte verifikasie metodes is korrek geformuleer om die diensbaarheid van balke te evalueer. Ander benaderings was nodig om die diensbaarheid van blad blaaie te toets. Die onderskeie defleksievoorspelling en span/effektiewe diepte metodes is bereken vir sewe eksperimentele plat blaaie soos uitgevoer deur ander navorsers. Gilbert and Guo (2005) het ‘n studie uitgevoer waar die buigingsgedrag van die sewe plat blaaie, met ‘n uniforme verspreide las vir ‘n toetsperiode van tot 750 dae, akkuraat genoteer is. Die metodes om die diensbaarheid van ‘n slank element te toets, was ook op Suid-Afrikaanse blad voorbeelde getoets. Dit was gedoen om die Suid- Afrikaanse ontwerp van ligte bewapende beton elemente te evalueer. Die gevolgetrekkings stel ‘n gepaste defleksie metode vir ‘n slank element vir verskillende beperking kategorië voor. Dit is ook verduidelik hoe die tipiese span/effektiewe diepte verhouding met die persentasie trek bewapening vir ‘n slank element verander. Dit is bevind dat die imperiese handmetodes om defleksies te bereken, meer betroubaar as die eindige element modelle se resultate is. Die imperiese handberekening metodes is akkuraat relatief tot hoe akkuraat die blad konstruksie tot die blad ontwerp voltooi is. ‘n Vergelyking van defleksieberekening met Suid-Afrikaanse gevallestudies het die belangrikheid van konstruksieprosedures, materiallparamteres and belastingsgeskiedenis geïdentifiseer.

Full textAbstract:
The work in this thesis is directed towards the measurement and prediction of the shape of the flow channel in granular solids as they discharge from flat-bottomed silos. It is widely believed that the flow pattern affects the pressure distribution against the walls and so also the stresses in the silo structure. Thus, a reliable means of predicting the shape of the flow channel has important design implications. Kinematic analysis is used as the basis for the theoretical work. The governing partial differential equation contains one unknown empirical parameter: the kinematic parameter. Finite element formulations are developed and implemented to solve for the steady-state vertical velocity field in flowing granular solids for a range of conjectured kinematic parameters. The formulations are applied to the analysis of flow from flat-bottomed silos with planar or axisymmetric geometries. Criteria are proposed to define the boundary between flowing and near-stationary solid. The flexibility of the finite element method allows many original kinematic analyses to be carried out e.g the analysis of silos with more than one outlet; the analysis of planar silos with eccentrically-positioned orifices; the analysis of the effect of a spatially-varying kinematic parameter and the modelling of the top surface displacement are all claimed to be original. Experiments are carried out in a half-cylindrical flat-bottomed silo. A rigid transparent sheet is used to form the front wall. The bisection of the flow in this way allows direct observation of flow mechanics to be made and the shape of the flow channel boundary can also be traced. Two solids are tested: a rough, frictional solid (sand) and a smooth, free-flowing solid (polypropylene pellets).

Full textAbstract:
State-of-the-art solar-thermal flat-plate collectors suffer from a limited potential to decrease production costs for the necessary higher economic benefit of so-lar-thermal systems. Costly metallic materials and corresponding manufactur-ing processes prevent further cost reductions. For that issues, plastic materials can offer a promising approach. The main hurdle for the use of cost-effective plastics lies in the high thermal loads on the collector components — absorber and insulation — which were identified in a field-testing. The necessary overheating protection approaches to lower these thermal loads were investigated in a literature review. A large number of relevant concepts was evaluated related to achievable temperature reduction, influence on solar yield, additional costs and intrinsic safety. There-fore, a mathematical model was developed to determine the solar-thermal col-lector´s behaviour in a solar-thermal system for hot water and space heating. This way, the most promising overheating concepts were simulated and ana-lysed with regard to component temperatures and system performance. Omitting the selective absorber coating and reducing the backside insulation was found to be the most suitable solution for component materials with limited temperature resistance like polypropylene. In the second part of the research, collector design concepts were developed on the basis of the characteristics of plastic material processing. The identified unit costs showed savings of more than 50 % in comparison to stateof- the-art collectors. The analysis regarding temperature loads and annual solar yield by simulation proved the performance of the concepts. The collector costs and the simulation results were used to define the total costs of the solar-thermal sys-tems and to evaluate the economic benefits by means of the collector con-cepts. The benefits were similar to state-of-the-art set-ups. Thus, further adjustments at system level are necessary to lower the total costs. Therefore, the system set-up has to be harmonised with the collector requirements and investigated in detail.

Full textAbstract:
This work presents a study on aeroelastic analyses of composite laminated flat plates subject to large displacements through the coupling of a nonlinear corotational shell finite element (FE) with an unsteady vortex-lattice method (UVLM) formulation. A FE implemented for the analysis of flat plates has been extended to model laminated composites with different lamina orientations. An UVLM formulation that is capable of coupling with this large displacement structural model is implemented. An explicit partitioned method is evaluated for the coupling of both models, using spline functions to interpolate information from the structural operator to the aerodynamic one, inside a Generalized-? time-marching solution. The resulting aeroelastic formulation provides a framework able of performing time marching simulation of structures made of composite material allowing the characterization of their nonlinear behavior and of the limit-cycle oscillation response. Laminated flat plates designed for high flexibility and low flutter speed onset are used as investigation models. To support the numerical studies, test specimens made of carbon fiber were used in experimental modal analysis and wind tunnel aeroelastic tests. Effects of nonlinearities are easily observed in the numerical results, which are promising for expansion of the work and application to the analysis of more refined and complex composite flexible wings.

Thesis (Masters Diploma (Heavy Current)) -- Cape Technikon, 1991Linear induction motors are built for numerous applications. Their robustness, gearfree-link to the load and the fact that speed is not a function of the number of poles (as in round machines) are only a few advantages. As every single phase motor needs some starting aid, so does a linear induction drive. For round machines, capacitors or shaded poles are usually used. A capacitor can be damaged electrically, which is a rare occurrence for shading rings. A useful combination of these advantages is a linear induction motor which is gearless and uses the shaded pole principle as a starting aid. In order to simplify the designing process, a computer program (Fortran) was written. The main objective on the electrical side was to obtain low input power, high power factor and high efficiency. In order to find the performance curves, torque measurements were made. Although the principles of torque measurements are well known the device to measure torque for this machine was not available and had to be constructed.

Resumo: Esta pesquisa qualitativa teve como objetivo obter informações sobre estratégias de estudo de alunos de flauta transversal e, ao final, apontar sugestões para melhorias nesse estudo. Inicialmente, foi feita uma revisão histórica acerca do estudo da flauta transversal para situar as maneiras em que o ensino e aprendizado deste instrumento se desenvolveram. Abordou-se as caraterísticas da relação mestre-aprendiz, tendo como referência o tratado de Quantz, até chegar ao ensino sistematizado por meio da instituição conservatório como escola profissionalizante. A seguir, foi feita uma entrevista estruturada com seis estudantes de flauta de uma instituição de ensino superior (IES) brasileira, buscando extrair informações sobre as práticas de estudo dos alunos e sua formação musical. A partir das entrevistas, com base na análise de conteúdo de Laurence Bardin (2008), foram criadas quatro categorias abordando questões acerca dos modelos propostos pela tradição de ensino conservatorial, priorizando a aquisição de habilidades técnicas e, também, da organização de estratégias aplicadas no estudo diário que beneficiam o aprimoramento da performance. A análise de conteúdo dos relatos coletados apontou que o modelo de ensino tecnicista ainda é adotado como principal escolha entre os sujeitos investigados. As discussões apontam para um estudo que contemple um pensamento mais reflexivo, que possa beneficiar o planejamento de estratégias e adaptá-las às necessidades de cada indivíduo, otimizando assim o tempo e visando a uma prática eficaz
Abstract: This qualitative research aimed to obtain information about study strategies of undergraduate flute students and, at the end, to point to suggestions to improve the practice of the instrument. To begin with, we did an historical review of the study of the flute to situate the ways in which the teaching and learning of the instrument have developed. We have approached the features of the relationship between master-apprentice based on the treaty of Quantz, reaching a systematized study at the conservatory as a technical model . Second, we did a semi-structured interview with a group of six undergraduate flute students of a Brazilian university, searching for information about how they practice the instrument daily, and how they relate their practice with their own musical formation. After the interview, we created four categories approaching issues about the traditional models to learn that prioritize study of technical skills, and also about the organizing strategies applied in daily study to fully improve the performance, based on Laurence Bardin's analysis (2008). The results of analysis' contents of the collected reports shows that the technicist model of education is still adopted as the main choice among the investigated subjects. In the discussion, we point to ways of studying that contemplate a more reflexive thinking that can benefit planning strategies and adapt them to the needs of each individual thus optimizing the time and seeking an effective practice

Mestrado em Ensino de MúsicaTocar um instrumento musical exige grande esforço físico por parte do instrumentista. Devido ao esforço repetitivo, o corpo de um instrumentista pode sofrer alguns problemas físicos provenientes do estudo e da performance do seu instrumento, e consequentemente gerar lesões musculoesqueléticas, dores e desconfortos. Os flautistas não fogem a esta regra. Apesar da relevância, poucos são os estudos que têm abordado as demandas físicas do estudo da flauta. O presente estudo investigou problemas físicos detetados em músicos, com ênfase nos instrumentistas de flauta transversal, e se estes podem ser amenizados ou mesmo tratados com a realização de exercícios de relaxamento antes e após da performance da flauta. É também abordado o caso de tomada de consciência – propriocepção- como benefício para a performance e prática musical.
Playing a musical instrument requires great physical effort from the musician. Duet to repetitive stress, the musician´s body can suffer some physical problems from study and performance of his/her own instrument, and consequently generate musculoskeletal injuries, aches and pains. Flautists are no exception to this rule. Despite its relevance, there are just a few studies that have addressed the physical demands of the flute´s study. This specific study has investigated physical problems detected in musicians, with an emphasis on flute instrumentalists, and if these can be alleviated or even treated with relaxation exercises before and after the performance of the flute. It is also addressed the case of self awareness – proprioception - as a benefit for performance and musical practice.

Carl Nielsen was the greatest Denmark´s composer who lived from 1865 to 1931. The thesis mentions the development of Nielsen´s composition style beginning with his early music and ending with his mature years of composing. All works are compared comprehensively. In his early years, there is a domination of the elements typical for romantic lyricism, but later on, his composition technique becomes influenced by the progressive styles of the 20th century. The thesis is focused on the composer´s late music, because most of his flute works were written during his mature years. The compositions analysed in detail are following: orchestral work Pan and Syrinx, op.49, a piece for flute solo from the incidental music Aladdin, op.34, three pieces from the incidental music Moderen, op.41, Wind Quintet, op.43, Concerto for Flute and Orchestra, six symphonies and Rhapsody Overture: An Imaginary Trip to the Faroe Islands . On one hand, the analysis of each work is accentuated, but on the other hand, the historical events and facts from Nielsen´s life which affected his compositions are pointed out.

Buscou-se nesta pesquisa estudar os princípios criativos (poéticas) que orientam as decisões de flautistas quanto à preparação de peças inéditas de música contemporânea que envolvam técnicas estendidas e notação não-tradicional para flauta transversal, de forma a conceber um conjunto de práticas de interpretação de obras inéditas a partir da leitura da partitura, sem ouvir interpretações anteriores, e a aplicação pedagógica destes princípios. Para acessar como são feitas as tomadas de decisões durante a construção de uma interpretação de música contemporânea, foi realizado um estudo de campo em que três flautistas profissionais que habitualmente estreiam peças de música nova e quatro estudantes de nível superior gravaram em áudio/vídeo o processo de leitura e interpretação de três miniaturas para flauta solo compostas especialmente para esta pesquisa, verbalizando suas tomadas de decisões; uma entrevista após a performance final das peças complementou o levantamento de dados. Partindo dessas verbalizações e com base metodológica na Teoria Fundamentada, criou-se uma categorização dos aspectos levantados, englobados em: leitura preliminar, dimensões básicas e dimensões interpretativas da performance. A filosofia hermenêutica enquanto estudo da interpretação, especialmente Hans-Georg Gadamer e Luigi Pareyson, e mais especificamente o conceito de “verdade” na obra de arte, lançaram luz para a análise dos dados coletados. Considerações sobre o desenvolvimento da autonomia do performer, levando em conta os conceitos de autorregulação e automaiêutica e a análise do estudo de campo, complementam-se para uma proposta pedagógica de abordagem de obras desconhecidas que envolvam técnicas estendidas por meio da leitura de partituras. Entendemos que a inclusão de obras contemporâneas que envolvam novas sonoridades e técnicas estendidas durante a formação dos estudantes é essencial para que o repertório desenvolvido a partir de meados do século XX não seja negligenciado e sua preparação seja mais completa.The aim of this research was to study the creative principles (poetics) that guide flutists’ decisions regarding the preparation of new pieces of contemporary music, which involve extended techniques and non-traditional notation, in order to conceive of a set of practices for interpreting new works from reading the score without listening to previous interpretations, and also the pedagogical application of these principles. To access how decisions are made during the construction of an interpretation of contemporary music, a field study was conducted in which three professional flutists, who usually première pieces of new music, and four undergraduate students recorded, in audio/video, the process of reading and interpretating three miniatures for solo flute composed especially for this research, verbalizing their process of interpretive decisions; an interview after the final performance of the pieces complemented data collection. Methodologically based on Grounded Theory, a categorization of these verbalizations was created and the aspects raised were encompassed in: preliminary reading, basic dimensions and interpretative dimensions of the performance. The hermeneutic philosophy as a study of interpretation, especially Hans-Georg Gadamer and Luigi Pareyson, and particularly the concept of “truth”of the art work, shed light for the analysis of the collected data. Considerations about the development of a performer’s autonomy, taking into account the concepts of self-regulation and auto-maieutics and the analysis of the field study, complement each other in a pedagogical proposal for approaching unknown works that involve extended techniques by means of reading scores only. It is understood that the inclusion of contemporary works that involve new sonorities and extended techniques during the training of students is essential so that repertoire developed from the mid-20th century is not neglected and students’ preparation becomes more comprehensive.
L’obiettivo di questa ricerca è stato quello di studiare i principi creativi (le poetiche) che guidano le decisioni dei flautisti nella preparazione di nuovi brani di musica contemporanea che includono tecniche estese e notazioni non tradizionali, al fine sia di concepire un insieme di pratiche interpretative di opere nuove partendo dalla lettura della partitura, senza ascoltare interpretazioni precedenti, sia di elaborare delle applicazioni di questi principi in ambito didattico-pedagogico. Al fine di indagare come vengono prese le decisioni durante la costruzione di un’interpretazione di musica contemporanea, è stato condotto uno studio sul campo nel quale tre flautisti professionisti che solitamente eseguono in prima assoluta pezzi di nuova musica e quattro studenti universitari hanno registrato, in audio/video, il processo di lettura e interpretazione di miniature per flauto solo composte appositamente per questa ricerca, verbalizzando il loro processo decisionale; un’intervista dopo l’esecuzione finale dei pezzi ha completato la raccolta dati. Sulla base metodologica della Grounded Theory, è stata creata una categorizzazione di queste verbalizzazioni e gli aspetti sollevati sono stati raccolti nelle seguenti categorie: lettura preliminare, dimensioni di base e dimensioni interpretative della performance. La filosofia ermeneutica come studio dell’interpretazione, in particolare le opere di Hans-Georg Gadamer e Luigi Pareyson, e più specificamente il concetto di “verità” dell’opera d’arte, hanno fatto luce sull’analisi dei dati raccolti. Le considerazioni sullo sviluppo dell’autonomia dell’interprete, tenendo conto i concetti di “autoregolazione” e “auto-maieutica” e i risultati dello studio sul campo, si completano in una proposta pedagogica di avvicinamento a opere sconosciute che coinvolgono tecniche estese attraverso la sola lettura delle partiture. Si riconosce che l’inclusione di opere contemporanee che includono nuove sonorità e tecniche estese durante la formazione degli studenti è essenziale sia affinché il repertorio flautistico sviluppato sin dalla metà del XX secolo non sia trascurato sia per una più completa preparazione degli studenti.

Full textAbstract:
The main purpose of this report, is to evaluate feasibility of using The Global Positioning System as an aiding tool for vehicle state estimation based on nonlinear techniques, and to develop a potential solution to the road bank angle problem. Previous work within the CEmACS project, includes development of a general nonlinear observer for lateral and longitudinal velocity, and an augmentation in the form of road-tire friction adaptation. Because the existing solutions have been shown to lack robustness with regards to certain disturbances, such as road grade and road bank angle, it has been stated that the estimation scheme should be upgraded, so that these disturbances can be accounted for. By including GPS velocity or a or a roll rate gyro measurement in the observer feedback loop, the possibility of detecting previously inobservable quantities is gained. In simple terms, evaluation of feasibility corresponds to demonstrating improvements and limitations of new solutions, using relatively crude methods in the test procedures. Problems related to the above mentioned task, are approached by means of signal processing and control theory. Following an intuitive sequence of operations, the report presents GPS theory and results first, as this lays the foundation for all subsequent results. Methods used comprise simple differentiaton, rotational kinematics and discrete filtering. Secondly, theory and results related to nonlinear observers, with focus on GPS aiding, are examined thoroughly. Lyapunov theory, known from control engineering, is used to evaluate stability, while data from simulations and actual vehicle tests is used to show how a new observer scheme can improve existing solutions. Before the most important results are presented, something should be said about their accuracy and significance. It has already been pointed out that the methods used are not based on optimality requirements, and consequently the results are best viewed as indicators of potential, rather than absolute solutions. This is especially true for the GPS velocity calculations, which are based on differentiation of position measurements; generally not a desired approach. In this report, it is firstly shown that GPS position measurements can be used to compute receiver velocity in the body-fixed coordinate frame. While this is a crude approach, resulting in relatively poor signal to noise ratio, it is easily implemented on low-level equipment. It is also shown that it is possible to use these velocities as measurements in a nonlinear observer structure, slightly modified from previous solutions within the CEmACS project. By doing this, accurate estimates of road grade and bank v angle are achieved, so long as these vary slowly enough. Stability of the observer is not proven in the general sense, but it is shown that it can be made stable through realistic assumptions and gain selection. Stability is further demonstrated through the use of data sets from actual vehicle tests. Secondly, a mathematical model of roll dynamics is combined with a roll rate measurement to create the possibility of detecting road bank angle. This is done by the now familiar nonlinear observer approach. Usefulness is demonstrated by simulations, but no stability proof is presented. The main conclusion is that it is feasible to use GPS aiding to account for robustness problems in a vehicle state estimation scheme, and that the inclusion of a roll rate measurement opens up possibilities for cheap bank angle detection. A direct implementation of results presented in the report may not be ideal, but the fact that the system works for a large set of conditions, suggests that it is worthwhile to develop it further. This is especially true when it is assumed that GPS receivers will become an integral part of new vehicles in the near future. Refinements and upgrades can be made in the form of more advanced GPS technology, new parameter estimation techniques and integration with the road-tire friction adaptation scheme.

This report examines the cross sections of silver microresonators subjected to an incident light with different polarization. The microresonators had different geometries with and without broken symmetries. Cross section profiles for different microresonator configurations are interesting for the division of Material Physics, Uppsala University, when designing metamaterials to tune the optical response of the material. The goal is to form an insight of how the optical response can be tuned by choosing different geometries, varying the size and polarization of the incident light. In this project computer simulations in COMSOL were made to simulate the optical response of different microresonators. When the incident light interact with the silver microresonators plasmonic excitations is generated which in turn interacts with the light changing the phase and therefore the optical response. By increasing the radius of the disk silver microresonantors the resonance was found to shift to lower energies. For a geometry with a disk microresonator inside a ring microresonator the Fano resonances were dependent of the radius of the disk microresonator.

Full textAbstract:
Gear rolling is one of the latest techniques being used in gear manufacturing. As compared to traditional gear manufacturing techniques, gear rolling can add benefits like improved surface finish, increased flank strength, increased load capacity and less material usage. After initial research initiatives in USA, Germany and China, efforts are underway to make this technique industrially viable for production of both low and high module gears. There are two methods for gear rolling one uses round tools while other uses flat tools. The current work examines advantages and limitations associated with gear rolling by flat tools. A finite element simulation software has been used to analyze the process and results are compared with actual gear to confirm viability of the process. The results of the simulations validate the previous findings about gear rolling and provide a base for future developments in this field.

Full textAbstract:
In this thesis, studies of flat or pancake type electromagnetic launcher systems are described. The studies involved the development of several numerical models, and are supported throughout by experimental investigation. The models were based on a coaxial filamentary division technique, and the results they provided were compared with those from a commercial electromagnetic finite element modelling package. They were used to investigate some of the many possible launcher structures and power supply arrangements, as part of a wide-ranging parametric study. The aim of this thesis was to gain an insight into the factors that affect the performance of the launchers. Several different techniques were implemented to reduce the computation time. Practical experimentation provided a clear demonstration of the launcher technology, and supplied valuable model validation data. To aid the experimental work new projectile speed and yaw measurement systems were developed, and these were supported by results from a high-speed camera. A novel dual projectile launcher was tested, and was shown to improve the launch efficiency and to operate at higher energies, due to the reduction in drive coil recoil. Projectile deformation was investigated in both solid discs and flat annular projectiles.

Full textAbstract:
The first result of this thesis is a partial result in the direction of Steinberg's Conjecture. Steinberg's Conjecture states that any planar graph without cycles of length four or five is three colorable. Borodin, Glebov, Montassier, and Raspaud showed that planar graphs without cycles of length four, five, or seven are three colorable and Borodin and Glebov showed that planar graphs without five cycles or triangles at distance at most two apart are three colorable. We prove a statement that implies the first of these theorems and is incomparable with the second: that any planar graph with no cycles of length four through six or cycles of length seven with incident triangles distance exactly two apart are three colorable.
The third and fourth chapters of this thesis are concerned with the study of Pfaffian orientations. A theorem proved by William McCuaig and, independently, Neil Robertson, Paul Seymour, and Robin Thomas provides a good characterization for whether or not a bipartite graph has a Pfaffian orientation as well as a polynomial time algorithm for that problem. We reprove this characterization and provide a new algorithm for this problem. In Chapter 3, we generalize a preliminary result needed to reprove this theorem. Specifically, we show that any internally 4-connected, non-planar bipartite graph contains a subdivision of K3,3 in which each path has odd length. In Chapter 4, we make use of this result to provide a much shorter proof using elementary methods of this characterization.
In the fourth and fifth chapters we investigate flat embeddings. A piecewise-linear embedding of a graph in 3-space is flat if every cycle of the graph bounds a disk disjoint from the rest of the graph. We provide a structural theorem for flat embeddings that indicates how to build them from small pieces in Chapter 5. In Chapter 6, we present a class of flat graphs that are highly non-planar in the sense that, for any fixed k, there are an infinite number of members of the class such that deleting k vertices leaves the graph non-planar.
