The rheo-optical concept is claimed once both flow-birefringence and rheological character of polystyrene are probed during the process. To accomplish this task, three pressure gauges are flush-mounted along the channel of the slit-die to determine the pressure drop of the flowing polymer. Moreover, borosilicate optical windows are adjusted into two different sites in-between the pressure transducers. Thus, one could assess the rheo-optical responses at two different entrance lengths. When studying polystyrene melt, the flow birefringence measurements showed different molecular orientation levels along the channel axial direction, being slightly lower in the second section next to the slit die outlet. The viscosity values measured in-process were lower at the second section of the slit-die. In addition, they were well below that calculated from rotational rheometry. By following the time-temperature superposition, the melt temperatures assessed in real time were found to be considerably higher than those chosen as the set points. This was ascribed to viscous dissipation generated mainly at the extrusion barrel boundaries. The real time assessment of polymer melt by the use of thermocouples agreed with estimated ones from reduced variables method. On the other hand, temperature increments were found to be a function of the mass flow. This is not taken into account on bench techniques due to isothermal flow assumption. Rheo-optical measurements carried out at both steady state and transient mass flow procedure showed that polystyrene behaves as a thermo-rheological material and, apparently, the stress optical rule holds for the processing conditions investigated given the independence of the flow-birefringence versus stress curve slopes with feed rate and temperature set-points. / Este trabalho apresenta o desenvolvimento de uma matriz de fenda instrumentada para avaliar a influência das condições termomecânicas do processo de extrusão dupla rosca no fluxo dos polímeros. A birrefringência de fluxo e as características reológicas do polímero são calculadas a partir dos dados obtidos no exato momento do processamento. Três transdutores de pressão foram montados ao longo do canal da matriz para permitir a determinação das quedas de pressão geradas pelo fluxo polimérico. Janelas ópticas de borossilicato foram ajustadas à matriz de fenda em dois sítios distintos. Ao se estudar o fluxo de poliestireno por birrefringência de fluxo foi possível verificar níveis de orientação distintos ao longo do canal, sendo maior para a primeira seção próxima a entrada da matriz. A caracterização reológica em tempo real sugere que as viscosidades nas duas seções analisadas são diferentes. Estas estavam bem abaixo dos valores experimentais obtidos por reometria rotacional. As estimativas de temperatura pelo princípio da superposição tempo-temperatura indicam que esta disparidade é função da liberação de energia interna na forma de calor gerada pelo histórico termomecânico no processo de extrusão, em função da dissipação viscosa. A medida da temperatura do fundido em tempo real pelo uso de termopares na região interna da matriz e em sua saída corroboram os dados estimados pelo método de redução de variáveis. No entanto, o aumento de temperatura é função da vazão mássica trabalhada, mostrando ainda mais característica térmica não uniforme do processo de extrusão. Os dados reo-ópticos obtidos no estado estacionário e no transiente de vazão mássica demonstram que o poliestireno usado é um material termoreologicamente simples e que, aparentemente, a regra do coeficiente de tensão óptica é válida nas condições trabalhadas, dado a independência da inclinação da curva de birrefringência de fluxo versus tensão na parede com a vazão e com a temperatura.

The images are obtained by a system composed of a stereo camera coupled to a computer via a capture board. The OpenCV library is used for computer vision operations and processing images involved. The algorithms discussed are an overall method of search for matching blocks with the Sum of the Absolute Value of the difference (Sum of Absolute Differences - SAD), a global technique based on cutting energy graph cuts, and a so-called matching technique semi -global. The criteria for analysis are processing time, the consumption of heap memory and the mean absolute error of disparity maps generated.

The proposed technique has the potential of attenuating several problems faced by the constant depth algorithm, making it possible to reduce the number of errors or the number of comparations needed to get equivalent results. Several experiments were performed to demonstrate the method efficiency, including comparison with the traditional plain correlation technique, where the multi-resolution matching with variable depth, proposed here, generated better results with a smaller processing time / Para acelerar o rnatching em sistemas de vis?o est?reo ? proposta uma abordagem multi-resolu??o, coarse-to-fine, variando a profundidade do nivel inicial para cada pixel da imagem.

The legal concept of formal burden of proof of public prosecutor has been discussed for more than 17 years of legislative work on the new Criminal Procedure Code and an increased attention was also paid to it before by the legal science, at the same time with the enforcement of adversary elements of court proceedings. The legal concept in question was established and developed as part of the Anglo-Saxon type of criminal proceedings where trial is based on a dispute between the parties. This involves the exclusive procedural responsibility of public prosecutor to clarify the facts relevant to the indictment filed. Although it is possible to give a brief description of the legal concept in question in a single sentence, its enactment would affect the overall nature of the proceedings before the court and would also be reflected in other stages of the criminal proceedings. The aim of the dissertation was to analyse the prerequisites and consequences of the enactment of the formal burden of proof of public prosecutor in the Czech criminal proceedings. Given the origin of the legal concept, the crucial question was whether its adoption would necessarily constitute a total departure from the legal principles which the existing Criminal Procedure Code is based on or whether it is possible and appropriate...

In this perspective, starting from theoretical-methodological issues that include not only the dialogues that the images interlock, but, especially, their temporal and mnemic links, it was also aimed to establish a relation between the work that celebrated the gaucho and the ga?cho in the twentieth century with those that preceded it. Thus combining the nascent image of the eighteenth and nineteenth centuries with that which was consecrated in the twentieth century, it was intended to define the diverse and multiple threads that, intertwined, produced a wide and complex network of meanings around the image of the gaucho and the ga?cho. These same threads, woven by times and memories, by yearnings and desires, besides particularizing the image of the man from the pampa, also reveals their uses and their functions. / La presente tesis doctoral, tiene como objetivo principal analizar la forma con lo cual la imagen gaucha y del ga?cho fue construida y consagrada en la pintura argentina, uruguaya y brasile?a del siglo XX, en especial en la pintura de Ces?reo Bernaldo De Quir?s (1879-1968), Pedro Figari (1861-1938) y Pedro Weing?rtner (1853-1929). En ese sentido, y partiendo de las cuestiones te?rico metodol?gicos que perciben no solamente los di?logos que las im?genes se traban entre s?, pero, sobre todo, en sus encadenamientos temporales y mn?micos, se ha objetivado, tambi?n, establecer una relaci?n entre la obra que ha celebrado el gaucho y el ga?cho en el siglo XX junto aquellas que los precedieron. As?, conjugando la imagen de los siglos XVIII y XIX, se pretendi?, pues, definir los diversos y m?ltiples hilos que entrelazados, produjeron una amplia y compleja red de significados acerca de la imagen del gaucho y del ga?cho. Esos mismos hilos, tramados por el tiempo y por memorias, por anhelos y deseos, aparte particularizar la imagen del hombre del pampa, igualmente revela sus usos y funciones. / A presente tese de doutorado tem como objetivo central analisar a forma com a qual a imagem do gaucho e do ga?cho foi constru?da e consagrada na pintura argentina, uruguaia e brasileira do s?culo XX, especialmente na pintura de Ces?reo Bernaldo de Quir?s (1879- 1968), Pedro Figari (1861-1938) e Pedro Weing?rtner (1853-1929). Nesse sentido, partindo de quest?es te?rico-metodol?gicas que percebem n?o apenas os di?logos que as imagens travam entre si, mas, sobretudo, seus encadeamentos temporais e mn?micos, objetivou-se, tamb?m, estabelecer uma rela??o entre a obra que celebrou o gaucho e o ga?cho no s?culo XX junto das que lhe antecederam.

The mathematical formalism begins with the representation of motion in Euclidean space. After that, the projection of the images is performed in an ideal camera perspective using homogeneous coordinates. This results in the intrinsic and extrinsic parameters, which are part of the camera calibration. From that, stereo vision is used to obtain three-dimensional position of objects that are captured in the images from two cameras. Thus, depths of various objects are obtained to reconstruct their positions. The validation of the proposed algorithms are made through an experiment built for this purpose. This experiment uses two cameras with semi-parallel views to the center. In the center of the environment there is a gimbal platform, which performs a uniform motion. Above, there is a plan with three white dots, simulating the objects position. This motion captures two images, which are processed by the proposed algorithm. The validation consists in making a comparison between the orientation planes of the gimbal servomotors and reconstruction objects. / Este trabalho trata da estima??o da posi??o tridimensional de m?ltiplos objetos a partir de imagens capturadas em um ambiente de vis?o est?reo. O formalismo matem?tico utilizado no projeto do sistema de vis?o est?reo inicia-se com a representa??o de cen?rio, levando todo o ambiente para um espa?o euclidiano, tamb?m chamado de representa??o em tr?s dimens?es. Depois de representar o espa?o euclidiano no sistema de vis?o est?reo, leva-se esse formalismo ?s proje??es das imagens numa perspectiva da c?mera ideal em coordenadas homog?neas, das quais se obt?m a c?mera com par?metros intr?nsecos e extr?nsecos. A partir disso, utilizam-se os conceitos de vis?o est?reo e triangulariza??o entre as c?meras para calcular a profundidade dos diversos objetos presentes no cen?rio. Assim, a reconstru??o tridimensional da imagem ? obtida. A valida??o dos algoritmos propostos ? feita atrav?s de um experimento constru?do especialmente para o sistema de vis?o est?reo, em que foram colocadas duas c?meras com vistas semiparalelas em um ambiente, sendo tamb?m adicionada uma plataforma do tipo gimbal movimentando-se em tr?s dimens?es. Acima dessa, ? colocado um plano com tr?s pontos (marcadores), os quais simulam o movimento de tr?s objetos.

Māori education has grown out of a long and varied history of Māori engagement with Western forms of schooling. Full immersion Māori learning environments such as kura kaupapa Māori emerged from a background of colonial Mission schools, Native Schools, and evolving assimilation and integration educational policies. It is the subsequent loss of language, continual Māori school underachievement and Māori struggles for indigenous self-determination that have provided the conditions in which the development of Kaupapa Māori otherwise known as Māori medium education has taken place. Māori medium education has emerged in varying forms and differing levels of Māori language immersion, although the principles and philosophies of these environments remain particularly Māori orientated. Kaupapa Māori education is largely built upon whānau aspirations and is set within a Māori framework of learning and Māori language teaching. In addition to full immersion Māori schools there are other classroom settings that offer varied levels of Māori language instruction. Some of these classrooms have been established in English medium schools, creating a bilingual context. While full immersion schools focus on the breadth of all things Māori, bilingual schools may have a slightly different focus. May, Hill and Tiakiwai (2006 p.1) in their review of Bilingual Education in Aotearoa explain it as an area of instruction where school subjects are taught in two languages (Māori and English) and students become fluent orators and writers in both. Little is understood about the dynamics of partial immersion programmes and the contribution these settings make to Māori language and cultural knowledge acquisition and to wider self-determination aspirations of Māori. Drawing from the contributed insights of teaching staff, whānau and other stakeholders linked to partial immersion education, this research considers these settings to better understand the relationship between language acquisition and cultural knowledge attainment. A synergy of Kaupapa Māori theory with a qualitative interpretivist approach has guided the research process. The rationale for the research was to strengthen cultural knowledge and cultural aspirations which made it appropriate to use Kaupapa Māori principles as a foundation of which to develop the research. As research is currently limited in this respect a more extensive understanding of the teaching and learning programmes within a partial immersion classroom may be paramount to their continuation and success. Key findings emerged from the participant interviews and clear characteristics of these environments developed: Whānau (family), te reo Māori me ōna tikanga (Māori language and cultural customs) Māori values, and Māori pedagogies. The participants talked about many features particular to partial immersion education that linked to these four themes. The themes were further analysed to find key positive outcomes of these settings. A strong sense of pride in identity, particularly Māori identity and Māori succeeding as Māori were the two key positive outcomes that emerged from the participant data.
