Such paradigm introduces images in the classroom and is not exclusively worried about making the studio s works. There is a preparation in order to analyze and understand images before producing a poetical response. The objective of this research is to put the Triangular Proposal into practice, declared by Ana Mae Barbosa, aiming at the development of abilities for the appreciation, contextualization and elaboration of poetical proposals for the high school pupils. The presented theory is based on the Triangular Boarding which has three components: reading (Critical and Aesthetic), contextualizing (History of the Art) and working in studio (Artistic Education). The complete knowledge of this theory happens when such components are carried out simultaneously. The methodology of this research is qualitative, descriptive and exploratory, using the Research-action as theoretical basis. In the present research, the pupils, based on the reading, analysis and contextualization of the works of the Pinacoteca do Estado de Sao Paulo s collection have produced poetical responses through plastic arts, reinterpreting and giving new understandings of the original works. / Esta dissertação é o produto de uma pesquisa sobre metodologia de ensino de Artes no Ensino Médio e apresenta um novo paradigma para as aulas da referida disciplina. Por um lado, introduz a imagem no cotidiano escolar e, por outro, não está preocupada unicamente no fazer dos trabalhos de ateliê. Há toda uma preparação em analisar e entender imagens antes de produzir uma resposta poética. O objetivo desta pesquisa é aplicar a Proposta Triangular, enunciada por Ana Mae Barbosa, visando o desenvolvimento de habilidades para a apreciação, contextualização e elaboração de propostas poéticas pelos alunos do Ensino Médio. O quadro teórico apresentado tem como referência a Abordagem Triangular que está fundamentada em três componentes: ler (Crítica e Estética), contextualizar (História da Arte) e fazer (Educação Artística). Estes, quando atendidos simultaneamente, propiciam o pleno conhecimento na área. A metodologia de pesquisa utilizada é qualitativa, descritiva e exploratória, utilizando como base teórica a pesquisa-ação. Nela, partindo da leitura, análise e contextualização de obras do acervo da Pinacoteca do Estado de São Paulo, os alunos produziram respostas poéticas em artes plásticas, reinterpretando e dando novas leituras às obras originais.

It aims to used the methodology called Triangular , set out by Anna Mae Barbosa, intending to develop the skills for the appreciation, contextualization and elaboration of poetic proposals of high school students. The research was justified in using images in the classroom and, consequently, there was a preparation to analyze and understand them before making an artistic production. The images are of rural workers and were chosen because it is an issue rarely studied in the field of Arts and little known by students. The proposal was that they meet the artists and their works, the socio-cultural context and history of the time, discussing their life and experiences expressed by the artists, thus creating a new perspective on the current critical condition and really enjoy the importance of the Arts. The methodology used was the qualitative research, which is theoretically based on the Research-Action. In this, the students produced responses in poetic art, by reading, analyzing and contextualizing painting of Candido Portinari and pictures of Sebastião Salgado, reinterpreting and creating new readings of works. The discussions held in this research are related to works that have social meaning, those dealing with the analysis of workers at two specific moments by artists who have different techniques to address the issue. In one part, Portinari paints the frescoes with the theme of workers, on the other, Salgado, using photo focuses on the dimension of those employees who interact with Brazil social. / Esta dissertação teve por base uma pesquisa sobre metodologia de ensino em Artes Visuais aplicada no Ensino Médio, na Escola Pública Estadual Professora Ziporam Rubinstein, situada na Zona Leste da cidade de São Paulo. O objetivo foi aplicar a Metodologia Triangular, enunciada por Ana Mae Barbosa, visando o desenvolvimento de habilidades para a apreciação, contextualização e elaboração de propostas poéticas pelos alunos do Ensino Médio. A pesquisa justifica-se pela utilização de imagens em sala de aula, havendo, portanto, uma preparação em analisar e entender estas imagens antes do fazer artístico. As imagens analisadas são de trabalhadores rurais e foram escolhidas por ser uma temática pouco abordada na área e pouco conhecida pelos alunos. A proposta foi fazer com que os mesmos conhecessem os artistas e suas obras, o contexto sócio-cultural e histórico da época de criação, dialogando com as vivências e experiências expressas pelos autores, criando assim, uma nova perspectiva crítica sobre a atual condição e realidade na importância do fruir a Arte. A metodologia de pesquisa utilizada foi qualitativa, tendo como base teórica a pesquisa-ação. Nela, os alunos produziram respostas poéticas em artes plásticas a partir da leitura, análise e contextualização da pintura de Candido Portinari e da fotografia de Sebastião Salgado, reinterpretando-as e criando novas possibilidades de significações para elas. As discussões que permearam o trabalho tiveram como referência as obras de sentido social, ou seja, aquelas que tratam da análise dos trabalhadores em dois momentos específicos e feitas por artistas com diferentes técnicas de abordar o assunto. Se de um lado Portinari pinta os afrescos com a temática dos trabalhadores, por outro, Salgado, usando a fotografia põe em evidência a dimensão dessa mesma categoria de pessoas no momento em que interagem na questão social do Brasil.

Neutron transport in hexagonal reactor cores modeled by trigonal-geometry diffusion and simplified P3 nodal methods

Duerigen, Susan January 2013 (has links)
The superior advantage of a nodal method for reactor cores with hexagonal fuel assemblies discretized as cells consisting of equilateral triangles is its mesh refinement capability. In this thesis, a diffusion and a simplified P3 (or SP3) neutron transport nodal method are developed based on trigonal geometry. Both models are implemented in the reactor dynamics code DYN3D. As yet, no other well-established nodal core analysis code comprises an SP3 transport theory model based on trigonal meshes. The development of two methods based on different neutron transport approximations but using identical underlying spatial trigonal discretization allows a profound comparative analysis of both methods with regard to their mathematical derivations, nodal expansion approaches, solution procedures, and their physical performance. The developed nodal approaches can be regarded as a hybrid NEM/AFEN form. They are based on the transverse-integration procedure, which renders them computationally efficient, and they use a combination of polynomial and exponential functions to represent the neutron flux moments of the SP3 and diffusion equations, which guarantees high accuracy. The SP3 equations are derived in within-group form thus being of diffusion type. On this basis, the conventional diffusion solver structure can be retained also for the solution of the SP3 transport problem. The verification analysis provides proof of the methodological reliability of both trigonal DYN3D models. By means of diverse hexagonal academic benchmark and realistic detailed-geometry full-transport-theory problems, the superiority of the SP3 transport over the diffusion model is demonstrated in cases with pronounced anisotropy effects, which is, e.g., highly relevant to the modeling of fuel assemblies comprising absorber material.

An appeal for the consideration of the mimetic theory of René Girard

Stewart, Craig 04 June 2013 (has links)
The Mimetic Theory (MT) of René Girard promises a new landscape for the humanities. In this paper I will outline MT, giving a brief overview of the terrain and how the theory works, defend MT against criticisms made against it, and argue that MT ought to be evaluated by a wider academic audience. / Thesis (Master, Philosophy) -- Queen's University, 2013-06-03 14:15:30.176

Mathematical modelling of shallow water flows with application to Moreton Bay, Brisbane

Bailey, Clare L. January 2010 (has links)
A finite volume, shock-capturing scheme is used to solve the shallow water equations on unstructured triangular meshes. The conditions are characterised by: slow flow velocities (up to 1m/s), long time scale (around 10 days), and large domains (50-100km across). Systematic verification is carried out by comparing numerical with analytical results, and by comparing parameter variation in the numerical scheme with perturbation analysis, and good agreement is found. It is the first time a shock-capturing scheme has been applied to slow flows in Moreton Bay. The scheme is used to simulate transport of a pollutant in Moreton Bay, to the east of the city of Brisbane, Australia. Tidal effects are simulated using a sinusoidal time-dependent boundary condition. An advection equation is solved to model the path of a contaminant that is released in the bay, and the effect of tide and wind on the contaminant is studied. Calibration is done by comparing numerical results with measurements made at a study site in Moreton Bay. It is found that variation in the wind speed and bed friction coefficients changes the solution in the way predicted by the asymptotics. These results vary according to the shape of the bathymetry of the domain: in shallower areas, flow is more subject to shear and hence changes in wind speed or bed friction had a greater effect in adding energy to the system. The results also show that the time-dependent boundary condition reproduces the tidal effects that are found on the Queensland coast, i.e. semi-diurnal with amplitude of about 1 metre, to a reasonable degree. It is also found that the simulated path of a pollutant agrees with field measurements. The computer model means different wind speeds and directions can be tested which allows management decisions to be made about which conditions have the least damaging effect on the area.

Nesta época, muitas propostas renovadoras foram introduzidas no campo da educação. Também foi observado o que as professoras pensam sobre o ensino da Arte hoje. A pesquisa se caracteriza por ser um estudo de caso, com abordagem qualitativa. A pesquisa foi conduzida da seguinte maneira: aplicou-se um questionário e uma entrevista semi-estruturada a nove professoras que trabalhavam nessa escola. Também foram analisados documentos da época. Os dados foram coletados em 2010 e analisados segundo a Análise de Conteúdo proposta por Bardin (1977). Foi estabelecido um diálogo teórico-metodológico com os autores que investigam o Ensino da Arte e a Formação de Professores, entre eles, Ana Mae Barbosa (1984), Maria F. de Resende e Fusari e Maria Heloísa C. de T. Ferraz (1993), Anamelia Bueno Buoro (1996) e Paulo Freire (1996). Os dados obtidos revelaram que as práticas pedagógicas ora se aproximavam da Proposta Triangular da Arte, no que se referia ao fazer artístico em sala de aula, ora se distanciavam, por não contemplarem a apreciação e a contextualização. A pesquisa propõe que uma formação continuada para professoras polivalentes por meio de cursos, oficinas e encontros bimestrais com professores graduados em artes possa contribuir para o desenvolvimento de uma educação mais significativa e menos fragmentada, que auxilie na superação das dificuldades dessas professoras no ensino de artes.

Mass loading and Stokes number effects in steady and unsteady particle-laden jets.

Foreman, Richard J. January 2008 (has links)
In single phase, steady, turbulent axisymmetric jets, the time-averaged velocity field can be characterised by the decay in centreline velocity and increased spread with increasing distance from the jet orifice. In a two-phase or ‘particle-laden’ jet, the particles will modulate the jet turbulence and exchange momentum with the gas phase. Consequently, these effects reduce both the centreline velocity decay and spreading rates with respect to the single-phase jet. Empirical exponential scaling factors were found by previous authors to describe the reduced centreline decay and spreading rates well for low Stokes numbers. In this thesis, power-law scaling factors are found to scale well a wide range of centreline velocity decay and spreading rate data published over the past 40 years, for a wide range of Stokes numbers. The power-law scaling is composed of three different regimes. For low Stokes numbers St₀ ≲20, it is found that the gas phase centreline velocity, u₀/uc collapses if plotted as a function of x/D(1 + Ø₀)⁻¹, and the velocity profile half widths r₁/ ₂ collapse if plotted as a function of x/D(1+Ø₀)⁻¹. Here, u₀ is the exit velocity, Ø₀ is the exit mass loading, x is the axial coordinate and D is the pipe diameter. For intermediate Stokes numbers, u₀/uc collapses if plotted as a function of x/D(1 + Ø₀)⁻¹ and r₁/ ₂ collapses if plotted as a function of x/D(1 + Ø₀)⁻¹/². For high Stokes numbers St₀ ≳ 200, u₀/uc collapses if plotted as a function of x/D(1 + Ø₀)⁻¹/² and the half width is approximately independent of Ø₀. In addition to the velocity of the gas phase, other aspects of particle- laden jets are found to be amenable to scaling by power-law functions. It is found that reported solid phase mass flux data scales similarly to gas phase measurements. Limited solid phase concentration and entrainment measurements reported in the literature are also found to scale by power-law functions. Whereas that limited data was obtained from the literature, measurements of the distribution of particles in particle-laden jets were conducted to further assess the validity of the scaling regimes to the solid phase. A planar light scattering technique is conducted to measure the distribution of particles in an axisymmetric jet and their subsequent scaling (or lack thereof) are reported for a variation in Ø₀, Stokes number and gas phase jet exit density. For Stokes numbers based on the pipe friction velocity St* ₀ ∼ 1, half widths of particle distributions were found to scale with x/D(1+Ø₀)⁻¹/² . The apparent centreline concentration was found to be independent of Ø₀ at this same St* ₀ . For Stokes numbers based on the pipe friction velocity St*₀ < 1, half widths are independent of Ø₀. The effect of the other parameters, i.e. Stokes number and density ratio, on centreline distributions and half widths are also investigated. Measurements of particle distributions, delivered via an annular channel, in a triangular oscillating jet (OJ) flow are also reported for a variation in momentum ratio, the ratio of OJ momentum to channel momentum and mass loading. The results of the variation in momentum ratio on particle distributions are compared with an existing precessing jet (PJ) study. It is the aim of this study to determine the experimental conditions for which the OJ nozzle is superior to the PJ nozzle. The use of an OJ nozzle is preferable at an industrial scale by virtue of its lower driving pressure compared with a PJ nozzle. It is found that particle distributions in a PJ flow spread at a greater rate with increasing momentum ratio compared with the spread of particles in an OJ flow. However, at momentum ratios approximately less than unity, the absolute spread from an OJ is greater. This also corresponds to nozzle driving pressure less than approximately 10kPA. For an increase in mass loading, the spread of particle distribution in the OJ decreases and recirculation increases. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1337352 / Thesis (M.Eng.Sc.) -- University of Adelaide, School of Mechanical Engineering, 2008

Computational Complexity of Finite Field Multiplication / Beräkningskomplexitet för multiplikation i ändliga kroppar

Quttineh, Nils-Hassan January 2003 (has links)
<p>The subject for this thesis is to find a basis which minimizes the number of bit operations involved in a finite field multiplication. The number of bases of a finite field increases quickly with the extension degree, and it is therefore important to find efficient search algorithms. Only fields of characteristic two are considered. </p><p>A complexity measure is introduced, in order to compare bases. Different methods and algorithms are tried out, limiting the search in order to explore larger fields. The concept of equivalent bases is introduced. </p><p>A comparison is also made between the Polynomial, Normal and Triangular Bases, referred to as known bases, as they are commonly used in implementations. Tables of the best found known bases for all fields up to GF(2^24) is presented. </p><p>A list of the best found bases for all fields up to GF(2^25) is also given.</p>

Periulnar Injuries Associated with Distal Radius Fractures

Scheer, Johan January 2011 (has links)
Residual dysfunction after a fracture of the distal radius is most often mild but may give rise to significant impairment especially in the younger active population. The symptoms often manifest around the distal ulna when loading the hand or rotating the forearm. In this region are found articular and soft tissue connections running from the distal ulna to the distal radius as well as to the ulnar side of the carpus. The aims of this thesis were to investigate the effects of distal radius fractures on the structures about the distal ulna and to what extent malunion and ulnar soft tissue lesions affect function. Both patients and cadaver specimens were used in the five different studies. In a retrospective study of 17 malunited distal radius fractures supination impairment improved significantly by correction of the skeletal malunion. This highlights the importance of distal radioulnar joint congruity for forearm rotation in a subset of cases. The pathomechanisms of injury to the triangular fibrocartilage complex (TFCC) were studied. In a cadaveric distal radius fracture model different restraining properties and injury patterns were investigated. Similar patterns of injury were then observed in 20 patients with a displaced distal radius fracture. It was found that a TFCC injury can be expected with dorsal displacement of the distal radius fragment of 32o or more from the anatomically correct position. The distribution of a TFCC injury apparently differs depending on the size of an associated ulnar styloid fracture. In cases of an intact ulnar styloid or a concomitant tip fracture (Type 1) the first stage of injury seems to be extensor carpi ulnaris subsheath separation from the distal ulna and the dorsal radioulnar ligament. Thereafter follows a disruption of the deep insertions into the fovea of the ulna starting from the palmar and extending dorsally and radially. An extensive injury can be detected with a novel non-invasive test called the ‘bald ulnar head test’, which is performed under anaesthesia. Diagnosis of an acute TFCC injury is difficult using non-invasive methods. In a prospective study of 48 patients, CT scanning to detect pathologic subluxation was found to be of little use in both acute and chronic cases, and is therefore not endorsed on this indication. A radioulnar stress test, which in previous studies has correlated well to a deep TFCC injury, was found to be highly reliable but not to correspond with significant disability in self-administered questionnaires of functional outcome two years or more after injury. This indicates that the subset of patients possibly benefiting from acute repair must be identified by other means.
