Through the vantage point of institutions of higher learning, Utah's distinction as a politically conservative state dominated by the Church of Jesus Christ of Latter-day Saints is examined during the Vietnam War era. The three universities in the study-Brigham Young University, University of Utah, and Utah State University- are the three oldest and most populous universities in the state. This thesis concentrates on these three institutions and less on the politics of the state at the time. Studies showed that the universities, to varying degrees, exhibited antiwar sentiment Still, the campuses were less active in opposing the war, drawing only a very small percentage of students to demonstrations. Brigham Young University's President, Ernest L. Wilkinson (1951-1971), vigorously guarded against signs of antiwar activity. He was involved in the 1966 spy ring, which organized students for surveillance of supposedly liberal faculty. Students who appeared to be antiwar were also scrutinized. Despite the negative sanctions on such students, a minority of pupils did oppose the war and Wilkinson's tactics. The University of Utah produced the highest number of protesters, largely because of its more diverse and urban population. Many of the demonstrators at the U of U continued as activists in the Salt Lake Valley into the 1990s. Utah State University echoed the U of U, but to a lesser extent. Still, underground newspapers and an organized antiwar political party showed that USU also had a movement against the war. The administrations of the two schools figure into the text less powerfully than BYU's Wilkinson because they failed to become as involved in the debate. Oral interviews dominate this thesis. Subjects were chosen according to their involvement in particular events or movements. Student newspapers and underground newspapers were also utilized. This thesis attempted to recreate a tumultuous and turbulent time in American history. Utah's unique cultural slant showed that the Beehive State could not isolate itself from international events but also responded in its own way.

Gauge fields can emerge in the equation of motion for the optically addressed ultracold atoms. To this end, spatially dependent dark states are necessary for the internal states of the atoms. A tripod level scheme yields two degenerate dark states which can leads to either an Abelian U(1) U(1) gauge field or a non-Abelian SU(2) gauge field. Using a suitable laser configuration, we obtain a uniform U(1) U(1) magnetic field which causes the atoms organize themselves in Landau levels. The strength of the effective magnetic field depends on the relative intensity of the lasers beams at the atomic cloud. We estimate the degeneracy of the energy levels for an atomic gas formed by atoms of 87Rb. In addition, we establish the experimental conditions to reach the lowest Landau level regime. In the zero-temperature limit, we realize the emergence of magnetic oscillations in the atomic energy and its derivative as function of the inverse of the effective magnetic field (de Haas van Alphen effect). The period of the de Haas van Alphen oscillation allow us to determine area of the Fermi circle for the atomic gas via an Onsager-like relation. We also show that detuning the a laser from the two-photon resonance we generate a parabolic scalar potential that laterally confines the atoms. As a consequence, the Landau levels degeneracy is removed, since the energy spectrum depends explicitly on the transverse atomic momentum. We show that the Landau levels presents a reminiscent degeneracy when the boundaries conditions are considered. The residual degeneracy occurs when different energy levels overlap. We map the residual degeneracy points as a function of the effective magnetic field. Finally, we present an experimental scheme for observing the spin Hall effect for ultracold atoms in a tripod configuration. / Nesta tese, propomos um arranjo experimental para o estudo da quantização de Landau e efeitos associados em um gás atômico ultrafrio bidimensional. Campos de calibre podem surgir na equação de movimento para átomos ultrafrios oticamente vestidos. Para que isto ocorra, estados escuros espacialmente dependentes são necessários a partir dos estados internos dos átomos. Átomos numa configuração de níveis de energia do tipo tripod produzem dois estados escuros degenerados, que podem levar a campos de calibre Abelianos U(1) U(1) ou não-Abelianos SU(2). Utilizando uma configuração adequada de lasers, mostramos que é possível se produzir um campo magnético sintético uniforme U(1) U(1) que atua nos átomos neutros fazendo-os se organizarem em níveis de Landau. A intensidade do campo efetivo depende da intensidade relativa dos feixes de luz na nuvem atômica. Estimamos a degenerescência dos níveis de energia para um gás atômico formado por átomos de 87Rb e estabelecemos as condições experimentais para que seja atingido o regime em que todos os átomos populam unicamente o nível de Landau menos energético. Considerando o limite de temperatura nula, verificamos o surgimento de oscilações magnéticas na energia e em sua derivada como uma função do inverso do campo magnético efetivo (efeito de Haas van Alphen). O período da oscilação magnética nos permite determinar a área do círculo de Fermi para o gás atômico através de uma expressão similar a de Onsager para sistemas eletrônicos. Mostramos também que dessintonizando um dos lasers em relação à ressonância de dois fótons geramos um potencial escalar parabólico que faz com os átomos sejam lateralmente confinados. Isto resulta na remoção da degenerescência dos níveis de Landau, uma vez que a energia depende explicitamente do momento atômico transverso. Demonstramos que, aplicando condições periódicas de contorno ao sistema, temos o surgimento de uma degenerescência residual. A degenerescência remanescente ocorre quando diferentes níveis de energia se superpõem. Mapeamos os pontos de degenerescência como uma função do campo magnético efetivo. Por fim, apresentamos um esquema experimental para a observação do efeito spin Hall para átomos ultrafrios em uma configuração tripod.

For manufacturers in the wood industry, an important way to make the production more effective is to automate the process of detecting defects and different attributes on boards. One important attribute on most boards is heartwood and sapwood. This thesis project was conducted at the company MiCROTEC and aims to investigate methods to classify heartwood and sapwood on boards. The dataset used in this project consisted of oak boards. In order to increase the amount of information retrieved from the boards, hyperspectral imaging was used instead of conventional RGB cameras. Based on this data, deep learning models in the form of U-Net and U-within-U-Net architecture as well as different spectral dimensionality reduction methods were developed to segment boards in heartwood and sapwood. The performance of these deep learning models was compared to PLS-DA and SVM. PLS-DA has already been used at MiCROTEC and has been used in this work for comparison as a baseline model.   The result of the thesis work showed that a deep learning approach could increase the F1-Score from 0.730 for the baseline classifier PLS-DA to an F1-Score of 0.918, and that the different spectral reduction methods only had a small impact on the result. The increase in F1-score was mainly due to an increase in precision, since the PLS-DA had a similar recall as the deep learning models.

Abstract in English, Xhosa and Venda / Open educational resources (OER) is a new innovation coined to bridge the educational divide by way of providing free quality learning resources. Consequently, this study explored the perception of the faculty members of the Namibian open and distance learning institutions on the use of OER as a pedagogical approach. This study was prompted by the presumption that if ODL institutions adopt open educational resources to replace costly textbooks, an increased number of the Namibian population could access education in the equitable manner. The study focused on faculty members from the three public ODL institutions in Namibia, namely, the Namibian College of Open Learning (NAMCOL), University of Namibia (UNAM)-Centre for Open, Distance and eLearning (CODeL) and Namibian University of Science and Technology (NUST)-Centre of Open and Lifelong Learning (COLL). The following integrated theories were adopted to underpin this study: Transformative Learning Theory, Heutagogy Learning Theory, Cognitive Learning Theory and Social Learning Theory, Constructivism Learning Theory, Connectivism Theory and the Diffusion of Innovations Theory. The theories were compared to the findings to assess their applicability. This is a qualitative case underpinned by an interpretivist paradigm. Data were collected through interviews, non-participant observations and document analysis, and analysed through the inductive approach. The results of this study showed inconsistency between the perception of the faculty members and the use of OER within the ODL institutions in Namibia. Although the faculty members displayed positive attitudes towards the use of OER, very little has been achieved in the use of OER within the institutions for the benefit of the Namibian ODL students. The study identified challenges that impede the adoption of OER at institutional level, such as lack of institutional policies, lack of awareness, technological factors, as well as management support. The study further crafted strategies to address challenges, including the OER design based on the Diffusion of Innovation Model. The study advanced recommendations for consideration by the institutions and the faculty members as well as suggestions for future research. The knowledge contribution made by this PhD is the proposed OER design for adoption by the ODL institutions to facilitate the use of OER by faculty members. / Ubuchule bokufunda ekuthiwa yiOpen Educational Resources (OER) licebo elitsha lokunikezela simahla ngemithombo yokufunda esemgangathweni, nelenzelwe ukukhawulelana nobunzima bokushiyashiyana emfundweni.
