No 1o. deles, fazemos uma análise da peça "Os Sete Gatinhos", de Nelson Rodrigues. Procuramos aí compreender alguns elementos básicos da dramaturgia do autor, como a questão do trágico e do cômico delineando as situações dramáticas e as personagens. Nos 2o. e 3o. capítulos, pretendemos uma análise da questão do erotismo e da morte, temas recorrentes na dramaturgia do autor, bem como uma investigação sobre a presença da doença marcando o elemento corpóreo, fisiológico, tão explorada por Nelson. Algumas idéias do filósofo Georges Bataille orientaram-nos nesse sentido. O 4o. capítulo procura dar conta de uma contextualização do universo rodrigueano no seu ambiente social, resgatando sua historicidade. Processos literários pertinentes a essa dramaturgia também são aqui abordados. No momento seguinte, um paralelo entre o teatro de Nelson e as experiências de vanguarda da dramaturgia universal, principalmente o que se convencionou chamar por "Teatro do Absurdo". E finalmente, no último capítulo, um esforço no sentido de compreender o universo dramático de Nelson Rodrigues valorizando-a a partir de critérios mais restritos ao literário. / Abstract: Not informed. / Mestrado / Teoria e Critica Literaria / Mestre em Letras

This dissertation explores the themes of collaboration and creativity in the relationship between arranger Nelson Riddle and vocalists Frank Sinatra and Ella Fitzgerald. It examines the balance between structure and freedom as well as the specific musical results that emerge from collaboration between an arranger and vocalists who are considered among the greatest in their fields. An examination of their interactions, musical scores, and performances, reveals that the constraints that are present in a collaborative effort can lead the artists to find a shared process to make a creative, unified product.

The master thesis is looking into the estimation of yield curve using two ap- proaches. The first one is searching for parametric model which is able to describe the behavior of yield curve well and estimate its parameters. The parametric mo- dels used in the thesis are derived from the class of models introduced by Nelson and Siegel. The second approach is nonparametric estimation of yield curves using spline smoothing and kernel smoothing. All used methods are then compared on real observed data and their suitability for various tasks and concrete available observations is considered. 1

Grading within a single school was studied by comparing the grades with the policy of grading recommended by the high school, and the relationship between the grades and two tests administered by the school. Six hundred fifty-five graduates from the 1964, 1965 and 1966 graduating classes made up the sample. The grades used were those received during their three years in high school. The tests were the Henmon-Nelson Test of Mental Ability administered in the tenth grade and the American College Test which was taken in the twelfth grade. The Pearson r Correlation Coefficient was used to make the correlations. The number of A and B grades given in all subject areas were beyond that recommended by the school policy. A t test showed the differences in grading between required subjects and nonacademic elective subjects in the lower 25 percent of each graduating class to be significant at the .01 percent level. In the upper 25 percent the differences were not significant. The required subjects area grades correlated highest with scores from both tests.

This thesis explores the role of water in urban landscape architectural design and identifies strategies that will conserve and optimise the use of water in the built environment. This is done through selecting a site in Pretoria at the intersection of the Apies River channel and Nelson Mandela drive and designing an Urban Water Centre that explores; exposes and celebrates water in the urban context. The design creates opportunities for kids from nearby schools, students from TUT, residents from the area, pedestrians and tourists to interact on a physical and emotional level with water. Educating people about water conservation is an important aspect of the project and raising awareness is the first step. The design addresses the city-wide need for green public open space and provides opportunities for urbanites to connect with water and the Apies River. This connection is established through the facilitation of significant encounters with water. These include physical contact play with water, creating interest and anticipation around rain events and through translating some of the associated attributes of water into a solid surface. The design approach is influenced by studying the Sustainable Sites Initiative’s ecosystem service approach. Green Star SA is investigated for a possible application to landscape architecture. The findings from the Sustainable Sites Initiative are enhanced by General Systems Theory and then used to generate systems that supports the desired experiences. The first and largest system lifts some of the base flow from the Apies River channel with a waterwheel, where after it is purified in a constructed wetland and a chlorine-free disinfecting process. The clean water is then displayed in a play pond that partially drains through a gravity driven vortex generator. The vortex generator aerates and cools down the water while adding movement; sound and a sense of the passage of time to the human experience. From the vortex, water flows into a constructed pebble lined stream that children can play in and experience stream ecology. The pebbles and vegetation refers back to the Apies River before it was lined with concrete. From the stream the water rejoins the channel. The second on site water system addresses rainwater. The design creates anticipation and curiosity associated with rain events. Rainwater from one of the on site buildings are harvested and displayed in a rain-meter garden. A first-flush system intercepts the first dirty water where after it drizzles down a rain-curtain into a rain-meter system. The rain-meters are large bullet resistant glass tank-like containers, calibrated to show how many millimetres of rain have fallen during the shower. A rain-sensor drains the water into a temporary wetland and lets in percolate into the underground storage tank. The third on site water system treats grey water from buildings through a stepped constructed wetland and displays the cleaned water in a jubilant motion activated display at one of the pedestrian entrances. Water from the rain-meter system; the grey water system and harvested surface runoff all contributes towards meeting the water needs of irrigation and buildings. Other eco-system service strategies identified in the study are applied in the design. These include the protection of on site biomass along with the introduction of region appropriate planting; design for- and use of waste reducing materials and the integration of on site systems to enrich the experience.

Extended plasticity mechanisms (EPM) allow a metal to undergo extended plastic deformation without failure. These mechanisms are responsible for the extended plastic deformation characteristic of hot working processes. In this thesis it is shown that electron backscatter diffraction (EBSD) is capable of detecting EPM artifacts in the final microstructure of AISI 304L stainless steel (304L). Results also indicate that dislocation cells form in hot worked AISI 304L stainless steel. Additionally, in this study EBSD data collection and analysis is used with a design of experiments approach to model the presence of EPM artifacts in the final microstructure of friction stir welded 304L. Texture analysis of the welded material reveals a dominant shear deformation texture and a lack of the rotated cube texture. The shear deformation texture is characteristic of dynamic recovery (DRV) and continuous dynamic recrystallization (CDRX), while the rotated cube texture is characteristic of discontinuous dynamic recrystallization (DDRX). The texture analysis results indicate that dynamic recovery (DRV) and continuous dynamic recrystallization (CDRX) play a role in the final microstructure of the welded material, while DDRX does not. Design of experiments was used to find the relationships between the fraction of cell boundaries and spindle speed, travel speed, location in the stir zone, and tool temperature. The regression analyses reported that predicted fraction of cell boundaries were relatively high (approximately 0.70 or more) and changed by less that 20% in the stir zone and 10% in the TMAZ. The relatively high predictions indicate that in FSW 304L DRV dominates and limited CDRX occurs. The small changes in predictions across the experimental space indicate that the effects, while statistically significant, are not practically significant. Finally, an alternate tool temperature basis was developed, which provides a valid method for selecting welds which should have constant tool temperature.

Full scale lateral load tests were performed on four piles located at various distances behind MSE walls. Three of the four test piles were production piles used to support bridges, and the other pile a production pile used as part of the bridge abutment. The objective of the testing was to determine the effect of spacing from the wall on the lateral resistance of the piles and on the force resisted by the MSE reinforcement. Lateral load-displacement curves were developed for pile at various spacing and with various reinforcement ratio (reinforcement length, L divided by wall height, H). The force in the reinforcement was measured using strain gauges. Lateral load analyses were performed to determine the minimum spacing required to eliminate any effect of the wall on the pile resistance (p-multiplier of 1) and the reduction in soil resistance at closer spacings (p-multiplier less than 1). With the addition of the data fro Price (2012) tentative curves have been developed showing p-multiplier vs. normalized spacing behind wall for a length to height ratio of 1.6, 1.2, and 1.1. The data suggest that with a L/H ratio of 1.6, a p-multiplier of 1 can be used when the normalized distance from the back face of the MSE wall to the center of the pile is at least 3.8 pile diameters. When the L/H ratio decreases to 1.2 and 1.1 a p-multiplier of 1 can be used when the pile is at least 4.5 and 5.2 pile diameters behind the wall respectively. For smaller spacings, the p-multipliers decreased essentially linearly with normalized distance from the wall. A plot showing the increased load in the reinforcement as a function of distance from the pile has been developed. The data in the plot is normalized to the maximum lateral load and to the spacing from the wall to the pile. The best fit curve is capped at a normalized tensile force of approximately 0.12. The data show that the increase in tensile force on the reinforcement when a lateral load is applied to the piles decreases exponentially as the normalized distance from the pile increases. The plot is limited to the conditions tested, i.e. for the reinforcement in the upper 3 ft. of the wall with L/H values at 1.2.

As the world strives towards finding alternative sources of power generation, photovoltaic generation has become an increasingly prevalent alternative energy source on power systems world-wide. This paper studies the effects that incorporating photovoltaic generation has on the existing power systems and their power system protection schemes. Along with the addition of this emerging alternative energy source comes the volatility of PV power generation as cloud-cover produces erratic variations in solar irradiance and PV power production. Such variations in PV power may lead to unfavorable operating conditions and power system failures. The issues addressed in this paper include a study of inverter harmonic levels for variations in DC voltage and power, and a study of power system protection failures caused by cloud-induced PV power variations. Such issues are addressed so as to provide a better understanding of the effects that cloud-induced PV power generation variability has on power systems and its protection schemes.
