Os materiais analisados foram vidros nos sistema soda-cálcio e boro-silicato. Os espelhos foram comparados em relação a dilatação térmica e a sua rigidez elástica, tendo como principal objetivo avaliar qual vidro deformaria menos sua superfície mantendo sua qualidade óptica em relação a variação da tmmperatura e do seu próprio peso. Para tanto, a análise foi realizada através dos resultados captados pelo interferômetro de Bath, montado no Observatório Didático de Astronomia Lionel José Andriatto, da Faculdade de Ciências, UNESP, Bauru. Como amostras para o trabalho, foram utilizados espelhos primários côncavos de telescópios Newtonianos construídos com os vidros analisados. As medidas foram inspiradas nas condições que os espelhos sofrem durante o seu uso, ambientes com temperatura variável e efeitos causados pela gravidade quando os espelhos estão na posição vertical. Ainda para testar a rigidez elástica dos vidros, os espelhos foram apoiados apenas pelas bordas. Os parâmetros utilizados para verificar o desempenho da superfície dos espelhos, foram deformados na curvatura, somatória das deformações na frente de onda e fator Strehl. Utilizando as franjas de interforometrias que foram associadas aos polinômios de Zernike por análise computacional, foi possível realizar o levantamento dos defeitos na superfície com precisão de nanômetros. Através dos dados obtidos no trabalho foi possível confirmar o desempenho superior do espelho feito com vidro de boro-silicato, esse material se apresentou mais estável em todas as medidas realizadas, sofrendo deformações na superfície menores que o vidro soda-cálcico / This work aims to compare the performance of two types of glasses, which are the most used in the manufacture of medium sized concave mirrors (up to 25 cm of diameter). The investigated materials were soda-lime and borosilicate glasses. The mirrors were compared concerning their thermal expansion and their elastic rigidity, and the main goal was to find out which glass would have a less deformed surface, main goal was to find out which glass would have a less deformed surface, maintaining the optical quality, under temperature variation and the mirror weight itself. In order to accomplish that, an analysis was carried out based on data collected by the Bath interferometer, built in the Didactic Astronomy Observatory Lionel José Andriatto. As samples for this work, it was used concave primary mirrors of Newtonian telescopes built with these glasses. The measurements were based on conditions that mirrors are exposed during their regular use, such as variable temperature environments and gravity effects when the mirrors are kept upright. Besides, to test the rigidity, the glass mirrors were held only by the edges. To check the performance, the used parameters were deformation in curvature, the sum of the wavefront deformations and Strehl factor. Interometer fringes were associated with Zernikes polynomials by computational analyses, making possible a survey of defects on the surface with nanometer accuracy. Using data obtained in this study, it was possible to confirm the superior performance of the mirror built with borosilicate glass, which was the most stable sample in all the measurements, presenting less surface deformations when compared with the sodalime glass

During a forty-five year period the architecture of Henry Edmund Goodridge progressed from Regency Greek Revival, through late Georgian Picturesque towards Victorian Eclecticism. The aim of this study is to show how through such development Goodridge produced a style that fused historical architectural forms with modern advances in technology, in order to create an architecture that was appropriate to the age he inhabited. This work will investigate Goodridge’s built and unrealised projects at each stage of his career, creating a full list of his works, including newly discovered material (Appendix I), and discuss what they illustrate about his architectural aims and ideas. Such analysis will reveal that, rather than the malleable local architect of common perception, Goodridge was a talented and innovative professional who was continuously at the forefront of national developments in aesthetics and architectural style.

This thesis is an exploration of architecture as an active participant in human life, not just as a stage. When architecture is considered a participant it contributes to the improvement of our quality of life as well as aiding  the healing process when we fall ill. As more people are diagnosed with anxiety and sleep disorders, the thesis considered questions of how the places in which we carry out our day-to-day lives improve the prognosis and, further, can architecture be used as a powerful tool for healing? It is possible that our disconnection from nature is partially responsible for our disrupted sleep patterns and misplaced anxieties. Perhaps natural elements and rhythms are too absent in our daily urban lives. But as more of us move into cities and our urban centers become denser, designers must find clever ways to help city owls reset their circadian rhythm. Architecture can help reestablish that bond with nature. This thesis explores an architecture of healing by proposing a program and design that follows the day and night circadian rhythm of our bodies, which in turn follow the sun and other natural phenomena. Located in a tricky triangular site in one of the busiest nighttime neighborhoods of Washington DC, a wellness center and sleep clinic would allow city dwellers to find a peaceful oasis for healing. In parallel, this thesis is also a study of collage as a design tool, as well as designing from details and the human scale. / Master of Architecture

The thesis is about an urban bathhouse in Suzhou, China that explores the relationship of the time honored traditions with modern customs and building techniques. Traditional bath house in memory is always crowded, confined, dim and toneless. The project seeks a new possibility for a modern bath house by studying the structural order and light quality, to make the bath house not only a place for body hygiene, but also a place for mind relaxation and rejuvenation. / Master of Architecture
