The work of my MFA thesis exhibition comes directly out of the physical processes that constitute my studio practice. It is work that embodies the labour of my hands and the decisions that guided them in their struggle with unfamiliar materials. Drawing inspiration from subjects as diverse as physics and fiction to create a sculptural arrangement, the work is intended to engage with its audience in an active way through acoustic appropriation and physical presence. As an artist, I set up an environment to be explored, establishing boundaries and also possibilities.

No Brasil, a quase totalidade dos edifícios habitacionais empregam revestimentos de argamassa em suas fachadas. Este revestimento vem passando por alterações significativas ao longo do tempo, dentre as quais se destaca a substituição do lançamento manual de argamassas pela projeção, por meio de equipamentos mecânicos, em especial a aplicação mecanizada contínua, com bombas helicoidais. Acredita-se que este sistema, por possibilitar o fluxo contínuo na etapa de aplicação e promover a diminuição da interferência das habilidades dos operários durante a execução, permite alcançar maior produtividade e melhorar a qualidade dos revestimentos, mas as diferentes técnicas de execução empregadas para a produção dos revestimentos de argamassa aplicados com projeção mecânica contínua ainda não foram avaliadas sistemicamente quanto à sua interferência no comportamento destes revestimentos. Sendo assim, o objetivo deste trabalho é avaliar a influência de algumas variáveis empregadas na execução dos revestimentos de fachada de argamassa aplicados com projeção mecânica contínua, no seu comportamento, mais especificamente na adesão inicial, fissuração e aderência. Estas variáveis foram selecionadas através de um levantamento bibliográfico e aplicadas a um estudo experimental, no qual foram executados vinte e sete painéis de revestimento, para verificação da influência das variáveis no comportamento destes revestimentos. Ao final, foram apresentados e avaliados os resultados obtidos, por meio de análises qualitativas (adesão inicial e fissuração) e quantitativas (no caso de resistência de aderência). Os resultados obtidos permitiram concluir que, apesar de haver um acréscimo significativo da resistência de aderência à tração com a projeção mecânica contínua da argamassa, em comparação à aplicação manual, o teor de água das argamassas, associado à condição de umidade do substrato e ao tempo entre demãos, e as técnicas de acabamento da superfície do revestimento podem influenciar significativamente o comportamento dos revestimentos, aumentando ou diminuindo a resistência de aderência. / In Brazil, almost all residential buildings make use of exterior cement-based rendering. This rendering has been going through significant changes over time, among which the substitution of hand application of the mortar by mechanical methods of application, in particular the wet spraying method using rotor type machines. It is believed that this system, by allowing the continuous flow in the application step and reducing user skill interference, promotes greater productivity and helps to increase the quality of the rendering, but the different execution techniques employed in its production still havent been systematically evaluated regarding their interference in the renderings behavior. Hence, the objective of this study is to evaluate the influence of some variables related to the execution techniques of exterior cement-based rendering applied with the wet spraying method using rotor type machines on their behavior, more specifically on initial bonding, cracking and adhesion. These variables were selected through bibliographic data gathering, and then applied to an experimental study on which twenty seven rendering panels were executed for the verification of the influence of the variables on their behavior. The results were presented and evaluated by qualitative (in the case of initial bond and cracking) and quantitative analyses (in the case of adhesion). The results obtained allowed to conclude that, despite a significant increase in adhesion with the mechanical projection of the mortar compared to manual application, the water content of the mortar, associated with substrate moisture condition and time between coatings, as well as the techniques of surface finishing of the coating may affect the rendering quality by increasing or decreasing the adhesion strengths.

Related to that, it can be said that it is about respect with nature during economy and society development of a certain region. If so, with the growth of civil construction and industrialization of today’s world, each time growth atmospheric emissions, solids and liquids, harm the environment and causing damage to the greenhouse effect caused mainly by increasing the concentration of carbon dioxide in the atmosphere. Thinking about the impact caused by those emissions was created the tool of Life Cycle Assessment, which is capable to measure all emissions involved in services and materials life cycle. Using this tool in civil construction, specifically in the service of internal mortars, this paper aimed in making a comparison between two materials emissions of CO2, which are alternatives able to make the internal mortar, the regular mortar prepared in site and industrialized mortar. Going through the process of obtaining data along industry and sellers, and making a data collect about mortar consumption inside two constructions in the city of Goiânia, was possible do set the comparison, getting the conclusion that despite being highly industrialized, the industrialized mortar shows a better performance with regard to CO2 emissions, ie, emits a lower amount of gas to achieve the same service. Part of the explanation for that is the logistic adopted for using industrialized mortar, which requests a change in the using process. It is also possible to realize that the better performance toward regular mortar is due the high consumption of electricity needed to use this, making the Brazilian energy matrix responsible for a large amount of carbon dioxide emissions in the atmosphere. / O desenvolvimento sustentável vem sendo uma realidade altamente discutida no contexto mundial. Relacionado a ele, pode ser citado o respeito com a natureza durante o desenvolvimento da economia e da sociedade de uma determinada região. Sendo assim, com o crescimento da construção civil e da própria industrialização do mundo atual, cada vez mais aumenta a quantidade de emissões atmosféricas, sólidas e líquidas, agredindo o meio ambiente e causando danos como o efeito estufa, causado principalmente pelo aumento da concentração do dióxido de carbono na atmosfera. Pensando no impacto causado por tais emissões, foi criada a ferramenta da Avaliação do Ciclo de Vida, que é capaz de mensurar todas as emissões envolvidas no ciclo de vida de materiais e serviços. Utilizando essa ferramenta na construção civil, mais especificamente no serviço de revestimento interno em argamassa, esse trabalho teve como objetivo realizar uma comparação de emissão de CO2 entre duas alternativas de materiais que pudessem ser utilizados para o serviço, a argamassa convencional rodada em obra e a argamassa industrializada. Passando pelo processo de obtenção de dados junto as indústrias e fornecedores, e realizando uma coleta de dados de consumo de argamassa dentro de duas obras na cidade de Goiânia, foi possível delimitar tal comparação, chegando à conclusão de que a apesar de ser altamente industrializada, a argamassa industrializada apresenta um melhor rendimento quanto às emissões de CO2, ou seja, emite uma menor quantidade do gás para realização do mesmo serviço. Parte da explicação para isso é a logística adotada para utilização da argamassa industrializada, que exige uma mudança nos processos de utilização. Também é possível perceber que tal desempenho em relação à argamassa convencional se deve ao alto consumo de energia elétrica necessário para a utilização dessa, fazendo com que a matriz energética brasileira seja responsável por grande quantidade de emissão de dióxido de carbono na atmosfera.

Modelling and rendering natural phenomena, such as rain, is an important aspect of creating a realistic driving simulator. Rain is a crucial issue when driving in the real world as it for instance obstructs the driver’s vision. The difficulty is to implement it in a visually appealing way while simultaneously making it look realistic and keeping the computational cost low. In this report, a GPGPU (general-purpose computing on graphical processing units) based approach is presented where the final product is a rain simulation rendered onto a 2D texture, which can then be applied to a surface. The simulated raindrops interact with gravity, wind, a windshield wiper as well as with each other, and are then used to distort the background behind them in a convincing manner. The simulation takes into account multiple physical properties of raindrops and is shown to be suitable to run in real-time. The result is presented in form of a visual demonstration. In conclusion, even though the final simulation is still in its first iteration, it clearly highlights what can be accomplished by utilizing the GPU and the benefits of using a texture-based approach. The appropriate simulation approach will however always depend on the characteristics of the problem and the limitations of the hardware.

Web page loading time is one of the critical challenges on the Internet. Thistopic attracts more researchers as it largely reflects the user satisfaction.A web page resources typically consists of Hyper Text Markup Language(HTML), Cascading Style-Sheet (CSS), JavaScript (JS), media files, etc.As the complexity of the web page increases, the size of files fetched fromserver also increases which causes delay in transmitting, loading, parsing andrendering the web page.The web page is not rendered until HTML, CSS and JS files are loadedand parsed. Not all such files are needed to be rendered for the first page.Optimizing and loading only critical les required for the first page, can considerablyreduce time taken to load the web page. After the first page isrendered, the rest of the files can be loaded and executed. In this thesis,we focus on improving the time taken for First Meaningful Paint(FMP) ofwebsite by loading the critical files initially. We used Design Science Research(DSR) methodology and created a PhantomJS application, to identifyand segregate used and unused CSS for the first meaningful paint of the webpage. We also analyzed script files to load only critical files required forFMP and the rest later. We evaluated our experiment by studying a case onAxis Communications AB and measured its website's performance to find ifour experiment reduced FMP time. It showed improvement in time takenfor FMP from 1284ms to 372.6ms. Based on the results, we suggest to webdevelopers to separate and load the files required for FMP and load the restof the files needed for the website later, so that the first page is renderedquickly.

The film industry utilizes more and more computer generated visual effects and the visual effects industry and the surrounding community is continuously growing. It unlocks possibilities for the creative director that before was hard to achieve. And as technology advances, it does not only push the limit of the quality and complexity of the visual effects, but also allows ordinary people and amateurs with a tight budget to create stunning visuals as well.The report will cover render passes and the importance of a linear workflow. The report will determine common key material assets a compositor needs from rendering in order to have full control in post-production. Practical examples made with Maya and Nuke will be used. / <p>Validerat; 20120802 (anonymous)</p>

From optimal thermal insulation and suitable base coat was conducted proposal of final version of new ETICS.

Using slow camera movement in 20 minutes in five video scenes of completely CGI-rendered environment called Area of Universal Latency, I am mapping space-time of the zone which is located in the north-western Slovakia. Minimalistic narration of the autonomous single-channel video projection is confronting subjectivism with universality of the Anthropocene, vanitas and spirituality with the belief of consumerism in infinite accumulation and simulacra of virtuality with the absolute truth. The story of this video-poem is communicated through virtual environment, composed sounds and natural noises. This thesis is presenting a fragment of my attempt to record the morphology of the specific place through which, as the title of the video states, I am indicating the state of reality and its consequences yet not describing it explicitly.
