Um dos maiores problemas relacionados ao quotidiano das médias e grandes cidades é o trânsito e por meio dele percebemos os conflitos de circulação urbana e se os meios de transportes fluem de forma satisfatória. Segundo Vasconcellos (1999), transporte público é um conjunto de elementos físicos que se distribui espacialmente, atendendo a população que dele depende. Localizada no oeste do Estado de São Paulo a cidade de Presidente Prudente enfrenta, hoje, um grave problema no tocante à circulação e à eficiência dos meios de transportes públicos, sendo esse oneroso para a população que o usufrui. Em termos proporcionais a tarifa por quilômetro rodado é muito elevada, em comparação às grandes cidades do Estado de São Paulo e do Brasil. Sendo o transporte público parte essencial de uma cidade, o seu funcionamento deve estar de acordo com o crescimento da mesma e atender qualitativamente e quantitativamente seus usuários, propondo um adequado uso do espaço urbano. Diante de tal realidade, o projeto tem, por objetivo, fomentar a proposta de implantação de terminal urbano de transporte público, baseado no redesenho viário da principal centralidade da cidade...

No início do trabalho, quando comecei a desenvolver a idéia de estudar a sonoridade musical e misturá-la com a Arquitetura, eu pensava mais em utilizar as características fluidas do som, essa facilidade que ele tem de se movimentar livremente no ar e, por isso, se dispersar por entre as pessoas muito facilmente, chegando até elas a todo o momento, sem que nenhum empecilho físico o impeça de atingi-las. Então, sabendo da alta sensibilidade que os humanos têm ao som, devido à sua própria natureza estrutural vibratória, eu partiria para uma análise mais particular de como a Música poderia influenciar as pessoas em seu dia-a-dia, de como as pessoas reagem a certos sons. E então utilizar isso dentro da Arquitetura, seja na sua composição, seja na interação e vivência usuário-espaço. Porém, com o andamento dos estudos e com o desenvolvimento do projeto, ocorreu que não poderia deixar certos aspectos de lado, como por exemplo, estudar técnicas que usamos para compor ambas as Artes, como as estruturações utilizadas, elementos rítmicos, harmônicos, proporcionais, estudar o próprio som e a matéria, fundamentais na Música e na Arquitetura, assim como a questão da temporalidade e da espacialidade. Ainda assim, não via o trabalho como completo. Por isso optei por acrescentar mais uma parte a ele, complementar a todo o desenvolvimento já elaborado e às questões já estudadas, porém de fundamental importância para a conclusão do projeto. Será o capítulo intitulado Musicalidade Aplicada, o qual ainda é subdividido em Música & Arquitetura, onde apresento alguns projetos exemplares, nos quais os autores de alguma forma se utilizaram de música na composição e/ou execução de suas obras; e Música & Urbanidade, onde finalmente apresento a sonoridade musical como um meio de mudança da perspectiva humana, mudança de posicionamento e olhar do homem para o próprio homem e do meu olhar para a arquitetura

With the growing world energy demand mainly from developing countries like Brazil, Russia, India and China, the search for efficient sources of energy becomes a challenge for the coming years. Among the most widely used alternative sources, biomass is the one that grows in a more pronounced way. This study will assess the real possibility of having it as a heat source in an Organic Rankine Cycle, which employ heat transfer fluids as working fluids instead of water. From a regional data collection in agricultural production and their potential rice production and the resulting husk was defined as more appropriate. The availability of husks together with an amount of eucalyptus wood, provided by a company in the region on a monthly basis, were analyzed, and the low participation of the wood was discarded by the thermal contribution of little significance. Based on this, it was established the calorific value of fuel for thermodynamic calculations and the cycle to be used. It was then carried out the choice of working fluid from the literature and their availability in the library of software used for the simulations, the Engineering Equation Solver - ESS. The fluid most appropriate for the burning of biomass, Octamethyltrisiloxane (OMTS), was not included in the software and so the R227ea and R134a were selected. After the initial parameters modeling definition, as condensing temperature, efficiency and live steam conditions, the simulations were performed, and only the R227ea remained within the feasible thermodynamic and technological ranges. With this fluid the turbine power output was 265.7 [kW] for a scenario of 24 hours/day burning, 800.3 [kW] to biomass burning for 8 hours/day and 2134 [kW] for burning only 3 hours/day. The thermal efficiency of the cycle remained in the range of 6%, and for plants operating with the most... (Complete Abstract click eletronic access below)

The steady increase in the price of oil and its derivatives, carbon credits, the concern with the environment combined with the precipitation of rain water and lack of water resources that Brazil has suffered in 2014 caused a migration of participation sources of energy in the Brazilian energy matrix. The hydropower sector suffered big drop at 2013 and is suffering so far, contributing thus to the generation and cogeneration of thermal energy using renewable energy sources such as: sugarcane bagasse, wood chips, rice husks, among others. The selling price of the electricity market reached the level of R$ 807, 00 MWh in January 2014 (Source: ANEEL), heating the Brazilian thermoelectric sector. Although thermoelectric use in bulk water as vaporizing fluid to produce electricity and use in various processes, water reuse plans have become an important factor in these industries. The increased use of biomass has been the bagasse which is allied to the sugarcane sector, strong market in Brazil, and consists basically use the rest of sugar cane, sugarcane industries that would play out. The sugar and ethanol industry is very unstable and only lasts for 6-8 months a year, and the remaining time in the period known as between crop that corresponds to the planting and harvesting of sugarcane and then enter the period of vintage which is the constant cane harvesting and crushing it. This instability of the market and the thermoelectric idle period leads the thermoelectric industries to seek other sources of renewable energy, such as wood chips (pine, Eucalyptus, Orange), rice husk, sorghum among others, to not be dependent on alcohol sector. The present work aims to study the use of wood chips as an alternative biomass for burning a fuel that essentially uses bagasse, the thermoelectric in question consists of two boilers that produce together 350 t / h ...

In Brazil there are many cases of cities that suffer from flooding. It often destroys much of the structure of the city, and isolates many families. Relying on emergency measures for these cases and similar cases is of utmost importance. This paper proposes the development of a project of a timber bridge that can be used in emergency situations such as occurs in situations of floods and especially on side roads. It is considered one type of structural bridge which has, among other characteristics, an easy transportation and assembly of the elements. The development is carried out, at this early stage of the project, only about the verification and sizing of structural elements of the superstructure of the bridge. For this purpose, it relies on computer programs, and fundamentally on PCFrame Visual Taco. The first allows you to model the structure and determine the efforts of calculating the elements, and the second one assists at the scaling and the verifications in accordance with the Brazilian technical standards for timber bridges. The wood used in the project comes from the tree Eucalyptus saligna, which is easy to acquaint and manipulate and comes from the region Vale do Paraíba. The bridge in this case of application should have the characteristics mentioned below: short execution time, simplicity of structure and an assembly of a relatively low cost

The aim of this research study was to evaluate the structural behaviour of the wood and concrete composite system for bridge decks with emphasis on the metal shear connectors. Experimental tests were performed on composite specimens and wood and concrete beams with a metallic connector system in an X position, using CS100900-type screws. All specimens and beams were submitted to static loads until failure in order to obtain the strength and stiffness of the connection system. The experimental results for the stiffness of the beams were compared with the analytical results obtained through the Mohler model, presenting good equivalence for service loads. The experimental results obtained demonstrate that the most significant damage in composite systems occurred in the connectors' areas.
