1. Evaluation of Global Heating Reduction Potential with the Replacement of Electricity Supplied by the Local Concessionaire Via Solar Renewable Source.
Abstract The objective of this paper is to evaluate, through the 100-year Life Cycle Analysis, Global Warming Potential (GWP) and Global Temperature Increasing Potential (GTP) impact categories. It is proposed scenario of replacement of the energy matrix for the supply of electricity by Solar Photovoltaic, adopting as consumption base the facilities of Supe

2. Wheel-surface model parameters estimation: sand humidity influence on traction effort of all-terrain unmanned vehicle
Abstract The aim of the paper is to present the experimental results for material model of the sand, case of wet and dry probe. Since traction and side forces derivation methodology and tire-round interaction models for on-road vehicles are widely described, there is a lack of methods for off-road vehicles. The methodology, presented in this work, includes t

3. A New Buffer in Impact Reduction for Aerospace Applications
Abstract The aim of this paper is to introduce a new buffering mechanism in impact reduction during assembly process of two space vehicles. Probe-cone mechanism, due to its computational easiness, is employed to study impact interaction between multibody systems. The proposed buffer with a compact structure includes a probe equipped with axial and torsional

4. Acoustical performance of porous absorber made from recycled rubber and polyurethane resin
This paper reports an investigation of a new kind of material and its acoustical performance. The main component of this porous absorber is the ground tyre rubber (GTR) with different particle sizes, from the shredding of tyres of heavy vehicles, mixed with different proportion of polyurethane resin. Acoustical properties were assessed according to ISO 10534

5. Medição do aporte atmosférico dos elementos-traço nos municípios de Campinas e Paulínia com auxílio da espécie vegetal Tillanásia usneoides (L.) / Measurement of atmospheric supply of trace elements in Campinas and Paulínia with support of vegetal specie Tillandsia usneoides (L.)
The epiphytic bromeliad Tillandsia usneoides (L.) was used as biomonitor of the atmosphere at seven sites along a transect of the municipalities of Campinas and Paulinia. The selected sites are located near highways, industries and avenues, as well as in places farther away from human activities. The samples of were introduced by about two months during five

6. Dynamic response analysis of single-span guideway caused by high speed maglev train
High speed maglev is one of the most important reformations in the ground transportation systems because of its no physical contact nature. This paper intends to study the dynamic response of the single-span guideway induced by moving maglev train. The dynamic model of the maglev train-guideway system is established. In this model, a maglev train consists of

8. Identifying dependability requirements for space software systems
Abstract: Computer systems are increasingly used in space, whether in launch vehicles, satellites, ground support and payload systems. Software applications used in these systems have become more complex, mainly due to the high number of features to be met, thus contributing to a greater probability of hazards related to software faults. Therefore, it is fun

9. ESTUDO DE TRAFEGABILIDADE APLICADO A VEÍCULOS DE RODA EM TRANSPORTE E TRAÇÃO / TRAFFICABILITY STUDY APPLIED TO WHEELED VEHICLES IN TRANSPORT AND TRACTION
The ability of vehicles to traverse soft soils is an important aspect of their performance. The geological, climate and topography diversity originated, in Rio Grande do Sul, extensive areas of hydromorphic clay soils, as example, Planssoils and Gleissoils. When saturated of water, these soft soils present low loads support, difficult agricultural machinery

10. Simulation of viscous flow around a circular cylinder near a moving ground
The objective of this paper is to study the vortex shedding from a circular cylinder near a moving ground; this is done using the Vortex Method. A moving ground has been widely used in the field of experimental vehicle aerodynamics, especially of high-performance racing cars, to properly consider the ground effect on the vehicles aerodynamic. In experimental

11. Geotechnical characteristics of unpaved roads of Bauru/SP / Caracteristicas geotecnicas de estradas não-pavimentadas no municipio de Bauru/SP
The road net, represented by the highways and unpaved roads, has a vital importance for a nation. The rural and unpaved roads have great importance in the social and economic scope of the country; therefore they are responsible for the access of the agricultural population to the urban services, beyond draining great part of the agricultural production. With

12. Evaluation methodology of traffic impacts on historic preservation area / Metodologia de avaliação dos impactos dos transportes urbanos em áreas de preservação histórica
Historical preservation, nowadays, is a great challenge searching for the cultural identity in the cities. Property deterioration and degradation can be caused by a lot of factors, including the fast growth and development of the cities increase the traffic flow and in most of the cases request a widening of the road and, because of which buildings had to be
