1. Analysis of a car door subjected to side pole impact
Abstract The results of a study on the response of a side impact beam located in a car door to impact loading is presented. The side impact beam is situated in both the front and rear side doors of a vehicle between the inner and outer shells to minimise intrusion into the passenger compartment during a collision whilst absorbing as much impact energy as pos

2. Effect of temperature gradients on the behaviour of jointed plain concrete pavements
Resumo Em muitos países da América Latina os pavimentos de concreto com juntas (JPCP) são calculados usando os métodos da “American Association of State Highway and Transportation Officials (AASHTO) ou da “Portland Cement Association” (PCA), os quais não levam em consideração explicitamente as condições climáticas específicas de cada região

3. Fatigue analysis and life prediction of composite highway bridge decks under traffic loading
Steel and composite (steel-concrete) highway bridges are currently subjected to dynamic actions of variable magnitude due to convoy of vehicles crossing on the deck pavement. These dynamic actions can generate the nucleation of fractures or even their propagation on the bridge deck structure. Proper consideration of all of the aspects mentioned pointed our t

4. A Sensitivity Investigation on the Aeroelastic Dynamic Stability of Slender Spinning Sounding Rockets
ABSTRACT: The present work addresses a sensitivity analysis investigation of the aeroelastic stability margins for the VSB-30 sounding rocket during the atmospheric flight phase. Parametric stability analyses are performed considering variations of the inertia properties of the modular payload. Such variations can be caused by different type and/or number of

5. Modelagem e simulação de processos (corte, carregamento e transporte) na produção agrícola de açúcar e álcool / Modeling and simulation of processes (cutting, loading and transportation) in agricultural production of sugar and alcohol
Este trabalho tem como objetivo simular e analisar as etapas de corte, carregamento e transporte da cana-de-açúcar para o planejamento da produção na indústria sucroalcooleira. As etapas agrícolas são responsáveis por cerca de 30% dos custos totais da produção. Nas simulações aplicou-se o módulo de roteirização em arco do software TransCAD. Es

6. O papel das quimiocinas CCL3, CCL2 e seus receptores na movimentação dentária ortodôntica
Orthodontic tooth movement (OTM) is achieved by the remodeling of periodontal ligament (PDL) and alveolar bone in response to mechanical loading. This process is regulated by pro-inflammatory mediators, such as cytokines and chemokines. CCL2, CCL3 and CCL5 are chemokines involved in osteoclastogenesis and are upregulated in periodontium after mechanical load

7. Avaliação dos fatores de risco biomecânicos presentes na atividade ocupacional de eletricistas
Electrical energy is an essential good that may affect peoples life and the economy. Overhead line workers and construction electricians are the workers responsible for the availability of this good. To perform their occupational tasks these workers are exposed to fatal accidents and musculoskeletal overload. Although of high rates of accidents and musculosk

8. A hybrid methodology to solve the container loading problem with weight distribution and cutting problems
Transport of goods has represented an important role in economic development throughout the history and ship containerization brought great advantages. Its invention in mid-1950s brought down the cost of transport and reduced time for loading and unloading cargo. Consequently, it increased efficiency of port working and reduced handling cargo to hours instea

9. Modelo de decisão para a programação de entrega de concreto produzido em centrais. / A decision model for the problem of scheduling concrete delivery produced in concrete batch plants.
This paper addresses the problem of scheduling concrete delivery produced in concrete batch plants. Such scheduling comprises the decisions of which center should serve each customer and what time each delivery vehicle should be loaded, so as to maximize the total marginal revenue of the system. Vehicle loading capacity constraints per center, fleet availabi

10. Projeto de um veículo aéreo não tripulado para pulverização aeroagrícola / Unmanned aerial vehicle design for agricultural aerial spraying
The Unmanned Aerial Vehicles (UAV s) have a variety of applications, wether monitoring of forest fires, power lines, traffic, crowds, but also can be used for aerial target military applications. Even though it is still somewhat restrict to civil application because of lack of regulation, such vehicles are being developed and studied in the academic sphere.

11. 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

12. Uma abordagem de resolução integrada para os problemas de roteirização e carregamento de veículos
O transporte de cargas desempenha um papel fundamental nos sistemas logísticos uma vez que possibilita o fluxo de produtos entre os elementos dos canais de distribuição, além de representar um elevado percentual de participação nos custos logísticos totais. Desse modo, a eficiência dos serviços de transporte depende diretamente de um adequado proces
