Bus Rapid Transit (BRT) corridors and systems have emerged in the past three decades as affordablesolutions of medium capacity public transport services to highly urbanized areas, especially in LatinAmerica and Asia. In Stockholm, trunk bus lines have gained priority over mixed traffic over the yearsthrough exclusive bus lanes, signal priority, and reliability control, for example, but no complete BRTsolution has been implemented yet. Among the inner-city trunk lines, Line 4 is the most demanded witharound 70,000 passengers boarding the service daily. This thesis proposes, then, to assess theoperational impacts that BRT solutions as segregate median lanes, stations with off-board farecollection and platform level boarding and alighting through all bus doors, full signal priority andheadway control strategy, would have in bus Line 4, using a microscopic simulation approach. Twoscenarios were simulated, and the results compared to the existing conditions (Base Scenario).Scenario 1 considered a 5-minute headway service and Scenario 2, 3-minute headways. Overall, theproposed scenarios reduce travel times by 37.6-49.1%, increase average operational speeds (includingdwell times) by 60.4-96.6%, decrease dwell times by 57.9-65.6%, decrease delays by 18.4-36%,decrease vehicle occupancy rates by 3.5-44.9% and improve the Coefficient of Variation of theheadways from 0.83-0.85 in the Base Scenario to 0.1 in Scenario 1 and 0.2 in Scenario 2. As a resultof the reduction in travel times, a BRT service would need 13 buses to operate a 5-minute headwayand 21 buses for a 3-minute headway, against 27 vehicles that are used currently for a 4 to 6-minuteheadway during peak hour.

This diploma thesis contains a summary of the general information about the torsion vibration of the crankshaft. The main task is to prepare a flexible model of the crankshaft in the FEM program ANSYS and the subsequent export into the MBS ADAMS / Engine. According to parameters the model of four-cylinder line tractor engine with flexible crankshaft is built. Crank mechanism is analyzed to determine the natural frequencies and natural modes. Finally the results are evaluated and compared with analytical calculations.

Para evitar inferências genéticas e oriundas de percepções decorrentes da experiência prática, própria de quem atua no setor, optei por adotar o método de estudo de caso para identificar se essas percepções se comprovariam a partir de uma pesquisa empírica. Para tanto, elegi a PPP da Linha 4, cuja análise dos processos de gestão instaurados ao longo da execução desse contrato revelou questões interessantes e muito úteis para traçar um diagnóstico do tema e, a partir disso, contribuir – assim se espera – para reflexões visando à melhoria do ambiente de execução de negócios entre o setor público e o setor privado, cujas percepções de risco são especialmente mais sensíveis quando se trata da celebração de parcerias de investimento. / The purpose of this Master's thesis is to discuss the management of long-term investment contracts – concessions and public-private partnerships – specifically to evidence the current environment involving the management of these contracts by the Public Administration. To avoid genetic inferences, it was decided to adopt the case study method to identify relevant questions on the subject. For this purpose, the PPP of Line 4 was chosen, which empirical analysis of the administrative procedures established during the execution of this contract showed interesting and very useful questions to draw a diagnosis of this work`s subject and also contribute to reflections aimed at improving the business environment between the public and the private sector, where perceptions of risk are especially more sensitive when compared to other public businesses cases.
