1. Response of cable-stayed and suspension bridges to moving vehicles : Analysis methods and practical modeling techniques
Sammanfattning : This thesis presents a state-of-the-art-review and twodifferent approaches for solving the moving load problem ofcable-stayed and suspension bridges. The first approach uses a simplified analysis method tostudy the dynamic response of simple cable-stayed bridgemodels. LÄS MER
2. Human Postures and Movements analysed through Constrained Optimization
Sammanfattning : Constrained optimization is used to derive human postures and movements. In the first study a static 3D model with 30 muscle groups is used to analyse postures. The activation levels of these muscles are minimized in order to represent the individual's choice of posture. LÄS MER
3. Towards Optimization of Railway Turnouts
Sammanfattning : The turnout (Switch & Crossing) is a vital component in railway networks as it provides flexibility to traffic operation by allowing trains to switch between tracks. The flexibility comes at a cost as the common lack of a transition curve in the diverging route together with the variation and discontinuities in rail profiles result in higher rail degradation rates than in regular track.
