1. An Integration-Reduction Scheme for Simulation of Large Systems with Local Nonlinearity and Uncertainty - Application to moving load problems in railway mechanics
Abstract : The focus of this research is mainly on computational efficiency, as future work is planned for reliability analysis that will be combined with design optimisation. Both these fields are known to be notoriously computationally demanding. READ MORE

2. Simplified dynamic analysis of railway bridges under high-speed trains
Abstract : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges. This is mainly due to the fact that a train at high speeds can cause resonance in the bridge superstructure. READ MORE

3. Input Estimation in Structural Dynamics
Abstract : Knowledge of time-varying excitation is of importance in the design of a wide range of engineering applications, from spacecraft and processing plants to electronic circuits. Regardless of the actual application or underlying physics, the expected input will play a key role in the determination of adequate system properties and parameters. READ MORE

4. Health problems and work-related stress in Swedish ambulance personnel
Abstract : Background: Previous studies have shown a high incidence of both acute and post-traumatic stress among ambulance personnel. It has been shown that ambulance personnel are at a higher risk of being affected of heart disease, high blood pressure and cancer. Studies have also seen a higher incidence of substance abuse and suicide. READ MORE

5. Control of Static Series Compensator for Mitigation of Power Quality Problems
Abstract : Power Electronics and Advanced Control technologies have made it possible to mitigate the power quality problems and maintain the operation of sensitive loads. Among power system disturbances, voltage dips, swells, and harmonics are some of the severe problems to the critical industrial loads. READ MORE
