1. Evaluation of Variable Speed Limits : Empirical Evidence and Simulation Analysis of Stockholm’s Motorway Control System
Abstract : Variable Speed Limits (VSL) are often used to improve traffic conditions on congested motorways. VSL can be implemented as mandatory or advisory. The objective of the thesis isto study in detail the effectiveness of VSL. The focus is on both, design parameters and conditions under which VSL are most effective. READ MORE

2. Partial Discharges Studied with Variable Frequency of the Applied Voltage
Abstract : This thesis concerns partial discharge (PD) diagnostics withvariable frequency of applied voltage in the frequency range 1mHz - 400 Hz. The exploration of a new type of spectroscopythat combines partial discharge analysis and dielectricresponse is demonstrated. READ MORE

3. The Influence of Residual Stresses on Constant and Variable Amplitude Fatigue Behaviour of Steel
Abstract : Subjected to dynamic loading, truck components are exposed to variable amplitude fatigue. The fatigue life of components is to a large degree controlled by the behaviour of the surface zones. READ MORE

4. On Electrified Fluid Power Systems in Mobile Machinery
Abstract : High power density in combination with flexible power distribution possibilities and extreme robustness are reasons why fluid power has been the preferred technology in mobile machinery, such as excavators and cranes, since the mid-20th century. In principle, the machines have been powered by a combustion engine which powers a pump, with the output from the pump being distributed to different functions via valves. READ MORE

5. Ventilation System Design - A Fluid Dynamical Study with Focus on Demand Control
Abstract : Ventilation corresponds to a large part of the total energy use of a building and a lot of attention has been paid to how to reduce this energy use. However, much of this work on saving energy has been focused on reduction of the airflows and how this in turn reduces the energy use. READ MORE
