1. The development of methods for detection and assessment of safety critical events in car driving
Sammanfattning : Improving our knowledge of drivers behaviour, especially in hazardous situations is a key to understanding why accidents occur and how to improve safety on our roads. Crash surrogate measures have proven to be very useful in traffic safety analysis. LÄS MER
2. The Four-Quadrant Transducer System : for Hybrid Electric Vehicles
Sammanfattning : In this thesis a hybrid electrical powertrain called the Four Quadrant Transducer (4QT) has been evaluated through different driving simulations, which later resulted in the manufacture of a prototype. The simulation of a 12 metric ton distribution truck showed that the 4QT system can reduce the fuel consumption by approximately 30 % during the FTP75 drive cycle. LÄS MER
3. Simplified Life Cycle Assessment Approaches and Potential Impact Shifts
Sammanfattning : Road transport contributes to approximately one quarter of all EU greenhouse gas emissions and is the leading cause of air pollution in cities. There are significant measures aimed at the reduction of use phase environmental impacts; in the EU, these strategies focus on the decarbonisation of road transport, such as through the prioritization of low- and zero-emission vehicles.

4. Injury-induced activation of vascular smooth muscle cells. Role of specific gene expression and intracellular signalling pathways
Sammanfattning : Migration and proliferation of smooth muscle cells (SMC) are important events in the development of atherosclerosis and restenosis following angioplastic surgery. It is important to gain further knowledge about the mechanisms regulating SMC form and function in order to understand the underlying disease process. LÄS MER
