6. Modelling and simulation of electromagnetic audible noise generated by traction motors
Sammanfattning : An annoying tonal noise is produced by modern electrical trains duringacceleration and deceleration. This noise is caused by electromagneticforces generating structural vibrations, especially from the traction motors. LÄS MER
7. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction
Sammanfattning : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. LÄS MER
8. When Driving Automation Fails. Drivers' Experiences and Interactions
Sammanfattning : Drivers’ interactions with automation based on experiences from real driving, and results from driving simulators were under investigation in this thesis. The thesis had a mixed methods research approach and was exploratory. Special attention has been given to driver behavior on exposure to unexpected automation failures. LÄS MER
9. Simulation Studies of Impact of Heavy-Duty Vehicle Platoons on Road Traffic and Fuel Consumption
Sammanfattning : The demand for road freight transport continues to grow with the growing economy, resulting in increased fossil fuel consumption and emissions. At the same time, the fossil fuel use needs to decrease substantially to counteract the ongoing global warming. LÄS MER
10. Diastolic left ventricular filling in 50-year-old male and female adults : Evaluation by Doppler echocardiography
Sammanfattning : Left ventricular (LV) diastolic filling abnormalities are seen in many patients with various cardiac disorders. Age is an important determinant of Doppler indices of LV diastolic filling. LÄS MER
