1. Road profile statistics relevant for vehicle fatigue
Sammanfattning : Road profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). LÄS MER
2. Automated Gravel Road Condition Assessment : A Case Study of Assessing Loose Gravel using Audio Data
Sammanfattning : Gravel roads connect sparse populations and provide highways for agriculture and the transport of forest goods. Gravel roads are an economical choice where traffic volume is low. In Sweden, 21% of all public roads are state-owned gravel roads, covering over 20,200 km. LÄS MER
3. Ride Comfort Optimization of Buses
Sammanfattning : As the design of buses is constantly improving, passengers are becoming more fastidious and the demand for a more comfortable travelling environment is constantly increasing. The main objective of this thesis is to contribute to the understanding of how the design of buses affects the ride comfort characteristics. LÄS MER
4. Assessment of crosswind performance of buses
Sammanfattning : When driving a vehicle on the road, the driver has to compensate continuously for small directional deviations from the desired course due to disturbances such as crosswinds, road irregularities and unintended driver inputs. These types of deviations have a tiring effect on the driver and should therefore be minimised. LÄS MER
5. Training to become a master mariner in a simulator-based environment: The instructors’ contributions to professional learning
Sammanfattning : In higher education programs that aim to prepare students for professional performance in safety-critical work activities, the introduction of simulators is seen as a fundamentally restructuring of the ways in which professional skills are developed and assessed. This, in turn, creates new challenges and possibilities for both teaching and learning a profession. LÄS MER
