6. Robust self-localization of mobile robots in dynamic environments using scan matching algorithms
Abstract : The most fundamental task for any mobile robot is to perform self-localization in the world in which it is currently active, i.e. determine its position relative its world. Encoders that count wheel rotations are often used, which can be turned into relative position estimates by mean of integration. READ MORE

7. Aggregating Case Studies of Vehicle Crashes by Means of Causation Charts : An Evaluation and Revision of the Driving Reliability and Error Analysis Method
Abstract : There is a need for increased knowledge about causes to motor-vehicle crashes and their prevention. Multidisciplinary in-depth case studies can provide detailed causation data that is otherwise unattainable. Such data might allow the formulation of hypotheses of causes and causal relationships for further study. READ MORE

8. Safety as a process : From risk perception to safety activity
Abstract : The frequency of occupational accidents in the Swedish food industry and agriculture is high. This thesis has therefore explored the 'process of safety' in order to detect and analyse factors that either hinder or facilitate safety activity and to further develop intervention methods towards increased safety activity.

9. Influence of combined thermal and mechanical loadings on pearlitic steel microstructure in railway wheels and rails
Abstract : One of the most important aspects in railway operation is the interaction between rail and wheel. The contact patch between these two components is around the size of a small coin, and since high loads act on this small area, stresses will give rise to wear and damage in both components.

10. Test Design for Finite Element Model Updating - Identifiable Parameters and Informative Test Data
Abstract : It is important to predict structural phenomena, such as noise and fatigue, stemming from vibrations. To do this, reliable structural dynamic models are needed. To be useful the models have to compare well with reality in the validation against test data; if not, the models should be modified. READ MORE
