1. Dynamic train/track ballast interaction : linear and state-dependent track models
Sammanfattning : .... LÄS MER
2. Dynamic Train-Track Interaction: Linear and Non-Linear Track Models with Property Scatter
Sammanfattning : A numerical method was developed to investigate the vertical dynamic behaviour of a railway track subjected to the loading of a moving train. The numerical simulations are carried out in the time-domain with what is known as a moving mass model. LÄS MER
3. Towards Mixed Molecular Layers for Dye-Sensitized Solar Cells : A Photoelectron Spectroscopy Study
Sammanfattning : The increasing demand for renewable energy has led to substantial research on different solar cell technologies. The dye-sensitized solar cell (DSC) is a technology utilizing dye molecules for light absorption. LÄS MER
4. On the Influence of Rail Vehicle Parameters on the Derailment Process and its Consequences
Sammanfattning : This thesis aims at systematically studying the possibilities of minimising devastatingconsequences of high-speed derailments by appropriate measures and features in thetrain design, including the running gear. The course of events immediately afterderailments is studied with respect to whether the train stays upright and close to thetrack centre line or deviates laterally with probably serious consequences.

5. The reasoning behind social work intervention design
Sammanfattning : In social work, the methods for achieving policy goals are often subject to some degree of local and case-by-case autonomy. This autonomy enables the design of interventions to be negotiated between different actors, which are underpinned by diverse logics, interests, and knowledge-bases. LÄS MER
