1. Anti-paternalism and Public Health Policy
Sammanfattning : This thesis is an attempt to constructively interpret and critically evaluate the liberal doctrine that we may not limit a person’s liberty for her own good, and to discuss its implications and alternatives in some concrete areas of public health policy. The thesis starts theoretical and goes ever more practical. LÄS MER
2. Wheel-rail Interaction Analysis
Sammanfattning : A general approach to numerically simulating wear in rollingand sliding contacts is presented in this thesis. A simulationscheme is developed that calculates the wear at a detailedlevel. LÄS MER
3. Modelling of wear and galling in press hardening simulations
Sammanfattning : Implementation of press hardened parts in automobile responses to the requirement of reduced carbon dioxide emission because the press hardened part has very high ratio of strength to weight. Furthermore, ultra high-strength steels (press hardened parts) increases the vehicle safety. LÄS MER
4. Out-of-Round Railway Wheels - Causes and Consequences An Investigation Including Field Tests, Out-of-Roundness Measurements and Numerical Simulations
Sammanfattning : Causes and consequences of out-of-round railway wheels are investigated through literature studies, full-scale field experiments, out-of-roundness measurements, and numerical simulations. Both defects around the complete wheel circumference (e.g. polygonal wheels with wavelengths up to one wheel circumference) and local defects (e. LÄS MER
5. Modelling of wear and tribofilm growth
Sammanfattning : Wear is a consequence of nature which becomes costly if uncontrolled. Basic wear protection is provided by lubrication which will decrease the severity of the contact between asperities. LÄS MER
