1. Initiation of bacteriophage P2 rolling circle replication
Abstract : Viruses are very simple entities. In its most simple form, the virus consists of a protein shell containing genetic material. To propagate the virus needs a host to parasitize, in which it can replicate its genetic material and assembly new virus particles. Viruses that parasitize bacteria are termed bacteriophages.

2. Numerical simulation of shape rolling
Abstract : In the first part of this thesis, the FE program MSC.Marc is applied for coupled thermomechanical simulations of wire-rod rolling. In order to predict material behaviour of an AISI 302 stainless steel at high strain rates generated during wire-rod rolling, a material model based on dislocation density is applied. READ MORE

3. On wear in rolling/sliding contacts
Abstract : The aim of this thesis is to increase the understanding of wear in rolling/sliding contacts such as the wheel-rail contact for railroads and the roller-washer contact for roller bearings. The Stockholm commuter train network has been the subject of papers A and B in this thesis in which the wear and surface cracks on rails has been observed for a period of three years. READ MORE

4. The simulation of car and truck tyre vibrations, rolling resistance and rolling noise
Abstract : The road transportation sector places a severe burden on the environment in the form of CO2 emissions and road traffic noise. Both of these environmental prob- lems can be related to car and truck tyres. READ MORE

5. Perception of rolling noise
Abstract : Due to improvements on combustion-engines and electric-engines for cars, tyre noisehas become the prominent noise source at low and medium speeds. Models existthat simulate the noise produced by a rolling tyre, as do models that auralize differenttraffic situations from a basic data set. READ MORE
