1. Short and long-term effects of exposure to low dose and low dose rate of gamma radiation : using in vitro and in vivo models
Sammanfattning : Assessment of human health risks from exposure to ionizing radiation (IR) is mainly based on the extrapolation of results from epidemiological studies on populations exposed to relatively high doses and often at high dose rates (HDR). Risk estimates after exposure to low doses and in particular at low dose rates (LDR) remain controversial due to a lack of epidemiological evidence. LÄS MER
2. Mathematical Models of Molecular Evolution
Sammanfattning : This thesis deals with mathematical models of Darwinian evolution in populations of simple living organisms. We study models which describe how the representation of different gene sequences in the population is affected by the fundamental forces of evolutionary processes, such as selection pressure, the mutation rate and the time dynamics of the underlying fitness landscape.

3. Investigation of radiation-induced genetic and epigeneticeffects using cultured cells and Drosophila as experimental models: with focus on dose rate
Sammanfattning : .... LÄS MER
4. Bayesian networks: exact inference and applications in forensic statistics
Sammanfattning : Exact inference on Bayesian networks has been developed through sophisticated algorithms. One of which, the variable elimination algorithm, identifies smaller components of the network, called factors, on which local operations are performed. In principle this algorithm can be used on any Bayesian network. LÄS MER
5. Exact inference in Bayesian networks and applications in forensic statistics
Sammanfattning : Bayesian networks (BNs) are commonly used when describing and analyzing relationships between interacting variables. Approximate methods for performing calculations on BNs are widely used and well developed. LÄS MER
