1. Interacting particle systems in a randomly evolving environment
Abstract : This thesis concerns interacting particle systems in a randomly evolving environment. In the first paper, we consider the so called contact process in a randomly evolving environment (CPREE), introduced by Erik Broman. This process is a generalization of the contact process where the recovery rate can vary between two values. READ MORE

2. Interacting Particle Systems: Percolation, Stochastic Domination and Randomly Evolving Environments
Abstract : In this thesis we first analyze the class of one-dependent trigonometric determinantal processes and show that they are all two-block-factors. We do this by constructing the two-block-factors explicitly. Second we investigate the dynamic stability of percolation for the stochastic Ising model and the contact process. READ MORE

3. Interacting particle systems in varying environment, stochastic domination in statistical mechanics and optimal pairs trading in finance
Abstract : In this thesis we first consider the contact process in a randomly evolving environment, introduced by Erik Broman. This process is a generalization of the contact process where the recovery rate can vary between two values. The rate which it chooses is determined by a background process, which evolves independently at different sites. READ MORE

4. Human body composition. Reference data and anthropometric equations. The metabolic syndrome and risk
Abstract : The determination of body composition is a key to the understanding of the relation between obesity and disease. In order to evaluate body composition data, reference values are needed. Since methods with high validity and reproducibility are expensive and often time consuming, simpler techniques based on anthropometry are needed. READ MORE

5. Detection and Characterisation of Salmonella in Animal Feed Samples by PCR-Based Methods
Abstract : Animal feed is a recognised source of Salmonella enterica for farm livestock and may also indirectly cause infection in people consuming foods of animal origin. It is therefore important to have rapid, reproducible and specific methods for the detection of Salmonella in feed, and for the characterisation of strains for further epidemiological investigations or to trace the source of contamination in a production facility.
