1. Interacting particle systems in a randomly evolving environment
Sammanfattning : 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. LÄS MER
2. Statistical Inference on Interacting Particle Systems
Sammanfattning : Interacting particle systems, and more specifically stochastic dynamical systems, is a mathematical framework which allows for condensed and elegant modelling of complex phenomena undergoing both deterministic and random dynamics. This thesis is concerned with the topic of statistical inference on large systems of interacting particles, with the specific application of in vitro migration of cancer cells. LÄS MER
3. Eulerian-Lagrangian modeling of particle motion in exhaust gas aftertreatment systems
Sammanfattning : In the work to design and optimize new aftertreatment system devices for NOx reduction and particulate matter removal in lean engine exhaust (such as diesel exhaust), it is of great help to be able to perform quick, robust and reliable computer simulations of system performance. A suitable platform for such simulations is Computational Fluid Dynamics (CFD) software. LÄS MER
4. Interacting particle systems in varying environment, stochastic domination in statistical mechanics and optimal pairs trading in finance
Sammanfattning : 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. LÄS MER
5. Experimental and Numerical Investigations of Confluent Round Jets
Sammanfattning : Unconfined multiple interacting confluent round jets are interesting from a purely scientific point of view, as interaction between neighboring jets brings additional complexity to the flow field. Unconfined confluent round jets also exist in various engineering applications, such as ventilation supply devices, sewage disposal systems, combustion burners, chemical mixing or chimney stacks.
