1. Environmental Modelling : Learning from Uncertainty
Sammanfattning : Environmental models are important tools; however uncertainty is pervasive in the modeling process. Current research has shown that understanding and representing these uncertainties is critical when decisions are expected to be made from the modeling results. LÄS MER
2. LES stochastic modelling of cavitation with its applications in OpenFOAM
Sammanfattning : Cavitation is a vaporization process that commonly happens in high-pressure injector nozzles nowadays. It has been shown by previous studies that cavitation has a significant influence on the subsequent atomization process, the quality of which would in turn heavily affect the process of combustion.

3. Groundwater Recharge in Crystalline Bedrock : Processes, Estimation, and Modelling
Sammanfattning : Kunskap om grundvattenbildningen är nödvändig för att man ska kunna förutsäga konsekvenserna av grundvattenuttag och underjordsbyggande. Grundvattenbildningen i berggrunden är dock svår att uppskatta. LÄS MER
4. Modelling Sexual Interactions : Sexual behaviour and the spread of sexually transmitted infections on dynamic networks
Sammanfattning : In this thesis we develop statistical and mathematical models to study different factors of relevance for the spread of sexually transmitted infections (STIs). Two special interest groups for STI interventions are considered: sexually active youths and men who have sex with men (MSM). LÄS MER
5. Stochastic modelling in disability insurance
Sammanfattning : This thesis consists of two papers related to the stochastic modellingof disability insurance. In the first paper, we propose a stochastic semi-Markovian framework for disability modelling in a multi-period discrete-time setting. LÄS MER
