1. Metal film growth on weakly-interacting substrates : Multiscale modeling
Sammanfattning : Thin films are nanoscale layers of material used to functionalize surfaces or to serve as building blocks in more complex devices. In recent years, thin metal films have become vital for modern devices within, e.g. LÄS MER
2. Mesoscale Simulations of Atmospheric Flow in Complex Terrain
Sammanfattning : The MIUU mesoscale model was further developed, in order to include information on large-scale atmospheric fields from global or regional atmospheric climate- and weather-prediction models. For this purpose, a new lateral boundary condition was developed and implemented into the model. LÄS MER
3. Computational Multiscale Modeling of Pearlitic Steel
Sammanfattning : The objective of this thesis is to investigate the possibilities to describe the mechanical behaviorof a pearlitic steel by using computational homogenization, or multiscale modeling. The proposed model contains three scales: the engineering macroscale, the mesoscale representing the colonies of the pearlite and the microscale containing the individual cementite lamellae and the ferrite matrix.

4. Observing and Modeling Precipitation in the Tibetan Plateau region - from large-scale processes to convective storms
Sammanfattning : Climate change in mountain regions has far-reaching societal impacts such as increased risks for natural hazards and water scarcity that may affect billions of people in the downstream regions. Precipitation changes play a critical role in these impacts due to their effects on river runoff and flooding. LÄS MER
5. Global Climatology and Regional Modeling of Coastal Low-Level Jets
Sammanfattning : Localized coast-parallel wind-speed maxima at low altitude, known as coastal low-level jets (CLLJs) have important ramifications to the coastal climate and a number of human activities. This thesis documents the existence of the CLLJs around the globe including their mesoscale structure, dynamics and spatio-temporal variability. LÄS MER
