11. Structural and evolutionary aspects of stochastic processes
Sammanfattning : Stochastic processes constitute a broad class of objects of central importance in complex systems. The main structural aspect of stochastic processes that is treated in this thesis is their hierarchical dynamics. LÄS MER
12. Anisotropic Protein Interactions in Salt Solutions and at Interfaces: Coarse Grained Modeling
Sammanfattning : Anisotropic protein interactions have a strong orientation dependence resulting from an uneven distribution of charged and hydrophobic residues on the protein surface. They play an important role in protein behaviors such as protein association, surface adsorption and phase separation. LÄS MER
13. Super-grid Linear Eddy Model (SG-LEM): Efficient mode- and regime-independent combustion closure for Large Eddy Simulation (LES)
Sammanfattning : Next-generation combustion technology such as ‘lean burn’ and HCCI (Homogeneous Charge Compression Ignition) present new challenges for combustion modelling. The presence of locally varying combustion modes (premixed vs. non-premixed) and regimes (fast/non-fast chemistry vs. LÄS MER
14. Multiscale Modeling of Molecular Sieving in LTA-type Zeolites : From the Quantum Level to the Macroscopic
Sammanfattning : LTA-type zeolites with narrow window apertures coinciding with the approximate size of small gaseous molecules such as CO2 and N2 are interesting candidates for adsorbents with swing adsorption technologies due to their molecular sieving capabilities and otherwise attractive properties. These sieving capabilities are dependent on the energy barriers of diffusion between the zeolite pores, which can be fine-tuned by altering the framework composition. LÄS MER
15. Complexity and Error Analysis of Numerical Methods for Wireless Channels, SDE, Random Variables and Quantum Mechanics
Sammanfattning : This thesis consists of the four papers which consider different aspects of stochastic process modeling, error analysis, and minimization of computational cost. In Paper I, we construct a Multipath Fading Channel (MFC) model for wireless channels with noise introduced through scatterers flipping on and off. LÄS MER
