21. Methods for the analysis and characterization of brain morphology from MRI images
Sammanfattning : Brain magnetic resonance imaging (MRI) is an imaging modality that produces detailed images of the brain without using any ionizing radiation. From a structural MRI scan, it is possible to extract morphological properties of different brain regions, such as their volume and shape. LÄS MER
22. On Reliability Methods Quantifying Risks to Transfer Capability in Electric Power Transmission Systems
Sammanfattning : In the operation, planning and design of the transmission system it is of greatest concern to quantify the reliability security margin to unwanted conditions. The deterministic N-1 criterion has traditionally provided this security margin to reduce the consequences of severe conditions such as widespread blackouts. LÄS MER
23. Methods development for the investigation of the mammalian genome radial architecture : the quantitative side
Sammanfattning : The nucleus of mammalian cells cradles the genome, an ensemble of nucleic acid macromolecular polymers that store information in a physical form. For a cell to perform life-sustaining processes, reading and utilizing the information encoded in the genome monomers’ sequence is necessary. LÄS MER
24. Developing novel diffusion MRI methods for comprehensive analysis of restricted and anisotropic self-diffusion system
Sammanfattning : Diffusion MRI is a non-invasive imaging technique used to study the microstructural properties of biological tissues by observing the self-diffusion of water molecules. Traditional diffusion MRI methods, based on the pulsed gradient spin-echo sequence, employ magnetic field gradients to encode information about translational motion. LÄS MER
25. Numerical methods for the Navier–Stokes equations applied to turbulent flow and to multi-phase flow
Sammanfattning : This thesis discusses the numerical approximation of flow problems, in particular the large eddy simulation of turbulent flow and the simulation of laminar immiscible two-phase flow. The computations for both applications are performed with a coupled solution approach of the Navier-Stokes equations discretized with the finite element method. LÄS MER
