1. Computational Diffusion MRI: Optimal Gradient Encoding Schemes
Sammanfattning : Diffusion-weighted magnetic resonance imaging (dMRI) is a non-invasivestructural imaging technique that provides information about tissue microstructures.Quantitative measures derived from dMRI reflect pathologicaland developmental changes in living tissues such as human brain.

2. Optimisation in strategies in diffusion tensor MR imaging
Sammanfattning : With diffusion MR imaging, the Brownian motion (or self-diffusion) of water molecules is measured. In the corresponding ADC (Apparent Diffusion Coefficient) image, each image element (voxel) represents the average diffusion. In MRI, the diffusion is measured with diffusion gradients along certain directions in space. LÄS MER
3. Distributed Control for Spatio-Temporally Constrained Systems
Sammanfattning : In this thesis, we develop methods leading towards the distributed control of spatio-temporally constrained systems. Overall, we focus on two different approaches: a model predictive control approach and an approach based on ensuring set-invariance via control barrier functions. LÄS MER
