Quantifying myocardial perfusion using 3D magnetic resonance imaging

Myocardial perfusion, the blood flow to the heart muscle, can be evaluated by tracing the passage of a contrast agent using cardiac magnetic resonance (CMR) imaging. This technique, well-established for diagnosing coronary artery disease, is limited by the necessity for breath-holding, subjective assessment, and low myocardial coverage. In this...

Active particles in one dimension: Asymptotic behaviour and collective dynamics

In this thesis, we study the asymptotic behaviour and the dynamics of a one-dimensional active particle model with excluded volume interactions. The model is a version of run-and-tumble motion, where a particle performs both symmetric random walks and active transport. The direction and the speed of the transport are governed by an internal...

Fiber Coupled Sub-nanometer Heterodyne Displacement Interferometry

The integrated circuit industry builds integrated circuits (IC’s) by placing many layers of semi conductive material on top of each other, the smallest details in such a layer are called features. Each layer has its own specific layout and will form together with the other layers three dimensional structures such as transistors, diodes or...

High Energy Density Micro-actuation based on Gas Generation by means of Catalysis of Liquid Chemical Energy

This thesis describes the research for, and the assessment of a new type of energy source and actuation, applicable to a Micro Aerial Vehicle (MAV). From the preliminary study resulted a promising energy source: hydrogen peroxide (H2O2) which is combined with the basic principle of the internal combustion engine for conversion to mechanical...
