Dynamic B0 Inhomogeneity Correction at Low Field (50mT) using Interleaved B0 Mapping: Applied to Turbo Spin Echo and Magnetic Resonance Fingerprinting

Low-field MRI is susceptible to temperature changes in magnet temperature, resulting in time-dependent inhomogeneities. This causes time-dependent phase shifts in the measured signal, leading to image distortions. In this project, a method is proposed to interleave short magnetic field (B0) mapping sequences in the target image acquisition for...

Diffusive behaviour and large deviations of one-dimensional active particles with drift

In this thesis a simple model of an active particle was taken, one including a drift according to its internal state. For this model a diffusion coefficient was determined as well as a rate function for the large deviations. This same model is also applied to electrons, although these particles are not active a diffusion coefficient was also...

Modeling the interaction between wave hydrodynamics and flexible aquatic vegetation

Aquatic vegetation, found in coastal waters and inter tidal areas, has important features for hydraulic engineering solutions, including sedimentation and stabilization of the bed. The increasing demand to predict wave hydrodynamics with aquatic vegetation asks for insight in the mechanisms and improved model methods. Striving to a more...

Hydrodynamics of Wind-Assisted Ships: A Numerical and Experimental Study on a Systematic Series of Bare Hull Models at Drift Angles

With fuel oil the main driver for operational expenses, increasingly stringent regulations on emissions of ships and a growing environmental awareness throughout the industry, the concept of Wind-Assisted Ship Propulsion (WASP) presents itself as a means to reduce fuel consumption. Though a promising concept, the performance prediction of a wind...

Investigation of inland ship resistance, propulsion and manoeuvring using literature study and potential flow calculations

Manoeuvring simulations can be of good use in determining whether an inland ship may be allowed access to a certain channel/river or not. The SURSIM mathematical model is able to predict the necessary manoeuvres and can therefore be used to determine the acceptance of ships on fairways. However, the SURSIM program is mostly developed for use...
