van der Tholen, Max (author)Floating offshore wind turbines offer opportunities to harvest wind energy at deep-water locations, where the construction of fixed-base turbines is infeasible. The dynamic power cables, which interconnect turbines and transport the generated electricity, are under large dynamic stresses due to the environmental loads and the motion of the...master thesis 2023

Philippo, Thijs (author)Solar and wind will displace fossil fuels as the main source of energy in a net-zero world. However, renewable energy sources provide intermittent power, hence an energy carrier that enables the balancing of demand and supply is needed. Here green hydrogen comes in place. <br/>In addition, the demand for green hydrogen is expected to rise in the...master thesis 2023

Heringa, Louise (author)The first aim of this master thesis is to explore whether the normal force on the castor wheels can be estimated from IMU data using a machine learning approach. The second aim is to evaluate whether incorporating the changing load distribution due to trunk movement could improve the friction power estimation compared with neglecting changes in...master thesis 2023

Makaveev, Momchil (author)This project proposes and evaluates a novel concept for an airspeed instrument aimed at small hybrid unmanned aerial vehicles. The working principle is to relate the power spectra of the wall-pressure fluctuations beneath the turbulent boundary layer formed over the vehicle’s body to its airspeed. The instrument consists of two microphones,...master thesis 2023

Tapia Barroso, Roderick (author)Future communication scenarios will require massive Multiple-input multiple-output (MIMO) by the use of multi-beam antenna systems. Maximizing the number of beams for a given antenna size is paramount given that the space allocated to the antenna is often limited. This work aims at evaluating the maximum number of beams by analyzing the SIR in...master thesis 2023

Lubbers, Friso (author)The Dutch government has the ambition to be climate neutral by 2050. An important pillar to realizing this ambition is to place large numbers of wind turbines in the North Sea. The Dutch cabinet decided in 2022 to realize around 21 GW offshore wind capacity in 2030, but the offshore wind demand in the Netherlands after 2030 remains uncertain....master thesis 2023
