Kortleven, M. (author)
In this research computational fluid dynamics (CFD) is used to model a vertical axis wind turbine. Well known turbulence models | i.e. the k-epsilon and k-omega SST model | are used and compared in their performance against each other and a set of experimental data. The formal research question is "What models are available for the simulation of...

In open-pit mining on a bench level, the dig-limit optimization problem is deciding whether to classify a Selective Mining Unit(SMU) as waste or whether to classify it as ore. SMU’s with high ore grades are profitable for the mining operation, but due to equipment size a whole frame of SMU’s has to be classified as either ore or waste. In this...

This thesis concerns the cap set problem in affine geometry. The problem is illustrated by the card game SET and its geometrical interpretation in ternary affine space. The maximal cardinality of a cap is known for the dimension one to six. For the four lowest dimensions, a maximal cap is constructed and the optimality of its size proven. From...

Interest in phylogenetic trees for histories of species and DNA has spawned many problems, one of which is TreeContainment; a problem that asks whether a tree is contained within a network. The TreeContainment problem is proven to be NP-hard for general trees and networks, however it is solvable in polynomial time for networks that meet the tree...

This thesis provides you with basic information on graph theory as well as phylogenetic networks, it studies the relationship between undirected (unrooted) and directed (rooted) phylogenetic networks, based on the manuscript 'Rooting for phylogenetic networks' . Undirected phylogenetic networks can be oriented to become a directed network. In...

With the growing wealth and economy of a country, there are an increasing amount of small and big businesses. Every company has its own marketing strategy that it uses in order to lure customers away from their competition and increase their sales. Choosing the perfect time to advertise or discount several products is of essence for a company to...

The Beam Dump Facility (BDF) is a new fixed target facility proposed to be installed in the North Area of CERN. Currently in its design phase, the BDF is aimed at the Search for Hidden Particles (SHiP) experiment, which purpose is to investigate the origin of dark matter and other lightly interacting particles. The BDF target/dump sits at the...

In the framework of JAXA's MMX mission to explore the Martian moon of Phobos, an analysis of the stability of three-dimensional quasi-satellite orbits in the Mars-Phobos circular restricted three-body problem was conducted. For this analysis, notions of co-orbital motion, interpreted as the slow motion of the guiding center of the trajectory...

High frequency high voltage power supply has been widely applied in many industrial applications such as the medical X-ray machine and eletrostatic precipitators. As a part of the high frequency high voltage power supply, the electrical performances of the voltage multiplier circuit will influence the behaviors of applications like the X-ray...

The Netherlands policy on electricity steers towards a carbon neutral power generation in 2050. Among<br/>the studies that focus on long term power system research, none use the starting point of a 100%<br/>renewable power system in 2050. It is unknown if such a system is technically feasible given the<br/>variability of wind and solar. The...

Self-driving vehicles are the future of automotive engineering. Systems that take over control from the driver are developed to be able to interact with the conditions of the road and other obstacles. To develop these systems, developers use vehicle models to simulate the behaviour of the moving vehicle. The systems developed using these models...

Population growth, meat-focused diets and emerging industries are increasing stress on water, energy and food (hereafter: WEF) supply around the globe. As stress on the resources rises, the interdependencies between the sectors become more apparent and often lead to unforeseen chain reactions. An example of which is: a drought leads to...

This thesis concerns the optimal design of wind turbine blades for bend twist coupling effects. Bend-twist coupling effects can prove to be an effective way of reducing fatigue damage and root bending moments for a wind turbine blade. However, how can bend-twist coupling be incorporated into a wind turbine blade considering the many structural...

Vessels are becoming more and more optimized towards their mission and an increasing amount of systems are considered during this optimization. Most of these considerations occur at an early design stage, where data is scarce and their impact is large. <br/>This research aims to aid designers in considering this growing forest of possible system...

This research aims at modeling the trajectory followed by the Galileo spacecraft during a variety of flybys about the Galilean moons. The chosen flybys have good Earth’s elevation angles and either low or high closest-approach altitudes, so that the comparison of the two can give relevant insight into the accuracy of the corresponding...

An increase in carbon emission which mostly caused by the transportation sector and electric power generation has been a hot topic nowadays in most countries in the world. To tackle this problem, the share of renewable energy use has been increased by up to 14% in the Netherlands. Moreover, the number of electric vehicles (EVs) on the road also...
