MR-based Electrical Properties Tomography (EPT) is a medical imaging modality to reconstruct the electrical conductivity and permittivity inside the human body based on the magnetic field data obtained from an MRI system. Currently, 2D CSI-EPT implementation is able to generate reliable reconstructions under special assumption of electromagnetic...

Future energy systems will present high penetrations of variable renewable energy (VRES). Due to the uncertainty that is related to the intermittency of wind and solar energy, and loads such as electric vehicles, the need for flexibility will be higher. This research identifies the possible sources of flexibility in a power system. Firstly,...

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...

Due to recent advancements in automated driving systems, drivers are able to withdraw themselves from the control loop of the vehicle in certain driving situations. However, system limits occur relatively frequently, which results in the driver having to take back control. It is argued most currently used take-over quality quantification methods...

Wind energy is the most promising renewable energy source for the Netherlands in the energy transition period. However, the investment costs of the offshore wind are huge. Until now, the government was supporting the investments in wind farms with subsidy schemes irrespective of the electricity market dynamics. The latest large-scale offshore...

Sailing against the wind follows a zig-zag trajectory. To find the optimal time and path-trajectory to move from one target to another during a race, this study analyzes how the wind determines the optimal time-path of Lasers, one of the smallest sailboats that compete during the summer Olympic Games.
To answer this question, this study uses...

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...

In 20 years, from 1996 to 2016, global cumulative container port throughput had an average annual growth rate of 6.3%. Furthermore, the average global transshipment incidence increased from 11% in 1980 to a stable 27% in 2017. This change in transshipment market dynamics has led to opportunities for potential port investments or disinvestments....

This research concerns the problem of scheduling aircraft maintenance tasks, that must be carried in multiple maintenance checks to keep the aircraft airworthy. During this research the allocation of maintenance tasks to their maintenance opportunities is referred to as the task allocation problem. It is a complex combinatorial problem that is...

Currently, KLM's apron processes work in separate silos and there is only minimal integration. The result is that processes tend to work to a local optimum instead of a global optimum. A Transport Logistic Control Tower is a centralized information hub from which integral decisions can be made which could benefit the overall turnaround process...

Vibrations are experienced as unwanted dynamic motions and the industry takes a lot of care to reduce these motions to improve comfort and to increase vehicle component durability. The properties of rubber, being generally soft while showing large inherent damping, makes the material a perfect choice to use in vibration isolators. To minimize...

In the Netherlands, wind power has the highest potential for future development compared to alternatives such as solar PV and biomass. The intermittent nature of the wind power resource calls for novel approaches to supply and demand management, as well as power quality assurance. Energy storage technologies allow for the separation between...

The area surveillance problem is the problem of surveying a known or an unknown area with the main purpose of detecting objects. This thesis will tackle the problem of how to employ a group of mobile-sensors for surveying an unobstructed area in an optimal manner. The mobile-sensors should make use of their onboard computers and they should...

In the European Union Road freight transport volume is expected to grow 78% between 2000 and 2030, which results in more trucks on the road network. The worldwide estimated trend shows an increase of 150 million freight vehicles and an increase of 240 million passenger vehicles. The growth of both vehicle classes will have a major impact on the...

Baggage handling systems (BHS), are complex and integrate systems hidden within an airport. In this thesis, a model is developed which can generate BHS concept design automatically. This means that the model defines the type and amount of equipment needed and is able to develop a 3D model that can be used for volume reservation. The model takes...

Tensegrity is a structural form that is defined as a set of rigid elements suspended in a net of continuous tension. This structure shows potential for compliance, impact tolerance and mechanical robustness. However, its non-linear coupled dynamics and often complex geometry require advanced control strategies. An actuator reference planning...
