Superconductors expel magnetic fields, a phenomenon known as the Meissner effect. This effect makes it notoriously difficult to predict the magnetic field around a superconductor. One successful way of calculating these fields is through conformal mappings; coordinate transformations that preserve Maxwell's equations of magnetic fields in free...

Despite stringent safety standards, concrete is prone to various forms of deterioration over time, and the occurrence of cracks is not uncommon. Therefore, the detection and monitoring of deformations in concrete are essential to mitigate the risks associated with structural failure. Implementing a real-time Structural Health Monitoring (SHM)...

ADCS magnetometers on board of satellites suffer from the disruptive magnetic field produced by the satellite itself. For CubeSats and PocketQubes this magnetic field is usually not quantified. If the largest magnetic field sources are known and if there is freedom in the magnetometer placement, the magnetometer is simply placed as far from the...

Indoor positioning systems cannot rely on conventional localization methods, such as GPS, to locate devices because of interference with the structure of buildings. One solution is to use magnetic positioning, which is based on spatial variations in the patterns of the ambient magnetic field. To model magnetic fields, Gaussian process regression...

Indoor localisation is a growing field of interest in recent studies. While GPS (global positioning system) is a standard for outdoor localisation, no such solution exists for indoor applications. The literature provides several methods to obtain the location of indoor systems, often using optical sensors. A small number of recent studies use...

Resonators are useful structures due to their simplicity in modeling, design, fabrication and measurement. They can be measured over a wide range of frequencies, power and temperatures, making them convenient for many experiments. Recently, superconducting resonators started being used to investigate microscopic phenomena which require applied...

The technology of focus in this paper, the applied-field magnetoplasmadynamic (MPD) thruster (AF-MPDT), was developed in the 1960s. However, little research has been conducted for this thruster. There is still the need for an accurate model describing the thruster's functioning, its thrust and the physical phenomenons inside.<br/>This project...

This thesis describes the design of a CMOS magnetic field sensor system for measuring electronic currents. A hybrid system, using Hall plates and a pick-up loop is chosen to obtain improved performance compared to conventional Hall based magnetic field sensors. The pick up loop enables to reduce the current consumption and increases the...

Magnetic soft materials are a newly developed material that can transform into programmed shapes when it is placed in an external magnetic field. It is made out of silicone with embedded magnetic particles that lay in magnetization patterns due to 3D printing them under a magnetic field. Its characteristics are fast, remotely controlled,...

The Earth magnetic field is used in many applications such as navigation. Magnetic field sensors are mainly used on satellites for attitude control and in limited missions as scientific instruments. These magnetic field instruments are: specifically designed for the mission, expensive and/or require knowledge of the magnetic noise sources...

The goal of this research was to perform a 3D end-to-end test on a MR-linac to check the whole workflow using a clinical treatment plan. Dosimetric gel was used to obtain 3D spatial information, with the phantom in the same position for irradiation and scanning. In order to achieve this, fundamental elements of gel dosimetry needed to be...

Mass reduction is one of the main drivers for aircraft design. A big potential for saving mass can be found in part joining. Currently, most parts are joined by mechanical fastening. However, mechanical fastening requires labor intensive work and results in a weight increase especially for composite parts that, due to the mass saving they allow,...

The safety in the high voltage substations rely on the integrity of its grounding grid. A single discontinuity at any part of the grounding grid may cause a swell in touch or step potential that may expose the personnel to a hazard of critical electric shock. It may also lead to malfunction of the protection devices leading to erroneous tripping...

This thesis presents the design, development and first spectroscopy measurements of nanowire-based fluxonium devices. We demonstrate the strong external flux and gate voltage tunability of their spectrum, which allows to accurately tune their first transition frequency over a range of more than 10 GHz. We also show the nanowire fluxonium...

Pile driving can cause plastic deformation to the head of the driven pile, which in turn can lead to connectivity issues when the superstructure is installed. Moreover, plastic deformation reduces the estimated service life of the structure. Therefore, it is necessary to monitor the strain levels during the installation in order to detect if the...

The Wien filter is an important part in the multi-beam inspection microscope that is being developed at the Imaging Physics research group at the TU Delft. The multi-beam inspection microscope uses an array of 20x20 parallel beams with a pitch of 1mmthat scan the sample simultaneously. This way the low throughput of current scanning electron...

We study the flow of supercurrents between two superconducting contacts connected by a 2d layer of graphene. We use a Markov chain Monte Carlo method to find Andreev bound states for circular electron trajectories. Using sample trajectories we estimate the currents as function of the superconducting phase difference between the contacts and the...

Majorana zero modes have been proposed as building blocks of intrinsically fault-tolerant quantum computers. Currently, externally applied magnetic fields are necessary to induce Majorana zero modes in carefully engineered systems. Topological qubit state readout is realized by parity sensing of Majorana islands. However, fast and high fidelity...

The international growing concern for the human exposure to magnetic fields generated by electric power lines has unavoidably led to imposing legal limits. The world health organization sets limits for exposure to magnetic and induced electric fields. Basically, the world health organization references to the guidelines provided by the...
