Collaboration between the Global South and Global North is inevitable. It can work. It can be emphatic, effective, and more equal. However, there is a deeply embedded history of colonialism involving power asymmetries that give rise to the dismissal of value systems, which pervert this type of collaboration from being truly realised. Hence,...

Acidizing is a widely used technique for intensification of geothermal wells. At certain conditions, acid injection results in a formation of highly conductive channels, e.g. wormholes. The associated rock matrix dissolution is highly nonlinear and may influence the fluid flow as well as rock properties. Wormhole patterns and breakthrough time...

Due to increasing cost pressure, disturbances from customs and an opportunity seen in reducing costs by increasing the procurement and construction in the Far East, Damen Shipyards Gorinchem is changing the requirements for its supply chain. Changes to the supply chain however not only inflicts a large number of stakeholders, but the cost...

The energy transition is driving extensive changes to global energy systems, including the electrification of heating and mobility, increased renewable electricity generation, and a shift towards sustainable gases like green hydrogen. These changes will need to be accompanied by major investments in energy infrastructure, especially considering...

The Free Energy Principle, which underlies Active Inference (AI), is a way to explain human perception and behaviour. Previous literature has hinted at a relation between AI and Linear-Quadratic Gaussian (LQG) control, the latter being a textbook controller. AI and LQG are, however, defined with different settings in mind: LQG has access to...

Scandals in which governmental ADM tools played a role, have recently brought<br/>about political and societal debate about the potential harms to citizens that such automated systems potentially bring. This thesis focuses on ADM systems which contain an AI component. Based on the knowledge gaps perceived,<br/>the main research question for this...

Low downlink data rates limit the scientific and commercial return from small satellites. Now with constellations of small satellites becoming popular, the amount of data generated in low Earth orbit will be greater than ever. A novel data downlink architecture for small satellites is investigated that uses non-geostationary orbit (mega-...

The Mid-infrared ELT Imager and Spectrograph (METIS), which will be one of the first-light instruments on the Extremely Large Telescope (ELT), will be equipped with an Adaptive Optics (AO) system that will use a natural guide star as reference for the correction of the wavefront errors, introduced by the atmospheric turbulence. Even though this...

The reduction of turbulent skin-friction drag has the potential to generate numerous societal benefits. In large-scale industrial applications, the largest share of energy consumption goes into overcoming the friction drag produced by turbulent boundary layers formed on the outside wall. Estimates assess that over 50% of the total fuel burn is...

Gas giant satellites are generally believed to form in circumplanetary disks (CPDs): a gas disk containing solid particles that accumulate to form moons over time. The discoveries by the Cassini­ Huygens mission have led to a revision of the birth environment of the Saturnian system. The aim of this thesis is to constrain the formation...

The number of people working night shifts has been steadily increasing over the past 20 years. Although shift workers have known this for a long time already from first-hand experience, the Dutch national institute for public health and the environment has recently published advice to minimize night (shift) work, as it is detrimental to the...

In recent years wind turbines have become increasingly large to increase energy yield and cost-effectiveness. This has led to taller turbine towers, subjected to larger loads. As a result, Lagerwey turbines experience lateral tower vibrations at different resonance frequencies. These vibrations result in rotor speed measurement disturbances due...

Practice is central in mathematics skill acquisition. The practice process can be facilitated by flexible digital exercise systems, supporting personalized learning and providing students with parameterized, open answer exercises containing answer-specific feedback. However, current solutions for authoring these exercises lack efficiency and...

While SQL engines are now capable of detecting a large number of syntactic mistakes, most often semantic errors are not detected, which can lead to serious performance issues or even security vulnerabilities being introduced in the system. This thesis proposes a set of 25 validated heuristics together with a new rule-based static analysis tool...

Straight fiber variable stiffness laminates use multiple overlapping patches to tailor the fiber orientations in particular regions of the laminate. A novel, automated framework for the design of manufacturable laminate has been developed using different stages. In the first and second stage an optimal stiffness distribution is determined using...

A new semi-analytical model is developed to predict the dynamic response of slender gates in combination with an overhang, which are subjected to standing waves. Still little is known for these types of gates for this specific forcing type. The semi-analytical model is still in its development phase and must be validated on its performance. This...

Coronary artery disease (CAD) is one of the leading causes of death and disability worldwide. In CAD, the coronary arteries, that supply the myocardium with oxygen, are narrowed or even blocked by a process called atherosclerosis. Invasive coronary angiography (ICA) is the gold standard for the diagnosis of CAD, as well as for intraprocedural...

The Lunar Zebro is a small six-legged robot. It has the potential to be used in a swarm carrying out objectives like exploring planetary surfaces. A new step towards autonomous navigation is made with the newly developed Obstacle Processing ALgorithm (OPAL) using primarily open-source libraries. This study showed that the initial iteration of...

Pick and place systems that operate in a warehouse setting have been studied a lot recently due to the high economic value for e-commerce companies. In this thesis, the focus is on the perception pipeline that performs object recognition given a certain input data stream (typically RGB-D images). Impressive results regarding object recognition...
