Natural gas has been a significant source of energy for the Netherlands for a long time, but due to developments such as climate change awareness and increased seismic activity in the Groningen area, the Dutch Government has decided to shift away from natural gas and look for alternatives. Hydrogen gas is such a contender, as it can partly use...

The Low Earth Orbit (LEO) region has been attractive to many space agencies and organisations because of its ease of access and the ideal opportunity for remote sensing. Due to the low altitudes, a satellite's orbital state is highly affected by the atmospheric drag force acting on the satellite's body. The largest variation in this drag force...

System safety and reliability assessment relies on historical data and experts opinion for estimating the required failure probabilities. When data comes from different sources, be it different databases or subject domain experts, the estimation of accurate probabilities would be very challenging, if not impossible, and subject to high epistemic...

This thesis presents a transformable metamaterial, inspired by origami. Generally, metamaterials are build up following the periodicity of Bravais lattices. This study aims to design a structure not following the Bravais lattices, but rather a different type of symmetry which tiles a sphere, in order to expand on current design studies. In this...

Organisations find it more and more difficult to deal with our changing times, as our world has drastically changed over the last decades. This has led us to believe that organisational theory and practice from the last decades just does not hold up anymore. They have created organisations that made sense then, but do not necessarily now....

This work proposes a new charge pump design suitable for energy harvesting on small human wearable devices. By using only one system for both cold start and high efficiency harvesting, the required silicon area is heavily reduced. The most fitting energy transducer is determined to be a photovoltaic cell, based on aspects of voltage, power and...

Radiofrequency ablation (RFA) is a localized thermalintervention technique with the purpose to destroy small tumours (< 3 cm) byheating the tumour tissue. Due to various challenges with targeting andvisualisation during RFA, the clinical need of steerable needles is present forradiologists. Helwig, B.P. developed a new...

The global environmental issues are becoming more and more pressing. These issues ask for not only changes on a product-level but also on a system-level (Ceshin, 2013). One of the potential solutions can be to facilitate more sustainable consumption. Sustainable consumption patterns can potentially be created by product-service systems (PSSs)....

In de zeventiende eeuw liet de stedelijke elite op grote schaal buitenplaatsen en landgoederen in het Hollandse laagland aanleggen. Zij verkoos de meest welgelegen plaatsen voor hun zomerverblijf met speelhuizen, bomenlanen en geschoren hagen. De voorkeur om in elkaars nabijheid te gaan wonen was veelal ingegeven door eenzelfde gebruik of...

Very complex flows can be expensive to compute using current CFD techniques. In this thesis, models based on deep learning were used to replace certain parts of the flow domain, with the objective of replacing well-known regions with simplified models to increase efficiency. To keep the error produced by the deep learning model bounded, a...

The development of technology in the emergency sanitation sector has not been emphasised sufficiently considering that the management of human excreta is a basic requirement for every person. The lack of technology tailored to emergency situations complicates efforts to cater for sanitation needs in challenging humanitarian crisis. Sanitation...

A young boy with type 1 Diabetes Mellitus is supported by a social robot on the road to self-management. The robot has knowledge on the goals that the boy needs to reach, as discussed with his health care professional. The robot also knows the boy’s activity options and preferences. It suggests activities based on this knowledge, but also...

Bouwteam is a collaboration agreement in which the contracor is involved early on to work together with the client to make a design in which the knowledge of the client and the contractor is used optimally. Through the years the Bouwteam has been influenced by integrated contracts and has been changing in a variety of ways. Nowadays, there is...

The German Aerospace Centre (DLR) has in the past years been performing test runs with their experimental sub-scale combustion chambers to measure and investigate the effects of unstable combustion. Some of these investigations are focused on the heat flux to the chamber walls, changes in which can cause a significant shift in chamber wall...

Stochastic systems have been widely investigated and employed in numerous
applications in different areas such as finance, biology and engineering as
they allow accounting for imprecisions so often faced in every practical tasks. Often that task would require to find the best action sequence in order to optimize the outcome. When the...

Comparing spreadsheet files is a new, unexplored research domain in computer science. Methods for regular file comparison are not straightforwardly applicable to spreadsheet files, because they are fundamentally different. Spreadsheets are binary files, the structure of spreadsheets is two-dimensional, they contain both data and calculations,...

In this PhD thesis, we investigate the microstructural evolution and damage in different steel grades used in railway applications such as switches, crossings and curved tracks, which are the key components in the rail transportation industries around the world. The damage in these components leads to a maintenance cost of billions of Euros per...

Once a semi-submersible is operating at an inconvenient draft (A shallow draft with limited water column above the pontoons), the passing waves over the pontoons can not keep their linear motion and energy will be transferred to higher harmonic wave frequencies. This means the hydrodynamic response will also contain energy at these higher...

Metallic pigments are versatile, eye-catching and increasingly utilized materials to create unique effects in plastics. However, these pigments usually show a higher sensitivity to weathering factors like UV light and water in polymer formulations than other pigments. In the particular case of Polyvinyl Chloride (PVC), this is even more evident...

Energy-based surgical instruments are increasingly used in laparoscopic surgical procedures. For example, the ultrasonic scalpel enables tissue coagulation and -cutting by transferring a mechanical vibration to the tissue. Additionally, real-time sensing is implemented to improve the surgical procedures. Intraoperative ultrasonography is one of...
