An experimental investigation was done regarding the propulsion system and airframe integration issues associated with the novel Flying V configuration. The experimental investigations involved a series of wind tunnel tests with a 4.6% scale half model, conducted in the TU Delft OJF low speed wind tunnel. Balance measurements allowed significant...

Pretreatment and densification processes such as torrefaction coupled with pelletization have proven to be valuable techniques to convert biomass to solid biofuels. Presently, waste streams from the torrefaction process in the form of volatiles are usually combusted to generate heat required for the torrefaction process. Nevertheless, the...

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...

In this thesis, a new method to approximate the cost function of Low-Thrust, Multiple-Gravity-Assist interplanetary trajectories using a Machine Learning surrogate is proposed. This method speeds up the optimization process without fine tuning of the surrogate parameters for every individual case. The computational cost of obtaining training...

This study aims to assess the role and need of (seasonal) thermal energy storage in the next generation renewable, and sustainable central heating systems for the built environment in the Netherlands. Specifically, the neighbourhood "Karwijhof" in the city Nagele which is transitioning to a collective renewable district heating network...

This thesis studies the possibility of energy increase in tape-spring assemblies through stacking, defined as the practice of placing tape-springs on top of each other in parallel. consists of five chapters. Chapter 2 consists of a paper that presents a theoretical approach to stacking of tape-springs, and studies the potential of energy storage...

In this master thesis project the initial steps for the design of a new wind tunnel<br/>for aeroacoustic measurements are made. Well-documented sizing methods for<br/>different wind tunnel parts were found in a literature study and were used<br/>together with 2D CFD simulations to create a new wind tunnel design. Thick<br/>corner vanes were used...

Part of the goal of Europe’s Strategy Vision Zero is to eliminate all severe cycling accidents in Europe by 2030. The majority of cycling accidents are single vehicle accidents; this term indicates the absence of collisions with other road participants and implies a fall of the cyclist. Research has shown that mainly elderly cyclists are victim...

The dwindling of natural resources, mainly fossil fuels, and the alarming increase in the global average temperatures, are the biggest concerns of the engineering and scientific community of 21st century. Studies have found that known reserves of oil and natural gas will last another 50 years. Coal will last another 110 years, which points...

Total Hip Arthroplasty (THA) is a procedure where a defective hip joint with pain symptoms or functional impairment is replaced by a hip prosthesis. During this procedure, the optimal hip prosthesis should be chosen and placed in the correct orientation to achieve a stable hip joint. Failure to do so can lead to dislocation, mechanical failure...

Superconducting microwave resonators based on coplanar waveguides (CPWs), which allow for on-chip implementation, have a wide variety of uses, from the coupling of qubits to the detection of photons from interstellar clouds. With the integration of a bias circuitry, the already versatile resonator will become even more so. However, applying a DC...

According to recent survey [1], about 6 billion people live in Low-and-Middle Income Countries (LMICs) who do not have proper access to safe surgical care. There are several reasons behind this, such as lack of funding to the healthcare department, below par maintenance of the available devices, poor infrastructure and most importantly high cost...

In this thesis, a control scheme for lifting parcels using two robot manipulators is presented. The robots do not have a rigid grasp on the object. Instead, they use friction to lift the parcels. First, a controller calculates the desired force to make sure the parcels do not slip. The required force, as well as a trajectory are then sent to a...

Flat plate heat exchangers are widely used in industrial and domestic applications. Industrial plate type heat exchangers generally operate in the turbulent flow regime. Although, increase in flow speeds leads to higher transport of heat, it also causes a rise in the pressure loss which is undesirable. Therefore, to combat the problem of high...

The Labrador Sea is one of the deep convection sites in the world's oceans and the water masses formed here are an important component of the Atlantic Meridional Overturning Circulation (AMOC). To study this linkage, one study in particular used an idealized model of the Labrador Sea where the density variations consists only of temperature...

Large cities in the Netherlands, like Rotterdam, have hundreds of playgrounds, but local governments have little information on how children and adults use them. Usage data can help create playgrounds that better fit with the residents' needs by identifying what elements of a playground are the most popular, and which do not get used. The AMS...

With the increasing share of renewable and thus volatile distributed generation<br/>worldwide, small-scale energy producers, prosumers and consumers will become more and more involved in the overall energy system. These small-scale actors were formerly excluded from the energy market, as legislative restrictions about generation size and legal...

Airports play a key role during humanitarian relief operations. It is therefore important to connect the humanitarian and aviation disciplines to find possibilities to improve these airport operations when operating during and after a humanitarian disaster. This research provides a methodology on how to model, verify, calibrate and validate the...

Thin film solar cell technologies are gaining more favour over first generation PV technologies such as monocrystalline silicon PV modules. This is due to their special characteristics such as lightweight, flexibility and reduced resource consumption. HyET Solar is a Netherlands based company that makes thin film amorphous silicon modules using...

When a large ship enters a port the vessel is navigated by the pilots instead of the captain due to safety reasons. The final part of the berthing manoeuver is the most critical and consists of the vessel moving laterally towards the quay wall. At this point the vessel does not use its own propulsion force anymore but is pushed by the tugboats....
