Turbulent scalar mixing is prominent in all sorts of situations, being it in air pollution or making tea. However, this does not often lead to a homogeneously mixed fluid, but rather leads to regions of higher concentrations next to regions with significantly lower concentrations. This can be characterized by dividing the concentration field in...

The aim of this project was the implementation of optical coherence tomography (OCT), an invasive intracoronary imaging (ICI) tool used for the visualization of coronary arteries. The implementation was performed in a structured manner by: (1) A literature review into the current applications of OCT in relation to current standards; (2) A thesis...

Isolation of specific biological phenomena in vitro is critical to understanding living systems, due to cells’ innate capacity to integrate and respond to a wide range of signals simultaneously. Concomitantly, advances in micromanufacturing techniques overlap with progress in tissue engineering to produce microenvironments that better mimic in...

In interplanetary mission design, ballistic capture is the phenomenon by which a spacecraft approaches its target body, and performs a number of revolutions around it, without requiring manoeuvres in between. For a spacecraft to be captured, its gravitational interaction with at least two celestial bodies has to be taken into account. Because of...

Ballistic capture is a transfer method which was first applied in 1990. It allows a spacecraft to approach a target celestial body and enter a (temporary) orbit around it without requiring manoeuvres in between. Ballistic capture is a promising concept, as it is expected to be safer, cheaper, and more flexible in terms of launch windows than a...

In this thesis, the relation between the generator of the OrnsteinUhlenbeck process and the Hamiltonian of the quantum harmonic oscillator is used to derive a new understanding of the evolution of certain quantum states. More precisely, we transform the Hamiltonian with respect to the ground state and corresponding eigenvalue to find that it is...

Almost four million people in the Netherlands who live below sea level are protected by 17000 km of dikes against the water. Since deformation can be an indicator of a developing failure mechanism, information about this parameter can help authorities to detect weak spots in the dutch water defense structures. <br/>In this research, Radar...

In recent years, there has been a widespread increase in the adoption of virtual reality and 3d displays which require many images as input, e.g. head mounted displays or lightfield displays. Real-time rendered imagery for such displays is commonly computed using brute-force rendering pipelines based on forward(+) or deferred rendering pipelines...

Imaging sensors are remarkable devices which are able to capture moments and present them in a form available to us for years to come. With the use of material properties and photon particles, charges can be produced which, in combination with electric circuitry, transform into information understandable to the human eye and eventually the brain...

Power systems have undergone major changes the past few decades, leading to an increase in the frequency of occurrence and severity of blackouts. Intentional controlled islanding constitutes the final resort to rescue the system from a blackout by separating the network into islands in a controlled manner. Various post-separation control action...

As part of a larger project called “Healing Water” this thesis project investigated aspects of minimally invasive water-jet drilling as a technology to be used in micro-fracture surgery. Drilling prototypes were developed and tested to gain a better understanding of the potential and the behaviour of high-pressure water jets in conjunction with...

This thesis describes the design and implementation of a VLIW processor and associated caches based on the ρ-VEX concept. An ρ-VEX processor must be dynamically (runtime) reconfigurable to behave as a single large processor, two medium-sized processors, or four small processors. This allows a scheduler to optimize for energy and/or performance...

Several eye diseases appear in the posterior part of the eye, i.e. the retina or fundus. Retinal images therefore provide valuable information to identify eye diseases. Optical Coherence Tomography (OCT) is a 3D imaging technique that can image the retina with a resolution and depth penetration that can not be achieved by any other non-invasive...

Optical coherence tomography (OCT) probes rely on MEMS micro-scanners to provide fast and reproducible scans covering as much area as possible. A popular choice of actuators employed in this role are electrothermal bimorph actuators. They comprise of two layers of different materials which are rigidly joined together. Differential expansion...

Evidence was found for the partial explanation of firm succes from a new point of view: coherence. A positive relationship was found between coherence, a specific form of strategic fit between a core capabilities system, a way to play (strategy) and a product and service portfolio, and premium (above normal financial performance, measured by...

In order to ramp up the conversion ratios and burn-up of nuclear reactors, it is inevitable to go to tightly packed fuel rods in the reactor. These nuclear reactors with tightly packed rod-bundles are characterized by interesting flow patterns, different from the ones encountered in regular channel and pipe flows. The correct prediction and...

The goal of this thesis is to investigate the clustering effect of droplets in the water clouds. The initial motivation came from the incapability of millimeter-wave cloud radars to always detect low-level liquid water clouds. The observed discrepancy between the value of radar reflectivity factor estimated by radar measurements and the...

Non-coherent on-off keying (OOK) receivers are preferred in ultra low power (ULP) wireless devices as they consume less power when compared to receivers based on other modulation schemes. However, these devices are highly susceptible to co-channel interference (CCI). Therefore, interference cancellation (IC) techniques for ULP non-coherent OOK...

In the past two decades, dental implants have been an essential component of the public health. However, lack of a reliable and safe dental surgery imaging modality remains a major problem. Optical coherence tomography (OCT) is an interferometic optical imaging modality that is somewhat similar to B-mode ultrasound but utilizes infrared light...

After a MIMO revolution in the telecommunications world, this technology becomes increasingly popular in the radar world. The radar end-users are demanding more and more of their systems, while the targets are designed to have an as small as possible RCS, which makes them more difficult to detect. With multiple transmitters and receivers it may...
