From CTA to 3D modelling: A computational framework for morphometrical assessment and biomechanical analysis of atherosclerotic carotid arteries

Background: Ischemic stroke is a major cause of death worldwide. Atherosclerosis in the carotid arteries is an established predictor of these events. Ideally, patient-specific prevention plans can be developed that target advanced plaque development prior to events. Morphometry of advanced calcified plaque phenotypes can be assessed through...

Sensor Integration in PV Devices: State of the Art and Future Opportunities

The on-field performance and lifespan of PV modules are affected by the interaction of numerous parameters, among which temperature, strain, and humidity. Among these parameters, only temperature is occasionally measured in PV installations, and such monitoring is often external to the module. This limits its use and does not provide accurate...

The effect of the yield to tensile strength ratio on the stress field in stress/strain concentrations around holes in steel structures

The aim of this thesis is to determine the influence of the Y/T, yield to tensile strength, ratio on the stress fields of high strength steels. This is relevant to the offshore industry as regulations restrict the use of steels with a high yield to tensile strength ratio, which is a characteristic of high­-strength and<br/>ultra high­-strength...

Micro-scale effects of stylolite orientation on the motion of tensile failure: A study analyzing strain fields of stylolite limestones using Particle Image Velocimetry

Many laboratory tests of samples where the rock fractures are based on<br/>meso-scale (cm) characterization of effective ‘intact’ strength parameters neglecting the microstructure effects. Understanding fracturing processes at<br/>micro-scale (mm) will require models with microstructure data. However,<br/>data is lacking on micro-scale.<br/...

Knitted Smart Textile Sensors: Integrating technlogy into garments by using knitting

Nowadays, people are using more and more technology to measure their body performances like smart watches, heart rate sensors etc. These are all separate devices. What if it were possible to integrate these into something we wear daily. Textiles are something everyone wears daily. It is a promising medium to integrate electronics in. Especially...

Quantum Enhanced Accelerometer using NV Centres in Diamond

Silicon accelerometers used in the automotive industry should be improved in resolution and accuracy. Exploiting quantum effects in diamond to improve sensing accuracy is a popular technique for nanoscale sensing applications. This thesis will present a new design concept for an accelerometer using these quantum effects for sensing on a...

The emergence of dissipation dilution: in doubly clamped nanomechanical resonators

The goal of the research described in this thesis was to investigate the basis of dissipation dilution as well as make it comprehensible. In the written literature we could find that the kinetic energy of an oscillating beam is stored into two types of potential energy~\cite{Kippenberg, Kotthaus}. A dissipative bending component and a...

Fatigue Modelling With A Two-Dimensional Spring Network

A random periodic two-dimensional spring network us built using a Poisson disk distribution and computing the Delaunay triangulation of the centers of the disks. The edges of the network represent springs that obey Hooke’s law with an adjustment on the spring constant. The adjustment allows spring to soften and to break. The two-dimensional...

The development of a Statistical Shape- and Finite Element-Model of the human pelvis to analyse the performance of current acetabular implants and validate the concept of a new deformable design

Background: Patients who suffer from acetabular bone defects are often subjected to a decreased mobility and a loss of independence. To treat these bone defects, standard hemispherical acetabular implants offer in most cases the solution. However, when these defects are large, a custom triflange acetabular implant is needed. Although this type...

Monitoring strain in rolling element bearings using fiber Bragg grating sensors

Using Fiber Bragg Grating (FBG) sensors in rolling element bearings is a novel way of monitoring bearings. During prototype testing, differences between sensor readouts were observed, leading to the research question: “What causes the observed differences in the strain distribution from sensor to sensor in a rolling element bearing equipped with...

Load Estimation and Uncertainty Analysis Based on Strain Measurement With Application to Load Sensing Bearing

Rapid growth in automotive sector and stringent safety requirements have led to the need for more sophisticated feedback mechanisms for the vehicle systems. One of the major breakthrough is anticipated with the use of estimated loads with help of a Load Sensing Bearing. Load Sensing Bearing is a concept in which strain is measured on a hub...
