Weiler, Marnix (author)During ‘float-out’ installation of export cables, the cable is pulled to shore while floating, supported by inflatable floaters. Understanding the hydrodynamic behaviour of these cable-floater-systems (CFS’s) is important, to be able to relate the hydraulic environment to the cable stresses and determine the maximum allowed hydraulic conditions...master thesis 2023

Hoppener, Bruce (author)Focal laser ablation is a new, promising method to treat tumors. The current focal laser ablation approach is to insert an optical fiber into the patient using rigid needles. A side effect of this approach is that during the needle insertion, tissue damage occurs. The larger the diameter of the needle, the more tissue damage. If the diameter of...master thesis 2023

van den Bergh, Michael (author)Energy harvesters subtract energy from their surroundings and convert this to electrical energy. Even though energy output is generally low, energy harvesters can offer great value by offering the possibility of self-sustaining devices, combined with the developments in low power semiconductors. Many examples can be found of applications that...master thesis 2023

van Eijk, Jordy (author)Acoustics combined with digital fabrication has been investigated for multiple years. Most research in this area has focused on the combination of acoustics and additive manufacturing. This is mainly due to the ability of this technique to create any geometry, which allows for very high absorption. However, it has the downside that additive...master thesis 2023

Kemper, Erik (author)Detection of lymph node involvement has a significant negative impact on the treatment outcome for patients with head and neck squamous-cell carcinomas (SCC). Metastatic lymph nodes can be detected with high sensitivity by 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET). However, 18F-FDG uptake is not only increased in...master thesis 2023

Sun, B. (author), Mo, J. (author), Zhang, Hemin (author), van Zeijl, H.W. (author), van Driel, W.D. (author), Zhang, Kouchi (author)The thermal-piezoresistive effect in silicon (Si) has attracted great attention toward high-performance resonant devices but still faces major challenges for harsh environment applications. Instead of using Si, this paper, for the first time, reports a thermal-piezoresistive resonator based on a silicon carbide-on-insulator (SiCOI) platform. The...conference paper 2023

Ras, Wilbert (author)Today, one of the major goals of modern astronomy is the search for other habitable worlds and the presence of life on them. Crucial in this search is the atmospheric characterisation of small, rocky planets orbiting in the habitable zone around solar type stars. The LIFE initiative will be able to perform atmospheric characterisation of a...master thesis 2022

Wang, J. (author)Varying-length cable systems are widely applied in a vast class of engineering problems which arise in industrial, civil, aerospatial, mechanical, and automotive applications. Due to external excitations, large oscillations can occur when cables are lifted up or down. This phenomenon is caused by resonance. In general, resonance is harmful, and...doctoral thesis 2022

de Winter, Jikke (author)Biosensing properties like mass, density and stiffness on a single cell level can help diagnose diseases. Mass sensing of cells and subcellular components is typically performed with resonant microstructures. Recently such microstructures were fabricated using an emerging 3D printing technique called two-photon polymerization (2PP) contrary to...master thesis 2022

Tromp, Bart (author)Confocal microscopy is often used to make three-dimensional high-resolution images of biological samples. It is done by reflecting a laser beam off of a dichroic mirror, and focusing it on a sample with the use of a microscope. This sample is treated with a fluorescent dye. The dye molecules emit light of a higher wavelength with an intensity...master thesis 2022

Rejali, R. (author)This thesis focuses on possible platforms for a bottom-up approach towards realizing and characterizing atomically assembled magnetic and electronic artificial lattices. For this, we make use of the scanning tunneling microscope (STM), which provides a local probe of the magnetic and electronic properties of the sample and allows for the atom-by...doctoral thesis 2022

Lindeman, Pim (author)Distributing power and data around a garment is a common problem in sensor enabled e-textiles, as connecting separate electronic subsystems together using connectors and wires has proven to be unreliable and cumbersome. In this work a solution is presented that will eliminate the connectors by using two pairs of short-range wireless inductive...master thesis 2022

Crossman, Genya (author)Scientific computing and applied mathematics enable the exploration of and, sometimes even, the simplification of complex systems through various optimized modeling and simulation methods. These fields create and utilize computational resources to do so. Many problems, however, are still unsolvable or very difficult to solve with current well...master thesis 2022

HUA, YUAN (author)This thesis presents a 48V-to-1V 10-level dual inductor hybrid converter (DIHC) containing 11 on-chip switches and an off-chip Gallium Nitride (GaN) switch. Thanks to the 10-level Dickson switched-capacitor (SC) circuit, most of the voltage stress will be taken over by off-chip capacitors, which reduces the voltage stress of each switch to 4.8 V...master thesis 2022

Patil, Ashutosh (author)With the increasing growth and penetration of power electronic devices in the power system, it is essential to understand the behaviour of insulation materials and systems under the varied signals that are produced with power electronic systems. These signals could be square pulses, sinusoidal or even superimposed. The high-frequency sinusoidal...master thesis 2022

Solomou, Christodoulos (author)The coastal safety of the dunes are of high importance for low laying countries (Chen et al., 2017). This is especially true for the Netherlands as it is used officially as a safety measure against flooding from extreme weather since 1984 (Rijkswaterstaat, 1989). As of current 1D modelling of the waves is an acceptable method for the Dutch coast...master thesis 2022

Al, Elise (author)We present application and developments of qMRI. We reconstructed data from the Prediva Ouderen Extentie (POE) database and calculated quantitative maps. The POE database consists of 29 7 Tesla (T) whole-brain MRI scans, including both male and female participants covering the age group between 80 and 91 years old. We used this data to extend...master thesis 2022
