Mulder, Tim (author)This thesis develops a method to map the surface of an exoplanet. The problem of exoplanet mapping sounds easy to solve. Take a few photographs of an exoplanet and sew them together to create a map of the surface. The telescope required to do this is far beyond our technological capabilities. However, our current telescopes could allow us to...bachelor thesis 2022

de Zoeten, Godert (author)The world’s ever-increasing demand for energy and the inevitable depletion of the available fossil resources in the foreseeable future lead to an increasing necessity to optimize the exploitation of oil fields. The in-line liquid-liquid swirl separator is a separation method that is interesting for two reasons: It separates oil and water faster...bachelor thesis 2018

Maradiaga Rosales, Ian (author)Superconducting nanowire single-photon detectors (SNSPDs) are characterized by their quantum limited ability to accurately detect single photons, with low jitter, high detection efficiency and low dark count rate. To achieve this, the detector is cooled to 2-3K, bringing the device in a superconductive state, and is then biased with a direct...bachelor thesis 2021

de Nijs, Joost (author)The rotational velocities of stars in galaxies indicate that either Newtonian gravity breaks down on this scale, or that there is extra mass in the universe that has not been observed. The former is known as Modified Newtonian Dynamics (MOND), whereas the latter option is known as the dark matter paradigm. In this thesis a version of MOND is...bachelor thesis 2023

Kerstjens, Willem (author)Polymeric micelles have a promising future in the treatment of cancer patients, and particularly as carriers in chemotherapy. The effectiveness of the micelles can be determined when their fate in vivo is known. Radiolabeling the micelles with diagnostic radionuclides allows for determination of their biodistribution and pharmacokinetics using...bachelor thesis 2021

Levert, Tim (author)In this report, we have taken a look at three different types of trebuchets: the seesaw, the traction trebuchet or mangonel, and the counterweight trebuchet. We have created models to describe their motion by making use of Lagrangian mechanics and have compared them based on their maximum ranges. Moreover, we have also calculated a lower bound...bachelor thesis 2022

Huijsman, Robbert (author)Interest in phylogenetic trees for histories of species and DNA has spawned many problems, one of which is TreeContainment; a problem that asks whether a tree is contained within a network. The TreeContainment problem is proven to be NP-hard for general trees and networks, however it is solvable in polynomial time for networks that meet the tree...bachelor thesis 2019

Doing, Anne-Kee (author)Observing dust obscured high redshift galaxies is vital to understand the evolution of the early universe and the formation of stars and galaxies. HFLS3 is such a galaxy, and its emission spectrum can be detected at submillimeter wavelengths. With the Deep Spectroscopic High-redshift Mapper 2.0 (DESHIMA 2.0) it is pos- sible to observe these...bachelor thesis 2021

van der Enden, Kian (author)For quantum computing with superconducting qubits, fabricating transmon qubits with increased coherence time is crucial, especially in view of multi-qubit quantum processors. The fabrication process, geometries and materials used to fabricate a transmon qubit are similar to the fabrication of CPW resonators. However, due to shorter fabrication...bachelor thesis 2014

Roelvink, Y. (author)In this report, we will focus on simulating galaxy observations with the Deep Spectroscopic High-redshift Mapper (DESHIMA). To do so, we will discuss and evaluate two main parts needed to accurately perform such a simulation:<br/><br/>Firstly, we will answer the question whether Time-dependent End-to-end Model for Post-process Optimization ...bachelor thesis 2020

Reus, Jeroen (author)Metallic droplet deposition is of interest in the industry because of the potential use in additive manufacturing. This work discusses the complex phenomena involved in droplet impingement, especially the effect of temperature dependant surface tension. The volume of fluid (VOF) method is used to solve the axis-symmetric Navier-Stokes equations,...bachelor thesis 2018

van Waas, Tom (author)Non-photochemical laser-induced nucleation (NPLIN) is a process where a crystalline phase is formed out of solution by exposure to a laser beam. In NPLIN, the nucleation probability is strongly dependent on the beam intensity and weakly dependent on the wavelength. NPLIN offers a feasible alternative to energy-intensive industrial...bachelor thesis 2019

Teepe, Annick (author)In this research, the effect of Chiral Induced Spin Selectivity is studied by means of a transport calculation on a model of a chiral molecule between two gold contacts. The method consists of two main parts: optimizing the geometry of the entire system, being the molecule and the contacts, and performing the transport calculation on the system,...bachelor thesis 2019

Gajadhar, Vivek (author)Dose calculations in proton therapy need to be computed as fast as possible for successful cancer treatment planning and execution. The dose calculation algorithms that provide enough accuracy for treatment planning, takes too much time to utilise; therefore there is a need for faster alternatives. One of the alternatives is using a...bachelor thesis 2022

Al-Zubi, Kadhim (author)Quintic Duffing oscillator is considered. Amplitude-phase relations are derived using averaging theorem and perturbation methods. First The forced quintic system is studied. Stability regions are com-pared to the general case with quintic-qubic non-linearity. Numerical results show that Perturbationmethod and averaging are in agreement with each...bachelor thesis 2019

de Lange, Milou (author)Nano-carriers have the potential to be an enormous game-changer in medicinal drug delivery systems. The polymeric nano-carriers used in this study are a product of the self-assembly of amphiphilic block copolymers, a complicated process which must be understood completely to finely tune the desired morphology for drug delivery. The goal of this...bachelor thesis 2022

den Ouden, Chris (author)Preclinical SPECT systems such as the U-SPECT have been able to achieve sub-half-millimetre spatial resolution with the use of cylindrical pinhole collimators. Utilising this type of collimator comes at the cost of a reduction in the total number of detection events that take place. In order to compensate for this either the activity of the...bachelor thesis 2020

Schmits, Jeroen (author)Dipoles are all around us and the extent to which it is possible to distinguish two dipoles next to each other is a very important criterion for optical resolution. This report proposes that the resolution can be enhanced by placing a substrate with a film underneath the dipoles. This report specifically looks at the effect on the near and far...bachelor thesis 2020

Steinebach, Koen (author)The wind energy industry is growing more than ever before and wind energy as a renewable energy source has shown quite a potential over the years. Unfortunately, the power yield of a wind farm can fluctuate largely over time, which originates from fluctuating wind speed magnitudes. Convection of air, turbulence, humidity and radiation of heat are...bachelor thesis 2017
