de Heus, Yfke (author)The COVID19 pandemic has infected millions of people worldwide and many countries have suffered one of the worst recessions in history. While there are numerous studies of mathematical models trying to predict and understand the evolution of the pandemic, research into the effects of the coronavirus on the economy remained in the background....bachelor thesis 2022

Kirchner, Joris (author)Neural network is an active research field which involves many different (unsolved) issues, for example, different types of configuration of the network architectures, training strategies, etc. Amongst these active issues, the choice of loss (or cost) functions plays an important role in how a neural network model is to be optimized (trained)...bachelor thesis 2022

Abutan, Lisanne (author)Interference of light can be used to determine the concentration of a gas, called gas sensing. The absorption of the light by the gas molecules is measured based on the phase change of the light. In this report, a hollow core photonic crystal fiber is treated. The gas sample is inserted into the hollow core. Photonic crystal fibers possess the...bachelor thesis 2022

Arens, Patricia (author)In the last decades there has been an increasing interest in computing the local strain at the atomic scale of materials. By knowing aspects of the local strain in a lattice, one has information about measurements of distortions of lattice parameters concerning shifts, deformations and defects computed with respect to a smooth, defectfree...bachelor thesis 2022

Claes, Joep (author)Random walks have been applied in a many different fields for a long time. More recently, classical random walks are being used in wide variety of computer algorithms used to solve complex computational problems like 2SAT, 3SAT and the estimation of the volume of complex bodies. In this thesis we look into the quantum version of the familiar...bachelor thesis 2022

de Groot, Dayo (author)In deze scriptie gaan we twee wiskundige objecten onderzoeken, het ultrafilter en de ultramacht. Zodra je in de wiskunde een nieuw object hebt bedacht zijn de eerste twee vragen die je stelt altijd 1) bestaat het? en 2) Als het bestaat, is het dan uniek, of zijn er meerdere? Nou is dat voor een ultrafilter relatief makkelijk te beantwoorden. In...bachelor thesis 2022

van Vroonhoven, Thomas (author)This project models collective cell migration and differentiation as part of a wound healing process. The hybrid mathematical model used in this project consists of an agentbased model for the cells combined with a system of coupled partial differential equations for two forms of the growth factor molecule TGFbeta. The model is implemented in...bachelor thesis 2022

Wanningen, Nicky (author)For scaling up the qubits in silicon quantum computers, it is vital to determine crosstalk effects that can lower the fidelity of the computer. <br/>In this computational project, we examine singlequbit gatefidelities in the presence of crosstalk for uncoupled spin qubits that are driven with Xgates via electron dipole spin resonance (EDSR)....bachelor thesis 2022

van Prooijen, Birgit (author)While the Minimum Euclidean Distance detection is known to be optimal for channels affected by Gaussian noise, it has been shown that Minimum Pearson Distance detection (MPD) may perform better when the channel is also affected by an unknown offset, though for a good performance some adaptations for classical binary block codes are necessary. It...bachelor thesis 2022

Sikkens, Duuk (author)Deze scriptie gaat over βN. Wat specifieker: ze gaat over onvergelijkbare elementen in de RudinKeislerorde op βN. βN is een topologische ruimte, het is de ČechStonecompactificatie van de natuurlijke getallen. Er kan over βN echter ook op een meer verzamelingtheoretische manier worden nagedacht, namelijk als de familie van alle ultrafilters op...bachelor thesis 2022

Capel, Judith (author)Nowadays, we produce an enormous amount of data and all this data needs to be stored somewhere. In order to store all this data in an efficient and environmentally friendly way, solutions need to be found. A storage technique that has great potential to be a solution is synthetic DNA based storage.<br/>A DNAstrand is made up of a sequence of...bachelor thesis 2022

Chang, Jakka (author)The Generalized Gamma Distribution (GGD) is a threeparameter distribution with desirable properties. For certain values of the parameters, the GGD can reduce to the gamma, exponential and lognormal distribution, among others. This makes it a flexible distribution that can be used in various scenarios. The problem with implementation of the GGD...bachelor thesis 2022

Geerts, Nathan (author)In this report, a transformer based deep learning proton dose calculation algorithm called Dose Transformer Algorithm (DoTA) is described. This model learns to predict proton dose distributions by being trained with Monte Carlo generated data. Monte Carlo is the golden standard of proton dose calculation because it is very accurate, but it has...bachelor thesis 2022

Swart, Céline (author)The transverse flute can be studied on many aspects. In this thesis the sound waves that can be generated inside the flute are studied on their shape and frequencies. To achieve this, two mathematical models of the sound waves inside a flute are developed. To develop these models, solutions to the second dimensional wave equation are calculated...bachelor thesis 2022

Swinkels, Bart (author)The "Number Hides Game" (NHG) is 2player game played on a board that consists of a row of p consecutive coins. Player I and player II simultaneously choose subsets of m and n consecutive coins respectively. Player II pays the number of coins that lie in the intersection of the subsets to player I. This thesis introduces basic knowledge from the...bachelor thesis 2022

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

Vermeer, Wiggert (author)Synchronisation refers to the tendency of coupled oscillators to move in phase with one another over time, departing from their own natural frequency. This phenomenon occurs in almost all branches of science, engineering, and social life. Synchronisation is a well understood concept in classical mechanics. Quantum synchronisation involves...bachelor thesis 2022

Blanken, Sweder (author)In the near future, nextgeneration telescopes will be able to observe Earthlike exoplanets illuminated by their parent stars for long periods of time. As the distance between exoplanet and observer is enormous, exoplanets will only make up a pixel on our image. However, the observed intensity of this pixel will fluctuate over time as the...bachelor thesis 2022

de Graaff, Ruben (author), Fontenai, Nicolas (author)In 2019 the European Aviation Environmental Report stated showed a relative increase in CO2 emissions of 16% compared to 2005 to 2017. It also stated that an increase of 42% is expected according to current models. Aviation is thus a big sector of the global warming problem. The solution to this is to go full electric. There are already more...bachelor thesis 2022
