van Oort, Max (author), Hoogeveen, Aron (author)One of the main problems with InstanceLevel Image Retrieval in video data is that for query videos with multiple objects of the same instance, extracting features from keyframes of this query video is time consuming. This thesis aims to solve this problem by implementing a Convolutional Neural Network based approach, which significantly reduces...bachelor thesis 2022

de Graaf, John (author), Mao, Rui (author)In this thesis, the realization and qualification of an anechoic dome chamber for 5G antenna’s is discussed. As with audio, where no echoes or noise from outside is wanted when listening to music, when characterizing an antenna it must be prevented to get internal reflections or electromagnetic (EM) radiation from outside. For this reason, a...bachelor thesis 2022

Wiersma, Pelle (author), van Krieken, Roy (author)WiECG aims to create a prototype device which enable ambulance personnel to perform a 12lead ECG without wires connecting the patient to the monitor. The proposed solution consists of a transmitter and a receiver device. The transmitter transmits the measured signals, the receiver sends the measured signals to the monitor, which shows the...bachelor thesis 2022

Custers, Geert (author), Loen, Stefan (author)This report is part of the WiECG project. The goal of the WiECG project is to create a prototype device that makes it possible to perform a 12lead ECG on patients without wires from a patient to the monitor. The solution consists of a transmitter and receiver of which one is close or on the patients body and the other is connected to a monitor....bachelor thesis 2022

van Ooijen, Cas (author)This thesis is about the wave equation. The wave equation describes waves that propagate through a certain medium. The solution of the wave equation is a mathematical description of what that wave looks like. There are many fields of study where the wave equation is used to model processes that behave like travelling waves. For instance, a...bachelor thesis 2022

Glasbeek, Arnoud (author)In agricultural studies it is often important to predict the performance of genetically different plants. To make sure predictions are done well, it is necessary to make sure they are not influenced by effects of the field on which they are planted. These field effects or spatial effects are in practice often quite complicated and can be due to...bachelor thesis 2022

Ohm, Annerieke (author)Metalenz is a spinoff company of Harvard University that works on finding newer and better designs for lenses. To prevent manufacturing designs that might not work, they first want to run computer simulations on their designs. This research focuses on a possible method for these simulations using a test case as design. It turns out that the...bachelor thesis 2021

Ligthart, Liam (author)More insight has been gathered on the performance of the SPLITTER (Stationary spectrum Plus Lowrank Iterative TransmiTtance EstimatoR) algorithm as developed by Brackenhoff for denoising data gathered from observations of highredshift galaxies. By using matrix decomposition to split the gathered data into a lowrank atmosphere matrix and a...bachelor thesis 2022

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

van Niekerk, Annemijn (author)In het gebied Apeldoorn – Dieren ligt een oude spoorlijn van de Veluwsche Stoomtrein Maatschappij die op dit moment alleen nog voor toeristisch gebruik wordt geëxploiteerd. Om de bereikbaarheid van het gebied te vergroten wordt er onderzoek gedaan naar de mogelijkheid om hier een railgebonden voertuig op de introduceren. Dit leidt tot de vraag; ...bachelor thesis 2022

Victor Ryan, Victor (author)In this thesis, we present simulation studies of a nonparametric estimator, proposed by Liebscher (2005). This estimator uses a wellknown nonparametric estimator called kernel density estimator. Nonparametric estimation is used when the parametric distribution of a given dataset is unknown. This technique is then applied with an assumption...bachelor thesis 2022

van Donkelaar, Mirko (author)A code C is defined to be a set of S words, where a word is a sequence of n entries. We call S the size and n the length of the code. The entries of the code can have k different values, {0, .., (k − 1)}. Define a perfect khash code (PHC) as a code with the property that any collection of v words in the code is different at at least one index....bachelor thesis 2022

Velev, Viktor (author)In the past decade datadriven approaches have been at the core of many business and research models. In critical domains such as healthcare and banking, data privacy issues are very stringent. Synthetic tabular data is an emerging solution to privacy guarantee concerns. Generative Adversarial Networks (GANs) are one of the emerging solutions...bachelor thesis 2022

Liu, Darwin (author)The Bullet Cluster is a galaxy cluster, which is often used as evidence for dark matter [10]. In this thesis, Modified Newtonian Dynamics (MOND) is studied for various interpolation functions on a model of the Bullet<br/>Cluster. MOND is a theory proposed by Milgrom which modifies the Newtonian gravity law, such that it explains the flat...bachelor thesis 2022

Wassenaar, Vincent (author)A graph G=(V,E) is a mathematical model for a network with vertex set V and edge set E. A Random Graph model is a probabilistic graph. A Random Geometric Graph is a Random Graph were each vertex has a location in a space χ. We compare the ErdosRényi random graph, G(n,p), to the Random Geometric Graph model, RGG(n,r) where, in general we use r=c...bachelor thesis 2022

Herben, Bjarne (author)The breadth of theoretical results on efficient Markov Chain Monte Carlo (MCMC) sampling schemes on discrete spaces is slim when compared to the available theory for MCMC sampling schemes on continuous spaces. Nonetheless, in [Zan17] a simple framework to design MetropolisHastings (MH) proposal kernels that incorporate local information about...bachelor thesis 2022

van Delft, Jolijn (author)De 'grootte' van een verzameling staat in de wiskunde bekend onder de term 'kardinaliteit'. Omdat de kardinaliteit van de natuurlijke getallen niet met een eindig natuurlijk getal <i>n</i> kan worden aangetoond, is de kardinaliteit van deze verzameling uniek gedefinieerd als alefnul. Met dank aan Cantor’s bewijs voor de stelling dat de...bachelor thesis 2022

den Dulk, Timo (author)This thesis focuses on a problem formulated by Claude Shannon named the Shannon capacity. This problem is about information rate per time unit over a noisy channel. The noisy channel is here represented by a graph. We specifically focus on a class of circulant graphs that are denoted by C(n,k) with vertex set z/nz, where all vertices are...bachelor thesis 2022

van de Klok, Margot (author)Describing phylogenetic trees or networks with a polynomial is a tool to distinguish between them. In this thesis, a new polynomial for describing rooted binary internally labeled phylogenetic networks and trees is introduced based on the research of P. Liu and J. Pons et al. Two different cases are considered, one where the reticulation nodes...bachelor thesis 2022
