Bot, Chris (author), de Groot, Arthur (author), de Spirlet, Aurore (author)60 million people around the world have epilepsy, which is a neurological disorder that severely impacts their day to day life negatively. Currently available methods to reduce the effects of epilepsy are either ineffective or require expensive and invasive surgery. A new method has been found that can suppress epilepsy without the need of...bachelor thesis 2022

van Heteren, Mauries (author), Dijkstra, Jonathan (author)In this thesis, the design of a frequency analysis system for conveyor belt weighing systems is designed. The objective of the thesis is to detect a change in resonance frequency, caused by a change of pressure applied to a sensor. The design features a resolution of 10 000 discrete frequency levels in a bandwidth of 0.5 MHz. Noise division of a...bachelor thesis 2020

Badier, Timon (author)Artificial Intelligence in the form of neural networks is becoming wide spread. This report focuses on a specific form of neural networks, Simplicial Neural Networks. After presenting their advantages and how they were implemented in Python by using the code of [1], they are tested in 2 experiments to explore their applicability in solving...bachelor thesis 2021

Mulder, Jasper (author)In this thesis, the repetition code for bit flip errors is examined. Based the stabilizer measurements outcome of a run of the repetition code, one does not know exactly which errors have occurred. Statistics can be used to estimate the probability of all possible error events. This probability estimation is investigated for simulated data...bachelor thesis 2022

Wong, Jing Jing (author)This research consists of two applications of image processing, namely, image compression and image denoising. Image compression aims to reduce the size of an image without losing too many features. This is often used to store a large number of images such as fingerprints. Denoising is a technique for removing noise from an image while...bachelor thesis 2022

Swinkels, Bart (author)The "Number Hides Game" (NHG) is 2-player 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

Klomp, Levi (author)The purpose of this study is to define and estimate multivariate statistic models, inspired by the data of the Cosmic Microwave Background Radiation, and apply those models to self-simulated data. Two distinct models are constructed using random fields, which include a set of parameters, structural covariance among random variables and a...bachelor thesis 2021

Hajer, Wouter (author)Over the past century various different discrepancies in the expected and observed behaviour of galaxies and galaxy clusters were found. Together this is called the missing mass problem and the most well known theory trying to explain these differences states that there is additional undetectable mass in the form of dark matter. Modified...bachelor thesis 2022

Bogaert, Bonne (author), Otter, Mirthe (author), Mijjer, Luuk (author)This report details the design and development of an agar/NaCl gel-like tissue phantom mimicking the electrical properties of wet human skin. The skin phantom provides a reliable, reproducible testing ground for dry-contact polydimethylsiloxane (CNT/PDMS) electrodes, with the aim of recording electroencephalograms (EEGs) and stimulating brain...bachelor thesis 2022

de Waaij, Yvar (author)Deze scriptie beschrijft een onderzoek naar de toepasbaarheid van verschillende pop-up fietspaden. Dit zijn fietspaden welke in zeer korte tijd kunnen worden aangelegd en in een latere fase definitief worden gerealiseerd of weer verdwijnen uit het straatbeeld. Aangezien pop-up fietspaden in de meeste gevallen op dezelfde rij loper liggen als...bachelor thesis 2022

Cohen, Daniel (author)In probability theory, Lp spaces for p > 0 together with the topology of conver-<br/>gence in probability have been widely applied. However, in that case we restrict<br/>ourselves to only a part of all the measurable functions and to an underlying prob-<br/>ability space. One of the main aims of this thesis is to generalize this concept to<br...bachelor thesis 2022

Korevaar, Matthijs (author), Hoogland, Lars (author)One of the main problems with Instance-level Image Retrieval in video data is that for longer query videos or large amount of image queries, comparing all of the query images to every extracted frame is time-inefficient. This thesis aims to solve this problem by implementing Nearest Neighbour Search (NNS) algorithms and data compression methods,...bachelor thesis 2022

Xu, Bo Wen (author), Kamminga, Arjan (author)A new antenna measurement setup, the Antenna Dome, is being developed, which can provide real time antenna and beamformer measurements. In order to be able to validate this setup, an existing beamforming system will be will be extensively studied and characterized. Multiple measurement setups will be used, providing multiple measured...bachelor thesis 2022

Veenman, Victor (author)Due to human advancement in recent centuries, extinction rates of animals and plants around the earth have greatly risen. Conservation biology, the study of conservation of nature and earth’s biodiversity, aims to protect species from these increasing extinction rates.<br/>Phylogenetic diversity is a measure for biodiversity that can help in...bachelor thesis 2022

Wijker, Alyssa (author)In this report a new approach to (forensic) handwriting analysis is presented; score-based likelihood ratio (SLR) systems are employed and their quality of performance is studied. These systems compare elements of handwriting based on their characteristics and give an insight into the degree of uncertainty of the statement that two writings have...bachelor thesis 2022

van der Niet, Sjoerd (author)The Curie-Weiss model is a simplification of the Ising model to show the existence of a phase transition for ferromagnetism. In this thesis, we study the behaviour of sums of these dependent variables. We prove in general that under the appropriate assumptions, we can still conclude a version of the Law of Large Numbers. We also find that if...bachelor thesis 2022

Tran, Minh Tâm Kevin (author), Yang, Ming Da (author), van Nieuwburg, William (author), van Spreuwel, Bram (author)A 1:5 scaled rowing boat had been designed by a previous research group to determine the performance of rowing blades with different sizes and blade angles. In this research modifications were done to allow more control of the rowing motion. The aim of this study is to assess whether an angled oar blade can reach faster speeds with the same...bachelor thesis 2022
