de Vries, Chiel (author)To validate the quality of software, test cases are used. These test cases are often manually-written, which is labor-intensive. To avoid this problem, automated software testing was invented. Search-based software testing is a useful tool for developers to automatically generate test cases. However, improvements are still needed to create test...bachelor thesis 2020

de Vries, M.M. (author)We start our introduction to DNA matching with the direct match case: we find DNA at a crime scene and find a direct match with a member of our database. To measure the strength of our case against the match, we use likelihoodratios. We differentiate between two different situations: the probable cause case, where we already suspect our match and...bachelor thesis 2016

Rietveld, Jip (author), de Vries, Rolf (author), de Boer, Jaap (author), Hondelink, Dieuwer (author)Amsterdam Airport Schiphol has 5 runways, each of which can be used for take-off or landing of aeroplanes. The weather heavily influences which runway configuration air traffic control might pick. Airport Forecasting Service (AFOS) predicts which configuration of runways works most efficiently given a set of expected weather conditions and the...bachelor thesis 2019

Uljee, Jasper (author), de Vries, Yorick (author)Accurate diagnosis and treatment of patients infected with multiple strains of a pathogen is a challenging task. The use of whole genome sequencing techniques provide high potential to give proper insight into the microbial composition of human metagenomic samples. Distinguishing multiple strains of a certain species is difficult due to the high...bachelor thesis 2018

de Vries, Bram (author)While continuous integration has already been proven to positively affect software development, little is known about how it should be implemented based on project context. This paper investigates how CI pipelines are configured by analysing data mined from software projects on GitHub. This re- search has shown the continued rise of the CI plat-...bachelor thesis 2023

Weustink, C.A. (author), de Vries, J.W. (author)The most promising method for acoustic feedback control in public address systems is adaptive feedback cancellation (AFC). This approach is based on making an estimation of the room impulse response, which is used to subtract an estimate of the feedback from the microphone signal. A postfilter is often used to improve the performance of such an...bachelor thesis 2020

de Vries, Lisa (author)We live in an online world: we date online, we do business online and we communicate online. To make sure this happens securely, almost all transferred data is encrypted by cryptosystems. This paper focuses on one of these: the knapsack cryptosystem of Merkle and Hellman, which relies on the hardness of solving the knapsack problem (1978). In...bachelor thesis 2021

de Vries, Olaf (author)In this work, Clebsch-Gordan coefficients are studied from both a quantum mechanical and a mathematical perspective. In quantum mechanics, Clebsch-Gordan coefficients arise when two quantum systems with a certain angular momentum are combined and the total angular momentum is to be found. We start by discussing the relevant postulates of quantum...bachelor thesis 2021

van der Wal, R. (author), Kuipers, M.E. (author), Miljak, L. (author), de Vries, J.N. (author)Robots play an increasingly large role in society and some material already exists that allows children to program robots in elementary school. However, this material often neglects the interactive capabilities of modern robots. The aim of this project is to teach children how to write interactive programs for a robot. For this purpose, a NAO...bachelor thesis 2017

de Vries, Ate-Jan (author)Non-Euclidean spaces are spaces that do not satisfy all of Euclid’s postulates. An example of such a space is hyperbolic space. In this paper, a method is discussed to draw a tessellation of hyperbolic space in a manner that fits with the virtual reality game "Holonomy", a game which takes place in hyperbolic space. The main result shows that...bachelor thesis 2023

van der Stel, Paul (author), de Vries, Caren (author), Lemaire, Chris (author), van Tartwijk, Maarten (author), Baartman, Wesley (author)For this project, JEM-id tasked us with creating a proof of concept of a new online auction in the form of a web application for Royal FloraHolland. JEM-id is a software company operating in the agricultural domain.<br/>The pre-existing digital auction is not available as a web application and has generated technical debt over the past twenty...bachelor thesis 2019

Yildiz, Hüsna (author), de Vries, Marten (author), Öztürkoglu, Emirhan (author)This thesis describes the design of a low-cost class-S power quality analyzer based on a Raspberry Pi 4. Capable of detecting power frequency, magnitude, voltage dips and swells, harmonics, and total harmonic distortion, the project consists of four main components: the communication protocol, the interface, the algorithms for power quality...bachelor thesis 2024

de Vries, Niels (author)Bulk materials such as iron ore transported by bulk carriers are commonly unloaded by the use of grabs. The unloading process is time consuming and increasing the unloading capacity is of big importance for terminals. A validated co-simulation developed by the TU Delft in cooperation with Nemag enables to test grabs in the virtual environment....master thesis 2020

de Vries, Celia (author)This graduation project focusses on the circular economy as a broader topic and stimulating specific circular behaviour within adolescents as a scope. The municipality has a specific division called Rotterdam Circulair tasked with the assignment of accelerating the city of Rotterdam towards a circular economy. The designer of this project has...master thesis 2020

de Vries, Laura (author)Over the last years the Netherlands has often had to deal with droughts and water shortages during summer. This problem is caused by long periods without rain but with high evaporation rates and is enhanced by groundwater extraction for drinking water. Due to climate change, these droughts are expected to occur more often and become more severe....master thesis 2021

de Vries, Maaike (author)In 2015, the UN climate agreement was signed by the Netherlands, which has the central aim to “strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius” (UNFCCC, 2018)....master thesis 2019

de Vries, Jelle (author)Mobile soft robots show great potential for exploration of unknown and hard to navigate environments. Sadly, most of these robots are currently being held back by their power sources and control systems. These components, which are usually quite heavy and bulky, need to be integrated before mobile soft robots can cut their tethers and explore...master thesis 2021

de Vries, Wytze (author)This design report discusses the embodiment design of a more efficient frying pan for gas powered stoves in commercial kitchens, to see if a potential market entry is feasible, viable and desirable. Conventional pans have a thermal efficiency of roughly 25%. This means that only 25% of the heat coming from the combusted gas is used for cooking....master thesis 2023

de Vries, Ismay (author)This thesis investigates different ways in which the productivity of a one-way bottling and packaging production line can be increased. This is done by comparing different configurations regarding machine capacities, machine reliability and buffer capacities with each other. This is done with both the use of a generic model and a case study. The...master thesis 2020

de Vries, Coen (author)Since the Industrial Revolution, fossil fuels have played, and continue to play, a dominant role in global energy systems, and thereby in the social, economic and technological developments worldwide. Unfortunately, these energy sources have their negative side-effects: local air pollution and global CO2-emission. The latter has never been this...master thesis 2021
