van Leeuwen, Marieke (author)The Oxygen Evolution Reaction (OER) is usually the go-to reaction for water-based electrolysis processes. However, this reaction can impede the performance and large-scale implementation of such processes due to its sluggish kinetics and the lack of value of its product stream. In order to boost the feasibility of electrochemical processes,...master thesis 2020

van Leeuwen, Bart (author)The emergence of connected and automated vehicles (CAVs) could have a significant impact on traffic efficiency and safety. The effects of CAVs in regular highway traffic are relatively well represented in scientific research. How these effects change in exceptional situations, such as work zones, and how the infrastructure can influence these...master thesis 2020

van Leeuwen, Bodine (author)When building a convolutional neural network, many design choices have to be made. In the case of Deepfake detection, there is no readily implementable recipe that guides these choices. This research aims to work towards understanding the effects of design choices in the case of Deepfake detection, using the Python library Keras and publicly...master thesis 2020

van Leeuwen, Jordy (author)Participant feedback in previous research indicates a need for pilot training to handle non-routine situations with automation surprises. Therefore, we tested the effectiveness of using active problem solving during training on subsequent performance while dealing with automation surprises. We simulated a glass cockpit of a general aviation...master thesis 2020

van Leeuwen, Sander (author)In the recent years the satellite industry has progressed on the subject of optical communication for use in space. With recorded speeds over 5 Gb/s it has shown to be an alternative for radio communication. In the CubeSat market this technology is new, underdeveloped, and could lead to new missions that were not possible before. As such, TNO...master thesis 2020

Langhout, T.J. (author), van Leeuwen, S.A.J. (author), Ort, C.I. (author), Volkers, W.S. (author)The Deal Analytics group of PricewaterhouseCoopers Amsterdam has requested a tool for automatising the business-to-business customer analysis. This analysis was performed manually, which left room for performance improvement. This report discusses how the a product was developed which automates the analyses After two weeks of initial research, a...bachelor thesis 2020

van Leeuwen, Lot (author)Every day we produce an extremely high amount of data and a significant portion of this data is archival data. It is an important challenge to save this data in a cheap and environmentally friendly way. The current methods to save archival data are sufficient, but improvements can be made. Synthetic DNA based data storage is a great choice to do...bachelor thesis 2020

van Leeuwen, Lars (author)With the advent of high-bandwidth non-volatile storage devices, the classical assumption that database analytics applications are bottlenecked by CPUs having to wait for slow I/O devices is being flipped around. Instead, CPUs are no longer able to decompress and deserialize the data stored in storage-focused file formats fast enough to keep up...master thesis 2019

van Leeuwen, Pauline (author)In most current dike assessments only the stationary water levels are investigated in the assessment of the stability of the inner slope, while there are differences for all kind of dikes between the stationary and transient pore water pressures and therefore in the stability. This results in a conservative probability of failure, while...master thesis 2019

van Heems, Tycho (author), van der Knaap, Arnout (author), Halfweeg, Alexander (author), van Leeuwen, Dexter (author), Veerhuis, Reginald (author)In the field of ecology there exist models that accurately represent the real world.<br/>The client, Dr. Van de Koppel, asked the team to make a game that incorporates<br/>these ecological models in the gameplay, to create a more alluring interactive<br/>experience with these models. Thus the goal of this project was to make the<br/>game...bachelor thesis 2019

van Leeuwen, Lotta (author)A hydrogen fuel cell scooter was tested for the first time to alternatively drive, power electric appliances (Vehicle-to-Load, V2L) and power the grid (Vehicle-to-Grid, V2G). Performance of the scooter is known to rely mainly on the fuel cell stack, and fuel cell degradation depends on the operating conditions. This study aimed to provide...master thesis 2018

Simons, Ascha (author), Wauben, Chris (author), Pije, Lars (author), van Leeuwen, Niels (author)Two polluted Ghanaian lagoons are investigated and possible engineering solutions are suggested and researched.<br/>The first lagoon is the Sakumo lagoon, located between Accra and Tema. This lagoon is connected to the sea through a small culvert, which enables a limited amount of water exchange. Since a few years, fishermen have been unable to...student report 2018

van Leeuwen, Stefan (author)The heat pipe assisted annealing project is a project in which Tata Steel, TU Delft and Drever International work together to develop a continuous annealing line with heat pipes. In an annealing line cold rolled steel is heated to 973 K and cooled down again to change the properties of the steel. In the heat pipe assisted annealing project the...master thesis 2018

van Leeuwen, Michel (author)Current literature on the usage of the experience curve in a societal cost-benefit analysis is lacking. It is unclear how the experience curve should be used in a societal cost benefit analysis and how large the effect or added value is. This thesis uses a case study to analyses effects of the experience curve on a societal cost benefit analysis...master thesis 2018

van Leeuwen, Simon (author)All ships rely on many on board systems to reliably complete their missions (e.g. transporting containers, laying pipes or protecting the seas). However, for many of these ships, the detailed design of these systems is put off until the later stages of the design. For most ships, this will create no problems. However, for those complex vessels...master thesis 2017

van Leeuwen, Bodine (author)In 1969, the theorem of Reichert was formulated. Since then, two proofs have been found, both by Z. Jiang and Malcolm C. Smith, one of which in collaboration with Sara Y. Zhang. These proofs are based on the transfer functions of the electrical networks. <br/>The aim of this paper is to work toward a proof based on graph theory, linear algebra...bachelor thesis 2017
