Smith, Caitlin (author), Shepherd, Jami (author), Renaud, G.G.J. (author), van Wijk, Kasper (author)We present a technique called photoacoustic vector-flow (PAVF) to quantify the speed and direction of flowing optical absorbers at each pixel from acoustic-resolution PA images. By varying the receiving angle at each pixel in post-processing, we obtain multiple estimates of the phase difference between consecutive frames. These are used to...journal article 2024

van Wijk, Thijs (author)In this work we investigate two boundary-value control algorithms for the heat equation on the finite interval. The algorithms we discuss here are based on the unified transform method (UTM), a method invented by A. S. Fokas to solve boundary value problems of partial differential equations. We first inspect the boundary-value control algorithm...master thesis 2023

van Wijk, Rijk (author)Forensics is the art of gathering evidence, which for electronics amounts to accurately recovering data. Often, this can only be archived with state-of-the-art hacking techniques.<br/>However, replicating state-of-the-art research in hardware security can be difficult, due to the large number of components and connections. To counter this, a...master thesis 2023

(author), Westerweel, J. (author), Suijker, W. (author), van Wijk, R. (author)The principal aim of the work presented here is to investigate and demonstrate that a forward tilted rowing blade would result in a more efficient and effective motion of the blade through the water that would result in a higher boat speed when an equal input power is provided. A 1:5 scaled rowing boat is used to determine the performance of...journal article 2023

van den Heuvel, D. (author), van Wijk, Martin (author)The chapter contains a report of the ongoing research into queer voices and architecture at the Nieuwe Instituut in Rotterdam, which holds the National Collection of Dutch Architecture and Urban Planning. After introducing the National Collection, the authors critically examine how its internal power dynamics and mechanisms privilege certain...book chapter 2023

van der Roest, E. (author), Bol, Ron (author), Fens, T.W. (author), van Wijk, A.J.M. (author)Recovery of heat from electrolysers is potentially interesting to increase the total system efficiency, reduce CO<sub>2</sub> emissions, and increase the economic feasibility of both hydrogen and heat production. This study examines different designs for the utilisation of (waste) heat from a 2.5 MW<sub>el</sub> polymer electrolyte membrane ...journal article 2023

van Wijk, Christine (author)Technological developments in the field of digitalisation, automation and sustainability are moving fast in road transport. Without innovative developments in the railway sector, the competitive position of the sector will deteriorate. For this reason, the rail sector must innovate at a faster pace to remain competitive. Also, it is expected...master thesis 2022

van Wijk, Marco (author)In order to combat the global climate crisis, our energy provision needs to be decarbonized. One of the potential methods that can help is Green Hydrogen Energy Storage (GHES). GHES is a complex technology/energy carrier combination. It comprises of a conversion process of renewable electricity to hydrogen to then be used for conversion back to...master thesis 2022

van Wijk, J. M. (author), de Hoog, E. (author), Talmon, A.M. (author), van Rhee, C. (author)The hydraulic transport of sediments in sediment–water multiphase mixtures is an important process in nature and many industrial applications. The flows are characterized by complex transient phenomena, in which the overall system scale and the particle scale are equally important. Experimental research into dense mixture flows is focused on...journal article 2022

de Hoog, E. (author), van Wijk, J. M. (author), Talmon, A.M. (author), van Rhee, C. (author)Density wave amplification in hydraulic transport pipelines forms a high risk to operational continuity, as density waves can lead to system blockages or centrifugal pump drive failures. Recent experimental research, in pipelines which contain long vertical sections, has shown that density waves can amplify at velocities far exceeding the...journal article 2022

van Wijk, Robert (author), Lazcano, Andrea Michelle Rios (author), Akutain, Xabier Carrera (author), Shyrokau, B. (author)Modern Advanced Driver Assistance Systems (ADAS) are limited in their ability to consider the driver's intention, resulting in unnatural guidance and low customer acceptance. In this research, we focus on a novel data-driven approach to predict driver steering torque. In particular, driver behavior is modeled by learning the parameters of a...journal article 2022

van Wijk, Robert (author)Current commercial Driver Steering Assistance Systems (DSAS) focus on path-tracking performance without taking into account driver intentions. Improved driver-automation interaction can be achieved by sharing vehicle lateral control through torques. Furthermore, integrating a driver steering-torque model allows to better match driver intentions....master thesis 2021

van Wijk, Edward (author)The goal of this thesis is to look into the possibilities of making origami neutrally stable. This is wanted because the inherent stiffness of origami mechanisms introduces unwanted artifacts such as a higher actuation force, and the mechanism not following the theoretical kinematics. By making an origami mechanism neutrally stable the inherent...master thesis 2021

van Wijk, Paul (author)Web-based interaction logging is an important concept for understanding user behavior on web-pages. LogUI is a powerful modern framework for logging a user's interactions. Integrating such a framework in web-pages requires the construction of configuration objects to define selectors that indicate which elements on a web-page should be under...bachelor thesis 2021

van Wijk, Adriaan (author)The Ocean Cleanup is an NGO founded in 2013, with the aim to rid the world’s oceans of plastic by 2040. Collecting this plastic however begs the question: ‘What to do with this waste after it has left the ocean?’To answer this question, first, it is important to look at the material. In my research, I defined the following tiers of ocean plastic...master thesis 2021
