Groenendijk, Jurre (author)With the current state-of-the-art research, exporting a NeRF to a mesh has the side effect of having to evaluate a Multi Layer Perceptron at render-time, causing a significant decrease in performance. We have found a way to use K-Means clustering to pre-compute values for this MLP, storing them in multiple octahedron maps for the GPU to fetch...bachelor thesis 2023

(author), Lesne, E.L. (author), Caviglia, A. (author)The combination of strain and electrostatic engineering in epitaxial heterostructures of ferroelectric oxides offers many possibilities for inducing new phases, complex polar topologies, and enhanced electrical properties. However, the dominant effect of substrate clamping can also limit the electromechanical response and often leaves...journal article 2022

(author), Caviglia, A. (author)In oxide heterostructures, different materials are integrated into a single artificial crystal, resulting in a breaking of inversion symmetry across the heterointerfaces. A notable example is the interface between polar and nonpolar materials, where valence discontinuities lead to otherwise inaccessible charge and spin states. This approach...journal article 2021

Reducing anionic surfactant adsorption using polyacrylate as sacrificial agent investigated by QCM-DLiu, Z. (author), Hedayati, Pegah (author), Ghatkesar, M.K. (author), Sun, Weichao (author), Onay, Hayati (author), Groenendijk, Dirk (author), van Wunnik, Johannes (author), Sudhölter, Ernst J. R. (author)Surfactant losses by adsorption to rock surfaces make surfactant-based enhanced oil recovery economically less feasible. We investigated polyacrylate (PA) as a sacrificial agent in the reduction of anionic surfactant adsorption with focus on calcite surfaces by using quartz crystal microbalance with dissipation monitoring. It was found that...journal article 2021

Groenendijk, Remi (author)Bethlehem - from exploitation to ecosystem service, is a project based on Sint Maarten in the Caribbean. The lower social classes of Sint Maarten experience trouble with their building culture, especially in combination with the reoccurring hurricanes and earthquakes. Vulnerable communities mostly rely on self or communal building, since both...master thesis 2020

van Thiel, T.C. (author), Groenendijk, D.J. (author), Caviglia, A. (author)The correlated 4d transition metal oxide SrRuO<sub>3</sub> (SRO) features an anomalous Hall effect that originates from momentum-space sources of Berry curvature and depends sensitively on the magnetization. Here, we exploit this sensitivity and realize an epitaxial extraordinary Hall balance device, consisting of two ultrathin layers of SRO,...journal article 2020

Groenendijk, Laura (author), Rezaei, J. (author), Correia, Gonçalo (author)The quality of a transit node is determined by the experience of travellers. However, the reference model for classifying the quality of a transit node, the so-called Node-Place model, does not consider this important dimension (experience). In this paper, we propose a method to add quality from a traveller's perspective to the Node-Place (NP...journal article 2018
