Groen, Vincent (author)The current state-of-the-art image alignment techniques and their input parameters are often unintuitive to those without the required background knowledge.<br/>This work aims to provide users with a graphical user interface through which they can intuitively influence the parameters and results of the algorithm by excluding certain areas from...bachelor thesis 2022

Groen, Stan (author)This thesis investigates the behaviour of one-dimensional blood flow in the human arterial tree. It focuses on modeling the change in velocity, cross-sectional area, and concentration. The equations governing this flow are derived using the physical laws of conservation of mass, conservation of momentum, and the<br/>advection-diffusion equation....bachelor thesis 2023

Groen, Arthur (author)In dit verslag worden drie noties van eindigheid van een verzameling gedefinieerd.<br/>Een verzameling is eindig wanneer er een bijectie bestaat tussen de verzameling en een natuurlijk getal. Uiteraard worden eerst de natuurlijke getallen gedefinieerd.<br/>Een verzameling is surjectie-eindig als iedere surjectieve functie met als domein en...bachelor thesis 2018

(author)With more flexible and large-scale learning environments, new design requirements for games emerge. Massive Open Online Courses (MOOCs) are one of the most important innovations in the learning field. Still, it is a challenge to motivate learners and to keep them motivated in such huge learning environments. To address this challenge, we...book chapter 2016

Groen, M. (author), Van Schravendijk, M. (author), Barrett, R. (author), Vos, R. (author)The dynamic response of a new class of flight control actuators that rely on post-buckled recompressed (PBP) piezoelectric elements is investigated. While past research has proven that PBP actuators are capable of generating deflections three times higher than conventional bimorph actuators, this paper quantifies the work output and power...conference paper 2009

Bouwhuis, Twan (author), Verwijmeren, Joris (author), Pijls, Ruth (author), Groen, Brenda (author)Background and aim - Police interrogations tend to be very stressful. This comes at the expense of the effectiveness of interrogations as stressed suspects and witnesses provide less extensive and accurate statements. A more comfortable environment probably leads to more effective interrogations for all persons involved. The aim of this research...conference paper 2022

(author)Automatic quantification of carotid artery plaque composition is important in the development of methods that distinguish vulnerable from stable plaques. MRI has shown to be capable of imaging different components noninvasively. We present a new plaque classification method which uses 3D registration of histology data with ex vivo MRI data,...conference paper 2011

Wang, H. (author), Groen, F.H. (author), Pereira, S.F. (author), Braat, J.J.M. (author)We present an analysis of the reading capability of a novel optical pickup consisting of a single-mode and a multi-mode rectangular waveguide. According to the simulations, if one has prior information about the structure of the disk, superresolution readout could be achieved. The proposed system has the advantage to be compact and should be...conference paper 2004

De Winkel, K.N. (author), Correia Gracio, B.J. (author), Groen, E.L. (author), Werkhoven, P. (author)Knowledge of human motion perception can be applied in the optimization of motion cueing algorithms. In the past it has been shown that some discrepancies between the amplitude or phase of a visual and inertial cue go unnoticed. These acceptable discrepancies are referred to as coherence zones. In the present experiment we investigate whether a...conference paper 2010

(author)BiFeO<sub>3</sub> is a multiferroic material with the perovskite structure which is promising for use in sensors and transducers. Single phase production of BiFeO<sub>3</sub> remains a challenge, however. In this study, the optimal calcination temperature to obtain close to single phase powder was determined to be 750°C. The sintering...conference paper 2019

In the current experiment, we tested how pilots reacted to using such a method, which featured the mnemonic COOL: Calm down – Observe – Outline – Lead. Using a motion-based simulator outfitted with a non-linear aerodynamic model of a small...conference paper 2019
