Warm optical design and injection systemGarreau, Germain (author), Bigioli, Azzurra (author), Laugier, Romain (author), Raskin, Gert (author), Morren, Johan (author), Berger, Jean Philippe (author), Dandumont, Colin (author), Goldsmith, Harry-Dean Kenchington (author), Loicq, J.J.D. (author)Asgard/NOTT (previously Hi-5) is a European Research Council (ERC)-funded project hosted at KU Leuven and a new visitor instrument for the Very Large Telescope Interferometer (VLTI). Its primary goal is to image the snow line region around young stars using nulling interferometry in the L′-band (3.5 to 4.0) μm, where the contrast between...journal article 2024

van der Slikke, R.M.A. (author), de Leeuw, Arie-Willem (author), de Rooij, Aleid (author), Berger, M.A.M. (author)Within rehabilitation, there is a great need for a simple method to monitor wheelchair use, especially whether it is active or passive. For this purpose, an existing measurement technique was extended with a method for detecting self- or attendant-pushed wheelchair propulsion. The aim of this study was to validate this new detection method by...journal article 2024

van Dijk, M.P. (author), Hoozemans, Marco J.M. (author), Berger, M.A.M. (author), Veeger, H.E.J. (author)In wheelchair sports, there is an increasing need to monitor mechanical power in the field. When rolling resistance is known, inertial measurement units (IMUs) can be used to determine mechanical power. However, upper body (i.e., trunk) motion affects the mass distribution between the small front and large rear wheels, thus affecting rolling...journal article 2024

(author), Wimmler, Marie Christin (author), Grimm, Volker (author)Despite the increasing use of standards for documenting and testing agent-based models (ABMs) and sharing of open access code, most ABMs are still developed from scratch. This is not only inefficient, but also leads to ad hoc and often inconsistent implementations of the same theories in computational code and delays progress in the...journal article 2024

van Dijk, M.P. (author), Hoozemans, Marco J.M. (author), Berger, M.A.M. (author), Veeger, H.E.J. (author)An important performance determinant in wheelchair sports is the power exchanged between the athlete-wheelchair combination and the environment, in short, mechanical power. Inertial measurement units (IMUs) might be used to estimate the exchanged mechanical power during wheelchair sports practice. However, to validly apply IMUs for mechanical...journal article 2024

Gareth (author), Sun, Zhanli (author), Berger, Thomas (author)There has so far been no shared understanding of validity in agent-based simulation. We here conceptualise validation as systematically substantiating the premises on which conclusions from simulation analysis for a particular modelling context are built. Given such a systematic perspective, validity of agent-based models cannot be ensured if...journal article 2023
