van Baelen, D. (author), van Paassen, M.M. (author), Ellerbroek, Joost (author), Abbink, D.A. (author), Mulder, Max (author)Modern aircraft use a variety of fly-by-wire control devices and combine these with a flight envelope protection system to limit pilot control inputs when approaching the aircraft limits. The current research project aims to increase pilot awareness of such a protection system through the use of force feedback on the control device, i.e.,...conference paper 2021

Tillema, G.H.J. (author), Stroosma, O. (author), Miletović, I. (author), Mulder, Max (author)The Perceptual Eigenmode Distortion (PEMD), an extension to the Eigenmode Distortion (EMD), is a method for objectively evaluating simulator motion fidelity, developed over the last few years. EMD assesses how the Motion Cueing Algorithm (MCA) distorts the vehicle's perceived eigenmodes. In this paper, EMD is extended by a human perception model...conference paper 2021

(author), Mulder, Max (author)Ground-based demonstration of spatial disorientation (SD) has been recommended for military as well as commercial pilot training. Although the leans illusion is the most common form of SD, no data exist yet of an effective ground-based leans procedure for a hexapod simulator. In this paper we describe the development of such a procedure and its...conference paper 2021

Zaal, P.M.T. (author), Pool, D.M. (author), Mulder, Max (author)Linear mixed-effects models provide several benefits over more traditional statistical inference tests and are particularly useful for most human-in-the-loop tracking experiment data. However, surprisingly, mixed models are virtually not used for the analysis of tracking experiment data. This paper uses linear mixed-effects models to analyze...conference paper 2021

Reitsma, J.P. (author), van Paassen, M.M. (author), Borst, C. (author), Mulder, Max (author)In-flight non-normal events can be rather taxing for a flight crew. Numerous tasks, often competing for attention, need to be handled adequately after which, the best plan of action for the remainder of the flight needs to be determined. In the light of recent developments towards reduced crew operations, the demand for reducing workload has...conference paper 2021

Linskens, C.E. (author), Reitsma, J.P. (author), Borst, C. (author), van Paassen, M.M. (author), Mulder, Max (author)Non-normal event resolution in-flight can be challenging on the flight crew with increased time pressure, workload, stress. Other competing tasks impose a risk on flight safety and burdens the decision-making process. Pilots rely on checklists to aid in their effort, which in its state-of-the-art form are presented on the dedicated Electronic...conference paper 2021

Magni, A. (author), Calderon Gonzalez, A. (author), Mulder, I. (author)Over the past years, a growing number of local initiatives are generating solutions for societal challenges in their cities. However, the scale and complexity of these challenges force urban innovators to constantly adapt and learn, having to acquire new capabilities that will help them advance towards systemic change. In the current work, we...conference paper 2021

Aniche, Maurício (author), Mulder, F. (author), Hermans, Felienne (author)Grading large classes has become a challenging and expensive task for many universities. The Delft University of Technology (TU Delft), located in the Netherlands, has observed a large increase in student numbers over the past few years. Given the large growth of the student population, grading all the submissions results in high costs. We...conference paper 2021

Kern, Alexander (author), Mulder, Christoph (author), Hameye, Kay (author), Dong, J. (author)Magnetic force excitations in the air gap of generators can lead to tonal noise emissions of direct-drive wind turbines. Besides the magnetic circuit design, the generator air gap topology has an impact on the excited vibration modes and their frequencies, respectively. For the model-based analysis of the excited force density waves, the spatial...conference paper 2021

van der Ploeg, J.R. (author), Cleij, D. (author), Pool, D.M. (author), Mulder, Max (author), Bülthoff, Heinrich H. (author)Despite gaining popularity, the use of Motion Cueing Algorithms (MCAs) based on Model Predictive Control (MPC) remains challenging due to the required tuning of a large number of cost function parameters. This paper investigates the effects of two critical MPC cost function parameters, the lateral specific force and roll rate error weights (Way...conference paper 2020

Kolff, M.J.C. (author), Venrooij, J. (author), Pool, D.M. (author), Mulder, Max (author)Motion cueing algorithm design often involves a trade-off between priorities due to the limited workspace of the simulator. Such a trade-off requires a detailed understanding of human perception, which we do not yet have. For that reason, objective motion cueing quality metrics, based on the difference between vehicle and simulator signals,...conference paper 2020

(author)In this paper the potential of Motion Incongruence Rating (MIR) models for the optimization of Motion Cueing Algorithms (MCAs) is investigated. In a human-in-the-loop simulator experiment, two optimization-based MCAs are compared for a roundabout scenario simulated on a medium-stroke hexapod simulator. The first MCA uses standard cueing error...conference paper 2020

Piessens, Tom (author), van Paassen, M.M. (author), Mulder, Max (author)Teleoperation by definition means a deprivation of the teleoperator's senses, which can pose a handicap when operating, e.g., an UAV, in an unknown, perhaps even dynamic environment. Noticing moving obstacles in such a situation can prove to be quite difficult and the UAV runs the risk of colliding with them. Previous work designed a shared...conference paper 2020
