Mulder, W.A. (author)Multi-parameter inversion of linear systems appears in many problems. The focus here is on isotropic elastic iterative reverse-time migration for three position-dependent subsurface model parameters, which amounts to data fitting of processed seismic data with synthetics from the Born approximation of the elastic wave equation. In that case, the...conference paper 2021

Mulder, W.A. (author)Recently introduced non-reflecting boundary conditions are numerically exact: the solution on a given domain is the same as a subset of one on an enlarged domain where boundary reflections do not have time to reach the original domain. In 1D with second- or higher-order finite differences, a recurrence relation based on translation invariance...conference paper 2021

Buckenmayer, M.B. (author), Gonçalves, M. (author), Mulder, I. (author)Social innovations are promising to tackle today's complex global challenges, especially when they scale, leading to a higher impact, which can generate asocietal transformation. The current work elaborates on scaling deep, a specific scaling strategy aiming to shift cultural values, mindsets and beliefs. However, applying this strategy in...conference paper 2021

Buckenmayer, M.B. (author), Gonçalves, M. (author), Mulder, I. (author)“Off to new shores!” is a two-hour, interactive online workshop, participants will sail together to common ground and co-create a shared understanding of central concepts regarding a provided case. Participants learn and apply the concept of fruitful friction and use the metaphor of sailing. Fruitful friction is a concept that deliberately...conference paper 2021

van Paassen, M.M. (author), Reitsma, J.P. (author), Huijbrechts, Erik-Jan A. M. (author), Borst, C. (author), Landman, H.M. (author), Mulder, Max (author)In the analysis of human performance and human error, considerable attention is given to the cognitive processes of actors involved in error or success scenarios. Even with awareness of hindsight bias, it takes effort to understand the actions of agents in later inspection of error scenarios. One such topic of heated discussion was the perceived...conference paper 2021

de Rooij, G. (author), Borst, C. (author), van Paassen, M.M. (author), Mulder, Max (author)Allocation is a challenge for higher levels of automation in air traffic control, where flights can be dynamically assigned to either a human or an automated agent. Through an exploratory experiment with six professional air traffic controllers, insight was gained into the possibilities and challenges of human-automation teamwork in an en-route...conference paper 2021

Ruan, J. (author), Ghose, R. (author), Mulder, W.A. (author)Induced seismicity from a gas-producing region such as Groningen is believed to be caused by reservoir depletion due to long-term gas production. However, because of the complexity and uncertainty regarding the underground structure and composition, it is difficult to quantify the effect on induced seismicity due to gas production. Here we use...poster 2021

Mulder, W.A. (author)ABSTRACTWhen modeling wave propagation, truncation of the computational domain to a manageable size requires nonreflecting boundaries. To construct such a boundary condition on one side of a rectangular domain for a finite-difference discretization of the acoustic wave equation in the frequency domain, the domain is extended on that one side to...journal article 2021

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

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

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

It relies on an explicit coupling of linearized vehicle and Motion Cueing Algorithm dynamics. Modal analysis subsequently performed on this coupled system reveals the degree of distortion imposed by the Motion...journal article 2021

Hein, C.M. (author), Mulder, I. (author), Sennema, Hilde (author)Over the last decades, values have been re-addressed in planning, policies, businesses, heritage and education. While these fields seem to agree on the importance of values, it is often unclear what actors mean by values, and how they use these values to shape decisions.
