Grottoli, M. (author), Mulder, Max (author), Happee, R. (author)The use of driving simulators for training and for development of new vehicles is widely spread in the automotive industry. In the last decade, a few motorcycle riding simulators have been developed for similar purposes, with focus on maneuvering at high speed. This article presents the subjective and objective evaluation of a motorcycle...journal article 2022

Marradi, C. (author), Mulder, I. (author)Bottom-up initiatives of active citizens are increasingly demonstrating sustainable practices within local ecosystems. Local urban farming, sustainable agri-food systems, circular supply chains, and community fablabs are exemplary ways of tackling global challenges on a local level. Although promising in accelerating towards future-proof...journal article 2022

(author), Snik, Frans (author), Stam, D.M. (author)Does life exist outside our Solar System A first step towards searching for life outside our Solar System is detecting life on Earth by using remote sensing applications. One powerful and unambiguous biosignature is the circular polarization resulting from the homochirality of biotic molecules and systems. We aim to investigate the...conference paper 2022

Weijers, M.J. (author), Karanth, P. (author), Ganapathy, S. (author), Mulder, F.M. (author)Nanostructured solid composite electrolyte or nano-SCE, which is composed of an ionic liquid, nanoporous silica, and residuals of immobilized precursor components, shows promising synergistic properties. The ionic conductivity of nano-SCE is in the range of 2–5 mS cm<sup>−1</sup>, which exceeds the bulk ionic liquid conductivity at ambient...journal article 2022

Rademacher, Markus (author), Gosling, Jonathan (author), Pontin, Antonio (author), Toroš, Marko (author), Mulder, J.T. (author), Houtepen, A.J. (author), Barker, P. F. (author)We demonstrate the measurement of nanoparticle anisotropy by angularly resolved Rayleigh scattering of single optical levitated particles that are oriented in space via the trapping light in vacuum. This technique is applied to a range of particle geometries from perfect spherical nanodroplets to octahedral nanocrystals. We show that this...journal article 2022

Vogel, Y.B. (author), Stam, M. (author), Mulder, J.T. (author), Houtepen, A.J. (author)We present a strategy to actively engineer long-range charge transport in colloidal quantum dot assemblies by using ligand functionalities that introduce electronic states and provide a path for carrier transfer. This is a shift away from the use of inactive spacers to modulate charge transport through the lowering of the tunneling barrier...journal article 2022

(author)The electrochemical nitrogen reduction reaction (NRR) is a promising alternative to the current greenhouse gas emission intensive process to produce ammonia (NH<sub>3</sub>) from nitrogen (N<sub>2</sub>). However, finding an electrocatalyst that promotes NRR over the competing hydrogen evolution reaction (HER) has proven to be difficult. This...journal article 2022

Mulder, W.A. (author)When solving the wave equation with finite elements, mass lumping allows for explicit time stepping, avoiding the cost of a lower-upper decomposition of the large sparse mass matrix. Mass lumping on the reference element amounts to numerical quadrature. The weights should be positive for stable time stepping and preserve numerical accuracy....journal article 2022

Friesen, D. (author), Borst, C. (author), Pavel, M.D. (author), Masarati, Pierangelo (author), Mulder, Max (author)This paper investigates the effects of different automation design philosophies for a helicopter navigation task. A baseline navigation display is compared with two more advanced systems: an advisory display, which provides a discrete trajectory suggestion; and a constraint-based display, which provides information about the set of possible...journal article 2022

Lopez Reyes, M.E. (author), Mulder, I. (author)Participatory methods have been widely explored in the public sector to democratize city-making projects and foster civic engagement. Although well-intentioned, participatory processes still too often exclude citizens. The current study looks for elements enabling city makers to articulate an inclusive Participatory City Making process. Starting...conference paper 2021

Kolff, Maurice (author), Venrooij, J. (author), Schwienbacher, Markus (author), Pool, D.M. (author), Mulder, Max (author)When designing driving simulation experiments with motion cueing, it is often necessary to make choices between Motion Cueing Algorithms (MCAs) without being fully able to know how well an MCA will perform during the experiment. Choices between MCAs can therefore be greatly supported by previous measurements or predictions of motion cueing...conference paper 2021

Scaramuzzino, Paolo Francesco (author), Pavel, M.D. (author), Pool, D.M. (author), Stroosma, O. (author), Quaranta, Giuseppe (author), Mulder, Max (author)Training has the potential to inject a “safety vaccination” into the rotorcraft community by reducing the number of accidents. The term training should not be intended only in a strict sense, i.e., as pilot technical skills training, but more broadly as risk avoidance and safety culture training. As in the case of vaccination, where immunity is...conference paper 2021

Cupillard, Paul (author), Mulder, W.A. (author), Anquez, Pierre (author), Mazuyer, Antoine (author), Barthélémy, J. (author)The Earth interior contains heterogeneities at all scales, ranging from pores and mineral grains to major global units. On the contrary, seismic recordings only contain variations larger than the minimum wavelength λmin. The heterogeneities smaller than λmin are naturally smoothed by the wavefield, leading to effective media when inverting...conference paper 2021

Mulder, W.A. (author)The representation of a force or of a moment point source in a spectral finite-element code for modelling elastic wave propagation becomes fundamentally different in degenerate cases where the source is located on the boundary of an element. This difference is related to the fact that the finite-element basis functions are continuous across...conference paper 2021

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
