Landman, H.M. (author), van Middelaar, Sophie H. (author), Groen, Eric L. (author), van Paassen, M.M. (author), Bronkhorst, Adelbert W. (author), Mulder, Max (author)Background: Mnemonic-type startle and surprise procedures were previously proposed to help pilots cope with startle and surprise in-flight, but effects on performance after procedure execution have not yet been investigated. Objective: Thus, we tested the effectiveness a new mnemonic-type procedure in a moving-base simulator with a non-linear...journal article 2020

(author), Mulder, Max (author)Objective: We tested whether a procedure in a hexapod simulator can cause incorrect assumptions of the bank angle (i.e., the “leans”) in airline pilots as well as incorrect interpretations of the attitude indicator (AI). Background: The effect of the leans on interpretation errors has previously been demonstrated in nonpilots. In-flight,...journal article 2020

Steijlen, A.S.M. (author), Bastemeijer, J. (author), Groen, Pim (author), Jansen, K.M.B. (author), French, P.J. (author), Bossche, A. (author)This paper presents a method to continuously collect and reliably measure sweat analyte concentrations during exercise. The method can be used to validate newly developed sweat sensors and to obtain insight into intraindividual variations of sweat analytes in athletes. First, a novel design of a sweat collection system is created. The sweat...journal article 2020

(author), Dankelman, J. (author)To comply with the large global need for surgery, surgical equipment that fits the challenging environment in low-and middle-income countries (LMICs) should be designed. The aim of this study is to present a context-specific design of an electrosurgical unit (ESU) and a monopolar handheld to improve global access to surgery. This paper...journal article 2020

Heijboer, S.E.H. (author), Tempelman, E. (author), Schumann, Josef (author), Groen, W.A. (author)Current transformational developments in automotive user interface (UI) technology are causing a shift in emphasis from safety and efficiency to emotion and flexibility. The many factors to consider in parallel make this a difficult process, in which technological affordances all too easily push the user to the background. To address this...conference paper 2019

Groen, Olivier (author)A combination of the growth of the offshore wind energy sector and the decline in both species richness and species abundance in the North Sea has inspired the goal to use the scour protection in wind farms as a means to enhance marine life. Present research has focused on general changes which are to be applied to benefit marine life. However,...master thesis 2019

Groen, Maarten (author)It is expected by the EWEA that in the North Sea only the wind energy capacity will increase to 45 GW. In 2015 the capacity was only 5.2 GW. Offshore contractors should be capable of installing lots of turbines and just that is a problem. As turbines increase in size installation vessels need significant upgrades. Therefore, most contractors...master thesis 2019

(author)Aviation safety organizations have recommended that airline pilots are trained for startle and surprise. However, little information is available on useful training interventions. Therefore, a training intervention trial was executed during airline recurrent simulator training. The method consisted of a slow visual scan from the side-window,...conference paper 2019

(author), Mulder, Max (author)Several checklist-based methods have been proposed to help pilots manage startle in unexpected situations. 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

(author)Background & Objective: The need for surgery is currently not met in Sub-Saharan Africa, requiring both extra workforce and surgical equipment. Currently, there is a gap in the availability of surgical equipment which, among others, limits the provision of safe surgery. To design strategies to increase availability, the use of surgical...journal article 2019

Zhao, Dong (author), Lenz, Thomas (author), Gelinck, Gerwin H. (author), Groen, W.A. (author), Damjanovic, Dragan (author), de Leeuw, D.M. (author), Katsouras, Ilias (author)Depolarization in ferroelectric materials has been studied since the 1970s, albeit quasi-statically. The dynamics are described by the empirical Merz law, which gives the polarization switching time as a function of electric field, normalized to the so-called activation field. The Merz law has been used for decades; its origin as domain-wall...journal article 2019

Landman, H.M. (author), Davies, Simon (author), Groen, Eric L. (author), van Paassen, M.M. (author), Lawson, Nicholas (author), Bronkhorst, Adelbert W. (author), Mulder, Max (author)We hypothesized that an incorrect expectation due to spatial disorientation may induce roll reversal errors. To test this, an in-flight experiment was performed, in which forty non-pilots rolled wings level after receiving motion cues. A No-leans condition (subthreshold motion to a bank angle) was included, as well as a Leans-opposite condition ...journal article 2019
