(author), Mol, J.M.C. (author)Creating durable, eco-friendly coatings for long-term corrosion protection requires innovative strategies to streamline design and development processes, conserve resources, and decrease maintenance costs. In this pursuit, machine learning emerges as a promising catalyst, despite the challenges presented by the scarcity of high-quality...journal article 2024

Yan, J. (author), Stickel, L.S. (author), van den Hengel, L. (author), Wang, H. (author), Ravi Anusuyadevi, P. (author), Kooijman, A.M. (author), Liu, X. (author), Ibrahim, B. (author), Mol, J.M.C. (author), Taheri, P. (author), Mazzarella, L. (author), Isabella, O. (author), Savenije, T.J. (author)The preferential orientation of the perovskite (PVK) is typically accomplished by manipulation of the mixed cation/halide composition of the solution used for wet processing. However, for PVKs grown by thermal evaporation, this has been rarely addressed. It is unclear how variation in crystal orientation affects the optoelectronic properties of...journal article 2023

(author)Past research suggests that displays on the exterior of the car, known as eHMIs, can be effective in helping pedestrians to make safe crossing decisions. This study examines a new application of eHMIs, namely the provision of directional information in scenarios where the pedestrian is almost hit by a car. In an experiment using a head-mounted...conference paper 2022

Mariani, Elena (author), Kooijman, F.S.C. (author), Shah, P. (author), Stoimenova, N. (author)Interactions of users with AI powered solutions (AIPS) have the potential to affect collective behaviours and amplify unanticipated outcomes. Product developers, organisations, and companies are increasingly being expected to take responsibility for the unanticipated outcomes of their products. In this paper we explore a proactive approach to...journal article 2021

Slingerland, G. (author), Kooijman, Julia (author), Lukosch, Stephan (author), Comes, M. (author), Brazier, F.M. (author)This paper focuses on the particular power of storytelling to foster reflection and connections between people in urban life. In fact, the core principles and mechanisms for public storytelling to achieve this have yet to be made explicit. This gap is addressed by introducing a novel reflective storytelling framework that unveils the underlying...journal article 2021

Epke, Michael R. (author), Kooijman, L. (author), de Winter, J.C.F. (author)Automated vehicles (AVs) are able to detect pedestrians reliably but still have difficulty in predicting pedestrians' intentions from their implicit body language. This study examined the effects of using explicit hand gestures and receptive external human-machine interfaces (eHMIs) in the interaction between pedestrians and AVs. Twenty-six...journal article 2021

(author), Enzinger, Norbert (author), Lewandowska, Małgorzata (author)The present study shows results of friction stir welded (FSW) samples after different plastic deformation routes. The welds were made of coarse-grained and ultrafine-grained commercially pure aluminium. As a plastic deformation method a new hybrid process has been chosen, which resulted in obtaining samples with different characteristics of...journal article 2021

Bazilinskyy, P. (author), Kooijman, L. (author), Dodou, D. (author), de Winter, J.C.F. (author)External human-machine interfaces (eHMIs) may be useful for communicating the intention of an automated vehicle (AV) to a pedestrian, but it is unclear which eHMI design is most effective. In a crowdsourced experiment, we examined the effects of (1) colour (red, green, cyan), (2) position (roof, bumper, windshield), (3) message (WALK, DON'T...journal article 2021

(author), Neubert, D. S. (author), Vos, M. J.C. (author), de Winter, J.C.F. (author)Much psychological research uses pupil diameter measurements to investigate the cognitive and emotional effects of visual stimuli. A potential problem is that accommodating at a nearby point causes the pupil to constrict. This study examined to what extent accommodation is a confounder in pupillometry research. Participants solved...journal article 2021

(author)Future automated vehicles may be equipped with external Human-Machine Interfaces (eHMIs). Currently, little is known about the effect of the perspective of the eHMI message on crossing decisions of pedestrians. We performed an experiment to examine the effects of images depicting eHMI messages of different perspectives (egocentric from the...journal article 2021

de Winter, J.C.F. (author), Petermeijer, S.M. (author), Kooijman, L. (author), Dodou, D. (author)Several papers by Eckhard Hess from the 1960s and 1970s report that the pupils dilate or constrict according to the interest value, arousing content, or mental demands of visual stimuli. However, Hess mostly used small sample sizes and undocumented luminance control. In a first experiment (N = 182) and a second preregistered experiment (N =...journal article 2021

(author), Hultman, Lars (author), Petrov, Ivan (author), Greene, J. E. (author), Greczynski, Grzegorz (author)Refractory transition-metal (TM) diborides have high melting points, excellent hardness, and good chemical stability. However, these properties are not sufficient for applications involving extreme environments that require high mechanical strength as well as oxidation and corrosion resistance. Here, we study the effect of Cr addition on the...journal article 2021

Kooijman, G. (author)Organic flocculants are typically only applied in the sludge line and sometimes in quaternary treatment of conventional sewage treatment plants (STPs) that aim for enhanced nutrient removal. However, with the ongoing societal changes directing towards a higher degree of circularity of resources and a higher degree of wastewater treatment demands...doctoral thesis 2020

(author)Driving simulators are regarded as valuable tools for human factors research on automated driving and traffic safety. However, simulators that enable the study of human-human interactions are rare. In this study, we present an open-source coupled simulator developed in Unity. The simulator supports input from head-mounted displays, motion suits,...conference paper 2020

Kooijman, G. (author), de Kreuk, M.K. (author), Houtman, C. (author), van Lier, J.B. (author)Literature frequently reports that colloids in aqueous matrices sorb a large fraction of pharmaceuticals. Since coagulation/flocculation removes colloids, it is expected that coagulation/flocculation in principle should be useful in concentrating pharmaceuticals in wastewater treatment, which would facilitate the treatment of these refractory...journal article 2020

Kooijman, L. (author), Happee, R. (author), de Winter, J.C.F. (author)In future traffic, automated vehicles may be equipped with external human-machine interfaces (eHMIs) that can communicate with pedestrians. Previous research suggests that, during first encounters, pedestrians regard text-based eHMIs as clearer than light-based eHMIs. However, in much of the previous research, pedestrians were asked to imagine...journal article 2019
