van Leeuwen, T. D. (author), Cleij, D. (author), Pool, D.M. (author), Mulder, Max (author), Bülthoff, H. H. (author)In motion simulation, motion input scaling is often applied to deal with the limited motion envelopes of motion simulators. In this research, the time-varying effects of scaling the lateral specific force up or down during passive curve driving in a car driving simulation are investigated through a simulator experiment. It is concluded that...journal article 2019

van Leeuwen, P.M. (author)Driving simulators provide researchers with a flexible, controllable, safe, and economical tool for a range of applications. A pivotal aspect in the application of driving simulators is the development of measures aimed at describing the behavior and performance of the driver and providing knowledge about the way drivers are controlling their...doctoral thesis 2019

(author)Hemipterans, mosquitoes, and parasitic wasps probe in a variety of substrates to find hosts for their larvae or food sources. Probes capable of sensing and precise steering enable insects to navigate through solid substrates without visual information and to reach targets that are hidden deep inside the substrate. The probes belong to non...journal article 2019

Negi, Naman Singh (author), van Leeuwen, P.M. (author), Happee, R. (author)This study is an extension of a previous work where differences between race-car drivers and normal drivers has been investigated in a high-speed driving task. The study focused on gaining knowledge about driver differences that can be helpful in designing an adaptive ADAS by introducing the driver into the control loop. The present study...conference paper 2019

Negi, Naman Singh (author), van Leeuwen, P.M. (author), Happee, R. (author)Safety is one of the major areas of concerns today in the field of automotive development. Different safety measures have and are being introduced in order to improve driver/passenger and pedestrian safety. Advanced driver assist systems (ADAS) are therefore becoming increasingly important in their role of reducing driver crash risk. A...conference paper 2019

Langowski, Julian K.A. (author), Dodou, D. (author), Kamperman, Marleen (author), van Leeuwen, Johan L. (author)Tree frogs have the remarkable ability to attach to smooth, rough, dry, and wet surfaces using their versatile toe pads. Tree frog attachment involves the secretion of mucus into the pad-substrate gap, requiring adaptations towards mucus drainage and pad lubrication. Here, we present an overview of tree frog attachment, with focus on (i) the...review 2018

Kadu, Ajinkya (author), van Leeuwen, Tristan (author), Mulder, W.A. (author)Seismic full-waveform inversion tries to estimate subsurface medium parameters from seismic data. Areas with subsurface salt bodies are of particular interest because they often have hydrocarbon reservoirs on their sides or underneath. Accurate reconstruction of their geometry is a challenge for current techniques. This paper presents a...journal article 2017

Kadu, Ajinkya (author), Mulder, W.A. (author), van Leeuwen, Tristan (author)Full-waveform inversion attempts to estimate a high-resolution model of the Earth by inverting all the seismic data. This procedure fails if the Earth model contains high-contrast bodies such as salt and if su ciently low frequencies are absent from the data. Salt bodies are important for hydrocarbon exploration because oil or gas reservoirs are...conference paper 2017

(author)Driving is a safety-critical task that predominantly relies on vision. However, visual information from the environment is sometimes degraded or absent. In other cases, visual information is available, but the driver fails to use it due to distraction or impairment. Providing drivers with real-time auditory feedback about the state of the...journal article 2016
