van Gent, P. (author), Farah, H. (author), van Nes, Nicole (author), van Arem, B. (author)Heart rate data are often collected in human factors studies, including those into vehicle automation. Advances in open hardware platforms and off-the-shelf photoplethysmogram (PPG) sensors allow the non-intrusive collection of heart rate data at very low cost. However, the signal is not trivial to analyse, since the morphology of PPG waveforms...journal article 2019

Gudi, A.A. (author), Bittner, M. (author), Lochmans, Roelof (author), van Gemert, J.C. (author)Remote photo-plethysmography (rPPG) uses a remotely placed camera to estimating a person's heart rate (HR). Similar to how heart rate can provide useful information about a person's vital signs, insights about the underlying physio/psychological conditions can be obtained from heart rate variability (HRV). HRV is a measure of the fine...conference paper 2019

Kuipers, J. (author), Wieringa, P.A. (author)The risk of being involved in an accident in the first year after licensing is greater for novice drivers who passed their driving exam the first time than for novice drivers who failed their first driving exam. Enhanced training programmes can shorten the duration of training and can raise the passing rate on the first exam, but can also...conference paper 2018

Neerincx, M.A. (author), Koldijk, Saskia (author), Kraaij, Wessel (author)Employees often report the experience of stress at work. In the SWELL project we investigate how new context aware pervasive systems can support knowledge workers to diminish stress. The focus of this paper is on developing automatic classifiers to infer working conditions and stress related mental states from a multimodal set of sensor data ...journal article 2018

Gedik, E. (author), Cabrera Quiros, L.C. (author), Martella, Claudio (author), Englebienne, Gwenn (author), Hung, H.S. (author)We present an approach to interpret the response of audiences to live performances by processing mobile sensor data. We apply our method on three different datasets obtained from three live performances, where each audience member wore a single tri-axial accelerometer and proximity sensor embedded inside a smart sensor pack. Using these...journal article 2018

(author), Gombert, Andreas K. (author)Knowledge on the genetic factors important for the efficient expression of plant transporters in yeast is still very limited. Phaseolus vulgaris sucrose facilitator 1 (PvSuf1), a presumable uniporter, was an essential component in a previously published strategy aimed at increasing ATP yield in Saccharomyces cerevisiae. However, attempts to...journal article 2018

(author)Anaerobic industrial fermentation processes do not require aeration and intensive mixing and the accompanying cost savings are beneficial for production of chemicals and fuels. However, the free-energy conservation of fermentative pathways is often insufficient for the production and export of the desired compounds and/or for cellular growth...journal article 2018

Finnsson, Eysteinn (author)Sleep is an immensely important biological function and dysregulated sleep can have severe detrimental effects on health and well-being. Over 80 sleep disorders have been classified and of those sleep apnoea is one of the most common, having a prevalence of at least 20 percent in the general population. Sleep apnoea belongs to a family of...master thesis 2017

(author)Trees play a crucial role in the water, carbon and nitrogen cycle on local, regional and global scales. Understanding the exchange of momentum, heat, water, and CO 2 between trees and the atmosphere is important to assess the impact of drought, deforestation and climate change. Unfortunately, ground measurements of tree properties such as mass...journal article 2017

Janssen, N.M. (author)Automated driving is becoming increasingly popular and is often proposed as a solution to commonly known human errors in driving. However, fully autonomous driving has not yet reached the point where it can be implemented in real world driving. Current automated driving systems are often designed in such a way that the role of the human operator...master thesis 2016

Qu, C. (author), Ling, Y. (author), Heynderickx, I. (author), Brinkman, W.P. (author)Bystanders in a real world's social setting have the ability to influence people’s beliefs and behavior. This study examines whether this effect can be recreated in a virtual environment, by exposing people to virtual bystanders in a classroom setting. Participants (n = 26) first witnessed virtual students answering questions from an English...journal article 2015

Dobbe, L.R.M. (author)The aim of this study was to determine if and how specific characteristics of visual information influence the motor control strategy adopted during a visuomotor tracking task. To this end, twenty healthy subjects and two stroke patients were measured. Changes in wrist joint admittance (i.e., wrist rotations due to external forces) due to...master thesis 2014

Martins, A.M.P. (author)The activated sludge process is the preferred technology for biological wastewater treatment. Despite decades of progress and operation serious operating problems still occur with this process. One major problem is the regular occurrence of excessive growth of filamentous bacteria, phenomena known as filamentous bulking sludge. Poor solid-liquid...doctoral thesis 2004
