Manders, A.M.M. (author), Ketzel, M. (author)Air quality in Europe has been considered an issue since the 1950s and has improved considerably over the past decades. Emissions in 2018 were reduced considerably as compared to 2005, with emission reductions of SOx of more than 50%, of NOx of about 40% and of PM10 of about 25%. Nowadays, many areas comply with the limit values of the European...bookPart 2023

(author)Background: The global COVID-19 pandemic has resulted in a greater interest in improving the ventilation of indoor environments in order to remove aerosolized virus and thus reduce transmission. Air purification systems have been proposed as a solution to improve aerosol removal. Aim: The aim was to determine the efficacy of air purification...article 2023

(author)The human mind harbors various mechanisms for coping with stress, but what role does physical behavior play? Inspired by ethological observations of autogrooming activity across species, we offer a general hypothesis: cleaning attenuates effects of stressful events. Preregistered behavioral and psychophysiological experiments (N = 3,066 in...article 2022

van der Weijst, R. (author), van Keulen, T. (author), Willems, F.P.T. (author)Exhaust gas recirculation (EGR) is an often applied mechanism to suppress the emission of NOx in Diesel engines. EGR however, induces a pumping-loss, which reduces the fuel efficiency of the engine. The corresponding control problem is to track a reference EGR fraction, while simultaneously using the available actuators to minimize pumping-loss....conference paper 2019
