(author)We investigate the effects of wind–wave interactions on the surface sea-spray-generation flux. To this end, the Marine Aerosol Tunnel Experiment (MATE2019) was conducted at the Pytheas Institute large wave–wind facility in Luminy (Marseille, France) over the period June–July 2019. A unique range of air–sea boundary conditions was generated by...article 2021

Calvert, S.C. (author), Taale, H. (author), Snelder, M. (author), Hoogendoorn, S.P. (author)In probabilistic traffic models, consideration of stochasticity in the dynamics of traffic gives a closer representation of a traffic system in comparison to that of a deterministic approach. Monte Carlo simulation is a broadly accepted method to consider variations in traffic within modelling. In this contribution, the possibility of increasing...article 2014

Janssen, S.A. (author), Salomons, E.M. (author), Vos, H. (author), de Kluizenaar, Y. (author)Environmental noise annoyance due to transportation noise in the home environment has been widely studied, and exposure-response relationships have been established previously for the expected percentage of annoyed residents with the most exposed façade exposure level as a determinant. However, relatively little is known about the evaluation of...conference paper 2013

(author)The authors automated the selection of foods in a computer system that compiles and processes tailored FFQ. For the selection of food items, several methods are available. The aim of the present study was to compare food lists made by MOM2, which identifies food items with highest between-person variance in intake of the nutrients of interest...article 2010

(author), TNO Kwaliteit van Leven (author)In metabolomics research a large number of metabolites are measured that reflect the cellular state under the experimental conditions studied. In many occasions the experiments are performed according to an experimental design to make sure that sufficient variation is induced in the metabolite concentrations. However, as metabolomics is a...article 2009

(author), TNO Defensie en Veiligheid (author)This paper presents a theoretical and empirical analysis of Expected Sarsa, a variation on Sarsa, the classic onpolicy temporal-difference method for model-free reinforcement learning. Expected Sarsa exploits knowledge about stochasticity in the behavior policy to perform updates with lower variance. Doing so allows for higher learning rates and...conference paper 2009

(author), TNO Defensie en Veiligheid (author)The majority of studies investigating interactions between vision and touch have typically explored single events, presenting one object at a time. The present study investigates how tactile-visual interactions affect competition between multiple visual objects in more dynamic cluttered environments. Participants searched for a horizontal or...article 2009

(author), TNO Kwaliteit van Leven (author)Objectives: Workers in many industries are exposed to endotoxins, which may cause adverse health effects. In exposure assessment, information about exposure variability is essential. However, variability in exposure has rarely been investigated for biological agents and more specifically for endotoxin. Therefore, variance components and...article 2008
