(author), Vermeulen, R.C.H. (author)Indoor dust has been postulated as an important matrix for residential pesticide exposure. However, there is a lack of information on presence, concentrations and determinants of multiple pesticides in dust in residential homes close to treated fields. Our objective was to characterize the spatial and temporal variance of pesticides in house...article 2022

Sijs, J. (author), van Vught, W. (author), Voogd, J. (author)Autonomous robots that operate in indoor, uncertain environments move around from one location to the next to fulfill a set of ordered task. To do so, they need a floor plan of the building to plan their route. In case the building is unfamiliar to a robot it can employ online mapping techniques, though these techniques are resource intensive...conference paper 2020

Fockens, T.W.H. (author), Zwamborn, A.P.M. (author), Leferink, F. (author)Radio noise of man-made origin has been measured and studied since the 50s of the past century. From that time on, especially in the last two decades, the electromagnetic environment has changed due to the wide spread and increasingly complicated electronic and computing equipment in domestic and work premises. Not only the character of man-made...article 2019

(author)Background: Randomised controlled trials (RCTs) are the gold standard to estimate treatment effects. When patients receive effective treatment over time they may reach the limit of a certain measurement scale. This phenomenon is known as censoring and leads to skewed distributions of the outcome variable with an excess of either low (floor...article 2018

(author)Proximity to facilities emitting polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/F) has been associated with increased risk of non-Hodgkin lymphoma (NHL). There is limited information about whether proximity to industrial sources leads to indoor PCDD/F contamination of homes. We measured carpet dust concentrations (pg/g...article 2017

(author), Wolkoff, P. (author)Cleaning agents often emit terpenes that react rapidly with ozone. These ozone-initiated reactions, which occur in the gas-phase and on surfaces, produce a host of gaseous and particulate oxygenated compounds with possible adverse health effects in the eyes and airways. Within the European Union (EU) project OFFICAIR, common ozone-initiated...article 2014

Tutenel, T. (author), Smelik, R.M. (author), Lopes, R. (author), de Kraker, K.J. (author), Bidarra, R. (author)Computer games often take place in extensive virtual worlds, attractive for roaming and exploring. Unfortunately, current virtual cities can strongly hinder this kind of gameplay, since the buildings they feature typically have replicated interiors, or no interiors at all. Procedural content generation is becoming more established, with many...article 2011

Nauts, P. (author), van Doesburg, W. (author), Krahmer, E. (author), Cremers, A. (author)In this study we investigate miscommunications in interactions between human pilots and a virtual wingman, represented by our virtual agent Ashley. We made an inventory of the type of problems that occur in such interactions using recordings of Ashley in flight briefings with pilots and designed a perception experiment to find evidence of human...conference paper 2011

(author), TNO Bouw en Ondergrond (author)In October 2007, a floor made up of pre-cast prestressed hollow core floor elements suffered early partial collapse during a fire in a carpark of a moderately high new building in Rotterdam, predominantly in use for housing and for limited enterprise. The damage pattern revealed horizontal cracks through the webs of the hollow core slabs,...bookPart 2010

Rijnveld, N. (author), van den Braber, R. (author), Fraanje, P.R. (author), van den Dool, T.C. (author)TNO Science and Industry and MECAL have developed a six degree of freedom vibration isolation system that suppresses both floor vibrations and direct forces on a table top. The achieved reduction of transmissibility and compliance is 40 dB between 1 and 50 Hz in vertical direction, and 30 dB between 1 and 20 Hz in horizontal direction. Key...conference paper 2010

(author)Modern games often feature highly detailed urban environments. However, buildings are typically represented only by their facade, because of the excessive costs it would entail to model all building interiors of a city by hand. Although there exist automated procedural techniques for building interiors, their application is to date limited. One...conference paper 2010

Galanti, F.M.B. (author), Koopman, A. (author), TNO Bouw en Ondergrond (author)Vibration insulation of buildings is often achieved by introducing springs in the foundation. It can be a very effective measure, especially against vibration induced noise, but also a very costly one. There is a need for less costly measures which, although less effective, may achieve the required vibration reduction. For a specific case such...conference paper 2009

TNO Bouw en Ondergrond (author), Waarts, P.H. (author), van Duin, F. (author)The design of slender floor structures, as made in steel or composites, is often limited by the serviceability criteria. Many papers [3-12] describe the calculation of vibrations of floors. However, there is no uniform and simple method available to describe the vibrations and the level of annoyance they cause. In the period 2000-2005 an ECSC...article 2007

Gerretsen, E. (author), Technisch Physische Dienst TNO - TH (author)Some years ago a model was described for the calculation of the weighted airborne sound insulation between dwellings. Further work has been done since in order to increase the applicability of this model, including the extension to octave band calculations. Besides airborne sound, impact sound is also of importance. Therefore the calculation...article 1986
