Gies, C. (author), Struijk, M. (author), Bekesi, E. (author), Veldkamp, H. (author), van Wees, J.D. (author)We present a new method to incorporate paleo-surface temperature effects in steady state 3D conductive temperature models. The workflow approximates the transient effects and incorporates these into steady state models, using appropriate source and sink terms for radiogenic heat production. This allows for rapid models, which can be easily used...article 2021

Rath, S.S. (author), Hoedemaekers, E.R.G.E. (author), Wilkins, S.S. (author)Lithium ion (Li-ion) batteries in electric vehicle (EV) applications must operate within a narrow temperature range to ensure safety, performance and longevity. Hence, advanced thermal management strategies should have access to internal cell temperatures in a battery pack. In real world application, surface temperatures can be measured, but it...conference paper 2020

de Boer, J.G.G.M. (author), Hofmeyer, H. (author), Maljaars, J. (author), van Herpen, R.A.P. (author)A self-supporting sandwich panel facade system under fire is studied. First, a thermomechanical FE model, which comprises the complete facade system, and incorporates material degradation and geometrical nonlinear behaviour except for the insulation material and connections, is loaded by a fire temperature curve. Eurocode design rules then...article 2019

(author)OBJECTIVE: The discomfort caused by rectal probes and esophageal probes for the estimation of body core temperature has triggered the development of gastrointestinal (GI) capsules that are easily accepted by athletes and workers due to their non-invasive characteristics. We compare two new GI capsule devices with rectal temperature during cycle...article 2018

(author)Most models that predict the infrared signature of an object are based on steady-state equilibrium conditions and do not model the dynamic nature of the real world. To gain more understanding of the dynamic infrared signatures of an object, several outdoor experiments were performed, using a CUBI and a small vessel as an object. Dynamic changes...conference paper 2016

Lee, Y. (author), Lee, J. (author), Kim, S. (author), Park, H.S. (author)We investigated high charge density of states (DOS) in the bandgap of MoS2 nanosheets with variable temperature measurements on ionic liquid-gated MoS2 transistors. The thermally activated charge transport indicates that the electrical current in the two-dimensional MoS 2 nanosheets under high charge density state follows the Meyer-Neldel rule....article 2014

Ye, H. (author), Chen, X. (author), van Zeijl, H. (author), Gielen, A.W.J. (author), Zhang, G. (author)The diode forward voltage method with pulsed currents was widely used for monitoring junction temperature (Tj of light-emitting diodes (LEDs). However, a thermal transient effect (TTE) was observed by the pulsed currents and consequent errors were introduced. Thermoelectric physics was conducted to explain this phenomena and a group of...article 2013

(author), TNO Bouw en Ondergrond (author)Black Carbon (BC) quantification methods are reviewed, including new Rock-Eval 6 data on BC reference materials. BC has been reported to have major impacts on climate, human health and environmental quality. Especially for risk assessment of persistent organic pollutants (POPs) it is important to account for risk reduction caused by BC, as...article 2009

(author), TNO Industrie en Techniek (author)Multiphase flow meters are indispensable tools for achieving optimal operation and control of wells as these meters deliver real-time information about their performance. For example, multiphase flow meters located downhole can improve the production of multilateral and multizone wells by timely allocating the zone where a gas or water cone...conference paper 2008

(author), TNO Industrie en Techniek (author)Real-time monitoring of downhole oil, gas and water flows in wells can significantly improve the production performance of these wells when this flow rate information is used to manipulate inflow control valves. An example of this is the allocation of a gas or water cone to its entrance point in a multilateral well, allowing to close down the...conference paper 2008

(author), TNO Bouw en Ondergrond (author)Lateglacial environments at Hijkermeer, northwest Netherlands, were reconstructed by means of chironomid, diatom and pollen analyses. Diatom assemblages indicate that Hijkermeer was a shallow, oligo- to mesotrophic lake during this period. Pollen assemblages reflect the typical northwest European Lateglacial vegetation development and provide an...article 2007

TNO Defensie en Veiligheid (author), de Jong, A.N. (author), Fritz, P.J. (author)Optical refraction tends to occur frequently in the atmospheric boundary layer. Due to a gradient in the temperature as function of height, rays are bending down towards the earth (super-refraction), or up towards to the sky (sub-refraction). As a consequence, images of targets at long range may be distorted and mirages may occur, while the...conference paper 2007
