Vesela, S. (author), Kingma, B.R.M. (author), Frijns, A.J.H. (author), van Marken Lichtenbelt, W.D. (author)The quality of local skin temperature prediction by thermophysiological models depends on the local skin blood flow (SBF) control functions. These equations were derived for low activity levels (0.8-1 met ) and mostly in sitting or supine position. This study validates and discusses the prediction of foot SBF during activities of 1-3 met in male...article 2019

de Boer, M.H.T. (author), Bouma, H. (author), Kruithof, M.C. (author), Joosten, B. (author)Annotating a large set of images, especially with bounding boxes, is a tedious task. In this paper, we propose an intuitive image annotation tool. This tool not only allows (non-expert) users to annotate images with novel concepts, but is also able to achieve acceptable performance with a smaller number of annotated images. The tool can also...conference paper 2019

Madadi, B. (author), van Nes, R. (author), Snelder, M. (author), van Arem, B. (author)This paper presents a bi-level model to optimize automated-vehicle-friendly subnetworks in urban road networks and an efficient algorithm to solve the model, which is relevant for the transition period with vehicles of different automation levels. We formulate the problem as a network design problem, define solution requirements, present an...article 2019

Malone, K.M. (author), Ognissanto, F. (author), Nitsche, P. (author), Soekroella, A. (author), Hopkin, J. (author)Cooperative systems which rely on vehicle-to-infrastructure communications are designed to tackle important road transport issues, such as safety and pollution. Since the associated monetary commitment is substantial, a clear understanding of the appropriate business models and likely costs, impacts and benefits is necessary before investment...conference paper 2018

Gezici-Koç, Ö. (author), Erich, S.J.F. (author), Huinink, H.P. (author), van der Ven, L.G.J. (author), Adan, O.C.G. (author)An important reason to apply coatings on wood is to protect wood against moisture. As a result of regulations and ecological concerns, there has been a shift towards waterborne coatings, which make coatings intrinsically more sensitive to water. As a consequence of the higher sensitivity to water, the durability of both wood and coatings can be...article 2018

(author)A WiFi (IEEE 802.11g) and BLE combo transmitter (TX) for IoT applications is presented. A wideband digital polar architecture consisting of an all-digital PLL-based frequency modulator and a switched-capacitor digitally-controlled PA achieves optimal energy efficiency for both WiFi and BLE. The dynamic FM correction and AM alias suppression...conference paper 2018

However, current systems have limited perceptual capabilities in the sense that they are not very well adaptable to unknown environments. Human operators, on the other hand, are experts...conference paper 2018

(author)Due to the increasing need for effective security measures and the integration of cameras in commercial products, a huge amount of visual data is created today. Law enforcement agencies (LEAs) are inspecting images and videos to find radicalization, propaganda for terrorist organizations and illegal products on darknet markets.

(author)Source localization using microphone arrays has now become common practice for many applications. Their application for long term monitoring of industrial noise nevertheless remains uncommon. Hence, in 2016 we deployed four microphone arrays near a large industrial area for a period of 12 months and explored the challenges involved. The...conference paper 2017

Copppejans, O.J. (author), Walters, C.L. (author)The local approach to modelling ductile tearing is a useful technique to give insight into fracture mechanics. However, applications of the local approach have been stymied by the high cost of finding the parameters that characterize it because of the number of specimens and expensive post-processing that the testing requires. In this paper, a...conference paper 2017

Saldana, J. (author), Ruiz-Mas, J. (author), Almodovar, C.J.L. (author)Frame aggregation is widely used in 802.11 WLANs in order to provide a significant throughput improvement. However, the latency increase that comes as a counterpart can reduce the quality experienced by the users of applications with real-time constraints. This letter explores the throughput versus latency tradeoff in the context of central...article 2017
