van der Eerden, F. (author), van den Berg, F. (author), van Heijningen, A. (author)Noise contours around military training areas are calculated by using: a) the measured source strength for the impulsive sources and b) the calculated sound propagation using a representative set of meteorological situations. For high-energy impulsive sounds the source strength is measured at distances beyond 100 meters, where peak levels are...conference paper 2022

(author), Bruno, A. (author), Terhal, B.M. (author), Dicarlo, L. (author)Conditional-phase (cz) gates in transmons can be realized by flux pulsing computational states towards resonance with noncomputational ones. We present a 40 ns cz gate based on a bipolar flux pulse suppressing leakage (0.1%) by interference and approaching the speed limit set by exchange coupling. This pulse harnesses a built-in echo to enhance...article 2019

Belfroid, S.P.C. (author), Pereboom, H.P. (author), González Díez, N. (author), Anantharaman, A. (author)Multiphase flow induced vibrations are difficult to calculate. This is in part the prediction of the force frequency spectrum at a single bend, part the influence of bends on the multiphase flow behavior and therefore the prediction of the multiphase flow characteristics between bends. In this paper, the evolution of the forces between...conference paper 2019

Dol, H. (author), Colin, M. (author), van Walree, P. (author), Otnes, R. (author)For remote deployment of unmanned/autonomous underwater vehicles that, for reasons of size, power usage and cost, communicate acoustically in relatively high frequency bands, a backbone underwater acoustic network needs to support multiple frequency bands with the communication streams being able to cross over between bands as required. This...conference paper 2018

Nieuwenhuizen, R.P.J. (author), Bouwman, D.D. (author), Schutte, K. (author)High resolution images are critical for a wide variety of military detection, recognition and identification tasks. Super-resolution reconstruction algorithms aim to enhance the image resolution beyond the capability of the imaging system being used. Until recently, undersampling of the optical signal on the image sensor has been the key factor...conference paper 2018

Lee, J.S. (author), Violato, D. (author), Polifke, W. (author)This study addresses acoustical characteristics, in particular, sound generation of intermittent flow regime in a horizontal pipe through an orifice, based on recorded pressure fluctuations and videos of upstream and downstream flow of the orifice. The flow regimes of interest are plug flow and slug flow, respectively, where sharp-edged and...article 2016

Li, Y. (author), Hoogeboom, P. (author), Russchenberg, H. (author)Fog is a significant factor affecting the public traffic because visibility is reduced to a large extent. Therefore the determination of optical visibility in fog from radar instruments has received much interest. To observe fog with radar, high frequency bands (millimeter waves) have the best option. A 35 GHz cloud radar at the Cabauw...conference paper 2014

(author), TNO Defensie en Veiligheid (author)The goal of the present study was to explore how simulator motion cuing affects the driver's control performance of a car. Steering behavior was used as a measure of control performance. The experimental task was a slalom maneuver in which the velocity of the car was limited to 70 km/h. Subjective and objective variables were measured. The paper...article 2010

(author), TNO Defensie en Veiligheid (author)World-wide a concern exists about the influence of man-made sound on marine life and particularly on marine mammals. One of the acoustic polluters of the world’s oceans is high-power active sonar. An early warning system at the sound source, which is based on passive detection of marine mammals, could avoid exposure of marine mammals to...conference paper 2005
