Vibration Measurements on a Cable-Stayed Cyclist Arch Bridge for Assessment of the Dynamic BehaviourVerdenius, S.A. (author), Bronkhorst, A.J. (author), Geurts, C.P.W. (author)The new cable-stayed arch bridge Tegenbosch (Eindhoven, the Netherlands) needed an assessment of its dynamic behaviour under wind loading due to its slender design. Because of wind-induced vibration issues on a number of bridges in the Netherlands with similar designs, it was decided to examine if vortex excitation, wind-rain induced vibration,...conference paper 2023

Harvey-Collard, P. (author), Dijkema, J. (author), Zheng, G. (author), Sammak, A. (author), Scappucci, G. (author), Vandersypen, L.M.K. (author)We report the coherent coupling of two electron spins at a distance via virtual microwave photons. Each spin is trapped in a silicon double quantum dot at either end of a superconducting resonator, achieving spin-photon couplings up to around gs/2π = 40 MHz. As the two spins are brought into resonance with each other, but detuned from the...article 2022

Bekers, D.J. (author)In this paper we revisit and generalize the Multi-Tone Sinusoidal Frequency Modulation (MTSFM), which has been used in the past decade for various Radar and Sonar applications including optimal transmit waveform design, modelling non-linear frequency modulation, high-duty cycle sensors . In its original form, the MTSFM describes a phase...conference paper 2022

(author), Verweij, M.D. (author)Current ultrasonic clamp-on flow meters consist of a pair of single-element transducers which are carefully positioned before use. This positioning process consists of manually finding the distance between the transducer elements, along the pipe axis, for which maximum SNR is achieved. This distance depends on the sound speed, thickness and...article 2021

Vo-Thanh, N. (author), Schoen, E.D. (author), Goos, P. (author)Row–column designs involve two crossed blocking factors. We propose three combinatorial criteria and a criterion based on D-efficiency to identify optimal row–column arrangements of fractional factorial two-level designs. We search for such arrangements in complete catalogs of 16-run and 24-run orthogonal arrays of strength 2 with two-level...article 2020

de Martin, L. (author), van Rossum, W. (author), Ribeiro, D. (author), Anitori, L. (author)It is well known that noise-like waveforms have the inherent property of suppressing ambiguities due to their nonrepetitive nature, as opposed to the more classical linear frequency modulated (LFM) pulsed waveforms. This aperiodicity also improves the robustness against jammers, making these waveforms harder to detect and classify by an enemy....article 2020
