Azevedo Vasconcelos, A.C. (author), Valiya Valappil, S. (author), Schott, D.L. (author), Jovanova, J. (author), Aragon, A.M. (author)Underwater noise resulting from the monopile driving process can cause severe damage to marine wildlife, such as hearing injury, behavioral disturbance, or even death. Although current noise-attenuation techniques used in this process have shown a significant noise reduction at high frequency ranges, mitigating low-frequency noise is still...journal article 2024

Zhang, Junhao (author), Muijzer, Frodo (author), Vallery, H. (author), Veltink, Peter H. (author)Angular momentum, kinetics, and energetics, including total mechanical energy and its rate of change in relation to power exchange, are important quantities when analyzing human motion in sports, physical labor, and rehabilitation. Inertial measurement units (IMU)-based motion capture (MOCAP) systems provide a portable solution for the...journal article 2024

van Dijk, M.P. (author), Hoozemans, Marco J.M. (author), Berger, M.A.M. (author), Veeger, H.E.J. (author)In wheelchair sports, there is an increasing need to monitor mechanical power in the field. When rolling resistance is known, inertial measurement units (IMUs) can be used to determine mechanical power. However, upper body (i.e., trunk) motion affects the mass distribution between the small front and large rear wheels, thus affecting rolling...journal article 2024

van Gils, R.H.J. (author), Kornelisse, R. F. (author), Dankelman, J. (author), Helder, O. K. (author)Background: Compliance with the recommended 30 s drying time of alcohol-based hand rub (ABHR) is often suboptimal. To increase hand hygiene compliance at a neonatal intensive care unit (NICU), we installed an Incubator Traffic Light (ITL) system which shows ‘green light’ to open incubator doors after the recommended drying time. Aim: To...journal article 2024

Hille, Sander C. (author), Theewis, E.S. (author)On spaces of finite signed Borel measures on a metric space one has introduced the Fortet-Mourier and Dudley norms, by embedding the measures into the dual space of the Banach space of bounded Lipschitz functions, equipped with different – but equivalent – norms: the FM-norm and the BL-norm, respectively. The norm of such a measure is then...journal article 2024

van Dijk, M.P. (author), Hoozemans, Marco J.M. (author), Berger, M.A.M. (author), Veeger, H.E.J. (author)An important performance determinant in wheelchair sports is the power exchanged between the athlete-wheelchair combination and the environment, in short, mechanical power. Inertial measurement units (IMUs) might be used to estimate the exchanged mechanical power during wheelchair sports practice. However, to validly apply IMUs for mechanical...journal article 2024

(author)This article introduces a low-jitter low-spur fractional-N phase-locked loop (PLL) adopting a new concept of a time-mode arithmetic unit (TAU) for phase error extraction. The TAU is a time-signal processor that calculates the weighted sum of input time offsets. It processes two inputs - the period of a digitally controlled oscillator (DCO)...journal article 2023

(author), Spriet, Isabel (author), Endeman, Henrik (author), Haringman, Jasper J. (author)In the intensive care unit (ICU), infection-related mortality is high. Although adequate antibiotic treatment is essential in infections, beta-lactam target non-attainment occurs in up to 45% of ICU patients, which is associated with a lower likelihood of clinical success. To optimize antibiotic treatment, we aimed to develop beta-lactam target...journal article 2023

(author), Bakker, Pieter (author), van der Lem, Cock (author)Single layer randomly placed armour units are used in many rubble mound breakwaters around the world. For these armour layers first extraction of units starts at high loads and can then progress quickly. Before the first extraction of a unit, typically no quantitative description of damage can be given. But additional to extraction, breakage of...journal article 2023
