Near-Field Millimeter-Wave Imaging via Multi-Plane MIMO Arrays
IEEE Access, 2023 Multiple-input multiple-output (MIMO) array-based millimeter-wave (MMW) imaging has broad application prospects in concealed weapons detection due to its capability of high resolution at a reasonable cost.

Finite Element Modelling and Simulation of the Hysteretic Behaviour of Single- and Bi-metal Cantilever Beams using a Modified Non-linear Beta-damping Model [PDF]
Journal of Applied and Computational Mechanics, 2021 This paper explores a novel non-linear hysteresis model obtained from the modification of the conventional Kelvin-Voigt model, to produce a non-viscous hysteretic behaviour that is closer to metal damping. Two case studies are carried out for a vibrating

Optomechanical time-domain reflectometry [PDF]
Nature Communications, 2018 AbstractOptical fibres constitute an exceptional sensing platform. However, standard fibres present an inherent sensing challenge: they confine light to an inner core. Consequently, distributed fibre sensors are restricted to the measurement of conditions that prevail within the core. This work presents distributed analysis of media outside unmodified,

Real-time measurement system for determining metal concentrations in water-intensive processes
Open Engineering, 2020 The main purpose of this paper is to demonstrate the potential of time-domain nuclear magnetic resonance (TD-NMR) technology for monitoring the concentrations of metal ions in water-based solutions. The main focus of this work was paramagnetic ions, such

The Validity of Ultra-Short-Term Heart Rate Variability during Cycling Exercise
Sensors, 2023 Ultra-short-term heart rate variability (HRV) has been validated in the resting state, but its validity during exercise is unclear. This study aimed to examine the validity in ultra-short-term HRV during exercise considering the different exercise ...
