A recent pilot study by Smith et al (2025) has broken new ground by combining two powerhouse technologies - the flexiVent and X-ray Velocimetry (XV) - to map the functional decline of the lungs during tumor progression. ...
A multi-view imaging system for tomographic particle imaging velocimetry was used to measure the 3D flow field during a full pulse cycle. ...
In this work, we establish a standard video-processing protocol by analyzing more than 10 Gb of footage data captured during low discharge regime from May 2nd to 11th, 2015, through particle tracking velocimetry (PTV). We show that good image-based velocity data can be obtained throughout the day – from 6 am to 8 pm – despite the challenging experimental settings (direct sunlight ...
Turbidity and acoustic measurement are alternative indirect methods to determine sediment concentration. Acoustic Doppler velocimetry can be used to estimate suspended sediment concentration (SSC) with the signal-to-noise ratio (SNR) in the water. ...
In this laboratory study, an advanced flow visualization technique – particle image velocimetry (PIV) – was employed to investigate the change of shape of activated sludge flocs in water and its influence on the material transport characteristics of the flocs. ...
Turbulent flow inside street canyons was studied using Laser Doppler Velocimetry (LDV) in wind–tunnel experiment. Spatial distribution of momentum flux and moments of third and fourth order of velocity components obtained from one–point measurement are investigated. ...
Physical modelling, under neutral stratification conditions, was used to provide visualisation, pollutant concentration and velocimetry measurements above and inside test canyons amidst surrounding urban roughness. ...
The water mist is generated by a single pressure nozzle and the diffusion flame is produced from PVC samples, respectively. The Laser Doppler Velocimetry/Adaptive Phase Doppler Velocimetry LDV/APV system is employed to determine the water mist characteristics. ...
