Multi-Exposure PIV Measurements of Velocity Fields in Sprays [PDF]
MATEC Web of Conferences, 2022 This paper presents an approach to the use of the PIV method in the diagnosis of sprays generated by an effervescent atomiser. Due to the different density of the liquid phase depending on the distance from the nozzle, problems arise with the correct ...

Velocity Calibration of Doppler Current Profiler Transducers
Journal of Marine Science and Engineering, 2020 Doppler current profilers are used in oceanography to measure oceanic circulation but also in hydrology to calculate the flow of rivers. They allow the retrieval of water mass profiles in terms of velocity and direction.

Experimental Methodology to Characterize the Noise Paths in a Horizontal-Axis Washing Machine
Acoustics, 2023 In this paper, an experimental methodology to characterize the noise paths in a washing machine with a horizontal axis was developed. The noise paths considered in this research were the noise that escapes through holes, the non-resonant path through the

New 3D velocity model of Estonia from GNSS measurements [PDF]
Estonian Journal of Earth Sciences, 2021 The aim of this study was to create a 3D crustal deformation model for Estonia, based on dense Global Navigation Satellite System (GNSS) data (geodetic points with velocities) and validate the existing models of horizontal and vertical crustal ...

Velocity bias in intrusive gas-liquid flow measurements
Nature Communications, 2021 Estimating velocities in gas liquid flows is of importance in many engineering applications. Hohermuth et al. show that previous bubble velocities obtained from intrusive probes have been underestimated and provide a correction scheme for more accurate ...

A Speed Regression Using Acceleration Data in a Deep Convolutional Neural Network
IEEE Access, 2019 A speed estimation method using the acceleration data measured by a wearable device during exercising on a treadmill is described in this paper. The moving speed is estimated by a regression algorithm that implements a deep convolutional neural network ...

Complementarity of Weak Lensing and Peculiar Velocity Measurements in Testing General Relativity [PDF]
, 2010 We explore the complementarity of weak lensing and galaxy peculiar velocity measurements to better constrain modifications to General Relativity. We find no evidence for deviations from GR on cosmological scales from a combination of peculiar velocity ...
