Verification of flow velocity measurements using micrometer-order thermometers [PDF]
Scientific Reports, 2021 In flow velocity measurements, resolution, miniaturization, and accuracy of measuring devices are important issues because the measuring devices significantly affect the flow in the micro-space, sonic flow, and turbulent flow.

Detonation Velocity Measurements Using Rare-Earth Doped Fibres [PDF]
Sensors, 2019 In this paper, a simple detonation velocity measurement scheme is presented, which exploits the length-dependent amplified spontaneous emission (ASE) power emitted by off-the-shelf Er-doped fibres.

Clog-Free Trilobite Filtration: Tunable Flow Setup and Velocity Measurements [PDF]
Micromachines, 2020 The ability to separate and filter out microscopic objects lies at the core of many biomedical applications. However, a persistent problem is clogging, as biomaterials stick to the internal chip surface and limit device efficiency and liability. Here, we

Frequency-comb-calibrated Laser Heterodyne Radiometry for Precision Radial Velocity Measurements [PDF]
The Astrophysical Journal Supplement SeriesDisk-integrated observations of the Sun provide a unique vantage point to explore stellar activity and its effect on measured radial velocities. Here we report a new approach for disk-integrated solar spectroscopy and evaluate its capabilities for solar ...

Optimised Chirped Fibre Bragg Gratings for Detonation Velocity Measurements [PDF]
Sensors, 2019 Over the last decade, the use of chirped fibre Bragg gratings (CFBGs) in detonation velocity experiments has been steadily increasing. In this paper, we show how CFBG design parameters—chirp-rate, reflectivity and apodisation—affect linearity

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

Globally stable velocity estimation using normalized velocity measurement [PDF]
The International Journal of Robotics Research, 2019 The problem of estimating velocity from a monocular camera and calibrated inertial measurement unit (IMU) measurements is revisited. For the presented setup, it is assumed that normalized velocity measurements are available from the camera. By applying results from nonlinear observer theory, we present velocity estimators with proven global stability ...
