Stability estimate for scalar image velocimetry
Journal of Inverse and Ill-posed Problems, 2023 Abstract In this paper, we analyze the stability of the system of partial differential equations modelling scalar image velocimetry. We first revisit a successful numerical technique to reconstruct velocity vectors u

Feature Tracking Velocimetry Applied to Airborne Measurement Data from Murg Creek
E3S Web of Conferences, 2018 A new image feature tracking velocimetry is presented and tested on airborne video data available from a previous study at Murg Creek (Canton Thurgau, Switzerland). Here, the seeded flow scenery had been recorded by an off-the-shelf action camera mounted

Uncertainty quantification in particle image velocimetry
Measurement science and technology, 2019 Particle image velocimetry (PIV) has become the chief experimental technique for velocity field measurements in fluid flows. The technique yields quantitative visualizations of the instantaneous flow patterns, which are typically used to support the ...

Image processing technique for hydraulic application
Труды Института системного программирования РАН, 2018 In this paper, we present techniques Surface Flow Image Velocimetry (SFIV) that is a practical extension of Particle Image Velocimetry method (PIV). In particular, this technique is to evaluate the behavior on the surface flow for complex flow.

Particle image velocimetry (PIV) uncertainty quantification using moment of correlation (MC) plane [PDF]
Measurement science and technology, 2018 We present a new uncertainty estimation method for particle image velocimetry (PIV), that uses the correlation plane as a model for the probability density function (PDF) of displacements and calculates the second order moment of the correlation (MC ...

Advanced Materials, EarlyView.A photoactive tweezers system based on photoactive colloids is developed and systematically investigated in this study. Through experimental and theoretical methods, we demonstrate that the photoredox reaction catalyzed by a dye‐sensitized TiO2 particle generates a strong positive phototaxis, enabling self‐entrapment in the beam center.
