Measurement of three-dimensional stress field of RP model having a notch by using digital holography

open access: yesEPJ Web of Conferences, 2010
We measure three-dimensional stress field of RP model having a V-notch. RP model (Elastic modulues E = 3317 MPa, 9.3 × 7.7 × 50 mm3 having a V-notch) is made of acrylic transparent resin and tracer particle (averaged diameter: 60μm) are dispersed.

A New Particle Extraction Algorithm for Particle Tracking Velocimetry.

open access: yesJournal of the Visualization Society of Japan, 2000
A new method of particle image detection has been implemented and tested for the use in the particle tracking velocimetry. The method benefits from a new algorithm of extracting individual particle images from a massive concentration of particles recorded in the PIV recordings.

Validation of a Particle Image Velocimetry Algorithm Through Comparative Field and Laboratory Analysis

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...

Investigation of Multidimensional Fractionation in Microchannels Combining a Numerical DEM-LBM Approach with Optical Measurements

open access: yesPowders
The fractionation in microchannels is a promising approach for the delivery of microparticles in narrow property distributions. The underlying mechanisms of the channels are however often not completely understood and are therefore subject to current ...

Fiber Tracking Velocimetry for Two-Point Statistics of Turbulence

open access: yesPhysical Review X, 2021
We propose and validate a novel experimental technique to measure two-point statistics of turbulent flows. It consists of spreading rigid fibers in the flow and tracking their position and orientation in time and is therefore named “fiber tracking ...

Assessing the reproducibility of a bioimage analysis workflow characterising tissue flow in Drosophila

open access: yesJournal of Microscopy, EarlyView.
Abstract Reproducibility challenges in bioimage analysis are common. The proliferation of tools and workflows creates a complex ecosystem that is difficult to reproduce without deliberate, explicit reporting and support. We assess the reproducibility of Gehrels et al.(2023) as a representative bioimage analysis workflow.

Holographic Astigmatic Particle Tracking Velocimetry

open access: yes, 2019
The formation of twin images in digital inline holography (DIH) prevents the placement of the focal plane in the center of a sample volume for DIH-based particle tracking velocimetry (DIH-PTV) with a single camera. As a result, it is challenging to apply DIH-PTV for flow measurements in large-scale laboratory facilities or many field applications where

Development of an Imaging‐Based Method for Analyzing Voided Urine Flow Using Conventional and High‐Speed Video Cameras: A Phantom Study

open access: yesLUTS: Lower Urinary Tract Symptoms, Volume 18, Issue 5, September 2026.
ABSTRACT Aims This study examined whether voided urine form could be an independent parameter to evaluate pathology of the lower urinary tract separately from conventional uroflowmetric measurements. We also evaluated a novel combined methodology of dynamically measuring the velocity and cross‐sectional area (CA) of voided urine.

Flexible Dielectric Acoustic Resonator Patch for Tissue Regeneration

open access: yesAdvanced Materials, Volume 38, Issue 43, 3 August 2026.
A flexible dielectric acoustic resonator patch enables MHz‐range ultrasound generation through resonance amplification without using piezoelectric materials. Conformal integration on a curved substrate allows efficient acoustic delivery to tissue‐mimicking environments.
