Analytical/experimental comparison of the axial velocity in trailing vortices [PDF]
, 2011 The axial velocity of a vortex is a parameter which is known to be strongly related to the vortex breakdown, yet to date a complete description of its physical origins has not been achieved.

Objective speckle displacement resulting from the deformation of shaped objects [PDF]
, 2015 This paper describes an extended theory of the displacement of the objective speckle pattern resulting from displacement and/or deformation of a coherently illuminated diffuse object where the influence of the surface shape is included via the linear ...

Imaging single-cell blood flow in the smallest to largest vessels in the living retina
eLife, 2019 Tissue light scatter limits the visualization of the microvascular network deep inside the living mammal. The transparency of the mammalian eye provides a noninvasive view of the microvessels of the retina, a part of the central nervous system.

EVALUATION OF AIRBORNE IMAGE VELOCIMETRY APPROACHES USING LOW-COST UAVS IN RIVERINE ENVIRONMENTS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Traditional flow velocity measurements in natural environments require contact with the fluid and are usually costly, time-consuming and, sometimes, even dangerous.

Considerations When Applying Large-Scale PIV and PTV for Determining River Flow Velocity
Frontiers in Water, 2021 Large-scale image velocimetry is a novel approach for non-contact remote sensing of flow in rivers. Research within this topic has largely focussed on developing specific aspects of the image velocimetry work-flow, or alternatively, testing specific ...

MRI investigation of granular interface rheology using a new cylinder shear apparatus [PDF]
, 2009 The rheology of granular materials near an interface is investigated through proton magnetic resonance imaging. A new cylinder shear apparatus has been inserted in the MRI device, which allows the control of the radial confining pressure exerted by the ...

Clog-Free Trilobite Filtration: Tunable Flow Setup and Velocity Measurements
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
