Direct Velocity and Shear-Stress Measurements in Shear-Induced Erosion of a Particle Bed
TL;DR: In this article, full-field fluid-velocity measurements for flow over a bed of 3mm-diameter monodisperse glass beads were obtained using digital particle image velocimetry (DPIV) in an aqueous solution of sodium iodide to match the refractive index of the particles.

Experimental Study on Spatial Variation of Mass Transport Induced by Surface Waves Generated in a Finite-Depth Laboratory Flume
TL;DR: In this paper, the effects of the interaction between two independent waves on wave-induced mass transport were investigated in a wave flume and the experimental data exhibit good agreement with the numerical results with respect to particle trajectories and mass transport.

Real-time moving object detection and removal from 3D pointcloud data for humanoid navigation in dense GPS-denied environments
TL;DR: A real‐time 3D perception filter is presented that is capable of detecting and eliminating moving point clusters from the input pointcloud data collected in an indoor environment and a generic tracking method for handling inconsistent motion of objects typically found in indoor environments is proposed.

Particle Image Velocimetry: A Practical Guide
TL;DR: In this paper, the authors present a practical guide for the planning, performance and understanding of experiments employing the PIV technique, which is primarily intended for engineers, scientists and students, who already have some basic knowledge of fluid mechanics and nonintrusive optical measurement techniques.

Digital Particle Image Velocimetry
Christian Willert,Morteza Gharib +1 more
TL;DR: In this article, the directional ambiguity associated with PIV and LSV is resolved by implementing local spatial cross-correlations between two sequential single-exposed particle images, and the recovered velocity data are used to compute the spatial and temporal vorticity distribution and the circulation of the vortex ring.
