Observation and model of an ellipsoidally symmetric velocity space distribution in a weakly-coupled dusty plasma
Ross Fisher,Edward Thomas +1 more
TL;DR: In this paper, the authors measured the spatially resolved phase space distribution of a dusty plasma system and found that the standard assumption of a spherically symmetric velocity space is not applicable to the observed system.

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.
