On the origin of photons : understanding excitons and multiexcitons in colloidal semiconductor nanocrystals
TL;DR: In this paper, the authors developed tools to directly study triexciton emission in colloidal semiconductor nanocrystals and applied new high-order correlation methods to study the emission statistics and dynamics of the tri-exciton, biexciton, and monoexciton.

Advanced strain and mass transfer analysis in crustal-scale oroclinal buckling and detachment folding analogue models
TL;DR: In this article, the deformation dynamics of oroclinal buckling were analyzed using the PIV (particle image velocimetry) method and several post-processing algorithms on the derived displacement field and calculated the velocity and strain components.

Comparative analysis of particle image velocimetry and acoustic Doppler velocimetry in relation to a pool-type fishway flow
TL;DR: In this paper, particle image velocimetry and acoustic Doppler velo-imaging (ADV) were used in a pool-type fishway with bottom orifices to measure velocity at several locations in planes parallel to the bottom and to the sidewalls.

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.

Determination of displacements using an improved digital correlation method
TL;DR: An improved digital correlation method is presented for obtaining the full-field in-plane deformations of an object by numerically correlating a selected subset from the digitized intensity pattern of the undeformed object.

Fundamentals of digital particle image velocimetry
TL;DR: In this paper, the measurement principle of digital particle image velocimetry (PIV) is described in terms of linear system theory and conditions for PIV correlation analysis as a valid interrogation method are determined.
