Stable Feature Flow Fields [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2011 Feature Flow Fields are a well-accepted approach for extracting and tracking features. In particular, they are often used to track critical points in time-dependent vector fields and to extract and track vortex core lines. The general idea is to extract the feature or its temporal evolution using a stream line integration in a derived vector field-the ...

The Flow of the Berry Curvature Vector Field [PDF]
Scientific Reports, 2021 Abstract The concept of Berry phase and Berry curvature has become ubiquitous in solid state physics as it relates to variety of phenomena, such as topological insulators, polarization, and various Hall effects. It is well known that large Berry curvatures arise from close proximity of hybridiz-ing bands, however, the vectorial nature of the ...

Field and flow-based separations [PDF]
Analytical and Bioanalytical Chemistry, 2015 Field-flow fractionation (FFF) and related methods are a set of analytical methods for the separation and characterization of nanoand micro-size analytes. These methods were originally used for the characterization of synthetic polymers and biological macromolecules, before also providing important contributions to the field of environmental sciences ...

Mixing Phenomenon and Flow Field in Ladle of RH Process
Metals, 2019 Particle image velocimetry (PIV) system was adopted to investigate the relationship between the mixing phenomenon and the flow field of a 210 t RH degasser by a 1:4 scale water model. The results of mixing simulation experiments indicated that the mixing
