Pseudo-real Image Sequence Generator for Optical Flow Computations

The availability of ground-truth flow field is crucial for quantitative evaluation of any optical flow computation method. The fidelity of test data is also important when artificially generated. Therefore, we generated sequences of artificial flow fields together with an artificial images based on given real-world sample image. The presented framework benefits of a two-layered approach in whic...

ALOHA: Automatic libraries of helicity amplitudes for Feynman diagram computations

We present an application that automatically writes the Helas library corresponding to the Feynman rules of any Lagrangian, renormalizable or not, in quantum field theory. The code, written in Python, takes the Universal FeynRules Output (Ufo) as an input and produces the complete set of routines (wavefunctions and amplitudes) that are needed for the computation of Feynman diagrams at leading a...

NOTES AND CORRESPONDENCE Distribution of Helicity, CAPE, and Shear in Tropical Cyclones

The previous study of helicity, CAPE, and shear in Hurricane Bonnie (1998) was extended to all eight tropical cyclones sampled by NASA during the Convection and Moisture Experiments (CAMEX). Storms were categorized as having large or small ambient vertical wind shear, with 10 m s as the dividing line. In strongly sheared storms, the downshear mean helicity exceeded the upshear mean by a factor ...

Multiphase flow and tromp curve simulation of dense medium cyclones using Computational Fluid Dynamics

Dense Medium Cyclone is a high capacity device that is widely used in coal preparation. It is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in DMCs complex. In this article the flow pattern simulation of DMC is performed with computational fluid dynamics and Fluent...
