Edge-based directional fuzzy filter for compression artifact reduction in JPEG images
We propose a novel method to reduce both blocking and ringing artifacts in compressed images and videos. Based on the directional characteristics of ringing artifacts along edges,...

Numerically stable fluid-structure interactions between compressible flow and solid structures
We propose a novel method to implicitly two-way couple Eulerian compressible flow to volumetric Lagrangian solids. The method works for both deformable and rigid solids and for a...

Recording and using provenance in a protein compressibility experiment
Very large scale computations are now becoming routinely used as a methodology to undertake scientific research. In this context, ‘provenance systems’ are regarded as the equ...
