Effect of N₂ and CO₂ bubbles on gas volume fraction and flow pattern in a quasi-2D bubble column by shadow imaging

This study reports the effect of N₂ and CO₂ bubbles on dilute to dense gas-liquid two-phase bubbly flow. A shadowgraph imaging technique captured bubble images at a high spatiotemporal resolution. The recordings of bubble images allow us to compute gas fraction distribution. It requires challenging segmentation and gas...

The Proposal of a Novel Pattern Matching Technique for Mirror Anamorphosis

Locality mapping captures the displacement imposed by a mirroring surface in anamorphic art. Establishing this mapping for a physical mirror, however, is a difficult task. Applying pattern matching on the distorted reflection is a promising technique, though existing pattern matching strategies are often ill equipped for this particular task....
