Microscopic Characterization of Modified Phenol-Formaldehyde Resin Penetration of Bamboo Surfaces and its Effect on Some Properties of Two-Ply Bamboo Bonding Interface

BioResources, 2014
The bonding interface between bamboo elements and adhesives is presumed to be significantly influenced by the degree of adhesive penetration into the porous network of interconnected cells of bamboo surfaces.

Combined denoising filter for fringe pattern in electronic speckle shearing pattern interferometry [PDF]

, 2015
We propose an effective image denoising filter that combines an improved spin filter (ISF) and wave atoms thresholding (WA) to remove the noise of fringe patterns in electronic speckle shearing pattern interferometry.
