Light fastness of printing inks: A review
Journal of Graphic Engineering and Design, 2018 Light fastness, in its broadest sense, is the resistance of colours to fading under the influence of a light source. Light fastness is one of the most important physical, and therefore visual, properties sought in both pigments and in the inks ...

Fast Learning of Fast Transforms, with Guarantees
ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022 Approximating a matrix by a product of few sparse factors whose supports possess the butterfly structure, which is common to many fast transforms, is key to learn fast transforms and speedup algorithms for inverse problems. We introduce a hierarchical approach, that recursively approximates the considered matrix into two factors.

Synthesis and application of 2-aminothiadiazole disperse dyes for nylon fabrics [PDF]
Journal of the Serbian Chemical Society, 2001 Some disperse dyes based on 2-amino-5-mercapto-1,3,4-thiadiazole have been prepared by coupling with various N-arylacrylamides. The dyes were characterized by IR spectral studies and elemental analysis. All the dyes were applied as disperse dyes on nylon
