Research ArticleOpen accessEvery word in the titleSynthesis, Characterization and Saponification of Poly (AN)-Starch Composites and Properties of their HydrogelsA. Hashem, M. A. Afifi, E. A. El-Alfy, A. HebeishHydrogels based on saponified products of poly (acrylonitrile, AN)-starch composites were prepared, characterized and their water abosrbency properties examined. The term composite refered to the resultant products of polymerizatin of AN with starch in presence of ceric ammonium nitrate (CAN) as initiator, that is the composite consists of poly(AN)-starch graft copolymer, homopoly(AN) , oxidized starch and unreacted starch. Thus AN … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,577 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCorrelating and Modeling of Extracted Features from PVT Images of Composites using Optical Flow Technique and Weight Elimination Algorithm Optimization [OFT-WEA]Mahmoud Zaki IskandaraniA new approach to the use and implementation of Optical Flow technique is presented. The technique extracts features from presented images as a function of reference image and produces percentage of matching between the reference and tested images. The new approach in using Optical Flow lies in replacing the motion part of the algorithm with differential time related changes in … …Journal of Computer Science, Vol. 13, Issue 9 · 29 Sep 2017 · 7,320 accessesView PDFCite
