Use of Probability Distribution Matching in H.26L For Adaptive Configuration of UVLC -A Novel Approach
A method for improving the print quality of ink used in ink-jet printers, particularly thermal ink-jet printers, is provided. For an ink typically comprising about 90 to 98 wt % water and about 10 to 2 wt % diethylene glycol plus about 0.1 to 12 wt % dye, the improvement is achieved by adding an additive consisting essentially of about 1 to 30 wt % ethanol, about 1 to 30 wt % n-propanol, about 1 to 10 wt % iso-propanol, or about 0.002 to 0.05 wt % of 2,5,8,11-tetramethyl-6-dodecyn-5,8-diol.
Bi-directional motion vector coding using Universal VLC
Abstract In this paper an error resilient motion vector coding which employs two-way decodable Universal VLC is presented. With this scheme, a part of a bitstream which cannot be decoded in the forward direction due to errors can be recovered by backward decoding. Based on the observation that motion compensated signals are visually more important than residual signals, motion vectors are better protected so that they can be recovered even in the presence of errors. Besides being bi-directionally decodable, Universal VLC has been designed to allow easy encoding and decoding. It has been shown through simulations that the proposed scheme outperforms the conventional method (i.e, non-bi-directional) in terms of PSNR under various error conditions.
Development of polyamide curable modified epoxy novolac resins with improved adhesion and chemical resistance
Purpose – To prepare modified epoxy resins from resorcinol, cresol and phenol for improved adhesion and chemical resistance. To evaluate the properties of such modified epoxy resins.Design/methodology/approach – Epoxy novolac resins (ENRs) were synthesised by condensing epichlorohydrin with novolacs based on different types of substituted phenols for improving adhesion and chemical resistance. Various compositions were made by incorporating different proportions of polyamide resin. The chemical and adhesive strengths of the conventional epoxy and the modified epoxy resins were characterised.Findings – The modified ENR using substituted phenols showed significant enhancement of chemical and adhesive strengths over the conventional DGEBA resin. The modified ENR had an increased number of glycidyl groups (thus increased functionality) of resin, which was responsible for improved chemical and adhesive strengths over the conventional DGEBA resin.Research limitations/implications – The EPN resins used in the pr...
