Review ArticleOpen accessIn the keywordsAdaptive Video Quality Model for UHD Video Broadcasting Using the Principle of InclusionUrvashi Pal, Horace KingIn this study, an adaptive video quality algorithm is developed for Ultra High Definition (UHD) video broadcasting through Digital Video Broadcasting by Satellite 2nd Generation (DVB-S2), where three conditions are responsible for enhancing or reducing the quality of a video signal received by the DVB-S2 Set-Top-Box (STB). The conditions are: Coverage area, Distance between transmitter and receiver and Separation distance. … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 20 Nov 2017 · 7,899 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNumerical Investigation on Turbulent Forced Convection in Heating Channel Inserted with Discrete V-Shaped BafflesAmnart Boonloi, Withada JedsadaratanachaiThe numerical examinations on flow visualization, heat transfer characteristic and performance improvement in a square duct inserted with discrete V-shaped baffles (DVB) are reported. The DVB is designed to reduce the pressure loss when compared with the V-shaped baffle. The influences of the flow blockage ratios (b/H, BR = 0.05-0.20), V-tip directions (V-Downstream and V-Upstream) are investigated for Reynolds number, … …Journal of Mathematics and Statistics, Vol. 12, Issue 1 · 15 Apr 2016 · 7,116 accessesView PDF Cite
