Assuming that the loss function is convex in the prediction, we construct a prediction strategy universal for the class of Markov prediction strategies, not necessarily continuous. Allowing randomization, we remove the requirement of convexity.

In this paper, we propose an improved adaptive muting method using a sigmoid function for the packet loss concealment algorithm of ITU-T G.722 Recommendation. The packet loss concealment algorithm performs an adaptive muting to prevent the generation of unnecessary noise during packet loss recovery. While muting is linearly and discontinuously performed according to packet errors, our muting ap...

a field experiment was carried out during 2001 in the experimental fields of sugar beet seed institute in karaj. the objective of this study was to determine the response of some quantitative and qualitative traits of three sugar beet lines subjected to continuous water stress and normal conditions. three sugar beet lines 7219-p.69, bp-karaj and 7112 as tolerant, semi tolerant and sensitive to ...
