In this paper, we consider the joint decoding of Raptor codes on a binary input additive white Gaussian noise channel. Raptor codes are rateless fountain codes that have the attractive property of being universal on the binary erasure channel: they can approach arbitrarily close the capacity, independently of the channel parameter. It has been recently shown that Raptor codes are not universal ...

In 1966 Gallai asked whether all longest paths in a connected graph intersect in a common vertex. This is not true in general and various counterexamples have been found. However, many well-known classes of graphs have the socalled Gallai property, e.g. trees and outerplanar graphs. Recently, de Rezende et al. proved that 2-trees, which are maximal series-parallel graphs, also have this propert...

We prove a functional central limit theorem for Markov additive arrival processes (MAAPs) where the modulating Markov process has the transition rate matrix scaled up by n (α > 0) and the mean and variance of the arrival process are scaled up by n. It is applied to an infinite-server queue and a fork-join network with a non-exchangeable synchronization constraint, where in both systems both the...

background: there is little information about blood supply of the carpal joint in one- humped camel, while there is extensive data about cow and equine species. in order to perform surgeries and diagnostic techniques in carpal region, information about the elements of the joint such as its arteries is necessary. objectives: this study aims at describing the origins, arrangements, and branches o...
