Some results relating to the road-coloring conjecture of Alder, Goodwyn, and Weiss, which give rise to an O(n2) algorithm to determine whether or not a given edge-coloring of a graph is a road-coloring, are noted. Probabilistic analysis is then used to show that, if the outdegree of every edge in an n-vertex digraph is δ = ω(logn), a road-coloring for the graph exists. An equivalent re-statemen...

background and aim: traffic accident is one of the main causes of mortality in iran. the damage and injury caused by these accidents threatens human societies severely. rural accidents are often more severe and show harsher consequences because the operational speed is higher on rural roads and highways. world statistics presented by world health organization (who) reveal that about 25 percent ...

Recent electronic devices are connected with each other by various connectivity techniques. This trend makes computing resources distributed over many devices. However, since the general DRM models assume contents and the corresponding rights should be stored in the same space or storage, they cannot fully support distributed environments. To fully utilize the distributed resource and to provid...
