Abstract A doubly stochastic, conditionally binomial model is proposed to describe volumes of vehicular origin-destination flows in regular vehicular traffic, such as morning rush hours. The statistical properties of this model are motivated by the d

Abstract We analyze the performance of regular decomposition, a method for compression of large and dense graphs. This method is inspired by Szemerédi’s regularity lemma (SRL), a generic structural result of large and dense graphs. In our method,

We study joint restorability of interdependent telecommunications (optical + mobile) and electricity distribution networks after a long-Term blackout. Restorability of a node in either network requires an availability of services of both networks. Si

Peer-to-peer protocols that rely on fully random peer and chunk selection have recently been shown to suffer from instability. The culprit is referred to as the missing piece syndrome, whereby a single chunk is driven to near extinction, leading to a
