There are growing number of people using mobile computing devices such as Smart phones and tablets, to run different types of network applications. The cellular radio interface for communication in those network applications can cause significant energy drains. This is mainly because of the RaidoTails when the cellular radio remains in high energy state after communication has ended. To solve t...

In order to study copula families that have different tail patterns and tail asymmetry than multivariate Gaussian and t copulas, we introduce the concepts of tail order and tail order functions. These provide an integrated way to study both tail dependence and intermediate tail dependence. Some fundamental properties of tail order and tail order functions are obtained. For the multivariate Arch...
