In this paper, an intelligent power management scheme for embedded systems with wireless applications is proposed to reduce the power consumption of the overall system. The proposed method is based on the feedback of the extreme channel state indicator that is designed to detect the extremely bad channel condition. The considerable power reduction is achieved by turning off modules within the e...

We study the extremal dynamics emerging in an out-of-equilibrium one-dimensional Jepsen gas of $(N+1)$ hard-point particles. The particles undergo binary elastic collisions, but move ballistically in-between collisions. The gas is initally uniformly distributed in a box $[-L,0]$ with the "leader" (or the rightmost particle) at X=0, and a random positive velocity, independently drawn from a dist...

Consider n i.i.d. random vectors on R2, with unknown, common distribution function F . Under a sharpening of the extreme value condition on F , we derive a weighted approximation of the corresponding tail copula process. Then we construct a test to check whether the extreme value condition holds by comparing two estimators of the limiting extreme value distribution, one obtained from the tail c...

Ingestion of batteries by children became more frequent in recent years, due to the increasing accessibility of electronic toys and devices to children. We report a fatal evolution of battery ingestion in a 2-month-old boy.Lithium battery ingestion is a serious condition with high risk of life-threatening complications in childhood and it can be fatal especially in extreme age, under 6 months. ...
