An improved coordinated charging method was proposed to deal with numerous electric vehicles' (EVs') uncertainty charging habits in this work, this method is an optimization model taking EVs' charging start time and charging power as the control variables. In the model users' charging habit was represented by Binomial distribution and the EVs' uncertainty charging demand was imitated by the Mento...
In communication networks, multiple disjoint communication paths are desirable for many applications. Such paths, however, may not exist in a network. In such a situation, paths with minimum link and/or node sharing may be considered. This paper addresses the following two related fundamental questions. First, in case of no solution of disjoint multiple paths for a given application instance, what...
In data streams or Web scenario at highly variable and unpredictable rates, most fast join algorithms to date rely upon shifting to external join stage as soon as possible when blocked in order to enhance efficiency. But they have trouble with the following issues: the limit of external join and practical executing time. Classical progressive two-way joining technique based on hash, however, fail...
