An important aspect of applications with sensor networks is their network lifetimes. Prolonging the network's lifetime by improving the efficiency of routing algorithm has always been investigated. As for the same purpose, this paper focuses on the design of a remote life alerting system and presents an improved routing algorithm used in this system. For(More)
The research on test equating is very important for computerized adaptive testing, test equity, item banking, and teaching quality assessing. Three new test equating methods are proposed in this paper, which are inspired by the goodness-of-fit test statistics. Monte-Carlo study shows that there are differences among three equating methods. The difference(More)
