Position information is important for spatial information grids. In accurate position of datum may lead to mistake decisions or even disastrous actions. In this paper, we study the problem of localization for spatial information grid in underwater environments. There are many challenges facing the localization in underwater environments, because the unavailability of radio frequency. Besides, there...
In this paper, we proposed and realized a corpus pruning method using decision tree. In the process of clustering, instead of conventional method, we measure the distance of pitch contours by feature vector composed by slope mean. The subjective and objective evaluation results showed that synthetic outputs based on corpus pruned through our method are close to outputs based on no-pruning corpus and...
The characteristics of double-circuit transmission lines protection are expatiated. Main protection principles and protection configuration schemes of real operating double-circuit transmission lines in China are introduced. Based on the summarize of protection schemes and engineering experiences, the analysis of tripping reasons and measures of wrong trip incidents of the double-circuit transmission...
The multi-level storage architecture has been widely adopted in servers and data centers. However, while prefetching has been shown as a crucial technique to exploit the sequentiality in accesses common for such systems and hide the increasing relative cost of disk I/O, existing multi-level storage studies have focused mostly on cache replacement strategies. In this paper, we show that prefetching...
