At present, the power system is building up on top of a series of auxiliary systems for examples communication systems, monitoring systems, marketing systems and so on. All the systems work based on the shared power system data which are defined using Common Information Model (CIM). Due to diversiform reasons, errors may exist in the data. Therefore the verification technologies are developed. So...

Recently MapReduce programming model is becoming popular for large scale data intensive distributed applications due to its efficiency, simplicity and ease of use. The Hadoop implementation of MapReduce is one of the most popular tools for many programmers due its ability to hide details of parallel programming from the users. However work on simulating the Hadoop environment is still in its infancy...
Peer-to-peer (P2P) networks are achieved more and more attention, compared with C/S service mode, P2P is more suitable for distributed data flow processing. This paper concentrates on how to answer continuous rank join query in P2P networks. In the algorithm proposed, the data that cannot contribute the final ranked results will be discarded directly based on pre-computing the minimum values of rank...
