Via the survey based on 400 eleventh grade students from five distinct high schools in Shanghai, we learned about the actual situation of CSCL and its connection with high-school level courses in Shanghai. Through this research, we found that the electronic equipment is not a restricted factor for CSCL in high schools of Shanghai any more. On the other hand, it is shown that the teachers were not...
Finite energy is the key point of restraining the development of WSN because of its characteristics such as size. This paper is based on multi-cluster virtual MIMO system in WSN, cluster head node estimates and fuses the other nodes' transmitted signals. Then use LPA to equalize the cluster node heads signals in WSN virtual MIMO system. Experimental results show that comparing with the others classic...
Corpus annotation is an important but difficult part in corpus linguistic research. In addition to speech tagging, bulk or automatic generation of other types of labels, including the labeling of emantics, syntax, discourse and pragmatics, are difficult to achieve. This paper describes the the application of PowerGREP in corpus processing for foreign language teaching, focusing on the three main functions...
