Conformal Invariant Asymptotic Expansion Approach for Solving （3＋1）-Dimensional JM Equation被引量：1
《Communications in Theoretical Physics》2006年第6期979-984,共6页LI Zhi-Fang RUAN Hang-Yu 
The project supported by the Natural Science Foundation of Zhejiang Province of China under Grant No. Y604036 and State Key Laboratory of 0il/Gas Reservoir Geology and Exploitation ＂PLN0402＂ The authors would like to thank Prof. Sen-Yue Lou for his help and discussion.
The （3＋1）-dimensional Jimbo-Miwa （JM） equation is solved approximately by using the conformal invariant asymptotic expansion approach presented by Ruan. By solving the new （3＋1）-dimensional integrable models, ...

An Optimized Approach for Extracting Approximate Functional Dependencies in XML Documents
《Wuhan University Journal of Natural Sciences》2006年第1期127-132,共6页SHI Lei YANG Xiao-chun YU Ge WANG Bin ZHOU Hua-hui 
Supported by the National Natural Science Foun-dation of China (60173051) , Teaching and Research Award Programfor Outstanding Young Teachers in Higher Education Institution ofthe Ministry of Education,the National Research Foundation for theDoctoral Programof Higher Education of China(20030145029) ,andthe Natural Science Foundationfor Doctoral Career Award of LiaoningProvince(20041016)
In this paper, the definition of approximate XFDs based on value equality is proposed. Two metrics, sup port and strength, are presented for measuring the degree of approximate XFD. A basic algorithm is designed for e...
