second mining
3.Aimed at the advancing jack massive damages phenomenon of ZZ6400 hydraulic support which used on the W1805 working surface in the second Xin Ji mining company? this issue carries on a deeply and systematically analysis and proposes a feasible improvement schemes? obtains a good effect? and provides the rederence for the select of similar support likes ZZ7600、ZZ1000 and so on.
6.There are many advantages to such an arrangement: it will enable us, first, to expand our exports; second, to bring about the technical transformation of the coal-mining industry; and third, to absorb more of the labour force.
7.Taking Second Songhua River as study area, SQL Server-based spatial data warehouse isconstructed, and GIS, statistical data mining, visualized data mining, BP neural network areadopted to pretreat data, design water quality evaluation and forecast model, and analyze forspatial distributing discipline of water quality.
8.The original Snort intrusion detection system was based on single data pack inspection, however, because of network mass information, more and more attack packages use data dividing means to evade the detection of Snort. Herein, the author introduces data mining technology into the key detection part of this system, and presents "second detection module", as well as a detection way based on the data mining technology, so as to provide a sound theory foundation for future research.
9.Intrusion detection,as an active security defending technique,is the second guard for computer network,following network firewall,which is a hot research topic in network security field nowadays.Network intrusion detection system model and realization based on data mining is emphasized in this paper,one model with simple rules and protocol analysis and data mining analysis is proposed,and the realization method of intrusion detection system based on data mining is specially discussed.
10.second, it analyzed the disadvantage of the current study on CBR and proposed applying GA in combination and optimize to resolve them, and advanced a methodology of mining the relationship of cases to search those case being similar in the term of function or action principle for the purpose of original colony of GA, thus conquer the blindness of the produce of the original colony of GA so as to quicken the convergence of the operation of GA.
