Quality of the civil engineering in a city can demonstrate the level of economic development, city image and the ability of governance of this specific area. Utilizing data mining method and algorithm, as well as the quality index of the civil engineering constructed from a large scale consumer survey, the results revealed that, as a whole, the quality of civil engineering in China is not quite good...
IDS (Intrusion Detection system) is an active and driving defense technology. This paper mainly focuses on intrusion detection based on data mining. The aim is to improve the detection rate and decrease the false alarm rate, and the main research method is clustering analysis. The algorithm and model of ID are proposed and corresponding simulation experiments are presented. Firstly, a method to reduce...
Interleaver is the only means for user separation in interleave-division multiple-access (EDMA) systems. A user-specific interleaver design method based on matrix cyclic shifting is proposed, and simulation comparison with random interleaver in AWGN channel is completed. The results show that the matrix cyclic shifting interleaver can maintain almost the same BER performance with random interleaver...
This paper proposes an efficient shape reconstruction method from sectional data in 3-axis Numerical Control (NC) machining. A merge-divide algorithm is proposed to construct triangle meshes for machined surfaces with arbitrary shape and genus. The algorithm is of linear complexity due to the special property of the NC data. The method is used to interference detection and space cutter compensation...
In recent work, we introduced the notion of a construction tree of simplices for a linkage L under distance constraints, and showed that the deformation space DSpace(L) of such an L (i.e., its configuration space CSpace(L) modulo rigid motions of ambient space respecting all system specifications) carries geometrically-defined simplex-based parameters that endow it with a ldquopractically piecewise-convexrdquo...
Some 110 kV arrester base-plate isolator in the 110 kV electric substation dominated by power transformation Dept.1, Foshan power supply bureau, burst frequently in the last years. The most serious one ruptured just working three months. This paper talks about the cause of disruption, the settlement and the effect of crack control.
Internet is overwhelming, personalized content recommendation system offers spam filtering service and suggests useful information to the end users. It is a hotspot in the research area of content management on WWW. Traditional recommendation systems do the data mining on web access logs, discover user's access patterns, and filter the information on behalf of the user at the server side. One critical...
