We combine the web usage mining and fuzzy clustering and give the concept of web fuzzy clustering, and then put forward the web fuzzy clustering processing model which is discussed in detail. Web fuzzy clustering can be used in the web users clustering and web pages clustering. In the end, a case study is given and the result has proved the feasibility of using web fuzzy clustering in web pages clustering.

Reaction of SmI2(THF)x with 2 equivalents of NaOAr (Ar = C6H2-tert-Bu3-2,4,6) in THF affords a divalent complex of Sm(OAr)2(THF)3?THF 1 in 90.8% yield. Treatment of 1 with 1,2-dimethoxyethane (DME) leads to the ligand-exchange reaction, and a DME-solvated complex of Sm(OAr)2(DME)2 2 was obtained. Complex 1 crystallizes in monoclinic, space group P21/c with a = 10.366(5), b = 33.024(15), c = 16.123(7) ?, β = 93.197(8)°, V = 5511(4) ?3, Z = 4, C52H90O6Sm, Mr = 961.59, Dc = 1.159 g/cm3, F(000) = 2048, μ(MoKα) = 1.107 mm-1, R = 0.0844 and wR = 0.1401 for 4694 observed reflections. Complex 2 crystallizes in monoclinic, space group C2/c with a = 27.222(5), b = 10.6140(19), c = 17.398(4) ?, β = 110.245(3)°, V = 4716.4(16) ?3, Z = 4, C44H78O6Sm, Mr = 853.41, Dc = 1.202 g/cm3, F(000) = 1808, μ(MoKα) = 1.285 mm-1, R = 0.0361 and wR = 0.0830 for 5210 observed reflections.

针对位姿测量系统会增加被测物重量的问题,设计了网格结构光的视觉位姿测量系统。提出了一种基于二维平面靶标的网格结构光标定算法,利用靶标和结构光的共面性,同时标定网格结构光和相机,实现被测物表面三维点云的获取。为了验证网格结构光点云测量精度,进行了结构光标定实验以及点云精度验证实验,结果表明点云精度在0.04 mm以上。研究了点云配准的位姿测量算法。采用采样一致性初始配准(SAC-IA)算法对测量点云与参考点云进行粗配准,为后续点云精配准提供较好的初始位置。采用改进的迭代闭合点(ICP)算法进行点云精配准,引入随机采样一致(RANSAC)算法和法向量阈值过滤匹配点,以点到面的距离为误差函数,实现位姿测量。进行了点云配准算法对比实验和位姿测量实验,实验结果证明:被测物发生旋转运动时,该系统的最大误差不超过0.25°;平移运动时,最大误差不超过0.35 mm。

Objective:This study evaluated the prognostic power of serum uric acid(UA)in predicting adverse events in elderly acute coronary syndrome(ACS)patients with diabetes mellitus(DM).Methods:The analysis involved 718 ACS patients>80 years old whose general clinical data and baseline blood biochemical indicators were collected prospectively from January 2006 to December *** patients were classified into two groups based on DM status,and then followed up after *** Kaplan-Meier method was used for major adverse cardiac event(MACE)rates and all-cause *** Cox regression was performed to analyze the relationship between UA level and long-term clinical *** operating characteristic(ROC)curves were analyzed to predict the cutoff value of UA in elderly ACS patients with *** were 242 and 476 patients in the DM and non-DM(NDM)groups,respectively,and the follow-up time after discharge was 40‒120 months(median,63 months;interquartile range,51‒74 months).Results:The all-cause mortality,cardiac mortality,and MACE rates in both DM and NDM patients were higher than those in the control group(P=0.001).All-cause mortalities,cardiac mortalities,and MACE rates in DM patients with moderate and high UA levels were significantly higher than those in the NDM group(P=0.001).Long-term survival rates decreased significantly with increased UA levels in the ACS groups(P=0.001).UA(odds ratio(OR)=2.106,95%confidence interval(CI)=1.244‒3.568,P=0.006)was found to be an independent risk factor for all-cause mortality and MACE in elderly ACS patients with *** cutoff value of UA was 353.6μmol/L(sensitivity,67.4%;specificity,65.7%).Conclusions:Serum UA level is a strong independent predictor of long-term all-cause death and MACE in elderly ACS patients with DM.
