The precision of the non - contact testing of flywheel gear ' s contour and location error of light electricity inspection machine based on virtual instrument has been carried on theory analysis in this paper . various contour and location tolerances of the part have been distributed depending on the result of the analysis , and the data handling method of measurement has been studied to find a data handling method of getting rid of the system error under one kind of condition of the big sample space 本文对飞轮齿圈形位误差光电检验机的精度进行了理论分析,依据分析的结果分配了零件的各种形位公差,并对测量结果的数据处理方法进行了研究,找到了一种在大样本空间的条件下依概率排除系统误差的数据处理方法,同时为了验证其可靠度对其进行了计算机仿真实验。
It has the important influence on detection rate , false positive rate and ability of real time responds . so this thesis labors over kdd cup 99 intrusion detection data set and uses some rules to reduce the dimensions of feature sample space in the derection of sbg . thus the phenomena of dimension exploding can be avoided 特征提取是入侵检测的关键,对检测率、误报率和实时性有着重要影响,因此本文在针对kddcup99入侵检测数据进行了大量分析,并沿sbg的搜索方向,使用一定的规则集来达到特征样本空间的维数的削减的目的,从而避免了“维数爆炸”的现象。
In this paper , the notion of likelihood ratio , as a measure of deviation between a sequence of the arbitrary random variables and a sequence of independent random variables with different distributions , is introduced . a class of strong deviation theorems represented by inequalities are given on a subset of the sample space by constructing a negative supermartingale and using martingale convergence theorem 本文通过引进似然比作为相依随机变量序列相对于服从不同分布的独立随机变量序列的偏差的一种度量,并通过构造一个非负上鞅,利用鞅收敛定理给出了样本空间的一个子集上的一类用不等式表示的强偏差定理。
In connection with the difference and distribution characteristic of the samples in sample space rs based on dga , a new self - adapted weight fuzzy omean clustering model of fault diagnosis of the power transformer based on the potential function is proposed . meanwhile , from the aspect of geometry characteristic of fc - divided in s dimension sample space , a method is proposed for the purpose of getting an effective adjacent radius , adaptive cluster number c and original cluster center of x sample set . for the diagnosis sample x , the property measure and diagnosis rule are proposed , which under the condition of potential density function that determine c number of optimal fuzzy cluster p1 根据以变压器dga数据为特征量的样本空间各样本差异特性以及样本在空间r ~ s的分布特性,首次提出了基于势函数自适应加权的变压器绝缘故障诊断的模糊c -均值聚类模型;同时,从s维样本空间的f ~ c -划分几何特性出发,提出了一种求取样本集的类势有效邻域半径和自适应求取聚类数和聚类中心初值的方法;对一个待诊断样本,设计了基于类势密度函数意义下的属性测度和诊断准则。
