PCAxmeas_fault1
说明: 主元分析方法(PCA)是一种基于多元统计分析的数据降维方法, 它利用过程变量间的相关关系, 建立正常工况下的主元模型, 通过检验新的数据样本相对于主元模型的背离程度, 从而发现异常和故障。 (Principal Component Analysis (PCA) is based on multivariate statistical analysis of the data reduction method, which uses the correlation between process variables and establish the normal condition of the main element model, by testing samples of the new data relative to the principal component model departure from, and thus abnormal and failure.)

2D-logistic-image-encrytion
本matlab函数,利用混沌映射不可预测性,遍历性和敏感性,以它们的参数和初始值的优异特性的,实现一个图像加密算法。我们引入了一个新的二维logistics函数。与现有的混沌映射相比,它具有更广泛的范围内混乱,更好的遍历性,混沌性和relativelylow实施成本。为了研究及其应用,我们提出了一个之乱转换(CMT),以有效地改变图像的像素位置。结合2D-logistics与CMT,我们进一步实现图像加密算法。(In this matlab test,we use the chastic s excellent properties of unpredictability, ergodicity and sensitivity to their parameters and initial values, chaotic maps are widely used in security applications. In this paper, we introduce a new two-dimensional Sine Logistic modulation map (2D-SLMM) which is derived the Logistic and Sine maps. Compared with existing chaotic maps,it has the wider chaotic range, better ergodicity, hyperchaotic property and relativelylow implementation cost. To investigate its applications, we propose a chaotic magic trans-form (CMT) to efficiently change the image pixel positions. Combining 2D-SLMM with CMT, we further introduce a new image encryption algorithm. )

说明: 针对小流域设计洪水计算中,采用推理公式求解洪峰流量Qm及汇流时间τ的方法繁琐,查算精度较低等问题,提出用牛顿迭代法求解,该方法较原图解试算法收敛快,迭代次数少,计算速度快,精度可靠。计算实例表明,用简单迭代法与牛顿迭代法计算设计洪峰流量,其结果与图解试算法完全一致。()
