查询词典 hurst

According to fractal theory, R/S analysis on the typical colluvial landslides is complete, finding that the parameter of Hurst decreases just at the time before the landslide took place. This research result shows that Hurst parameter is an effective nonlinear displacement parameter and it also has a very explicit forecast function.

By sampling from the traffic flow and averaging non-overlapping blocks of size m from the original series, the variance asymptotic characteristic of the averaged series is obtained, from which this method shows that the splitting, assembling and merging process of the convergence mechanism will not change the Hurst parmeter of the traffic if the queue length of assemble buffer has a finite second-order moment.

在分析光突发交换边缘结点汇聚机制的基础上，提出了一种基于方差时间图的分析方法，利用"时间离散"和"尺度聚集"的思想，通过构造不同聚集级别m的聚集序列，分析得出业务流时间聚集序列的方差渐近性，从理论上证明了在组装器队长具有有限二阶矩的条件下，汇聚机制的分解、组装和合并过程不会改变业务流的Hurst参数。

Secondly, a series of computer programs have been developed and verified according to the deterministic chaos theory and algorithms. These programs are deterministic chaos qualitative analysis tools including phase plots and Poincare section analysis software packages; deterministic chaos quantitative analysis tools including the largest Lyapunov exponent, correlation dimension and Kolmogorov entropy analysis codes and classical analysis such as power spectrum, autocorrelation coefficient and Hurst analysis programs.

其次，根据确定性混沌分析技术主要内容的算法思想，自行开发了相图、Poincare截面等定性分析程序软件包；最大李雅普诺夫指数、关联维数和K熵等定量分析程序软件包以及非线性混沌预测程序软件包；同时，还开发了功率谱、自相关系数、Hurst指数等传统分析技术程序软件包；并运用三种典型的周期运动、混沌运动及随机运动时间序列数据，验证了开发的程序。

The long memory of time series array firstly was found by Hurst in 1951, and then was established mathematical foundation by introducing fraction Brownian movement and conception of fractal by Mandelbrot.

时间序列的长记忆性，最早是由水文学家赫斯特于1951年提出来的，之后又由Mandelbrot引入分数布朗运动以及分形概念为之建立了严格的数学基础。

"Infact,Robert was my brother,2 years elder than me.he always take me here,to visit this old chinar,he call him 'king of the hurst'.each time ,he will repeat the same work——to climb on the oak,and call it as 'conquest'.

其实，罗伯特是我的哥哥，比我大两岁。他常常带我到这来，看望这棵老梧桐树，他称他为'森林之王'。每次来这，他都会重复同样的事情——爬到树上去，他称之为'征服'。

Then an adaptive, efficient unbiased estimator of Hurst index based on multiresolution wavelet analysis and weighted regression is presented.

针对基于小波的Hurst指数估计方法的自适应问题，结合方差分析给出了一种有效的解决方法，从而提出了自适应的参数估计方法，并且该方法在一般意义上是无偏的。
