Characteristics of the Internet traffic data flow are studied based on the chaos theory. A phase space that is isometric with the network dynamic system is reconstructed by using the single variable time series of a network flow. Some parameters, such as the correlative dimension and the Lyapunov exponent are calculated,and the chaos characteristic is proved to exist in Internet traffic data flows. A neural network model is constructed based on radial basis function to forecast actual Internet traffic data flow.

摘 要：应用混沌理论，分析了网络流量，用单变量的网络流量时间序列重构与网络动力系统等距同构的相空间，进而计算了实际网络的关维数和Lyapunov指数，并证实了网络流量存在混沌特性；据此建立了基于径向基函数神经网络的模型，并对实际网络数据流进行了预测。

Based on the theory proposed by Alkhalifah, that is the reflection wave is determined by normal moveout velocity V of short-spread and anisotropic parameter η under the condition of long-spread data of vertical and lateral isotropic media and non-hyperbolic curve, a method for long-spread data velocity analysis is studied. A 2 step scanning method is used for the hyperbolic and dual parameter scanning of long-spread data.

Owing to the test of fatigue life,possesses a rather big difficulty and its testing data have the characteristics of strong scatterence and if a prediction is made from using grey-forecasting model GM(1,1,thus its prediction value would get a rather big error compared with the real result,This paper hereby put forward a kind of new method to simulate the test.let the data be firstly processed into logarithmic series so as to reduce the scatterence of data,and then carry out the prediction by the use of grey-forecasting model.

由于疲劳寿命试验具有难度较大，其实验数据具有分散性强的特点，如果直接用灰色预测模型（GM（1，1））作预测，其预测值与真实结果的误差较大。在此提出一种试验仿真的新方法。首先将数据处理成对数序列，以降低其数据分散性；然后再用灰色预测模型进行预测。

I will introduce a method to solve this problem when data come from some common life distribution, such as Weibull distribution and Lognormal distribution. In chapter 1, we introduce background of grouped data and how to analyze them with classical methods. In chapter 2, we introduce EM algorithm and show that the estimation of the parameters get through this algorithm is convergent under certain conditions. In chapter 3, we use EM algorithm to estimate parameters in Weibull distribution and Lognormal distribution by grouped data and the simulation shows this method is available.
