EWMA ( exponential weighted moving average ) control chart models are employed to forecast and estimate the distilled network traffic features, then an early net-worm propagation detection method is presented considering the features of network worm propagation. 采用指数加权移动平均控制图模型对所提取的网络流特征进行预测和估计，并结合网络蠕虫的传播特征给出了一种网络蠕虫的早期检测方法。
This paper selects three typical predictive methods for carrying out load prediction of the same objective building : linear regression ( LR ), seasonal exponential weight moving average ( SEWMA ), and artificial neural network ( ANN ). 针对同一幢建筑，分别采用了多元线性回归、季节性指数平滑法以及神经网络方法等三种典型性预测方法进行负荷预测研究，并对三种方法做了进一步改进。
After building the data pre-processing set before data mining, lots of widely used stock market technical indicators such as the KD indicators, similarities and differences between exponential smoothing moving average MACD, Relative Strength Index RSI, will be introduced into the model. 对数据预处理后得到的数据进行挖掘，将股市中广泛使用的技术指标如KD指标、指数平滑异同移动平均线MACD、相对强弱指标RSI等引入模型。
Another method is jitter buffer based fast convergence method that uses variation of jitter buffer fill level to get the description of the clock difference between the two end clocks, and the double EWMA ( Exponential Weight Moving Average ) filter is used to carry out noise cancellation. 另一种方法则是基于去抖缓冲区的快速锁定的自适应时钟方法，其主要特征是基于缓冲区变化量得到时钟差异的描述信息，并利用两级EWMA滤波完成噪声的消除。
The reason results in that small fault is difficult to be detected lies in the large noise of measured data and Exponential Weighted Moving Average ( EWMA ) filter is proposed to improve the ability of small fault detection. 分析认为造成传感器小故障难于检测的原因在于测量数据的噪声太大，并提出采用指数加权滑动平均滤波器来提高系统小故障检测能力的方法。
