In this regard, the research trend of globalization of competition has been positively open up. In this paper a novel simulated annealing feature uniformity band selection approach is proposed for the feature extraction of the hyperspectral remote sensing images. The simulated annealing band selection method has been successfully applied to the feature extraction of the hyperspectral images by clustering highly correlated hyperspectral bands into a smaller subset of band modules based on simulated annealing algorithm. SAFU built by SABS is an efficient feature extraction method.

本篇论文提出一个新型的模拟退火特徵齐一化波段选取法应用在高光谱遥测影像的特徵萃取，模拟退火波段选取法已经成功的应用在高光谱影像的特徵萃取藉著群集高度相关的高光谱波段将之形成一个基於模拟退火演算法波段模组的子集合，本文提出之SAFU是建立在SABS之上，利用旧有SABS的特性加以改良，提出SAFU来对於高光谱影像可以更有效率的进行特徵萃取。

Characteristics and principles of time clustering and frequency with a seismic sequence of more 380 years (1615 —1998) are performed using fractal theory and rescaling range analysis theory. It is concluded that the fiactal dimensions of seismic subset are similar to each other, the mean value is about 0.405, and interval of scale invariance can change 1-2 magnitude order. It is also found that the Hurst index ranges from 0.5412 to 0.5580. The results show that there is of statistical self-similar among different magnitude earthquakes in the area of bridge site.

应用分形理论和R/S分析原理，编写了程序，分析和研究了桥址区的380多年（1615～1998）地震序列的地震时间从集和地震频度特征及规律，得出桥址区不同震级范围的子集合具有近似相等的分维值，约为0.405，子集合无标度区可跨1～2数量级；不同震级层次的地震频度Hurst指数为0.5412～0.5580，都表明了桥址区不同震级层次的地震之间具有统计自相似性。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
