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.

The main purpose of this paper is to propose a unsupervised clustering-based method to pre-extract the support vector for training the SVM in light of the theory that the classification facet of SVM is determined by support vector only. By analyzing the limitation existed in current multi-class classification methods, and taking into account comprehensively the separability of the class set of nodes, a hierarchical classification method of SVM binary tree based on tree classifier with optimized overall performance is designed.

针对SVM的分类面仅由支持向量决定的理论，提出一种基于无监督聚类方法来预抽取支持向量，训练向量机；并分析现有多类分类方法所存在的弊端，基于综合考虑节点的类集合可分性，设计一种基于树分类器整体性能最优的SVM二叉树层次分类方法。

In the past research, instruction clustering pay more attension on instruction parallelism, and pass the register pressure to register allocator. In this paper, the authors clustered instruction through runtime inspection of the register command pressure.

在以往的研究中，软件流水之前的指令分簇会更多地考虑指令并行性，往往会把寄存器的压力交给寄存器分配阶段，当物理寄存器不够分配时会造成寄存器溢出。
