塔里木盆地主要构造不整合的分布特征及其与对油气成藏的控制作用

塔里木盆地是经历了多个原型盆地发育演化的大型叠合盆地，具有多期构造运动，发育多个区域构造不整合面。通过对构造层序和主要构造不整合分布的研究，总体上可以将塔里木盆地划分为5个一级构造层序和13个二级构造层序；主要构造不整合显示出一定的分布特征，大体从隆起区、斜坡区和坳陷区，常由高角度不整合、微角度或平行不整合到整合接触带。高角度不整合带，对油气的分布、运聚成藏起着一定的促进作用和破坏作用。不整合的发育，可以成为油气侧向运移的良好通道；可以为油气提供良好的储集场所和空间；也可以使先期油气藏遭到破坏和封闭重建，发生二次成藏。阐明不整合界面的特征，可以对分析盆地演化、古隆起古地貌恢复提供有利的依据．对油气的运移、聚集、成藏研究有着重要的意义。     

Finding approximate matches in large lexicons

Approximate string matching is used for spelling correction and personal name matching. In this paper we show how to use string matching techniques in conjunction with lexicon indexes to find approximate matches in a large lexicon. We test several lexicon indexing techniques, including n-grams and permuted lexicons, and several string matching techniques, including string similarity measures and phonetic coding. We propose methods for combining these techniques, and show experimentally that these combinations yield good retrieval effectiveness while keeping index size and retrieval time low. Our experiments also suggest that, in contrast to previous claims, phonetic codings are markedly inferior to string distance measures, which are demonstrated to be suitable for both spelling correction and personal name matching.     

On-Line Shape recognition with incremental training using binary synaptic weights algorithm

Recognition of hand drawn shapes is beneficial in drawing packages and automated sketch entry in handheld computers. In this paper, we propose a new approach to on-line geometric shape recognition with incremental training function, which utilizes a heuristic function to reduce noise and a neural network for classification and on-line training. Instead of recognizing segments of a drawing and then performing syntactical analysis to match with a predefined shape, which is weak in terms of generalization and dealing with noise, we examine the shape as a whole. The main concept of the recognition method is derived from the fact that internal angles are very important in the perceived shape of outlines. Our application's aim is to recognize elliptic, rectangular, and triangular shapes in a way similar to human cognition of these shapes. Human beings recognize such basic shapes regardless of the variations in size, noise on the shape border, rotation and in the case of triangles, regardless of the type of the triangle. The key concept is that the neural network learns the relationships between the internal angles of a shape and its classification, therefore only a few training samples which represent the class of the shape are sufficient. Fast meremental training, which is performed on-line, is accomplished by the use of the Binary Synaptic Weights algorithm, a one pass, feedforward neural network training algorithm. Incremental training offers the advantage of adjusting the recognition capability of the system to the user's drawings. the results are very successful, such that the neural network correctly classified shapes that did not have any resemblance to the shapes in the initial training set.

基于Gabor小波与LBP直方图序列的人脸年龄估计

提出了一种基于Gabor小波和局域二值模式(Local binary pattern,LBP)直方图序列的人脸年龄估计方法。首先对人脸图像提取多方向与多尺度的Gabor幅值域图谱(Gabor magnitude maps,GMMs);然后采用基于局部特征的LBP算子对GMMs编码,并对之分块,由各子块的直方图序列来描述人脸;为进一步降低人脸特征维数,再对人脸直方图序列特征应用主成分分析(PCA);最后使用支持向量机回归(SVR)的LOPO策略对人脸年龄库进行训练和测试。实验结果表明,该方法可以较为快速有效地对人脸图像进行年龄估计。

Ajax技术在Web2.0网站设计中的应用研究

Ajax是Web领域的前沿技术,这种技术提供了新的互联网交互模型,并扩展了Web应用的能力。文中在介绍Ajax技术的工作原理、分析比较Ajax工作模式与传统Web工作模式区别的基础上,运用Ajax技术实现了网页的动态加载,用户的请求能更为迅捷地得到Web应用程序的回应。这样就避免了在网络上频繁地重复发送那些没有更新过的信息。相对于传统的Web应用,Ajax技术在丰富客户端的表现能力、改善用户体验中,表现了强大的交互性能。其原因在于Ajax技术实现了客户端与服务器间的数据通信,并提供了两者间异步通信的能力,因而降低了网络传输的数据量,均衡客户端与服务器间的负载。从而体现了Ajax技术提高系统效率与优化用户界面的优良性能。
