The gestation and occurrence of strong earthquakes are closely related to fault activity, which is not only revealed by abundant experimentation and seismism but also proved by modern seismology. On the Chinese mainland, the relation between earthquake

Using function one direction S-rough sets (function one direction singular rough sets), f-law and F-law and the concept of law distance and the concept of system law collided by F-law are given. Using
A new algorithm is proposed for completing the missing parts caused by the removal of foreground or background elements from an image of natural scenery in a visually plausible way. The major contribu
分形压缩技术存在很多优点,但其还存在编码时间过长的缺点.理论已经证明IFS不会改变图像块的熵值.本文提出了一种基于改进熵值的分形压缩算法:一是采用改进的熵值进行判断,降低了算法的复杂度,二是通过合并定义域池使编码时间减少.实验结果表明,采用该方法时的编码时间和PSNR较其他算法有明显提高,压缩比也有所提高.
通过研究温度和NaCl对两种藜科叶肉质化盐生植物——里海盐爪爪和盐爪爪种子萌发的影响,显示出里海盐爪爪的最适萌发温度范围为20~30℃,而盐爪爪适合在变温条件下萌发,两者对温度的反应有显著差异;两者的萌发率和萌发速率都随NaCl浓度升高而降低,里海盐爪爪比盐爪爪的耐盐能力低;高盐分条件能诱导两个种的休眠,而当盐浓度降低时两者都能很好地恢复萌发,且萌发速率加快。因此,尽管里海盐爪爪仅能在低于300m
21世纪是一个网络化、数字化的信息时代。如今,能够帮助教练员获取各种体育技术、信息的最快捷方式之一,就是来自于——网络。过去那种文字、图片等资料形式已经满足不了当今三维式教学、训练的需求;因为只有动态的(视频的),才是表达最直观的和现实的。
In computer aided geometric design(CAGD) ,it is often needed to produce a convexity-preserving interpolating curve according to the given planar data points. However,most existing pertinent methods ca
This paper presents some techniques for synthesizing novel view for a virtual viewpoint from two given views cap-tured at different viewpoints to achieve both high quality and high efficiency. The who
Iris recognition,as a biometric method,outperforms others because of its high accuracy. Iris is the visible internal organ of human,so it is stable and very difficult to be altered. But if an eye surg
The tectonic characteristics and research problems of five earthquakes with M≥7.0 on the North China Plain over the last 300 years are addressed in the paper, including the cognition that there were n
The author carefully selected earthquakes with M_L=4.0～5.0, 215 occurring in the crust in the Taiwan region. The attenuation characteristics of maximum displacement recorded by the Fujian digital netw
