Based on the horizontal deformation field and the strain field derived from the GPS data over the period of 1999～2001 in the Yunnan area, the characteristics of deformation and strain in the northern part of Yunnan Province have been studied. The resul

To solve the arrearage problem that puzzled most of the mobile corporations, we propose an approach to forecast and evaluate the credits for mobile clients, devising a method that is of the coalescenc
二维最大熵图像分割算法充分利用了图像象素的灰度分布信息和各象素间的空间相关信息 ,因此具有很好的分割效果。但该算法的计算复杂度高、计算时间长。为解决这一问题 ,本文提出了一种基于遗传算法的二维最大熵法。该算法充分利用遗传算法的特点 ,极大地减少了计算量和存储空间。实验结果证明了该算法的快速性、有效性和稳定性。
结合生物物理、分子遗传学和细胞生物学的方法已证实,光敏色素信号转导是一个空间分布的、非线形信号传递链。尤其是最近又发现了不同种类的光敏色素分子及其它们在Pr、Pfr光转换中产生的中间体,不仅说明了光敏色素信号转导链是一个多维的信号网络,而且这也暗示着光转换中产生的中间体也直接参与了早期的信号转导。在此,综述了光敏色素分子光转换及其早期信号转导的若干新进展,讨论光敏色素原初光反应及其信号转导的机制。
根植区域生长法(Seeded Region Growing)是处理图象分割的一种快捷的半自动算法([1],R.Adams and L.Bischof,1994),也是目前处理图象问题的一种公认的有效方法和技术.边界像素对该算法的行为及效果有着微妙的但却是重要的.在应用中我们发现,当分割块处于狭窄连通状态时,这一算法常常是失败的,而失败的结果通常会导致原始图象的细节失真或者过分地依赖种子的选择.针对
