互连矩阵最小完全集的一种应用

本文提出了互连矩阵的最小完全集的概念，揭示出平面ＶＬＳＩ脉动阵列的各种连接方式的内在联系，并将这一概念运用于脉动阵列的设计过程，使求解空间超平面的计算复杂性大大降低，从而提高了以数据相关──超平面法自动设计ＶＬＳＩ系统的可行性。

On the Compact Spacelike Hypersurfaces in de Sitter Space

In this paper, two properties of compact spacelike hypersurfaces in de Sitter space are obtained. When r =1, we recover Montiel's result.

基于微粒群算法的LS-SVM时间序列预测

将微粒群算法引入到最小二乘支持向量机(LS-SVM)时间序列预测,建立预测模型。思路来自微粒群算法可以在超平面空间中实现优化搜索,因此,将微粒群算法中的微粒运动公式进行修正,从而实现对LS-SVM的训练。然后用训练过的LS-SVM进行预测,即得到最终结果。将此方法应用于销售量预测,结果表明,此模型有更高的预测精度,而且在不同的LS-SVM学习参数下模型的误差相对稳定。

Hypersurfaces with Constant Mean Curvature in Space Forms

In this paper,we study the pinching problem for a hypersurface with constant mean curvature in space forms to be totally umbilical by osing the relationship between the square of the length of the second fundamental form and the mean curvature. We obtained a best pinching interval and decided the complete classification of hypersurfaces at the terminal of the interval.This improved the relative results of M. Okumura,Shen Yibihg and Sun Ziqi,etc.

Rigidity Theorems for Hypersurfaces in Real Space Form

In this paper, a rigidity theorem of hypersurface in real space form will be given. In addition, we obtain rigidity theorems of submanifold in sphere which improve the result of Hou and Xu.

Curvature Estimates of Hypersurfaces in the Minkowski Space

A class of curvature estimates of spacelike admissible hypersurfaces related to translating solitons of the higher order mean curvature flow in the Minkowski space is ob- tained, which may offer an idea to study an open question of the existence of hypersurfaces with the prescribed higher mean curvature in the Minkowski space.
