We describe some recent progress in the study of moduli space of Riemann surfaces in this survey paper. New complete Kah......
Let M be a compact Riemann manifold with the Ricci curvature ≥ - R(R = const. 】0). Denote by d the diameter of M. Then t......
Fingerprint feature extraction is a key step of fingerprint identification. A novel feature extraction algorithm is prop......
通过对曲面的Gauss像的讨论证明了:如果X(M)的Gauss像位于一个开半球内,则x(M)是稳定的.接着又讨论了n=2时的情况,通过对共形变换G......
本文计算了沿不同曲面流动的湍流边界层。提出了考虑曲率影响的双方程湍流模式。通过与实测的穿过边界层的湍流能量和结构系数分布......
本文引入曲率参数,描述了分段三次Bezier插值样条曲线(开的和闭的)。这些插值曲线是G~2-连续的和保凸的,并且这些曲线可以作局部修改。最后,用本......
