decision rule acquisition and knowledge reduction on information system with continuous condition attributes 连续值域信息系统的规则提取与知识约简
the aims of this thesis are researching some typical nurbs surfaces " geometric continuous conditions and pointing out the effects of knot vector and the degree of surface on geometric continuities 本文的目的是研究一些典型的nurbs曲面的几何连续条件,指出节点向量和曲面片的次数对几何连续性的影响。
moreover, this thesis offers the mothod of generate smooth nurbs surfaces over arbitrary quadragulation . this mothod overcomes the defects of adopting so called simple collinear continuous condition to deal with the problem of geometric continuity 并针对任意拓扑的四边形剖分,给出了构造光滑nurbs曲面的方法,克服了采用所谓的简单共线法处理几何光滑连接的缺陷。
in discrete condition, considering two cases of independent identical distribution and dependent distribution, we gave the moment, the second moment and variance, in continuous condition, models of the random rate of interest were established respectively by gauss process, wiener process or o-u process 对于离散型情况,考虑了独立同分布和非独立两种情形,分别给出了给付现值的一、二阶矩和方差。
interest randomness in life insurance has been paid attention to in recent years on actuarial theory and its application, in this paper, n-year linear increasing payment life insurance with the stochastic interest with discrete and continuous condition was discussed 寿险中的利率随机性问题,是近年来寿险精算研究的热点之一。本文在随机利率下对n年期线性增额寿险分离散型和连续型两种情况分别进行了讨论。
