Compared with the previous model , the most important advantage of this improvement is that the close - open operator is used in the diffusion process , giving a good trade - off between noise removal and edge preservation 主要的想法是在中值曲率驱动方程模型中结合闭开算子,在较好保护边界的前提下,增强方程的去噪能力,达到去噪和保护边界的一个平衡。
Based on the pim , the closed - loop and closed - open - loop control algorithm under the instantaneous optimal control strategy are acquired , so it has practical significance in active control . at last , the simulation analysis of numerical examples demonstrate that the methods are superior to the conventional numerical methods , and has excellent precision , efficiency and stability 最后,在c + + builder环境下编制各算法程序,算例仿真结果表明,本文算法优于经典数值解法,有很好的计算精度、效率及稳定性,且精度易于控制;同时,用精细积分下结构控制算法进行结构控制模拟,得出较理想控制效果。
This article does some researches on the three typical structural models of human intelligence network named as " strong - weak tie " model , " structural hole " model and " close - open " model , then discusses their characters , use scope , and how to use them more appropriately to serve for enterprises 摘要文章对“强关系弱关系”模式、 “结构洞”模式和“闭合开放”模式等三种典型的人际情报网络的结构模式进行了研究,分析了三种模式的特点和使用范围,探讨了如何运用它们更好地为企业服务。
