In this thesis, the application of combined hybrid method to axisymmetric elasticity problem and the optimization of combined hybrid axisymmetric finite elements are discussed in a manner of combination of mathematical analysis with numerical investigation. 本文从理论分析和数值实验的角度研究了组合杂交法在轴对称弹性力学问题上的应用和加权系数优化的原则。
A niche hybrid genetic algorithm is proposed to solve this problem effectively while avoiding the complicated dynamic sensitivity analysis. 本文提出一个简单实用的小生境混合遗传算法,避开繁琐的动力灵敏度分析,有效地进行隔振器的瞬态优化设计。
In the mean time, impulsive systems can be seen as hybrid systems which are composed of continue-time subsystem and discrete-time subsystem, the problem of stability analysis and controller synthesis for impulsive systems is an important topic in automatic control. 同时,脉冲系统可以看成由连续子系统和离散子系统组成的混合系统,对其稳定性分析和控制器设计一直是控制理论研究的一个重要课题。
A certificateless hybrid encryption scheme based on elliptic curve discrete logarithm problem is proposed. We analysis the proposed scheme in public-key security and message confidential security. In the proposed scheme the main operations is point operation in elliptic. 本文提出了一个基于椭圆曲线离散对数的无证书混合加密方案,并对提出方案的公钥安全性和消息保密性进行了分析。
