Numerical Techniques Used in Modeling Codes for Dual-Reflector Antenna Design and Analysis

An user-oriented computer software consisting of three modeling codes, named DRAD, DRAA and FDPAT, is introduced. It can be used to design three types of Cassegrain system: classical, with shaped subreflector and with dual shaped reflectors, and to analyse radiation patterns for the antennas. Several mathematical models and numerical techniques are presented.

马克思主义的矛盾理论是研究和变革社会复杂系统的指南

十九世纪中叶以来,共产党人以马克思主义的矛盾理论为武器,从事探讨和变革人类社会的实践,取得了社会主义运动的许多伟大胜利。反过来又不断丰富和发展了矛盾理论。历史已经证明,马克思主义的矛盾理论是研究和变革社会复杂系统的指南。     

下层为多目标的两人两层决策问题的模型及优化方法

本文针对上层为单目标,下层为多目标的两人两层决策问题,建立了它的数学模型和决策机制,然后将其转化为单层的非凸优化问题。采用外部逼近算法求解此非凸优化问题的全局最优解,这为两层决策问题提供了一种求解的途径,同时为该类问题的决策支持系统的研究是有意义的。
