FDTD 远场计算

基于bpa的IEEE39节点算例，包含暂态数据和稳态数据(Example of IEEE39 node based on BPA)

说明：  采用Python脚本语言二次开发ABAQUS的前处理模块创建了一个带孔平板模型，实现了参数化建模。(Parametrical model using Python in Abaqus.)

说明：  北京航空航天大学航智能控制第二版配套的仿真程序(Simulation program of intelligent control Second Edition from Beijing University of Aeronautics and Astronautics)

并联机器人的运动学动力学分析以及轨迹规划(Trajectory planning, kinematics and dynamics analysis of parallel robot)

说明：  These composite materials generally exhibit brittle damage behavior. The anisotropy in the material and different kinds of failure mechanisms make it difficult to accurately characterize the behavior of composite materials. The present work aims to verify and apply the Puck Failure Criteria using the commercially available finite element package ANSYS by writing a user-material subroutine in FORTRAN. The model is implemented with different post failure degradation schemes EWM/CSE.

说明：  用来模拟光学中各种孔径的菲涅耳衍射和夫琅禾费衍射，清晰明了(It is used to simulate Fresnel diffraction and Fraunhofer diffraction of various apertures in optics. It is clear and clear)

说明：  基于信噪比的协作频谱感知算法，能量检测。信噪比(Collaborative Spectrum Sensing Algorithm Based on Signal - to - Noise Ratio.Energy detection.Signal - to - Noise Ratio.)

蓄电池双向Boost/Buck充放电控制，与电网结合。(Battery bi-directional Boost/Buck charge and discharge control, combined with the grid.)
