16 Quam modulation and link budget calulation for SATCOM

本书简绍了matlab编写有限元程序的整个流程(The goal of this document is to give a very brief overview and direction in the writing of nite element code using Matlab. It is assumed that the reader has a basic familiarity with the theory of the nite element method, and our attention will be mostly on the implementation. An example nite element code for analyzing static linear elastic problems written in Matlab is presented to illustrate how to program the nite element method.)

锚杆挡墙的立柱和锚杆内力的有限元分析,可以分析立柱在挡墙土压力作用下的挠曲线，以及内力大小，对于锚杆挡墙的优化设计具有较大作用。(FEM analysis on the internal forces and deflection of beam for anchoring retaining wall)

LMS自适应滤波器与NLMS自适应滤波器的比较(LMS adaptive filter and compare NLMS adaptive filter)

微粒群优化算法，经典的粒子群优化算法，第一参数是适应值函数，因此方便多次使用(Particle swarm optimization algorithm, the classical particle swarm optimization algorithm, the first parameter is the fitness function, so convenient to use many times)

说明：  本程序旨在计算在整个调节时段的初末水位已知的情况下（水位均为170米），从后往前计算出每个阶段的各个水位到最后阶段的最优发电效益，逐步向前递推找出最大年发电效益，从而找到最优化的路径放入到矩阵LJ中，本程序未考虑防洪限制。(The purpose of this procedure is to calculate the optimal power generation benefit for each stage from the rear to the final stage (the water level is 170m) in the case where the initial water level of the whole adjustment period is known (the water level is 170m), and the maximum annual power generation benefit can be found gradually forward. In order to find the optimized path into the matrix lj, the procedure does not take into account the flood control limitation.)

说明：  学会不同搜索法（最速下降法，共轭梯度法，牛顿法，拟牛顿法）的计算步骤(Learn the calculation steps of different search methods (steepest descent method, conjugate gradient method, Newton method, quasi Newton method))
