Earthquake Engineering and Structural Dynamics(You can input any number of stores by giving the mass, stiffness and damping values. Input the gamma and beta values which are related to Newmark Integration Mtd. Press Newmarks Integration button to input the values. Input the any number of storey that you expected to see the deflection for particular Earthquake. Press “Storey No” button to get that number. If you like only, you will input the period and press “Period” button. Finally press calculate button to see final results. Also you can see the both graphs in log scales also.(Please right click on the graph as shown above). You may see what type of analysis method is used. (Average acceleration relation ship or Linear variation of acceleration).)

双向DCDC的简单电流控制，既可以升压，也可以降压，适合于储能，光伏接入电网(bidirectional dc dc )

很好的分析了大规模MIMO中多小区导频污染问题，并给出了一些可行的减轻污染的方法，值得参考。(Good analysis of large-scale multi-cell MIMO pilot pollution problems, and gives some practical ways to reduce the pollution, it is also useful.)

遗传算法是计算数学中用于解决最佳化的搜索算法，是进化算法的一种。进化算法最初是借鉴了进化生物学中的一些现象而发展起来的，这些现象包括遗传、突变、自然选择以及杂交等。遗传算法通常实现方式为一种计算机模拟。对于一个最优化问题，一定数量的候选解（称为个体）的抽象表示（称为染色体）的种群向更好的解进化。传统上，解用二进制表示（即0和1的串），但也可以用其他表示方法。进化从完全随机个体的种群开始，之后一代一代发生。在每一代中，整个种群的适应度被评价，从当前种群中随机地选择多个个体（基于它们的适应度），通过自然选择和突变产生新的生命种群，该种群在算法的下一次迭代中成为当前种群(Genetic algorithm,GA,SGA)

这是一个用matlab编写的牛顿法源代码，比较简单的无约束方程。牛顿法是求非线性方程（组）零点的一种重要的迭代法，又称牛顿－拉弗森法或切线法。(This is a matlab source code written in Newton s method, relatively simple equation of the non-binding. Newton s method is the pursuit of non-linear equation (group) zero is an important iterative method, also known as Newton- La Fusen law or tangent method. )
