高斯低通/高通频率域滤波实现图像的模糊/锐化(Gaussian low pass/high-pass filtering in frequency domain image of the fuzzy/unsharp)

说明：  基于MATLAB的FIR带阻数字滤波器的设计 由于生物医学信号处理过程中易混入50Hz噪声的特点，本文利用程序设计法和FDATool设计法(Based on the MATLAB FIR digital filters with resistance of biomedical signal processing design due process characteristics of noise, with isolator using the program design method and FDATool design method)

说明：  指纹灰度方差均值的归一化处理~一小段程序~图像预处理(Fingerprint gray variance of normalized mean a short program ~ ~ Image Processing)

QPSK的调制；比较DQPSK和QPSK在通过加性高斯白噪声信道时的误码性能；OFDM系统(QPSK modulation more DQPSK and QPSK in additive white Gaussian noise through the channel bit error performance when OFDM system)

某居民楼共21层，从6：00到9：00，平均有500人出，200人进门，没有人楼层之间窜门，电梯运动通过 一层距离时间为1秒，启动和制动另需1秒，开门关门需要2秒，一个人进出电梯平均时间0。5秒，电梯容量 为15人，呼叫间隔服从指数分布，楼层等概率，上行将乘客送完，下行时有更低楼层呼叫（只要时间允许）就 带走，6：00时电梯在一楼，无乘客停在刚才服务的楼层，一般先先呼叫谁先接受服务，但上行时不接受更低呼叫 下行时不考虑更高楼层呼叫 (a simulation matlabtest for elevator models)

牛顿迭代法求无约束一维极值问题的速度相当快，而且还有一个好处就是能高度逼近最优值。(Newton iteration method for one-dimensional unconstrained extremum problem very fast, but there is a benefit that can be highly close to the optimal value.)

雨流计数法，采用时间轴转成竖直向下，然后依据下雨流水的模式计算各极值，形成局部循环(Rain-flow counting method, using the timeline into a vertically downward, and then based on the pattern of rain water each extremal form a partial circle)
