风电塔架风速时程曲线与风荷载时程曲线模拟。本代码依据IEC 61400-1标准，用于模拟具有一定功率谱密度和自相关性的风速时程曲线，并计算叶片及塔架上的风荷载。方法为基于三角级数叠加的谐波合成法（Hansen，2008）和叶素动量法。功率密度谱采用Kaimal谱函数。(Curves of wind speed and wind load-time curve Cheng wind tower. The code according to IEC 61400-1 standards, and procedures used to simulate the spectral density curve has a certain power the time correlation of wind speed and calculate the wind load on the blades and tower. The method is based on trigonometric series superposition of harmonic synthesis (Hansen, 2008) and the blade element momentum method. Kaimal power density spectrum using spectral function.)

这是我自己编写的一段VDkalman程序，对于研究雷达目标跟踪的朋友应该有点帮助，愿意分享。(This is what I have written for some VDkalman procedures, the study of radar target tracking should be a little friend to help, willing to share.)

LMS算法是一种很有用且很简单的估计梯度的方法。这种算法60年代初得出以后很快得到应用，它的突出优点是计算量小易于实现，且不要求脱线计算。只要自适应线性组合器每交迭代运算时都知道输入信号台和参考响应，那么，选用LMS算法是很合适的。(LMS algorithm is a very useful and very simple estimate of the gradient method. The algorithm reached 60 soon after the early applied, it is to calculate the amount of the outstanding advantages of a small easy to implement, and does not require off-line calculation. As long as the adaptive linear combiner time per each iteration all know that Taiwan and the reference input signal response, then the selection of LMS algorithm is very appropriate.)

A 4 bit twisted ring counter is a sequential circuit which produces the following sequence of output values: 0000, 1000, 1100, 1110, 1111, 0111, 0011, 0001 and then repeats. Design a circuit for a 4 bit twisted ring counter that uses four D flip flops. Draw a state transition diagram, a state table and a schematic for your circuit. Design an alternate implementation using just three flip flops and draw a state transition diagram, state table and a schematic for your circuit. If your designs are extended to implement an n bit twisted ring counter, how many flip flops are required using each of the two approaches. In what situations would you prefer the first method? In what situations would you prefer the second?
