少发故障的寿命分布拟合
首先是针对无或单失效数据情形下，通过多层贝叶斯估计法得到失效概率过后，给出了寿命分布参数的加权最小二乘估计。然后如果失效数据不止一个，使用乘积限估计法来得到失效概率的估计值。(Firstly, the weighted least squares estimation of the life distribution parameters is given by the multi-layer Bayesian estimation method after the failure probability is obtained for the case of no or single failure data. Then if the failure data is more than one, the product limit estimation method is used to obtain the estimated value of the failure probability.)

基于FIR带通滤波器的谱峭度编程
应用背景
现代工业通用机械都配备了相当数量的滚动轴承。一般说来，滚动轴承都是机器中最精密的部件。通常情况下，它们的公差都保持在机器的其余部件的公差的十分之一。但是，多年的实践经验表明，只有10%以下的轴承能够运行到设计寿命年限。而大约40%的轴承失效是由于润滑引起的故障，30%失效是由于不对中或“卡住”等装配失误，还有20%的失效是由过载使用或制造上缺陷等其它原因所致。
关键技术对于非平稳信号的谱峭度是关于频率和频率分辨率的函数，因此基于FIR带通滤波器的快速谱峭度算法将其成功的应用于实际的故障诊断之中。此算法是基于二叉树状滤波器组结构的。

IJERTV1IS7260
DC power is steady and continuous, with an electrical charge that flows in only one direction. When the output of DC power is represented on a graph, the result would be a straight line. AC power, on the other hand, flows back and forth in alternating directions so that, when represented on a graph, it appears as a sine wave, with smooth and regular peaks and valleys. A power inverter uses electronic circuits to cause the DC power flow to change directions, making it alternate like AC power. These oscillations are rough and tend to create a square waveform rather than a rounded one, so filters are required to smooth out the wave, allowing it to be used by more electronic devices.
