In chapter 4, the Newlands harmonic wavelet is improved and a new type of wavelet with better time-frequency characteristic is constructed. Frequency band of signal can be divided arbitrary with the improved harmonic wavelet so that the phenomena of aliasing are reduced. Several typical fault signals in Electromechanical System are analyzed with it. In addition to the improved harmonic wavelet in chapter 4, a new half-complex wavelet is presented to improve the complex wavelet, which is given by Chaari.O. A unilateral recursive algorithm is derived to improve the real-time characteristic. A parameter n is imported to make the time-frequency and filtering characteristics of it better and its ability of extracting fault feature is enhanced.

Luhrmann's soft-filtering lens — a man being trampled to death by rampaging cattle or a city being annihilated by bombing Japanese warplanes — the calamities of history are merely colorful grist for his main interest, the romance between a wilted English rose, Lady Sarah Ashley, and an itinerant Australian cattleman, the Drover. The lady and the tramp meet soon after she lands in Australia to track down her cattleman husband, whose early murder sets all the narrative pieces in place. Initially intent on selling her property, including 1,500 head of cattle, Sarah soon transforms into a frontierswoman, seduced by Nullah's smile and the majestic valleys and peaks of both the land and of the Drover's musculature.
