For single edge detection methods causing important and weak gradient change edge missing problems, this paper adopts the method of combining global with local edge detection to extract edge. The global edge detection can obtain the whole edge, which uses adaptive smooth filter algorithm based on Canny operator. Compared with effect of edge detection from(More)
In this paper, the second generation wavelet transform and envelope demodulation method combining solve motor bearing fault diagnosis. Firstly, the bearing vibration signal is decomposed into three layers by the second generation wavelet packet transform with predicted and updater. Then We reconstruct the signal which has faulty characteristics. and we(More)
For trust in software, developers spend much effort debugging to ensure that software behaviors as expected. Spectrum-based fault localization techniques (SFL) make use of runtime coverage of program elements, like statements, branches and du-pairs, and then check codes in the order of the rank of suspiciousness. So, correct elements with higher(More)
Visual effect and fusion quality of the traditional image fusion method is relatively poor. Compressed Sensing (CS) as a new image fusion method is proposed, which is simple and easy to implement. At first, the method uses wavelet transform to the original images and gets sparse matrix by sparse processing of wavelet coefficients. And then coefficient(More)
For the Characteristics of missile during flights with nonlinear and coupling and dynamicity, a kind of adaptive fuzzy PID hybrid control strategy is designed, which is used to control the missile attitude motion. In order to more accurately reflect changes in the vicinity of the error rate of zero, the use of fuzzy sets detailed rules for the program(More)
