Weighted Fuzzy C-Mean clustering algorithm by one-dimensional histogram can classify accurately pixels of coal flotation froth images into three kinds such as bubble vertex, the bubble surface and the background to increase the contrast of bubble edge and background, accurately positioning the bubble region for its fast convergence speed, real-time characteristics. After de-noised based on morphological...
Interactive System on internet of laboratory center using ASP dynamic web page technology is composed of three modules, namely display module of laboratory center, integrated management module and related query module. Crossing the boundaries of time and space, it built an open management platform of course-arranging and course-selecting on internet. It is this kind of patterns that teachers can interact...
Many wavelet functions produce countless groups of wavelet bases. Every wavelet base has its time-frequency characteristics. There will bring about different results while analyzing the same problem with different wavelet bases. So selection of wavelet base will have influence on quality of fault diagnosis of motor. By analyzing and compare wavelet bases, author has selected the wavelet base which...
The fluctuated thresholds de-noising methods is common as well as good de-noise way in fault diagnosis of motor. The de-noising method with improved fluctuated thresholds has been applied in fault diagnosis of motor in this article. The method is proved that it has good de-noising effect by analyzing concrete example and comparing of data.
