Wavelet Algorithm To Establish The Sugar Content Of The Cotton Fiber Surface Fractal Mathematical Model Analysis Of Cotton Fiber

In this thesis, the theory of fractal has been applied to experimental studies of cotton fiber surface. It is evident that there are statistical self-similarity characteristic on the cotton fiber surface. To research the sugar content of cotton fiber with the help of wavelet algorithm, the fractal mathematics model is set up. As result, quantitative relations between the fractal dimension of cotton fiber surface and its sugar content can be made.The issue is resolved, that the regularity of sugar content and sticking can not be efficiently responded by traditional measurement.In the process of spinning from cotton to yarn, there are some phenomena of lapping top rollers lapping bottom roller and lapping apron, due to unsuitable sugar content of cotton fiber. So it is necessary to measure the sugar content of cotton fiber and prepare to handle high content before spinning for solving above problems. The strict conditions, which are required in measurement, can not be afforded by many cotton mills. Applying the fractal mathematics model, we can estimate the dimension of various kinds of cotton fiber surface, then, make the sample consulting the quantitative relation. In practice, the dimension of raw cotton being estimated can contrast with sample and obtain the information of cotton sugar content. Not only can this method respond the regulation of sugar content, but also it can save more time and more labor, avoid the tedious experiment process. It is more important that the method can increase the rate of production and decrease the production cost.Based on the clarification of fractal and wavelet theories, the thesis discuss the close relation between them and explain that the wavelet is the most applicable way to studying fractal. In addition to, two calculating example, that Fractal Brown and W-M Function model, illustrate wavelet algorithm to be more accurate and its ability of good anti-interference.Making use of MATLAB to set up model, accuracy efficiency and convenient have been improvedThe innovation of the thesis is analyzing the cotton fiber surface in application of fractal theory to analyzing the cotton fiber surface...
