The polymerization rate of vinyl acetate is extremely important qualitative index and processing parameter, but it is inconvenient being measured directly and real-timely, therefor, in this paper, soft sensor modeling method based on Least Square SVM(LS-SVM)is proposed and cross validation method is used to select hyper-parameter of LS-SVM model. It is applied to the soft sensor of the vinyl acetate...
Although unique properties such as creation of nondiffracting beams and as a result the large focal depth have been exhibited from axicon lenses, and numerous important applications in optical signal processing and imaging have been demonstrated, axicons of dimensions smaller than a hundred of micrometers have not yet been reported. It is technically quite challenging for the currently available technologies...
