Rapid tooling (RT) technology can effectively improve the production efficiency and market competitiveness of enterprises, but the forming process of RT is influenced by many factors, which is a typical weak theoretical strong experience field, How to introduce the expert knowledge and experience into RT forming process is the key to improve product quality. However, due to lack of the information...
With the fast development of Chinese high speed railway, the demand for the maintenance of railway equipment has increased rapidly. This paper studies an intelligent diagnosis method for high-speed railway turnout based on the support vector machine. We focus on the study about the methods of generating the feature vector and propose a rule-based method that utilizes the experts' experience knowledge...
An in-depth study of the multi-classification SVM is given, and the expression classification method based on SVM is proposed for the defects of the traditional classification methods. It realizes fast classification with a relatively small sub-classifier combination, reducing the classification error. Experiments show that the multi-classification method based on SVM can obviously reduce the training...
This paper introduces a novel steganography-based approach to protect the iris data by hiding it into a digital image for personal identification purpose. Logistic map is utilized for generating two pseudorandom sequences, one for encrypting the biometric data before hiding, and another for hiding position encryption. Meanwhile, JND (Just Noticeable Difference) model and JPEG quantization table are...
Near-replicas of web pages have seriously decreased the efficiency of search engine (SE). In this paper, we present a new method to detect near-replicas of web pages. Firstly, the styles of text structures in web pages are analyzed and classified; then according to the styles of the text, different methods are used to get the text structure, which will be represented as a matrix; Finally, the similarity...
This paper is about subdividing of women's breasts based on 3D interactive anthropometric scanning technology. 270 young ladies, aged between 18 to 30 years old, were measured by 3D interactive anthropometric scanner. 11 Characteristic indexes such as breast midriff girth, breast girth items of females' bosom are extracted from 35 variables, which are the decisive factors to determine the tight fashions'...
