The Support Vector Classification (SVC) model was constructed in this study by applying the near infrared (NIR) analysis technology combined with the chemometrics method to classify and distinguish 11 types of vegetable oil, including "restaurant waste oil". Partial least squares-discriminate analysis (PLS-DA) and GA-SVC classification models were constructed, respectively, after the data...
In recent years, major projects are becoming risk sources to social instability, which have triggered many mass incidents. High-risk society changes evaluation criteria and agenda of project decision-making. By introducing risk society theory into social impact assessment on major projects, a model of “cognition-behavior” is established to modify the assessment criteria and discipline, and also a...
In alloy bar rolling by Round-Oval pass sequence, the critical point on the contact boundary is solved and the cross-section profile parameter of outgoing workpiece is represented, then the equivalent height of outgoing workpiece and mean roll radius at the exit section is derived to correct the spread formula. Based on the initial spread calculated by the modified Shinokura and Takai spread formula,...
A prediction model of compression ratio for extruded oilseeds was developed based on improved BP neural networks. As an applied example, the predicted curves were successfully used to predict critical pressing pressures. Results indicated that the predicted values of compression ratios conformed to the measured values well for extruded cottonseed and castor been. There was a limiting compression for...
