Manufacturing resources model is the most important part of virtual manufacturing. This study demonstrates the information expressing model of manufacturing resources, which can be separated into virtual control model, real model and functional model of virtual manufacturing devices. The study also indicates the relationship among three parts and presents the modeling methods.
In the past, the gene effect causing the variation of quantitative trait was researched as a whole body. For avoiding the QTL mapping, the molecular marker regression was used to research the quantitative trait controlled by polygene. A general analysis model using molecular marker material was established for estimating the gene effect controlling quantitative trait, and the mathematical relation...
Aim at the foreign randomicity and the color difference between the regular material and the foreign in high speed real-time foreign recognition, an approach to real-time foreign recognition based on hypersphere one-class support vector machines is presented. In this method, regular material are considered as training samples, and OC-SVM is used to obtain the color distributing of the regular material,...
In order to get the relationship between conductivity or polarization and electric field and to measure the capacitive current and the resistive current respectively, under periodic wave, a decomposition method is proposed. The leakage current can be decomposed to get the relation between conductivity or polarization and electric field. Under periodic stimulation, and by making use of the change of...
Based on the data from the fatigue test of Epoxy Molding Compound (EMC), firstly with a focus on the application problem of the instability between fitting and prediction error of BP neural network (BPNN), the prediction model of fatigue life for EMC materials is established. In this approach, the network structure is improved with initiative way by reducing input from the perspective of nodes with...
