In big data era, the changes of data form, data acquisition and data exchange have increased the difficulty in processing data credibility and isomerism, as a result, it ' s difficult to solve the critical knowledge bottleneck of service combination scheduling model. Service scheduling process, analysis of credibility and functional data acquisition is very important, further more, most of the current...
Due to the permenent magnets on the pulley, metal belt in longitudinal motions is influenced by magnet in the system of metal belt transmission with permanent magnets. If we view the magnetic force as an external stimuli, it will result in transverse forced vibrantion of the metal belt. This article used the Kelvin viscoelastic model at first place, and founded the dynamic model of transverse nonlinear...
According to the logical relations of the 11 interactive safety factors of the Petrochemical Dock system, we used the interpretive structural modeling (ISM) method of system engineering to analyze the relationships among these factors. Based on the deeply analysis, a multi-level stratum structure model that the influence to the safety factors of a petrochemical Dock's system was established. In the...
Aiming at nonlinear control system on-line modeling, the effects of training data distribution to the performance of SVR are analyzed, and a new modeling method based on modified support vector regression (SVR) is proposed. The analyzed results indicate that the data near to the new added sample should be preserved when training data are updated, which can improve the performance; the fixed parameters...
