查询词典 multiple correlation coefficient

In real flight, multiple sensors of aircraft engine control system may fault at a time. In order to solve this problem, a revised multiple-failure-hypothesis based testing is investigated. This approach uses multiple Kalman filters, and each of Kalman filter is designed based on a specific hypothesis for detecting specific sensors fault, and then uses WSSR (Weighted Sum of Squared Residual) to deal with Kalman filter residuals, and residual signals are compared with threshold in order to make fault detection decisions. The simulation results show that the proposed method can be used to detect multiple sensors soft failures fast and accurately.

It indicated that the multiple-layered films were mainly composed by C-F, C=C and Si-O bonging, a little Si-C and Si-F bonding were also existed because of history effect. The bondgap were calculated as 2.7eV. The dielectric constant of the multiple-layered films was close relative to the thickness of the covering layer-SiOx, so the thickness had better be reduce. The bonding configurations of multiple-layered films had no evident changes after 400癈 annealing, the thickness raise very little and the dielectric constant increase 8%. Compared with one-layered a-C:F films prepared in the same conditions, the SiOx/a-C:F/SiOx multiple-layered films had a better thermal stability.

An optimum multiple strain and processing test condition for producing micro-ecological, multiple enzyme feedstuff from beer grain with solid state fermentation was selected by using analytic hierarchy process. Meanwhile, data dispose and weight analyses to the relevant relations of all factores effecting the selection of the scheme were done after setting up a matrix. Multiple weight value of scheme X in target were X1=0.26, X2=0.41,X3=0.33 respectively, so that the optimizing multiple strains and relevant processing conditions of beer grains solid state fermentation were obtained.
