For the congestion problem of persecuting Internet, an algorithm is presented by global terminal sliding mode control and fuzzy inference. Uncertain and time-varying delay factors are also considered into the system. A new global terminal sliding surface is designed. The sliding surface can make the system movement possesses global robustness. Moreover, the sliding mode possesses finite convergence...
Deep-drawn interfacial free (IF) steel is one of the important raw materials in the automotive industry. Due to the complex production processes and numerous influence factors, it is difficult to construct the predicted model between microstructure and yield strength using the quantitative mathematical method. So, it is proposed to use BP neural network to construct the model to describe the relationship...
The catalytic activity of TiO 2 nano-particles, prepared by a sol–gel method, was studied when added in the reaction between SO 2 and CaO. The reaction products were analyzed by infrared spectrophotometry (IR) and specific surface area analysis and the kinetics and mechanisms of the sulfation catalyzed by the addition of TiO 2 are discussed. The results indicate that nano-TiO...
Dialectical materialism is a kind of science about the common rule that nature, society and thoughts of human beings develop, and is the fundamental method for people understand the world and change it. It is urgent for the college education in ideology and politics to use the method to solve some related questions. Dialectical materialism has methodological significance to college education in ideology...
Wafangdian wastewater treatment plant (WTP) employed intermittent cycle extended aeration system (ICEAS), which was the first application in the northeast of China. WTP achieved good performance in the past almost three-year operation with effluent quality of COD 26~52 mg/L (40 mg/L in average), BOD 6~17 mg/L (11 mg/L in average), NH4+-N 0.68~7.79 mg/L (3.87 mg/L in average), TN 11.61~19.44 mg/L...
