In this paper, modeling a weakly nonlinear system whose nonlinearity is up to the second order is studied. During this task a second order Hammerstein series model is used because it can lead to a trade-off between computational cost and generalization ability. To extract such model form measured input-output...

Conventional Volterra series model is hardly applied to engineering practice due to its parametric complexity and estimation difficulty. To solve this problem, nonlinear system identification using reduced complexity Volterra models is proposed. Since the nonlinear components often play a secondary role...

The measuring of water content in oil products affects the reliability and safety of the steel high speed wire rod production. Based on the existing capacitance sensor online water content detector, the neural network algorithm is used to deal with the data fusion processing with the 3D temperature experimental...

Fine suspended matter such as sediment, organic matter and inorganic matter can absorb a large amount of bacteria, viruses and other harmful substances, which is a threat to human health, and water turbidity is one of the important indicators of water quality monitoring. The ratio method of the photoelectric...

Research is carried out on the kinematics of a kind of small biped robot. The robot mechanical structure with six degrees of freedom is designed according to the bionic human body and the kinematical model of the robot is constructed through the transformation Matrix. In the inverse kinematical analysis,...

Research from the angle of energy is one of the important way to explore the cause of coal and gas outburst for grasping the law of coal and gas outburst. In order to study energy dissipation law in the process of coal and gas outburst. Build the relationship between strain and stress of coal and rock...

C4.5 algorithm is one of the ten classic algorithms of data mining, it is a series of algorithms used in machine learning and data mining. This paper mainly studies the application of C4.5 algorithm to the analysis of performance data, to dig out the hidden relationship between various factors and test...

Traditional examination by the teacher to choose, group, organization, after the examination, and then by the examination papers to correct, determine the results. Therefore, many factors, such as the standardization degree, the difficulty degree and the rationality of the evaluation, are more easily...
