This paper describes an approach to the use of neural networks for improving the scientific paper classification performance. On the basis of the initial classification results obtained from the content-based naive Bayes method, this approach uses neural networks to model the citation link structures of the scientific papers for refining the class labels of(More)
Welding is a complex process including of physics, conducting heat, metallurgy, mechanics. when producing residual stress, crack, air holes and so on in the parts, it will reduce welding strength and welding quality. Though there are many methods to relif residual stress, it is a difficult problem about how to improve it. We use welding with trailing(More)
In order to eliminate welding stress and improve the quality of welding.The technology of constant frequency pulse width modulation (PWM) is applied in the design of control circuit of welding with trailing peening.AT89C52 is the core of the circuit.This systemby the BCD dial provide reference voltage to the single-chip,by controlling the device of trailing(More)
