A printing moving membrane is studied. The model of the moving membrane with parabolic density is established. Then, the Von-Karman equations expressed by the deflection function and the internal force function of axially moving membrane are derived based on the theory of elasticity. The nonlinear vibration characteristics of the variable density moving membrane under clamped boundary are studied...
This paper proposes a rail defect detection method based on vibration acceleration signals. The vibration signals are generated from the vehicle-track coupling model by inputting different typical rail defect excitations. The empirical mode decomposition method is used to decompose the signal. Intrinsic mode functions that have a big cross-correlation coefficient with the original signal are selected,...
In this paper, we proposed a new data fusion method to infer gene regulatory networks based on differential equations model. After testing on several simulation and real data sets, and comparing with three other kinds of single fusion methods, the results show that our method is effective and better than other 3 fusion methods in inferring networks.
