<正>By direct numerical simulation, a supersonic boundary layer was studied to see whether the mechanism for the generation of sub-harmonic waves, similar to th
<正>The dynamical behaviour of a parametrically excited Duffing-van der Pol oscillator under linear-plus-nonlinear state feedback control with a time delay is c
<正>Support vector machine (SVM) was introduced to analyze the reliability of the implicit performance function, which is difficult to implement by the classica
The homoclinic solutions problem of the Davey- Stewartson (DS) Equations were studied. By using the Hirota's bilinear method, the homoclinic orbits of the D
For the orthotropic piezoelectric plane problem, a series of piezoelectric beams is solved and the corresponding exact solutions are obtained with the trial-and
