By using the interaction of particles, such as the physical principle of the same attract each other and the different repulse each other, a new model of Lattic
The Delta-perturbation expansion method, a kind of new perturbation technique depending upon an artificial parameter Delta was studied. The study reveals that t
Three dimensional steady flowfield generated by transverse sonic injection into a supersonic flow was simulated by solving the Favre-averaged Navier-Stokes equa
The combined hybrid finite element method is of an intrinsic mechanism of enhancing coarse-mesh-accuracy of lower order displacement schemes. It was confirmed t
By using the variational Liapunov method, stability properties in terms of two measures for delay differential equations are discussed. In the case that the unp
A boundary value problems f or functional differenatial equations, with nonlinear boundary condition, is studied by the theorem of differential inequality. Usin
