In this paper, the Dirichlet boundary value problems of the nonlinear beam equation u_(tt) + ?_u~2 + αu + ∈Φ(t)(u + u~3) = 0, α > 0 in the dimension one is
We introduce the triple crossing number,a variation of the crossing number,of a graph,which is the minimal number of crossing points in all drawings of the grap
In this paper, we combine a split least-squares procedure with the method of characteristics to treat convection-dominated parabolic integro-differential equati
Recurrent event gap times data frequently arise in biomedical studies and often more than one type of event is of interest. To evaluate the effects of covariate
