An Accurate Upper Bound Solution for Plane Strain Extrusion through a Wedge-Shaped Die by Sergei Alexandrov, Yusof Mustafa, Yeong-Maw Hwang, Elena Lyamina

“…An upper bound method for the process of plane strain extrusion through a wedge-shaped die is derived. A technique for constructing a kinematically admissible velocity field satisfying the exact asymptotic singular behavior of real velocity fields in the vicinity of maximum friction surfaces (the friction stress at sliding is equal to the shear yield stress on such surfaces) is described. …”

A Second Order Characteristic Method for Approximating Incompressible Miscible Displacement in Porous Media by Tongjun Sun, Keying Ma

“…An approximation scheme is defined for incompressible miscible displacement in porous media. This scheme is constructed by two methods. Under the regularity assumption for the pressure, cubic Hermite finite element method is used for the pressure equation, which ensures the approximation of the velocity smooth enough. …”

Dynamic Behavior Analysis of Stochastic Nonautonomous Logistic Model with Limited Resources and Lévy Jump by Yonggang Ma, Junmei Liu

“…In this paper, we discuss the dynamic behavior of the nonautonomous stochastic logistic model under the influence of limited resources and Lévy jump. Firstly, by constructing the Lyapunov function and using the Itô formula, we prove the persistence and extinction of the solution of the model in the sense of p-moment. …”

An SIR Epidemic Model with Time Delay and General Nonlinear Incidence Rate by Mingming Li, Xianning Liu

“…The disease transmission function and the rate that infected individuals recovered from the infected compartment are assumed to be governed by general functions F(S,I) and G(I), respectively. By constructing Lyapunov functionals and using the Lyapunov-LaSalle invariance principle, the global asymptotic stability of the disease-free equilibrium and the endemic equilibrium is obtained. …”
