In this paper,we study a band constrained nonnegative matrix factorization (band NMF) problem:for a given nonnegative matrix Y,decompose it as Y ≈ AX with A a
In this paper,the MMC-TDGL equation,a stochastic Cahn-Hilliard equation with a variable interfacial parameter,is solved numerically by using a convex splitting
The focus of this special issue is optimization methods for problems whose solutions have simple structures.These structures include sparsity (the solution has
In this paper,we present a new stabilized finite element method for transient Navier-Stokes equations with high Reynolds number based on the projection of the v
The Entropy-Ultra-Bee scheme was developed for the linear advection equation and extended to the Euler system of gas dynamics in [13].It was expected that the t
