We construct new HLL-type moving-water equilibria preserving upwind schemes for the one-dimensional Saint-Venant system of shallow water equations with nonflat
Vibrations of a beam can be described as an Euler-Bernoulli beam,or as a Rayleigh beam or as a Timoshenko beam.In this paper,we establish the existence of perio
In this paper,a reconstruction problem of the spatial dependent acoustic source from multiple frequency data is discussed.Suppose that the source function is su
