We present a systematic study of novel entropy stable approximations for a variety of nonlinear conservation laws, from the scalar Burgers equation to one dimensional Navier-Stokes and two dimensional shallow water equations. To this end, we construct a new family of second-order entropy stable difference schemes which retain the precise entropy decay of(More)
This paper analyses the national competitive ability of China based on world and Chinese 500 data. In the first part, this paper presents the compendium of basic facts of trends of Global 500 and Chinese 500. Firm scales not only increased expeditiously in the new millennium but also with an obvious escalating of high-tech industries. In the second part,(More)
