Improving performance of collaborative question answering systems by using semantic resources
Published 2015“…The question analysis phase in the proposed research attempts to improve the question matching in two steps. In the first step, called Question classification, questions are classified into several coarse grained and fine grained classes based on some rules. …”

Central unstaggered finite volume methods for shallow water equations
Published 2007“…In contrast with the original (NT) central scheme that evolves the numerical solution on an original grid (at even time steps) and on a staggered one (at odd time steps), the method we propose evolves the numerical solution on a single grid and uses a “ghost” staggered grid to avoid the time consuming resolution of the Riemann problems arising at the cell interfaces. …”
