We introduce a preconditioning technique based on Domain Decomposition and the Fast Diagonalization Method that can be applied to tensor product based discretizations of the steady convection-diffusion and the linearized Navier-Stokes equations. The method is based on iterative substructuring where fast diagonalization is used to efficiently eliminate the(More)
— News sentiment has been empirically observed to have impact on financial market returns. In this study, we investigate firm-specific news from the Thomson Reuters News Analytics data from 2003 to 2014 and propose an optimal trading strategy based on a sentiment shock score and a sentiment trend score which measure extreme positive and negative sentiment(More)
Application results are described of a new parallel Navier-Stokes solver developed by Nektonics Inc. for NASA. The 3D unsteady code is based on the spectral-element method which combines the geometric exibility of nite-element methods and the high accuracy of spectral methods. The dis-cretization methodology, parallelization technique and performance(More)
