The numerical simulation of gas dispersion is of great importance in various areas of engineering such as optimisation, synthesis of chemical process, petroleum industry and process safety. The OpenFOAM (Open Field Operation and Manipulation) code is a free and open source computational fluid dynamics (CFD) program. The current research is focused on the development and customisation of a computational...
In this paper it is shown that there are strong statistical evidences towards the presence of long memory components in three American macroeconomic time series (Output Gap, M1 Quantity of Money and Real Interest Rates). Moreover, in this paper is presented two Fractionally Integrated Vector Autoregression (FIVAR) models with the fractional difference coefficients estimated using two different procedures...
