The rapidly depleting fossil fuel resources and stringent emission norms have given importance to research of alternative fuels, especially in relation to reduction of greenhouse gases and global warming.In the work presented, biodiesel was derived from honge oil, which is non-edible.The oxidation stability of honge oil biodiesel is low due to the
In order keychron m4 to explore the improvement of radar radial velocity data assimilation on the initial and forecast fields of typhoons, this study assimilates the quality-controlled radial velocity data in the case of Typhoon Linfa (2015) using the three-dimensional variational data assimilation system of the weather research and forecasting mod
Introduction.The influence of two ways of organizing scalar product on the convergence rate of the solution in the energy method of boundary states is considered.The method is based on the spaces of internal and boundary states which are conjugated through isomorphism.Both spaces are orthonormalized using one scalar product or another.The desired s
