must be profitable. But how profitable and how successful spam campaigns are has not been quantitatively measured. One reason that this has yet to have been studied is that designing a methodology for the inquiry into the strategies and success of spammers has presented a number of knotty problems for researchers. But in a bold move, CNS faculty researchers Geoffrey Voelker and Stefan Savage (p...

Numerical simulation of gas flow in porous media is becoming increasingly attractive due to its importance shale and natural production carbon dioxide sequestration. In this paper, taking molar densities as the primary unknowns rather than pressure fractions, we propose an alternative formulation multicomponent Maxwell–Stefan (MS) model with rock compressibility. Benefiting from definitions sol...

We introduce and discuss the Homotopy perturbation method, the Adomian decomposition method and the variational iteration method for solving the stefan problem with kinetics. Then, we give an example of the stefan problem with  kinetics and solve it by these methods.
