Purely hydrodynamic numerical experiments into the evolution of astrophysical discs typically include some sort of viscosity in order to cause accretion. In this paper, we demonstrate an alternative method of implementing viscous forces, with extremely good angular momentum conservation properties. The method is based on altering the cell fluxes, rather than incorporating a viscous force. We te...

Is it possible to achieve non-repudiation during electronic contractsigning? How can this be achieved in an e-mail based environment? These are the questions we will try to answer. The process of getting these answers will involve a short introduction to some of the available contract-signing standards and an analysis of how well the given standard would work in a e-mail environment. Additional...
