In quantitative EDXRF analysis of ancient metallic objects two main difficulties arise : i) how to Γnd out the correction factors for the irregular shape or relief e β ects and ii) how to measure the true composition of the bulk metal under the surface patina. In the case of coins, taken as a typical
## Abstract Fractionalβstep methods solve the unsteady NavierβStokes equations in a segregated manner, and can be implemented with only a single solution of the momentum/pressure equations being obtained at each time step, or with the momentum/pressure system being iterated until a convergence crit
