Verification and Validation in Computational Science and Engineering
Method of grinding elongated, cylindrical workpieces in continuous operation in a grinding machine wherein the workpieces are advanced while they are rotated about their longitudinal axes includes exerting an oscillating grinding pressure transversely to the longitudinal axis of the workpiece, and adjusting the frequency of the oscillations to lie substantially in low-to-medium frequency range, outside the frequency ranges of resonant vibrations of parts of workpiece and of the grinding machine.

Completed Richardson extrapolation
The Richardson extrapolation method, which produces a 4th-order-accurate solution on a subgrid by combining 2nd-order solutions on the fine grid and the subgrid, is ‘completed’ – in the sense that aExpand
