Calculation of the friction factor of turbulent oscillatory fluid flow is a significant issue in accessing bed shear stress and sediment entrainment in coastal areas. A fast, robust calculation is ...

The localized energy estimate for the wave equation is known to be a fairly robust measure of dispersion. Recent analogs on the (1 + 3)-dimensional Schwarzschild space-time have played a key role in a ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...
