When it comes reading forecast graphs, swell period is definitely the magic number. Indeed, for a forecaster, explaining the implications of swell period is a bit like the birds and the bees – of ...

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, ...

The wave equation is a very important formula that is often used to help us describe waves in more detail. It should be noted that some particular waves have their own specific speeds. The speed of ...

It was shown in two earlier papers that, if u(x, t) = u(x1, x2, x3, t) satisfies the wave equation in the exterior of some fixed sphere r = a and vanishes for t ⩽ r, then ru(rξ, r + τ) ∼ f(ξ, τ) as r ...

Pressure waves propagating through bubble-containing liquids in tubes experience considerable attenuation. Researchers have now derived an equation describing this phenomenon, demonstrating that ...
