Sep 2 comment Bound on the mean value of function involving Hilbert transform Also, why do you care about this problem? Jul 3 awarded Nice Answer May 16 comment Test for normability of a metric on a Banach space Sorry, what do you mean by normable? May 15 comment Are my results realistic or is there an error somewhere? It is physically meaningful, and a known environmental issue. It is the reason why the US Navy and geophysical exploration companies have been accused of making marine mammals going deaf. This behavior cause the wave to propagate essentially in 2D and reduces the decay by an order. So sounds are loud in the channel miles away. May 15 comment Are my results realistic or is there an error somewhere? This sort of behaviour is common for sound waves under water. Read about the SOFAR channel:en.wikipedia.org/wiki/SOFAR_channel May 13 comment Tools for learning Finite Element Method Check out mooseframework.org for how to do some finite elements; you won't have to learn to code. May 13 comment Tools for learning Finite Element Method Spectral methods do not converge quickly in the presence of discontinuities. In Mech E, there generally are.
