An algorithm of wave equation datuming
The article describes the wave equation datuming is the procedure in seismic exploration that used for removing of the influence of Weathering Velosity Zone. It means transform the wave field at free boundary to some level below that Zone. Numerical procedure for solving this problem ...
Decay of a weak gap and wave propagation in a nonlocal environment with a source
A spatially non-local fourth-order wave equation with a source is considered. The results are set out in terms of the heat transfer theory. The temperature derivative of the source function is positive (a technical source) or negative (a source in biological tissue). The wave velocity ...
Oscillations, resonances and waves in a non-local medium with sources
New exact solutions are obtained for a spatially non-local wave equation with sources. The results are set out in the terms of the heat transfer theory. The non-locality of the problem is determined by the value of the fourth spatial derivative. We considered two types of volume energy sources which are alternating ...
