#### 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 ...
