inverse problem

In the paper the implementation of energy wave field analysis approach for developed informational model of the geological medium is considered. The solutions of seismic inverse problem are presented, which involves geophysical parameters obtaining of geological medium with the use of field seismic data. In order to obtain geological and geophysical environmental parameters the number of wave field transformations are being carried out, conventionally divided into primary and final part (interpretation).

The paper establishes existence and unique conditions for an inverse problem with an unknown source.  The unknown source is a polynomial for а spatial variable with unknown coefficients depending on time.

A modeling problem of the process of liquid multi component decontamination by a spatial filter is considered, it takes into account the reverse influence of decisive factors (contamination concentrations of liquid and sediment) on characteristics (coefficient of porosity, diffusion) of the medium and gives us the possibility to determine small mass transfer coefficient under the conditions of prevailing of convective constituents over diffusive ones.

Purpose. The aim of the research is to develop a methodology for determining local earthquake mechanisms which are registered by a limited number of stations, using real records. Methodology. Methods of the inverse problem solving for determining earthquake parameters are based on the results obtained by direct problem of seismic wave propagation in an anisotropic media using the method of Thomson-Haskell.
