In order to improve the fine MORALE PATCH structure inversion ability of igneous rocks for the exploration of underlying strata, based on particle swarm optimization (PSO), we have developed a method for seismic wave impedance inversion.Through numerical simulation, we tested the effects of different algorithm parameters and different model paramet
The ground ice content in cold environments influences the permafrost thermal regime and the thaw trajectories in a warming climate, especially for soils containing excess ice.Despite their importance, the amount and distribution of ground ice are often unknown due to lacking field observations.Hence, modeling the thawing of ice-rich permafrost soi
Various forms of integral representations of the electromagnetic field are considered.It is shown that the use of analytically developed integral representations of the electromagnetic field instead of the vector potential method makes it possible to significantly simplify the formulation of the internal and external electrodynamic problem for spec
