In order to deal with large problems, a pair of trust region subproblems in horizontal and vertical subspaces is used to replace the general full trust region subproblem.
For indicating the effect of the spatial correlation of input motions, the horizontal uniform inputs, as well as the horizontal and vertical uniform input are carried out for the seismic response analysis of the site.
Based on horizontal and vertical ion drift in planetary waves, a possibility of plasma density increases by a factor of 10-20 in comparison with the background concentration is demonstrated.
