Transport of pollution is strongly influenced by groundwater flow. All numerical models of transport equation must be based on the groundwater flow models. The most of them suffer from numerical diffusion and/or oscillations of solution. Both phenome

This paper deals with a new modification of the local boundary knots method (LBKM), which will allow the irregular node distribution and the arbitrary shape of the solution domain. Unlike previous localizations, it has no requirements on the number o

The COMPASS Upgrade tokamak (B = 5 T, IP = 2 MA, R = 0.894 m, a = 0.27 m) requires strengthening of the existing foundations due to larger electro-magnetic (EM) loads occurring during plasma disruption events. The focus is given to the VDE as they cr

Mathematical models are the effective tool to solve different tasks predicting pollutant movement. The finite difference method is the oldest, but still remains widely used in hydrogeological practice. However, this method is not very useful to const
