The ill-posed inverse problem of propagation of long waves in a domain of arbitrary form with the sufficiently smooth boundary on a sphere is consider. Numerical solution is based on finite elements method. Parallel software using MPI is performed. We compared efficiency of two popular implementations of the MPI standard and studied the behavior of our software when using various ways of memory allocation. © 2011 Springer-Verlag Berlin Heidelberg.

This article examines the reasons for the occurrence of anode effects on S-8BM electrolytic cells with selfbaking anodes at the Krasnoyarsk Aluminum Plant. It discusses the possibility of reducing the frequency of anode effects based on data on the manner in which the electrical conductivity of the electrolyte is affected by changes in the content of elemental carbon in the electrolyte before and after cell maintenance. © 2011 Springer Science+Business Media, Inc.

The methods of microscopic and x-ray spectrum analysis are used to study nonmetallic inclusions in ingots and shapes from alloy AD31 and in the initial materials and products of interaction between the melt and the furnace fluxes and lining with the aim to determine the sources of contamination of the melt and effective fluxes for their removal. © 2015 Springer Science + Business Media New York.
