The title compounds were prepared by melting and annealing of stoichiometric mixtures of the elemental components in a high-frequency furnace. They are isotypic with Yb2Ru3Ga10 (P4/mbm, Z = 2). Their lattice constants were determined from X-ray powder data, and their crystal structures were refined from single-crystal X-ray data. Er2Os3Ga10: a = 883.4(1), c = 636.7(1) pm, R = 0.025 for 506 Fo v...

A system for arc steel melting furnace arcs power control with fuzzy corrector is proposed. Digital model of the system was created and numerical simulation under influence of deterministic and random disturbances of arc lengths were conducted. Results of simulations are shown, which prove improvements of dynamic and static indices of arc power regulation. Streszczenie. Praca przedstawia system...
