In this paper, we prove that all but one of the components transfer digraph D? m needed for enumeration 2-factors in rectangular, thick cylinder and Moebius strip grid graphs fixed width (m ? N) are bipartite digraphs their orders could be expressed term binomial coefficients. addition, set vertices each component consists binary m-words which difference numbers zeros odd even positions is cons...

In various fields of engineering, such structural elements are widely used that, from the point view their strength calculation, can be referred to thin shells (tanks, reservoirs, cylinders, etc.). When calculating thin-walled shells, a number hypotheses adopted simplify solution problem. The problem is most simply solved within framework momentless theory according which only force normal sect...

The rate at which fluid drains from a collapsing channel or crack depends on the interaction between the elastic properties of the solid and the fluid flow. The same interaction controls the rate at which a pressurized fluid can flow into a crack. In this paper, we present an analysis for the interaction between the viscous flow and the elastic field associated with an expanding or collapsing f...
