    Abstract: The present paper is devoted to the study a dynamic problem describing a frictionless contact between a thermo- elasto-viscoplastic body and an adhesive foundation. The constitutive law includes a temperature effect described by the first order evolution equation. The contact is modelled with a normal compliance condition involving adhesion effect ... Show More

    Abstract: The number of spanning trees in graphs (networks) is a crucial invariant, and it is also an important measure of the reliability of a network. Spanning trees are special subgraphs of a graph that have several important properties. First, T must span G, which means it must contain every vertex in graph G, if T is a spanning tree of graph G. T needs ... Show More
