Using covering graph techniques, a structural result about connected cubic simple graphs admitting an edge-transitive solvable group of automorphisms is proved. This implies, among other, that every such graph can be obtained from either the 3-dipole Dip3 or the complete graph K4, by a sequence of elementary-abelian covers. Another consequence of the main structural result is that the action of...

Let D be a non-trivial simple t-design. For 1 ≤ s ≤ t, we generalize the concept of the incidence graph of D and construct a new bipartite regular graph Γ. We obtain that the edge-transitivity of the graph Γ is equivalent to the s-flag-transitivity of the design D. We then, for s = 2, classify the semisymmetric graphs among the graphs Γ constructed from biplanes and triplanes. Finally, we study...

despite recent advances in video inpainting techniques, reconstructing large missing regions of a moving subject while its scale changes remains an elusive goal. in this paper, we have introduced a scale-change invariant method for large missing regions to tackle this problem. using this framework, first the moving foreground is separated from the background and its scale is equalized. then, a ...
