The paper presents asymptotic models and numerical illustrations of periodic systems which possess band gaps and support standing waves at low frequencies. The structures considered here include periodic systems of defects (cracks or resonators of different types). Tuning mechanisms are described to control the position of band gaps in dispersion diagrams.

    The graph of a function f is subjected to non-homogeneous dilatations around the point (χ0; f(χ0)), related to the Taylor's expansion of f at χ0. Some questions about convergence are considered. In particular the dilated images of the graph are proved to behave nicely with respect to...

    The problem of finding parameters of asymptotic relations for the probability of operation of a graph with unreliable ribs is solved. These parameters are expressed through minimax functions of lengths of ribs. To compute them, an economical modification of the Floyd algorithm is constructed.

    In this paper, we give an estimate on the growth of the scaling sequence of the Pascal adic transformation with respect to the sup-metric. We construct a special class of α-names of positive cumulative measure. The linear growth of its cardinality implies the logarithmic growth of the scaling...
