We discuss the maximum size of uniform intersecting families with covering number at least {. Among others, we construct a large k-uniform intersecting family with covering number k, which provides a counterexample to a conjecture of Lova sz. The construction for odd k can be visualized on an annulu

A boundary element scheme is proposed for evaluation of the four-pole parameters of ducts and mufflers in the presence of a low Mach number non-uniform flow. A transformation of variable is used, such that the governing sound propagation equation reduces to the Helmholtz equation in the transformed
