Clearing directed subgraphs by mobile agents
PublicationWe study several problems of clearing subgraphs by mobile agents in digraphs. The agents can move only along directed walks of a digraph and, depending on the variant, their initial positions may be pre-specified. In general, for a given subset S of vertices of a digraph D and a positive integer k, the objective is to determine whether there is a subgraph H=(V,A) of D such that (a) S is a subset of V, (b) H is the union of k directed...

On description of periodic magnetosonic perturbations in a quasi-isentropic plasma with mechanical and thermal losses and electrical resistivity
PublicationMagnetosonic periodic perturbations in a uniform and infinite plasma model are considered. Damping due to compressional viscosity, electrical resistivity, and thermal conduction are taken into account, as well as some heating–cooling function, which may destroy the isentropicity of wave perturbations. The wave vector forms arbitrary angle h with the equilibrium straight magnetic field, and all perturbations are functions...

On the Nonlinear Effects of Magnetoacoustic Perturbations in Optically Thin Quasi-Isentropic Plasmas
PublicationNonlinear effects of planar magnetosound perturbations in a plasma are discussed. Plasma is non-adiabatic due to optically thin radiation and external heating. For these reasons, thermal instability of a plasma may appear which makes it acoustically active. The plasma is assumed to be initially homogeneous ideal gas with infinite electrical conductivity permeated by a straight magnetic field which is orthogonal to the trajectories...

Usługi publiczne jako czynnik miastotwórczy i wyznacznik rangi miasta w sieci osadniczej na przykładzie małych miast Polski północnej
PublicationMałe miasta, podobnie jak większe, pełnią różne funkcje egzogeniczne wyspecjalizowane, a także funkcje standardowe, zwane też centralnymi (Domański 1972), polegające na obsłudze bliskiego, a nieraz też dalszego otoczenia. Są z tego powodu koncentracjami miejsc pracy dla mieszkańców swoich i otoczenia. Jedną z funkcji miastotwórczych są usługi. Ich udział w strukturze zatrudnienia, jak wykazywał Fourastier (Goryński 1966) rośnie...
