Comprehensive Analysis of Stability of Coal Seam Composite Roof Based on Analytic Hierarchy Process

open access: yesAdvances in Civil Engineering, 2019
The composite roof structure of coal roadway is complex, and its stability is related to lithology of strata, strata thickness, number of strata, strata location, and interlayer cohesive force. Based on a simplified model of the composite roof structure,

On compositions of numbers and graphs

open access: yes, 2007
The main purpose of this note is to pose a couple of problems which are easily formulated thought some seem to be not yet solved. These problems are of general interest for discrete mathematics including a new twig of a bough of theory of graphs i.e. a given graph compositions.
