The flow movement state at the junctions of open channels is very complex, and one-dimensional high-precision numerical simulation still faces significant challenges.This paper established a mathematical model of hydrodynamics at the junctions of open channels, which was completely decoupled from branch channels and junctions.In terms of the juncti

Multicriteria decision making (MCDM) is a field that helps decision makers evaluate alternatives based on multiple criteria and encompasses Pin Switch scoring, distance-based, pairwise comparison, and outranking methods.Recent developments have aimed to solve specific problems and overcoming the limitations of previous methods.This paper proposes a

Monitoring the condition of building structures based on composite materials in aggressive environments shows that the deterioration of basic properties occurs under the influence of various factors such as temperature and humidity changes, in addition to changes in the chemical composition of air environment.In addition, the composite materials du
