Weathering of wood--plastic composites (WPCs) leads to discoloration and cracks, which greatly limits their outdoor application.In Power Supply Harness this study, light stabilizers (including UV-327, HS-944 and nano-SiO2) were added to the shell of a co-extruded high-density polyethylene-based WPC to improve its anti-ultraviolet (UV) ageing proper
The developed technologies for creating the three-dimensional shape for the formation of feminine personal protective armor proved to be applicable in the case of high-performance protective triaxial fabric, made of polyester, Vectran, and Kevlar.The suggested method combines cyclic loading and deep forming under heat.Cup shape geometry was analyze
In this paper, game-theoretic optimization by particle swarm optimization (PSO) is used to determine the Nash equilibrium value, in order to resolve the confusion in choosing appropriate bidders in multi-round procurement.To this end, we Stroller Toys introduce an approach that proposes (i) a game-theoretic model of the multi-round procurement prob
