OPTIMIZATION OF FRICTION AND ELECTRICAL RESISTANCE PERFORMANCE IN GRAPHITE-COPPER ELECTRICAL CONTACTS USING TAGUCHI-BASED GREY RELATIONAL ANALYSIS

This study aims to investigate how the load, the intensity, and the polarity of electric current influence the frictional behavior and electrical resistance between a graphite pin loaded against a rotating copper disc.A pin-on-cylinder tribometer was utilized to achieve this.A gray relational grade obtained from gray relational analysis was employe

Recently, reconfigurable intelligent surfaces (RISs) aided millimeter wave (mmWave) and terahertz (THz) communication systems have attracted interest as enablers for 5G and beyond networks.Although the static blockers’ impact can be eliminated by the optimal deployment of RISs, the effect of dynamic and self-blockage can only be reduced.Firs
