Intelligent decision analytics with recursive learning for competitive sports management

The increasing availability of sports performance data has created new opportunities for data-supported decision-making in competitive sports management. However, redundant and strongly correlated performance indicators can increase analytical complexity and distort the influence...

Coupling Effects of Texture Density and Counterpart Material Hardness on the Dry Sliding Friction of TC4 Titanium Alloy

Circular microtextures with area densities of 5%, 10%, 15%, and 20% were fabricated on TC4 titanium alloy surfaces and tested under dry sliding conditions against four counterpart balls of varying hardness (Brass, SUS304, AISI 52100, and K20). Through coefficient of friction (COF...
