Prediction of uniaxial compressive strength of limestone from ball mill grinding characteristics using supervised machine learning techniques.

Uniaxial Compressive Strength (UCS) is a fundamental parameter in rock engineering, governing the stability of foundations, slopes, and underground structures. Traditional UCS determination relies on laboratory tests, but these face challenges such as high-quality core sampling, sample preparation difficulties, high costs, and time constraints. These limitations have driven the adoption of indirect approaches for UCS prediction.

Sustainable RCCI engine operation with an ANN based novel tri-fuel approach.

This research delves into a novel tri-fuel RCCI engine strategy that uses diesel as the base fuel, biodiesel from Andropogon narudus, and hydrogen as a reactivity promoter to enhance combustion efficiency and enhance environmental sustainability. The tested blends, BD80H20 and BD70H30, showed a 3-5% improvement in Brake Thermal Efficiency (BTE) compared to conventional diesel at full load operation. Hydrogen-rich blends recorded a 5-8% brake-specific fuel economy improvement over diesel and B20 at both 75% and 100% engine loads.

Experimental investigation of influence of age hardening temperature and cooling medium on tribological behaviour of aluminium/tungsten carbide metal matrix composite.

This work investigates the hardness and wear resistance of an Aluminum/Tungsten carbide metal matrix composite in relation to its age-hardening temperature. The composite was fabricated by stir-casting technique, and samples were cooled in a furnace, water, and atmosphere after being aged for two hours at 0 °C, 250 °C, and 450 °C. The results showed that the composite aged at 250 °C under furnace cooling achieved a 50.

Detecting industrial motor faults with current signatures.

A major player in industry is the induction motor. The constant motion and mechanical nature of motors causes much wear and tear, creating a need for frequent maintenance such as changing contact brushes. Unmannered and infrequent monitoring of motors, as is common in the industry, can lead to overexertion and cause major faults.
