Exploring the Dielectric Strength Enhancement of Virgin Coconut Oil as an Alternative Transformer Liquid Insulation through Nanomaterial Additives

Sagir Isyaku^*, Adamu Abubakar Sa’idu, Umar Musa

Virgin coconut oil (VCO) is a biodegradable natural ester whose dielectric strength and thermal performance remain below those of mineral oil. This study enhanced VCO with surface-modified TiO₂, Al₂O₃ and SiO₂ nanoparticles (0.01–0.05% w/v), prepared by magnetic stirring and ultra-sonication and characterized by XRD, SEM/TEM, EDX, FTIR, UV–Vis and ...

REVIEW ON METAHEURISTIC-BASED DECISION TREE INDUCTION

Ismaila Mahmud^*, Abubakar Abdulkarim, Sulaiman Haruna Sulaiman, Umar Musa

Decision tree is one of the well-known machine learning algorithms which remain popular due its simple implementation and ease of understanding. Existing techniques used in inducing decision tree have shown that they suffer data overfitting which leads to producing small size of decision tree model. To address the drawback and improve the performan...
