Underground Fault Detection and Classification: An Explainable, SCADA-Ready Pipeline with Adaptive DWT and Compact CNN-Transformer

Kabiru Ibrahim Dahiru^*, Abubakar Ahmed, Sulaiman Haruna Sulaiman, Yusuf Idris, Aliyu Lawan Musa, Ibrahim Mahdi

Underground faults are difficult to detect and classify reliably because transient signatures are short-lived, dispersive, and often masked by operating noise. Deployment in supervisory control and data acquisition (SCADA) environments demands deterministic, sub-millisecond latency and transparent d...

Advancements in Raw Material Availability, Development Strategies, and Industrial Prospects for Zinc-Carbon Dry Cell Production In Nigeria and Uganda

Excellence Favor, Abubakar Abdulkarim^*, Yinusa Ademola Adediran

Nigeria could boast of at least six functioning dry cell manufacturing industries. Unfortunately, today, these industries have gone into oblivion with only one trying, epileptically, to survive. One major factor responsible for this is the higher cost of production than the sales price of imported r...

Development of Optimal Electricity Management Systems to Minimize Resources and Losses using Particle Swarm Optimization Techniques: A Case Study for UDUS

A. U,Lawan^*

Hybrid energy systems (HESs), have played an important role as clean and efficient source of electricity generation. HESs are often formulated as an optimization problem which is solved mostly using metaheuristics techniques. The conventional objective function is based on levelized cost of energy (...
