This work discusses the stratigraphic and structural patterns of the baryte fields in Alifokpa-Osina -Gabu barite field in Yala Local Government Area of Cross-River State of Nigeria, with a focus to advocating adequate mining techniques. The stratigraphic sequ…

In order to protect animal welfare, increase production, and lower the frequency of disease outbreaks, the growing poultry industry particularly in battery cage systems requires advanced monitoring technologies. This study presents the development of a machine…

This work discusses the compositional features and economic potentials of the barites from Alifokpa-Gabu-Osina and environs in the Lower Benue Trough of Nigeria, with a focus to unravelling the economic potentials of the deposit. Results of the geochemical ana…

This study presents an Internet of Things (IoT)-driven management system for poultry battery cages, leveraging cloud computing and computer vision technologies to improve the efficiency, productivity, and monitoring capabilities in poultry farming business. Co…

Monitoring of transformer substations in the Nigerian power distribution network is largely done by manned intervention. Outages due to possible fault conditions are only taken account of when reported by customers or discovered through patrol visits. This res…

The greatest challenge today for any event or academic management is efficient attendance tracking. A major limitation of current systems is their trade-off. Manual methods often lead to mistakes and allow for proxy attendance. On the other hand, automated t…

The Nigerian national grid (NNG) is plagued by significant transmission constraints, resulting in inefficient electricity delivery across the country. Inadequate transmission and distribution facilities are primary contributors to Nigeria's epileptic power s…

The study focused on the evaluation of effects of steel slag and fly ash on the properties of asphalt concrete. Steel slag and fly ash with conventional materials such as aggregate, fillers and bitumen were used in this study. Experimental test to ascertain …

In the era of unprecedented disruptions, resilient supply chain engineering has emerged as a critical domain for ensuring sustainability, adaptability, and operational continuity. This research explores the integration of resilience strategies and sustainabi…

This study examines the factors influencing intercity mode choice behavior among travelers in Akure, Nigeria, with the aim of identifying key determinants, developing predictive models, and providing policy recommendations for improved transportation systems…

This study presents an Internet of Things (IoT)-based solution for monitoring and measuring various electrical parameters in a three-phase power system. The system is intended to address the problem of lack of real-time remote monitoring and processing of en…

The different uses of DC motors (for both domestic and industrial) make changing the speed from one level to another very important to suit the required speed needed for any particular purpose. The control of this machine can be done using AC/DC power conver…

Moist cellulose acetate agglomerates were investigated for their compressive strength and some physical factors interactions using statistical methodology. These agglomerates were prepared in a rotating balling disc using different sieve sizes of cellulose a…

This paper presents 24 to 28 GHz MMIC (monolithic microwave integrated circuit) class-J GaAs pHEMT power amplifier with non-Foster matching for 5G communication systems. The power amplifier (PA) was designed with Keysight Advanced Design System (ADS) Softwar…

This paper conducts a detailed technical analysis of the integration of solar and wind energy into Nigeria's 330 kV power grid. Despite extensive power sector reforms, Nigeria's energy demand continues to surpass supply, with heavy reliance on fossil fuels l…

Transmission and distribution lines are protected against fault in power network using protection methods and distance relays. This work focused on enhancing the speed of isolating defective circuits from the network by employing a microprocessor to minimize…

This paper presents an analysis of the effective capacitance of one-port S-band gallium nitride high electron mobility transistor (GaN HEMT) non-Foster negative-reactance circuit. The analysis was carried out at Sband frequency ranges of 4.08 GHz to 4.11 GHz …

Rogowski coil is considered an electrical device used for the measurement of Alternating Current (AC) or high-speed current pulses from other devices. It has gone through many stages of development towards improving its performance and applications. It has b…

This work aimed at providing a qualitative analysis of technical losses in transmission lines using Nigerian 330 kV lines as a case study. The specific objectives of this study include mathematical modeling of the Nigeria transmission network, incorporating …
