The teaching of analog electronics often suffers from limited hands-on exposure and inadequate instructional tools, which can hinder students’ understanding of fundamental operational amplifier concepts. The design, implementation and performance evaluation of…
Multicarrier communication systems, especially Orthogonal Frequency Division Multiplexing (OFDM), face challenges when it comes to performance, particularly due to high Peak-to-Average Power Ratio (PAPR). This issue can push power amplifiers into nonlinear ter…
The type and quality of fine aggregates significantly affect the strength and durability of concrete. Although river sand has been the preferred choice due to its smooth texture and consistent grading, its dwindling availability and associated environmental is…
Subgrade soil properties critically influence the performance of flexible pavements. This study evaluates subgrade variability and its implications for pavement durability in Nigeria, using soil samples collected at depths of 3 m, 6 m, and 9 m from Akazi sand …
This study investigates the enhancement of frequency stability in an inverter-dominated photovoltaic (PV) microgrid through the implementation of a Virtual Synchronous Generator (VSG)-based virtual inertia control strategy. The increasing penetration of invert…
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…
Road infrastructure drives economic development by facilitating trade, mobility, and regional integration. In Nigeria, poor road networks and traffic inefficiencies limit productivity and growth. This study examines the economic impact of the Nnewi-Okija Road …
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 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…
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…
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…
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…
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…
