The increasing demand for environmentally sustainable and cost-effective landfill liner materials has created interest in the utilization of agricultural waste products as engineering materials. This study investigated the suitability of compacted bentonite ad…
Dredging is widely used to restore channel capacity, but its contribution to climate-resilient flood-risk reduction depends on whether sediment-induced loss of conveyance is a principal flood mechanism. This critical narrative review synthesizes evidence on cl…
This empirical research investigated the contributory interactions among highway geometric design parameters, operational traffic characteristics, and environmental factors on heavy freight vehicle crash severity along critical Nigerian transport corridors. Th…
Environmental pollution constrains sustainable development in developing economies, particularly in Sub-Saharan Africa, where rapid urbanization, industrialization, population growth, and weak institutional capacity strain environmental resources. This study a…
This research focuses on modelling and optimization of production of aluminium 360 alloy for six process parameters used in irrigation pipe couplings. Aluminium 360 alloy was selected for its favourable combination of corrosion resistance, pressure tightness a…
Switch mode power supply (SMPS) system has prominently featured in many power system applications. It is a critical component of electric vehicle (EV), providing reliable and efficient voltage link to drive electric motor. In direct current to direct current (…
The selection of appropriate coarse aggregate characteristics is essential for producing concrete with adequate strength for structural applications. This study investigated the strength characteristics of concrete produced with crushed granite of varying part…
Urban drainage systems in growing cities tend to experience capacity deficiencies and intensified runoff in the face of a changing climate. The resilience of urban drainage corridors in Asaba, Delta State, Nigeria, was investigated through scenario-based hydro…
This paper presents a 900 MHz to 1.5 GHz Single-ended CMOS Mixer for wireless communications systems. The Mixer was designed with Keysight Advanced Design System (ADS) Software based on BSIM_3 model nMOS and pMOS field effect transistors biased with drain supp…
The growing complexity of medical devices in healthcare facilities requires effective hazard assessment methods to improve patient safety, equipment reliability, and healthcare delivery. This study developed a Fuzzy Logic-Based Hazard Assessment of Medical Dev…
The rapid growth of wireless systems has increased spectrum demand, making radio resources increasingly scarce. Cognitive Radio (CR) provides a solution by enabling secondary users (SUs) to share spectrum with licensed primary users (PUs) while limiting harmfu…
Rapid consumption of fossil fuels coupled with rising environmental deterioration caused by high CO2 emissions has increased the search for clean and renewable energy sources. Vegetable oils are a main possible alternative to fossil fuel. This present work foc…
Legumes are inexpensive sources of protein, vitamins, fiber, complex carbohydrates and essential minerals, and occupy a special place in human diet, particularly in developing countries. However, their nutritional quality is adversely affected by the presence …
Modern power systems are increasingly exposed to more changing loads and nonlinear operating conditions, which can affect the performance of conventional power factor correction systems. This study presents an enhancement of an adaptive power factor correction…
Fire incidents remain a critical safety challenge in residential, industrial, and commercial environments due to delayed detection and limited immediate response capabilities of conventional systems. This study presents the design and implementation of a smart…
Small tropical streams used for community water supply experience simultaneous dilution, sediment mobilisation and oxygen-balance responses during seasonal transitions. This study quantified dry- and wet-season hydrodynamic and physicochemical variation along …
Faults in three-phase power transmission systems threaten system stability, equipment integrity, and power supply reliability. This study presents an integrated framework for fault detection, localization, and clearing using time-domain voltage and current sig…
This paper presents a protection methodology for distributed generation (DG) with respect to transient instability, using the Enugu distribution network as a case study. A detailed ETAP model of the network was developed, incorporating an integrated microgrid …
