In recent times, noise has been recognized as a major source of pollution in many urban and semi-urban settlements. This study identified the various sources of noise, compared noise levels in various parts of the study area with recommended standards and determined the geo-physical characteristic of noise generated in Zaria metropolis. A noise met... Continue Reading
The use of Static Random Access Memory (SRAM)-based Field Programmable Gate Array (FPGA) in critical applications has been considered a solution in space and avionics domain due to its flexibility in achieving multiple requirements such as re-programmability and good performance. However, SRAM-based FPGAs are susceptible to radiation induced Single... Continue Reading
With the ever-growing energy demand over the globe, fluidised bed combustion (FBC) technology is continuously gaining importance due to its ability to burn different low-grade coals and biomass as source of fuel. This study presents a waste-to-energy process by incineration of corncob as an agricultural waste in a fluidised bed boiler for thermal e... Continue Reading
This research work was carried out to investigate the effects and suitability of Cassava starch as an admixture in cement paste and concrete. A standard consistency test was carried out on the cement paste with concentrations of the cassava starch at 0%, 0.5%, 1%, 2%, 3%, 4% and 5% by weight of the cement used in the paste. A prescribed concrete mi... Continue Reading

This research was conducted to produce asbestosfree automobile disk brake pads using eco-friendly; Periwinkle and Fan palm shells materials. The use of asbestos fiber is being avoided due to its carcinogenic nature that might cause health risks. A new brake pad was produced using agro waste materials (periwinkle shell and fan palmshells)with thermo... Continue Reading
The control of voltage level has been identified as one of the most important operational needs for efficient and reliable operation of power system equipment. Due to the fact that both the utility and customer equipment are designed to operate at certain voltage ratings. Prolonged operation of the equipment at voltages outside the allowable range ...

Undoped and copper doped goethite catalysts weresynthesized and applied in Fenton depuration of Kaduna refinery wastewater. The percentage of copper in the doped catalysts are 0.2 wt% copper in Cu-doped (A), 1.6 wt% copper in Cu-doped (B) and 3.3 wt% copper in Cu-doped (C), respectively. Characterization of the catalysts were done using X-ray Diffr... Continue Reading
Research attention has been focussed on the reduction of image data size (major problem) for its efficient compression, storage, and transmission. In this work, the developed brightness enhancement model was used to enhance the Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT), Lifting Wavelet Transform (LWT), and Firefly Optimizati...

In this work, the properties of baobab/sisal fibre reinforced low density polyethylene hybrid composites were studied. The effect of fibre loading and fibre treatment with varying sodium hydroxide (NaOH)concentration on the composite properties was investigated. The developed composites were characterized for tensile strength, modulus of elasticity... Continue Reading
The research titled Development of Eucalpytus tereticornis composite for chromium (VI) and lead (II) ions adsorption from simulated wastewater was aimed to establish the efficacy of Eucalpytus tereticornis composite as an adsorbent applied in the adsorption of Cr6+ and Pb2+ ions from simulated solution of respective ions. The adsorbent was pretreat... Continue Reading
This research presents effect of harmonic generated by variable frequency drives (VFD).In the past, electrical power system equipment and devices were designed to produce nearly sinusoidal voltage and current waveforms. However, nowadays, with much interest and wide spreads of power electronics equipment, for industrials, commercials and residentia... Continue Reading
In recent years there has been an increased awareness to conserve energy through efficient use of fuels, energy saving devices and insulation against heat losses. Consequently, the construction of a rocket stove was undertaken in this research and the thermal property tests for ash and clay-sawdust insulation materials were carried out, after which...
