The study was conducted to investigate some physical properties of soybean at three moisture levels (10, 12 and 14%) and also to modify an existing soyabean thresher developed by Amadu, (2012) which has a low output capacity (25.5 kg/hr) and a major problem of chocking during threshing operations. The average length, width and thickness of soybean ... Continue Reading
In this study, a simple four-mould hydraulic piston press biomass hollow briquette making machine, suitable for household and small-scale production of circular briquettes with a centre hole was developed. The briquetting machine was operated using a 4-tons hydraulic jack. Other members of the machine include: the mould, pistons, lower and upper co... Continue Reading
There is a great deal of environmental pressure in many parts of the country to ascertain how organic waste can best be handled in the absence of appropriate disposal methods can cause adverse environmental and health problems. Anaerobic digestion has been considered as waste-to-energy technology, and is widely used in the treatment of different or... Continue Reading
An Adaptive Dynamic Scheduling Algorithm (ADSA) based on Artificial Bee Colony (ABC) was developed for vehicular traffic control. The developed model optimally schedule green light timing in accordance with traffic condition in order to minimize the Average Waiting Time (AWT) at the cross intersection. A MATLAB based Graphic User Interface (GUI) tr... Continue Reading
Optimal deployment of sensor node in other to ensure optimum network coverage is one of the challenging problems faced by Wireless Sensor Network (WSN) researchers due to the complexity and exhaustive nature of WSN. Target tracking problem is concerned with maximizing the lifetime of the network while continuously monitoring a set of targets.This d... Continue Reading
Dust carry non-spherical particles which in the absence of turbulence or shear wind and hydrodynamic forces, tend to orient their major axis in the vertical plane, thus resulting in particles anisotropy which may contribute to Cross Polarization Discrimination (XPD) degradation due to differential phase shift. This research presents an improved mod... Continue Reading
This research is aimed at the modification of the Remote Access Dial in User Server (RADIUS) protocol with the one-time password (OTP) technique for the authentication environment with a captive portal to prevent replay attacks. One of the important network security measures on a campus network is the use of authentication for identification of leg... Continue Reading
Investigations were carried out for heavy metals composition of ambient air using a special instrument designed for this purpose. The lack of portable air sampler is a major obstacle to air pollution studies in Nigeria of recent. As a remedy to this, a simplified air sampler was designed and fabricated at the Water Resources and Environmental Engin... Continue Reading
The study was aimed at the evaluation of the effect of iron ore tailings as an admixture in cement stabilization of lateritic soil. Air-dried soil was treated with ordinary Portland cement (OPC) �“ iron ore tailing (IOT) blend in stepped concentration of 0, 2, 4, 6 and 8 % by dry weight of soil for OPC and 0, 2, 4, 6, 8 and 10 % by dry weight of s...

To utilize the economic benefits of elephant grass (pennisetum purpereum) and exploit its potential as biomass for glucose production, the kinetic model for the production of glucose from the grass was investigated at the optimum conditions of hydrolysis (pH 4.5, temperature 45 oC, time 24 hours). The grass was characterized, pretreated and then hy... Continue Reading
Grey water is the left over water from baths, showers, hand basin and washing machine; in some cases water from the kitchen sink. The use of some synthetic chemical reagents in the treatment of grey water has been reported to be cancerogenic. The present study is an investigation into the possibility of using environmental friendly substances like,... Continue Reading
This research was conducted to investigate the suitability of using a renewable, sustainable and environmentally friendly biodiesel as part or full substitute of the petroleum diesel. Biodiesel from Cotton, Jatropha and Neem seeds, were produced and their compositions were analysed using Gas Chromatography-Mass Spectroscopy. The biodiesels were the... Continue Reading
Proportional-Integral-Derivative (PID) controllers have been widely used in process industry for decades, from small industry to high technology industry, but they still remain poorly tuned by use of conventional tuning methods like the Zeigler-Nichols method. In this work, PID controller’s parameters for deep space antenna positioning system wer... Continue Reading
Modern electrical devices such as Compact Fluorescent Lamp (CFL), many of which are non-linear loads inject harmonics into the Power Distribution Network (PDN). For the devices to operate efficiently as well as reduce electricity consumption and environmental impacts without introducing undesirable side effects, such as harmonics into the distribut...
