The search for an alternative to the conventional way of treating soil for use in road work, informed laterite soil sample classified as A-7-5(11) on AASHTO soil classification system, collected from a borrow pit at Shika, along Zaria-Funtua road in Kaduna State of Nigeria was pretreated with heat and stabilized with bitumen. Sample of the laterite... Continue Reading
This research presents the development of a Discrete Firefly Algorithm (DFA) based feature selection scheme for improved face recognition. Discrete Cosine Transform (DCT) and Haar wavelet based Discrete Wavelet Transform (DWT) were used for feature extraction, and Nearest Neighbour Classifier (NNC) was used as classifier. Extracted features are mos... Continue Reading
This research work is aimed at the development of an optimal extracted feature classification scheme in a voice recognition system using dynamic cuckoo search algorithm. This minimized error mismatch in the recognition process and increased accuracy of recognition. Standard voice dataset was obtained from English Language Speech Database for Speake...

Among other ways of effective water management strategies is the use of drip irrigation system and adoption of deficit irrigation schedulling strategy which is not common in the study area. Effective water management is a key to improving agricultural water management, enhancing crop production and improved sustainability of irrigated agriculture. ... Continue Reading
This research is aimed at the modelling and structural analysis of the ball-on-sphere system using bond graph technique. To achieve the bond graph model of the ball-onsphere system, the various subsystems, storage elements, junction structures, transformer elements with appropriate causality assignments and energy exchange that make up the ball-on-...

In this study, coconut palm wastes were obtained, washed to remove sands and debris and then dried at 95oC for 1 hr to remove surface moisture. Filler modifications through carbonisation were done at varying temperatures of 300oC, 400oC, 500oC, 600oC and 700oC. Both raw fillers and carbonised fillers were ground to achieve 100 ?m particle sizes, af... Continue Reading
Urine and stool samples were collected from 540 students (9-14 years) in at Dakace district in Zaria Local Government Area of Kaduna State. The samples were examined for urinary and intestinal Schistosomiasis infection. Each student was interviewed and data collectors used a structured pre-tested questionnaire that included questions on socioeconom... Continue Reading
This work focused on the production and testing of biodegradable grease from Balanites aegyptiaca seed kernel oil. This was carried out by extracting the oil from the seeds using solvent n-Hexane extraction and reacting a given quantity of the extracted oil with a lithium soap to produce a lithium based biogrease. Consistency tests, drop point as w... Continue Reading
This research work presents the Application of Cuckoo Search Algorithm for the simultaneous placement of distributed generation units and shunt capacitor banks in radial distribution networks. The approaches used in most literatures for determining the optimal allocation of DG units and Capacitor banks did not consider the simultaneous placement of... Continue Reading
A solarbox cooker is a device that converts solar energy into useful heat in a confined space. The solar cooking system which captures and utilizes the abundant solar energy was designed, simulated, constructed and tested. Plane reflectors were used to concentrate solar radiations continuously on the collector which result to heat gain. It is usual... Continue Reading
A model of transitional probability matrix for Mechanistic-Empirical Pavement Design was developed with the aim of tarnishing the traditional method obtained from the judgment of an expert panel. The model was developed using fatigue and rutting as the critical factors in pavement failure. Model performance was assessed using first order reliabilit... Continue Reading
The existing IAR multicrop thresher was evaluated and found to have low feed rate and output with millet and soybean crops. The machine was modified and reconstructed to increase its threshing performance. Its components were increased in size and a shredder was added below the feed hopper to cut stems of crops that entangle the threshing cylinder ... Continue Reading
This research presents the development of a modified token-based congestion control scheme with adaptive forwarding mechanism (mTBCC) algorithm for addressing congestion problems in opportunistic networks (OppNets). The algorithm addresses the limitations associated with the standard token �“based congestion control (TBCC) in terms of its ability ... Continue Reading
Electricity demand forecasting is a central and integral process for planning periodical operations and facility expansion in the electricity sector. Demand pattern is very complex due to the highly unpredictable behavior of consumers load consumption. Therefore, finding an appropriate forecasting model for a specific electricity network at peak de... Continue Reading
This research sole aim is to improve on the development of conceptual procurement models that can create direct and indirect impacts of various forms of plant and equipment procurement in Kaduna state Tertiary Institutions in relation to, need assessment, delay in completion, costs and non-conformance with specification by suppliers and installatio...
