Cognitive radio (CR) has been suggested as the solution to spectrum scarcity due to the fixed allocation employed worldwide by regulatory bodies.A secondary usercan opportunistically access the licensed frequency bands without causing harmful interference to the licensed user. In order to avoid interference to a primary user signal,the CR has to be... Continue Reading
In the bid to find solutions to the problems associated with planting on ridges and for the fact that existing planters for cereals in Nigeria are not built on the concept of ridges but on flat land planting, this research work was embarked upon to develop anengine-propelled two-row ridge planter for cereals. The planter was designed, fabricated an... Continue Reading
In this dissertation a Clonal Selection Algorithm (CSA) based system that detected multiple instances of circles, quadrilaterals and triangles in an image scene was developed. CSA models how B-cell antibodies of the immune system protect the body from invading antigens. The developed system eliminated the need for separate implementations of the CS... Continue Reading
This research presents the development of a Frangi filter and first-order derivative of Gaussian (FF-FDOG) based power line detection (PLD) algorithm as an improvement to the standard PLD algorithm. Vision-based PLD is important in obstacle avoidance in low-altitude flight and also in the surveillance and maintenance of electrical infrastructure. T... Continue Reading
The problems of low mechanical properties of composites reinforced with fibres of natural origin have been a source of concern for researchers. Also, the insufficient utilization of bagasse fibres due to its moderate strength has further reduced its potentialities in composite production hence the need to hybridize with other fibres. In this work, ... Continue Reading
This research presents the development of an improved Extended Dijkstra Algorithm (mED-SDN) for Software Defined Networks (SDN) using Representational State Transfer (REST). The original Extended Dijkstra Algorithm for SDN (ED-SDN) cannot handle shortcomings associated with the traditional shortest path routing used in SDN. The traditional shortest... Continue Reading
The study investigates the suitability of ceramic waste aggregate (CWA) as partial replacement for coarse aggregate in asphalt concrete. In order to achieve the aim of the study, consistency tests such as sieve analysis, aggregate crushing and impact value, water absorption, particle shape (flakiness and elongation) and specific gravity were conduc...

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
