In this thesis, a diagnostic assessment of the entire water supply distribution network was carried out in order to evaluate problems associated with water supply in Minna. This assessment was carried out by conducting inventory of all the facilities in the entire water supply distribution network by onsite, physical and visual inspection of all th... Continue Reading
This research presents the design and configuration of Multi-Protocol Label Switching (MPLS) technology to address scalability issues on a large and complex campus network such as Ahmadu Bello University campus network that is currently designed, configured and implemented with Open Shortest Path First Protocol (OSPF) network. Graphical Network Sim... Continue Reading
Enhancement of the friction-reducing properties of degraded 20W-50 engine oil by blending with neem and palm kernel oils respectively for application in cold upset-forging of aluminium alloys has been investigated using the ring compression test procedure. Three sets of blends of each of the vegetable oils with the degraded engine oil in the ratios... Continue Reading
In this research work, the optimal conditions for glucose and bio-ethanol production from Spirogyra africana were studied. The Spirogyra africana samples collected from the Ahmadu Bello University Zaria Dam were dried, milled and sieved to ? 125 ?m, and subsequently analyzed for carbohydrate content. Prior to hydrolysis, a set of the samples was pr... Continue Reading
The Swift simulative formability test was employed. in this research work for the assessment of some locally produced vegetable oils viz: Palm oil, Palm Kernel oil, Cottonseed oil and Groundnut oil as lubricants in deep drawing operations. The assessment of these local oils was based on Swift test parameters; the limiting drawing ratio and the maxi... Continue Reading
This study had investigated the admixture properties of plantain peel ash through a series of laboratory experiments. This was targeted at obtaining an effective admixture while relieving the environment from the menace of environmental pollution arising from indiscriminate disposal of agricultural wastes. Plantain peel ash was blended with dry cem... Continue Reading
This study, investigated the creep behaviour of Black Afara (Terminalia ivorensis) timber in accordance with EN 408 (2004) and EN 13153 (2002). The data were analysed based on the Eurocode 5 (2004), Eurocode 0 (2002), JCSS (2006) and EN 384 (2004) specifications using Easyfit statistical package. The statistics of the reference material properties ... Continue Reading
The effect of hot-sesame oil bath as an austempering medium for ductile cast iron was investigated. Samples of ductile cast iron were machined to standard dimensions for tensile, impact and hardness/microstructural analysis test specimens prior to the austempering process. Sesame oil was used as hot quenching bath for the austempering process. The ... Continue Reading
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
