In the Nigerian Bottling Company, Production planning has a fundamental role to play. In this study, the particular scenario considered concerns the Nigerian Bottling Company (NBC) with many production facilities and multi-products production systems. The Products are being distributed to a number of depots at which the demand for each product is k... Continue Reading
Efficient Handover mechanism in a GSM network is one of the parameters critical to GSM network service quality (QoS) and customer satisfaction. Handover is the process that transfers an ongoing call from one cell to another as the users move through the coverage areas of the cellular systems. This research focuses on analyzing and optimizing interc... Continue Reading
The overflow characteristics of semi-circular crested weir models were investigated. Twelve models were fabricated and tested. The models were categorized into two groups; normal weirs and oblique weir models. Both group of model had constant weir height and had the crest radius varied three times; 5cm, 7.5cm and 10cm. However, for the oblique weir... Continue Reading
This research work was carried out to study the effects of seawater, 0.5M hydrochloric acid and wet steam corrosive media on the fatigue strength and microstructure of welded austenitic stainless steel. The immersion time in the corrosive media was 30 days to simulate the effect on stainless steel structures/equipment in offshore and food processin... Continue Reading
This thesis studied the behavior Corn Cob Ash (CCA) concrete. The study also investigated the effect of Corn Cob Ash on cement and as a partial replacement for cement. The behavior of Corn Cob Ash concrete in aggressive chemical media was then investigated. Chemical analysis of the CCA to determine the elemental oxide composition revealed that it w...

A laboratory Investigation of the Strength Characteristics of Latecrete materials was carried out. The laterite used falls under AASHTO soil classification A-7-6 (10) with low plasticity clay (CL) according to the Unified soil classification system. This laterite is within zone four gradation characterized by fine laterite and has kaolinite as its ... Continue Reading
The work seeks to address environmental issue through the design and development of a carbonator for CO2 capture. A fixed bed carbonator with height 1.7 m and diameter 0.9 m for CO2 capture was successfully designed and fabricated at a flow rate 7.9g/hr of carbon dioxide using 2kV household electric generator as a source of flue gas. The flue gas w... Continue Reading
This research work presents the design concept, construction and performance evaluation of a 10kg capacity portable crucible furnace which uses charcoal as fuel. The 10kg crucible furnace was designed, constructed using locally available engineering materials mild steel sheet of 3 mm, mild steel (angle iron) of 5 mm, scrap aluminum, asbestos, clay ...

Car surfaces are vulnerable to scratches from environmental conditions, thereby prompting car users to visit car workshop for re-spray. This process does not usually bring permanent solution to scratches on car surfaces since they are often re-spray with non-self-healing paint. The aim of this work was to develop self-healing car paint. In doing th... Continue Reading
This work wasaimed at the design and fabrication of a pilot scale reactor for the production of aluminium hydroxide from aluminium sulphate obtained from Kankara kaolin for use in Zeolite Y synthesis. XRD, XRF and BET analyses were carried out on the aluminium hydroxide first prepared at bench scale and pilot scale. The aluminum hydroxide precipita... Continue Reading
The opportunistic network is one of the most interesting evolution of Mobile Ad-hoc Network (MANET).In an opportunistic network,information about the context in which users communicate is notavailable as there is no dedicated complete path from a source to a destination. This makes the design of an efficient routing protocol for an opportunistic ne... Continue Reading
One of the major problems facing commercialization of fuel cell systems, especially polymer electrolyte membrane (PEM) fuel cell systems is cost. Various researchers have reported different system configurations which perform differently in terms of energy utilization and cost. It is therefore important to determine the best system configuration in... Continue Reading
The research work is centered on the failure analysis of the as-received locally produced grinding plates, development of high wear resistant grinding plates capable of grinding gold-bearing mineral deposit in Bagega village of Zamfara State. The work was carried out by evaluating the chemical compositions of the as-received grinding plate samples,... Continue Reading
The desirability for new induction machines that possess the combined advantages of the well-established wound-rotor and squirrel-cage induction machines have motivated considerable research interests in the development of dual-stator induction machines. Although extensive literature survey has revealed considerable advancements in the design archi... Continue Reading
An experiment was conducted to determine the optimum irrigation schedules for tomato production under fadama conditions in Guinea Savannah region. The experiment consisted of five (5) levels of soil moisture replacement (100%, 80%, 60%, 50% and 40%) and three (3) levels of irrigation interval (3 days, 5 days and 7 days). The treatments were replica... Continue Reading
