Abstract This report presents the optimisation of a ceramic-matrix composite (anthill sand and cement), reinforced with treated coir fibres for applications in the construction of a low costsolar powered cooking stove to solve the current trends in the depletion of forest spaces in Ghana due to excessive destruction as a result of using firewood for cooking by a higher percentage of rural communities. The reinforced coir fibres reduce undesirable traits in ceramics including, low fracture tou...
Abstract Streetlights are public goods that beautify cities, ensure safety for road users and security for city neighborhoods. A delay in streetlight maintenance jeopardizes the safety and security of many. Also, when streetlights stay on throughout the day, it wastes power and energy and increases cost. This project presents the design of a low-cost streetlight monitoring system based on LoRa technology. In the design, a Dragino LoraWAN 868MHz (LoRa/GSM) gateway module was used alongside one...
Abstract Fossil Fuels are currently classified as some of the leading producers of greenhouse gases which are major agents of Global warming. This study establishes the benefits Liquified Natural Gas (LNG) would have when used as a fuel in a hybrid-electric vehicle. The study establishes a Parallel-Hybrid vehicle model equipped with a control system to determine the mode of operation of the vehicle. Simulations using the vehicle models developed were performed in AVL Cruise. The results gener...
ABSTRACT PV modules exhibit a point at which its power is maximum; this point is called Maximum Power Point (MPP). Due to changes in weather conditions, the MPP changes and the PV module efficiency. Specifically, temperature and irradiance are the parameters that affect the solar panel characteristic properties. This project describes and implements an MPPT algorithm that tracks the MPP at every point in time depending on the load. The algorithm was modeled using MATLAB Simulink and tested un...
Abstract The issue of vehicle accidents occurring on the roads on a daily basis, which only seems to be increased by the minute is what this paper researches and seeks to tackle. With the simple technology that has been made available globally, a cost-effective system can be developed to fight overspeeding, reduce road accidents and save lives. As a result, in this project, an Automatic Number Plate Recognition program and a web service for speed detection were implemented. This was done with...
Abstract The Ghanaian transit system poses certain challenges to users, as it usually has passengers waiting at bus stops for a bus to their destination, for an unknown amount of time because there is no means of tracking the buses. The system is also problematic as passengers usually argue with bus conductors for change, when payments are made in high denominations, because there are no cashless payment methods available. This makes planning of journeys difficult to users of this system. Exi...
ABSTRACT This study examined gender influence on role performance in PR departments in the Ghana Commercial Bank, the Electoral Commission and the University of Ghana. The study was undertaken within the framework of the social role theory. A combination of qualitative in-depth interviews and observation was employed to gather data using Frederick‟s nine-item list of activities and Alimo-Metcalfe‟s four-item list of leadership styles. The study found that male and female managers appeared...
ABSTRACT The Nigerian Electricity Supply Industry is currently under reforms due to inadequate power supply to meet basic needs.
ABSTRACT Linear fractional programming problems are useful tools in production planning, financial and corporate planning, health care and hospital planning and as such have attracted considerable research interest. The paper presents a new approach for solving a fractional linear programming problem in which the objective function is a linear fractional function, while the constraint functions are in the form of linear inequalities. The approach adopted is based mainly upon solving the probl...
ABSTRACT With high solar radiation across Nigeria, solar power system can become a viable solution to the Nigeria's electricity power crisis if the problem of high capital cost of solar power supply system can be addressed. In this study the use of demand management based design approach has been explored for reducing the capital cost of residential solar power supply system. Utilities and energy demands of thirty randomly picked homes in selected residential areas were studied The houses wer...
ABSTRACT In this study an attempt is made to use the Artificial Neural Network (ANN) model predict the Mean Time between Failures of manufacturing equipment. The equipment failure pattern was carefully studied and some key factors affecting the Mean Time between Failures were identified. An Artificial Neural Network model, the Multi-Layer perceptron, with two hidden layers and seven processing elements was built. Twelve months of maintenance data of the machine was collected. The data items w...
Abstract This research presents a conceptual procedure for characterizing the essential nature of the diagnostic reasoning process. This computerization of the medical neurological section of the University College Hospital Ibadan in Nigeria leads to effectiveness and efficiency of the existing medical diagnosing process. The main purpose of this project is to design a computerized brain diagnosing system that would be used in carrying out the daily diagnosing activity in the clinic. The dev...
ABSTRACT This study reports an investigation of the effect of carburizing variables - temperature, time and percentage of energizer --on the case properties of C2R steel obtained from HMT Ltd. India. A carburizer consisting of hardwood charcoal and coke respectively in the ratio of 2: 1 was used for the research with sodium carbonate as the energizer. The carburizing box was filled with 20 mm thick carburizer compound prior to fixing the steel samples in place. The specimens were carburized ...
ABSTRACT Filtrate losses and filter cake properties of drilling fluids are of concern in the oil industry because they alter near well bore permeability and can reduce well productivity. Therefore, it is desirable to accurately characterize filtration process during oil well drilling. A mathematical model for analyzing mud filtration in deviated wells was developed in this study. The model determined solid pressure distribution within cake, cake thickness, cumulative volume of filtrate and e...
