Abstract Car theft has become prominent all over Ghana in recent years. Despite its growing prominence throughout the country, measures to promptly recover stolen vehicles have often proved tedious and futile. To tackle this problem, this project aims to develop a remote control system and a model of a GPS tracking system which would together help vehicle owners swiftly recover their vehicles should the need arise. This was achieved by developing a mobile application to serve as an interface...
Abstract Vehicles provide an efficient way of transportation across the cities of Greater Accra in Ghana. Technology has impacted the transportation sector through variety of modes such as applications for routing. An example of this is the google maps mobile application. However, due to bad road networks and a time sequenced traffic control system in Ghana, traffic congestion is a major problem during peak times of the day. In cases of emergencies where a route needs to be created for emerg...
ABSTRACT Imagine a five-year-old boy losing his life by being knocked down by a drunk driver who has been intoxicated with alcohol. The driver’s carelessness will cause the family of the little child so much pain, as well as lead to a significant loss of human resources in the country. Road accident according to research has been the second leading cause of death in Ghana. While several countries in the world invest in finding solutions to road accidents [1], little is done by the country t...
AbstractThe main purpose of the project is to convert polyethylenetetraphylate (PET), a known plastic waste material in Ghana, to wealth. Composite samples were produced by heating aggregates together with shredded PET plastic waste material, while bitumen was added to the plasticcoated aggregates. The composites produced were of 4.5 wt%, 9.0 wt%, 13.6 wt% and 18.0 wt% concentrations of PET. Mechanical and optical characterisation of the fabricated composite samples were studied for optimizat...
Abstract The public transport industry is an essential part of people’s lives. However, the problem associated with the local public transport industry is, travellers usually get frustrated when waiting for a bus to arrive at a bus stop due to uncertainty on when the bus may arrive or if it may arrive at all. This leads to anxiety on the part of the traveller as well as time wastage, especially if this was not planned for in the trip. To solve this, historically GPS receivers are used in co...
Abstract Diabetes mellitus, also known as diabetes has on major effect on its patients. This is the effect of impaired wound healing. Patients thus get minor wounds such as small cuts which become non-healing and are liable to get infected. Severe cases of such occasions lead to amputations. A solution to this problem is tissue regeneration with the help of scaffolds. These scaffolds are made of biopolymers and promote cell adhesion, regeneration and minimal diffusional constraints. Computer ...
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...
