A SMART BREATHALYZER SYSTEM FOR GHANA

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...

Recycling of Plastic Waste Material: Mechanical Properties and Implications for Road Construction

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...

Location Determination Algorithms

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...

Fabrication of 3D Printed Scaffolds for Tissue Engineering: Understanding the Mechanical Stability, Degradation Mechanisms and Biocompatibility.

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 ...

DESIGN AND FABRICATION OF A SOLAR-POWERED ELECTRIC STOVE FOR RURAL AND URBAN COMMUNITIES OF GHANA

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...

DESIGN OF A LOW-COST STREETLIGHT MONITORING SYSTEM USING LORA

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...

Performance of a Parallel Hybrid Electric vehicle with Liquefied Natural Gas

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...

Maximum Power Point Tracking of Photovoltaic Systems for Rural Applications

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...

DESIGN AND IMPLEMENTATION OF A SPEED DETECTION SYSTEM USING RADAR AND IMAGE PROCESSING

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...

A TRACKING AND BILLING SYSTEM FOR COMMERCIAL VEHICLES

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...

A STUDY OF GENDER ROLES IN PUBLIC RELATIONS PRACTICE IN GHANA

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...

DESIGN OF A BIOMASS POWER PLANT FOR MAJOR COMMERCIAL CLUSTER IN IBADAN, NIGERIA

ABSTRACT The Nigerian Electricity Supply Industry is currently under reforms due to inadequate power supply to meet basic needs.

An Approach for Solving Linear Fractional Programming Problems

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...

Demand management based design of residential solar power supply system: a techno-economic evaluation

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...

Predicting mean time between failures of a maintained equipment using artificial neural network

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...
