Abstract Consumers’ complaints of estimated bills from the Utility have risen to an alarming extent in recent years. On the other hand, Utility incurs huge losses attributing it to electric energy consumption theft among consumers. These complaints by the utility and the consumer led to the quest for a system that in addition to recording energy consumption data, will be able to compute and report the data to the Utility remotely. This work proposes the implementation of smart meter which...
ABSTRACT This project work covers the design and construction of a robotic arm mechanically capable of 5 Degrees of Freedom. It solves the problem of automatically detecting and picking up objects placed within distances of 10-30cm round the robot base platform. It does this by using a simplified forward and inverse kinematic relation modeled in two dimensional robot workspace. The work does not cover the more general case, of an n-linked (n>2) robotic arm working within a three dimensional...
ABSTRACT This project presents a 40A maximum power point tracking solar charge controller. The MPPT charge controller tries to keep the voltage and the power stable. The MPPT charge controller will harvest more power from the solar array – it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement of the battery plus load. An MPPT charge controller is an electronic DC to DC converter that optimi...
ABSTRACT The problem of epileptic power supply and its consequences in the developing countries is a generally known issue. Worst still, the hope that it will be addressed with the deregulation of electricity Industries in recent time are being dashed by flight to top class investors due to its poor implementation. There is a need to provide multiple sources of power and automatic mechanisms for switching from one source to another. This is achieved in this work where quadruple power supp...
ABSTRACT This study presents the modelling and optimization of a Hybrid Energy System (HES) for GSM Base Transceiver Station (BTS) sites in emerging cities. The aim is to ensure reliable and cost-effective power supply, considering the availability, dynamism and viability of energy sources. Theoretical approach is applied in the modelling, simulation and validation of the developed HES, which consists of the utility grid, wind and solar photovoltaic (PV) as primary energy sources incorporati...
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...
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 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 The development of any nation and its economy at large is centred on reliable and efficient power supply. Many developing nations are yet to actualise this feat, and therefore, there is need to strategize to meet the ever-rising demand for energy. Battery-based inverter systems have over the years provided additional power supply to critical loads, in the absence of public power supply. However, high peak charging/discharging power demands results in the degradation of the battery. A...
Abstract This work involves the design and development of a digital signal detector which is capable of detecting incoming and outgoing signals from mobile phones. The presence of an activated mobile phone can be detected by this handy, pocket-size mobile signal detector from a distance of one and a half meters, which could be used in preventing the use of mobile phones in examination halls, classrooms, confidential rooms etc. The circuit can detect the incoming and outgoing calls, tex...
Abstract Human Computer Interaction now focuses more on being able to relate to human emotions. Recognizing human emotions from speech is an area that a lot of research is being done into with the rise of robots and Virtual reality. In this paper, emotion recognition from speech is done in MATLAB. Feature extraction is done based on the pitch and 13 MFCCs of the audio files. Two classification methods are used and compared to determine the one with the highest accuracy for the data set.
Abstract Waste management is a raising concern faced by many nations in the world today. On the streets of major cities, it has become almost common to find waste which poses health hazards and other concerns to its communities and inhabitants. This project focuses on the use of smart systems and the Internet of Things (IOT), to provide an efficient and effective approach to waste management. This project designed and manufactured a prototype of a solar powered, self-compacting smart bin with...
Abstract The increasing demand for electricity in Ghana has led to concerns about energy conservation, to reduce the rising energy costs as well as the carbon emissions produced from energy generation. Popular energy conservation methods used in Ghana include turning off devices when not in use and using Light Emitting Diode (LED) lamps in place of incandescent bulbs which consume more power. However, these methods do not have very significant results and are not very efficient. Additionally,...
Abstract Music is a very important part of the Ghanaian society and it serves many purposes. In more recent times, the guitar has been one of the most widely used melodic instruments in music production. With the invention of the effect pedal, guitarists worldwide have been able to use a wider variety of tones to produce more complex and enjoyable music. In Ghana, however, these pedals need to be imported and this prevents a lot of guitarists from having a lot of tones to choose from which im...
Abstract Cowpea traders find the manual sorting process of cowpeas laborious and time-consuming. Based on the volume of cowpeas and the proportion of damaged cowpeas, the process can span a time interval of about 6 hours. This project integrates the power of computer vision and convolutional neural networks to develop a solution for the cowpea trader to effectively segregate good cowpeas from the damaged ones.
