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 rationale for this project is to design a public health communication strategy for campaign on sickle cell anemia in Ghana. This project has been necessitated by the alarming rate at which the condition is occurring. It is generally estimated that 2% of children born in Ghana each year have a form of the sickle cell disease. This proportion is more than that of HIV/AIDS in the country (Ohene-Frimpong, 2011). In recent times, due to technological advancement, it is possible to det...
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: The purpose of this study is the preparation of activated carbon using a suitable industrial sludge. The characterization of two types of industrial sludges showed that paper sludge was a better option over rice husk. The activated carbon produced from pyrolysis of paper mill sludge was chemically activated with various activating agents like zinc chloride, potassium hydroxide and potassium chloride. A systematic investigation of the effect of impregnation ratio, activation temp...
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 The project proposed a method of reading individual energy consumption by tenants living in a compound house but share a single meter. The smart energy monitor was designed using ATmega8, SIM800l, PZEM004T, I2C LCD ,SCT-013-000 current sensor. The smart energy monitor solves the problem of bill sharing in compound house that share one meter. The printed circuit board was design ed using Eagle and the program for the system was programmed in the Arduino IDE in c language in Arduino sy...
Abstract Accessing remote health care from public hospitals in Ghana has become more difficult and expensive recently due to the increasing number of patients that surpass the low number of doctors in the country. Many people have lost their lives waiting in long vital checking lines just to take their vitals in some hospitals. However, with the help of the Internet of Things (IoT), this report provides a design of a low-cost remote health monitoring system for patients with chronic diseases ...
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 This paper explores the current flaws of the undergraduate syllabi treating Industrial Automation and Control. It elaborates on the disparities between the current syllabi and what is used in Industry; particularly the current trend of Industrial Automation. It looks at the effect of not meeting this trend in Industry and thus offers a solution in the form of another curriculum, which incorporates concepts of Industrial Automation 4.0 which are necessary for the workplace. It uses th...
Abstract Aquatic search and rescue in Ghana and most parts of the world poses lots of disadvantages to the rescuers. Divers being tasked for each search and rescue mission risk their lives trying to locate a body or an object underwater. Sometimes, these divers are attacked by aquatic animals or even hit by submersible objects. This approach is also problematic since divers are not able to stay longer under water due to fixed oxygen tanks. This limits their search periods as they ought to res...
Abstract Industrial accidents are on the rise. This fact is even more prevalent in developing countries where the countries lack the safety standards required to ensure workplace safety in the pursuit of economic development. As land in prime locations becomes increasingly scarce, there is an argument for building skyscrapers. But this just creates a new workforce that are subject to the horrific dangers of cleaning glass panels at heights well above the ground. In this applied project, I des...
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 In Ghana and other parts of Africa, most traffic management systems are implemented by the use of a timer at each phase. This method of traffic management is inefficient because equal length of green light is assigned to each lane at the intersection; resulting in long wait times for vehicles behind a traffic light with the red signal on, especially when other lanes are vacant. This project addresses problems such as the one stated in the previous sentence through designs and impleme...
Abstract The objectives a welding flux is expected to achieve are many and often mutually incompatible.
