Abstract This project paper explains the design and fabrication of an inflatable wing using a flexible, low cost and easily accessible PVC material. In recent times, several researchers have explored the building of inflatable structures using expensive and high strength materials like Mylar and Kevlar. However, this project scope was contextualized in the East African region where there is need for flexible and low cost Unmanned Aerial Vehicles (UAVs) for applications such as military survei...
Abstract In traditional Internet of Things (IoT) systems, users are unable to authorize and/or deauthorize the collection of user data. Hence, the problem of the absence of user autonomy in IoT systems. The project aims to tackle this problem by suggesting a human-centered privacy-by-design option in the design and implementation of IoT systems. It aims to prioritize the need for the privacy of the user in designing IoT systems. It proposes to do this through the provision of user autonomous ...
Abstract Hydroponics, a system of growing crops without soil, has been successfully used to grow crops on a commercial scale. Hydroponics has the potential to fill the gap of low agricultural production in Ghana due to its high efficiency while serving as an environmentally friendly alternative to soil culture. This method of farming has benefitted from new technologies like IoT and machine learning that make it possible to integrate intelligent agents in the management of hydroponic systems ...
Abstract Following the discovery of Oil in Ghana the upstream industry of the Oil and Gas has received a jumpstart and is augmenting the older and more established midstream and downstream industry. The midstream and downstream industries involve the processes that refine, transport, and distribute oil and other crude products and as economic activities increase there is an urgent need to vamp up production, and this can be done by increasing the efficiency of storage processes. This paper ex...
Abstract Pneumonia has been the leading cause of death among children under the age of five in subSaharan Africa, killing more children than the number of children dying from HIV/AIDS. The current methods of diagnosing pneumonia are limited by poor sensitivity and accuracy and they are also expensive. In this project, a low-cost biomedical device was designed and developed to improve the accuracy in diagnosing pneumonia hence assisting in correct prescription of drugs to children. Sounds wave...
Abstract The project intends to increase vehicle operator awareness with the integration of a Low-Cost Driving Assistance system in older car models. Situational awareness during driving significantly reduces the number of road traffic accidents, as proved by literature. A 4-wheel mobile robot is used as the plant representing a vehicle for easier and rapid prototyping. The plant is controlled by a Raspberry Pi3 to achieve the desired control choice as well as do all required computational pr...
ABSTRACT A vehicle tracking system is any technology that can be used to access the location of a vehicle; either in real time or offline. However, for many car owners, especially on the continent of Africa, vehicle tracking is a luxury which only a few people can afford. Many people are struggling to get a car in the first place. Analysis of vehicle theft data done in South Africa showed that most of the vehicle theft in the Southern African country are as a result of poor security systems. ...
Abstract All-Terrain vehicle as the name implies refers to a car that has been designed to handle a more extensive variety of terrains than most other cars. ATVs are used for several purposes which include recreational purposes and others ranging from military to jungle safaris and desert rides. ATVs are rated highly based on their ability to sustain irregularities of the terrain with ease. The central system involved in supplying the damping characteristics of the vehicles is the suspension ...
Abstract The use of Unstructured Supplementary Service Data (USSD) applications in conducting monetary transactions is an unsafe and slow means of payment. Research has shown that USSD applications utilize outdated encryption techniques, which make it susceptible to hackers during data transmission; they are unreliable and have long processes before payment is conducted. This study aims to explore how Near Field Communication (NFC) technology can be used to conduct payments. Comparing the two...
Abstract An analysis report compiled by the OSHA lists eighty-eight (88) window cleaning accidents over the past 15 years of which sixty-two (62) resulted in fatalities [1]. Despite these statistics and the potential for injuries and deaths, the industry considers these numbers to be artificially low. Window cleaning is still not effectively regulated, and numerous people undertake this activity in a way that endangers both themselves and the public. This project aims at removing the human co...
Abstract As the world keeps evolving, the demand for electricity increases. The growing energy consumption leads to higher cost that many people, especially in Ghanaian rural areas, cannot afford. Thus, considering this, this paper focuses on designing a Stirling engine to pump water in homes. In order to contribute to the use of renewable energy with a low carbon footprint, concentrated solar energy will be used to power this system once it is implemented. As such this, source of power was c...
Abstract Solar Energy is the fastest growing renewable energy source in the world. The soaring production and the significant technological breakthrough of solar energy in certain countries like China and India has brought about a drastic reduction in the cost of its exploitation. Today, the price of solar PV panels in China has declined by as much as 50%. Despite this immense progress in the solar energy industry, the question of how solar energy has evolved in Ghana and Africa at large, rem...
Abstract This paper describes the design and fabrication of an epileptic seizure detection watch for the timely detection of Generalized Tonic-Clonic (GTC) seizures; using skin conductance (SC) signals. The watch’s circuit was designed in EasyEDA and implemented on a Breadboard to showcase the dispatch of a seizure event alert to a phone via a Bluetooth module; in the event of an ongoing seizure and vice versa. Due to the unavailability of SC signal databases, Electroencephalography (EEG) s...
Abstract In the off-grid communities in Ghana, most people depend on solar energy for electricity [1]. Some also depend on torch lights, candle lights or kerosene lamps to meet their lighting needs [2]. These lamps come with their own pros and cons. The solar lamps for instance, do not last for the entire night when in full usage though they are the cleanest of all. And since they are solar dependent, they become useless when there is no sun shine [3]. Hence, on the event of these solar lamps...
Abstract Gari is a very important staple food made from cassava and is eaten in many parts of Africa. Gari has a granular nature and may contain different sizes of grains ranging from as small as 1 mm to as large as 6 mm. Depending on where and how gari is going to be eaten, specific particle sizes are desirable. The market value of gari is therefore reduced if a given sample to be bought has different grain sizes mixed together. To correct this, gari is often sieved into varying particle siz...
