Abstract A Wind tunnel is a mechanical assembly used to analyze the behavior of air flow and the effects they have over objects. Using a wind tunnel, one can control the stream conditions which influence forces on the test object. Through the calculations of the forces on the model, one can anticipate the forces on the full-scale test object. In the beginning, wind tunnels were used to utilized to comprehend and improve the execution of airplanes. Over the years, cars, bridges, and building w...
ABSTRACT In search for an alternative source of energy and also in order to utilize the shea waste in an appropriate way and to reduce its negative impact on the environment, the waste was investigated to identify its potential in methane generation through anaerobic digestion. The basic raw materials for the study were shea waste and cow dung. Input substrates were prepared with addition of predetermined amounts of water to bring the substrates to the required organic dry matter (odm) conc...
Abstract The leading cause of child mortality globally is prematurity. These deaths mostly occur due to unavailable or high cost of keeping babies in clinical incubators, which provide controlled environment for premature neonates. The aim of this project is to develop a cheap and portable wireless incubator for premature babies. The project focuses on reducing the causes of preterm death and, as such, incorporates measures to minimize such factors. Hence, the incubator’s other functions ar...
Abstract Green roofing is a relatively new approach toward constructing environmentally friendly and sustainable roofing structures. Not only are these structures environmentally friendly, but they can be manipulated for the purposes of energy harvesting, thermal insulation or cooling while saving cost in the long run. Much like the green roof approach, this project seeks to create, for an African setting, with a case study in Ghana, a less costly alternative to durable roofing options such a...
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. We briefly present the motivation, architecture and usage experience as well as proof statistics for a new Rodin Platform proof back-end based on the Why3 umbrella prover. Why3 offers a simple and versatile notation as a common interface to a large number of automated provers including all the leading SMT-LIB and TPTP compliant tools. The plug-in can function either in a local mode when all the provers are installed locally, or remotely as a cloud service. We discuss the experience ...
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...
