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 Following the dreadful gas explosion at Atomic Junction, Accra-Ghana in the year 2017[2], the innocent public and owners of gas filling stations across the country continue to face fear in managing Liquified Petroleum Gas (LPG) filling stations. Gas explosions have caused loss of precious lives and huge economic loss to owners of gas filling stations and the government. In the past four years, the rate of fire explosion in Ghana has plummeted steadily and if measures are not put in p...
Abstract Building and maintaining infrastructure is often a key challenge in developing countries, and Ghana is no exception. Increasing population and car ownership rates coupled with poor maintenance cultures result in a corresponding increase in the rate of damage of roads, causing deformities such as cracks and potholes. These road deformities not only negatively impact a country’s road infrastructure and the cars which ply said roads, but also pose a threat to road users. In Ghana, onl...
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 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 Research has shown that USSD applications utilize outdated encryption techniques, which make it susceptible to hackers during data transmission; they are unreliable and have long processes before payment is conducted.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 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 Electronic devices comprising of non-linear components (diodes, transistors, transformers, etc.) produce some number of harmonics in our power systems creating various voltage distortions [7]. As a result, several technical problems may arise for the device such as overheating and damage to sensitive equipment which would most likely lead to lifetime reduction to the customer’s devices. To reduce the likelihood of these undesired happenings, this project seeks to develop a digital...
Abstract Artificial Neural Networks (ANNs) is a branch of Machine Learning that has seen recent widespread adoption for solving computational problems that seem impractical to solve with traditional algorithmic approaches. ANNs have achieved high accuracy on tasks such as facial recognition, object detection and speech recognition. And recently, ANNs have also seen applications in embedded systems, where it has been used to train robots to learn from their environment and cameras to detect fa...
Abstract Location-based services have become very popular globally and with the increasing rate in car theft in Ghana, it is necessary that such services be implemented. Vehicle tracking is an application of the Internet of Things (IoT) proposed in aiding in the recovery of stolen vehicles. This thesis presents a detailed description of the development of a lowcost real-time GPS/GSM vehicle tracking system based on an Arduino Uno board. The system uses GPS services in determining the location...
ABSTRACT As the nation’s economy has tightened, managers of retail businesses have been greatly challenged in recent years to become more strategic in their planning. These managers need fast, reliable and interpretable analysis of different transaction data in order to effectively assess the performance of their business organizations. The introduction of computerized Point-of-Sale terminals has made it possible for retailers to easily accumulate large stores of sales data. This wealth...

ABSTRACT This project involves the design and implementation of an intelligent obstacle-avoiding robot car. The objective of this project is to implement a robot car, which while moving should have the ability to detect obstacles in its path and change direction where obstacles are present without any form of external influence. The new direction to be taken to avoid collision is the direction that has the most distance between the obstacle and the sensor and this is determined by the robot b...
The explosive growth of video data necessitated the need for large amount of storage devices. Nonetheless, the stored multimedia data has a lot of redundant video frames. These redundant frames make video browsing and retrieval difficult for the user as well as time consuming. Thus, negatively affecting bandwidth utilization and storage capacity. In order to improve the bandwidth utilization and storage capacity, keyframe extraction algorithms were proposed. These algorithms were implemen...
This project- construction of a digital voltmeter seeks to utilize the microcontroller to build a digital voltmeter having better accuracy by utilizing a successive approximation analogue to digital converter ADC to measure the voltage (0 – 250V). Here, the working principal and components of this device are extensively explained. This Digital voltmeters (DVM) display the measured voltage using LCDs (Liquid Crystal Display) to display the result in a floating point format.
Abstract Ferroelectric RAM or FRAM or FeRAM is one of a growing number of alternative non-volatile random-access memory technologies that offer the same functionality as flash memory. It combines the fast read and write access of dynamic RAM(DRAM) - the most common kind of personal computer memory - with the ability to retain data when power is turned off (as do other non-volatile memory devices such as ROM and flash memory). Because FRAM is not as dense (cannot store asmuch data in the same ...
