ABSTRACT An Automated toll collection system is the system that helps in eliminating the heavy traffic caused in the Metropolitan countries. It is one of the flexible methods used to manage the flow of traffic in big cities of today. An Automated toll collection system is proposed, and the RFID technology is used. It is an innovative method that uses electromagnetic waves to easily identify and track the tags that are attached to the windshield of the vehicle. The main focus of this project i...
ABSTRACT Chaos is one of the most important behavioural modes exhibited by dynamical systems and refers to the unpredictable, seemingly random, motion of trajectories of a dynamical system. In recent time, non-linear dynamics and chaos have become familiar in the technical vocabulary of most sciences and technology due to the various applications of chaos in these areas. Chaotic systems display chaotic behaviours only for specific range of values of their parameters. It is therefore important...
ABSTRACT Secure communication systems employing chaos have recently attracted significant interest. This is partly due to their high unpredictability and simplicity of implementation over conventional secure communications systems. This study presents the implementation of four chaotic modulation techniques employing Lorenz system as chaos generator. The techniques are Chaotic Masking (CM), Chaos Shift Keying (CSK), Chaos On-Off Keying (COOK), and Differential Chaos Shift Keying (DCSK). Simul...
ABSTRACT There is much concern about the fossil fuel exhaustion and the environmental problems associated with conventional power generation. PV systems are the most direct way to convert solar radiation into electricity and are based on the PV effect, which was first observed by Henri Becquerel in 1839. It is quite generally defined as the emergence of an electric voltage between two electrodes attached to a solid or liquid system upon shining light onto this system. Practically, a...
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. 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 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 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 Traffic management systems at road intersections of most African cities is based on fixed timings where equal length of green light is assigned to each lane at the intersection. This method of traffic management is inefficient because it causes unnecessarily long waiting times for vehicles at the intersections especially during periods when some lanes have few or no vehicles passing through them. In this project, an affordable density based traffic management system is designed and i...
Abstract Travelers without prior information about the bus they are waiting, often waste time at bus stations which affects their day activity plan. GPS receivers are used to address this problem by providing real-time about the location of the bus, however, it is quite expensive and power consuming to use and every bus needs to have a GSM/GPRS module to be able to send the information to the internet. This project suggests a low-cost and less power consuming approach of using LoRa technology...

Abstract Compound housing is a housing arrangement that stemmed from cultural family living settings. Over the years, it has evolved to denote a group of different households that share a number of utilities including electricity. Electricity bills and payments are a concern in such living units due to the inability to split bills fairly. Previous work done to solve this are either expensive, or do not take into consideration the complexity of electricity connections in such houses. This thes...
