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...
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 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 Working adults and university students find it difficult to complete their laundry in a day because of the unpredictable weather conditions in the tropics of West Africa. There are existing drying machines, but these machines are either not smart or they are hard to install and maintain and they cause easy damage to the clothes. In comparison to the United States where electric drying is mostly used, about 16 billion kW is consumed per year or 5.8% of the whole resident electricity c...
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...
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 This paper reviewed and analysed vulnerability to climate change-induced rainfall variability and policy responses to agricultural water supply in Nigeria. The review provides evidence for policy feedbacks as well as priority setting for the post-2015 sustainable development agenda. Nigeria’s vulnerability to climate change variability is due to a number of factors: its geographical characteristics, limited capacity to adapt, dependence on climate-sensitive resources, teeming popul...
ABSTRACT A review of face recognition techniques has been carried out. Face recognition has been an attractive field in the society of both biological and computer vision of research. It exhibits the characteristics of being natural and low-intrusive. In this paper and updated survey of techniques for face recognition is made. Methods of face recognition, such as, geometric, statistical and neutral network approaches are presented and analyzed. The comparative performance of the various appro...
ABSTRACT This study is about the use of automated material handling 5ystem to eliminate bottlenecks on production line In order to achieve higher system capacity utilization. It was applied to the milling plant of a food processing company. Detailed study of the milling plant work system's parameters was carried out to give a basis for the selection of a suitable new transfer system Facility layout analysis to determine floor space requirement. as well as work system design analysis and cost/...
ABSTRACT ABSTRACT The safety plugs presently used on our equipment-in the Nigerian industries are wholly imported. This research is aimed therefore at developing safety fuse plugs, using locally available materials that will compare favourably with the imported safety fuse plugs. Minerals from various mining sites in the country and laboratory samples were collected. Beneficiation processes were carried out on the samples using foundry equipments which included electric furnace, tongs, and cr...
