The corrosion inhibition of aluminium and mild steel in H2SO4 in the presence of Bromothymol blue, BTB, Dimethyl yellow, DMY, Methyl orange, MO, Titanium (IV) oxide, TO and Cassia Siamea Lam, CSL leaves extract at 303 – 313K was studied using “Absorbance difference” technique. The results showed that inhibition efficiency (%IE) increased with increase in inhibitor concentration (except for BTB, where beyond a “critical” concentration of 0.0007M, it reversed its function and bec...
ABSTRACT Leaf area measurement can be a time consuming process and may require sophisticated electronic instruments. The objective of this research was to develop a simple, and less time consuming method for leaf area (LA) estimation of some leaves of cassava varieties. A method based on the beta mass absorption coefficient of the leaf has been developed and used for the estimation of leaf area of three varieties of cassava and the accuracy and precision of this method has been compared with ...
Internal sorting algorithms constitute a class of util ity programs that are widely used in performing routine computing operations . This thesis examines the t heory and structu res of these algorithms and ill ustrates their basic principles with flowcharts and tabular presentations. PASCAL codes were also developed and implemented for the methods.
ABSTRACT This thesis discusses the difficulties older users encounter with Smartphones and tablets. It goes further to discuss the possible reasons for these difficulties and also suggests a solution in form of an application which will help to improve intuitiveness in the above mentioned devices for older users.
Abstract Public health surveillance is a challenge across the globe. Unexpected disease outbreaks occur even though we have vast knowledge in the field of medicine. Also not being able to forecast the next set of diseases to be reported keeps our medical practitioners less prepared. This problem is heightened in low-income countries that cannot afford the infrastructure that comes with ubiquitous computing methods including Machine Learning on a national scale. There is also a notion that su...
Abstract The modern-day automobile is no longer just an analog and mechanical entity. Currently, the most basic of vehicular functions have been computerized. The dedicated hardware assigned to these tasks are electronic control units (ECU). Automobiles consist of a number of ECUs networked together to ensure proper functioning of the vehicle. The overall safety of the vehicle relies on real-time communication between the ECUs. Intra-vehicular communication is possible because of the Controll...
Abstract The advent of mobile gaming brought about a new age of how video games are regarded in the context of mobility. Previously, a person would have to own a specialized gaming device that enabled them play on the move. Devices such as the PlayStation Portable and Nintendo’s series of GameBoy devices made this a possibility. However, mobile games have always offered a constraint on the type of interactions they offer players. A mobile game is only as enjoyable as the quality of informat...
ABSTRACT The ability to observe current trends in health information and predict the future health status of a country is an important goal of health service institutions. Health information systems are used to accumulate, validate and examine data in order to provide information which is used in the formation of health policies. The fast growth and integration of databases means health scientists now have a huge resource that can be studied to make inferences and reveal valuable trends. Dev...
Abstract Access to potable water is a difficulty for about a quarter of the world’s population. The people living in the northern regions of Ghana, which have arid to semi-arid vegetation cover, form a significantly large percentage of that number in Ghana. Rainwater harvesting has been found to be an appropriate measure to mitigate the effects of water shortages, but its practice has also been fraught with various challenges. Advancing technology has encouraged much research into the best ...
Abstract Effective democratic governance is still gaining its roots in Ghana. With time, people have become more aware of their societies and the effort put in by their leaders to make it better. For a leader, being accountable to the people is taking steps to ensure that his or her actions and promises are binding. Accountability remains one of the challenging factors in governance because the people can assess the performance of the incumbent. This project therefore seeks to provide a syste...
Abstract Hospitals in Ghana still operate with the file-based system approach due to the absence of a health management system. While this approach works, it is an ineffective way to store and manage health records. Hospitals consume large amounts of paper in preparing medical records, lab reports, and prescriptions. With information scattered all over the place, it becomes difficult to manage and keep track of. In this paper, a solution proposed is a health management system whereby various ...
Abstract Disaster is an unfortunate, yet common phenomenon in our world today. This phenomenon stakes undesirable claims on lives, infrastructure and services alike. Those affected both directly and indirectly must overcome challenges, not only during but also, after the occurrence of disasters. Imperatively, it is always prefered to be better equipped to prevent the disaster and avoid it altogether. Yet that is impossible as not all disasters are man-made. Disaster management then must be u...
Abstract The increasing accessibility to internet resources has made several companies adopt the use of such resources in their processes. Axis Human Capital Limited, a human capital management and development company in Ghana, needed a mobile application that mitigates the problems that their clients face when using their website and has other important features that successfully support their processes and improve them where necessary. This paper proposes a hybrid mobile application, Axis M...
Abstract Machine learning and the development of Artificial Intelligence (AI) has grown nearly exponentially over the past few years. However, growing fears over the nature of AI and the use of user data by large companies has put an air of distrust over the ML community. This makes it hard to collect more data with better user representation is needed to train more useful and accurate models and creates a unique problem space that my project seeks to tackle. It raises the question; how might...
ABSTRACT As each day passes, new ways of improving our lives through technology emerge. Companies keep on exploring ways of reaching out to their customers and other stakeholders in a way that is more comfortable and efficient. Regardless of their exploration, the problem of presenting information in a way that allows quick retrieval of information by users remains a challenge. To solve the problem of information retrieval, companies have implemented search bars on their website and other fun...
