Abstract In today’s world, the notion that knowledge has become the most vital resource in the transformational growth of societies is one that is pervasive. The significance of knowledge in modern societies has been overemphasized by several international bodies; most notable the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the World Bank. Ghana's desire to craft an economy where knowledge and information would play a significant role is visible on paper in...
Abstract Machine learning models have gained prevalence in the world we live in today. Currently, they are employed in different fields to automate the decision-making process of various institutions. With the increasing availability of data to train these models, machine learning models are adopted to solve complex classification problems that have the potential to affect people’s lives both positively and negatively. Unfortunately, certain patterns of bias that are tied to the presence of...
Abstract Information sharing through animation is a major step in influencing today’s society to improve their lifestyles for better future. Organizations and government affiliates globally utilize animation in public awareness campaigns to share vital information relevant to societal problems. Interpretation of character movements, gestures and other visual aids vary in cultures but relays pertinent information just the same. This research addressed design issues that affect viewer’s com...
Abstract Cervical cancer is the most common cause of cancer among African women. It is a preventable disease and can be treated if identified at early stages. Given the lack of adequate health care services and the costly nature of colposcopies in Africa, it is difficult to get an early diagnosis. The development of smartphone-based diagnostic tools like MobileODT – with which pictures of the cervix are taken and sent to doctors for diagnosis – promises to address the expensive nature of ...
ABSTRACT Governments all over the world have identified the need to use Information Communications Technology in governance. Electronic governance or E-governance is the use of information and communication technologies in government to provide public services [1]. The use of government portals in E-governance for the dissemination of information and government services is gaining grounds. In Ghana, this practice is not new, in fact there a number of government portals in existence to meet th...
Abstract This paper seeks to discover if using animations to explain computational complexity to Algorithms students is better than using only handouts. As researchers in the field have shown, theoretical topics such as computational complexity are often difficult for students to understand especially because these students find the math and reductions too abstract to understand. In this paper, the author developed a visualisation system with key animations to improve students understanding. ...
Acknowledgement I would first like to thank God Almighty for the strength and wisdom given me to undertake this project. I would also want to thank my family members for their immense support. During times when I felt tired and unable to continue, their words of encouragement kept me going. My special gratitude goes to my supervisor, Dr. Ayorkor Korsah who saw me through from the beginning to the end of my project. During the initial stages of this study when I was confused and uncertain, she...
Abstract Terms Similarity (TS) in retrieval systems are based on lexical matching, which determines if query terms are useful and reflect the users‟ information need in related domains. Existing works on TS use Term Frequency-Inverse Document Frequency (TF-IDF) to determine the occurrence of terms in web documents (snippets) is incapable of capturing the problem of semantic language mismatch. This study was designed to develop a conceptual knowledge model to solve the problem of TS in web ...
ABSTRACT In this research work, a chatbot that will act as a virtual admission officer and make possible student – officer interaction is designed. A knowledge database (KDB) and pattern matching algorithm is used. The algorithm searches through the set of data to find a potential answer to the user’s enquiry and then replies the user or provides a relevant web link if the user is not satisfied with the answer. This reduces the burden on the head of admissions, and potentially other u...
ABSTRACT A huge number of studies have been done supporting seamless mobility networks and mobile technologies over the years. The recent innovations in mobile technologies have unveiled another revolution from the static architectural approach for client-server network relationships to more dynamic, and even mobile approaches. Due to the special equipment and infrastructure needed to support network mobility management, it is difficult to deploy such networks beyond the local network co...
The system developed in this paper uses a cloud based multi-channel technology to implement and design a robust and dynamic cross platform software as a services (SaaS) application for students’ information management system (SIMS). The system runs on a network of infrastructure as a service (IaaS) for the purpose of overcoming the lapses associated with the existing systems developed for managing students’ information. The system was built with the capability to resolve issues on manu...
Secure communication over the Internet has been a global issue till date. Encryption combined with steganography tends to be the best approach to curb the challenge. This paper proposes another approach to further strengthen the existing techniques. The technique involved block encryption of plain text using image as the key and exclusive OR encryption algorithm to produce a cipher. Each bits of the cipher was hidden randomly using modulus function in a selected cover image red and blue pla...
