ABSTRACT Ghanaian Sign Language (GhSL) is a developing language in the sense that not much is known about it within or outside Ghana. The fact that GhSL is closely-related to American Sign Language (ASL) means that, knowledge of ASL can help one communicate with the Ghanaian Deaf. However, there exist Ghanaian-specific signs that are not available in ASL. This paper presents the Ghanaian Interactive Sign Language (GISL) Tutor, the first computer-based tutor for GhSL designed to teach GhSL voc...
Abstract Transportation has played a vital role in the development of societies globally. The quality of services provided by a country’s transportation sector directly influences the productivity of a country’s citizens. In Ghana, the transportation services offered by public transport agencies are inefficient and unreliable. The lack of transit information about these services often cause a great level of inconvenience before, during and after an intra-city commute. With the development...
ABSTRACT This research work focused on solving Linear Programming Problems with the objective of identifying and reducing the computational complexities or complications involved in solving these problems. In this work, we presented two algorithms; the Standard Simplex method and a newer solution algorithm called Push and Push algorithm. The Simplex method has been one of the oldest and the best methods for efficiently solving Linear Programming (LP) problems until recently. In this work, a m...
ABSTRACT Guaranteed solutions to the current transaction security challenges facing banking industries may not be possible on a large scale, if the solutions are not developed to prevent third party transaction in the used software. Thus, this research lends its voice in support of the move to develop a biometric platform for preventing third party transaction in the banking system. It is meant to use both human face and fingerprint in securing payment platform in the banking software. Hence,...
ABSTRACT Adult literacy is not given much attention in Ghana. This can be clearly seen by the low number of institutions that provide adult literacy programs in Ghana. According to the Ghana Statistical Service, the literacy rate is only about 63.7%. This indicates the gap in literacy that needs to be filled in order to increase the literacy level in Ghana. Although some literacy programs exist, I believe that there must be alternative ways of providing these literacy programs to the citizens...
Abstract The ability to hear is an integral part of being a human being. It plays a vital role in various facets of the human experience, communication, listening to music and even being aware of one’s environment. Unfortunately, not everyone is born with this gift, and the hard of hearing or deaf are thus isolated from society; simply because they cannot communicate and build social connection in the same way as the hearing population. The development of hearing aids was the attempt to bri...
ABSTRACT Classification is the process of finding a set of models that distinguish data classes to predict unknown class label in data mining. The class imbalance problem occurs when standard classifiers are majority-biased while the minority class is ignored. Existing classifiers tend to maximise overall prediction accuracy and minimise error at the expense of the minority class. However, research had shown that misclassification cost of the minority class is higher and should not be ignore...
ABSTRACT Mobile Agent Technology (MAT), remote method invocation and remote procedure calling are the three most widely used techniques for information storage and retrieval in network environments. Previous studies have shown that MAT provides a more efficient and dynamic approach to information storage and retrieval than others. However, for mobile agents to effectively perform their various tasks, a static agent platform must be installed on the computers. These platforms consume more mem...
Abstract The use of electronic devices such as computers and mobile phones have rapidly increased over time. Technological powerhouses have inculcated some form of speech recognition in their devices and as such, the increase in usage of this devices provides the increase in interaction between humans and speech recognition. Speech recognition involves adequately transcribing spoken sentences or words into text. This interaction is present all over the world, Africa inclusively, and the con...
Abstract Ghana needs more innovative thinkers and problem solvers to ensure sustainable growth for years to come. In the past, there have been revisions made to the Ghana educational curriculum to assist in development. Despite these changes, there still exists the predominant issue of rote learning occurring in the classroom. This leads to students being less independent as thinkers and problem solvers. In recent years there have been studies and papers convinced that Robotics education in t...
Abstract Malaria is currently one of the most deadly diseases in the world. While there are different treatment methods for the disease, the search for new drugs against malaria is still a very important area of research. One of the main challenges in manufacturing drugs against malaria is efficiently evaluating the performance of the drugs on the parasites since it requires, amongst others, precise measurements of the parasite growth-stages as well as their counts in blood smear images. The ...
Abstract Businesses in Ghana do communicate with each other through letters, telephones, fax, and emails. Due to the growth of technology, most of these businesses are providing their services online to make it convenient for customers. However, these mediums of communication have some limitations when it comes to language. In the instance where the parties involved in the communication speak and understand different languages, it becomes difficult to understand. Businesses would like to reac...
ABSTRACT Network Threat Management (NTM) is used to model and mitigate network threats classified as major-threats and minor-threats without exceeding Cost of Detection (CD), Time of Detection (TD) and False Positive Rate (FPR) limits. Existing network threat modelling and mitigation frameworks focused on major-threats because until recently, only major-threats are usually harmful, while minor-threats were perceived non-harmful. Recent studies however have shown that some minor-threats are h...
ABSTRACT Spatial qualification problem, an aspect of spatial reasoning, is concerned with the impossibility of knowing an agent‟s presence at a specific location and time. An agent‟s location determines its ability to carry out an action given its known spatial antecedents. There are sparse works on the formalisation of this problem. Qualitative reasoning approach is the most widely used approach for spatial reasoning due to its ability to reason with incomplete knowledge or reduced data...
Abstract Automated machine learning holds a lot of promise to revolutionize and democratize the field of artificial intelligence. Neural architecture search is one of the main components of AutoML and is usually very computationally expensive. Autokeras is a framework that proposes a Bayesian optimization approach to neural architecture search in order to make it more efficient [8]. AutoKeras suffers from two major limitations: (i) the lack of support for parallel Bayesian optimization, which...
