Natural Language Processing is a flourishing aspect of Data Science in both academia and industry. This paper examines the technique of sentiment classification on text data using automated Machine learning approaches. It will delve into newly introduced embedding techniques and machine learning model pipelines. The models explored in this paper consist of a simple Naive Bayes classifier, as well as several Deep Neural Models, including a Gated Recurrent Unit (GRU) and a Long Term Short Te...
An investigation was carried out to identify the different types of polymers used in paint and surface coatings and variations of the final products upon modifications of the materials used. The process of manufacturing paint and surface coatings involves a great deal of understanding various molecular behavior of paint and surface coatings polymeric matrix. These advance knowledge helps in developing new and advanced modifications of the super polymers. Every desire of a paint and surface co...
ABSTRACT Electronic Health Record systems (EHR) are increasingly being deployed within healthcare institutions to reduce the problems and limitations of the paper-based approach but its deployment has been slow due to high investment and maintenance cost. Cloud Computing has been widely recognized as the next generation’s computing infrastructure and it offers several advantages to its users. In this study, an Enterprise Electronic Cloud-Based Health Record System (E2CHRS) was designed, i...
The study examined the influence of e-learning facilities on academic performance of business education students in Federal College of Education (Technical) Asaba, Delta State. The study was guided by four research questions and was examined. Extant related literature on influence of e-learning facilities on students’ academic performance were diligently carried out on each of the concepts and variables of the study. The study was anchored on a constructive learning theoretical basis that e...
Abstract This study includes phytochemical screening, quantification of secondary metabolites, thin-layer chromatography (TLC) and antimicrobial assay of African peach (Sarcocephalus latifolius). The phytochemical analysis revealed the presence of alkaloid, flavonoid and saponin at various quantities with saponin more abundant amongst others like tannin, glycoside and phenols that are present. All the extracts were tested for antimicrobial activity with ethanol extract and water extract...
Steganography is important due to the exponential development and the secret communication of computer users over the internet. Steganography is a data hiding technique, which is used to hide the data within a file to avoid detection. Stenography or covered writing is of hiding private or sensitive information which appears to be unrevealed information. Hiding information or wrapping information in other information like image, audio, video etc. KEYWORDS:Steganography,Data concealing,Sec...
ABSTRACT This study investigates the decolourization of reactive blue 4 textile dye solution by heat activated persulfate. Synthetic textile dyes have been found to be non-biodegradable, toxic and carcinogenic and thus potentially harmful to both the environment and living organisms when improperly discharged to the environment. A lot of attention have been given to Azo dyes which make up approximately 60% of the reactive dyes with limited study conducted on other classes of reactive dyes suc...
ABSTRACT Assistive technologies to aid the visually impaired have evolved over time from screenreading software, magnification programs and daisy book readers, there are a plethora of devices to aid the visually impaired in their daily activities. Despite the established utility of such devices they face certain limitations that have hindered their widespread adoption, such as cost, stigma attached to using the product in public, and lack of continued support for the product. In this time sm...
ABSTRACT The proposed system is a dynamic model of social media monitoring tool with sentiment analysis. Social media platforms contain a lot of data which might be considered ambiguous to businesses/organizations. Most organizations make use of social media platforms for advertisement as they reach a large crowd in a short period of time and are also more affordable compared to other options. Businesses find it difficult to have a clear vision/insight on how well their business has grown af...
ABSTRACT In this Thesis, The Personal Services Locator helps users to find personalized workers or “Handymen” as fast as possible. The issue of finding a person or an individual to do a certain job has always been around, even though it has been reduced with the use of adverts and various social media, it’s not as fast and as efficient at locating people. This application finds the closest person(s) with the services running depending on which personalized service the user is looking f...

The proposed thesis is designed to be an online Baze University past question archiving system. The use of technologies has become critically important in the era of the Coronavirus pandemic which has required off-campus distance learning by students of Baze university. With no access to staff and on-campus facilities, the availability of easily accessible online study material has become critical. This project aims to provide students with the necessary materials needed to aid with learning ...
Pulmonary Tuberculosis (PTB) is a major public health problem in Nigeria. It was declared a national emergency in 2006 after which an emergency plan for the control of TB in Nigeria was developed. The country is currently ranked 10th among the 22 high TB burden countries in the world. Tuberculosis is an important opportunistic infection in HIV/AIDS. Benue state is the highest HIV endemic state in Nigeria and investigation of tuberculosis cases and Mycobacterial resistance patterns are needed....
An average Nigerian household consumes vegetables of various kinds but are ignorant of their antibacterial properties and other benefits. There is also an increase in the prevalence of multidrug resistant strains of bacteria which has raised the spectra of untreatable bacterial infections. This challenge has requested for urgency to search for new infection-fighting strategies. This study therefore investigated the antibacterial activities of the ethanolic and acetonic leaf extracts of Solane...
