This work proposes a simple yet efficient method to use a support vector machine (SVM) to classify HIV neurocognitive MRI pictures into normal and pathological categories. The model consists of four steps: data pre-processing, feature extraction, SVM classification, and model evaluation. To separate desired and undesired elements, such as the scalp and skull, pre-processed images were converted from grayscale to colour using support vector machines. The discrete wavelet transform (DWT) was used in the feature extraction stage to extract image properties. Colour moments (CMs) were then used to optimize the feature collection. Afterwards, the SVM classifier was used to determine the ideal feature set to classify images. For example, a dataset is used for training and testing, with a split ratio of 75% to 25% respectively. The experimental results show that the proposed model has a high classification accuracy of 94.4%","PeriodicalId":476140,"journal":{"name":"East African journal of information technology","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141668540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of science and technology, which is increasing fast, requires the world of education to improve the quality of education. Visualization and the conduct of laboratory experiments are the most effective ways to simplify and clarify the comprehension of complex theories. Virtual learning environments provide students with the opportunity to get a better understanding. The intention of this project is to develop a biology virtual laboratory for ordinary-level students that improves the learning achievements of students resulting in better performance, especially in many of the government schools where there is inadequate quality biology laboratories. The project aimed at eliminating constraints on traditional laboratories by coming up with a gaming-like android-based application system with visualization of biology practical for ordinary-level secondary schools mainly in food tests and classifications. Students are able to reconduct the experiments until they catch up with no cost of laboratory apparatus by using the game-like developed application.","PeriodicalId":476140,"journal":{"name":"East African journal of information technology","volume":" 29","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141669978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intrusion Detection Systems (IDS) are crucial for protecting networks from unauthorized activity and cyber threats. This paper examines the process of improving network security by creating a comprehensive IDS dataset using real traffic from HLIs, highlighting the importance of accurate and representative data in improving the system's ability to identify and mitigate future cyber-attacks. The IDS model was created using a variety of machine learning (ML) techniques. Metrics like accuracy, precision, recall, and F1-score were used to assess the performance of each model. The dataset used for training and testing was real-world network traffic data obtained from the institution's computer network. The results showed that the developed IDS obtained exceptional accuracy rates, with Random Forest, Gradient Boosting, and XGBoost models all achieving an accuracy of around 93%. Precision and recall values were likewise quite high across all algorithms. Furthermore, the study discovered that data quality has a substantial impact on IDS performance. Proper data preparation, feature engineering, and noise removal were found to be helpful in improving model accuracy and reducing false positives. While the IDS models performed well throughout validation and testing, implementing such systems in a production setting necessitates careful thought. As a result, the essay also examined the procedures for testing and deploying the IDS models in a real-world scenario. It underlined the significance of ongoing monitoring and maintenance in order to keep the model effective in identifying intrusions. The research aids in the progress of network security in HLI. Educational institutions can better protect their precious assets and sensitive information from cyberattacks by understanding the impact of data quality on IDS performance and implementing effective deployment techniques","PeriodicalId":476140,"journal":{"name":"East African journal of information technology","volume":"263 26‐30","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138996970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the role of ERP implementation on Machakos University’s user performance. This study determined the relationship between enterprise resource planning system technology utilisation and user performance, system quality and user performance, and information quality and user performance. This study focused on user performance as compared to most studies that look into performance at the organisational level. The study made use of ICT models of adoption as its guidance. The implementation aspect was viewed from three perspectives, which include system technology utilisation, information quality, and finally, the system quality of the ERP system. Each aspect was analysed, and its effect on ERP system users was established in part and discussed. Data collection involved the use of questionnaires regarding the user performance of the ERP. Pearson’s correlation analysis was the statistical tool analyse the quantitative data. Microsoft Excel was used to capture data and transferred later into SPSS for detailed analysis, while descriptive statistics was used to help understand the characteristics of the study population. Computations from quantitative analysis pointed out respectively that Pearson’s correlation coefficient of technology utilisation = 0.686, system quality = 0.682, information quality = 0.757 and user performance (P-Value = 0.000) under the mediation of technology acceptance. This affirmed that for an ERP system, technology utilisation, system quality, information quality, respectively, and user performance have a statistically significant linear relationship (p < .05). Results also indicated that the magnitude or strength of the association is a strong one for each one of them since each of the aspects had its results within the range (.5 < | r | <.9).
