Medical imaging has expanded thanks to advances in processing power and advanced image analysis techniques, especially with magnetic resonance imaging (MRI), which offers comprehensive body scans for diagnosis. 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%

This paper describes the application of the development of a biology virtual laboratory which will enable students to conduct practicals as many times as they can with no cost in terms of laboratory apparatus and chemicals required for conducting their biology experiments. 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.

This paper presents the system for Fire Blackbox control in Public Marketing. When information is required following a fire incident, investigators or police might use the smart black box system to collect information. The black box system is used to continuously record, temperature, smoke, and other data. The information is then stored in a storage device. We are able to examine, track, and evaluate fire situations. In this paper, we propose a novel concept termed "Fire Black Box Control" (FBBC) tailored specifically for public marketing spaces. FBBC integrates cutting-edge sensing technologies, data recording, and data analytics. We present a comprehensive framework for implementing FBBC, encompassing sensor deployment strategies, data processing techniques, decision-making algorithms, and performance evaluation methodologies. Through extensive simulations and analysis, we demonstrate the effectiveness of the proposed FBC approach in mitigating fire risks and ensuring regulatory compliance in public marketing spaces

This study investigates the impact of organizational support on integrating communication technology into classroom learning at Kisumu National Polytechnic. In particular, the study aimed at determining the influence of training of trainers, stakeholder involvement, and resource availability on the integration of communication technology in classroom learning. The study employed a quantitative approach and correlational design and sampled 169 of the 301 trainers from KNP for the study. The study utilized a simple random sampling technique to obtain a sample size. A self-administered questionnaire was used to collect data. Descriptive statistics and Pearson correlational analysis were utilized to analyze the collected data. The study found that training of trainers, stakeholders’ involvement, and availability of resources influenced the integration of communication technology in classroom learning with training of trainers and stakeholders’ involvement registering an average mean of above 3.0 and availability of resources registering an average mean of 2.8. At the 5% significant level, the results revealed a strong positive correlation between teacher training (r = .423, p-value = 0.05). stakeholders involvement (r = 0.461*, p-value = 0.02); resource availability and integration of Technology communication in classroom learning (r = 0.347*, p-value = 0.03). The study therefore rejected the null hypothesis as there was an existing strong positive relationship between factors of organizational support and integration of technology communication in classroom learning KNP. The study findings provide vivid insights and recommendations to the management regarding the need to involve stakeholders, train trainers, and avail resources in integrating communication technology in the classroom

Nowadays, Internet-driven culture securing computer networks in Higher Learning Institutions (HLIs) has become a major responsibility. 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

Enterprise resource planning (ERP) systems occupy one of the largest and most important areas of information systems implementation in organisations in the world today. 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).

Soil sustains the life of both animals and plants in the world. Most agriculture activities are conducted in soil. Real-time soil parameter data were collected in three villages of Kyela district (Kisare, Lupaso, and Mabunga) lowland zones during the September 2023 dry season. Observed real-time parameters were soil pH, Electric conductivity, temperature, Nitrogen, Phosphorous, Potassium, and humidity. Soil sensor, multifunctional converter, solar panel, 4G WIFI, and cloud platform (USRIOT) were used. The result shows that nitrogen, potassium, phosphorus, pH, and Electric conductivity have a positive correlation with each other while demonstrating a negative correlation to pH and temperature. Although outliers were observed in real-time nitrogen, phosphorus, potassium, and electric conductivity datasets, they denote a wide variation of such parameters in selected villages. Furthermore, the selected study area demonstrates a relatively low amount of phosphorus compared to other macronutrients

The prevalence of eHealth systems in healthcare facilities has experienced significant growth in many countries. Nevertheless, a significant obstacle that has arisen pertains to the usability of the implemented systems. This paper focuses on assessing the usability metrics that are applicable in evaluating eHealth systems in Tanzania’s contexts. Data were collected through questionnaires and interviews at six health facilities in Tanzania. The main participants were the health workers who were using the eHealth system in their routine healthcare delivery, including pharmacists, laboratory technicians, doctors, and nurses in their different cadres. The analysis of the findings was performed to obtain usability metrics and contextual issues by computing confirmatory factor analysis (CFA) using structural equation modelling (SEM) for quantitative data and thematic analysis for qualitative data. The results revealed that 11 usability metrics constructs with 54 items and 5 contextual issues constructs with 18 items were applicable in evaluating the usability of eHealth systems in Tanzania

This study investigated the impact of computerized systems on public organizations in Iringa Municipality, focusing on the Computerized Accounting System (CAS) and the Government Electronic Payment Gateway (GePG). A mixed research approach and a cross-sectional design were employed, with 100 randomly selected employees from a population of 145 participating through questionnaires and interviews. Data analysis utilized descriptive statistics and multiple regression. The findings revealed that a majority (84.6%) of TRA employees had received training related to computerized systems. Similarly, IRUWASA and TANESCO had a significant portion of trained employees (71.4% and 90.9% respectively). Within IMC and RBWB, 85.7% of employees had attended training, while Mkwawa University and RUWASA showed high training attendance rates at 80%. Concerning network availability, most TRA employees (76.9%) reported inconsistent network availability. This issue was prevalent among IRUWASA and TANESCO employees (63.6% and 90.9% respectively), as well as within IMC and RBWB. The first objective's findings indicated a significant negative impact of system downtime on performance (p-value = 0.000). A one-unit increase in system downtime corresponded to a performance decrease of -0.004. Conversely, training had a positive and significant impact on performance (p-value = 0.013), with a one-unit increase resulting in a performance increase of 0.011. Latency had a significant negative effect (p-value = 0.000), where a one-unit increase in latency led to a performance decrease of -0.039. In light of these findings, it is recommended that public organizations allocate resources for the enhancement and modernization of computerized systems. This should include investments in more robust hardware, software, and network solutions, as well as comprehensive training programs
{"title":"Effect of Computerized Systems on the Organizational Performance: Evidence from Selected Public Organizations from Iringa Municipality","authors":"Neeman Didas Oisso","doi":"10.37284/eajit.6.1.1458","DOIUrl":"https://doi.org/10.37284/eajit.6.1.1458","url":null,"abstract":"This study investigated the impact of computerized systems on public organizations in Iringa Municipality, focusing on the Computerized Accounting System (CAS) and the Government Electronic Payment Gateway (GePG). A mixed research approach and a cross-sectional design were employed, with 100 randomly selected employees from a population of 145 participating through questionnaires and interviews. Data analysis utilized descriptive statistics and multiple regression. The findings revealed that a majority (84.6%) of TRA employees had received training related to computerized systems. Similarly, IRUWASA and TANESCO had a significant portion of trained employees (71.4% and 90.9% respectively). Within IMC and RBWB, 85.7% of employees had attended training, while Mkwawa University and RUWASA showed high training attendance rates at 80%. Concerning network availability, most TRA employees (76.9%) reported inconsistent network availability. This issue was prevalent among IRUWASA and TANESCO employees (63.6% and 90.9% respectively), as well as within IMC and RBWB.
