These data are becoming too large to be maintained on personal storage devices. Technological innovation has cleared the path for vast, remote storage known as the cloud. This innovation is being provided as a service to people and organizations due to the high cost of investment and the high-tech skills needed for its maintenance. Despite the many benefits of cloud computing, data privacy, integrity, and access control are issues that require immediate attention. Many studies have been conducted in order to find solutions to these challenges. In this review, the authors look at the numerous methods that have been proposed to address these security challenges. The research revealed that elliptic curve cryptography and the advance encryption system (AES) were the techniques that were most frequently used to address security issues in the digital world.Item A hyper-heuristic heterogeneous multisensor node scheme for energy efficiency in larger wireless sensor networks using DEEC-Gaussian algorithm(Hindawi Limited, 2021-02-15) Aroba, Oluwasegun Julius; Naicker, Nalindren; Adeliyi, TimothyA wireless sensor network (WSN) is an intellect-sustainable network that comprises multiple spatially distributed sensor nodes and several sink nodes that collect data from sensors. WSNs remain an active research area in the literature due to challenging factors such as the selection of sensor location according to a given premise, finding optimal routing algorithm, and ensuring energy efficiency and consumption. Minimizing energy and prolonging the network lifetime in the WSNs are the focus of this research work. In the literature, a clustering approach is used in grouping sensor nodes into clusters and is seen as an effective technique used in optimizing energy consumption in WSNs. Hence, in this paper, we put forward a novel clustering-based approach by amalgamating the Gaussian elimination method with the Distributed Energy-Efficient Clustering to produce DEEC_Gaussian (DEEC_Gaus) to stabilize energy efficiency optimization in WSNs. We took the advantages of DEEC and Gaussian elimination algorithms to resolve energy efficiency problems in WSNs. DEEC presents attributes such as increased heterogeneity performance level, clustering stability in operation, and energy efficiency which helps to prolong network lifetime while the Gaussian elimination algorithm added an additional advantage to improve and optimize energy efficiency, to aggregate packets of operations performed in the network lifestyle of energy efficiency in WSNs. The simulations were carried out using MATLAB software with 1000 to 1500 nodes. The performance of the proposed work was compared with state-of-the-art algorithms such as DEEC, DDEEC, and EDEEC_E. The simulated results presented show that the proposed DEEC-Gauss outperformed the three other conventional algorithms in terms of network lifetime, first node dead, tenth node dead, alive nodes, and the overall timing of the packets received at the base station. The results showed that the proposed hyper-heuristic heterogeneous multisensor DEEC-Gauss algorithm presented an average percentage of 3.0% improvement for the tenth node dead (TND) and further improvement of 4.8% for the first node dead (FND). When the performance was compared to the state-of-the-art algorithms in larger networks, the overall delivery was greatly improved and optimized.Item An implementation of SAP enterprise resource planning : a case study of the South African revenue services and taxation sectors(Informa UK Limited, 2023) Aroba, Oluwasegun Julius; Abayomi, AbdultaofeekA SAP enterprise resource planning (ERP) is a software system that assists organizations in automating and managing fundamental business processes for ideal performance. This research study aims to ameliorate the business operation problems of the South African Revenue Services (SARS) and Taxation sectors. Involving tax sectors in the preliminary stages of SAP ERP design and implementation saves SARS’ clients some resources such as money and time while also allowing various departments to improve their tax technology ecosystem. To address the associated financial, operational, technical, and compliance challenges, an ERP implementation requiring significant support from strategy execution is suggested. This proposed model for designing and implementing an ERP with a case study of the South African Revenue Services (SARS) and other taxation sectors, the benefits of ERP system within the taxation sector, implementation challenges, and proposed solutions are presented in this article while utilising data from a survey that was conducted for 50 SARS employees and taxpayers outside the organization. The proposed ERP system will enhance the connectivity of all operations within the SARS with a central access to all departments rather than having silos of business operations. From our analysis, the Cronbach report of 0.85 obtained, which is greater than 0.7 minimum, shows that it fits the proposed solution of a SAP ERP mobile app for inclusivity in the operational processes for both SARS employees and other taxpayers.Item Higher education enterprise resource planning system transformation of supply chain management processes(Springer Nature Singapore, 2023) Aroba, Oluwasegun Julius; Chisita, Collence Takaingenhamo; Buthelezi, Ndumiso; Mthethwa, Nompumelelo; Yang, X.; Sherratt, R.S.; Dey, N.; Joshi, A.The goal of this study was to outline the impact of the enterprise resource planning (ERP) system digital transformation of supply chain management (SCM) processes in higher education by using the desk research technique to gather information from other sources that we reviewed to build our study and identify gaps that were detailed in the discussions and results.

It is crucial to analyze stakeholders in these situations and others like them to comprehend their attitudes and expectations toward the system. This experience report discusses problems with a medical institution's regular SAP ERP setup. This report includes insights and suggestions based on traditional system experience regarding a project to adopt SAP ERP at a healthcare facility. It ought to be a beneficial resource for all parties participating in the ERP installation process in the public healthcare sector. Many hospitals struggle to implement system analysis programs (SAP) and enterprise system programs (ERP) to assist in their business processes. The SAP ERP System is an integrated and consolidated way of easily flowing information within the organization's department. The authors identified hospitals' failure to implement a suitable SAP ERP system that works under their operations, leading to inefficiencies in their supply chain management process. This study addresses significant operational issues and productivity of the hospital management processes by administering 50 questionnaires and using Cronbach's alpha to analyze the responses. The Cronbach alpha is considered acceptable if the result is above 0.70. Our Cronbach result is 0.77. The benefits and difficulties of using SAP ERP provide a comprehensive review of the operations of Hospital and Healthcare Centre SAP ERP system digital transformations in supply chain management. Furthermore, the authors developed a framework to assist in choosing the proper tracking and transferring of information within the hospital technology that we named hospitecItem Analysis of road traffic accidents severity using a pruned tree-based model(International Information and Engineering Technology Association, 2023-06-30) Adeliyi, Timothy T.; Oluwadele, Deborah; Igwe, Kevin; Aroba, Oluwasegun JuliusTraffic accidents are becoming a global issue, causing enormous losses in both human and financial resources. According to a World Health Organization assessment, the severity of road accidents affects between 20 and 50 million people each year. This study intends to examine significant factors that contribute to road traffic accident severity. Seven machine learning models namely, Naive Bayes, KNN, Logistic model tree, Decision Tree, Random Tree, and Logistic Regression machine learning models were compared to the J48 pruned tree model to analyze and predict accident severity in the road traffic accident. To compare the effectiveness of the machine learning models, ten well-known performance evaluation metrics were employed. According to the experimental results, the J48 pruned tree model performed more accurately than the other seven machine learning models. According to the analysis, the number of casualties, the number of vehicles involved in the accident, the weather conditions, and the lighting conditions of the road, is the main determinant of road traffic accident severity.Item An ERP SAP implementation case study of the South African Small Medium Enterprise sectors(Step Academic, 2023-06-01) Aroba, Oluwasegun JuliusPurpose – This research examines the enterprise resource planning system (ERP) SAP implementation in SMEs. Small and Medium Enterprises (SMEs) are challenged by their use of manual working style and operations preparations. Human errors in the preparation and execution of important documents such as financial statements, invoices, purchase orders, and internal sales orders have been overcome by business Intelligence processes that computerize every document, efficiently store, Retrieved, and quickly send or receive copies. Methodology – This research proposed solution is an ERP theoretical proposed solution and information evaluation pertinent to the investigation of how to continue and monitor the performance of the ERP SAP procurement process in SMEs. This research technique examines difficulties and suggests solutions. It also includes the stages of the procurement process and the benefit of the enterprise resource planning process, use cases and tables were used to represent the findings generated. Other elements contributing to the ERP procurement process are examined, including the challenges and solutions SMEs face. Furthermore, research on enterprise resource procurement and business intelligence (ERPBI) is conducted to gain in-depth knowledge on how the performance of ERP procurement, including ERP SAP, has been monitored in the existence of SMEs. Findings - ERP implementation and SMEs' outcomes were studied using the explorative approach. To validate the model being created, eight individuals from Business and academia with experience in ERP systems were contacted during the development of the tools. The overall findings offer helpful hints on how organizational and operational elements interact to ensure the successful implementation of ERP. Implementing ERP systems is considered both from the process and organizational learning and knowledge management perspectives. Practical Implications – ERP companies concentrate more on SMEs due to the nearsaturation of ERP adoptions in Large Enterprises (LE). Additionally, many SMEs are implementing ERP systems due to globalization, collaboration, value networks, and the massive information flow between and within SAMEs today. Adoption risks stem from SMEs' limited resources and unique qualities that set them apart from Large Enterprises (LE). This article's primary goal is to highlight the aspect of the ERP in the SME domain that needs further research, suggest future research directions, and give the most recent research findings that could help buyers, suppliers, and SMEs when starting ERP projects. More so, there are advantages to implementing an ERP system successfully. However, there is already evidence of substantial failure risks in ERP implementation projects. The non-technical parts of the implementation project are frequently neglected or given less attention by the project managers, who, instead, concentrate primarily on the technical and financial aspects of the project. Therefore, the study of ERP deployment success is one of the key research topics in ERP systems today. Research Limitations – This study contributes to the knowledge of SMEs' ERP intelligence and procurement process implementation.
