The heightened frequency and ferocity of recent security breaches and electronic document falsification pose significant concerns globally. These incidents underscore the critical need for robust security measures to protect sensitive documents from unauthorized access and tampering. While digital signatures are essential for ensuring the authenticity and integrity of electronic documents, traditional digital signature algorithms can be computationally intensive, making them unsuitable for resource-constrained environments such as IoT devices and mobile applications. This paper explores lightweight digital signature algorithms that offer robust security with minimal resource consumption. We investigate, implement, and evaluate the performance evaluation of lightweight digital signatures, highlighting their efficiency in both signature generation and verification processes. Our findings demonstrate that these algorithms can significantly enhance the security of electronic documents without compromising performance. © 2024 IEEE.

Globally, Information Communication Technology (ICT) device usage has seen a steep rise over the last few years. This also holds in developing countries, which have embarked on connecting the unconnected or previously disadvantaged parts of their populations. This connectivity enables people to interact with cyberspace, which brings opportunities and challenges. Opportunities such as the ability to conduct business online, attend online education, and perform online banking activities. Challenges experienced are the cost of Internet access and more worrying cyber-risks and potential for exploitation. There remain pockets of communities that experience sporadic connectivity to cyberspace, these communities tend to be more susceptible to cyber-attacks due to issues of lack/limited awareness of cyber secure practices, an existent culture that might be exploited by cybercriminals, and overall, a lackluster approach to their cyber-hygiene. We present a qualitative study conducted in rural Northern Namibia. Our findings indicate that both secure and insecure cybersecurity practices exist. However, through the Ubuntu and Uushiindaism Afrocentric lenses, practices such as sharing mobile devices without passwords among the community mirror community unity. Practices such as this in mainstream research can be considered insecure. We also propose interrogating 'common' secure cybersecurity practices in their universality of applicability. © 2023 IEEE.

Finding the inverse z-transform of a rational function is usually considered a completely routine task with nothing special to say about it. However, practically all the procedures described in the engineering literature for doing this task can be very laborious for manual calculation when the function whose inverse z-transform is sought has multiple poles. This is often a problem for students when solving homework and exam tasks. The situation is particularly awkward when the poles are ugly numbers. Additionally, the described procedures are very unsuitable for programming on a computer. This paper proposes a simple, elegant and student-friendly way to calculate the inverse z-transform of a rational function. In addition to the basic variant, which is most suitable for manual calculation when the poles are relatively nice numbers, there are also variants that may be more suitable in other cases, including a variant that is extremely suitable for programming on a computer, even on the programmable calculators. © 2023 IEEE.

In secondary schools, traditional chemistry instruction often depends on lecture-based approaches and occasional hands-on experiments, which may limit students' grasp of complex concepts like chemical reactions and molecular behaviour. This study addresses the need for enhanced educational tools by introducing a Virtual Reality (VR) application designed to enrich chemistry learning through immersive, interactive experiences. The VR tool allows students to simulate chemical reactions with adjustable parameters, such as temperature and concentration, enabling safe, hands-on exploration of complex processes. Usability was assessed among 30 secondary school students in Malaysia using the System Usability Scale (SUS), a standardized measure that gauges user experience across factors like functionality and ease of use. Findings showed a strong average SUS score of 91.25, indicating high usability and positive engagement from users. These results suggest that incorporating VR into the chemistry curriculum can help make challenging topics more accessible and engaging, supporting the modernization of science education. Future studies will look to expand the sample size and investigate additional chemistry topics to validate the tool's educational benefits further. © 2024 IEEE.

Providing excellent customer service is always important for an organisation, and one of the biggest demands from customers is the speed of resolution. Customers anticipate a prompt, simple, and efficient response when they submit a service ticket to request service. While the customer service representatives attempt to resolve problems assigned to them while simultaneously giving clients a nice experience and upholding the company's excellent reputation, they receive several tickets each day. On-time services may boost customer satisfaction, foster client loyalty, and grow the number of prospective loyal consumers. The best option for speeding up ticket resolution in this case will be a prediction model that makes use of Machine Learning techniques. Experimental evaluations revealed that eXtreme Gradient Boosting works better than other strategies by achieving a low Root Mean Squared Error (RMSE), Mean Squared Error (MSE), and MAE (Mean Absolute Error) scores with good model accuracy. © 2023 IEEE.

Hand, foot, and mouth disease (HFMD) is consistently present in Malaysia, with a rising number of reported cases. Sabah has encountered multiple outbreaks of this disease. However, detailed information regarding the epidemiology and molecular traits of the viruses responsible for these outbreaks remains limited. This study used two data sets;one dataset was acquired from ***, containing HFMD across various Malaysian states. The second dataset was sourced from the National Center for Biotechnology Information (NCBI) and consists of HFMD statistics for Malaysia, including case counts and weather data. Both datasets were merged to create a comprehensive dataset that was specifically focused on examining the Malaysian state of Sarawak. This consolidated dataset contains a total of 20 at-tributes, forming the basis for the subsequent analyses conducted in this study. The study employed four distinct machine learning methods for regression analysis, comprising Random Forest, XGBoost, Decision Tree, and LASSO regression. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder with an increasing prevalence among the elderly, making early and accurate diagnosis critical for effective intervention and management. This paper introduces an end-to-end machine learning pipeline optimized for detecting AD using multimodal data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI). The study proposes an ensemble model that integrates key modalities—demographics, cognitive scores, neuropsychological assessments, and MRI data—via early fusion to enhance AD detection. Various machine learning models, including Logistic Regression, Gradient Boosting, AdaBoost, XGBoost, Support Vector Machine, and Neural Networks, are compared, and feature selection is optimized through Recursive Feature Elimination, ANOVA F-value, and mutual information methods, with mutual information showing the most efficacy. With further hyperparameter tuning, the highest accuracy is achieved at 95.85%, with Gradient Boosting as the top-performing model. Additional experiments assess and evaluate individual modality contributions, underscoring the predictive value of cognitive scores and neuropsychological features. To enhance clinical interpretability, we incorporate model explainability using LIME and SHAP, which identify key features influencing model predictions across different AD stages. Explainable AI (XAI) is essential in healthcare for providing transparency and supporting clinician confidence by highlighting which biomarkers, such as MMSE, CDRSB, and PTAU, contribute most to diagnostic outcomes. This study demonstrates classical machine learning's potential in AD diagnostics, offering a pathway to cost-effective and clinically viable models for neurodegenerative disease management. © 2025 IEEE.

The manual analysis of job resumes poses specific challenges, including the time-intensive process and the high likelihood of human error, emphasizing the need for automation in content-based recommendations. Recent advancements in deep learning, particularly Convolutional Neural Networks (CNN) for Multi-label Text Classification (MLTC), offer a promising solution for addressing these challenges through artificial intelligence. While CNN is renowned for its robust feature extraction capabilities, it faces specific challenges such as managing high-dimensional data and poor data interpretability. To address these limitations, this study employs the Fuzzy Discernibility Matrix (FDM) feature selection technique to determine the relevance of skills for each job vacancy. FDM assigns weights to the features of each job category and ranks their relevance based on the highest scores, which are then utilized in the MLTC CNN model. The integration of FDM and MLTC CNN serves as the foundation for generating content-based recommendations derived from key features in job resumes. This study produces a content-based job recommendation system that displays the top three job categories, accompanied by explanations of the skills supporting each selected category. These recommendations also consider cosine similarity values between analyzed items and the integrated results of FDM and MLTC CNN. The application of FDM for feature weighting has been proven to enhance multi-label text classification outcomes by providing better insights during the feature selection process. With a recall of 97.26%, precision of 94.81%, and accuracy of 98.58%, the MLTC model integrating FDM feature selection and CNN demonstrates robust performance characteristics in content-based job recommendation tasks. © 2025 Slovene Society Informatika.

Melon Manis Terengganu (MMT) is of significant cultural and economic importance to the people of Terengganu and Malaysia as a whole. The demand for melon fruit is also increasing year by year. However, one of the challenges in producing a quality melon is the soil condition. The soil condition must be good to ensure that the melon can get enough water and fertilizer. The objective of this research is to develop a formulation and implement IoT technology to monitor the process of melon growth by analyzing data related to soil conditions. The purpose of Internet of Things (IoT) is to capture data using sensors and send it to a database system. In this method, a formulation is designed to calculate the amount of water and fertilizer based on soil moisture, soil electrical conductivity (EC), NPK levels, pH level, and water electrical conductivity (EC). These sensors will capture the data and send it to a database system. After that, the system will calculate the actual amount of water and fertilizer needed for each melon plant. This approach will help farmers supply the correct water and fertilizer levels for each melon plant. The implementation of IoT technology in agriculture, especially for melons, is expected to promote smooth growth and the production of high-quality melons. © 2024 IEEE.
