Abstract

OFDM is a promising technology due to its robustness against multipath fading. Multipath fading distorts a signal propagating in free space due to destructive or constructive interference. The evolution of 5G wireless networks has necessitated the integration of high-throughput, low-latency multi-band modulation schemes, such as orthogonal frequency division multiplexing (OFDM), into real-time hardware-optimized platforms. However, challenges related to spectral efficiency, security, and the maximum-to-average power ratio (PAPR) remain, especially when these schemes are implemented on field-programmable gate arrays (FPGAs). Steganography offers increased information security. Therefore, this paper proposes an improved OFDM model for 5G that incorporates advanced data hiding techniques using steganography to embed secure image data within ORFDM subcarriers. The proposed system is implemented on an FPGA platform, leveraging high-speed pipelines and parallelism to achieve real-time performance at a minimal resource cost. Simulation and synthesis results demonstrate significant improvements in reduced PAPR, BER, and device efficiency compared to conventional OFDM applications. The FPGA platform design takes up approximately 20% of the total available space, with very low energy consumption compared to other traditional implementation methods. The results also showed an improvement in the OFDM system's performance by reducing the BER by 30%, indicating the absence of data loss and the effectiveness of the steganography technique in these systems. This results in improved architecture performance in terms of area, power, and speed. Furthermore, the proposed approach has proven its worth in terms of security and permeability.

Abstract

The prevalence of misinformation in digital media highlights the need for effective fake news detection methods. This paper presents a novel approach that leverages domain-specific word embeddings, trained specifically on news content, to improve the accuracy of fake news classification. Using TorchText, we generated 128-dimensional embeddings, optimized with Bi-LSTM and GRU models, achieving a test accuracy of 93.51% with a margin of error of 0.255. Two models were developed to classify fake news based on news headlines. The first model using pre-trained embeddings achieved a test accuracy of 96.51% with a margin of error of 0.102, and the second model trained without pre-trained embeddings, resulting in slightly worse resulting in a slightly lower accuracy of 96.23% with a loss of 0.104. The comparison highlights the significant impact of domain-specific integration on model performance. This study demonstrates the value of custom integration to improve semantic representation and fake news detection accuracy, providing a powerful tool to combat misinformation.

Abstract

Cloud Computing has the benefit of offering on-demand scalable services to its customers without having to invest much on hardware infrastructure, resources and software. Most private and public sectors are moving to the Cloud. As a result, Cloud Computing has become an ideal option due to its flexibility, scalability and cost efficiency. The existence of vulnerabilities in the network systems hosting Cloud have raised an opportunity for attackers to launch attacks in Cloud Computing. The intruders attack business applications such as webservers, financial servers, and other servers exploiting Distributed Denial of Service (DDoS) attacks. This paper proposed a Real-Time Network Traffic Attack Detection (RTNTAD) algorithm to detect DDoS attacks using real-time dataset to mitigate DDoS attacks. MATLAB was employed to evaluate the performance of RTNTAD. The proposed RTNTAD algorithm has achieved 99.2% detection rate, 99.5% classification of DDoS attacks, 0.9% connectivity time out and less than 18% false positive.

Abstract

Electricity consumption continues to increase year by year, leading to inefficiencies in energy management. This issue has become a major concern in modern power systems, particularly in energy monitoring systems based on Smart Grid technology. As the use of technology becomes more accessible, energy loads also grow significantly. Therefore, the ability to identify the types of electrical loads used in an installation is crucial, necessitating the implementation of load classification systems. To support the performance of electrical load classification, a Feed-Forward Neural Network (FFNN) is utilized. The results of this study show that the classification model achieved an accuracy of 99.03% with an error rate of 6.43%, and the RSME 0.098, indicating excellent classification performance

Abstract

Academic fraud, particularly the falsification of qualifications, poses a growing threat to organizational integrity and professional credibility. This study proposes an Information Verification System (IVS) to combat employee credential fraud using a hybrid of Artificial Neural Network (ANN) and Random Forest (RF) algorithms. The method follows a two-step process: first, ANN extracts key certificate features, such as digital signatures, logos, and serial numbers, then RF classifies the certificate as authentic or fraudulent based on these features. Tested on 4,830 certificates from Mopani TVET College, alongside 1500 replicas, the system achieved near-perfect results: 98.90% accuracy, 96.75% precision, 99.33% recall, and a 98.03% F1-score, outperforming Recurrent Neural Networks (RNN), Support Vector Machines (SVM), and Logistic Regression models. By integrating with institutional databases, the IVS offers a scalable, secure solution to automate verification processes so that only legitimate qualifications are accepted. These results suggest that the proposed IVS offers a scalable and secure solution for institutions and employers, significantly improving the efficiency and reliability of academic credential verification.

Abstract

India's railway station network is a vast and complex system that plays a crucial role in the country's transportation infrastructure. In this analysis, we will explore the network of Indian railway stations using network analysis techniques. Network analysis is a statistical approach to analyzing the relationships between variables in a network. A network is a graphical representation of the relationships (edges) between variables (nodes). The study will involve constructing a network representation of the railway station network, where each station is represented as a node, and the connections between stations are represented as edges. This visualization allows us to identify the type of network, communities, overlapping communities, cascade failure, and heterogeneous information network within the network. Based on the analysis results, the formed network is a scale-free network. The community detection analysis using the Leiden algorithm shows that there are 23 clusters formed with a quality value of 0.97662. Overlapping communities are present when the value of K ≤ 3, and there is the potential for cascade failure or an epidemic when the node with the highest degree is assigned the status of infected. The formed India's railway station network is a HINs (heterogeneous information network) as it consists of various types of entities with different characteristics.

Abstract

Cybersecurity has become a major challenge for financial institutions, including PT. XYZ. Although PT. XYZ has established a Security Operations Center (SOC) to safeguard its digital assets, the current SOC team lacks optimal capability to monitor the organization's newly adopted public cloud environment. This gap increases the risk of undetected cyberattacks targeting the cloud infrastructure. This study aims to develop recommendations for enhancing SOC capabilities in PT. XYZ’s public cloud environment using the Design Science Research (DSR) method. The initial SOC condition was analyzed through document review and observation. Capability gaps were identified through focus group discussions (FGD) guided by the SOC-CMM screening tool. The NIST Cybersecurity Framework (CSF) was then employed as the foundation for defining target capabilities. The study resulted in a set of 35 practical recommendations to improve the SOC team's capabilities, categorized according to the SOC-CMM domains.

Abstract

Diabetes mellitus is a growing public health issue in Malaysia, affecting 7 million adults aged 18 and older. By 2025, 20.1% of Malaysians will have diabetes, with the International Diabetes Federation predicting 5 million by 2030. A study aims to improve diabetes prediction accuracy and reliability. The Indian PIMA Diabetes dataset was used to develop stacked machine learning and deep learning models, with 70% ML and 30% DL achieving optimal results. The weighted soft voting ensemble (70% ML, 30% DL) outperformed individual stacking models in terms of reliability and balanced performance, improving diabetes classification with 75.65% accuracy, 67.89% precision, and 81.41% ROC-AUC. The ensemble method, optimized for medical diagnosis tasks, showed improved accuracy, robustness, and generalization. However, ethical considerations, data privacy, and algorithmic biases are crucial for maximizing AI's potential in diabetes care, highlighting the need for scalable solutions.
