Abstract

The transition toward Industry 4.0 has established predictive maintenance (PdM) as a critical strategy for optimizing operational efficiency and reducing unexpected downtime through real-time sensor data analytics. However, the practical implementation of PdM is frequently hindered by the extreme class imbalance inherent in industrial datasets, where equipment failure events are significantly rarer than normal operating hours. This study presents a comprehensive comparative evaluation of five machine learning algorithms—Random Forest (RF), Decision Tree (DT), Support Vector Machine (SVM), K-Nearest Neighbors (KNN), and Logistic Regression (LR)—utilizing the AI4I 2020 Predictive Maintenance Dataset. By implementing a rigorous preprocessing pipeline that employs Z-score normalization for feature scaling and the Synthetic Minority Over-sampling Technique (SMOTE) to mitigate majority-class bias within the training partition. The models were evaluated on a hold-out test set of 2,000 instances using metrics including accuracy, precision, recall, and the F1-score. Results indicate a pronounced “Accuracy Paradox” in linear and distance-based models; while KNN and Logistic Regression achieved deceptively high accuracies exceeding 96%, they failed to reliably detect actual failure signatures. In contrast, Random Forest emerged as the superior architecture, achieving an F1-score of 97.10% and a recall of 98.53%, correctly identifying 67 out of 68 failure instances. This research concludes that F1-score and Recall are more vital indicators of industrial reliability than simple accuracy. The findings provide a standardized framework for selecting ensemble-based classifiers to support scalable, data-driven maintenance strategies in modern smart manufacturing environments.

Abstract

In modern wireless networks, efficient handoff strategies are crucial for several services with various Quality of Service (QoS) requirements. However, a significant research gap exists as most current handoff techniques treat all internet traffic uniformly, leading to performance degradation, latency, and glitches for time-sensitive applications like Ultra-Reliable Low Latency Communication (URLLC) during network transitions. To address this, the main objective of this study was to develop the Multi-Level Handoff Prioritization (MLHP) framework specifically for buffered handoff setups. The MLHP system integrates three core components: a multi-level service classifier, a dedicated buffering architecture with dynamic thresholds, and a hybrid scheduling mechanism combining Strict Priority and Weighted Fair Queuing. Simulation results reveal that MLHP significantly outperforms both traditional Non-Prioritized Buffered Handoff (NPBH) and Dynamic Queue Management (DQM) schemes. Key findings indicate that MLHP maintains a low dropping probability of approximately 6% under high handoff frequencies and achieves an aggregate throughput exceeding 44 Mbps during high mobility scenarios, while successfully maintaining sub-10 ms delays specifically for mission-critical URLLC traffic. The broader implications of this study suggest that MLHP provides a scalable and flexible solution for handoff management, effectively meeting the stringent requirements of 5G-and-beyond networks. By ensuring granular service differentiation, the framework enhances overall network reliability and user experience in increasingly heterogeneous mobile environments.

Abstract

The two most important factors for location-based mobile navigation services are navigation performance and trusted data governance, especially when location data is used repeatedly. Previous studies have tended to focus on privacy concerns, perceived risk, trust, transparency, control, and service quality separately or in settings other than consumer navigation, as is the case in this study. As a result, the interaction between privacy risk perceptions and provider assurances in influencing mobile navigation acceptance remains poorly defined. This conceptual study develops a trust- and privacy-based user acceptance framework by synthesizing the literature through a structured procedure and incorporating the Technology Acceptance Model, Privacy Calculus Theory, and Trust Theory. The framework posits that privacy concern increases perceived risk, while privacy concern and perceived risk reduce trust. In contrast, transparency, perceived control over location data, and service reliability can enhance trust. The roles of perceived usefulness and user acceptance intention in the pathway to user acceptance remain unchanged, suggesting that trust is an antecedent to perceived usefulness and user acceptance intention. The framework fills the theoretical gap between privacy-risk assessment and trust-building service attributes, and between trust in technology acceptance and repeated disclosure of the location setting. It also recognizes the need for transparent data practices, meaningful location control, and reliable service performance as provisional design priorities, which require future empirical validation. The propositions are to be used as a starting point for further testing on platforms, providers, user groups, cultures, and regulatory frameworks.
