This paper proposes a robust sparse-aware maximum correntropy criterion (SA-MCC) algorithm for channel estimation in RIS-assisted hybrid MIMO mmWave systems, demonstrating superior performance over conventional methods in the presence of impulsive noise and hardware impairments.
This paper presents a scenario-based system safety engineering approach that analyzes 80 publicly documented maritime autonomous surface system scenarios to develop a hazard taxonomy, control-loss pathway model, and specific recovery-oriented safety requirements, demonstrating that safe operation depends more on explicitly defined degraded modes and fallback behaviors than on autonomy levels alone.
This study analyzes 80 documented BESS failure incidents to propose a comprehensive fire safety engineering framework that addresses the interplay of barrier degradation, emergency response constraints, and community exposure, ultimately advocating for enhanced design and operational safety requirements.
This paper presents a theoretical grinding force model for helical gear form grinding that incorporates spatial geometric and kinematic characteristics, which was experimentally validated to reveal how process parameters and tooth profile positions influence force distribution and variation.
This paper proposes CorrGreedy, a lightweight, correlation-aware user grouping heuristic that refines group assignments based on normalized pairwise channel correlations to improve matrix conditioning and achieve competitive spectral and energy efficiency for zero-forcing precoding in spatially correlated massive MIMO downlink systems.
This paper presents a novel fully coupled Electro-Thermo-Magneto-Mechanical-Hydrodynamic (ETMMHD) finite element model, validated against experimental data on DP600 steel, which significantly improves the prediction of molten zone evolution and expulsion phenomena in resistance spot welding by incorporating fluid flow dynamics neglected in classical models.
This paper presents a reproducible, open-data geospatial workflow implemented in QGIS to assess coastal electrical infrastructure exposure to flood and coastal hazards, demonstrating its effectiveness through contrasting applications in Jamaica and Mozambique that reveal distinct vulnerability patterns driven by their respective island and deltaic geographies.
This paper presents a low-cost, high-reliability IoT system for preventing newborn theft in hospitals, utilizing a multi-criteria architecture that combines RFID and GPS with convex hull modeling and an A* algorithm to achieve 100% detection of critical threats and zero false positives across 18 simulation scenarios.
This paper proposes a fast detection method for AC short-circuit faults in shipboard power systems using a decoupled double synchronous rotating frame (DDSRF) to precisely separate voltage sequences and construct a fault state variable, achieving detection times under 2 ms with over 50% improvement in speed compared to traditional RMS methods.
This paper proposes and verifies an Optimized Carry Select Adder that integrates Speculative Logic with Kogge-Stone prefixing to significantly reduce computation time and hardware resource utilization for high-speed, low-power VLSI applications.
