LLM-Assisted Sensor-Log Fusion for Predictive Maintenance in Nanofabrication Equipment

Predictive maintenance (PdM) is increasingly important for nanofabrication equipment because unexpected equipment faults may cause process interruption, wafer loss, production delay, and increased operational cost. Conventional corrective and preventive maintenance strategies are limited because they either react after...

An O-RAN-Based Resource-Aware Conditional Handover and Local Breakout Architecture for 5G Private Networks with Non-3GPP Access Integration

This paper presents a resource-aware dynamic network selection and Local Breakout (LBO) architecture under the O-RAN framework to fulfill the high-reliability and lowlatency requirements of smart factories. In Industrial 5G Non-Public Networks (NPN), integrating heterogeneous networks (e.g., 5G NR and untrusted Wi-Fi)...

Non-Preemptive Conditional Handover Strategy for High-Reliability LEO Satellite Networks

Resource-Efficient Semantic Retrieval Optimization for Retrieval-Augmented Generation Using FAISS, Milvus, HNSW, and Product Quantization

Retrieval-Augmented Generation (RAG) enhances large language models (LLMs) by integrating external knowledge, but its performance depends heavily on efficient semantic vector search. This paper presents a deployment-oriented empirical study that systematically compares established backends and ANN configurations under...
