    Enhanced Named Entity Recognition and Event Extraction for Power Grid Outage Scheduling Using a Universal Information Extraction Framework

    Enhanced Named Entity Recognition and Event Extraction for Power Grid Outage Scheduling Using a Universal Information Extraction Framework by Wei Tang, Yue Zhang, Xun Mao, Mingqi Shan, Kai Lv, Xun Sun, Zhenhuan Ding

    Published 2025-07-01

    To enhance online dispatch decision support capabilities for power grid outage planning, this study proposes a Universal Information Extraction (UIE)-based method for enhanced named entity recognition and event extraction from outage documents. First, a Structured Extraction Language (SEL) framework...

    LDPC-Coded Generalized Frequency Division Multiplexing for Intensity-Modulated Direct-Detection Optical Systems

    LDPC-Coded Generalized Frequency Division Multiplexing for Intensity-Modulated Direct-Detection Optical Systems by Dong Guo, Wei Zhang, Feng Tian, Jianyang Shi, Kaihui Wang, Miao Kong, Junwen Zhang, Kai Lv, Deng'ao Li, Xiaolong Pan, Xiangjun Xin

    Published 2019-01-01

    In this paper, a low-density parity check (LDPC) coded GFDM with high-level modulation scheme is proposed for more flexible and advanced multicarrier modulation in intensity-modulated/direct-detection (IM/DD) optical systems. Then, we experimentally demonstrate an LDPC-coded GF...
