Geomagnetic Variations Associated with Strong Earthquakes in Yunnan Area

Open Journal of Earthquake Research 2017年第4期6卷 228-237页

作者： Xiuyi Yao Zhisheng Feng Yuntian Teng yunhui Wang Qiuyue zheng Yunnan Earthquake Agency Kunming China Jiangsu Earthquake Agency Nanjing China Institute of Geophysics China Earthquake Administration Beijing China

In order to find geomagnetic anomalies associated with Ms ≥ 6.0 strong earthquakes in Yunnan area, geomagnetic harmonic wave amplitude ratios with Z, H and D components in TCH, THJ, CHX and YOS stations were analyzed. It was found that geomagnetic amplitude ratio of Yzhx experienced a trend of decrease and increase before most of strong earthquakes. Moreover, these variations in different periods were inconsistent and no similar changes appeared for Yzhy, which may relate to fault-zone conductivity variation and seismogenic structure.

航空发动机剩余寿命(remaining useful life,RUL)预测是设备故障预测与健康管理(prognostics and health management,PHM)的核心问题。针对发动机数据维度高、滞后性强和复杂度高等挑战,提出了一种基于自训练权重的多尺度注意力双向长短期记忆神经网络模型。通过不同尺度的双向长短期记忆神经网络(bidirectional long short-term memory neural network,BiLSTM)提取多尺度特征;提出一种基于自训练权重的融合算法,通过引入注意力机制进行不同尺度的特征筛选,以提高预测精度。将各模型在NASA的C-MAPSS数据集上进行实验对比,结果证明,所提出预测模型在准确率和均方根误差指标上均有所提升。
