Zhendong Ceshi yu Zhenduan针对传统一维轴承振动信号特征表达效果较弱、轴承故障数据时频特征提取困难及其诊断精度较低等问题，提出一种基于小波变换与注意力机制网络（wavelet transform and attention mechanism net，简称WTA‑Net）的轻量化轴承故障诊断方法。首先，通过小波变换将滚动轴承的一维振动时序信号转化为二维时频图；其次，针对网络训练时梯度消失的问题，提出改进的轻量化骨干网络R‑ResNet18提取二维时频图特征；然后，在网络不同尺度的特征层嵌入时空注意力机制（convolutional

野生动物学报为有效防治珍稀鸟类误撞输电线路导致的鸟类伤亡与线路跳闸事故，提出一种基于改进YOLOv8模型的鸟类智能识别方法。根据发生撞线事故的鸟类信息及输电线路周边调研结果，构建了包含11种珍稀鸟类的图像数据集，采用加雾加噪操作进行图像增广，用于模拟真实输电线路场景。通过在YOLOv8网络的特征提取部分加入大型分离卷积注意力模块，减少模型参数量，增强模型对于鸟类特征的提取速度；在特征提取和特征融合网络中增加辅助检测头，增强模型对于鸟类特征的学习能力，进而提高检测性能。算例分析表明，改进模型的平均精度均值、F1分数 ...
