Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and

基于多频超声波技术和GWO-BP算法的变压器油电气性能检测方法研究
为了实现对变压器油电气性能快速准确地检测,提出了基于多频超声波(MFU)技术和灰狼优化BP神经网络(GWO-BP)的检测方法,利用不同频率超声波在变压器油中传播速度和衰减系数不同、对不同尺寸颗粒物检测效果不同的特点,综合了超声波在无损检测上的优势以及灰狼算法全局寻优能力强、预测精度高的优点。首先利用超声波在非均匀介质中的传播特性,准确地获取超声波在变压器油中的传播速度、衰减系数等特性参数;再利用灰狼算法对传统BP神经网络进行优化。然后利用灰狼优化的神经网络对样本进行训练 ...
