基于传统深度学习模型的接触网绝缘子检测设备,由于模型参数较多,计算量较大,对计算机硬件要求较高,很难安装在轻小型移动端嵌入式平台等设备上。而且运行速度较慢,很难通过视觉对绝缘子清洗机器人进行实时牵引控制。针对这一问题,本研... 基于传统深度学习模型的接触网绝缘子检测设备,由于模型参数较多,计算量较大,对计算机硬件要求较高,很难安装在轻小型移动端嵌入式平台等设备上。而且运行速度较慢,很难通过视觉对绝缘子清洗机器人进行实时牵引控制。针对这一问题,本研究以MobileNet-v1为网络主体对复杂背景下的接触网绝缘子进行特征提取,并以SSD目标检测器对其进行识别。实验结果表明SSD-MobileNet模型大幅度降低了计算量,较大幅度提升了运行速度,但其精度几乎不变,从而实现了模型的轻量化和具备实时性,为绝缘子清洗的开展提供必要的前提。其中,MobileNet是Google推出的一款高效的移动端轻量化网络,其核心即是深度可分离卷积。本研究设计采用基于Pytorch框架来构建SSD-MobileNet模型。 展开更多

Halophilic archaea (haloarchaea) inhabit hypersaline environments,tolerating extreme salinity,low oxygen and nutrient availability,and in some cases,high pH (soda lakes) and irradiation (saltern ponds).Membrane-associated proteins of haloarchaea,such as surface layer (S-layer) proteins,transporters,retinal proteins,and internal organellar membrane proteins including intracellular gas vesicle proteins and those associated with polyhydroxyalkanoate (PHA) granules,contribute greatly to their environmental adaptations.This review focuses on these haloarchaeal cellular and organellar membrane-associated proteins,and provides insight into their physiological significance and biotechnological potential. 展开更多
