现有的基于电磁感应理论的接地网故障诊断方法需要大量的磁场测量数据,为了解决该问题,笔者提出了一种基于支路影响系数分析的分层诊断方法。首先定义了支路影响系数,并根据影响系数建立了支路诊断难易程度的评价体系。在该评价体系的指导下,分层诊断方法的测量点选取更具针对性,并以分层递进的方式实现了高精确度的腐蚀诊断。在诊断模型求解方面,运用改进的鲸鱼优化算法,保证了分层诊断的准确性。最后,进行了分层诊断与普通磁场反演诊断的对比实验。实验结果表明:分层诊断方法可以在保证诊断准确率的情况下大幅减少测量点数量 ...

Digital Futures Between Participatory Digital Democracy and Participatory Digital Fascism
ABSTRACT This paper explores one of the defining political questions of the twenty‐first century: will digital technologies strengthen democracy or accelerate new forms of authoritarianism and fascism? Against the backdrop of platform capitalism, AI‐driven communication, surveillance infrastructures, disinformation and democratic crisis, the study asks

Multimodal Deep Learning‐Assisted Microstructural Evaluation System for Sintered NdFeB Magnets
ABSTRACT The performance of sintered NdFeB magnets, especially coercivity, is critically determined by their complex microstructure. However, a quantitative microstructural evaluation system (MES) is much needed but has long been missing in the community.

ABSTRACT Disruptive innovations often diffuse faster than inherited policy institutions can classify, assign jurisdiction, and govern them. In these early phases, the central struggle is often not yet about the stringency of substantive standards, but about prior questions of what the innovation is (its legal and administrative classification), who is ...

CT、MRI在眼眶海绵状血管瘤与眼眶神经鞘瘤影像学鉴别诊断中的研究
目的对CT、MRI在眼眶海绵状血管瘤与眼眶神经鞘瘤的影像学鉴别诊断中的应用价值进行研究。方法选取我院2015年3月至2016年3月收治的经CT诊断为眼眶海绵状血管瘤患者38例和眼眶神经鞘瘤患者45例,经MRI诊断为眼眶海绵状血管瘤患者41例和眼眶神经鞘瘤患者39例。对所有患者进行肿瘤鉴别诊断,主要分为定性诊断符合和定位诊断符合,定性诊断符合是影像学诊断与病理诊断结果一致;定位诊断符合是影像学诊断与手术定位结果一致。分别计算CT、MRI的定性、定位诊断符合率。结果 ...
