Policies and reporting guidelines for small biopsy specimens of mediastinal masses [PDF]
, 2014 目前，胸腺恶性肿瘤治疗方案大多是根据术\ud 后病理确定，然而，多数临床治疗决策需要在术前\ud 通过活检小标本的病理报告来制定。所以，术前活\ud 检小标本的正确获取和病理解读对治疗决策的制定\ud 显得非常重要[1]。这些标本包括细针活检标本，带\ud 芯穿刺活检标本和手术切取活检标本[2-7]。由于胸\ud 腺肿瘤的病理诊断对组织的获取方法和获取量都有较高\ud 的要求，加之对病理的描述也没有统一的标准，使得小\ud 标本在诊断胸腺瘤方面存在诸多问题。为此，ITMIG在\ud ...

Dianci bileiqi, 2021 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 ...

Research on Improvement and Applications for Bayesian Fault Diagnosis [PDF]
, 2016 控制回路故障检测与诊断有助于保证生产过程的安全和高效、降低维护费用和减少停机时间。贝叶斯诊断是控制回路监测的概率化诊断框架，它能够综合多个监测器技术，以构建诊断系统进而作出最优决策。然而，工业过程控制回路诊断中存在许多不同的实际情况，严重制约了贝叶斯诊断的性能。本文重点从数据降维、似然估计等方面研究改进贝叶斯诊断性能的方法，提出了基于优化直方图估计的证据离散化方法、基于线性判别分析的特征提取与降维以及平均移动似然估计方法。通过仿真系统、工业基准数据和工业规模系统的仿真实验，验证了所提方法的有效性 ...
