Gaoya dianqi, 2021 对GIS的振动信号进行分析可以及时有效的发现设备中存在的故障。在GIS设备的故障诊断中,特征提取是最为关键的步骤,文中针对单一种类的特征提取方法提取到的特征容易缺乏特异性这一缺点,提出了基于复合特征的GIS振动信号特征提取方法。首先将奇异值分解和基于总体最小二乘准则的旋转不变技术这两种时频法结合起来对振动信号中具有明确物理意义的特征量进行提取,对于没有明确物理意义的特征量,通过数据序列法中的变分模态分解和多重分形来对其进行提取;然后将这两种特征量组合得到新的特征量 ...

World Medical &Health Policy, Volume 18, Issue 3, September 2026.ABSTRACT This study examines the association between catastrophic health expenditure (CHE) and distress financing among India's uninsured “missing middle,” a population largely excluded from public insurance schemes and private coverage. While healthcare‐induced financial hardship is well documented, evidence on subsequent coping strategies among this ...

, 2016 近年来，使用微藻生产食用油脂进入了人们的视野。微藻油脂以甘油三酯为主，脂肪酸组成与植物油类似，有些还含有极具健康价值的多不饱和脂肪酸。本文考察了几种常见富油微藻生产食用油脂的潜力，并以微拟球藻藻粉为原料，建立了富含多不饱和脂肪酸的微藻油脂提取和精炼工艺。考察了小球藻、栅藻和微拟球藻油脂和藻渣应用于生产食用油的前景。使用适用于食用油生产的正己烷获得微藻油脂，小球藻和微拟球藻油脂收率均在50%左右，是栅藻的两倍，且小球藻藻油的中性脂含量最高；三种藻油脂的中性脂脂肪酸组成均以C16和18脂肪酸为主 ...

Gaoya dianqi, 2009 憎水性图像水珠形状提取是绝缘子憎水性等级评价的重要前提。Snake模型在提取边界轮廓时存在着对初始轮廓敏感、边界信息捕捉能力较差等问题,为此笔者在S-L模型的基础上,利用水珠图像的先验信息来改进S-L模型对水珠形状的提取过程,在一定程度上克服了Snake模型的缺点,提高了轮廓形变过程中的拓扑能力,提高了形状提取的精确度。实验结果表明,该方法有效地实现了水珠形状的提取,为后续绝缘子性能的等级评价提供依据。
