基于LFPCDA的转子故障数据集降维算法

open access: yesZhendong Ceshi yu Zhenduan
针对旋转机械高维故障数据集中特征属性冗余导致的故障分类困难问题,提出一种基于局部Fisher主成分判别分析(local Fisher principal component discriminant analysis, 简称LFPCDA)的故障数据集降维算法。首先,利用Laplacian得分算法过滤高维故障特征集中冗余特征,并将主成分计算融入局部Fisher判别分析(local Fisher discriminant analysis, 简称LFDA)中 ...

细胞密度与表观弥散系数的相关性探讨

open access: yesZhongguo shiyan zhenduanxue, 2006
目的研究乳腺磁共振成像(Magnetic resonance imaging,MRI)弥散加权像(diffusion-weighted image,DWI)中表观弥散系数(apparent diffusion coefficient,ADC)的影响因素。方法对照病理分析32例乳腺疾病患者的42个ADC值异常的感兴趣区,分析ADC的相关影响因素。结果乳腺间质成分百分比与ADC值呈正比趋势,随间质百分比的增加ADC值增加。肿瘤组织内出血、坏死及间质成分中纤维细胞排列的疏密对ADC有明显影响 ...

Interest Rate Policy, Investor Sentiment and Stock Market [PDF]

open access: yes, 2016
中国人民银行自2015年以来进行了5次降息,同时还决定对商业银行与农村合作金融机构等不再设置存款利率浮动的上限,这就意味着我国利率市场化已经进入到了一个新的历史阶段。随着我国利率市场化的不断深入,利率政策作为货币政策的重要组成部分,它的重要性不言而喻,而行为金融理论认为情绪会对投资者的投资行为决策产生影响,而所有市场参与者的行为又会对某种资产或是整个市场的走势造成影响,因此,研究利率政策变动对我国股票市场以及投资者情绪的影响,对投资者情绪在利率政策传导过程中的作用进行分析,这具有一定的现实意义 ...

Profiling EFL Students’ Motivation and Anxiety in Collaborative Learning: Associations With Teachers’ Support, Self‐Regulated Learning, and Achievement

open access: yesInternational Journal of Applied Linguistics, Volume 36, Issue 2, Page 979-994, May 2026.
ABSTRACT Previous research has established the relationships between motivation, anxiety, teachers’ support, and self‐regulated learning (SRL) in English‐as‐a‐foreign‐language (EFL) learning. Most of the studies, however, have taken a variable‐centered approach in addressing the variable correlations, while learners’ characteristics and variable links ...

Extensive comparison of forest runoff water chemistry [PDF]

open access: yes, 1995
森林流出水の調査を冷温帯から亜熱帯にかけて, 計6地域13集水域において行った。森林流出水の水質について, Cl_-は海洋に近いほど, そして林冠が閉鎖するほど渓流水中の濃度が高くなった。NO_3_-は気候条件に起因するそれぞれの森林における植物-土壌間の窒素循環システムにより渓流水中の濃度が決定される。SO_4_はNO_3_-濃度の高い地域では高濃度であるが, 同地域内の集水域で比較した場合, NO_3_-濃度の高い集水域ではSO_4_濃度が低かった ...

油松飞播造林的地理分布和适宜性分区

open access: yesShuitu Baochi Xuebao, 2000
根据我国北方地区历年油松飞播调查资料和对典型播区的调查,阐明了油松飞播的地理分布和效果;同时运用统计分析和模糊数学分析等方法,对影响油松飞播成效的主要因子作了系统的宏观分析,得出年均降水量和年均气温是影响飞播效果的主要因子。在此基础上,对北方地区油松飞播造林进行了适宜性分区,分区结果将油松飞播划分为3个区,即造林适宜区,造林次适宜区和造在适宜区,对指导今后油松飞播生产具有重要意义。
