2013/11/30
为了研究快速识别虫眼枣与正常枣的有效方法,利用特征波长主成分分析法结合波段比算法进行虫眼枣识别。首先,利用NIR高光谱成像系统采集130个长枣(50个正常、80个虫眼枣)图像,提取并分析不同类型长枣特征区域的平均光谱曲线,对970~1 670 nm范围内的光谱数据进行主成分分析,确定7个特征波长(990,1 028,1 109,1 160,1 231,1 285,1 464 nm)。然后,对长枣图...
Infrared two-colour diagrams for AGB stars using AKARI, MSX, IRAS and NIR data
stars: AGB and post-AGB - circumstellar matter - infrared: stars - dust extinction - radiative transfer
2011/10/12
Using a revised version of the catalog of AGB stars by Suh & Kwon (2009), we present various infrared two-colour diagrams (2CDs) for 3003 O-rich, 1168 C-rich, 362 S-type and 35 silicate carbon stars i...
Star-forming Region Sh 2-233IR I. Deep NIR Observations toward the Embedded Stellar Clusters
Star-forming Sh 2-233IR Observations Embedded Stellar Clusters
2011/10/9
We observed the Sh 2-233IR (S233IR) region with better sensitivity in near-infrared than previous studies for this region. By applying statistical subtraction of the back- ground stars, we identified ...
Current studies of the peculiar velocity flow field in the Local Universe are limited by the lack of detection of galaxies behind the Milky Way. The contribution of the largely unknown mass distributi...
