时空聚类算法是地理时空大数据挖掘的基础研究命题。针对传统CFSFDP聚类算法无法应用于时空数据挖掘的问题,本文提出一种时空约束的ST-CFSFDP(spatial-temporal clustering by fast search and find of density peaks)算法。在CFSFDP算法基础上加入时间约束,修改了样本属性值的计算策略,不仅解决了原算法单簇集多密度峰值问题,且可...
为深入研究煤矿井下串联故障电弧特征及提取方法,分别以电动机和变频器负载为研究对象,开展不同电流条件下的串联型故障电弧实验。采用S变换(ST)对回路电流进行时频域变换,求得S变换矩阵的幅值矩阵作为特征矩阵;对特征矩阵进行奇异分解(SVD),得到矩阵的奇异值;对多组奇异值组成的特征向量进行主元分析(PCA),选取累积贡献率高于95%的主元作为故障识别的特征,实现特征向量的降维;最后采用遗传算法(GA)...
2017年11月9-13日,英国国王大学滑铁卢校区院长Stephen Stürzenbaum教授应三峡生态环境研究所裴得胜研究员的邀请,来访重庆研究院,并作题为“Juggling essential and toxic metals: a worm's eye view of a Toxicogenomic challenge”的主题学术报告。会议由裴得胜研究员主持,三峡所的老师与学生聆听报告并进...
The historical architectural heritage may be considered as the product of a complex system of interaction between several factors - cultural, socio-economic, technical, aesthetic etc. The restoration ...
Close-range photogrammetry is an image-based technique which has often been used for the 3D documentation of heritage objects. Recently, advances in the field of image processing and UAVs (Unmanned Ae...
We report an experimental realization of the geometric Landau-Zener-Stückelberg (LZS) interferometry proposedbyGasparinettietal [Phys.Rev.Lett.107,207002(2011)]inasingle-trapped-ionsystem.Unlikethose ...
When it was built, St. Ninian’s Cathedral, in Antigonish, Nova Scotia, Canada had nearly every interior surface covered with trompel’oeil frescoes framing saints and scenes depicting the mysteries of ...
在中国科学院与明尼苏达大学签订的合作协议备忘录框架下,由中国科学院地球环境研究所和明尼苏达大学共同组织,第二届UMN-CAS双边论坛在美国明尼苏达州双城Minneapolis-St.Paul成功举办。本次论坛在世界著名企业3M公司创新中心举办,主题为“PM2.5 Science, Health Effects, and Control Technology”, 瞄准大气颗粒物监测与控制技术、传输与...
In this contribution the possibility to combine terrestrial laser scanner (TLS) measurements and UAS photogrammetry for the detailed description and high quality surveying of a cultural monument will ...

This paper is about a complete photogrammetric record of St. Domingo de Silos’ Church (XIV th century), in Alcala la Real (Jaen, Spain). It was declared National Monument in 1931. At present it is ...
Ilex paraguariensis A.St.-Hil., (yerba mate) has been gaining space in face of the larger demand for alternative raw materials in food production. The study aimed to develop a bread formulation with a...
This paper is part of a research about ribbed vaults systems in French Gothic Cathedrals. Our goal is to compare some different gothic cathedrals to understand the complex geometry of the ribbed vault...
Medieval town centres and landscapes along the Way of St. James are being affected by renewable energy sources at the architectural, urban and territorial scales. The impact is not only visual, but th...
Consecrated in 1297 as the monastery church of the four years earlier founded St. Catherine’s monastery, the Gothic Church of St. Catherine was largely destroyed in a devastating bombing raid on Jan...
