1Spatial cloud computing: how can the geospatial sciences use and help shape cloud computing?显示文摘The geospatial sciences face grand information technology(IT)challenges in the twenty-first century:data intensity,computing intensity,concurrent access intensity and spatiotemporal intensity.These challenges require the readiness of a computing infrastructure that can:(1)better support discovery,access and utilization of data and data processing so as to relieve scientists and engineers of IT tasks and focus on scientific discoveries;(2)provide real-time IT resources to enable real-time applications,such as emergency response;(3)deal with access spikes;and(4)provide more reliable and scalable service for massive numbers of concurrent users to advance public knowledge.The emergence of cloud computing provides a potential solution with an elastic,on-demand computing platform to integrateobservation systems,parameter extracting algorithms,phenomena simulations,analytical visualization and decision support,and to provide social impact and user feedbackthe essential elements of the geospatial sciences.We discuss the utilization of cloud computing to support the intensities of geospatial sciences by reporting from our investigations on how cloud computing could enable the geospatial sciences and how spatiotemporal principles,the kernel of the geospatial sciences,could be utilized to ensure the benefits of cloud computing.Four research examples are presented to analyze how to:(1)search,access and utilize geospatial data;(2)configure computing infrastructure to enable the computability of intensive simulation models;(3)disseminate and utilize research results for massive numbers of concurrent users;and(4)adopt spatiotemporal principles to support spatiotemporal intensive applications.The paper concludes with a discussion of opportunities and challenges for spatial cloud computing(SCC).Chaowei Yang Michael Goodchild Qunying Huang Doug Nebert Robert Raskin Yan Xu Myra Bambacus Daniel Fay 2011International Journal of Digital Earth2011,4,4:55
2氨甲环酸在全髋关节置换术中的应用进展显示文摘目的:通过回顾既往公开发表的研究所提供的证据,对全髋关节置换术中使用氨甲环酸来减少出血量的有效性及安全性进行评估,同时对氨甲环酸的最佳剂量及给药方式进行探讨。方法:以'Tranexamic acid;Total hip arthroplasty;Blood loss;Method of administration;Venous thromboembolism'为检索词,对Pub Med,Medline,Cochrane,Ovid,Science Direct数据库进行检索,纳入标准:(1)英文文献;(2)患者为成年患者;(3)文章主题为氨甲环酸在全髋关节置换术中的应用。排除标准:(1)关于其他关节置换手术的研究;(2)关于根治性矫形手术的研究。结果:(1)使用氨甲环酸可减少全髋关节置换术术后的出血;(2)通过与安慰剂组或对照组进行比较可以发现氨甲环酸组患者深静脉血栓形成的发病率低于安慰剂或对照组;(3)氨甲环酸的给药途径包括静脉给药(最常见),局部给药和口服给药(最少见);(4)对于不同的给药途径,给药时间导致给药剂量也存在很大分歧。结论:氨甲环酸应用于全髋关节置换术,可以降低术中和术后失血量,尤其是术后失血量,进而降低临床输血量,降低因失血和输血导致的感染等并发症和副反应发生的风险。同时,氨甲环酸安全性良好,并不会额外增加静脉血栓栓塞发生的风险。但是,现有研究在给药途径和使用剂量等方面仍存在很大分歧,因此,未来的工作重点应集中于如何就氨甲环酸在全髋关节置换术中的使用时间、给药途径和使用剂量等方面进行优化,取得共识。Raskin Shakya 亓一鸣 芮云峰 陈辉 2018东南大学学报(医学版)2018,37,1:8

8Towards geospatial semantic search:exploiting latent semantic relations in geospatial data显示文摘This paper reports our efforts to address the grand challenge of the Digital Earth vision in terms of intelligent data discovery from vast quantities of geo-referenced data.We propose an algorithm combining LSA and a Two-Tier Ranking(LSATTR)algorithm based on revised cosine similarity to build a more efficient search engine-Semantic Indexing and Ranking(SIR)-for a semantic-enabled,more effective data discovery.In addition to its ability to handle subject-based search,we propose a mechanism to combine geospatial taxonomy and Yahoo!GeoPlanet for automatic identification of location information from a spatial query and automatic filtering of datasets that are not spatially related.The metadata set,in the format of ISO19115,from NASA's SEDAC(Socio-Economic Data Application Center)is used as the corpus of SIR.Results show that our semantic search engine SIR built on LSATTR methods outperforms existing keyword-matching techniques,such as Lucene,in terms of both recall and precision.Moreover,the semantic associations among all existing words in the corpus are discovered.These associations provide substantial support for automating the population of spatial ontologies.We expect this work to support the operationalization of the Digital Earth vision by advancing the semantic-based geospatial data discovery.Wenwen Li Michael FGoodchild Robert Raskin 2014International Journal of Digital Earth2014,7,1:2
