论文按照Oracle数据挖掘流程,利用数据挖掘工具Oracle Data Miner,采用Oracle数据挖掘专有的正交分割聚类算法,介绍了如何将Oracle数据挖掘技术应用于为了促进能源的节能降耗而建设的城市能源计量数据平台,以达到对服务平台采集的能耗...论文按照Oracle数据挖掘流程,利用数据挖掘工具Oracle Data Miner,采用Oracle数据挖掘专有的正交分割聚类算法,介绍了如何将Oracle数据挖掘技术应用于为了促进能源的节能降耗而建设的城市能源计量数据平台,以达到对服务平台采集的能耗数据的充分利用。最终确定将该技术应用于福建某公司的煤耗数据研究,通过对正交分割聚类算法应用所取得的数据挖掘结果进行分析和知识说明,为煤炭行业的节能降耗提供科学决策依据。展开更多
In architecture and urban design,solar energy plays an important role to save fossil energy and preserve environment.Passive or active use of this energy needs especial consideration in the preliminary stage of design...In architecture and urban design,solar energy plays an important role to save fossil energy and preserve environment.Passive or active use of this energy needs especial consideration in the preliminary stage of design to the probable shadows.This work will answer two questions:1) How is it possible to distinguish shadow need periods during a year in a specific climate-2) How is it possible to produce shadow in hot periods without being deprived of pleasant sunshine in cold periods-In this regard,it will introduce the usage process and opportunities of "shading mask" of Olgyay as an easy and useful graphical method in six steps.At the end,different ways of using this method in design will be discussed.Several research projects that have been done in past 30 years will support the argument as examples of this method.展开更多
