The ROM is an efficient tool to calculate a flow field in real-time because the ROM consumes extremely less computational time than the original numerical model. The PF is employed to estimate coefficients of the ROM by using observed velocity components in the wake of the circular cylinder. Comparing the result of the ROM and that of the numerical analysis by Building Cube Methods (BCM), the phase difference of the Karman vortex between the ROM and the observations was corrected. The proposed method could estimate the flow field accurately in real-time even though the observation contained artificial measurement errors.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0062268015","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-13-011","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東北大学流体科学研究所"},{"subitem_text_value":"東北大学流体科学研究所"},{"subitem_text_value":"東北大学流体科学研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Fluid Science, Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Fluid Science, Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Fluid Science, Tohoku University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"菊地, 亮太"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三坂, 孝志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大林, 茂"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kikuchi, Ryota","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Misaka, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Obayashi, Shigeru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"62268015.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"62268015.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4015/files/62268015.pdf"},"version_id":"bbd471ff-908d-4010-8371-fd3616c1ce76"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"縮約モデルと粒子フィルタを用いたリアルタイムデータ同化計算","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"縮約モデルと粒子フィルタを用いたリアルタイムデータ同化計算"}]},"item_type_id":"5","owner":"1","path":["877","1536","1880","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4015","relation_version_is_last":true,"title":["縮約モデルと粒子フィルタを用いたリアルタイムデータ同化計算"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:49:54.482435+00:00"}
