In this paper, the method of normalized input-output minimization (NIOM) is modified, and this modified NIOM method is used to analyze microtremors recorded at three different vertical-array sites in Japan. The main features of this study include using simultaneously recorded vertical-array microtremors, finding the direction of wave propagation by modeling the observed correlated waves, and obtaining the average particle motion to determine the type of wave present.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_other_language_22":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人土木学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18827187","subitem_source_identifier_type":"ISSN"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Kawakami, Hideji"},{"subitem_text_value":"SUN, Yaonan"},{"subitem_text_value":"YANG, Zhongyuan"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002679"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学教授地圏科学研究センター"},{"subitem_text_value":"埼玉大学理工学研究科"},{"subitem_text_value":"株式会社日本建設技術社"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Geosphere Research Institute of Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2003-7"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"川上, 英二"},{"creatorName":"カワカミ, ヒデジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"孫, 耀南"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"楊, 仲元"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002679.pdf","filesize":[{"value":"905.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002679.pdf","url":"https://sucra.repo.nii.ac.jp/record/14352/files/A1002679.pdf"},"version_id":"d92fb424-b3f3-4a32-aeec-940c553eecc0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"wave propagation","subitem_subject_scheme":"Other"},{"subitem_subject":"waveform analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Rayleigh waves","subitem_subject_scheme":"Other"},{"subitem_subject":"spectral analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"seismic array","subitem_subject_scheme":"Other"},{"subitem_subject":"microtremors","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"波動伝播と土粒子軌跡のモデル化による地表および地中の常時微動記録の解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"波動伝播と土粒子軌跡のモデル化による地表および地中の常時微動記録の解析"}]},"item_type_id":"119","owner":"3","path":["242"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-06-02"},"publish_date":"2008-06-02","publish_status":"0","recid":"14352","relation_version_is_last":true,"title":["波動伝播と土粒子軌跡のモデル化による地表および地中の常時微動記録の解析"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T19:00:24.215786+00:00"}
