The characteristic feature of this approach is the use of accurately controlled electromagnetic waves to determine the accurate transfer function between source signal and observed signal. Upon developing the hardware system of EM-ACROSS, the first field test was carried out in the Tono area. The transmitting test and trial observations with a rectangular wave signal from current dipole showed that the system worked well up to 100Hz. Data stacking represented the reduction of the observation noise as accurately as theoretically expected. With stacking for eight hours, signals were detected up to 30Hz at a distance of 3km. Whereas the results obtained so far are preliminary, the ACROSS approach is thought to have potential for underground exploration and monitoring.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"126498","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakajima, Takahiro"}]},{"nameIdentifiers":[{"nameIdentifier":"126499","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kunitomo, Takahiro"}]},{"nameIdentifiers":[{"nameIdentifier":"126500","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kumazawa, Mineo"}]},{"nameIdentifiers":[{"nameIdentifier":"126501","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yokoyama, Yukiko"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032641","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"核燃料サイクル開発機構東濃地科学センター"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中島, 崇裕"}],"nameIdentifiers":[{"nameIdentifier":"126494","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"國友, 孝洋"}],"nameIdentifiers":[{"nameIdentifier":"126495","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"熊澤, 峰夫"}],"nameIdentifiers":[{"nameIdentifier":"126496","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"横山, 由紀子"}],"nameIdentifiers":[{"nameIdentifier":"126497","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-26"}],"displaytype":"detail","filename":"ji0753005.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0753005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32641/files/ji0753005.pdf"},"version_id":"5a60de5b-72e2-49dd-ab00-289c460a7342"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"electromagnetic sounding","subitem_subject_scheme":"Other"},{"subitem_subject":"synchronization","subitem_subject_scheme":"Other"},{"subitem_subject":"ACROSS","subitem_subject_scheme":"Other"},{"subitem_subject":"monitoring","subitem_subject_scheme":"Other"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"電磁アクロスの開発と送信実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"電磁アクロスの開発と送信実験","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4650","4652"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32641","relation_version_is_last":true,"title":["電磁アクロスの開発と送信実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:15.773903+00:00"}
