A function based on normalized fourth-order cumulant, kurtosis, is used to detect both provisional P-wave arrival time and the end of microseismic signal. The contrast function has the maximum value near the P-wave arrival time. After detection of the provisional P-wave arrival time, maximum likelihood analysis is applied to evaluate residuals between microseismic signal and its AR model, which is made based on the provisional P-wave arrival time. 100 of microseismic events are used to examine the performance of this automatic detection. Errors of the automatic detection are within 3 ms in the 97 events. 3 ms is as long as a quarter of a period of P-wave because dominant frequency of P-wave is 80Hz.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_79_link_17":{"attribute_name":"出版者版へのリンク","attribute_value_mlt":[{"subitem_link_text":"10.11367/grsj1979.29.195","subitem_link_url":"https://doi.org/10.11367/grsj1979.29.195"}]},"item_79_link_5":{"attribute_name":"室蘭工業大学研究者データベースへのリンク","attribute_value_mlt":[{"subitem_link_text":"永野 宏治（NAGANO Koji）","subitem_link_url":"http://rdsoran.muroran-it.ac.jp/html/100000251_ja.html"}]},"item_79_publisher_11":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本地熱学会","subitem_publisher_language":"ja"}]},"item_79_relation_15":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10019784184","subitem_relation_type_select":"NAID"}}]},"item_79_relation_18":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11367/grsj1979.29.195","subitem_relation_type_select":"DOI"}}]},"item_79_source_id_12":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03886735","subitem_source_identifier_type":"PISSN"}]},"item_79_source_id_14":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00333995","subitem_source_identifier_type":"NCID"}]},"item_79_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_79_version_type_21":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{}],"affiliationNames":[{},{}]}],"creatorNames":[{"creatorName":"永野,  宏治","creatorNameLang":"ja"},{"creatorName":"NAGANO, Koji","creatorNameLang":"en"},{"creatorName":"ナガノ, コウジ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"岩本, 佑介","creatorNameLang":"ja"},{"creatorName":"IWAMOTO, Yusuke","creatorNameLang":"en"},{"creatorName":"イワモト, ユウスケ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-15"}],"displaytype":"detail","filename":"JGeotherm_29(4)_195-202.pdf","filesize":[{"value":"786.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JGeotherm_29(4)_195-202.pdf","objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/6653/files/JGeotherm_29(4)_195-202.pdf"},"version_id":"fdd4c647-d694-47ff-b4ff-fad94704a227"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"microearhquake","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"automatic detection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"detection,higher-order statistics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"kurtosis","subitem_subject_language":"en","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"尖度解析と最尤推定法を組み合せた微小地震のP波入力時刻自動検出法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"尖度解析と最尤推定法を組み合せた微小地震のP波入力時刻自動検出法","subitem_title_language":"ja"},{"subitem_title":"Automatic Picking of Microearthquake P-wave Using Kurtosis Analysis and Maximum Likelihood Analysis","subitem_title_language":"en"}]},"item_type_id":"79","owner":"18","path":["46","286"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-07-29"},"publish_date":"2008-07-29","publish_status":"0","recid":"6653","relation_version_is_last":true,"title":["尖度解析と最尤推定法を組み合せた微小地震のP波入力時刻自動検出法"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-16T04:59:23.749919+00:00"}
