We call this TEMPURA noise. It is said that the tone pulse (duration time is about 1 [ms]) was occurred by accompanying with the spouting of the water by rapidly closing the one side scissors greatly developed of a snapping shrimp. In the field of underwater acoustics, TEMPURA noise has consistently been treated as a noise of an unnecessary one. Recently, there is a trend to utilize TEMPURA noise positively as a sound source of the circumference noise imaging sonar or to utilize the number of pulses as an index for marine environment and bottom material evaluation, etc. However, details of occurrence frequency or distribution of TEMPURA noise itself are unclear and an evaluation method of the number of pulses has not also been determined. In this study, a new evaluation method of the number of pulses (for example, pulses per unit time) is discussed. Because we devised a new technique to measure the number of pulses by using the image processing. In addition, by using the new technique, we report the TEMPURA noise measured at a pier of Japan Coast Guard Academy along with the marine environment data.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15053/0000000199","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"海上保安大学校"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.15053/2012.21.01","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10088865","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0287-2951","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"倉本, 和興"},{"creatorName":"クラモト, カズオキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"386","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田中, 隆博"},{"creatorName":"タナカ, タカヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"171","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KURAMOTO, Kazuoki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"387","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TANAKA, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"50","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":"2023-05-31"}],"displaytype":"detail","filename":"2_56-1-78-01_Kuramoto.pdf","filesize":[{"value":"847.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"画像処理を用いた水中テンプラノイズのパルス数計測法について","url":"https://jcga.repo.nii.ac.jp/record/199/files/2_56-1-78-01_Kuramoto.pdf"},"version_id":"3e1e4fbf-2ea7-4ee8-a083-33fe02b2d4bd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"underwater Acoustics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"TEMPURA noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"marine environment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"image processing","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"画像処理を用いた水中テンプラノイズのパルス数計測法について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"画像処理を用いた水中テンプラノイズのパルス数計測法について","subitem_title_language":"ja"},{"subitem_title":"A Measurement Method for Number of the Pulses of Underwater TEMPURA Noise by Image Processing","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["50"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-05-31"},"publish_date":"2023-05-31","publish_status":"0","recid":"199","relation_version_is_last":true,"title":["画像処理を用いた水中テンプラノイズのパルス数計測法について"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2023-10-05T23:03:00.043092+00:00"}
