This formula gives the symmetric relation between the two mortality coefficients Ｆ and M for the generating function. Hiramatsu's formula for the constant catch model with seasonality is also obtained from the constant fishing mortality coefficient model with seasonality by using the approximation relating to the generating function. The convergence of Ishioka-Kishida's iteration method, which is rapid and stable is proved by using the principle of contraction. For rough estimation, when the natural mortality coefficient M is smaller than 4, it will converge.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"中央水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Research Institute Fisheries Research","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nri_k_1","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010630384","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10358460","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-8014","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Akamine, Tatsuro","creatorNameLang":"en"},{"creatorName":"赤嶺, 達郎","creatorNameLang":"ja"},{"creatorName":"アカミネ, タツロウ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Akamine","familyNameLang":"en"},{"familyName":"赤嶺","familyNameLang":"ja"},{"familyName":"アカミネ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tatsuro","givenNameLang":"en"},{"givenName":"達郎","givenNameLang":"ja"},{"givenName":"タツロウ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2059","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90371822","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=90371822"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"VPA; cohort analysis; approximate expression; iteration method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"VPA; コホート解析; 近似式; 反復法","subitem_subject_language":"ja","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":"VPAにおける近似式と反復法の数学的検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"VPAにおける近似式と反復法の数学的検討","subitem_title_language":"ja"},{"subitem_title":"Mathematical Study for Approximations and Iterations of the Virtual Population Analysis","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951104833"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-05-21"},"publish_date":"2024-05-21","publish_status":"0","recid":"2005141","relation_version_is_last":true,"title":["VPAにおける近似式と反復法の数学的検討"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-01T05:17:22.152885+00:00"}
