He obtained almost complete results in the case of two space dimensions. FUKUMOTO studied the evolution of viscous vortices, applying the singular perturbation method to the non-local induction model, and obtained new results on the topological change of vortex filaments and rings. HISHIDA studied the viscous flow around a rotating body and proved for the first time the existence of stationary and nonstationary flows by finding a new class of singular integral operators. He also gave a new existence result for flows in domains with apertures. IGUCHI applied the method for treating free-surface problem to the equation of one-dimensional gas dymanics and gave a completely new approach to this problem which has wide applications to equations of similar types. He also classified the shape of free surfaces associated with shallow water flow with periodic bottom, applying the bifurcation theory.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:15340054, 研究期間(年度):2003 – 2005","subitem_description_type":"Other"},{"subitem_description":"出典：「流れに伴う渦と波動のパターン変化の研究」研究成果報告書　課題番号15340054\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所））\n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-15340054/153400542005kenkyu_seika_hokoku_gaiyo/)を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学自然科学研究科","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00063424","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/search/?kw=10033929"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=10033929","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-15340054/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-15340054/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-15340054/153400542005kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-15340054/153400542005kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"宮川, 鉄朗"}],"nameIdentifiers":[{"nameIdentifier":"95595","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10033929","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=10033929"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-11-04"}],"displaytype":"detail","filename":"SC-PR-MIYAKAWA-T-kaken 2007-3p.pdf","filesize":[{"value":"119.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-MIYAKAWA-T-kaken 2007-3p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/57154/files/SC-PR-MIYAKAWA-T-kaken 2007-3p.pdf"},"version_id":"5bfc0325-dec9-41d7-b876-a2bd532db7ca"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"流れに伴う渦と波動のパターン変化の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"流れに伴う渦と波動のパターン変化の研究"},{"subitem_title":"Study on the change of patterns of vortices and waves in fluid flow.","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2828"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-11-04"},"publish_date":"2021-11-04","publish_status":"0","recid":"57154","relation_version_is_last":true,"title":["流れに伴う渦と波動のパターン変化の研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T06:19:58.472281+00:00"}
