The coefficient matrices are compressed using the Beylkin-type level-independent truncation scheme with a DOF-independent prescribed threshold value. The number of non-zero entries of the matrix G(L,p) and H(L,p) (1 ≤ p ≤ L, L: current time step), N(G(L,p)) and N(H(L,p)), increases in proportion to the factors log N, N1/2, N and N log N, except for the behavior in the smaller DOF range where N(G(L,p)) and N(H(L,p))∼O(N2). For M»1 and N»1, N(G(L,p)) and N(H(L,p)) show O(N log N) in matrix compression with a prescribed threshold value λ.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"43551","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Koro, Kazuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"43552","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Abe, Kazuhisa"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/article/jscejam/67/2/67_2_I_95/_pdf","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"公益社団法人土木学会"},{"subitem_rights":"本文データは学協会の許諾に基づきJ-Stageから複製したものである"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12373113","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"紅露, 一寛"}],"nameIdentifiers":[{"nameIdentifier":"43549","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"阿部, 和久"}],"nameIdentifiers":[{"nameIdentifier":"43550","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":"2019-07-30"}],"displaytype":"detail","filename":"67_2_95-106.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"67_2_95-106.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3544/files/67_2_95-106.pdf"},"version_id":"b34e266d-6c49-499d-b336-622640fc5c34"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"time-domain BEM","subitem_subject_scheme":"Other"},{"subitem_subject":"Haar wavelet","subitem_subject_scheme":"Other"},{"subitem_subject":"matrix compression","subitem_subject_scheme":"Other"},{"subitem_subject":"diffusion equation","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":"Haar waveletを用いた2次元拡散問題時間域境界要素法における係数行列保存成分数の解析自由度依存性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Haar waveletを用いた2次元拡散問題時間域境界要素法における係数行列保存成分数の解析自由度依存性"},{"subitem_title":"Haar waveletを用いた2次元拡散問題時間域境界要素法における係数行列保存成分数の解析自由度依存性","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","470"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-01-08"},"publish_date":"2014-01-08","publish_status":"0","recid":"3544","relation_version_is_last":true,"title":["Haar waveletを用いた2次元拡散問題時間域境界要素法における係数行列保存成分数の解析自由度依存性"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:39.909808+00:00"}
