A wavelet BEM provides a sparse coefficient matrix by truncating a small value in the matrix entries based on a specifiedthreshold. In discretization process, the collocation method requires the wavelets as bases of anapproximate solution, while the Galerkin method requires wavelets not only as bases of numerical solutionbut as weighting functions. The wavelet BEM is usually derived by the Galerkin method because of high sparsity and good condition of the matrix. However the Galerkin method requires double integration on the boundary. Therefore, in conventional BEMs, the discretized equations are derived based on the collocation method. In this study, improvement of the wavelet collocation BEM is attempted by applying the discrete wavelet transform to the system matrix. Through numerical examples, comparison of performance of the proposed method with the collocation and Galerkin methods is carried out and the validity of the method is investigated.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "39329", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Koro, Kazuhiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "39330", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Abe, Kazuhisa"}]}, {"nameIdentifiers": [{"nameIdentifier": "39331", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Tazaki, Hiroaki"}]}]}, "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/journalam1998/2/0/2_0_153/_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": "AA12492021", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "13459139", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "紅露, 一寛"}], "nameIdentifiers": [{"nameIdentifier": "39326", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "阿部, 和久"}], "nameIdentifiers": [{"nameIdentifier": "39327", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "田崎, 浩章"}], "nameIdentifiers": [{"nameIdentifier": "39328", "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", "download_preview_message": "", "file_order": 0, "filename": "2_153-162.pdf", "filesize": [{"value": "1.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1700000.0, "url": {"label": "2_153-162.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2831/files/2_153-162.pdf"}, "version_id": "9f6eeb35-0806-4308-aedb-e9bcc09c6db8"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "boundary element method", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Haar wavelet", "subitem_subject_scheme": "Other"}, {"subitem_subject": "discrete wavelet transform", "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": "離散wavelet変換による選点法境界要素解析の効率化", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "離散wavelet変換による選点法境界要素解析の効率化"}, {"subitem_title": "離散wavelet変換による選点法境界要素解析の効率化", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "470"], "permalink_uri": "http://hdl.handle.net/10191/24752", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-01-20"}, "publish_date": "2014-01-20", "publish_status": "0", "recid": "2831", "relation": {}, "relation_version_is_last": true, "title": ["離散wavelet変換による選点法境界要素解析の効率化"], "weko_shared_id": null}
