The method introduces polar coordinates centred at the source projection, and then employs radial and angular variable transformations to weaken the near singularity before applying standard quadrature. Several radial variable transformations, which are particularly important in the method, will be presented. Then, error analysis using complex function theory yields insight regarding the optimal radial variable transformation. Finally, we will discuss the efficient use of the double exponential transformation in the radial variable transformation.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20736/0000000406","subitem_identifier_reg_type":"JaLC"}]},"item_5_publisher_31":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立情報学研究所","subitem_publisher_language":"ja"}]},"item_5_source_id_32":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-5597","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"速水, 謙","creatorNameLang":"ja"},{"creatorName":"Hayami, Ken","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-08-27"}],"displaytype":"detail","filename":"05-010E.pdf","filesize":[{"value":"235.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NII Technical Report (NII-2005-010E)：Variable Transformations for Nearly Singular Integrals in the Boundary Element Method","url":"https://repository.nii.ac.jp/record/406/files/05-010E.pdf"},"version_id":"781af1d5-43ea-4c9f-a1e7-5020da4e02b9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"テクニカルレポート","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Technical Report","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"NII Technical Report (NII-2005-010E)：Variable Transformations for Nearly Singular Integrals in the Boundary Element Method","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"NII Technical Report (NII-2005-010E)：Variable Transformations for Nearly Singular Integrals in the Boundary Element Method","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["136"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2005-06-09"},"publish_date":"2005-06-09","publish_status":"0","recid":"406","relation_version_is_last":true,"title":["NII Technical Report (NII-2005-010E)：Variable Transformations for Nearly Singular Integrals in the Boundary Element Method"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-27T07:45:54.024378+00:00"}
