Computational cost reduction is undoubtedly thought to be a common problem of most Aerodynamic shape optimization. In this approach, Artificial Neural Network (ANN) is used for function approximation; a number of mathematical computations are performed on the approximated function to obtain a reduced model. This resulting mathematical model is used to locate the variables that affect most the cost function. This approach is first tested on analytical functions, then numerical experimentations are conducted to solve shape optimization problem for the design of a wing profile. For each evaluation required by the optimizer, the Navier-Stokes equations with the Baldwin-Lomax turbulence model are solved.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0048469026","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-04-012","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"名古屋大学 大学院工学研究科"},{"subitem_text_value":"名古屋大学 大学院工学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nagoya University Graduate School of Engineering"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University Graduate School of Engineering"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Rousseau, Yannick"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中村, 佳朗"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Rousseau, Yannick","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamura, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"48469026.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"48469026.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6466/files/48469026.pdf"},"version_id":"f5c474c7-3605-46f0-9416-e3a5b97ab95b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"遺伝的アルゴリズム","subitem_subject_scheme":"Other"},{"subitem_subject":"人工ニューラルネットワーク","subitem_subject_scheme":"Other"},{"subitem_subject":"空気力学","subitem_subject_scheme":"Other"},{"subitem_subject":"空力最適化","subitem_subject_scheme":"Other"},{"subitem_subject":"航空機設計","subitem_subject_scheme":"Other"},{"subitem_subject":"設計最適化","subitem_subject_scheme":"Other"},{"subitem_subject":"CPU","subitem_subject_scheme":"Other"},{"subitem_subject":"サーチスペースリダクション","subitem_subject_scheme":"Other"},{"subitem_subject":"genetic algorithm","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"artificial neural network","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerodynamics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerodynamic optimization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aircraft design","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"design optimization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CPU","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"search space reduction","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Acceleration of GA in aerodynamics by search space reduction and artificial neural","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Acceleration of GA in aerodynamics by search space reduction and artificial neural","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1073","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6466","relation_version_is_last":true,"title":["Acceleration of GA in aerodynamics by search space reduction and artificial neural"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:55:15.043137+00:00"}
