In this study, an optimal design technique of multifunctional SAW devices is developed for reducing the number of electronic parts used in RF circuits. The results of this study can be summarized by the following three points. 1) The structural design of a SAW filter is formulated as a three-objective optimization problem. Then a Multi-Objective Evolutionary Algorithm (MOEA) based on the latest EA, i.e., Differential Evolution (DE), is applied to the optimization problem. In order to analyze the relationship between the structure of electrodes and the device function, a set of solutions obtained by MOEA is evaluated statistically by using the principal component analysis. 2) A new MOEA is proposed for solving the multi-objective optimization problems which have more than four objectives. A fast approximation algorithm for the exclusive hypervolume is used by the new MOEA as the criterion of solutions. 3) In order to utilize multi-core CPUs for the design of multifunctional SAW devices, a concurrent program of DE is developed.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究（C）;  研究期間：2009～2011;   課題番号：21560432;   研究分野：工学;   科研費の分科・細目：電気電子工学・システム工学","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/d/r/50252789.ja.html"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"TAGAWA, KIYOHARU"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 教授"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田川,  聖治"},{"creatorName":"タガワ, キヨハル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"KAKEN_21560432seika.pdf","filesize":[{"value":"368.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_21560432seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3211/files/KAKEN_21560432seika.pdf"},"version_id":"c92c7b37-198d-4006-98e2-e75c909f888e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"生産システム工学","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"多機能弾性波デバイスの電極構造解析と同時最適設計に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多機能弾性波デバイスの電極構造解析と同時最適設計に関する研究"}]},"item_type_id":"8","owner":"3","path":["2686","2688"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-22"},"publish_date":"2012-10-22","publish_status":"0","recid":"3211","relation_version_is_last":true,"title":["多機能弾性波デバイスの電極構造解析と同時最適設計に関する研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:43:02.021250+00:00"}
