Using the preparation equipment with the temperature control unit, the stable preparations of the proposed tags, which use the thermal phase transition in liquid crystals for patterning of artificial patterns, were achieved. This enables us to estimate tags precisely. Image processing programs suitable to kinds of the liquid crystal textures also have been developed.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：挑戦的萌芽研究;  研究期間：2013～2014;   課題番号：25630309;   研究分野：電子工学;   科研費の分科・細目：","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/80324333.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":"NAKAYAMA, Keizo"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 講師"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kinki University"}]},"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":"中山,  敬三"},{"creatorName":"ナカヤマ, ケイゾウ","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":"25630309seika.pdf","filesize":[{"value":"590.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25630309seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/2952/files/25630309seika.pdf"},"version_id":"927f93f3-233b-4861-ba20-7be3266035f1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"液晶","subitem_subject_scheme":"Other"},{"subitem_subject":"セキュリティ","subitem_subject_scheme":"Other"},{"subitem_subject":"ランダム","subitem_subject_scheme":"Other"},{"subitem_subject":"指紋状組織","subitem_subject_scheme":"Other"},{"subitem_subject":"シュリーレン組織","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":"液晶のランダムテクスチャを用いた光セキュリティタグ認証システムの構築","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"液晶のランダムテクスチャを用いた光セキュリティタグ認証システムの構築"}]},"item_type_id":"8","owner":"3","path":["2668","2670"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-11-19"},"publish_date":"2015-11-19","publish_status":"0","recid":"2952","relation_version_is_last":true,"title":["液晶のランダムテクスチャを用いた光セキュリティタグ認証システムの構築"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:51:28.255033+00:00"}
