The second law of thermodynamics should constrain the upper limit of an extra driving term of the acceleration equation in the present model. The upper limit implies that the order of the driving term is likely consistent with the order of the cosmological constant measured by observations.\nIn addition, a power-law term is applied to the present model, in order to systematically examine dissipative and nondissipative universes from a thermodynamics viewpoint. Consequently, a nondissipative model is found to be consistent with observations and satisfy the thermodynamic constraints related to the maximization of entropy. This result shows that the nondissipative universe is likely favored.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:18K03613, 研究期間(年度):2018-04-01 – 2021-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：「ホログラフィー等分配則と非加法的エントロピーに基づく革新的宇宙論モデルの構築」研究成果報告書　課題番号18K03613\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-18K03613/18K03613seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域機械工学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00059083","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/search/?kw=20436827"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/search/?kw=20436827","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-18K03613/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-18K03613/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-18K03613/18K03613seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-18K03613/18K03613seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-03-03"}],"displaytype":"detail","filename":"TE-PR-KOMATSU-N-kaken 2021-8p.pdf","filesize":[{"value":"508.2 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-KOMATSU-N-kaken 2021-8p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/52790/files/TE-PR-KOMATSU-N-kaken 2021-8p.pdf"},"version_id":"7ba41a25-6feb-413e-bc46-ee1b213e601a"}]},"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":"ホログラフィー等分配則と非加法的エントロピーに基づく革新的宇宙論モデルの構築","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ホログラフィー等分配則と非加法的エントロピーに基づく革新的宇宙論モデルの構築"},{"subitem_title":"Cosmological model from the holographic equipartition law with a nonadditive entropy","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["4014"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-03-03"},"publish_date":"2022-03-03","publish_status":"0","recid":"52790","relation_version_is_last":true,"title":["ホログラフィー等分配則と非加法的エントロピーに基づく革新的宇宙論モデルの構築"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T13:43:32.981275+00:00"}
