Both models are based on Voronoi tessellation of given points on a sphere. We allocate a given number of points called “generators”, which can be related to pore frames, and obtained their Voronoi tessellation and approximated polyhedron. The first model is based on random allocation of generators, and the second one is based on global minimization of a potential function whose value is calculated from a generator distribution. Depending on the types of these generator distributions, we obtained different types of approximated polyhedrons. Using these polyhedrons, we analyzed the frequency distributions of the number of vertices of the polygons and the total edge lengths. We then compared the polyhedrons derived by the tessellation with real radiolaria. A comparison of frequency distributions revealed that the first model is not sufficient for mesh-like radiolaria. However, the second model had similar distribution to that of another type of spherical radiolaria which has almost regular structure. Under the condition of same number of generators, the second model produces approximately 6 percent smaller total edge length than the first model.","subitem_description_type":"Abstract"}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Society for Science on Form"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11297304","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09116036","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yoshino, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"4953","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuoka, Atsushi"}],"nameIdentifiers":[{"nameIdentifier":"4954","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kurihara, Toshiyuki"}],"nameIdentifiers":[{"nameIdentifier":"4955","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishida, Naoto"}],"nameIdentifiers":[{"nameIdentifier":"4956","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kishimoto, Naoko"}],"nameIdentifiers":[{"nameIdentifier":"4957","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kimoto, Katsunori"}],"nameIdentifiers":[{"nameIdentifier":"4958","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuura, Shu"}],"nameIdentifiers":[{"nameIdentifier":"4959","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-29"}],"displaytype":"detail","filename":"27_45-53.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"27_45-53.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1678/files/27_45-53.pdf"},"version_id":"a51c4939-414d-496c-9e97-394561ed90a2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Spherical Radiolaria","subitem_subject_scheme":"Other"},{"subitem_subject":"Voronoi Tessellation","subitem_subject_scheme":"Other"},{"subitem_subject":"Geometrical Model","subitem_subject_scheme":"Other"},{"subitem_subject":"Skeleton Form","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Application of Voronoi Tessellation of Spherical Surface to Geometrical Models of Skeleton Forms of Spherical Radiolaria","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Application of Voronoi Tessellation of Spherical Surface to Geometrical Models of Skeleton Forms of Spherical Radiolaria"},{"subitem_title":"Application of Voronoi Tessellation of Spherical Surface to Geometrical Models of Skeleton Forms of Spherical Radiolaria","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","470"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-11-27"},"publish_date":"2014-11-27","publish_status":"0","recid":"1678","relation_version_is_last":true,"title":["Application of Voronoi Tessellation of Spherical Surface to Geometrical Models of Skeleton Forms of Spherical Radiolaria"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:24.538603+00:00"}
