The occupancies of sunspot pixels in Continuum and of pixels for positive and the negative magnetic polarities in Magnetogram are calculated. By box-counting method, packing exponents for sunspot pixels in Continuum and packing exponents for positive polarity pixels and negative polarity pixels in Magnetogram are evaluated. Packing exponents of Continuum and Magnetogram from 1997 to 2012, power spectra with peaks are calculated by using Fourier transform, respectively. A first peak of the power spectra is determined, and time intervals between nearest neighbor peaks are valued. The behavior of the packing exponents represented with time series are discribed in detail and discussed.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学理学部"},{"subitem_1522300295150":"en","subitem_1522300316516":"Faculty of Science University of the Ryukyus"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/27754"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0286-9640"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250774"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学理学部紀要"},{"subitem_1522650068558":"en","subitem_1522650091861":"BULLETIN OF THE FACULTY OF SCIENCE UNIVERSITY OF THE RYUKYUS"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2013-09-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"96","bibliographicPageEnd":"24","bibliographicPageStart":"1"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"No96p001.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2007565/files/No96p001.pdf"},"version_id":"6fbc95a7-0be8-4889-8af1-816c0d2f756c"}]},"item_title":"太陽活動極小期における太陽面上のマグネトグラム時系列の特徴","item_type_id":"15","owner":"1","path":["1642837987823","1642838406414"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-10-10"},"publish_date":"2013-10-10","publish_status":"0","recid":"2007565","relation_version_is_last":true,"title":["太陽活動極小期における太陽面上のマグネトグラム時系列の特徴"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T03:23:19.069482+00:00"}
