These coefficients are computed for the different positions of the seam on the ball. The effect of this position and the rotation speed of the ball on the orbit are investigated. From the computations, we obtain numerically the \"irregular change of the orbit\" which is the most remarkable feature of the knuckleball. Also we find this feature appears even if the ball rotates several times per second suggesting the potential of the knuckleball with rifle spin which may be easier to throw than the ordinal knuckleball.","subitem_description_type":"Other"}]},"item_11_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"70892","nameIdentifierScheme":"WEKO"}],"names":[{"name":"デンボ, カナコ"}]},{"nameIdentifiers":[{"nameIdentifier":"70893","nameIdentifierScheme":"WEKO"}],"names":[{"name":"カワムラ, テツヤ"}]}]},"item_11_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"お茶の水女子大学"}]},"item_11_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00033958","subitem_source_identifier_type":"NCID"}]},"item_11_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00298190","subitem_source_identifier_type":"ISSN"}]},"item_11_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"400","subitem_subject_scheme":"NDC"}]},"item_11_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"758325 bytes"}]},"item_11_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"紀要論文"}]},"item_11_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper"}]},"item_11_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_11_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"03"}]},"item_11_text_79":{"attribute_name":"所属","attribute_value_mlt":[{"subitem_text_value":"Research Institute of Systems Planning"},{"subitem_text_value":"Ochanomizu University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Denbo, Kanako"}],"nameIdentifiers":[{"nameIdentifier":"70890","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawamura, Tetuya"}],"nameIdentifiers":[{"nameIdentifier":"70891","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":"2018-04-19"}],"displaytype":"detail","filename":"KJ00004830799.pdf","filesize":[{"value":"758.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004830799.pdf","url":"https://teapot.lib.ocha.ac.jp/record/34634/files/KJ00004830799.pdf"},"version_id":"fa5bca10-067a-431d-8cc8-5f2ebbb9a3b5"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Numerical study of the movement of the knuckleball with rifle spin","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Numerical study of the movement of the knuckleball with rifle spin"}]},"item_type_id":"11","owner":"1","path":["682"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-30"},"publish_date":"2008-04-30","publish_status":"0","recid":"34634","relation_version_is_last":true,"title":["Numerical study of the movement of the knuckleball with rifle spin"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-12T05:39:00.787521+00:00"}
