This paper presents a new approach. This is based on a block algorithm in which a signal is divided in time into blocks and time-varying parameters are estimated in each block. A locally quasi-stationary processing, which is proposed here, is the method to estimate the parameters of an AR (autoregressive) model more precisely. It is assumed that an AR model represents a surface EMG generation system. There have been many methods for the non-stationary analysis, for example, the synchronous averaging in stochastic approaches and the estimation methods of short-time power spectrum and system function by a locally stationary processing. However, the synchronous averaging method is restricted to the evoked responses of EEG or EMG and the locally stationary processing is not sufficient for essentially non-stationary signals. In this paper, AR parameters were estimated from the surface EMG of masseter muscle by the locally quasi-stationary processing and the results were compared with the parameters by the conventional locally stationary processing. There are non-stationary intervals around evoked response or onset of masticatory EMG. AR parameters are linear prediction coefficients, reflection coefficients and poles. As the results, the estimated characteristics of the time-varying parameters were reasonable in relation to the locus of lower jaw movement and the significant differences were showed in the non-stationary intervals.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"38787","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kiryu, Tohru"}]},{"nameIdentifiers":[{"nameIdentifier":"38788","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Iijima, Taizo"}]},{"nameIdentifiers":[{"nameIdentifier":"38789","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Saitoh, Yoshiaki"}]},{"nameIdentifiers":[{"nameIdentifier":"38790","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ishioka, Kiyoshi"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本ME学会"}]},"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":"AN00016981","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00213292","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"木竜, 徹"}],"nameIdentifiers":[{"nameIdentifier":"38783","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"飯島, 泰蔵"}],"nameIdentifiers":[{"nameIdentifier":"38784","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"斉藤, 義明"}],"nameIdentifiers":[{"nameIdentifier":"38785","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石岡, 靖"}],"nameIdentifiers":[{"nameIdentifier":"38786","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":"25_3_185-191.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"25_3_185-191.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2741/files/25_3_185-191.pdf"},"version_id":"f543bc48-20a1-4c34-ac66-9040e99eec82"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"局所準定常処理による運動時咀嚼筋筋電図の特徴づけ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"局所準定常処理による運動時咀嚼筋筋電図の特徴づけ"},{"subitem_title":"局所準定常処理による運動時咀嚼筋筋電図の特徴づけ","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-24"},"publish_date":"2012-10-24","publish_status":"0","recid":"2741","relation_version_is_last":true,"title":["局所準定常処理による運動時咀嚼筋筋電図の特徴づけ"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:35:58.667329+00:00"}
