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", "download_preview_message": "", "file_order": 0, "filename": "25_3_185-191.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1200000.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/20186", "pubdate": {"attribute_name": "公開日", "attribute_value": "2012-10-24"}, "publish_date": "2012-10-24", "publish_status": "0", "recid": "2741", "relation": {}, "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_shared_id": null}
