However, in this paper we propose improving the time-domain response of a conventional thermistor using a signal processing technique composed of a series of first-order high-pass filters which is known as the natural observation system. We considered the rise time of the thermistor in response to a step temperature change to effect correction for the measurement of the ejection fraction. The coefficients of the natural observation system were calculated by minimizing the square error between the step-response signal of the thermistor and the band-limited reference signal. In an experiment using a model ventricle, the thermodilution curve obtained from a conventional thermistor was improved using the proposed technique, thus enabling successful measurement of the ejection fraction of the ventricles.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u96fb\u5b50\u60c5\u5831\u901a\u4fe1\u5b66\u4f1a"}]}, "item_5_relation_31": {"attribute_name": "\u7570\u7248\u3067\u3042\u308b", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.ieice.org/jpn/trans_online/index.html", "subitem_relation_type_select": "URI"}}, {"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110003215808", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "copyright@1994 IEICE"}, {"subitem_rights": "\u672c\u6587\u30c7\u30fc\u30bf\u306f\u5b66\u5354\u4f1a\u306e\u8a31\u8afe\u306b\u57fa\u3065\u304dCiNii\u304b\u3089\u8907\u88fd\u3057\u305f\u3082\u306e\u3067\u3042\u308b"}]}, "item_5_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10826239", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09168508", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Hori, Jun\u0027ichi"}], "nameIdentifiers": [{"nameIdentifier": "6251", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Saitoh, Yoshiaki"}], "nameIdentifiers": [{"nameIdentifier": "6252", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kiryu, Tohru"}], "nameIdentifiers": [{"nameIdentifier": "6253", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "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": "110003215808.pdf", "filesize": [{"value": "989.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 989200.0, "url": {"label": "110003215808.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1924/files/110003215808.pdf"}, "version_id": "63fa0405-147f-4cfd-98a0-9740a6580054"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Improvement of the Time-Domain Response of a Thermodilution Sensor by the Natural Observation System (Special Section on Signal Processing and System Theory)", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Improvement of the Time-Domain Response of a Thermodilution Sensor by the Natural Observation System (Special Section on Signal Processing and System Theory)"}, {"subitem_title": "Improvement of the Time-Domain Response of a Thermodilution Sensor by the Natural Observation System (Special Section on Signal Processing and System Theory)", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["453/454", "423/424/425"], "permalink_uri": "http://hdl.handle.net/10191/20222", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2012-10-24"}, "publish_date": "2012-10-24", "publish_status": "0", "recid": "1924", "relation": {}, "relation_version_is_last": true, "title": ["Improvement of the Time-Domain Response of a Thermodilution Sensor by the Natural Observation System (Special Section on Signal Processing and System Theory)"], "weko_shared_id": null}
