The traveling wave representation of a vibrating system is discussed. Delay times and amplitude coefficients are considered to be the characterizing parameters, not only in the nondispersive wave propagation system but also in the dispersive case, if group delay time is defined. Three kinds of correlation method, such as, the correlation envelope method, the squared signal correlation method and the M-sequence correlation method are proposed to measure the group delay time and wave intensity. The acoustic wave propagation as an example of nondispersive case and the flexural wave propagation as a dispersive case are described and typical measured correlation functions are illustrated.", "subitem_description_type": "Other"}]}, "item_9_description_32": {"attribute_name": "資料番号", "attribute_value_mlt": [{"subitem_description": "資料番号: SA2400750000", "subitem_description_type": "Other"}]}, "item_9_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "東京大学宇宙航空研究所"}]}, "item_9_publisher_9": {"attribute_name": "出版者（英）", "attribute_value_mlt": [{"subitem_publisher": "Institute of Space and Aeronautical Science,University of Tokyo"}]}, "item_9_source_id_21": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0372-1418", "subitem_source_identifier_type": "ISSN"}]}, "item_9_source_id_24": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00675986", "subitem_source_identifier_type": "NCID"}]}, "item_9_text_34": {"attribute_name": "メタデータ提供者", "attribute_value_mlt": [{"subitem_text_value": "メタデータ提供者: ISASNII"}]}, "item_9_text_35": {"attribute_name": "JAXAカテゴリ", "attribute_value_mlt": [{"subitem_text_value": "JAXAカテゴリ: 宇宙科学研究所"}]}, "item_9_text_43": {"attribute_name": "DSpaceコレクション番号", "attribute_value_mlt": [{"subitem_text_value": "DSpaceコレクション番号: 6"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "AOSHIMA, Nobuharu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "419585", "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": "2020-01-24"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "SA2400750.pdf", "filesize": [{"value": "1.9 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1900000.0, "url": {"label": "SA2400750.pdf", "url": "https://jaxa.repo.nii.ac.jp/record/34426/files/SA2400750.pdf"}, "version_id": "900a2b9a-6c9d-451d-8b11-ed28746ef53b"}]}, "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": "Measurement of the Wave Propagation by Correlation Techniques", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Measurement of the Wave Propagation by Correlation Techniques", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["1890", "1992"], "permalink_uri": "https://jaxa.repo.nii.ac.jp/records/34426", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-03-26"}, "publish_date": "2015-03-26", "publish_status": "0", "recid": "34426", "relation": {}, "relation_version_is_last": true, "title": ["Measurement of the Wave Propagation by Correlation Techniques"], "weko_shared_id": -1}
