A processor for the fast wavelet transform is of the frequency sampling structure in architectural level. The fast wavelet transform owes its parallelism both to the frequency sampling structure and parallel tapping of a series of delay elements. Computational burden of the fast transform is hence independent of specific scale values in wavelets and the parallel processing of the fast transform is readily implemented for real-time applications. This point is quite different from the computation of wavelet transforms by convolution. We applied the fast wavelet transform to detecting detonation in a vehicle engine for precise real-time control of ignition advancement. The prototype wavelet for this experiment was the Gaussian wavelet (i.e. Gabor function) which is known to have the least spread both in time and in frequency. The number of complex multiplications needed to compute the fast wavelet transform over 51 scales is 714 in this experiment, which is less than one tenth of that required for the convolution method. Experimental results have shown that detonation is successfully detected from the acoustic vibration signal picked up by a single knock sensor embedded in the outer wall of a V/8 engine and is discriminated from other environmental mechanical vibrations.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "6286", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "菊池, 久和"}]}, {"nameIdentifiers": [{"nameIdentifier": "6287", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "渡辺, 弘道"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Institute of Electronics, Information and Communication Engineers"}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.ieice.org/jpn/trans_online/", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "copyright©1992 IEICE"}]}, "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": "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": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Kikuchi, Hisakazu"}], "nameIdentifiers": [{"nameIdentifier": "6281", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakashizuka, Makoto"}], "nameIdentifiers": [{"nameIdentifier": "6282", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Watanabe, Hiromichi"}], "nameIdentifiers": [{"nameIdentifier": "6283", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Watanabe, Satoru"}], "nameIdentifiers": [{"nameIdentifier": "6284", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tomisawa, Naoki"}], "nameIdentifiers": [{"nameIdentifier": "6285", "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": "e75-a_8_980.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": "e75-a_8_980.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/1930/files/e75-a_8_980.pdf"}, "version_id": "3814ac9c-4ffe-4f42-81a3-940e30dcd7e7"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "digital signal processing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "wavelets", "subitem_subject_scheme": "Other"}, {"subitem_subject": "signals and waves", "subitem_subject_scheme": "Other"}, {"subitem_subject": "acoustics", "subitem_subject_scheme": "Other"}]}, "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Fast Wavelet Transform and Its Application to Detecting Detonation", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Fast Wavelet Transform and Its Application to Detecting Detonation"}, {"subitem_title": "Fast Wavelet Transform and Its Application to Detecting Detonation", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/6490", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-07-16"}, "publish_date": "2008-07-16", "publish_status": "0", "recid": "1930", "relation": {}, "relation_version_is_last": true, "title": ["Fast Wavelet Transform and Its Application to Detecting Detonation"], "weko_shared_id": null}
