One of the practical difficulties of SHM is that usually a large area must be monitored using a limited number of sensors fixed at certain locations. And the sensor placement is a decisive contributor to the detection capability of SHM because measured signals are generally dependent on the location of a defect with respect to a sensor. In order to quantify the detection sensitivity more reasonably, this study proposes an analytical method based on a closed-form probability density function and a numerical method based on Monte-Carlo simulation to quantify the detection sensitivity, taking into account the randomness of sensor location. The effectiveness of the proposed detection sensitivity analysis model has been examined using simulated inspection signals of low frequency electromagnetic monitoring for detecting full circumferential pipe wall thinning.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u4e00\u6628\u65e5\u306eMeasurement\u8a8c\u306b\u7d9a\u304d\u3001\u7c73\u56fd\u975e\u7834\u58ca\u691c\u67fb\u5354\u4f1a\u306e\u5b66\u8853\u8ad6\u6587\u8a8c\u3067\u3042\u308bResearch in Nondestructive Evaluation\u8a8c\u306bA d &#8230; <\/p>\n","protected":false},"author":2,"featured_media":6555,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2,8,193,14],"tags":[143],"class_list":["post-6525","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-achievement","category-journal","category-rnde","category-student","tag-143"],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/web.tohoku.ac.jp\/yusa\/wp-content\/uploads\/2021\/01\/urnd20.v032.i01.jpeg?fit=555%2C793&ssl=1","_links":{"self":[{"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts\/6525","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/comments?post=6525"}],"version-history":[{"count":8,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts\/6525\/revisions"}],"predecessor-version":[{"id":6630,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/posts\/6525\/revisions\/6630"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/media\/6555"}],"wp:attachment":[{"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/media?parent=6525"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/categories?post=6525"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/web.tohoku.ac.jp\/yusa\/index.php\/wp-json\/wp\/v2\/tags?post=6525"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
