EMATs for Science and Industry: Noncontacting Ultrasonic Measurements
Masahiko Hirao,Hirotsugu Ogi +1 more
TL;DR: In this paper, the authors present a survey of EMAT techniques and their applications in the industrial domain, including on-line texture monitoring of steel sheets and in-situ monitoring of Dislocation Mobility.
Journal ArticleDOI
Distinguishing crystal-like amyloid fibrils and glass-like amorphous aggregates from their kinetics of formation
Yuichi Yoshimura,Yuxi Lin,Hisashi Yagi,Young-Ho Lee,Hiroki Kitayama,Kazumasa Sakurai,Masatomo So,Hirotsugu Ogi,Hironobu Naiki,Yuji Goto +9 more
TL;DR: By monitoring the kinetics of the formation of amyloid fibrils and glass-like amorphous aggregates, it is shown that solubility and supersaturation will be key factors for further understanding the aberrant aggregation of proteins.
Journal ArticleDOI
An SH-wave EMAT technique for gas pipeline inspection
Masahiko Hirao,Hirotsugu Ogi +1 more
TL;DR: In this paper, a periodic-permanent-magnet (PPM) EMAT is placed inside the pipe, which generates and receives the SH guided waves traveling in the circumferential direction with the axial polarization.
Journal ArticleDOI
Complete mode identification for resonance ultrasound spectroscopy.
TL;DR: This study adopts a laser-Doppler interferometer to measure the displacement-distribution patterns on a surface of the vibrating specimen mounted on pinducers and comparison of the measured displacement distributions with those computed permits us to correctly identify the measured resonance frequencies, leading to unmistakable determination of elastic constants.
