Remote Inspection of Internal Delamination in Wind Turbine Blades using Continuous Line Laser Scanning ThermographyInternational Journal of Precision Engineering and Manufacturing-Green Technology - Tập 7 - Trang 699-712 - 2020
Soonkyu Hwang, Yun-Kyu An, Jinyeol Yang, Hoon Sohn
This study proposes a continuous line laser scanning thermography (CLLST) system for remote inspection of internal delamination in wind turbine blades. The CLLST system offers the following advantages: (1) remote delamination inspection can be achieved by mechanically scanning a line laser beam and simultaneously capturing the corresponding thermal waves in nondestructive and noncontact manners; (...... hiện toàn bộ

Intense pulsed light (IPL) sintering or annealing technology has attracted tremendous attention from many researchers and a variety of industries owing to its unique features. In IPL process, the pulsed white flash-light from xenon lamp is irradiated on the target materials and converts it to the desired conductive layer. The IPL process is ambient condition and room temperature process. The irrad...... hiện toàn bộ
Development of Multi-layer Tubular Vascular Scaffold to Enhance Compliance by Exhibiting a Negative Poisson’s RatioInternational Journal of Precision Engineering and Manufacturing-Green Technology - Tập 8 - Trang 841-853 - 2021

Synthetic small diameter vascular grafts frequently fail owing to intimal hyperplasia, results from mismatched compliance between the vascular graft and native vessels. A vascular graft with a negative Poisson's ratio (NPR, materials expand transversely when pulled axially) was suggested to enhance compliance. We produced a three-layer tubular vascular scaffold with NRP properties. The luminal sid...... hiện toàn bộ
Recent Progress in Strain-Engineered Stretchable ConstructsInternational Journal of Precision Engineering and Manufacturing-Green Technology - - Trang 1-31 - 2023

2D hall sensor array for measuring the position of a magnet matrixInternational Journal of Precision Engineering and Manufacturing-Green Technology - Tập 1 - Trang 125-129 - 2014
Hyeong Joon Ahn, Kyoung Rock Kim
Hall sensor array is used to measure the position of a magnet array and needs compensation of errors caused by manufacturing tolerances as well as harmonic components of the magnetic flux of the magnet array. This paper presents a 2D hall sensor array to measure the position of a magnet matrix by filtering harmonic components. First, 1D sensor array to filter out arbitrary number of harmonic signa...... hiện toàn bộ
On-line Error-Matching Measurement and Compensation Method for a Precision Machining Production LineInternational Journal of Precision Engineering and Manufacturing-Green Technology - Tập 9 - Trang 493-505 - 2021

When producing a matching part for good mating with its counterpart (assembly part), good matching accuracy between the matching part and assembly part is highly required. The matching errors are influenced by not only the errors of the matching part but also the errors of the assembly part. Because the errors of an assembly part could be different from others, it is very difficult to have very go...... hiện toàn bộ
