In order to evaluate seismic safety of piping systems with locally wall thinning by LDI, hybrid tests have been conducted incorporating a numerical analysis of whole s ystem with a loading test of elbow model. Seismic performance effects of wall thinning elbow were clarified by comparing three cases of different thickness elbow model s such as no defect, 50% thinning and 75% thinning. By these results, the almost same hystereses of the non-linear load displacement relations were obtained and the dam ages o...

In this study, the new Positive Contrast (PC) method was proposed to emphasize the tumors in MRI images. If the object includes magnetic particles such as S PIO(Super Paramagnetic Iron Oxide), the dark image is obtained because of the MRI's distorted magnetic field by the magnetic particles. This effect appears as the shift of peak position in K-space calculated from the Fourier transform of the sub-area of the MRI images. The tumor-emphasized MRI images were obta ined by selecting only the sub-areas that ...
