Site amplification factors at period ranges of 0.1-0.2, 0.2-0.3, 0.3-0.5, 0.5-1, 1-2, and 2-10 s were determined for 27 stations of KiKnet and K-NET in and around the source area of the 2008 Iwate-Miyagi Nairiku earthquake. The ratio of the geometric mean values of the two maximum horizontal amplitudes of acceleration and velocity at the uphole to that at the downhole is considered as the ampli...

Abstract We present detailed experimental results with cryogenic Yb:YLF gain media in rod-geometry. have comparatively investigated continuous-wave (cw) lasing and regenerative amplification performance under different conditions. In the cw experiments effect of crystal doping, laser cavity geometry pump wavelength on were explored. Regenerative behavior was analyzed role depolarization losses ...

Amplification factors are often estimated using empirical methods based on earthquake ground motion; however, especially in low-seismicity urban areas, recording a statistically representative number of high-quality signals may take years. Hence, the attempts to use ambient vibration instead have progressed. This includes development hybrid site-to-reference spectral ratio (SSRh) method that co...

We have calculated and plotted the apparent permeability demagnetization factor of single magnetic wires. also confirmed accuracy analytical formula for conversion between factor. show that, as regards wire geometry, effective from inductance does not provide a good estimate permeability, but that it is close to amplification induction sensors. extend concept array. This will allow us design mu...
