In this study distributed optic fiber has been used to measure both the Rayleigh and Brillouin frequency shift of two different sandstone core samples under controlled hydrostatic confining and pore pressure in the laboratory. The Berea sandstone cor

The noise power spectral density of the mesoscopic devices was measured at low temperatures with two homemade systems for low- and high-frequency ranges. By measuring the noise of the devices at finite bias voltages in the low-freqiency setup, we est

A system of numerical flow simulation with an automated mesh generator and parallelized solver was developed and applied to the flow-field inside an optical disc drive. In this simulation system, a uniformly spaced Cartesian grid is used to reduce ti

An intense, short-pulsed laser beam can accelerate a small flyer as fast as LEO (low earth orbit) satellite velocity. Using laser-accelerated flyers, we performed hyper-velocity impact tests as a simulation of orbital debris impact. Using a high-spee

We performed hyper-velocity impact tests that laser-accelerated aluminum flyer collided to carbon fiber reinforced plastics (CFRP) target. A short-pulsed intense laser beam can accelerate a small flyer as fast as LEO (low earth orbit) satellite veloc

We examined hyper-velocity impact tests for CFRP (Carbon Fiber Reinforced Plastics) laminates using laser accelerated multi-layered flyers. The multi-layered flyer consists of three layers; aluminum (Al), polyethylene (CH) and Al. The third layer of
