Uncertainty of the Kriss Low Frost-Point Humidity Generator
The KRISS low frost-point humidity generator (LFPG), was developed in 2006 for the frost-point range (−95 to −40)°C in order to extend calibration capabilities. In this paper, the evaluation of the generator’s un...

The New KRISS Low Frost-Point Humidity Generator
A new low frost-point humidity generator (LFPG) has been designed, and its performance has been tested, in order to extend the calibration capabilities to the low frost-point range at KRISS. The water vapor–ga...

Thermal Conductivity of Chalcogenide As2S3 Thin Films
In order to investigate the photo-induced thermal property changes in chalcogenide thin films, amorphous As 2 S 3 thin film samples, whose thicknesses are 0.5, 1.0, 2.0, and 4.0 μm, were prepared on silicon wafer...

One-Level, Two-Point Method for Estimation of Thermal Diffusivity by the Converging Thermal-Wave Technique
The thermal diffusivity of several kinds of metal sheets was measured by the converging thermal-wave technique. This is a typical technique which can obtain the in-plane thermal diffusivity by measurement of t...

Effect of the thickness of plasma-sprayed coating on bond strength and thermal fatigue characteristics
NiCrAlY bond coat and ZrO2–8 wt% Y2O3 top coat with various thicknesses were deposited on Hastelloy X by plasma spraying. Residual stress was calculated by the finite element method (FEM) to explain the variat...
