The thermodynamic temperature of the point inflection melting transition Re-C, Pt-C and Co-C eutectics has been determined to be 2747.84 ± 0.35 K, 2011.43 0.18 K 1597.39 0.13 respectively, freezing Cu 1357.80 0.08 where symbol represents 95% coverage. These results are best consensus estimates obtained from measurements made using various spectroradiometric primary thermometry techniques by nine different national metrology institutes. good agreement between institutes suggests that...
The eutectic alloys rhenium–carbon, platinum–carbon and cobalt–carbon have been proposed as reference standards for thermometry, with temperature uncertainty values specified within the mise en pratique of definition kelvin. These investigated in a collaboration eleven national measurement institutes laboratories. Published results reported point-of-inflection melting curve extremely low uncertainties. However, to be considered it is necessary stipulate what phenomenon value has ascribed to;...
The hyperspectral imager of the HISUI (Hyperspectral Imager Suite) project will be deployed and operated in International Space Station (ISS) Japanese Experiment Module-Exposed Facility (JEM-EF) FY2018. pre-launch calibration is conducted using a large integrating sphere traceable to SI, after launch, onboard carried out unit including lamp. vicarious over dry lake sites located both northern hemisphere southern hemisphere, we may also use automated facilities due effects orbital...
The time difference between coordinated universal (UTC) and a hydrogen maser, which is master oscillator for the local realization of UTC at National Metrology Institute Japan (NMIJ), has been predicted by using one deep learning techniques called one-dimensional convolutional neural network (1D-CNN). Regarding prediction result obtained 1D-CNN, we have observed improvement in accuracy compared with that Kalman filter. Although more investigations are required to conclude 1D-CNN can work as...
The next Japanese earth observing hyperspectral/multispectral imager mission, the HISUI (Hyper-spectral Imager SUIte) is currently underway. In order to guarantee hyperspectral images with a high spatial and wavelength resolution, it necessary evaluate difference of spectral sensitivities among detector devices arrayed twodimensionally correct misregistrations effect stray light. Since there are tens thousands detectors in two-dimensional-array sensor, they have be evaluated parallel,...

However, there are tens thousands detectors in hyperspectral so they have be evaluated parallel by special technique. Therefore, a light-source system which has radiance uniformity widely tunable wavelengthrange required...
Abstract We investigated the nanoionics-based neuromorphic function of Pt/Ti 0.96 Co 0.04 O 2− δ /Pt multilayers with a cross-point structure prepared by RF magnetron sputtering. This multilayer exhibits electro-ion mixed conduction and nonlinear current–voltage characteristic based on Schottky barrier between Pt Ti layers. When low electrical pulse 0.8 V was applied short interval time 14 s, current modulation corresponding to long-term memorization (LTM) observed, though response at long...
Abstract This article describes a preliminary study verifying the applicability of dual-wavelength reflectance-ratio (DWR) method to emissivity-free radiation thermometry for electromagnetically levitated high-temperature liquid metals. To establish measurement technique, DWR was applied inductively heated solid spherical Cu and Ni samples. Regardless differences in sample emissivity values, temperature determined using agreed within 20 K with thermocouple. It found that temperatures...
A new method to estimate the uncertainty due non-linearity is described on n = 3 scheme basis. The expression of mathematically derived applying random walk method. simple and requires only temperatures fixed points a relative value for each flux-doubling from measurement. We also present an example method, in which temperature measurement by radiation thermometer calculated basis
The earth-observing hyperspectral imager, HISUI (Hyper-spectral Imager SUIte), which is currently under development, has a wide spectral range from 0.4 μm to 2.5 μm, and the radiance of copper point insufficient for sensor calibration in wavelength shorter than 0.55 μm.
