Effect of cosmic rays irradiation on the phase change characteristics of an on-orbit fixed point

European Physical Journal C: Particles and Fields, 2023
Using the phase change characteristics of fixed points to trace the temperature of a spaceborne calibration blackbody is an important technical means to carry out the high-precision on-orbit calibration of thermal infrared remote sensors.

Selection and Treatment of Data for Radiocarbon Calibration: An Update to the International Calibration (IntCal) Criteria [PDF]

, 2013
High-quality data from appropriate archives are needed for the continuing improvement of radiocarbon calibration curves. We discuss here the basic assumptions behind 14C dating that necessitate calibration and the relative strengths and weaknesses of ...

Preliminary Selection and Characterization of Pseudo-Invariant Calibration Sites in Northwest China

Remote Sensing, 2020
Pseudo-invariant calibration sites (PICS) have been used for the radiometric calibration and stability monitoring of satellite optical sensors. Several stable PICS, such as those in the Sahara Desert in North Africa, were selected for the vicarious ...

Save the "THRU" in the A.N.A. calibration [PDF]

, 1992
The conventional network analyzer (NWA) two-port calibration procedures require a standard thru line to be connected between the ports. Unfortunately in many applications, for example when measuring MMIC or on-wafer devices with not aligned ports, a ...

Calibration of Pre-trained Transformers [PDF]

Conference on Empirical Methods in Natural Language Processing, 2020
Pre-trained Transformers are now ubiquitous in natural language processing, but despite their high end-task performance, little is known empirically about whether they are calibrated.

SHCal20 Southern Hemisphere Calibration, 0–55,000 Years cal BP

Radiocarbon: An International Journal of Cosmogenic Isotope Research, 2020
Early researchers of radiocarbon levels in Southern Hemisphere tree rings identified a variable North-South hemispheric offset, necessitating construction of a separate radiocarbon calibration curve for the South.

A simple NWA calibration algorithm based on a transfer standard [PDF]

, 1997
A new two-port network analyzer (NWA) calibration technique is here presented. It uses a single two-port transfer standard plus a known reflectance to perform the calibration process.
