Emissivity of aluminium and its importance for radiometric measurement
In the article, the authors analyse features of aluminium, which are important for the noncontact measurement of the temperature. This study is based on the results of experiments, which were carried out at foreign research institutes. Rising interest of the industry in contactless measurement of foamy aluminium profiles during their production was the motivation for this article.
متن کاملCalibration and Measurement Uncertainty Estimation of Radiometric Data: Preprint
Evaluating the performance of photovoltaic cells, modules, and arrays that form large solar deployments relies on accurate measurements of the available solar resource. Therefore, determining the accuracy of these solar radiation measurements provides a better understanding of investment risks. This becomes especially important as deployment size and investment costs grow to hundreds of million...
متن کاملRadiometric measurement of metabolic activity of Mycobacterium lepraemurium.
A sensitive and nondestructive radiometric method has been applied to the detection of metabolism of Mycobacterium lepraemurium, as a model for the study of the metabolism and substrate requirements of M. leprae. The method is based on the measurement of the (14)CO(2) produced through the bacterial conversion of [U-(14)C]acetate or [U-(14)C]glycerol by 7 x 10(9) bacteria suspended in 10 ml of e...
متن کاملRadiometric and Photometric Concepts Based on Measurement Techniques
The value of the fundamental quality in radiometry, the watt, is presently realized by electrical substitution in which the temperature produced in a blackened material due to absorption of radiant energy is balanced against that produced by electrical energy whose current and voltage can accurately be measured. A new method to measure optical radiation is being explored by the National Bureau ...
متن کاملThe Axioms of Quantity and the Theory of Measurement
Otto Ludwig Ho lder (born, Stuttgart, 1859; died, Leipzig, 1937) was professor of mathematics at the University of Leipzig (Ho lder, 1972) when he published the paper here translated into English. Today, Ho lder is remembered in mathematics for a variety of results, but he is of significance to readers of this journal because of Ho lder's theorem. This theorem occupies a central place in modern...
