Mathematical theory of measurement problems: applications. Determination and adjustment of calibration intervals for means of measurement

Issue: KIPiS 2020 #5

The experience of calibration intervals determination shows that there are several factors that may affect the results. In the following article professor S. Levin provides the detailed information concerning these factors, and demonstrates the results of the main methodological aspects of the compositional approach to determine the calibration intervals.

 
Mathematical theory of measurement problems: applications. «Cosmically jerk» or rang inversion — the reason for «dead end» in cosmology

Issue: KIPiS 2020 #4

Accumulated experience in measuring instruments calibration taking into account inadequacy errors has made it possible to identify an essential factor of the «dead end» in cosmology. But strictly speaking there is no «dead end». There is usual discordance of mathematical models built basing on measurement data from various sources aggravated by violations of the conditions for statistical methods applicability when inadequacy errors of mathematical models can be no longer neglected.

 
Mathematical theory of measurement problems: applications. Catastrophically phenomenon «1985-1986», Risk management and ISO/IEC 17025–2019

Issue: KIPiS 2020 #3

On September 1, 2019 ISO/IEC 17025–2019 came into force. This standard describes the general competence requirements for testing and calibration laboratories. In the present article professor S. Levin unites catastrophic historical facts, risk management analysis and this standard and considers whether this interconnection is actually possible and correct.

 
Mathematical theory of measurement problems: applications. Inadequacy and reliability in metrology

Issue: KIPiS 2020 #2

Metrology is a fundamental science about the methods and means to reflect the physical objects nature with the help of mathematical models. And for metrology the problem of inadequacy has always been the central one. The present article by Professor S. Levin keeps very interesting centuries-old history facts that will help you to better understand this problem.

 
Mathematical theory of measurement problems: applications. Once again about «reliability» in metrology

Issue: KIPiS 2019 #5

The latest issue of «Chief metrologist» magazine for 2018 contains rather interesting discussion concerning the use of «reliability» term in metrology. Although a wide range of regulatory documents keep this term can it be considered correct in its full meaning? Present article by professor Levin S. is dedicated to this matter and will inform you of more details upon this term use.
