V príspevku sa dáva dôraz na výhody prístupu vzorkovania z distribúcie výstupných veličín cez charakteristické funkcie založenom na distribúcii typu kopula vstupných veličín s marginálnymi distribúciami daného konvolučného typu. Proper uncertainty analysis in metrology frequently requires using model with a nonlinear measurement equations and non-trivial joint multivariate distribution of the input quantities. In the paper we emphasize the advantage of using the Characteristic Function Approach for sampling from the distribution of the output quantities, based on the joint copula-type distribution of the input quantities with given convolution-type marginal distributions.

The verification is done by using certified reference materials of ethanol in nitrogen in 4 concentration levels of ethanol. Here we offer an overview of steps, which are checking the traceability of measurement from the process of verification up to traceability of used reference material to SI unit of mass kg. Each single step is described and has its uncertainty budget URL Link na plný text Public work category AFC No. of Archival Copy 43627 Catal.org.

Navrhnutý je nový prístup pre určenie neznámej koncentrácie etanolu v zmesi plynov pri použití kalibračnej priamky, ktorú dostaneme modelovaním kalibračného experimentu ako modelu s chybami v premenných. The paper deals with the errors-in-variables (EIV) linear calibration of the gas mixture of ethanol in nitrogen with unknown concentration. Suggested is a new approach for determination the unknown values of the calibration line parameters obtained by modeling the calibration experiment as an EIV model Public work category AFC No. of Archival Copy 43931 Catal.org.
