20.500.12556/RUL-171062 Evaluation of uncertainty associated with totalisation of time-sampled data in gas quantity and energy measurements The measurement uncertainty attributed to gas quantity and energy measurements includes among others a contribution for the calculation of the total/average from time-sampled data. The aim of this paper is to establish a procedure for evaluation of this component of uncertainty, which considers contributions related to deterministic and random variations of the input data. The principal steps of the proposed procedure are (i) separation of deterministic and random components via time-domain filtering, (ii) evaluation of uncertainty associated with deterministic component by the decimation method and (iii) evaluation of uncertainty associated with random component by statistical analysis. The paper presents this evaluation procedure for a test case of time-sampled data of the superior calorific value. gas energy measurements time-sampled data deterministic variations random variations time-domain filtering measurement uncertainty true false true Angleški jezik Ni določen Članek v reviji 2025-07-30 14:14:05 2025-07-30 14:14:07 2025-07-31 04:10:52 0000-00-00 00:00:00 2025 0 0 4 str. suppl., art. 101572 Vol. 38 May 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.317:533 2665-9174 10.1016/j.measen.2024.101572 234750979 Kutin_Evaluation_of_uncertainty.pdf Kutin_Evaluation_of_uncertainty.pdf 1 29CB46F3AE9920B80F04A1FCC6CB090A 4ee83a0a4d290006501b1ca44324e983f6db875d4e90c4181eccb7a053098c39 f78c033c-6d3e-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=213795 https://www.sciencedirect.com/science/article/pii/S2665917424005488 1 a67cb7a9-6d3e-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=213794 Fakulteta za strojništvo 0 0 0
