Commensurability of Measuring Instruments for Textile Science and Practice

Gniotek K., Kucharska-Kot J.

Fibres & Textiles in Eastern Europe

2004

Vol. 12, no. 2 (46)

86--89

This article describes a new feature of measuring instruments, designated as commensurability. The analysis of this feature has been based on linear and rank correlation, and the linear correlation coefficient and the Spearman coefficient have been accepted as its measure. Two examples of commensurability estimation are presented, one considering a case when both instruments measure the same physical quantity, and the second when they measure different physical quantities.

W artykule opisano nową cechę przyrządów pomiarowych, którą nazwano współmiernością. Analizę tej cechy oparto na korelacji liniowej i rangowej, a jako miarę liczbową zaproponowano współczynnik korelacji liniowej i współczynnik Spearmana. Podano dwa przykłady oceny współmierności dla przypadków, gdy badane przyrządy mierzą tę samą wielkość i różne wielkości fizyczne.

Exploration of univariate data in the textile metrology

Militky J., Meloun M.

Zeszyty Naukowe. Włókiennictwo / Politechnika Łódzka

2000

z. 58

The main aim of data analysis in textile metrology is the extraction of relevant information from measurements. This contribution is focused to most frequent task, i.e univariate data treatment based on the analysis of experimentally determined values Xi, i=1,...N. The system of exploratory data analysis based on concept of quantile estimation is proposed. The main part of this contribution is devoted to the description of several graphical tools for data summarization and exploration. Selected techniques are used for analysis of the strength of basalt fibers at small gauge length. The program package ADSTAT for realization of the above-mentioned techniques is briefly described.

The main aim of data analysis in textile metrology is the extraction of relevant information from measurements and creation of probability models. This contribution is focused to most frequent task, i.e univariate data treatment based on the analysis of experimentally determined values Xi, i=1,...N. The main part of this contribution is devoted to the description and camparison of data distribution with theoretical ones. Selected techniques are used for analysis of the strength of basalt fibers at small gauge length.
