RANKINGS AS ORDINAL SCALE MEASUREMENT RESULTS
Journal Title: Metrology and Measurement Systems - Year 2007, Vol 14, Issue 1
Abstract
Rankings (or preference relations, or weak orders) are sometimes considered to be non-empirical, non-objective, low-informative and, in principle, are not worthy to be titled measurements. A purpose of the paper is to demonstrate that the measurement result on the ordinal scale should be an entire (consensus) ranking of n objects ranked by m properties (or experts, or voters) in order of preference and the ranking is one of points of the weak orders space. The consensus relation that would give an integrative characterization of the initial rankings is one of strict (linear) order relations, which, in some sense, is nearest to every of the initial rankings. A recursive branch and bound measurement procedure for finding the consensus relation is described. An approach to consensus relation uncertainty assessment is discussed.

The Coulomb Blockade effect (CBE) is observed in double tunnel junctions where a small metallic cluster is precisely located between two outer electrodes. This electrically isolated nanocluster exhibits capacitances of a...
APPLICATION OF DIGITAL DITHER TO REDUCTION OF FEEDBACK D/A CONVERTERS INFLUENCE ON INTELLIGENT CYCLIC A/D CONVERTERS PERFORMANCE
The effect of termination of resolution growth, common for cyclic analogue-to-digital converters (CADCs) the, which appears after a definite (threshold) number of the conversion cycles, is investigated in the paper. The...
FORMAL DEFINITION AND PROPERTIES OF FEB-BASED ENOB OF INTELLIGENT CYCLIC ADC
The paper presents a new approach to the measurement of effective resolution (effective number of bits - ENOB) of the cyclic A/D converters (CADCs). The core idea of the approach is a direct measurement of ENOB using, as...
