This paper develops ordinal methods to test for changes in the relative academic performance of youth from high-income and low-income households. Applied to the NLSY79 and NLSY97 surveys, these ordinal methods show that the difference in academic achievement between youth from high and low-income households narrowed substantially between 1980 and 1997. In contrast, methods relying on the cardin...

This paper studies strict preference relations on product sets induced by “ordinal aggregation methods”. Such methods are interpreted here as performing paired comparisons of alternatives based on the “importance” of attributes favoring each element of the pair: alternative x will be preferred to alternative y if the attributes for which x is better than y are “more important” than the attribut...

Longitudinal heat conduction is an important parameter in the cryogenic field, especially in cryogenic heat exchangers. In the present work, the parasitic effect of tube wall longitudinal heat conduction on temperature measurement has been studied in cryogenic laminar hydrogen flow. The effects of various parameters such as wall cold end temperature, wall thermal conductivity, gas volumetric fl...

We address in this paper the problem of scoring alternatives when they are evaluated with respect to several criteria on a finite ordinal scale E. We show that in general, the ordinal scale E has to be refined or shrunk in order to be able to represent the preference of the decision maker by an aggregation operator belonging to the family of mean operators. The paper recalls previous theoretica...

It happens more and more often in decision aiding situations to be faced with ordinal or nominal information concerning the alternatives that are considered by a client/decision maker (hereafter we will use the term decision maker DM). By the term ordinal or nominal information we intend the fact that evaluation on attributes, descriptors, indexes, criteria etc. may be expressed on ordinal or n...

The impact of water shifts due to changes in posture has been reinvestigated for serum protein and calcium concentrations in a young, healthy population. We found that generaly accepted normal ranges for total serum protein, and to a lesser degree for total serum calcium, are not acceptable as a reference range for a hospitalized population that is predominantly in a supine position. Our data i...

The three-dimensional CMKF-D with only position measurements is extended to solve the radar target tracking problem with range-rate measurements, where the errors between range and range-rate measurements are correlated. Firstly, a pseudo measurement is constructed by the product of range and range-rate measurements to reduce the high nonlinearity of the range-rate measurements with respect to ...
