Measurement, 2013
Abstract In the past, ratio scales have been a highly controversial issue between physicists and psychologists as regards the need for an empirical addition operation in order to attain them. This aspect is critical since such an operation is often unavailable in psychophysical experiments, as it is in physics, due to its intensive properties.

Alternative Power Laws for Ratio Scaling
Psychometrika, 1966To take account of the observed lack of fit of the power law near thresh-old intensities, two different modifications of the power law have been proposed by various investigators. In this paper, both of these two laws are derived as a special case of a generalized power function for ratio scaling.

Scale ratios, statistical symmetries and intermittency
Europhysics Letters (EPL), 1998Existence (or lack) of preferred scale has largely been used as a useful guide to investigate statistics of stochastic extended systems. In particular, widespread use of power laws in literature actually comes from the fact that these are the only single scale functions pertaining to systems relying on no preferred scale.

Scale ratio ICP for 3D point clouds with different scales
2013 IEEE International Conference on Image Processing, 2013In this paper we propose a method for matching the scales of 3D point clouds. 3D point sets of the same scene obtained by 3D reconstruction techniques usually differ in scale. To match scales, we estimate the ratio of scales of two given 3D point clouds.

CROWN RATIO INFLUENCES ALLOMETRIC SCALING IN TREES
Ecology, 2006Allometric theories suggest that the size and shape of organisms follow universal rules, with a tendency toward quarter-power scaling. In woody plants, however, structure is influenced by branch death and shedding, which leads to decreasing crown ratios, accumulation of heartwood, and stem and branch tapering.

The Arithmetic Teacher, 1977
My mathematics class was a high ability, sixth-grade group who understood ratio and scale, but, at the start of the project described here, needed practical exercises in using these skills. The need for practice in applying the concepts of ratio and scale suggested the use of architectural floor plans.

Micko's “Halo”-Model for Multidimensional Ratio Scaling
Psychometrika, 1975It is argued that (1) the halo-model of Micko is probably too restrictive to fit empirical data, (2) the model misrepresents unrelated percepts as bipolar structures, (3) all variations will probably be interpreted as qualitative, (4) the model requires all dimensions to be bipolar, (5) interpretations of orthogonality of factors and of factor loadings
