PSYCHOPHYSICAL LAW AND SCALING MODELS*

Psychophysical Scaling'"

their helpful criticisms of a preliminary draft of this chapter. A special word of thanks is due Dr. Stevens, u~ho, in addition to discovering seueral errors of fact and a nutnber of stylistic blunders, forced us to reconsider some of our views on various aspects of scaling. His comments coupled wzth our own misgivings resulted in a complete revision oj'the section on magnitude estimation and t...

Psychophysical Scaling of Sonification Mappings

We determined preferred data-to-display mappings by asking experiment participants directly and then examined the psychophysical scaling functions relating perceived data values to underlying acoustic parameters. Presently, we are extending and validating the scaled mappings in practical data interpretation tasks. The resulting scaling functions, in conjunction with the experimental paradigm de...

Scaling Law and Reduced Models for Epitaxially Strained Crystalline Films

A variational model for the epitaxial deposition of a film on a rigid substrate in the presence of a crystallographic misfit is studied. The scaling behavior of the minimal energy in terms of the volume of the film and the amplitude of the misfit is considered, and reduced models in the various regimes are derived by Γ-convergence methods. Depending on the relation between the thickness of the ...
