Resolving Scale Ambiguity Via XSlit Aspect Ratio Analysis [PDF]
, 2015 In perspective cameras, images of a frontal-parallel 3D object preserve its aspect ratio invariant to its depth. Such an invariance is useful in photography but is unique to perspective projection.

On the Mass-to-Light Ratio of Large Scale Structure [PDF]
, 2004 We examine the dependence of the mass-to-light (M/L) ratio of large-scale structure on cosmological parameters, in models that are constrained to match observations of the projected galaxy correlation function w(rp). For a sequence of cosmological models

Gender differences in loudness perception may be linguistically influenced
Mechanical Engineering Journal, 2019 Previous studies have reported gender differences in loudness perception. To clarify factors that affect loudness perception of men and women, so that differences in their processing of auditory stimuli might be revealed, we conducted four experiments ...
