Interval and Ratio Scaling of Spectral Audio Descriptors
Frontiers in Psychology, 2022 Two experiments were conducted for the derivation of psychophysical scales of the following audio descriptors: spectral centroid, spectral spread, spectral skewness, odd-to-even harmonic ratio, spectral deviation, and spectral slope. The stimulus sets of

Probing the Symmetry Energy with the Spectral Pion Ratio [PDF]
Physical Review Letters, 2021 Many neutron star (NS) properties, such as the proton fraction within a NS, reflect the symmetry energy contributions to the Equation of State that dominate when neutron and proton densities differ strongly. To constrain these contributions at supra-saturation densities, we measure the spectra of charged pions produced by colliding rare isotope tin (Sn)

Damping-ratio measurements by the spectral-ratio method [PDF]
Canadian Geotechnical Journal, 2006 In this paper, bender elements are used as sensors to measure the damping ratio of soil by the spectral-ratio method. The results of numerical and physical experiments suggest that adequate measurement precision can be achieved by reducing the two types of inherent biases arising from (i) the near-field effect and (ii) the different transfer functions ...

A review on microtremor H/V spectral ratio method
地球与行星物理论评, 2021 The microtremor H/V spectral ratio is the ratio of the horizontal component to the vertical component of the ambient seismic noise at different frequencies, recorded at the earth surface.

Spectral Classification from Ratio Spectra [PDF]
Publications of the Astronomical Society of the Pacific, 1959 The classification of stars according to their spectral characteristics provides one of the principal working tools of the astronomer. A fundamental system of spectral classification is that of W. W. Morgan and P. C. Keenan. This system utilizes the photographic region of the spectrum from λ 3800 to λ 4900.

Thermal infrared spectroscopy of Europa and Callisto [PDF]
, 2000 The trailing hemispheres of Europa and Callisto were observed at 9–13 μm, and a spectrum of Europa with better spectral resolution and a better signal-to-noise ratio than was previously possible has been derived.
