Frequency-domain immersion technique for accurate optical property measurements of turbid media

Optics Letters, 1999
We demonstrate that absorption coefficient micro(a) and reduced scattering coefficient micro(s)(?) of a small turbid object can be measured to high accuracy with a frequency-domain immersion technique. For this technique the sample is immersed in a calibrated scattering medium and the optical properties are obtained from a differential measurement ...

Extraction and analysis on oil immersed paper’s obscured low frequency polarization based on Frequency Domain Spectrum

2019 IEEE 20th International Conference on Dielectric Liquids (ICDL), 2019
Frequency domain spectrum is regarded as a reflection of insulation material’s dielectric process such as conductance and polarization which provides non-destructive insulation diagnosis on power equipment nowadays. Theories and explanations on this method are controversial with plenty of arguments, which limits its further application.

High frequency limiting virtual-mass coefficients of heaving half-immersed spheres

Journal of Fluid Mechanics, 1977
High frequency surface waves are generated by the forced heaving of either two half-immersed spheres in infinite water or by a half-immersed sphere in a hemispherical lake. The virtual-mass coefficients can be found, to leading order, in terms of wave-free limit potentials.

The frequency of occurrence and severity of side-effects of immersion virtual reality.

Aviation, space, and environmental medicine, 1994
Virtual reality (VR) has become increasingly well-known over the last few years. However, little is known about the side-effects of prolonged immersion in VR. This study set out to investigate the frequency of occurrence and severity of side-effects of using an immersion VR system.
