An Information Entropy-Based Sensitivity Analysis of Radar Sensing of Rough Surface

open access: yesRemote Sensing, 2018
We apply Shannon entropy, an information content measure, in sensitivity analysis (SA), stemming from the fact that the essence of SA is to preserve the maximum information content of the parameters of interest that are inverted from the radar response ...

Numerical simulation of the backscattering of pressure waves from a bubble interface

open access: yesNihon Kikai Gakkai ronbunshu, 2015
The direct numerical simulations are conducted for the backscattering of incident pressure waves from a bubble with the ghost fluid method in order to understand the formation of secondary cavitation in the high intensity focused ultrasound (HIFU). It is

Spray-Dried Infant Formula Emulsion Stability as Affected by Pre-Heat Treatment and Total Solids Content of the Feed

open access: yesFoods, 2022
Pre-spray-drying processing may affect stability after reconstitution of emulsion-based powders, such as infant formulas. This study aimed to evaluate the effects of pasteurization temperature and total solids (TS) of the feed on the stability of the ...
