Deriving shallow-water sediment properties using post-stack acoustic impedance inversion
, 2015 In contrast to the use of marine seismic reflection techniques for reservoir-scale applications, where seismic inversion for quantitative sediment analysis is common, shallow-water, very-high-resolution seismic reflection data are seldom used for more ...

Bayesian identification of acoustic impedance in treated ducts.
Journal of the Acoustical Society of America, 2015 The noise reduction of a liner placed in the nacelle of a turbofan engine is still difficult to predict due to the lack of knowledge of its acoustic impedance that depends on grazing flow profile, mode order, and sound pressure level. An eduction method,

Electric Field Driven Soft Morphing Matter
Advanced Materials, EarlyView.This study presents soft morphing matter robots that exhibit extremely high morphological adaptability and complex multimodal electric field response. They can undergo large, controlled body deformation and show complex locomotion on different terrains under the manipulation of external electric fields, making a significant step beyond current ...
