Fractals in underwater acoustics [PDF]
, 1997 The concept of fractals and their applications for underwater acoustics are discussed. Waves scattering by a fractal surface is considered. Ray chaos in the case of waves propagation in inhomogeneous underwater waveguides is discussed.

Bistable Networks Enable Complex Shape Changes
Advanced Science, EarlyView.Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

Bubble acoustics: from whales to other worlds
, 2014 Gas bubbles in liquids have an extraordinary ability to interact with sound fields. They are potent generators, absorbers, and scatterers of sound, and can have a profound effect upon the sound speed (changing it on subsecond timescales by a factor of 2 ...

Adaptive interference suppression based on an invariant subspace of matrices matching for a horizontal array in underwater acoustics [PDF]
JASA Express LettersPassive detection of target-of-interest (TOI) within strong interferences poses a challenge. This paper introduces an adaptive interference suppression based on an invariant subspace of matrix matching. Assume that the TOI-bearing intervals are known. We

Estimating animal population density using passive acoustics [PDF]
, 2013 Reliable estimation of the size or density of wild animal populations is very important for effective wildlife management, conservation and ecology. Currently, the most widely used methods for obtaining such estimates involve either sighting animals from

Advanced Science, EarlyView.ABSTRACT Mechanophores with mechanochromic properties have attracted significant attention as force‐responsive materials for structural sensing. However, their applications remain mainly limited to qualitative force visualization, as direct and quantitative extraction of mechanical parameters such as stress and strain from mechanochromic responses has ...
