TS-MUWSN: Time synchronization for mobile underwater sensor networks [PDF]

, 2016
Time synchronization is an important, yet challenging, problem in underwater sensor networks (UWSNs). This challenge can be attributed to: 1) messaging timestamping; 2) node mobility; and 3) Doppler scale effect. To mitigate these problems, we present an

The energetic basis of acoustic communication [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2010
Animals produce a tremendous diversity of sounds for communication to perform life's basic functions, from courtship and parental care to defence and foraging. Explaining this diversity in sound production is important for understanding the ecology, evolution and behaviour of species.

Ship Radiated Noise Recognition Using Resonance-Based Sparse Signal Decomposition

Shock and Vibration, 2017
Under the complex oceanic environment, robust and effective feature extraction is the key issue of ship radiated noise recognition. Since traditional feature extraction methods are susceptible to the inevitable environmental noise, the type of vessels ...

Auditory communication in domestic dogs: vocal signalling in the extended social environment of a companion animal [PDF]

, 2014
Domestic dogs produce a range of vocalisations, including barks, growls, and whimpers, which are shared with other canid species. The source–filter model of vocal production can be used as a theoretical and applied framework to explain how and why the ...

Underwater TDOA Acoustical Location Based on Majorization-Minimization Optimization

Sensors, 2020
Underwater acoustic localization is a useful technique applied to any military and civilian applications. Among the range-based underwater acoustic localization methods, the time difference of arrival (TDOA) has received much attention because it is easy

A Low-Cost Robust Distributed Linearly Constrained Beamformer for Wireless Acoustic Sensor Networks with Arbitrary Topology

, 2018
We propose a new robust distributed linearly constrained beamformer which utilizes a set of linear equality constraints to reduce the cross power spectral density matrix to a block-diagonal form.

CONTRAST BETWEEN LIGHT AND SOUND WAVELENGTHS PERCEIVED BY HUMANS\ud \ud [PDF]

, 2008
A quantitative interrelation between the physical parameters of electromagnetic and acoustic waves perceived by the sight and hearing organs of a human has been discovered. It is shown that visible light wavelengths can be correlated with the range most
