ARTMAP-FTR: A Neural Network For Fusion Target Recognition, With Application To Sonar Classification [PDF]

open access: yes, 1998
ART (Adaptive Resonance Theory) neural networks for fast, stable learning and prediction have been applied in a variety of areas. Applications include automatic mapping from satellite remote sensing data, machine tool monitoring, medical prediction ...

Bats as instructive animal models for studying longevity and aging

open access: yesAnnals of the New York Academy of Sciences, Volume 1541, Issue 1, Page 10-23, November 2024.
Every organism's lifespan depends on the balance of protective and regenerative versus degenerative processes. Bats (Chiroptera) live far longer than is predicted by their small body size. Recent studies explore mechanisms underlying their longevity and have raised the question of how their aging compares to that of equally long‐lived primates.

Ultrasonic predator-prey interactions in water– convergent evolution with insects and bats in air?

open access: yesFrontiers in Physiology, 2013
Toothed whales and bats have independently evolved biosonar systems to navigate and locate and catch prey. Such active sensing allows them to operate in darkness, but with the potential cost of warning prey by the emission of intense ultrasonic signals ...

Sperm whale predator-prey interactions involve chasing and buzzing, but no acoustic stunning [PDF]

open access: yes, 2016
Field work in Norway was funded by the Carlsberg Foundation and the National Danish Research Council to PTM. The NMFS study was funded by the U.S. Mineral Management Service.

Numerical Study of the Effect of Furrows on Biosonar Beamforming in Aselliscus Stoliczkanus Bat

open access: yesArchives of Acoustics, 2017
The Aselliscus Stoliczkanus bat, studied here, has intricately shaped structures surrounding the nostrils. These structures are hypothesised to have influence on animals’ acoustic radiation patterns.

Foraging behavior and Doppler shift compensation in echolocating hipposiderid bats, I-Iipposideros bicolor and I-Iipposideros speoris [PDF]

open access: yes, 1984
1. Two hipposiderid bats,H. bicolor andH. speoris, were observed in their natural foraging areas in Madurai (South India). Both species hunt close together near the foliage of trees and bushes but they differ in fine structure of preferred hunting space:

Perceptual modalities guiding bat flight in a native habitat [PDF]

open access: yes, 2018
Flying animals accomplish high-speed navigation through fields of obstacles using a suite of sensory modalities that blend spatial memory with input from vision, tactile sensing, and, in the case of most bats and some other animals, echolocation ...

Wireless recording of the calls of Rousettus aegyptiacus and their reproduction using electrostatic transducers [PDF]

open access: yes, 2008
Bats are capable of imaging their surroundings in great detail using echolocation. To apply similar methods to human engineering systems requires the capability to measure and recreate the signals used, and to understand the processing applied to ...
