Foliage Echoes and Sensing in Natural Environments
(Virginia Tech, 2017-09-07)
Foliage is very common feature in the habitats of echolocation bats and thus its echoes constitute the major input of bats' sensory systems. Acquiring useful information from vegetation echoes facilitates the bats significantly ...
Analysis of Bat Biosonar Beampatterns: Biodiversity and Dynamics
(Virginia Tech, 2017-01-24)
Across species, bats exhibit wildly disparate differences in their noseleaf and pinnae shapes. Within Rhinolophid and Hipposiderid families, bats actively deform their pinnae and noseleaf during biosonar operation. Both ...
Toward Efficient Bio-Inspired Propulsion: The Effect of Propulsor Shape and Kinematics on System Performance and Efficiency during Bio-inspired Locomotion
(Virginia Tech, 2017-08-25)
Both bird and fish locomotion are thought to be more efficient than the equivalent man-made vehicles driven by propellers/impellers and jet engines. Through studies that decompose the different kinematic and shape effects ...
Numerical analysis of bat noseleaf dynamics and its impact on the encoding of sensory information
(Virginia Tech, 2017-02-06)
Horseshoe bats possess a sophisticated biosonar system that helps them to negotiate complex unstructured environments by relying primarily on the sound as the far sense. For this, the bats emit brief ultrasonic pulses and ...
