A Low-Cost Acoustic Emission Sensor Based on Piezoelectric Diaphragm
(2020-08-15)
Sensor monitoring is widely used in modern industrial automation. Industries require efficient and cost-effective monitoring and control systems. Regarding monitoring, new low-cost piezoelectric sensors have been tested ...
The Caatinga Orchestra: Acoustic indices track temporal changes in a seasonally dry tropical forest
(2021-10-01)
Advances in technologies for data acquisition, storage and analysis have boosted Acoustic Ecology studies, but protocols are still lacking. There is a need of more research to understand which methodologies can be applied ...
Calling sites and acoustic partitioning in species of the Hyla nana and rubicundula groups (Anura, Hylidae)
(2006-07-01)
We analysed spatial and acoustic partitioning among four species of Hyla belonging to two species-groups: nana (H. nana and H. sanborni) and rubicundula (H. elianeae and H. jimi). Field activities were conducted at three ...
Visual and acoustic communication in the Brazilian torrent frog, Hylodes asper (Anura : Leptodactylidae)
(Herpetologists League, 1999-09-01)
We studied the signaling, territorial, and courtship behaviors of the diurnal frog Hylodes asper. Visual and acoustic communication were used during intraspecific interactions involving males, females. and subadults. Hylodes ...
A Comparative Analysis Applied to the Partial Discharges Identification in Dry-Type Transformers by Hall and Acoustic Emission Sensors
(2022-03-01)
Dry-type insulated transformers stand out for their higher applicability in substations, high-voltage instrumentation systems, and electrical installations. In this machine, the insulation system is constituted of dielectric ...
