Slocum Gliders Provide Accurate Near Real-Time Estimates of Baleen Whale Presence From Human-Reviewed Passive Acoustic Detection Information [PDF]

Frontiers in Marine Science, 2020
Mitigating the effects of human activities on marine mammals often depends on monitoring animal occurrence over long time scales, large spatial scales, and in real time. Passive acoustics, particularly from autonomous vehicles, is a promising approach to

The relativistic glider [PDF]

Physical Review D, 2006
We present a purely relativistic effect according to which asymmetric oscillations of a quasi-rigid body slow down or accelerate its fall in a gravitational background.Comment: 3 pages, 2 figures. To appear in Phys Rev

Comparison of Debris Extrusion and Preparation Time by Traverse, R-Motion Glider C, and Other Glide Path Systems in Severely Curved Canals [PDF]

International Journal of Dentistry
This study evaluated debris extrusion by Traverse and R-Motion Glider C during glide path preparation. Seventy-five mesial roots of mandibular molars with severely curved mesiobuccal canals were distributed into five groups: Traverse, R-Motion Glider C ...

Gliders for passive acoustic monitoring of the oceanic environment

Frontiers in Remote Sensing, 2023
Ocean gliders are quiet, buoyancy-driven, long-endurance, profiling autonomous platforms. Gliders therefore possess unique advantages as platforms for Passive Acoustic Monitoring (PAM) of the marine environment.

Development of Recovery System for Underwater Glider

Journal of Marine Science and Engineering, 2022
This study proposes a novel autonomous system that is able to retrieve an underwater glider safely and quickly. After a long-period mission, the glider is out of its energy, floats up in the middle of the sea, and needs retrieval.

Study on the Glider Soaring Strategy in Random Location Thermal Updraft via Reinforcement Learning

Aerospace, 2023
Soaring birds can use thermal updrafts in natural environments to fly for long periods or distances. The flight strategy of soaring birds can be implemented to gliders to increase their flight time.
