AUV experiments in obstacle avoidance
Proceedings of OCEANS 2005 MTS/IEEE, 2005 Reactive obstacle avoidance (OA) is an important step in attaining greater autonomy in autonomous underwater vehicles (AUV). For AUVs that conduct underwater surveys, avoidance of uncharted obstacles can improve vehicle survivability. This paper discusses initial experiments at the Center for AUV Research in obstacle detection and avoidance using the ...

Real‐Time Detection and Prevention of DoS Attack in Unmanned Marine Vehicles Using Machine Learning
SECURITY AND PRIVACY, Volume 9, Issue 2, March/April 2026.ABSTRACT Unmanned marine vehicles (UMVs) are one of the most crucial components of the underwater communication and surveillance system in the marine and oceanographic environment. This research introduces a novel approach to stabilize the connection in an unstable underwater environment by inheriting features of communication velocities.

Added Resistance of an AUV Moving Inside a Water Pipeline Due to Wall Proximity
International Journal of Maritime Technology, 2015 This paper evaluates the added resistance of a torpedo shape AUV, moving inside a water pipeline, due to wall effects within the tube. Today, there are long length pipelines of water or petroleum that need to regular inspection.

New constraints on dust emission and UV attenuation of z=6.5-7.5 galaxies from millimeter observations [PDF]
, 2014 We have targeted two recently discovered Lyman break galaxies (LBGs) to search for dust continuum and [CII] 158 micron line emission. The strongly lensed z~6.8 LBG A1703-zD1 behind the galaxy cluster Abell 1703, and the spectroscopically confirmed z=7 ...

TESOL Journal, Volume 17, Issue 1, March 2026.ABSTRACT The vocabulary load of university lectures and the coverage of academic vocabulary in spoken discourse have been used as benchmarks in researching whether various listening sources lexically correspond to actual university lectures. However, it remains unexplored whether contrived lecture passages from international academic English ...

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.Abstract In oceanic frontal regions, isopycnal stirring induces lateral thermohaline intrusion. Previous studies have observed interleaving layers in the Izu Ridge and Kuroshio Extension attributed to isopycnal stirring driven by mesoscale eddies and submesoscale flows.
