Research on the decentralized supervisory control of autonomous underwater vehicle [PDF]

, 2004
In order to independently complete some situation-adapted missions in unknown undersea environment, higher-level decision techniques are needed to provide an autonomous underwater vehicle (AUV) with the ability of active autonomy. This paper uses certain

Adaptive Neural Network-Based Prescribed Performance Control of AUVs with Input Saturation

水下无人系统学报
In view of system uncertainty and input saturation of autonomous undersea vehicles(AUVs), an improved adaptive neural network-based prescribed performance control strategy was proposed to track the desired trajectory.

Acute cardiovascular changes following heat exposure during simulated shipboard firefighting

Experimental Physiology, EarlyView.
Abstract Like structural firefighting, shipboard firefighting requires extreme exertion. However, shipboard firefighting may be a unique cardiovascular stress as most sailors lack extensive firefighting experience and may complete significant work before reaching the fire scene.

Glacial Ice‐Front Calving: Internal Wave Generation and Melting

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Small, frequent calving events dominate the behavior of most Arctic marine‐terminating glaciers, yet their oceanographic impacts remain largely unquantified. We present the first direct observations of internal waves generated by modest ice‐fall calving at Kronebreen, Svalbard. High‐resolution current meter and microstructure measurements show

DeepSTARia: enabling autonomous, targeted observations of ocean life in the deep sea

Frontiers in Marine Science
The ocean remains one of the least explored places on our planet, containing myriad life that are either unknown to science or poorly understood. Given the technological challenges and limited resources available for exploring this vast space, more ...

Geographic Variation in Diving Behaviour and Skin Isotope Ratios of Northern Bottlenose Whales, Hyperoodon ampullatus

Ecology and Evolution, Volume 16, Issue 6, June 2026.
High‐resolution multi‐sensor tag data from northern bottlenose whale populations in the northeast and northwest Atlantic showed differences in resting and foraging time budgets and behaviour. Skin biopsy stable isotopes corroborated likely dietary differences. Variability between populations has far‐reaching relevance for ecology and conservation, with

Maneuvering of an over-actuated autonomous underwater vehicle using both through-body tunnel thrusters and control surfaces [PDF]

, 2011
The maneuvering performance of an over-actuated AUV (2m long, 254mm diameter) has been tested operating on the free surface (97% displacement submerged). Straight line speed tests and turning circle tests have been performed.
