Technology Transfer to Underwater Archaeology: The LAHKE Project at the Submerged Neolithic Site of La Marmotta

Archaeological Prospection, EarlyView.
ABSTRACT This document is a report on the field application of non‐invasive geophysical and robotic prospecting methods at the submerged Neolithic site of La Marmotta (Lake Bracciano, Italy), within the LAHKE (LAke Heritage Knowledge and Exploration) project; the study focuses on the practical validation, adaptation and transfer of existing ...

Experimental Verification of a Depth Controller using Model Predictive Control with Constraints onboard a Thruster Actuated AUV [PDF]

, 2012
In this work a depth and pitch controller for an autonomous underwater vehicle (AUV) is developed. This controller uses the model predictive control method to manoeuvre the vehicle whilst operating within the defined constraints of the AUV actuators ...

Screening Interactive Impact of Dietary Bivalent Metallic Ions on S. anguivi Bioactive Components: Bitterness Attenuation and Antioxidant Activities Augmentation

Food Chemistry International, EarlyView.
Unpleasant bitterness associated with bioactive components of S. anguivi, a vegetal fruit with many therapeutics functionalities, was attenuated on interaction with dietary bivalent metallic ions with concomitant augmentation of antioxidant activity. ABSTRACT Bioactive components of S.

A novel approach for in situ benthic habitat characterization

Limnology and Oceanography: Methods, EarlyView.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Towards Arctic AUV Navigation [PDF]

IFAC-PapersOnLine, 2018
Abstract The navigational drift for Autonomous Underwater Vehicles (AUVs) operating in open ocean can be bounded by regular surfacing. However, this is not an option when operating under ice. To operate effectively under ice requires an on-board navigation solution that does not rely on external infrastructure.

Eliciting expert judgement for the probability of AUV loss in contrasting operational environments [PDF]

, 2007
Each time an autonomous underwater vehicle (AUV) is used in the sea there is a non-zero probability of loss. Quantifying probability of loss is not an exact science; therefore much depends on the fault history of the vehicle, the operational environment ...

Underwater Target Tracking Using Forward-Looking Sonar for Autonomous Underwater Vehicles

Sensors, 2019
In the scenario where autonomous underwater vehicles (AUVs) carry out tasks, it is necessary to reliably estimate underwater-moving-target positioning.

Enabling Under Ice Glider Operations: A Backseat Driver Approach

Journal of Field Robotics, EarlyView.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Virtual Elastic Tether: A New Approach for Multi‐Agent Navigation in Confined Aquatic Environments

Journal of Field Robotics, EarlyView.
ABSTRACT Underwater navigation is a challenging area in the field of mobile robotics due to inherent constraints in self‐localization and communication in underwater environments. Some of these challenges can be mitigated by using collaborative multi‐agent teams.
