Design and experiment of a Long Range Autonomous Underwater Vehicle for Ocean Acoustic Data Observation

Polish Maritime Research
In order to realise noise measurement and target detection, this paper designs a long range autonomous underwater vehicle (LRAUV), namely ‘Petrel’, which contains a variable buoyancy system, attitude adjustment mechanisms, pitch and heading control ...

Wake-Responsive AUV Guidance Assisted by Passive Sonar Measurements

Journal of Marine Science and Engineering
To make an Autonomous Underwater Vehicle (AUV) chase a moving target ship that generates wake, wake-responsive guidance can be used. This scenario is applicable to making an underwater torpedo pursue a moving target ship until hitting the target.

Multi-AUV Cooperative Target Hunting Based on Improved Potential Field in a Surface-Water Environment

Applied Sciences, 2018
In this paper, target hunting aims to detect target and surround the detected target in a surface-water using Multiple Autonomous Underwater Vehicles (multi-AUV) in a given area. The main challenge in multi-AUV target hunting is the design of AUV’s

The Constraints of Conformal Symmetry on RG Flows

, 2011
If the coupling constants in QFT are promoted to functions of space-time, the dependence of the path integral on these couplings is highly constrained by conformal symmetry.

The Baryonic Branch of Klebanov-Strassler Solution: a Supersymmetric Family of SU(3) Structure Backgrounds

, 2004
We exhibit a one-parameter family of regular supersymmetric solutions of type IIB theory that interpolates between Klebanov-Strassler (KS) and Maldacena-Nunez (MN).

First AUV and ROV investigation of seismogenic faults in the Alboran Sea (Western Meditarranean) [PDF]

, 2016
In May-June 2015 we carried out the SHAKE cruise on board the RV “Sarmiento de Gamboa” the first in situ investigation using state-of-the-art underwater vehicles, the AUVs “AsterX” and “IdefX” (IFREMER, France) and the ROV “Max Rover” (HCMR, Greece ...

On \epsilon-conjecture in a-theorem

, 2011
The derivation of the a-theorem recently proposed by Komargodski and Schwimmer relies on the \epsilon-conjecture that demands decoupling of dilaton from the rest of the infrared theory.

Omnidirectional underwater surveying and telepresence [PDF]

, 2016
Exploratory dives are traditionally the first step for marine scientists to acquire information on a previously unknown area of scientific interest. Manned submersibles have been the platform of choice for such exploration, as they allow a high level ...
