Visually Mapping the RMS Titanic: Conservative Covariance Estimates for SLAM Information Filters
(SAGE, 2006-12)
This paper describes a vision-based, large-area, simultaneous localization and mapping (SLAM) algorithm that respects the low-overlap imagery constraints typical of underwater vehicles while exploiting the inertial sensor ...
Toward a Platform-Independent Acoustic Communications and Navigation System for Underwater Vehicles
(IEEE, 2009-10-26)
This paper presents a platform-independent
acoustic communication (Acomms) system that enables multiple
nodes (any combination of underwater vehicles, surface
ships, and fixed beacons) to simultaneously exchange data
and ...

Singularity image method for electrical impedance tomography of bubbly flows
(IOP Publishing Ltd, 2003-08-01)
A singularity image method is applied to the electrical impedance tomography of gas–liquid flows in a two-dimensional circular domain. Algorithms that use analytic complex functions, dipoles and the Milne-Thomson circle ...
High Reynolds number experimentation in the US Navy's William B Morgan Large Cavitation Channel
(IOP Publishing Ltd, 2005-09-01)
The William B Morgan Large Cavitation Channel (LCC) is a large variable-pressure closed-loop water tunnel that has been operated by the US Navy in Memphis, TN, USA, since 1991. This facility is well designed for a wide ...
Pose-graph Visual SLAM with Geometric Model Selection for Autonomous Underwater Ship Hull Inspection
(IEEE, 2009-10-10)
This paper reports the application of vision based
simultaneous localization and mapping (SLAM) to the problem
of autonomous ship hull inspection by an underwater
vehicle. The goal of this work is to automatically map ...
Seaborne Petrochemical Spill Analysis Within the United States, 1992–1999
(Springer-Verlag; Springer-Verlag New York Inc., 2003-04)
An Overview of Autonomous Underwater Vehicle Research and Testbed at PeRL
(Marine Technology Society, 2009)
This article provides a general overview of the autonomous underwater vehicle (AUV) research thrusts being pursued within the Perceptual Robotics Laboratory (PeRL) at the University of Michigan. Founded in 2007, PeRL’s ...
Differential Equations of Stiffened Panels
(University of Michigan, 2001-03-01)
This text presents the theory used to implement in the LBR5 software an analytical solution of the stiffened panels governing equations. For that purpose, Fourier series expansions are used to solve the governing differential ...
