Acoustic classification of buried objects with mobile sonar platforms
(Massachusetts Institute of Technology, 2006)
In this thesis, the use of highly mobile sonar platforms is investigated for the purpose of acoustically classifying compact objects on or below the seabed. The extension of existing strategies, including synthetic aperture ...
Uncertainty analysis in a shipboard integrated power system using multi-element polynomial chaos
(Massachusetts Institute of Technology, 2007)
The integrated power system has become increasingly important in electric ships due to the integrated capability of high-power equipment, for example, electromagnetic rail guns, advance radar system, etc. Several parameters ...
Computations of fully nonlinear three-dimensional wave-body interactions
(Massachusetts Institute of Technology, 2010)
Nonlinear effects in hydrodynamics of wave-body interaction problems become critically important when large-amplitude body motions and/or extreme surface waves are involved. Accurate prediction and understanding of these ...
Higher order asymptotic inference in remote sensing of oceanic and planetary environments
(Massachusetts Institute of Technology, 2010)
An inference method based on higher order asymptotic expansions of the bias and covariance of the Maximum Likelihood Estimate (MLE) is used to investigate the accuracy of parameter estimates obtained from remote sensing ...
Integrating seakeeping in the design of semi-displacement and displacement monohulls
(Massachusetts Institute of Technology, 2010)
Early stage ship design and assessment continues to be a challenge for naval architects and ocean engineers. The complex and multifaceted interactions between the different components of the ship and the broad spectrum of ...
Numerical investigation of the flow-body interaction of thin flexible foils and ambient flow
(Massachusetts Institute of Technology, 2006)
Flow-induced flapping of flexible thin bodies is oft observed in our day-to-day lives in phenomena such as flag flapping, and is important in a host of engineering applications. Despite its prevalence, however, this ...
