System identification and control of an Arleigh Burke Class Destroyer using an extended Kalman filter
(Massachusetts Institute of Technology, 2000)
Response surface methods applied to submarine concept exploration
(Massachusetts Institute of Technology, 2001)
It is estimated that 70 to 85 percent of a naval ship's life-cycle cost is determined during the concept exploration phase which places an importance in the methodology used by the designer to select the concept design. ...
Surface-surface intersection with validated error bounds
(Massachusetts Institute of Technology, 2005)
This thesis presents a robust method for tracing intersection curve segments between continuous rational parametric surfaces, typically rational polynomial parametric surface patches. Using a validated ordinary differential ...
Collision with a crushable bow
(Massachusetts Institute of Technology, 2000)
Computational improvements to predict propeller performance at off design conditions
(Massachusetts Institute of Technology, 2002)
An alternate method for the determination of aircraft carrier limiting displacement for strength
(Massachusetts Institute of Technology, 2001)
Pipe circularity reformation via line heating
(Massachusetts Institute of Technology, 2001)
Fabrication of pipes requires the use of several manufacturing processes, such as bending, welding, drilling and wringing. However, in most cases the circular ends deviate from true circles and need reformation to be welded ...
Verification of a six-degree of freedom simulation model for the REMUS autonomous underwater vehicle
(Massachusetts Institute of Technology, 2001)
mproving the performance of modular, low-cost autonomous underwater vehicles (AUVs) in such applications as long-range oceanographic survey, autonomous docking, and shallow-water mine countermeasures requires improving the ...
Forces and moments due to unsteady motion of an underwater vehicle
(Massachusetts Institute of Technology, 2003)
This research examines the effect of unsteady motion on the forces and moments experienced by an underwater vehicle in shallow water. The test platform is the REMUS Autonomous Underwater Vehicle developed by the Woods Hole ...
An experimental study of the oil evolution in critical piston ring pack regions and the effects of piston and ring designs in an internal combustion engine utilizing two-dimensional laser induced fluorescence and the impact on maritime economics
(Massachusetts Institute of Technology, 2004)
Faced with increasing concern for lubricating, oil consumption and engine friction, it is critical to understand the oil transport mechanisms in the power cylinder system. Lubricating oil travels through distinct regions ...
