Optimal fault detection and resolution during maneuvering for Autonomous Underwater Vehicles
(Monterey, California. Naval Postgraduate School, 2000-03)
In order to increase robustness, reliability, and mission success rate, autonomous vehicles must detect debilitating system control faults. Prior model-based observer design for 21UUV was analyzed using actual vehicle ...
Propagation of fire generated smoke in shipboard spaces with heat source
(Monterey, California. Naval Postgraduate School, 2000-09)
The propagation of fire generated smoke and heat transfer into a shipboard space has been computationally modeled using a commercial code generated by Computational Fluid Dynamics Research Corporation (CFDRC). The space ...
Modeling of thermal and mechanical effects during friction stir processing of nickel-aluminum bronze
(Monterey, California. Naval Postgraduate School, 2004-09)
Friction Stir Processing (FSP), although relatively simple in concept, results in an extremely complex thermomechanical treatment to the material being processed. Previous studies of FSP have shown that the process results ...
Molecular dynamics simulation of fatigue damage in metals
(Monterey, California. Naval Postgraduate School, 2003-12)
Molecular dynamics simulation was conducted to better understand the mechanism of fatigue failure and to identify a parameter(s) that can indicated progressive damage due to cyclic loading. The Embedded Atom Method (EAM) ...
Experiments with the REMUS AUV
(Monterey California. Naval Postgraduate School, 2004-06)
This thesis centers around actual field operations and post-mission analysis of data acquired using a REMUS AUV operated by the Naval Postgraduate School Center for Autonomous Underwater Vehicle Research. It was one of ...
Investigation and development of oil-injection nozzles for high-cycle fatigue rotor spin test
(Monterey, California. Naval Postgraduate School, 2005-03)
Resonant excitation tests of rotor blades in vacuum spin pits using discrete oil jets showed that impact erosion of the blades could limit test times, but lower excitation amplitudes were produced using mist nozzles. ...
Tracking control of autonomous underwater vehicles
(Monterey, Calif. Naval Postgraduate School, 2002-12)
Recovery of Autonomous Underwater Vehicles (AUVs) can often be an autonomous operation itself. In the case of an AUV that is launched and recovered at some significant depth below the surface, the recovery platform to which ...
Microstructure characterization of friction-stir processed nickel-aluminum bronze through orientation imaging microscopy
(Monterey, California. Naval Postgraduate School, 2002-09)
The effect of friction-stir processing (FSP) on the microstructure of a cast nickel-aluminum bronze (NAB) material has been characterized by various micro-analytical methods including orientation imaging microscopy (OIM). ...
Multi-scale analysis of a 2/2-twill woven fabric composite
(Monterey, California. Naval Postgraduate School, 2002-03)
A micro-mechanical unit-cell model was developed for 2/2-twill woven fabric composites. A multi-scale bi-directional micro/macro-mechanical analysis technique was applied to the model in an effort to estimate effective ...
Military-media relationships : identifying and mitigating military-media biases to improve future military operations
(Monterey, California. Naval Postgraduate School, 2003-06)
A noticeable civil-military gap has emerged in American society where the public does not fully understand the mission of the military, and the military does not understand the expectations and demands by the public in a ...
