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 ...
Uniform flow past a rigid sphere by the spectral numerical methods
(Monterey, California. Naval Postgraduate School, 1997-03)
A steady, axially symmetric, incompressible, viscous flow past a rigid sphere is numerically simulated by using a numerical scheme, based on spectral methods. The equations have been reduced to two sets of nonlinear second ...
Experimental studies of joint flexibility for PUMA 560 robot
(1987-03)
This paper investigates flexibility of the PUMA 560 industrial robot arm. The purpose is accomplished by measurement of the flexural stiffness of the key joints in the system. The joint flexibilities are linear in nature ...
An investigation of the feasibility of implementing substantial finite element codes on popular microcomputers.
(Monterey, California. Naval Postgraduate School, 1982)
Sensor development for intelligent processing of age hardenable aluminum alloys
(Monterey, California. Naval Postgraduate School, 1995-03)
The objective of this research is to further develop a sensor system which can be used to continuously monitor the aging response of heat treatable aluminum alloys. This type of system would allow for 'real time' evaluation ...
Testing of a shrouded, short mixing stack gas eductor model using high temperature primary flow.
(Monterey, California. Naval Postgraduate School, 1982-10)
An existing apparatus for testing models of gas eductor systems using high temperature primary flow was redesigned and modified to provide improved control and performance over a wide range of gas temperatures and flow ...
Earthquake resistant submarine drydock block system design
(Monterey California. Naval Postgraduate School, 1988)
This thesis develops a 3-degree of freedom submarine drydock blocking system computer aided design package. Differential equations of motion are developed to take into account high blocking systems, wale shores, and side ...
Optimization of three dimensional combined truss/frame structures
(Monterey, California. Naval Postgraduate School, 1982-10)
A finite element code is developed for analysis and design of three-dimensional truss and frame structures. Structures are designed for minimum weight subject to constraints on: member stresses, Euler buckling, shell ...
Synthesis of a collision tolerant fixed navigation marker system.
(Monterey, California. Naval Postgraduate School, 1982)
A preliminary investigation of the corrosion and stress-corrosion susceptibility of thermomechanically processed high magnesium aluminum magnesium alloys
(Monterey, California. Naval Postgraduate School, 1981-09)
The stress corrosion cracking susceptibility and general corrosion characteristics of four thermomechanically processed high-Magnesium, Aluminum-Magnesium alloys were evaluated and compared to those of 7076-T6.
