Effects of positional information time lags on motion stability of autonomous vehicles.
(Monterey, California. Naval Postgraduate School, 1992-09)
Highly maneuverable ocean going vehicles require quick response, control, and
guidance to maintain accurate track keeping characteristics. Ocean vehicles, however, may
experience significant lags in their inertial ...
Application of numerical optimization techniques to surface combatant design synthesis
(Monterey, California. Naval Postgraduate School, 1998-09)
This thesis presents the effort to incorporate a numerical optimizer into an existing ship design synthesis math model. The goal is to improve the functionality of the model while retaining the intrinsic value of the model's ...
Solution strategies for second order, nonlinear, one dimensional, two point boundary value problems by FEM analysis
(Monterey, California: Naval Postgraduate School, 1990-12)
This research demonstrates the Galerkin FEM's ability to provide approximate solutions of second order, nonlinear, one dimensional, two point boundary value problems. The research concentrates on the development of ...
Thermal cycling behavior of unidirectional and cross-plied P100 Gr/6061 aluminium composites.
(Monterey, California. Naval Postgraduate School, 1992-09)
The thermal strain response of as-cast samples of 40% PI 00 graphite fiber
reinforced 6061 Al composites in the unidirectionally reinforced and the [0/90]
cross-plied configuration was studied. Thermal strain hysteresis ...
Numerical field model simulation of fire and heat transfer in a rectangular compartment
(Monterey, California. Naval Postgraduate School, 1992-09)
Shipboard fires have been the bane of mariners since man's earliest attempts to sail the sea. Understanding the behavior of fire in an enclosed space such as those found on today's modern seagoing vessels will greatly ...
Use of Hopfield networks for system identification and failure detection in autonomous underwater vehicles
(Monterey, California. Naval Postgraduate School, 1991-09)
In the early 1980's John J. Hopfield developed a recurrent network based on a model of biological neurons. In his model, each neurons accepts inputs from all other neurons in the network, modifies each input with a weight ...
Studies of intermetallic growth in Cu-solder systems and wettability at solid-liquid interfaces
(Monterey, California. Naval Postgraduate School, 1991-09)
The metallurgical bond formed between tin-lead solder and the copper substrate is characterized by the formation of an intermetallic compound layer. The growth of the intermetallic layer is the result of competing mechanisms, ...
Six degree-of-freedom motions in short crested seas
(Monterey, California. Naval Postgraduate School, 2002-09)
The scope of this thesis is to investigate the vertical and horizontal plane motions of surface ships in close proximity towing in irregular waves. Strip theory calculations have been utilized in order to predict the ...
Evaluation and analysis of DDG-81 simulated athwartship shock response
(Monterey, California. Naval Postgraduate School, 2004-06)
In 2001 the USS WINSTON CHURCHILL (DDG-81) was subjected to three underwater explosions as part of a ship shock trial. Using the actual trial data from experiment and three-dimensional dynamic models of the ship and ...
Motion analysis of a trolly interface for ship-to-ship cargo transfer
(Monterey, Calif. Naval Postgraduate School, 2002-12)
The goal of this thesis is to investigate the effectiveness of a trolley interface for ship-to-ship cargo transfer. The new interface alleviates some of the torsional problems associated with existing ramp designs and can ...
