Autonomous Vision Navigation of Spacecraft in Lunar Orbit
NASA aims to achieve unprecedented navigational reliability for the first manned lunar mission of the Orion spacecraft in 2023. A technique for accomplishing this is to integrate autonomous feature tracking as an added ...
Minimization of Roll Firings for Optimal Propellant Maneuvers
Attitude control of the International Space Station (ISS) is critical for operations, impacting power, communications, and thermal systems. The station uses gyroscopes and thrusters for attitude control, and reorientations ...
A Resistor Network Model for the Determination of Electrical and Thermal Properties of Nanocomposites
Superior electrical, thermal, and mechanical properties of carbon nanotubes have made them popular candidates for use as fillers in polymer nanocomposites. This thesis presents a numerical model developed to determine the ...
Analysis of Hysteretic Systems: Preisach Formalism and Bouc-Wen Modeling
The inherently nonlinear phenomenon of hysteresis is notoriously difficult to model. Of notable interest are the inverse models of hysteresis which identify the parameters of a particular model to closely match experimental ...
Monte Carlo Simulations on Resistive Switching Memristor Modeling
Promising attributes in data processing such as faster read/write times, longer retention, and superior scalability have put resistive switching memristors in the spotlight of research. This thesis presents a numerical ...
