Optimization of an Unfurlable Space Structure
Deployable structures serve a large number of space missions. They are vital since spacecraft are launched by placing them inside launch vehicle payload fairings of limited volume. Traditional spacecraft design often involves large components. These components could have power, communication, or …

Phase Space Structure of Disequilibrium in the Milky Way
… Gaia Data Release 2, observations of spiral structure in the vertical phase space of the Milky Way have been made. In this thesis we set out to explain these structures, using a combination of analytic modeling, simulations, and Dynamic Mode Decomposition to study explicitly their formation …

Optimization of Geometric Parameters for a Deployable Space Structure
Deployable structures are used for many different spacecraft applications like solar arrays, antennas, and booms. They allow spacecraft with large structural components to comply with the volume restrictions of launch platforms. This research optimizes the shape and size of these structural …

An infinite loop space structure for K-theory of bimonoidal categories
… that it is equivalent to the algebraic K-theory space of the ring spectrum KR. In this thesis we show that K(R) is the group completion of the classifying space of the 2-category ModR of modules over R, and show that ModR is a symmetric monoidal 2-category. We explain how to use this symmetric …

Optimization of Geometric Parameters and Material Properties for a Deployable Space Structure
Traveling to space requires a great deal of energy. This then limits the size of spacecraft accessible to transport to space. An optimization of a flexible tube that could be used as a satellite deployable structure was conducted by varying the cross section of the tube and its composite material …

The response of a single wall space structure to impact by cometary meteoroids of various shapes
Linear, small deflection plate theory is used to study the stress at the contact axis and the deflection of an infinite plate caused by the impact of an axisymmetric cometary meteoroid. The analysis assumes that momentum exchange is the primary mechanism, that the time of exchange is instantaneous, …

Finding and exploiting structure in complex systems via geometric and statistical methods
… system can be understood by analyzing the phase space structure of that system. We apply geometric and statistical techniques to two Hamiltonian systems to find and exploit structure in the phase space that helps us get qualitative and quantitative results about the phase space transport. While …

Dynamics and control of a spatial truss actuator
The use of active control actuators integral to a structure's construction has been suggested in large space structure technology. A 3-D active truss is presented and analyzed and control of the actuators to reduce the vibration of a flexible rod attached to the structure is discussed. A state …
