The Rise of Regional Hegemons: Assessing Implications for the International System through a Neo-realist Perspective
… nations are able to influence the international system. To see how much of an effect these rapidly developing nations are having within the international system, they will be measured against 5 indicators that correlate with becoming a rising regional hegemon, a feature of a multi-polar system. …

The Effects of Strain and Vacancies on the Electric and Vibrational Properties of Ferroelectric BaTiO3 from First-principles
… in this dissertation to enable the study of polarization for charged system.</p> <p>In this work I report behaviors of polarization in rhombohedral (R3m) BaTiO3 (BTO) that do not conform with intuition, or the current state of known behavior of epitaxially strained BTO. These studies reveal a …

Competing polar and nonpolar distortions and phase transitions in low-dimensional materials
… phases and phase transitions in low-dimensional systems is essential for the understanding and control of nanoscale devices. Theoretical models aided by first-principles calculations have proven invaluable in this respect. However, observed behaviour often differs from what is predicted …

Transit network design for areas with low and/or heterogeneous demand
… in transit service, which often leads to higher system costs and undesirable passenger experience (e.g., transfers) as well. This dissertation proposes a series of transit network design methods that can be used to improve transit service under these circumstances. It first presents an …

Flight Testing Small UAVs for Aerodynamic Parameter Estimation
<p>A flight data acquisition system was developed to aid unmanned vehicle designers in verifying the vehicle's design performance. The system is reconfigurable and allows the designer to choose the correct combination of complexity, risk, and cost for a given flight test. The designer can also …
