An investigation of exploitation versus exploration in GBEA optimization of PORS 15 and 16 Problems

Description: It was hypothesized that the variations in time to solution are driven by the competing mechanisms of exploration and exploitation.This thesis explores this hypothesis by examining two contrasting problems that embody the hypothesized tradeoff between exploration and exploitation. Plus one recall store (PORS) is an optimization problem based on the idea of a simple calculator with four buttons: plus, one, store, and recall. Integer addition and store are classified as operations, and one and me… more

Rhodium Catalysts in the Oxidation of CO by O<sub>2</sub> and NO: Shape, Composition, and Hot Electron Generation

Description: It is well known that the activity, selectivity, and deactivation behavior of heterogeneous catalysts are strongly affected by a wide variety of parameters, including but not limited to nanoparticle size, shape, composition, support, pretreatment conditions, oxidation state, and electronic state. Enormous effort has been expended in an attempt to understand the role of these factors on catalytic behavior, but much still remains to be discovered. In this work, we have focused on deepening the pr… more

Laser Intertial Fusion Energy: Neutronic Design Aspects of a Hybrid Fusion-Fission Nuclear Energy System

Description: This study investigates the neutronics design aspects of a hybrid fusion-fission energy system called the Laser Fusion-Fission Hybrid (LFFH). A LFFH combines current Laser Inertial Confinement fusion technology with that of advanced fission reactor technology to produce a system that eliminates many of the negative aspects of pure fusion or pure fission systems. When examining the LFFH energy mission, a significant portion of the United States and world energy production could be supplied by LF… more

Lessons from the Past: Possible Courses of Action for the Conflict in Syria

Description: Undergraduate thesis examining the Syrian conflict and the international community's struggle to find an appropriate response. This thesis reviews the conflicts that occurred in Bosnia and Rwanda, the interventions that took place within these states, and how a resolution to these conflicts was created. From this information, the author determines what conflict management strategies had the most success and what types of outside interventions were failures and the similarities of these instance… more

Wither the Whip, Strengthen the Sword: Colonial Legacy and Geno-/Politicide in the Post-Colonial World, 1945-2012

Description: Undergraduate thesis examining the causes of geno-/politicides and the potential correlation between colonial legacy and the increased likelihood of seeing geno-/politicide across all newly independent states post-WWII from 1945-2012. This study reviews colonialism through an anthropological and sociological lens and applies it to state-structure's impact on political violence.
