MIMO Wireless Networks: Modeling and Optimization
(Virginia Tech, 2010-02-04)
A critical factor affecting the future prospects of wireless networks for wide-scale deployment is network capacity: the end users wish to have their communication experience over wireless networks to be comparable or ...
Optimal Evacuation Plans for Network Flows over Time Considering Congestion
(Virginia Tech, 2011-06-09)
This dissertation seeks to advance the modeling of network flows over time for the purposes of improving evacuation planning. The devastation created by Hurricanes Katrina and Rita along the Gulf Coast of the United States ...
Techniques for mathematical analysis and optimization of agent-based models
(Virginia Tech, 2014-01-23)
Agent-based models are computer simulations in which entities (agents) interact with each other and their environment according to local update rules. Local interactions give rise to global dynamics. These models can be ...
Optimizing analysis pipelines for improved variant discovery
(Virginia Tech, 2014-04-17)
Optimization-Based Guidance for Satellite Relative Motion
(Virginia Tech, 2016-04-07)
Spacecraft relative motion modeling and control promises to enable or augment a wide range of missions for scientific research, military applications, and space situational awareness. This dissertation focuses on the ...
Energy-efficient Wastewater Treatment by Microbial Fuel Cells: Scaling Up and Optimization
(Virginia Tech, 2015-11-06)
Microbial fuel cells (MFCs) are potentially advantageous as an energy-efficient approach to wastewater treatment. For single-chamber tubular MFCs, anode effluent is used as catholyte instead of tap water or buffer solutions. ...
Modeling and Analysis for Optimization of Unsteady Aeroelastic Systems
(Virginia Tech, 2011-11-03)
Simulating the complex physics and dynamics associated with unsteady aeroelastic systems is often attempted with high-fidelity numerical models. While these high-fidelity approaches are powerful in terms of capturing the ...
Planning for Army Force Generation Using Lot Streaming, and Extensions
(Virginia Tech, 2011-11-04)
As the Army transitions to the Army Force Generation (ARFORGEN) deployment cycle, it must adjust its many operations in support of ARFORGEN. Specifically, the Initial Military Training (IMT) must be able to adjust the ...
Optimal Parameters for Doubly Curved Sandwich Shells, Composite Laminates, and Atmospheric Plasma Spray Process
(Virginia Tech, 2018-01-31)
Optimization is a decision making process to solve problems in a number of fields including engineering mechanics. Bio-inspired optimization algorithms, including genetic algorithm (GA), have been studied for many years. ...
Randomization for Efficient Nonlinear Parametric Inversion
(Virginia Tech, 2018-06-04)
Nonlinear parametric inverse problems appear in many applications in science and engineering. We focus on diffuse optical tomography (DOT) in medical imaging. DOT aims to recover an unknown image of interest, such as the ...
