Dynamic Trust Management for Mobile Networks and Its Applications
(Virginia Tech, 2013-06-05)
Trust management in mobile networks is challenging due to dynamically changing network environments and the lack of a centralized trusted authority. In this dissertation research, we design and validate a class of dynamic ...
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)
Oral Drug Delivery -- Molecular Design and Transport Modeling
(Virginia Tech, 2013-12-30)
One of the major challenges faced by the pharmaceutical industry is to accelerate the product innovation process and reduce the time-to-market for new drug developments. This involves billions of dollars of investment due ...
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. ...
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. ...
