Multi-Objective Optimization of Pumping Rates and Well Placement in Coastal Aquifers
(Georgia Institute of Technology, 2003-03)
Saltwater intrusion, which is commonly associated with extensive groundwater extraction, is an important problem for coastal regions. To avoid saltwater intrusion and maintain the integrity of coastal aquifers, proper ...
Hooked on Optimization
(Georgia Institute of Technology, 2010-09-16)
Integer programming is addictive. I got hooked more than forty years ago and I'm still an addict. There are many fun challenges and no indication that the rate of progress has diminished. In this talk I'll tell a little ...
Models and algorithms for dynamic real-time freight train re-routing
(Georgia Institute of Technology, 2018-11-09)
This dissertation focuses on solving a train re-routing problem in a near real-time context for a freight train carrier operating over a large network. A holistic evaluation framework is developed using a time-space network ...
Choice-based revenue management with applications in transportation
(Georgia Institute of Technology, 2020-07-20)
This dissertation consists of three studies on choice-based revenue management. All these studies are motivated by applications that arise in real-world business settings and have not been well addressed in the literature. ...
Sparse seismic signal processing using adaptive dictionaries
(Georgia Institute of Technology, 2016-08-09)
Seismic surveys have become the primary measurement tool of exploration geophysics, both onshore and offshore, with significant signal processing needed to estimate the properties of earth subsurface via seismic wave ...
Cyber-physical acquisition strategy for COTS-based agility-driven engineering
(Georgia Institute of Technology, 2016-04-12)
The rising cost of military aircraft has driven the DoD to increase the utilization of commercial off-the-shelf (COTS) components in new acquisitions. Despite several demonstrated advantages of COTS-based systems, challenges ...
Fragility of California bridges - development of modification factors
(Georgia Institute of Technology, 2017-04-12)
This research study concentrates on the effects of geometric irregularities on the seismic response and fragility analysis of bridges. The experiences of past earthquakes have affirmed that bridges with geometric irregularities ...
A robust methodology for strategically designing environments subject to unpredictable and evolving conditions
(Georgia Institute of Technology, 2019-01-15)
The layout design process, a lean technique, has the potential to provide a manufacturer with significant cost reductions. The major challenge for layout designers is then ensuring this reduction can be maximized, but more ...
Investigations in time-dependent combinatorial optimization problems and their applications
(Georgia Institute of Technology, 2020-05-19)
We explore three distinct but related combinatorial optimization problems involving time. Chapter 2 focuses on a time-indexed integer programming (IP) formulation for solving the Traveling Salesman Problem with Time Windows ...
Multiscale uncertainty quantification for physics-based data-driven materials design and optimization
(Georgia Institute of Technology, 2018-11-09)
Uncertainty is a critical element in computational materials science. From the experimental perspective, the sources of uncertainty include measurement errors caused by instrument, operator, and sensing models, as well as ...
