Zhang, Zhishuai (2012-10-19)Characterization of connectivity in compartmentalized deepwater Gulf of Mexico (GoM) reservoirs is an outstanding challenge of the industry that can significantly impact the development planning and recovery from these ...
-
Georgieva-Hristova, Yulia Nekova (2011-10-21)The results presented in this dissertation concern two different types of tomographic imaging. The first part of the dissertation is devoted to the time reversal method for approximate reconstruction of images in ...
-
Boada, Steven Alvaro (2016-08-02)The distribution of massive clusters of galaxies depends strongly on the total cosmic mass density, the mass variance, and the dark energy equation of state. As such, measures of galaxy clusters can provide constraints on ...

Mesh independent convergence of modified inexact Newton methods for second order nonlinear problems Kim, Taejong (Texas A&M University, 2006-08-16)In this dissertation, we consider modified inexact Newton methods applied to second order nonlinear problems. In the implementation of Newton's method applied to problems with a large number of degrees of freedom, it is ...
-
Joshi, Sunnie (2012-10-19)This dissertation focuses on a novel approach for characterizing the mechanical behavior of an elastic body. In particular, we develop a mathematical tool for the estimation of residual stress field in an elastic body that ...
-
Allmaras, Moritz (2012-02-14)In this dissertation, two recent problems from tomographic imaging are studied, and results from numerical simulations with synthetic data are presented. The first part deals with ultrasound modulated optical tomography, ...
-
Sahu, Amit K. (2009-05-15)The statistical evaluation of molecular imaging approaches for detecting, diagnosing, and monitoring molecular response to treatment are required prior to their adoption. The assessment of fluorescence-enhanced optical ...
-
Muddamallappa, Mallikarjunaiah S (2015-12-12)The work presented in this dissertation focuses on extending a recent effort of developing brittle fracture theory with an aim of achieving bounded crack-tip stress and strain without the use of extra near-tip cohesive ...
-
Taware, Satyajit Vijay (2012-10-19)Reservoir management, sometimes referred to as asset management in the context of petroleum reservoirs, has become recognized as an important facet of petroleum reservoir development and production operations. In the ...
-
Alhuthali, Ahmed Humaid H. (2010-01-16)Waterflood optimization via rate control is receiving increased interest because of rapid developments in the smart well completions and I-field technology. The use of inflow control valves (ICV) allows us to optimize the ...
-
Wang, Kainan (2014-04-18)The Bayesian method has proven to be a powerful way of modeling inverse problems. The solution to Bayesian inverse problems is the posterior distribution of estimated parameters which can provide not only estimates for the ...
-
Alrashed, Fahad Saleh (2015-05-04)We study and implement methods to solve the variable density Navier-Stokes equations. More specifically, we study the transport equation with the level set method and the momentum equation using two methods: the projection ...
-
Sharma, Mohan (2012-10-19)With the depletion of the existing reservoirs and the decline in oil discoveries during the last few decades, enhanced oil recovery (EOR) methods have gained a lot of attention. Among the various improved recovery methods, ...
-
Wang, Fang (2014-06-26)An inverse problem reconstructs the unknown internal parameters of a subject based on collected data derived synthetically or from real measurements. Inverse problems often lack the well-posedness defined by J. Hadamard; ...
-
Ghesmati, Arezou (2018-01-18)We propose and implement an automatic hp-adaptive refinement algorithm for the Stokes model problem. In this work, the strategy is based on the earlier work done by Dörfler at al. in 2007 for the Poisson problem. Similar ...
-
Thompson, Travis Brandon (2013-07-19)The incompressible Navier-Stokes equations have proven formidable for nearly a century. The present difficulties are mathematical and computational in nature; the computational requirements, in particular, are exponentially ...
-
Castanon Quiroz, Daniel (2016-04-15)The research presented in this dissertation focus on the numerical approximation of the magnetohydrodynamic (MHD) equations in the von K´arm´an Sodium (VKS) set-up. These studies are performed with the SFEMaNS MHD code ...
