Jiang, Jing (2009-06-02)In this dissertation, advanced channel decoding techniques based on bit-level soft information are studied. Two main approaches are proposed: bit-level probabilistic iterative decoding and bit-level algebraic soft-decision ...

Wu, Zeyun (2011-02-22)The purpose of the inverse-transport problems that we address is to reconstruct the material distribution inside an unknown object undergoing a nondestructive evaluation. We assume that the object is subjected to incident ...
-
Chen, Xianjin (2009-05-15)We study computational theory and methods for finding multiple unstable solutions (corresponding to saddle points) to three types of nonlinear variational elliptic systems: cooperative, noncooperative, and Hamiltonian. We ...

Park, Eungyu (Texas A&M University, 2004-09-30)This dissertation is composed of three parts of major contributions. In Chapter II, we discuss analytical study of contaminant transport from a finite source in a finite-thickness aquifer. This chapter provides analytical ...

Chevarunotai, Natasha (2014-11-13)Modern downhole temperature measurements indicate that bottomhole fluid temperature could be significantly higher or lower than the original reservoir temperature, especially in ‘more challenging’ low-permeability reservoirs, ...
-
Park, Jincheol (2012-10-19)The Gaussian geostatistical model has been widely used in Bayesian modeling of spatial data. A core difficulty for this model is at inverting the n x n covariance matrix, where n is a sample size. The computational complexity ...

Bassey, Ogbonnaya (2020-12-01)Electric power systems face the risk of outages due to extreme weather events, cyber-attack, human errors, and other unforeseen circumstances. A power grid that is resilient to these unfortunate events has become a consistent ...
-
Lu, Zhenyu (2009-05-15)In this thesis we study a new type of pursuit-evasion game, which we call the herding problem. Unlike typical pursuit evasion games where the pursuer aims to catch or intercept the evader, the goal of the pursuer in this ...
-
Li, Meiqin (2017-12-07)We study computational theory and numerical methods for finding multiple unstable solutions (saddle points) for two types of nonlinear variational functionals. The first type consists of Gateaux differentiable (G-differentiable) ...
-
Chen, Chih-Hsuan (Texas A&M University. Libraries, 1994)The heat equation is a basic partial differential equation modelling heat conduction. Many numerical methods, such as finite-difference, finite-element, and boundary element methods, have been developed to solve the heat ...
-
Lee, Ho-Jin (Texas A&M University, 2005-11-01)Functional data refer to data which consist of observed functions or curves evaluated at a finite subset of some interval. In this dissertation, we discuss statistical analysis, especially classification and regression ...
-
Lee, Chak Shing (2016-07-29)Many science and engineering problems exhibit scale disparity and high contrast. The small scale features cannot be omitted in the physical models because they can affect the macroscopic behavior of the problems. However, ...
-
Jin, Lei (2009-05-15)In this dissertation, the generalized score tests based on weighted estimating equations are proposed for missing covariate data. Their properties, including the effects of nuisance functions on the forms of the test ...
-
Ye, Shuai (2016-12-09)Many engineering and scientific applications deal with models that have multiple spatial scales, and these scales can be non-separable. Many of these processes can exhibit nonlinearities and have a tight coupling with the ...
-
Wang, Shuguang (2009-05-15)The dissertation first investigates gravity wave generation and propagation from jets within idealized vortex dipoles using a nonhydrostatic mesoscale model. Several initially balanced and localized jets induced by vortex ...
-
Park, Jun Sur (2020-05-14)Simulation in media with multiple interacting continua is often challenging due to distinct properties of the continua, multiple scales and high contrast. Thus, some type of model reduction is required. One of the approaches ...

Ibrahim, Mazher Hassan (Texas A&M University, 2005-02-17)This dissertation presents several new techniques for the analysis of the long-term production performance of tight gas wells. The main objectives of this work are to determine pressure response function for long-term ...
