(2012-12-10)In the past decades, considerable effort has been put into developing high resolution geological models for oil and gas reservoirs. Although the growth of computational power is rapid, the static model size still exceeds ...
-
(2012-10-19)In this dissertation, we develop multiscale finite element methods and uncertainty quantification technique for Richards' equation, a mathematical model to describe fluid flow in unsaturated porous media. Both coarse-level ...
-
(2015-11-06)Anisotropy occurs in a wide range of applications. Examples include porous media, composite materials, heat transfer, and other fields in science and engineering. Due to the anisotropy, the physical property could vary ...
-
(2021-07-08)Soil moisture (SM) and evapotranspiration (ET) are key climate variables governing environmental processes from local to global scales. The global burgeoning of SM and ET datasets holds a significant potential in improving ...
-
(2012-10-19)Reservoir model calibration to production data, also known as history matching, is an essential tool for the prediction of fluid displacement patterns and related decisions concerning reservoir management and field ...
-
(2020-04-21)Here, a number of analytic and computational models are utilized to study the transient thermomechanical response of heterogeneous materials. The models account for thermal stresses generated by incompatibilities in thermal ...
-
(2012-02-14)In this study, the performances of the optical sensors and instruments carried on both ground-based and airborne platforms were evaluated for monitoring crop growing status, detecting the vegetation response to aerial ...

Multiterminal source coding: sum-rate loss, code designs, and applications to video sensor networks (2009-05-15)Driven by a host of emerging applications (e.g., sensor networks and wireless video), distributed source coding (i.e., Slepian-Wolf coding, Wyner-Ziv coding and various other forms of multiterminal source coding), has ...
-
(2012-10-19)Multiterminal (MT) video coding is a practical application of the MT source coding theory. For MT source coding theory, two problems associated with achievable rate regions are well investigated into in this thesis: a new ...
-
(2017-07-28)To take advantage of the processing power in the Chip Multiprocessors design, applications must be divided into semi-independent processes that can run concur- rently on multiple cores within a system. Therefore, programmers ...
-
(2010-10-12)The rapid growth of peer-to-peer (P2P) networks in the past few years has brought with it increases in transit cost to Internet Service Providers (ISPs), as peers exchange large amounts of traffic across ISP boundaries. ...
-
(2023-05-03)Underactuated mechanical systems (UMS) represent a significant group of mechanical systems with fewer independent control actuators than degrees of freedom (DOF). These systems are considered more efficient and lightweight ...
-
(2013-11-11)The knowledge of speed and headway distributions is essential in microscopic traffic flow studies because speed and headway are both fundamental microscopic characteristics of traffic flow. For microscopic ...
-
(2022-07-10)This dissertation contains four projects involving applications of truncated multivariate normal sampling and multivariate normal probability estimation for linearly constrained domains. These two problems have a large ...
-
(2020-04-13)This research aims to describe the evolution of platoon vehicle speed distribution parameters and platoon characteristics change quantitatively, and utilize this information to develop advanced signal timing strategies for ...
-
(2012-02-14)This dissertation is composed of three articles describing novel approaches for analysis and modeling using multivariate skew-normal and skew-t distributions in econometrics and environmetrics. In the first article we ...
-
(Texas A&M University, 2007-04-25)Mixing of fluids at the microscale poses a variety of challenges, many of which arise from the fact that molecular diffusion is the dominant transport mechanism in the laminar flow regime. The unfavorable combination of ...
-
(2022-06-28)This dissertation reports mechanistic investigations of selected technologies employed for physicochemical treatment and reuse of industrial and municipal wastewater. The first part investigates simultaneous biological, ...
-
(2016-12-06)This dissertation study tested the hypothesis that greater political fragmentation in a metropolitan area increases the degree of residential segregation between non-Hispanic whites and non-Hispanic blacks. The questions ...
-
(2009-05-15)This research addresses the question of what explains municipal performance in terms of delivering social services and fiscal performance. While the existing literature explains governmental performance with political, ...
