Kim, Young Sook (Texas A&M University. Libraries, 1990)Existence of a weak solution for some boundary value problems of mixed and hyperbolic types is proved by constructing multipliers which satisfy the multiplier inequalities. The nature of a singularity is then examined by ...
-
Terzioglu, Fatma (2018-02-16)In this dissertation, we focus on analytic and numerical inversion of an integral transform (cone or Compton transform) that maps a function to its integrals over conical surfaces with a weight equal to some power of the ...
-
Doraiswamy, Srikrishna (2012-02-14)The aim of this work is to present a model for the superelastic response of Shape Memory Alloys (SMAs) by developing a Preisach Model with thermodynamics basis. The special features of SMA superelastic response is useful ...
-
Hur, Sun (Texas A&M University. Libraries, 1993)The appropriateness of independence assumptions in queueing theory should be doubted at least in applications such as modem manufacturing or telecommunication systems. Simplifying independence assumptions may lead to a ...
-
Swinney, Mathew Wayne (2015-12-16)A terrorist attack using an improvised nuclear device is one of the most serious dangers facing the United States. The work presented here is an effort to improve nuclear deterrence by developing a methodology to attribute ...
-
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 ...
-
Bui, Dat Duc (Texas A&M University. Libraries, 1993)The study of the inverse scattering problem for electromagnetic waves, especially under consideration of such realistic effects as spatial inhomogeniety, dispersion, dissipativity and multiple spatial dimensions, is based ...

Baines, Weston Theodore Cotter (2022-05-18)Several tasks in the fields of medicine and homeland security require the ability to detect weak signals under stymieing conditions. For instance, in medical imaging single photon emission computed tomography can be used ...
-
Zhang, Zhidong (2017-06-08)By Fick’s laws of diffusion, in the classical diffusion process, the mean square path ‹x2› is proportional to the time t as t →∞,. However, in practice, some anomalous diffusion processes may occur, in which the relation ...
-
Zuo, Lihua (2013-06-21)In recent decades, significant interest, based on physics and engineering applications, has developed on so-called anomalous diffusion processes that possess different spread functions with classical ones. The resulting ...
-
Collins, Charles R. (1984)This paper considers models of physical phenomena, in particular models from population dynamics. The main model of concern is a combination of two previously developed models: the model of non-linear age dependent population ...
-
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, ...
-
Lei, Wenyu (2018-05-22)The negative powers of an elliptic operator can be approximated via its Dunford-Taylor integral representation, i.e. we approximate the Dunford-Taylor integral with an exponential convergent sinc quadrature scheme and ...
-
Zedric, Robert Michael (2022-11-16)Radiation effects on avalanche photodiodes (APDs) are important to understand when deploying these devices in satellites, high energy physics, military, and nuclear safeguards applications. Radiation can compromise the ...

Alahmadi, Hasan Ali H. (2010-10-12)Fractured reservoirs have been traditionally idealized using dual-porosity models. In these models, all matrix and fractures systems have identical properties. However, it is not uncommon for naturally fractured reservoirs ...
