Second order accurate variance estimation in poststratified two-stage sampling
(Texas A&M University, 2007-09-17)
We proposed new variance estimators for the poststratified estimator of the population
total in two-stage sampling. The linearization or Taylor series variance estimator
and the jackknife linearization variance estimator ...
Spectroscopic investigations of the vibrational potential energy surfaces in electronic ground and excited states
(Texas A&M University, 2007-09-17)
The vibrational potential energy surfaces in electronic ground and excited states of several ring molecules were investigated using several different spectroscopic methods, including far-infrared (IR), Raman, ultraviolet ...
Urban fox squirrel ecology and management
(Texas A&M University, 2007-09-17)
I studied the habitat selection, survival, and anti-predator behaviors of the fox squirrel (Siurus niger) across the urban-rural gradient in College Station, Texas. From two years of tracking the radio locations of 82 fox ...
Bayesian variable selection in clustering via dirichlet process mixture models
(Texas A&M University, 2007-09-17)
The increased collection of high-dimensional data in various fields has raised a strong
interest in clustering algorithms and variable selection procedures. In this disserta-
tion, I propose a model-based method that ...
Studies of the relationship of protein structure to regulation and catalysis in tyrosine hydroxylase
(Texas A&M University, 2007-09-17)
Tyrosine hydroxylase (TyrH) catalyzes the rate-limiting step in the synthesis of the catecholamine neurotransmitters dopamine, epinephrine, and norepinephrine. Phosphorylation of Ser40 of rat TyrH activates the enzyme by ...
Regulation of vascular endothelial growth factor receptor-2 in pancreatic and breast cancer cells by Sp proteins
(Texas A&M University, 2007-09-17)
Vascular endothelial growth factor receptor-2 (VEGFR2) is a key
angiogenic factor, and angiogenesis is an important physiological process
associated with neovascularization, growth, and metastasis of many different
tumors. ...
Transportation barriers to health care: assessing the Texas Medicaid program
(Texas A&M University, 2007-09-17)
Transportation is frequently cited as a barrier to health care, but rarely have
researchers analyzed the problems in depth. The purpose of this study was to assess the role
transportation plays in the utilization of ...
High frequency and high dynamic range continuous time filters
(Texas A&M University, 2007-09-17)
Many modern communication systems use orthogonal frequency division
multiplexing (OFDM) and discrete multi-tone (DMT) as modulation schemes where
high data rates are transmitted over a wide frequency band in multiple ...
Incorporating user design preferences into multi-objective roof truss optimization
(Texas A&M University, 2007-09-17)
Automated systems for large-span roof truss optimization provide engineers with
the flexibility to consider multiple alternatives during conceptual design. This
investigation extends previous work on multi-objective roof ...
Development of methods to quantify bitumen-aggregate adhesion and loss of adhesion due to water
(Texas A&M University, 2007-09-17)
Moisture induced damage of hot mix asphalt pavements has a significant
economic impact in terms of excessive maintenance and rehabilitation costs. The
moisture sensitivity of an asphalt mix depends on the combined effects ...
