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 ...
An innovative approach to predicting meat tenderness using biomechanical properties of meat
(Texas A&M University, 2007-09-17)
Biomechanical compression studies at different temperatures were conducted to
correlate the biomechanical response of raw bovine Longissimus dorsi muscles varying
in USDA Quality Grade with overall sensory tenderness scores. ...
Assessing the economic revitalization impact of urban design improvements: the Texas Main Street Program
(Texas A&M University, 2007-09-17)
The relationship between urban design and economic activity is seldom studied through
empirical studies with a large number of cases due, in part, to the implicit and intangible
nature of design. This study was intended ...
When things go wrong at work: expressions of organizational dissent as interpersonal influence
(Texas A&M University, 2007-09-17)
This dissertation examines the types of messages used for organizational dissent,
and argues for connections between dissent messages, choice of audience and influence
goals. The organizational dissent literature has ...
