Modeling of crack tip high inertia zone in dynamic brittle fracture
(Texas A&M University, 2007-09-17)
A phenomenological cohesive term is proposed and added to an existing
cohesive constitutive law (by Roy and Dodds) to model the crack tip high inertia region
proposed by Gao. The new term is attributed to fracture mechanisms ...
Monomethylmercury concentrations on the eastern Texas-Louisiana shelf during the formation, peak, and disappearance of hypoxia
(Texas A&M University, 2007-09-17)
A study of monomethylmercury (MMHg) concentrations in the water and sediment of
the hypoxic zone in the northeastern Gulf of Mexico was conducted on several cruises
between April 2004 and May 2005. Surface water MMHg ...
Dual Coding Theory and Chinese: Recall of Concrete and Abstract Sentences in Chinese-English Bilinguals
(2010-10-12)
Theories of reading have seldom been examined across orthographies. In the
present study, Dual Coding Theory (DCT), a general theory of cognition applied to
literacy, was applied to Chinese sentences to investigate the ...
High-silica zeolite nucleation from clear solutions
(Texas A&M University, 2006-04-12)
Understanding the mechanism of zeolite nucleation and crystallization will
enable the zeolite science community to tune zeolite properties during synthesis in
order to accommodate the purposes of various applications. Thus ...
A Climatology of Tropical Anvil and Its Relationship to the Large-Scale Circulation
(2011-02-22)
This dissertation uses multiple tools to investigate tropical anvil, i.e., thick, non-precipitating cloud associated with deep convection with the main objectives to provide a climatology of tropics-wide anvil properties ...
Ambient pH signaling influences phosphate transport in Neurospora crassa
(Texas A&M University, 2007-04-25)
In the course of our efforts to resolve Pi transport mechanisms in the model fungus
Neurospora crassa we identified a null mutant, par-1, that displays enhanced Pi
transport activity specifically under alkaline growth ...
Sequence stratigraphic controls of hydrocarbon reservoir architecture - case study of Late Permian (Guadalupian) Queen Formation, Means Field, Andrews County, Texas.
(Texas A&M University, 2004-09-30)
The late Permian Queen Formation (115 m thick) is a succession of mixed clastics, carbonates and evaporites deposited in the northeastern margin of Central Basin Platform of the Permian Basin, west Texas, USA. Depositional ...
The aesthetic principles of soundscape in architectural design and built environment
(Texas A&M University, 2004-09-30)
This thesis is an attempt to establish a practical way for architectural designers to take advantage of the relationship between soundscape and architectural aesthetics. The whole study aides in providing a structural ...
Autonomous robotic wheelchair with collision-avoidance navigation
(Texas A&M University, 2008-10-10)
The objective of this research is to demonstrate a robotic wheelchair moving in an
unknown environment with collision-avoidance navigation. A real-time path-planning
algorithm was implemented by detecting the range to ...
Design of high speed low voltage data converters for UWB communication systems
(Texas A&M University, 2006-08-16)
For A/D converters in ultra-wideband (UWB) communication systems, the flash
A/D type is commonly used because of its fast speed and simple architecture. However,
the number of comparators in a flash A/D converter exponentially ...
