A tale of two cacti: studies in Astrophytum asterias and Lophophora williamsii
(Texas A&M University, 2007-04-25)
Astrophytum asterias (star cactus) and Lophophora williamsii (peyote) are sympatric species in the Tamaulipecan thornscrub of South Texas and adjacent Mexico. Peyote has been excavated from two archaeological sites: Shumla ...
The impact of CEO option grants on firm value: determinants of the effectiveness of option grants
(Texas A&M University, 2007-04-25)
The significance of stock options as a component of executive compensation
has fluctuated dramatically over the past decade. The purpose of this study is to investigate
determinants of the effectiveness of stock option ...
Numerical simulation of flow and heat transfer of internal cooling passage in gas turbine blade
(Texas A&M University, 2007-04-25)
A computational study of three-dimensional turbulent flow and heat transfer was
performed in four types of rotating channels.
The first type is a rotating rectangular channel with V-shaped ribs. The channel
aspect ratio ...
Kinetic isotope effects, dynamic effects, and mechanistic studies of organic reactions
(Texas A&M University, 2007-04-25)
Several organic reactions that could potentially involve coarctate transition states
were investigated by a combination of experimental and theoretical studies.
In the thermal fragmentation of âÂÂ-1,3,4-oxadiazolines, ...
Fault simulation and test generation for small delay faults
(Texas A&M University, 2007-04-25)
Delay faults are an increasingly important test challenge. Traditional delay fault
models are incomplete in that they model only a subset of delay defect behaviors. To
solve this problem, a more realistic delay fault model ...
Effect of microstructure of closed cell foam on strength and effective stiffness
(Texas A&M University, 2007-04-25)
This research is concerned with the modeling and failure analysis of closed cell
foam with various scales of microstructure that is disordered due to defects. This foam
material is used for the forward bipod closeout on ...
Comparative study of social economic differences in relation to technology competency expectations as perceived by business and educational leaders
(Texas A&M University, 2007-04-25)
This qualitative study investigated the urgent need for business and public schools to design a comprehensive system for preparing all students for a technological workplace, while giving them the necessary academic ...
The dynamic, resource-constrained shortest path problem on an acyclic graph with application in column generation and literature review on sequence-dependent scheduling
(Texas A&M University, 2007-04-25)
This dissertation discusses two independent topics: a resource-constrained shortest-path problem
(RCSP) and a literature review on scheduling problems involving sequence-dependent setup
(SDS) times (costs).
RCSP is often ...
High school students' perceptions of and attitudes toward globalization: an analysis of international baccalaureate students in Estado de Mexico, Mexico, and Texas, U.S.A.
(Texas A&M University, 2007-04-25)
As the last few decades have seen a proliferation of debate concerning todayâÂÂs
international system referred to as âÂÂglobalization,â education has seen an exponential
rise in curriculum (such as that promoted ...
