SHAPE DESIGN SENSITIVITY ANALYSIS AND OPTIMIZATION FOR 2-D STRUCTURAL COMPONENTS UNDER MIXED MODE FRACTURE USING EXTENDED FINITE ELEMENT METHOD AND LEVEL SET METHOD
(2009)
Weight and service life are often the two most important considerations in the design of structural components. This research incorporates a novel crack propagation analysis technique into shape optimization framework to ...
TOWARD A MORE CLARIFIED DETECTIVE QUANTUM EFFICIENCY METHODOLOGY: STUDY OF THE DQE THEORY AND APPLICATIONS
(2009)
Detective quantum efficiency (DQE) is widely accepted as the golden rule to objectively evaluate the performance of x-ray imaging systems. It provides a comprehensive characterization of an x-ray imaging system, because ...
AN ETHNOHISTORY OF THE AMERICAN INDIAN EXPOSITION AT ANADARKO, OKLAHOMA: 1932-2003
(2009)
The American Indian Exposition achieved unprecedented national prominence between its founding in 1932 and its "Glory Years" in the 1940s and 1950s. As a result, Anadarko was proclaimed as the Indian capital of the United ...
A COUPLED HYDRAULIC-MECHANICAL ELASTOPLASTIC CONSTITUTIVE MODEL FOR UNSATURATED SANDS AND SILTS
(2009)
Unsaturated soils are three-phase porous media consisting of a solid skeleton, pore water, and pore air. It is well known that the behavior of unsaturated soils is influenced heavily by the matric suction (pore air ...
Bockstein Basis and Resolution Theorems in Extension Theory
(2009)
Resolution refers to a map (a continuous function) between topological spaces, where the domain is in some way better than the range, and the fibers (point preimages) meet certain requirements. We will be interested in the ...
Analysis of Spatial Uncertainty in LiDAR-derived Building Data and Uncertainty Propagation in Modeling of Urban Atmospheric Dispersion
(2009)
Results of environmental models (EMs) are often used to assist decision making. However, EM outcomes vary significantly with different input data, model parameters and model assumptions. Therefore, informed decision making ...
DEVIATIONS FROM THE NORM: VITAL SIGNS AFFECTING ATTRIBUTIONS OF ORGANIZATIONAL CITIZENSHIP BEHAVIOR MOTIVES
(2009)
Since the organizational citizenship behavior (OCB) construct was introduced twenty-five years ago (Bateman & Organ, 1983; Smith, Organ, & Near, 1983), researchers have directed a great deal of research effort toward ...
EXAMINING THE COMPLEXITIES OF EMOTION REGULATION IN THE WORKPLACE: THE DEVELOPMENT AND VALIDATION OF THE WORKPLACE EMOTION REGULATION PREFERENCE INVENTORY
(2009)
The purpose of this study is to examine how several categories of emotion regulation strategies are related to satisfaction and performance outcomes. A measure of workplace emotion regulation was developed and validated ...
Modeling of Integral Abutment Bridges Considering Soil-Structure Interaction Effects
(2009)
Soil-structure interaction problems are both highly interesting and highly complex. To model soil-structure interaction problems accurately, the constitutive parts (i.e. foundations, soils, and superstructures) must be ...
Examination of High School Transition Program Variables Associated with Successful Outcomes
(2009)
This dissertation study investigated secondary transition programs throughout New Mexico in order to identify the extent of their services and research suggested best practices within high schools. Educators, including ...
