Dynamics of water use and responses to herbivory in the invasive reed, Arundo donax (L.)
(2010-07-14)
The first objective of this study was to investigate the role of an invasive grass
species, Arundo donax (L.), on the hydrologic cycle. At a site on the Rio Grande in
South Texas, we measured the gas exchange of carbon ...
Creating a Systems Engineering Approach for the Manual on Uniform Traffic Control Devices
(2010-07-14)
The Manual on Uniform Traffic Control Devices (MUTCD) establishes the basic principles for the design, selection, installation, operation, maintenance, and removal of traffic control devices (TCDs). The MUTCD indicates ...
Design of a 10 MHz Transimpedance Low-Pass Filter with Sharp Roll-Off for a Direct Conversion Wireless Receiver
(2010-07-14)
A fully-differential base-band transimpedance low-pass filter is designed for use
in a direct conversion wireless receiver. Existing base-band transimpedance amplifiers
(TIA) often utilize single-pole filters which do not ...
DEVELOPMENT IMPACT FEE ADOPTION AND ITS EFFECTS IN TEXAS
(2010-01-20)
The purpose of my thesis is to study what factors affect the adoption of impact fees in Texas and what effects impact fees have on city budgets. This research was done using two models. The first model looked at the adoption ...
Viscoelastic Analysis of Sandwich Beams Having Aluminum and Fiber-reinforced Polymer Skins with a Polystyrene Foam Core
(2010-07-14)
Sandwich beams are composite systems having high stiffness-to-weight and
strength-to-weight ratios and are used as light weight load bearing components. The use
of thin, strong skin sheets adhered to thicker, lightweight ...
Effects of Microbial Litter Amendments on Broiler Performance, Litter Quality and Ammonia Production
(2011-02-22)
The reuse of litter in broiler production can lead to litter pathogen buildup and high levels of ammonia in broiler housing, thus resulting in poor broiler performance. This study evaluated the effects of two microbial ...
Tearable Cloth
(2010-01-16)
This document proposes modifications to an established cloth simulation algorithm to
allow for stretch deformation and tearing of simulated cloth in computer-generated
imagery. Previous research is presented, followed by ...
A Comparison of Least-Squares Finite Element Models with the Conventional Finite Element Models of Problems in Heat Transfer and Fluid Mechanics
(2010-07-14)
In this thesis, least-squares based finite element models (LSFEM) for the Poisson equation and Navier-Stokes equation are presented. The least-squares method is simple, general and reliable. Least-squares formulations offer ...
Performance Analysis of Dispersed Spectrum Cognitive Radio Systems
(2011-02-22)
Dispersed spectrum cognitive radio systems represent a promising approach to exploit the utilization of spectral resources to full extent. Therefore, the performance analysis of such systems is conducted in this research. ...
Structural Locking in a Nastic Actuated Shaped-Changing Beam
(2010-07-14)
This thesis endeavors to develop a new locking method for a twisted morphing wing spar. The conventional wing has to have hinges and a discontinuous surface. These cause air separation that decreases aerodynamic performance. ...
