Designing a Real-time Strategy Game about Sustainable Energy Use
(2011-08-08)
This thesis documents the development of a video game about sustainable energy use that unites fun with learning. Many other educational games do not properly translate knowledge, facts, and lessons into the language of ...
A PLL Design Based on a Standing Wave Resonant Oscillator
(2011-10-21)
In this thesis, we present a new continuously variable high frequency standing wave oscillator
and demonstrate its use in generating the phase locked clock signal of a digital IC.
The ring based standing wave resonant ...
Estimation of Velocity Distribution and Suspended Sediment Discharge in Open Channels Using Entropy
(2011-08-08)
In hydraulics, velocity distribution is needed to determine flow characteristics, like discharge, sediment discharge, head loss, energy coefficient, moment coefficient, and scour. However, the complicated interaction between ...
Antecedent Geologic Controls on the Distribution of Oyster Reefs in Copano Bay, Texas
(2011-08-08)
Copano Bay is a shallow (< 2-3 m), microtidal estuary in south central Texas. In an effort to both determine the distribution as well as investigate the controls on the distribution of oyster reefs, a geophysical survey ...
Avian Response to Road Construction Noise with Emphasis on the Endangered Golden-cheeked Warbler
(2011-08-08)
Noise pollution can mask or distort bird songs, which inhibits mating success, predator detection, and parental response to begging calls. Road noise can cause lowered density and reproductive success in songbirds. I ...
Diffusion Preconditioner for Discontinuous Galerkin Transport Problems
(2011-08-08)
A simple Richardson iteration procedure converges slowly when applied to thick, diffusive problems with scattering ratios near unity. The current state of the art for overcoming this is to use a Krylov method with a diffusion ...
Nonlinear Analysis of a Two DOF Piecewise Linear Aeroelastic System
(2011-10-21)
The nonlinear dynamic analysis of aeroelastic systems is a topic that has been covered extensively in the literature. The two main sources of nonlinearities in such systems, structural and aerodynamic nonlinearities, have ...
Relationship between Frequency of RFID Tags and Its Ability to Penetrate Fresh Concrete
(2011-08-08)
The concrete maturity method can be utilized to determine in situ strength of concrete. It uses the temperature of concrete to determine a maturity index that can then be used to determine strength of concrete. However, ...
Mitigating Disuse Bone Loss: Role of Resistance Exercise and Beta-Adrenergic Signaling
(2011-08-08)
Mechanical loading is an integral component to maintaining bone mass during periods of disuse (i.e. bedrest or casting) or reduced weightbearing activity. Recent data has shown a direct relation between the sympathetic ...
Hope as a Strategy for Improving Student Achievement and Dissuading Repeat Pregnancy in Pregnant and Parenting Adolescents
(2011-08-08)
This dissertation examines the construct of hope and its ability to be taught to pregnant and parenting adolescents as a strategy to improve academic achievement and dissuade repeat adolescent pregnancy. A systemic review ...
