In the area that is now Saguaro National Park East, grazing began in the 1880's. Because of the impact to the iconic saguaro cactus as well as all palatable plant species in the area, ecological damage in the park were determined to be so great that anti-grazing conservationists challenged the...
The theory behind magnetohydrodynamics (MHD) is utilized to present a 3-D solution to how the induced magnetic field changes with respect to time. Several MHD-based assump- tions are made to simplify the coupling of Maxwell’s equations with two constitutive laws and Ohm’s law. The velocity field is assumed to be...
Facial recognition has become increasingly important in recent years, due to the wide range of applications it has in fields such as security, surveillance, and human-computer interaction. Three popular methods for facial recognition are the Principal Component Analysis (PCA), Karhunen-Loeve Expansions, which is fundamentally a continuous form of PCA but...
Caregiving circumstances frequently evoke high levels of stress for caregivers and have consistently been linked to adverse psychological and physical health consequences. Within the caregiving literature, researchers have sought to answer questions about why some individuals seem to be particularly vulnerable to the well-established deleterious consequences of caregiving stress. Several...
This research addressed the role of educational technology associations as change agents within education with particular emphasis on issues of advocacy and leadership. Using a poststructural feminist lens and the metaphor of interview and analysis as storytelling, it explored the perspectives of nineteen individuals belonging to a national level educational...
The integumental histology of Taricha granulosa (Skilton) has
been investigated with special attention being given to the seasonal
variations associated with terrestrial and aquatic habitats.
The epidermis consists of a stratified squamous epithelium,
four to seven cell layers thick, with one to two layers being cornified.
The dermis is composed...
Within this dissertation, we develop tools and techniques to demonstrate the feasibility of real-time optimization of a magnetohydrodynamics generator. To ease computational complexity, we work on the kinematic magnetohydrodynamic system, prescribing the fluid-flow and model the material response of the system through an updated Generalized Ohm’s law. We focus on...
