Arduino Based Hybrid MPPT Controller for Wind and Solar

Description: Renewable power systems are becoming more affordable and provide better options than fossil-fuel generation, for not only the environment, but a benefit of a reduced cost of operation. Methods to optimize charging batteries from renewable technologies is an important subject for off-grid and micro-grids, and is becoming more relevant for larger installations. Overcharging or undercharging the battery can result in failure and reduction of battery life. The Arduino hybrid MPPT controller takes t… more

How Does It Feel to be Creative? A Phenomenological Investigation of the Creative Experience in Kinetic Places

Description: How does it feel to be creative? Such a question, when approached from a phenomenological perspective, reveals new understandings about the embodied experience of creativity, and how it feels as it is being lived. This investigation begins with a provocative contrast of two environments where creativity is thought to manifest itself: school art classrooms, where creativity is often legislated from an authority figure, and New Orleans Second Line parades, where creativity is organically and kin… more

When to Say It: Establishing a Verbal Cue

Description: Dog trainers sometimes teach verbal cues by saying the cue as the dog is performing the desired behavior. However, there is disagreement about when to say the cue. In this study, a pet dog was trained to go to three different apparatus, the cue for each of which was given at a different time, in a multi-element design. The cue "hoop" was given just as the dog began to move to the hoop apparatus. The cue "carrier" was given as the dog was stepping into the carrier apparatus. The cue "platform" w… more

Musical Priming and Operant Selection

Description: Language is a cultural construct, and the relationship between words is taught. Priming research has long investigated the relationship between related and unrelated words. Similar research has been seen in music relationships, but most of these investigate harmonic relations despite the melodic relationship being the one listeners are mostly likely to describe. Further, these studies typically measure existing relationships and do not attempt to teach a new relationship, nothing that most adu… more

Shear and Bending Strength of Cold-Formed Steel Solid Wall Panels Using Corrugated Steel Sheets for Mobile Shelters

Description: The objective of this thesis is to determine if the single sided resistance spot weld (RSW) can be used as a feasible connection method for cold formed steel (CFS) shear walls subject to lateral force of either seismic or wind loads on mobile shelters. The research consisted of three phases which include: a design as a 3D BIM model, connection tests of the resistance spot weld, and full-scale testing of the designed solid wall panels. The shear wall testing was conducted on specimens with both … more

Modeling of High Strain Rate Compression of Austenitic Shape Memory Alloys

Description: Shape memory alloys (SMAs) exhibit the ability to absorb large dynamic loads and, therefore, are excellent candidates for structural components where impact loading is expected. Compared to the large amount of research on the shape memory effect and/or pseudoelasticity of polycrystalline SMAs under quasi-static loading conditions, studies on dynamic loading are limited. Experimental research shows an apparent difference between the quasi-static and high strain rate deformation of SMAs. Research… more

Analysis of Heat Transfer Enhancement in Channel Flow through Flow-Induced Vibration

Description: In this research, an elastic cylinder that utilized vortex-induced vibration (VIV) was applied to improve convective heat transfer rates by disrupting the thermal boundary layer. Rigid and elastic cylinders were placed across a fluid channel. Vortex shedding around the cylinder led to the periodic vibration of the cylinder. As a result, the flow-structure interaction (FSI) increased the disruption of the thermal boundary layer, and therefore, improved the mixing process at the boundary. This … more

Co-Occurrence of Rape Myth Acceptance and Intolerant Attitudes in a Military Sample

Description: Sexual trauma within the military is a widespread issue, and rape myth acceptance has been shown to contribute to its prevalence. Given that the military culture has been shown to lend itself to hypermasculinity and traditional gender role adherence, both of which facilitate aggression toward women, this effect warrants investigation within a military sample. The present study replicated and expanded upon Aosved and Long's (2006) study examining 85 veteran and active duty military members' resp… more

Teaching Observational Learning to Children with Autism: An In-vivo and Video-Model Assessment

Description: Observational learning (OL) occurs when an individual contacts reinforcement as a direct result of discriminating the observed consequences of other individuals' responses. Individuals with autism spectrum disorder (ASD) may have deficits in observational learning and previous research has demonstrated that teaching a series of prerequisite skills (i.e., attending, imitation, delayed imitation, and consequence discrimination) can result in observational learning. We sequentially taught these pr… more

Spectrum Analysis and Prediction Using Long Short Term Memory Neural Networks and Cognitive Radios

Description: One statement that we can make with absolute certainty in our current time is that wireless communication is now the standard and the de-facto type of communication. Cognitive radios are able to interpret the frequency spectrum and adapt. The aim of this work is to be able to predict whether a frequency channel is going to be busy or free in a specific time located in the future. To do this, the problem is modeled as a time series problem where each usage of a channel is treated as a sequence o… more

Investigating Factors that Affect Faculty Attitudes towards Participation in Open Access Institutional Repositories

Description: Open access institutional repositories (OA IRs) are electronic systems that capture, preserve, and provide access to the scholarly digital work of an institution. As a new channel of scholarly communications IRs offer faculty a new way to disseminate their work to a wider audience, which in turn can increase the visibility to their work and impact factors, and at the same time increase institutions prestige and value. However, despite the increased popularity of IRs in numbers, research shows … more

The Influence of Disease Mapping Methods on Spatial Patterns and Neighborhood Characteristics for Health Risk

Description: This thesis addresses three interrelated challenges of disease mapping and contributes a new approach for improving visualization of disease burdens to enhance disease surveillance systems. First, it determines an appropriate threshold choice (smoothing parameter) for the adaptive kernel density estimation (KDE) in disease mapping. The results show that the appropriate threshold value depends on the characteristics of data, and bandwidth selector algorithms can be used to guide such decisions a… more

Maximal Proposition, Environmental Melodrama, and the Rhetoric of Local Movements: A Study of The Anti-Fracking Movement in Denton, Texas

Description: The environmental problems associated with the boom in hydraulic fracturing or "fracking," such as anthropogenic earthquakes and groundwater contamination, have motivated some citizens living in affected areas such as Denton, Texas to form movements with the goal of imposing greater regulation on the industry. As responses to an environmental threat that is localized and yet mobile, these anti-fracking movements must construct rhetorical appeals with complicated relationships to place. In this … more
