Development Of A Mathematical Model For 3d Reconstruction Of Target Objects By Photogrammetry, Keith F. Blonquist
Development Of A Mathematical Model For 3d Reconstruction Of Target Objects By Photogrammetry, Keith F. Blonquist
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This thesis outlines the development of a mathematical model which can be used to perform 3D reconstruction of a target object from surveillance images. 3D reconstruction is a common procedure in photogrammetry, but performing 3D reconstruction from surveillance images can be more difficult than typical photogrammetry applications.
Surveillance images are generally captured in an unsystematic manner because there is no control over the target that is being photographed. Surveillance images can have a wide variety of fields of view, are often captured with uncalibrated cameras, and typically the targets are objects for which there is no other a priori information. …
Effects Of Olfactory And Visual Predators On Nest Success And Nest-Site Selection Of Waterfowl In North Dakota., Jennifer S. Borgo
Effects Of Olfactory And Visual Predators On Nest Success And Nest-Site Selection Of Waterfowl In North Dakota., Jennifer S. Borgo
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Selecting a nest site is an important decision for waterfowl. Because most nest failure is due to depredation, the primary selective pressure in choosing a nest site should be to reduce depredation risk. This task is difficult because predators use differing tactics to locate nests, such as olfactory or visual cues. I investigated several components of waterfowl nest-site selection and success on sites with shelterbelts (planted tree-rows) in North Dakota, during the 2006 and 2007 nesting seasons.
I found that meteorological conditions impacted nest depredation; artificial nests were more likely to be depredated when either temperature or dew point was …
Uptake And Release Kinetics Of Sulfolane By Cattail Plants, Tiffany Leo
Uptake And Release Kinetics Of Sulfolane By Cattail Plants, Tiffany Leo
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Sulfolane (tetrahydrothiophene 1,1-dioxide, C4H8O2S) is a highly water-soluble, non-ionizable, organic compound used along with diisopropanolamine in the Sulfinol™️ process to remove hydrogen sulfide from natural gas. Sulfolane has been identified in wetland vegetation near a sour gas processing facility in Alberta, Canada, and extensive uptake of sulfolane by cattails has also been demonstrated in a laboratory environment. Consequently, it has been suggested that plants could play an important role in the natural attenuation of sulfolane in contaminated wetlands. This assumes that the sulfolane is metabolized and/or sequestered in the plant and not released back …

Integrating Surface And Sub Surface Flow Models Of Different Spatial And Temporal Scales Using Potential Coupling Interfaces, Alphonce Chenjerayi Guzha
Integrating Surface And Sub Surface Flow Models Of Different Spatial And Temporal Scales Using Potential Coupling Interfaces, Alphonce Chenjerayi Guzha
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The main objective of this research was to develop and utilize a coupled surface water groundwater model to simulate hydrological responses of watersheds. This was achieved by coupling the U.S. Geological Survey (USGS) groundwater flow model, MODFLOW, and the rainfall runoff model, TOPMODEL, in one case study and coupling MODFLOW with a networked version of TOPMODEL called TOPNET in another case study. The model coupling was achieved using the InCouple approach, which utilizes Potential Coupling Interfaces (PCIs) that are abstractions from model flow diagrams that expose only those aspects of a model relevant to coupling. Coupling the rainfall-runoff models to …
Variational Asymptotic Micromechanics Modeling Of Composite Materials, Tian Tang
Variational Asymptotic Micromechanics Modeling Of Composite Materials, Tian Tang
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The issue of accurately determining the effective properties of composite materials has received the attention of numerous researchers in the last few decades and continues to be in the forefront of material research. Micromechanics models have been proven to be very useful tools for design and analysis of composite materials. In the present work, a versatile micromechanics modeling framework, namely, the Variational Asymptotic Method for Unit Cell Homogenization (VAMUCH), has been invented and various micromechancis models have been constructed in light of this novel framework. Considering the periodicity as a small parameter, we can …
The Effects Of A Self-Monitoring Package Using A Tactile Cueing Device On Student On-Task Behavior In Special Education And General Education Settings, Elizabeth Johnson
The Effects Of A Self-Monitoring Package Using A Tactile Cueing Device On Student On-Task Behavior In Special Education And General Education Settings, Elizabeth Johnson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Research has shown that self-monitoring can be effective in different settings and with a range of students as well as problem behaviors. However, teachers who use self-monitoring techniques have difficulties in using an effective cueing system as well as generalizing the newly acquired skill into the general education classroom. This study extends the literature by utilizing a tactile cueing device to increase the percentage of intervals of on-task behavior as well as increasing the intervals of on-task behavior in an inclusive general education classroom setting.
The Genetics Of Colonization In Two Amphibian Species After The 1980 Eruption Of Mount St. Helens, Kristin Ann Bakkegard
The Genetics Of Colonization In Two Amphibian Species After The 1980 Eruption Of Mount St. Helens, Kristin Ann Bakkegard
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The genetics of colonization is understudied in salamanders but has large conservation implications as new habitats are formed or restored to their previous condition. The 1980 eruption of Mount St. Helens provided a natural experiment to study the genetic effects of a large infrequent environmental disturbance on two species of salamander, Taricha granulosa (Rough-skinned newt) and Ambystoma gracile (Northwestern salamander). Both these species breed in ponds, and are thought to exhibit high breeding site fidelity and low vagility. I designated three treatments based on the effects of the eruption: new ponds (created by the eruption, immigrants only), recovery lakes (in …
The Effect Of Climate Change On The Hydrology Of A Mountainous Catchment In The Western United States: A Case Study At Reynolds Creek, Idaho, Anurag Nayak
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This research is focused on understanding the sensitivity of a hydrologic regime at the Reynolds Creek Experimental Watershed (RCEW), a snowmelt dominated semi-arid mountain basin located in southwest Idaho, to climate warming.
Climate data, collected during 1962 to 2006 at many locations in the RCEW, was carefully checked, preprocessed, and corrected for errors and noise signals introduced by the instrument malfunctioning and extreme weather conditions. An Automated Precipitation Correction Program (APCP) was developed to remove mechanical errors from the weighing-recording bucket type precipitation gauge measurements. APCP produces comparable results to the manual techniques but a degree faster (few minutes against …

Sources And Source Processes Of Organic Nitrogen Aerosols In The Atmosphere, Mark E. Erupe
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The research in this dissertation explored the sources and chemistry of organic nitrogen aerosols in the atmosphere. Two approaches were employed: field measurements and laboratory experiments. In order to characterize atmospheric aerosol, two ambient studies were conducted in Cache Valley in Northern Utah during strong winter inversions of 2004 and 2005. The economy of this region is heavily dependent on agriculture. There is also a fast growing urban population. Urban and agricultural emissions, aided by the valley geography and meteorology, led to high concentrations of fine particles that often exceeded the national ambient air quality standards. Aerosol composition was dominated …

Longitudinal And Reciprocal Effects Of Ethnic Identity And Experiences Of Discrimination On Psychosocial Adjustment Of Navajo (Diné) Adolescents, Matthew D. Jones
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study examined the relationships among ethnic identity, cultural identity, experiences of discrimination, their interactions, and their effects on various psychosocial outcomes (self-esteem, depression, sense of school membership, social functioning, substance abuse, substance related problems, delinquent behaviors, and grade point average [GPA]). Data were collected twice over a 2-year period.
Change across time was observed in male adolescents' experiences of discrimination. Affirmation and belonging to Navajo culture was the strongest protective predictor at Time 1, but at Time 2 less consistent patterns of association emerged. Also at Time 2, experiences of discrimination emerged as a powerful negative predictor of psychosocial …
Henry Viii: Supremacy, Religion, And The Anabaptists, Joel Martin Gillaspie
Henry Viii: Supremacy, Religion, And The Anabaptists, Joel Martin Gillaspie
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In 1534, the English Parliament passed the Act of Supremacy. This effectively stripped all of the authority the Pope held in England and gave it to Henry VIII. Also because of the Act of Supremacy Henry VIII gained a new title: Supreme Head of the Church of England. However, there was a problem. The Act of Supremacy only vaguely defined the new powers that had been given to the King. Consequently, what exactly his new powers were and their limits had to be established. The other issue that had to be dealt with was the establishment of the canons of …
Agent-Organized Network Coalition Formation, Levi L. Barton
Agent-Organized Network Coalition Formation, Levi L. Barton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This thesis presents work based on modeling multi-agent coalition formation in an agent organized network. Agents choose which agents to connect with in the network. Tasks are periodically introduced into the network. Each task is defined by a set of skills that agents must fill. Agents form a coalition to complete a task by either joining an existing coalition a network neighbor belongs to, or by proposing a new coalition for a task no agents have proposed a coalition for. We introduce task patience and strategic task selection and show that they improve the number of successful coalitions agents form. …
Hydrogen Production By Anaerobic Fermentation Using Agricultural And Food Processing Wastes Utilizing A Two-Stage Digestion System, Reese S. Thompson
Hydrogen Production By Anaerobic Fermentation Using Agricultural And Food Processing Wastes Utilizing A Two-Stage Digestion System, Reese S. Thompson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Hydrogen production by means of anaerobic fermentation was researched utilizing three different substrates. Synthetic wastewater, dairy manure, and cheese whey were combined together at different concentrations under batch anaerobic conditions to determine the optimal hydrogen producing potential and waste treatment of each. Cheese whey at a concentration of 55% was combined with dairy manure at a concentration of 45% to produce 1.53 liters of hydrogen per liter of substrate. These results are significant because the control, synthetic wastewater, which was a glucose-based substrate, produced less hydrogen, 1.34 liters per liter of substrate, than the mixture of cheese whey and dairy …
Student Achievement And Affective Traits In Electrical Engineering Laboratories Using Traditional And Computer-Based Instrumentation, Matthew D. Lammi
Student Achievement And Affective Traits In Electrical Engineering Laboratories Using Traditional And Computer-Based Instrumentation, Matthew D. Lammi
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Distance education has the ability to transcend distance and time, reaching students anywhere at any time, particularly those underrepresented in engineering. Engineering is a practice-oriented profession requiring an interweaving of scientific theory and applied hands-on activities. Despite the need for distance education in engineering, few studies have systematically investigated the impact of student achievement and attitude in distance engineering laboratories. This quasi-experimental research addressed that need by studying the cognitive and affective domains of achievement in engineering laboratories while employing computer-based and traditional oscilloscopes. The students from two courses, electrical engineering for nonmajors and electronic fundamentals, were randomly assigned into …
Decadal-Scale Changes On Coral Reefs In Quintana Roo, Mexico, Thaddeus Allen Nicholls
Decadal-Scale Changes On Coral Reefs In Quintana Roo, Mexico, Thaddeus Allen Nicholls
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In 1988 data on coral reef community composition were collected from two areas, Akumal and Chemuyil, Quintana Roo, Mexico, ranging from 5-35m depth. These areas were revisited in 2005 and data were collected by the same methods and at the same depths as in 1988. Data from 1988 and 2005 were compared to determine if the coral reefs had undergone significant changes, and what specific changes had occurred. Chi-square analysis determined that community composition data collected in 1988 are significantly different from data collected in 2005 at all sites and depths within the categories of corals, gorgonians, sponges, and macroalgae. …

The purpose of this study was to examine the socio-demographic and financial characteristics that were associated with the likelihood of a discharge among Chapter 12 bankruptcy filers in Utah, Idaho, and Wyoming. Previous bankruptcy studies conducted in Utah have looked at the same associations in Chapter 7 and Chapter 13. This study contains individual filer-level data from 158 Chapter 12 bankruptcy cases filed in Utah, Idaho, and Wyoming between 1997 and 2005. These cases were accessed through the Web-PACER system, a database of imaged court documents filed in district bankruptcy courts. Free access to this system was given by the …
Evaluation Of Arrayed-Field Concentration Measurements And U. S. Epa-Regulatory Models For The Determination Of Mixed-Source Particulate Matter Emissions, Derek Jones
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
With the continued population growth and the blurring of the urban and rural interface, air quality impacts associated with agricultural particle-producing processes are becoming increasingly important. There is a lack of emission rate data from these source types and no prescribed measurement technique available to the agricultural and regulatory communities. One technique that has shown promise is combining field measurements with inverse modeling. This approach was used herein to examine particulate emissions from an almond harvesting operation, a cotton ginning facility, and comparative emissions from conservation versus conventional tillage practices. EPAapproved models ISCST3 and AERMOD were used with AirMetrics samplers. …

In order to evaluate the short-term educational and behavioral impact of the American Heart Association's "Face the Fats" web application had upon college students, a study involving 116 Utah State University undergraduate students was conducted. A one-group pre-posttest design was utilized to answer eight research questions focusing on: health risks associated with trans fat, general trans fat knowledge, ability to identify foods containing trans and saturated fats, food label information, healthy alternatives to trans fat, and readiness to change trans fat intake. Participants completed an online pretest survey and then viewed the "Face the Fats" website at their own pace. …
Evolutionary Genetics Of Tetrodotoxin (Ttx) Resistance In Snakes: Tracking A Feeding Adaptation From Populations Through Clades, Chris R. Feldman
Evolutionary Genetics Of Tetrodotoxin (Ttx) Resistance In Snakes: Tracking A Feeding Adaptation From Populations Through Clades, Chris R. Feldman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Understanding the nature of adaptive evolution has been the recent focus of research detailing the genetic basis of adaptation and theoretical work describing the mechanics of adaptive evolution. Nevertheless, key questions regarding the process of adaptive evolution remain. Ultimately, a detailed description of the ecological context, evolutionary history, and genetic basis of adaptations is required to advance our understanding of adaptive evolution. To address some of the contemporary issues surrounding adaptive evolution, I examine phenotypic and genotypic changes in a snake feeding adaptation.
Adaptations can arise through fixation of novel mutations or recruitment of existing variation. Some populations of the …

Following chapters on the expected ionospheric conditions and an overview of Langmuir probe theory, a chapter addressing the difficulties involved with pico-satellite Langmuir probes is presented. Also, the necessary satellite-to-probe surface area requirements in order to achieve confidence in pico-satellite Langmuir probe data, for the orbital regions of interest to this thesis, are stated.
A Critical Analysis Of The Cooperatives Working Together Program, Spencer N. Parkinson
A Critical Analysis Of The Cooperatives Working Together Program, Spencer N. Parkinson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study analyzes the effectiveness of the Cooperatives Working Together (CWT) program. This program is believed to have improved the farm-level price of milk since it began in July 2003. To date, no publicly available analysis addressing this question has been conducted. Total milk removed by the program was determined and expressed as a percentage of total milk produced nationally during the same time frame. Elasticity measures from prior studies were adapted to determine the impact of the program. This analysis suggests the program has had a significantly positive effect on the price of milk. Issues dealing with future action …

Experiments In Distributed Multi-Robot Coordination, Larry Dale Ballard
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Consensus control algorithms for multi-agent systems are an area of much research. Several consensus control laws are experimentally validated on a multi-robot testbed in this thesis. A graphical user interface (GUI) is developed that simplies use of the testbed, as well as allows the execution of the testbed programs to be divided across multiple computers. This not only provides a more powerful computing environment, but a more realistic communication environment for the testbed. A method for a time varying or dynamic formation is both proposed and experimentally validated on the testbed. This research also explores a method for dynamic group …

Hydrological Characterization Of A Riparian Vegetation Zone Using High Resolution Multi-Spectral Airborne Imagery, Osama Zaki Akasheh
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Middle Rio Grande River (MRGR) is the main source of fresh water for the state of New Mexico. Located in an arid area with scarce local water resources, this has led to extensive diversions of river water to supply the high demand from municipalities and irrigated agricultural activities. The extensive water diversions over the last few decades have affected the composition of the native riparian vegetation by decreasing the area of cottonwood and coyote willow and increasing the spread of invasive species such as Tamarisk and Russian Olives, harmful to the river system, due to their high transpiration rates, …
