Linkage of Climate Diagnostics in Predictions for Crop Production: Cold Impacts in Taiwan and Thailand

Parichart Promchote
This research presents three case studies of low temperature anomalies that occurred during the winter–spring seasons and their influence on extreme events and crop production. We investigate causes and effects of each climate event and developed prediction methods for crops based on the climate diagnostic information. The first study diagnosed the driven environmental-factors, including climate pattern, climate change, soils moisture, and sea level height, associated with the 2011 great flood in Thailand and resulting total...

Spectral, Energy and Computation Efficiency in Future 5G Wireless Networks

Haijian Sun
Wireless technology has revolutionized the way people communicate. From first generation, or 1G, in the 1980s to current, largely deployed 4G in the 2010s, we have witnessed not only a technological leap, but also the reformation of associated applications. It is expected that 5G will become commercially available in 2020. 5G is driven by ever-increasing demands for high mobile traffic, low transmission delay, and massive numbers of connected devices. Today, with the popularity of smart...

Feature Selection and Analysis for Standard Machine Learning Classification of Audio Beehive Samples

Chelsi Gupta
The beekeepers need to inspect their hives regularly in order to protect them from various stressors. Manual inspection of hives require a lot of time and effort. Hence, many researchers have started using electronic beehive monitoring (EBM) systems to collect critical information from beehives, so as to alert the beekeepers of possible threats to the hive. EBM collects information by applying multiple sensors into the hive. The sensors collect information in the form of video,...

Social Media Use During Crisis Events: A Mixed-Method Analysis of Information Sources and Their Trustworthiness

Apoorva Chauhan
This dissertation consists of three studies that examine online communications during crisis events. The first study identified and examined the information sources that provided official information online during the 2014 Carlton Complex Wildfire. Specifically, after the wildfire, a set of webpages and social media accounts were discovered that were named after the wildfire—called Crisis Named Resources (or CNRs). CNRs shared the highest percentage of wildfire-relevant information. Because CNRs are named after a crisis event, they...

Investigation of Graphene Interconnections for Multifunctional Reconfigurable Antenna Beam Steering

Joshua R. Perkins
In high frequency, high-performance wireless communications, direct line of sight antennas are common. The issue with the line of sight antennas is the need to redirect the physical antenna to achieve the best possible reception. Classical redirections are done by mechanical movements: hand tuning and motors. Our multi-functional re-configurable antenna (MRA) concept allows for electrical and non-mechanical antenna reorientation. This work investigates two important concepts in the development and enhancement of future MRA devices: special,...

Use of Landsat Imagery and Geographical Information Systems in the Assessment of Rangeland Cover and Wildlife Habitat

Mary Hunnicutt
The first chapter of this thesis reviews applications of satellite remote sensing and geographical information systems (GIS) in wildlife studies. The simpler uses of remote sensing are for habitat mapping, often using satellite imagery classified for other natural resources. More sophisticated applications incorporate remotely sensed data into a GIS for the digital manipulation of data planes. The most advanced applications are those which use remote sensing and GIS in models predicting habitat quality or population...

The History of Cokeville, Wyoming

Errol Jack Lloyd
Cokeville, Wyoming, is situated at the confluence of the Bear River and Smiths Fork valleys in southwestern Wyoming. Settled in 1874, the Cokeville area has experienced much the same political, economic, and social developments typical of other small rural towns in the western United States; but it is unlike neighboring settlements in that it was not dominated by the Church of Jesus Christ of Latter-day Saints during its early growth. Depending upon an agricultural economic...

Growth and Water Relations of Native Wheatgrass Populations

Brian P. Bell
Screening populations for development into released plant materials can be done inexpensively and in a timely manner. A common approach has been to quantify the amount of shoot dry mass produced as a surrogate for competitiveness. Besides dry mass production , other morphological characteristics have been employed , but physiological parameters have received less emphasis. Dry mass production may be an important characteristic, but identifying the traits responsible can be just as imperative . Populations...

Investigation of the Molecular Determinants and Extrinsic Factors that Regulate PRMT Product Specificity

Tamar B. Cáceres
Protein arginine methylation is an important modification of proteins, involved in many cellular processes. Some examples are transcription, RNA editing, cellular communication, DNA repair, viral replication and chromatin remodeling. In recent years, the significance of protein arginine methyltransferases (PRMTs) in human diseases has been increasingly studied, especially in cardiovascular disease and cancer. Although the importance of these enzymes is recognized, the understanding of how exactly PRMTs function is still limited. Very little information is available...

Query AutoAwesome

Chetna Suryavanshi
This research investigates how to improve legacy queries. Legacy queries are queries that programmers have coded and are used in applications. A database application typically has tens to hundreds of such queries. One way to improve legacy queries is to add new, interesting queries that are similar to or based on the set of queries. We propose Query AutoAwesome, a tool to generate new queries from legacy queries. The Query AutoAwesome philosophy is taken from...

Optimization of Biogas Production by Use of a Microbially Enhanced Inoculum

Anna Doloman
A renewable energy source, biogas, comprises of methane (80%) and carbon dioxide (15%), and is a great alternative to the conventional fossil-based fuels, such as coal, gas and oil. Biogas is created during anaerobic biological digestion of waste materials, such as landfill material, animal manure, wastewater, algal biomass, industrial organic waste etc. A biogas potential from organic waste in the United States is estimated at about 9 million tons per year and technology allows capture...

The second component of this thesis will consist of the first four chapters of my memoir, with the remaining chapters to be completed post-graduation. These chapters take place the years before my parents’ deportation...

Isentropic Efficiency and Theoretical Analysis of the Planetary Rotor Expander

Joseph L. James
Expanders allow pressurized fluids to undergo a pressure decrease in a controlled environment via volumetric growth to extract fluid energy. There are many types of expanders, and the objective of this thesis is to model the efficiencies of the planetary rotor expander (PRE), a century-old design undeveloped due to insufficient manufacturing capabilities (until recently). Geometric relationships are derived and mathematical models are generated to determine the efficiency of the PRE as a function of design...

The Brigham City Co-Op: Case Study of an Efficient Economic and Social Institution

Stephen J. Valentine
The leaders of the Church of Jesus Christ of Latter-day Saints raced a twin dilemma in the years between 1868 to 1874. The specter of non-Mormon infiltration of society and destruction of the Mormon empire loomed menacingly on the horizon, and internal divisions and inequities threatened to destroy the religious ideals of unity and equality fostered by Mormons since the time of Joseph Smith, Jr. This twin crisis led Mormon leaders to institute church-wide economic...

Environmental Mediation: An Assessment and Case Study of the Logan Canyon Highway Controversy

Jared Glenn Parkinson
For a little more than twenty years, alternative methods of dispute management have been employed to address various environmental conflicts in order to avoid the more traditional method of litigation. Mediation is a voluntary process which involves face-to-face negotiation among parties and the use of a neutral third-party negotiator. Environmental mediation has helped manage disputes related to land use, natural resource management, use of public lands, water resources, energy development, air quality and toxins (Bingham...

MOSFET Audio Amplifier

Jeff Argast
My senior project is an audio amplifier utilizing MOSFETs as the output transistors to drive the speaker. Within this document I cover the details of designing an amplifier, and the methods used to build it. The most important part of the project is the output stage. In this section I chose MOSFETs over BJTs. Several advantages ensued from this decision, resulting in a simple design. Further, the transformer must be able to supply the necessary...

Facilitating Acceptance of Alternative Communication Devices in Classrooms by Teachers

Tracie Empey
There exists a number of persons who lack adequate speech for communicative purposes. Many of the non-vocal children and adults from these populations have benefited from the development of various alternative communication devices. The non-vocal individual is one whose speech does not provide a functional means of meeting communication needs. However, this does not necessarily mean that the non-vocal individual has no speech or vocalization at all, nor does it mean that the individual may...

Parent-Child Privileges

Angela Furca
This paper will demonstrate the desirability and necessity of recognizing the parent-child testimonial privilege. As this is a legal research paper, it will present arguments for both sides of the issue, while proving that the parent-child testimonial privilege deserves recognition and is fundamental in maintaining healthy family relationships.

Who's More Cruel, Johnny or Jenny? Sex Differences in Adults' Perceptions of Cruelty to Animals by Children

Teresa Michelle Thompson
As a symptom of Conduct Disorder, cruelty to animals (DSM IV, 1994) is often assessed via parental checklists (e.g., Child Behavior Checklist). However, little information exists on the criteria that adults use to make judgments of cruelty.

Mink Research: Wet Vs. Wet/Pellet Feeding Programs

Troy W. Hobbs
Hobbs Fur Farm, of Franklin, Idaho, has been feeding the Fur-Pro pellet (made by Fur Breeders CO-OP, Midvale, Utah) for the past 8 years. Tim Hobbs, the owner, questioned the efficacy of the pellet feed. His concern was the quality of pelt being produced by mink on the wet/pellet feed program. A comparison of mink raised on the wet/pellet feed program vs. mink raised solely on a wet feed program was performed to determine if...

Japan's Manchukuo Economic Development or Militaristic Seizure

Nathan Douglas Alder
Was the founding of the State of Manchukuo an act of independence brought about by the people of Manchuria or a planned take-over by the Japanese military and government? Was Manchukuo a favored trading nation of Japan or just another province in an expanding Japanese empire? Answers to these questions are the motivation for this paper, and aim at the heart of Manchukuo's history.

A Universal Mechanism for N2 Binding to and Differing Reactivity of the E4(4H) State of Mo-, V-, and Fe-Nitrogenases

Derek Franklin Harris
As a basic building block in many biological molecules, the element nitrogen (N) is essential for life. Dinitrogen (N2) is abundant in Earth’s atmosphere, but this form is biologically unavailable. To be biologically available, N2 must undergo a reduction reaction to the fixed form, ammonia (NH3). The industrial Haber-Bosch process, which accounts for approximately 50% of the worlds fixed nitrogen, uses energy from fossil fuels to achieve high pressures and temperatures to catalyze the reaction....
