Improved Endmember Mixing Analysis (Emma): Application To A Nested Catchment, Provo River, Northern Utah, Alyssa Nicole Thompson Aug 2023

Improved Endmember Mixing Analysis (Emma): Application To A Nested Catchment, Provo River, Northern Utah, Alyssa Nicole Thompson

Theses and Dissertations

An endmember mixing analysis (EMMA) is a hydrograph separation technique used to identify and quantify stream source contributions, but the error within the results of the analysis itself can be difficult to quantify. Employing EMMA to accurately quantify these contributions is particularly important for critical watersheds that supply water to large populations, such as montane watersheds. We applied EMMA to the Provo River, a nested catchment with three monitoring locations in northern Utah, to understand the limitations and potential improvements that could be made to EMMA. Four main endmembers (quartzite groundwater, soil water, snow and carbonate groundwater) were identified for …

Preliminary Reports

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

Robert F. Smith, "It Came to Pass' in the Bible and Book of Mormon." Manuscript, 1980. Pointing out that computer analysis will be necessary to make his observations conclusive, the author shows that the Book of Mormon, though less than a third the length of the King James Bible, contains more than twice as many recurrences of "came/come to pass." Furthermore, extensive cataloguing shows that all but three of the twenty books containing that phrase in the Bible are in the Old Testament. Another interesting characteristic: the phrase usually occurs in prose narrative, in both volumes of scripture. He explains …

Hebraic Elements In The Language Of The Book Of Mormon, Royal Skousen Aug 2023

Hebraic Elements In The Language Of The Book Of Mormon, Royal Skousen

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

Recent research has yielded another interesting clue about the language of the Nephites and about the manner in which it was translated into English. By comparing the original manuscript of the Book of Mormon to the subsequent printed versions, Royal Skousen has found that the original English-language text of the Book of Mormon contained expressions that are uncharacteristic of English. One such expression is a Hebrew-like conditional clause.

Real-Time Spatial Interference Removal And Maximum Ratio Combining In Communication Systems, Adam Gary Whipple Aug 2023

Real-Time Spatial Interference Removal And Maximum Ratio Combining In Communication Systems, Adam Gary Whipple

Theses and Dissertations

Radio frequency interference (RFI) is undesired and commonplace. Using a subspace projection method to spatially remove the interference from a phased array system gives results of a 30 dB interference null rejection (INR). Unmanned systems have been developed to observe underwater activity and communicate their observations to passing aircraft. These systems are currently limited by their use of a single transmitter. The uplink can be improved by using a dual-antenna beam steering approach to maximize the signal-to-noise ratio (SNR) the aircraft receives. This approach demonstrates an increase in SNR of 3 dB when compared to a single transmitter.

The Unique Professional Journey Of Female High School Principals In Utah, Deon G. Leavy Aug 2023

The Unique Professional Journey Of Female High School Principals In Utah, Deon G. Leavy

Theses and Dissertations

Women in the United States are underrepresented in high school principalships. A review of literature identified specific barriers that have historically contributed to this disparity including role congruity, normative male dominance, and gender bias against women. Furthermore, the high school principalship has been defined over time from a male perspective assumed to be the universal reality leaving the unique career experiences of female high school principals glossed over and often misunderstood. Similar barriers most likely have also contributed to the underrepresentation of female high school principals in Utah, yet intentional studies analyzing their unique career journeys have not been completed. …

Continuous-Time Trajectory Estimation And Its Application To Sensor Calibration And Differentially Flat Systems, Jacob C. Johnson Aug 2023

Continuous-Time Trajectory Estimation And Its Application To Sensor Calibration And Differentially Flat Systems, Jacob C. Johnson

Theses and Dissertations

State estimation is an essential part of any robotic autonomy solution. Continuous-time trajectory estimation is an attractive method because continuous trajectories can be queried at any time, allowing for fusion of multiple asynchronous, high-frequency measurement sources. This dissertation investigates various continuous-time estimation algorithms and their application to a handful of mobile robot autonomy and sensor calibration problems. In particular, we begin by analyzing and comparing two prominent continuous-time trajectory representations from the literature: Gaussian processes and splines, both on vector spaces and Lie groups. Our comparisons show that the two methods give comparable results so long as the same measurements …

Examining The Validity Of A Dynamic Assessment Of Narrative Language To Identify Language Disorder In Diverse School-Age Children, Samantha Kate Rainsdon Meek Aug 2023

Examining The Validity Of A Dynamic Assessment Of Narrative Language To Identify Language Disorder In Diverse School-Age Children, Samantha Kate Rainsdon Meek

Theses and Dissertations

The United States is a culturally and linguistically diverse country. Few assessments used in educational settings have been developed that can be used appropriately with culturally and linguistically diverse students, and research has shown that static, norm-referenced assessments are often biased against these students. One alternative method that shows great promise for overcoming the limitations of static, norm-referenced tests is dynamic assessment. Despite the research and recommendations that support the use of dynamic assessments, relatively few dynamic assessments have been formally developed for the purpose of identifying language disorder. Therefore, the current study sought to determine the validity of a …

Potential Clean-Label Astringency Maskers For Acidic Whey Protein Beverages, Jozxelle Tongson Gao Aug 2023

Potential Clean-Label Astringency Maskers For Acidic Whey Protein Beverages, Jozxelle Tongson Gao

Theses and Dissertations

Whey Protein Ready-to-Drink (RTD) beverages are popular nutritional products due to their high protein content, complete amino acid profile, convenience, and flavor. However, astringency imparted by whey protein at low pH (pH <4.5) can significantly reduce consumer liking. Astringency is a complex problem, so it may require a multi-faceted solution. Samples were created through Response Surface Methodology (RSM), utilizing parameters determined through literature review and preliminary testing. There is evidence that sucrose may help to reduce astringency in wine. Various natural sweeteners like stevia, monk fruit extract, and sweet proteins: thaumatin and brazzein were evaluated to observe if they may reduce the astringency in acidic whey protein RTD beverages. Samples were assessed by trained quantitative descriptive analysis (QDA), consumer acceptance, and focus group panels. Formulas were instrumentally measured for pH, brix, zeta potential, and particle size. pH and brix were useful measures for monitoring processing consistency, but neither related to level of astringency of samples. Zeta potential instrumental data coincided with results of previous studies finding that a decrease in zeta potential within the range of pH 3-5 correlated with less astringency with whey protein isolates. Particle size relation to astringency is dependent on the zeta potential. A large particle size measurement does not lead to higher astringency if the molecules do not interact due to electrostatic repulsion. Analytical measurements of the samples were statistically compared for differences that may relate to less astringent beverages. The QDA panel determined the combination of 0.20% thaumatin and 0.22% stevia rebaudioside M to most reduce astringency, however this did not correlate with higher acceptability as its acceptability remained as a neither like nor dislike rating. Consumers evaluated thaumatin, brazzein, and monk fruit to be clean-label ingredients after learning about their natural sources and flavor functionalities. More research about thaumatin, monk fruit, and especially brazzein is needed to find the ideal usage levels in AWB formulation. Brazzein was least preferred according to the focus group panel, who felt it did not reduce astringency. Future research could evaluate whether a higher concentration would be more effective. These findings aim to help sensorially improve acidic whey protein beverage formulations and provide the dairy beverage industry insight on creating and marketing more clean-label products.

Experimental Characterization Of Internal Wave Generation By Multiple Ridge Topographies, Natasha J. Wilson Aug 2023

Experimental Characterization Of Internal Wave Generation By Multiple Ridge Topographies, Natasha J. Wilson

Theses and Dissertations

Internal waves are three dimensional waves that occur in stratified fluids, where density increases with depth, such as the ocean and atmosphere. In the oceans, internal waves are continuously generated by tidal flow over subsea topography. The size and shape of the topography, as well as the stratification relative to the oscillation frequency influence the characteristics of the generated internal wave field. To advance the current understanding of how ridges on a subcritical topography changes the internal waves generated, four symmetric topographies are used with ridge numbers ranging from three to six. An additional single ridge topography is used, as …
