Lithofaces And Sequence Architecture Of The Upper Paradox Formation (Middle Pennsylvanian)In The Subsurface Northern Blanding Subbasin, Paradox Basin, Utah, Geoffrey William Ritter Apr 2018

Lithofaces And Sequence Architecture Of The Upper Paradox Formation (Middle Pennsylvanian)In The Subsurface Northern Blanding Subbasin, Paradox Basin, Utah, Geoffrey William Ritter

Theses and Dissertations

THE PARADOX Basin is a northwest-southeast trending intracratonic basin that formedin southwestern Colorado, southeastern Utah and adjacent parts of Arizona and New Mexicoduring the late Paleozoic Era. During rise of the adjacent Uncompahgre Uplift (Ancestral RockyMountains) the rapidly subsiding basin was filled with over 2000 m of Permo-Pennsylvaniansediments. Stacked depositional sequences accumulated in three roughly parallel facies belts: anortheastern clastic belt (adjacent to uplift), a central salt and black shale belt, and asouthwestern carbonate belt. Over 400 million barrels of oil have been extracted from upperParadox (Desert Creek and Ismay) carbonates in the southern Blanding Subbasin (Greater AnethField) since 1956. …


Development Of A Real-Time Auralization System For Assessment Of Vocal Effort In Virtual-Acoustic Environments, Jennifer Kay Whiting Apr 2018

Development Of A Real-Time Auralization System For Assessment Of Vocal Effort In Virtual-Acoustic Environments, Jennifer Kay Whiting

Theses and Dissertations

This thesis describes the development of the real-time convolution system (RTCS) for a little-studied talker/listener in virtual acoustic environments. We include descriptions of the high-resolution directivity measurements of human speech, the RTCS system components, the measurement and characterization of oral-binaural room impulse responses (OBRIRs) for a variety of acoustic environments, and the compensation filter necessary for its validity. In addition to incorporating the high-resolution directivity measurements, this RTCS improved on that developed by Cabrera et al. [1] through the derivation and inclusion of the compensation filter. Objective measures in the time- and frequency-domains, as well as subjective measures, were developed …


Effect Of Inclined Loading On Passive Force-Deflection Curves And Skew Adjustment Factors, Joshua Rex Curtis Apr 2018

Effect Of Inclined Loading On Passive Force-Deflection Curves And Skew Adjustment Factors, Joshua Rex Curtis

Theses and Dissertations

Skewed bridges have exhibited poorer performance during lateral earthquake loading in comparison to non-skewed bridges (Apirakvorapinit et al. 2012; Elnashai et al. 2010). Results from numerical modeling by Shamsabadi et al. (2006), small-scale laboratory tests by Rollins and Jessee (2012), and several large-scale tests performed by Rollins et al. at Brigham Young University (Franke 2013; Marsh 2013; Palmer 2013; Smith 2014; Frederickson 2015) led to the proposal of a reduction curve used to determine a passive force skew reduction factor depending on abutment skew angle (Shamsabadi and Rollins 2014). In all previous tests, a uniform longitudinal load has been applied …


Academic Persistence Among Native American High School Students, Tianna Jeanne Buckley Apr 2018

Academic Persistence Among Native American High School Students, Tianna Jeanne Buckley

Theses and Dissertations

Qualitative interviews with 12 Native American high school junior and senior students who grew up on reservations identified the following themes related to their persistence in college: (a) faculty support, (b) structured social support, (c) family support or the lack thereof, (d) motivation to be better, and (e) encountering racism. The results indicated a need for clear academic expectations between the school district and the tribal liaisons, multicultural training to foster positive relationships from the primary to secondary level, and structured college preparatory instruction designed for Native American students. Results also indicated a need for further research into the educational …


A Cognitive Approach To Predicting Academic Success In Computing, Colby Goettel Apr 2018

A Cognitive Approach To Predicting Academic Success In Computing, Colby Goettel

Theses and Dissertations

This research examines the possible correlations between a computing student's learning preference and their academic success, as well as their overall satisfaction with their major. CS and IT seniors at BYU were surveyed about their learning preferences and satisfaction with their major. The research found that IT students who are more reflective in their learning preference tend to have higher grades in their major. Additionally, it found that student age and their parents' education level were significant players in their academic success. However, there were no correlations found between major satisfaction and academic performance.


Performance Self-Appraisal Calibration Of Esl Students On A Proficiency Reading Test, Jodi Mikolajcik Petersen Apr 2018

Performance Self-Appraisal Calibration Of Esl Students On A Proficiency Reading Test, Jodi Mikolajcik Petersen

Theses and Dissertations

Self-assessment as a placement measure or accurate assessment of skill has been scrutinized in previous research. Findings have shown a general human tendency towards overconfidence in performance (Kruger & Dunning, 1999). This study looks at performance self-appraisals in an ESL population, with participants from varying cultural backgrounds. Performance self-appraisal calibration is a measure of the relationship between an examinee's perceived skill (or confidence) and their actual skill (or ability) on a given exam item (Phakiti, 2016). Being well-calibrated is an indication that test takers know their strengths and weaknesses and thus the difference between confidence and ability is minimal, whereas …


Thin Film Carbon Nanofuses For Permanent Data Storage, Kevin Robert Laughlin Apr 2018

Thin Film Carbon Nanofuses For Permanent Data Storage, Kevin Robert Laughlin

Theses and Dissertations

We have fabricated nanofuses from thin-film, arc-evaporation carbon for use in permanent data storage. Thin film carbon fuses have fewer fabrication barriers and retain the required resistivity and structural stability to work as a data storage medium. Carbon thin films were characterized for their electrical, microstructural, and chemical bonding properties. Annealing the thin-film carbon in an argon environment at 400°C reduced the resistivity from about 4*10-2 Ω cm as deposited down to about 5*10-4 Ω cm, allowing a lower blowing voltage. Nanofuses with widths ranging from 200 nm down to 60 nm were fabricated and tested. They blow …

Progress Toward Synthetically Simplified Natural Anticancer Peptide, David W. Kastner, Steven L. Castle Mar 2018

Progress Toward Synthetically Simplified Natural Anticancer Peptide, David W. Kastner, Steven L. Castle

Library/Life Sciences Undergraduate Poster Competition 2018

Yaku’amide A was isolated in late 2010 from the deep-sea sponge Ceratopsion sp. and exhibits potent inhibitory activity against 39 human cancer cell lines via a potentially novel mode of action. However, the total synthesis requires many steps and produces low yields. In this study, we determined two simpler YA analogues that may retain its anticancer properties and can be synthesized in larger quantities. The analogues replace dehydroisoleucine with either dehydroethylnorvaline or dehydrovaline.

14-3-3zeta Role In Promoting Survival Of Cells To Facilitate Progression Of Cancer, Katie Pennington, Eranga Roshan, Joshua Andersen, Katherine K. Mccormack

Student Works

The regulatory protein 14-3-3z promotes cellular growth and survival, and high expression levels of 14-3-3z are associated with mortality in multiple cancer types. 14-3-3z binds cellular proteins in a phosphorylation-dependent manner to modulate their functions. We have been characterizing the interactome of 14-3-3z which will likely lead to candidates for novel therapies for chemoresistant cancers. Tumor cells must be able to survive in a variety of stresses within the tumor microenvironment, including hypoxia, which occurs when tumors lack adequate blood supply. Previous data from our lab suggested that 14-3-3z promotes the adaptation of tumor cells to hypoxic stress. Our hypothesis …

A Large-Scale Analysis Of How Openssl Is Used In Open-Source Software, Scott Jared Heidbrink Mar 2018

A Large-Scale Analysis Of How Openssl Is Used In Open-Source Software, Scott Jared Heidbrink

Theses and Dissertations

As vulnerabilities become more common the security of applications are coming under increased scrutiny. In regards to Internet security, recent work discovers that many vulnerabilities are caused by TLS library misuse. This misuse is attributed to large and confusing APIs and developer misunderstanding of security generally. Due to these problems there is a desire for simplified TLS libraries and security handling. However, as of yet there is no analysis of how the existing APIs are used, beyond how incorrect usage motivates the need to replace them. We provide an analysis of contemporary usage of OpenSSL across 410 popular secure applications. …

Nonlinear Control Framework For Gimbal And Multirotor In Target Tracking, Jae Hun Lee Mar 2018

Nonlinear Control Framework For Gimbal And Multirotor In Target Tracking, Jae Hun Lee

Theses and Dissertations

This thesis presents some existing gimbal and UAV control algorithms as well as novel algorithms developed as the extensions of the existing ones. The existing image-based visual servoing algorithms for both gimbal and UAV require the depth information to the object of interest. The depth information is not measurable when only a monocular camera is used for tracking. This thesis is the result of contemplation to the question: how can the necessity for a depth measurement be removed? A novel gimbal algorithm using adaptive control is developed and presented with simulation and hardware results. Although the estimated depth using the …

Lithofacies And Sequence Architecture Of The Upper Desert Creek Sequence (Middle Pennsylvanian, Paradox Formation) In The Greater Aneth Field, Southern Paradox Basin, Utah, Evan R. Gunnell

Theses and Dissertations

The Greater Aneth Buildup (GAB) is comprised of the 3rd-order middle Pennsylvanian (Desmoinesian) Desert Creek sequence of the Paradox Formation. A hierarchy of 4th- and 5th order, carbonate-dominated cycles comprise the Upper Desert Creek (UDC) 4th-order sequence. A SE to NW trending transect line, utilizing core and petrophysical data from six oil and gas wells (from SE to NW wells R-19, Q-16, O-16, J-15, K-430, E-313), revealed deposition of seven carbonate facies within four 5th-order parasequences in the UDC. While each of the seven carbonate facies are present across the transect line, the UDC parasequences are dominated by a shallow-water …

Waveguide-Based Spatial Light Modulators For Use In Holographic Video Displays, Kamran Qaderi Mar 2018

Waveguide-Based Spatial Light Modulators For Use In Holographic Video Displays, Kamran Qaderi

Theses and Dissertations

Film display holograms typically diffract light over a wide enough view-angle to be viewed, directly, without intervening optics. However, all holographic video displays must use optics beyond the hologram surface to overcome the challenges of small display extent and low diffraction angle by using some form of demagnification and derotation. We report a leaky mode waveg- uide spatial light modulator (SLM) with sufficiently high angular diffraction to obviate the need for demagnification in scanned aperture systems. This was achieved by performing a number of experiments to determine the depth of the annealed, proton-exchanged waveguide which corresponded to a maximized diffracted …


Paleo-Environmental Interpretations And Weathering Effects Of The Mowry Shale From Geochemical Analysis Of Outcrop Samples In The Western Margin Of The Wind River Basin Near Lander, Wyoming, Trevor Robinson Tuttle Mar 2018

Paleo-Environmental Interpretations And Weathering Effects Of The Mowry Shale From Geochemical Analysis Of Outcrop Samples In The Western Margin Of The Wind River Basin Near Lander, Wyoming, Trevor Robinson Tuttle

Theses and Dissertations

The Cretaceous Mowry Shale is an organic-rich, siliceous marine shale, and as such is a known source rock in the Western United States. Studies have documented that total organic carbon (TOC) in the Wind River Basin, Wyoming increases to the southeast. These studies cover large areas with limited sample sets. In this study, over 250 samples were collected near Lander, Wyoming to address spatial heterogeneity of TOC within the Mowry Shale at a much finer scale than previously examined. Samples were collected along five vertical sections at three localities, and following correlation of the vertical sections, which was strongly aided …


Discovery Of Possible Paleotsunami Deposits In Pangandaran And Adipala, Java, Indonesia Using Grain Size, Xrd, And 14C Analyses, Kevin L. Stuart Mar 2018

Discovery Of Possible Paleotsunami Deposits In Pangandaran And Adipala, Java, Indonesia Using Grain Size, Xrd, And 14C Analyses, Kevin L. Stuart

Theses and Dissertations

Grain size, 14C age, and X-ray diffraction (XRD) analyses of sediments indicate possible tsunami deposits on the southern coast of Java near Pangandaran and Adipala. Previous studies that have described known recent and paleotsunami deposits were used for comparison. Fining-upward grain size trends, interbedded sand and mud, sediment composition, and trends in heavy mineral abundances are among the characteristics used for tsunami deposit identification. At Batu Kalde, an archaeological site south of Pangandaran, a layer of aragonitic sand with marine fossils was found atop a layer of archaeological fragments at an elevation of ~2-5 m. It is likely this …


Rotational Stiffness Models For Shallow Embedded Column-To-Footing Connections, Ashley Lauren Sadler Mar 2018

Rotational Stiffness Models For Shallow Embedded Column-To-Footing Connections, Ashley Lauren Sadler

Theses and Dissertations

Shallow embedded steel column connections are widely used in steel buildings; however, there is insufficient research about this connection type to understand the actual rotational stiffness that the connection provides. Shallow embedded steel columns are when a steel column is anchored to the foundation slab and then unreinforced concrete is poured around the base plate and the base of the column. This thesis seeks to further quantify the rotational stiffness available in this type of connection due to the added concrete and improve an existing model in order to represent the rotational stiffness. Existing data from two series of experiments …


Effects Of Competition In Violent And Nonviolent Video Games On Aggressive/Prosocial Behavior, Christopher Edward Hawk Mar 2018

Effects Of Competition In Violent And Nonviolent Video Games On Aggressive/Prosocial Behavior, Christopher Edward Hawk

Theses and Dissertations

Previous research shows that playing violent video games leads to increases in aggressive feelings, thoughts, and behaviors. However, recent research has questioned the reliability of these findings. Two important variables associated with aggressive outcomes that have yet to be fully explored in the violent video game literature are the competitive aspects of the games and the outcomes of that competition (e.g., winning or losing). The present study was a two (gameplay: violent vs. nonviolent) by two (difficulty: easy vs. hard) by three (competition: no competition vs. competition win vs. competition lose) between-subjects factorial design, with aggressive/prosocial behavior measured as the …


Total Hemispherical Apparent Radiative Properties Of The Infinite V-Groove With Specular Reflection, Rydge B. Mulford, Nathan S. Collins, Michael S. Farnsworth, Matthew R. Jones, Brian D. Iverson Mar 2018

Total Hemispherical Apparent Radiative Properties Of The Infinite V-Groove With Specular Reflection, Rydge B. Mulford, Nathan S. Collins, Michael S. Farnsworth, Matthew R. Jones, Brian D. Iverson

Faculty Publications

Multiple reflections in a cavity geometry augment the emission and absorption of the cavity opening relative to a flat surface in a phenomenon known as the cavity effect. The extent of the cavity effect is quantified using apparent absorptivity and apparent emissivity. Analysis of complicated thermal systems is simplified through application of apparent radiative properities to cavity geometries. The apparent radiative properties of a specularly-reflecting, gray, isothermal V-groove have been derived analytically, but these results have not been validated experimentally or numerically. Additionally, the model for apparent absorptivity of an infinite V-groove subjected to partial illumination in the presence of …


Chlorophyll Dynamics Around The Southern Channel Islands, Craig Gelpi Feb 2018

Chlorophyll Dynamics Around The Southern Channel Islands, Craig Gelpi

Western North American Naturalist

We determine spatial and temporal dynamics of chlorophyll for the Southern California Bight through analysis of 10 years of chlorophyll product derived from the Moderate Resolution Imaging Spectroradiometer on the Earth Observing System satellite Aqua (MODIS-AQUA). Concentrating on the Southern Channel Islands, we find an island mass effect associated with San Nicolas; that is, some chlorophyll originates near the island. This signal is most evident during the fall after the typical spring phytoplankton bloom subsides. In contrast, there is a relative dearth of chlorophyll around Santa Catalina Island, and its seasonal modulation corresponds to the spring bloom, implying that the …


Atonement In The Book Of Mormon And In The New Testament, Noel B. Reynolds Feb 2018

Atonement In The Book Of Mormon And In The New Testament, Noel B. Reynolds

Faculty Publications

New Testament writers consistently and vigorously testify that Jesus Christ has atoned for the sins of all mankind and has provided for their resurrection from the dead. In so doing they point to historical facts, the things he did to accomplish this—to his sufferings in Gethsemane and to his crucifixion and resurrection. Some of these writers also offer explanations or characterizations of that atonement intended to illuminate how it was possible or how it works. The various explanations offered are not identical or even always consistent with each other as they vary somewhat between writers, or sometimes even within the …


In Situ Uv-Visible Assessment Of Iron-Based High-Temperature Water-Gas Shift Catalysts Promoted With Lanthana: An Extent Of Reduction Study, Basseem B. Hallac, Jared C. Brown, Eli Stavitski, Roger G. Harrison, Morris D. Argyle Feb 2018

In Situ Uv-Visible Assessment Of Iron-Based High-Temperature Water-Gas Shift Catalysts Promoted With Lanthana: An Extent Of Reduction Study, Basseem B. Hallac, Jared C. Brown, Eli Stavitski, Roger G. Harrison, Morris D. Argyle

Faculty Publications

The extent of reduction of unsupported iron-based high-temperature water-gas shift catalysts with small (< 5 wt %) lanthana contents was studied using UV-visible spectroscopy. Temperature- programmed reduction measurements showed that lanthana content higher than 0.5 wt % increased the extent of reduction to metallic Fe, while 0.5 wt % of lanthana facilitated the reduction to Fe3O4. In situ measurements on the iron oxide catalysts using mass and UV-visible spectroscopies permitted the quantification of the extent of reduction under temperature-programmed reduction and high-temperature water-gas shift conditions. The oxidation states were successfully calibrated against normalized absorbance spectra of visible light using the Kubelka-Munk theory. The normalized absorbance relative to the fully oxidized Fe2O3 increased as the extent of reduction increased. XANES suggested that the average bulk iron oxidation state during the water-gas shift reaction was Fe+2.57 …


Open Hydrology Courseware Using The United States Geological Survey’S National Water Census Data Portal, Jake Nelson, Daniel P. Ames, David Blodgett Feb 2018

Open Hydrology Courseware Using The United States Geological Survey’S National Water Census Data Portal, Jake Nelson, Daniel P. Ames, David Blodgett

Open Water Journal

The U.S. Geological Survey (USGS) is the primary U.S. Government agency for water data collection and dissemination. In this role, the USGS has recently created and deployed a National Water Census Data Portal (NWC-DP) which provides access to streamflow, evapotransporation, precipitation, aquatic biology and other data at the national level. Recognizing the value of these data sets for hydrologic science education, this paper presents an effort to bridge the gap between pencil–and-paper-based hydrology curriculum and the USGS NWC-DP resource. Specifically, we have developed an R package, National Water Census Education (NWCEd), and five associated laboratory exercises that integrate R- and …
