Post-Installed Fiber Optic Pressure Sensors On Subsea Production Risers For Severe Slugging Control, Ammon Eaton, Seyed M. Safdarnejad, John Hedengren, Kristi Moffat, Casey Hubbell, David Brower, Alexis Brower Jun 2015

Post-Installed Fiber Optic Pressure Sensors On Subsea Production Risers For Severe Slugging Control, Ammon Eaton, Seyed M. Safdarnejad, John Hedengren, Kristi Moffat, Casey Hubbell, David Brower, Alexis Brower

Faculty Publications

Fiber optic sensors have gained increasing use in monitoring offshore structures. The sensors have successfully monitored flowlines, umbilicals, wells, Tension Leg Platform (TLP) tendons, production and drilling risers, and mooring lines. Fiber optic sensors are capable of monitoring strain, temperature, pressure, and vibration. While the success of fiber optic monitoring has been clearly demonstrated, the sensors are now under consideration for automation applications. This paper details the plausibility of using pressure measurements from post-installed fiber Bragg grating (FBG) sensors with Model Predictive Control (MPC) to suppress severe slugging in subsea risers. Prior control schemes demonstrate that slugging is mitigated using …


Tolerance Values And Effects Of Selected Environmental Determinants On Diatom Distribution In Northwest And North Central Washington, Usa, Dean W. Blinn May 2015

Tolerance Values And Effects Of Selected Environmental Determinants On Diatom Distribution In Northwest And North Central Washington, Usa, Dean W. Blinn

Western North American Naturalist

Diatoms were collected at 165 stream, river, wall seep, and pond/lake sites in 9 counties in northwest and north central Washington, including the Olympic Pennsisula, over a 5-year period. Four hundred and fifteen species in 77 genera were identified. Species assemblages were compared to altitude, physicochemical factors, aquatic habitats, and land use on west and east sides of the North Cascade Range. Species richness averaged 30.5 per site on the west side and 43 on the east side. Diatom species richness showed significant positive correlations to total nitrogen, total phosphorus, pH, specific conductance, channel embeddedness, and water temperature, and a …


Lymphoblastoid Cell Line Generation From Sle Patient Lymphocytes, Vera Mayhew, Brian Poole May 2015

Lymphoblastoid Cell Line Generation From Sle Patient Lymphocytes, Vera Mayhew, Brian Poole

Journal of Undergraduate Research

Epstein-Barr Virus (EBV) is one of the viruses found most frequently in the human population. Approximately 95% of the population is infected in the United Sates by the age of 40. When primary infection occurs is young adulthood approximately 50% of cases result in infectious mononucleosis. Whether EBV infection results in mononucleosis manifestations or not, the virus stays latent in the infected individual’s B cells for the rest of their life.


How Yersinia Pseudotuberculosis Biofilm Formation Is Regulated By Global Regulator Csra, Jeffrey Schachterle, David Erickson May 2015

How Yersinia Pseudotuberculosis Biofilm Formation Is Regulated By Global Regulator Csra, Jeffrey Schachterle, David Erickson

Journal of Undergraduate Research

The bacteria Yersinia pestis is the causative agent of bubonic plague, and its ability to form biofilm in fleas is essential for plague transmission by fleas [1]. Y. pestis recently evolved from Y. pseudotuberculosis (Y. pstb), and the two have nearly identical genomes. Y. pestis forms a biofilm in fleas that is capable of blocking the flea’s feeding. These biofilms are made up of a community of bacteria adhering to a polysaccharide matrix that is made by the hmsHFRS gene products. Y. pstb is capable of infecting fleas, but will not block the flea’s feeding [1]. Since the …


Specialty Selection In The Face Of An Aging Demographic In Taiwan, Ian Christensen, Michael Barnes May 2015

Specialty Selection In The Face Of An Aging Demographic In Taiwan, Ian Christensen, Michael Barnes

Journal of Undergraduate Research

As of the end of August, 2013, senior citizens accounted for 11 percent of Taiwan’s population1. According to a report published by Taiwan’s Ministry of the Interior earlier this year, Taiwan’s population is predicted to be “hyper-aged”,with 20% of the population 65 or over, by 2025. With the world’s lowest birth rate (less than 0.9 children per woman)2 and a universal health care system, the aging of Taiwan’s population constitutes a massive challenge for the Taiwan health care system. Such a challenge is not, however, unique to Taiwan. Many populations, especially in developed nations such as those …


The Angel In The Theatre: Ellen Terry And Olga Nethersole As Liminal Victorian Performers, Anna Kristine Daines Rennaker May 2015

The Angel In The Theatre: Ellen Terry And Olga Nethersole As Liminal Victorian Performers, Anna Kristine Daines Rennaker

Theses and Dissertations

The late nineteenth century British stage was hopelessly confused. It couldn’t decide whether it was London’s principle source of entertainment—mainstream and respectable enoughfor Queen Victoria herself to patronize—or the seedbed of all corruption and deviance in Victorian society. At the center of this split identity was the actress, a figure both well-beloved (in the case of stars like Ellen Terry) and the literal embodiment of everything a Victorian women shouldn’t be—loose, sexualized, and working (in the case of her contemporary, Olga Nethersole). Because of this liminal position, Victorian actresses thus create a fascinatingmicrocosm in which to study the implications of …


Ligament Model Fidelity In Finite Element Analysis Of The Human Lumbar Spine, Mitchell Scott Hortin May 2015

Ligament Model Fidelity In Finite Element Analysis Of The Human Lumbar Spine, Mitchell Scott Hortin

Theses and Dissertations

The purpose of this project is to quantify the effects of increasing spinal ligament fidelity on the mechanics of the human lumbar spine using finite element analysis (FEA). In support of this goal, a material characterization study was completed to provide anisotropic, nonlinear material parameters for the human anterior longitudinal ligament. (ALL). Cadaveric samples of the human ALL were tested using a punch test technique. Multi- axial force-deformation data were gathered and fit to a commonly used transversely isotropic material model using an FEA system identification routine. The resulting material parameters produced a curve that correlated well with the experimental …


A Multidimensional Policy Evaluation Of The Utah Statewide Online Education Program, Royd Lyman Darrington May 2015

A Multidimensional Policy Evaluation Of The Utah Statewide Online Education Program, Royd Lyman Darrington

Theses and Dissertations

The focus of this research is in the area of online learning policy. Online learning is rapidly gaining popularity and is becoming more and more an integral part of the K–12 education landscape. Such a study is important because there are very few policies that have been created to govern online learning differently than traditional brick-and-mortar classrooms. Utah’s Statewide Online Education Program (SOEP) has been largely marketed as policy that does transcend these barriers. This research uses a multidimensional mixed-method case study to evaluate the program. The findings from this research provide evidence that the SOEP falls short of providing …


Stressed Syllables In Argentine Spanish In Queens, Nyc: Lengthening And F0 Early Peak Alignment, Giselle Gimenez Meiling May 2015

Stressed Syllables In Argentine Spanish In Queens, Nyc: Lengthening And F0 Early Peak Alignment, Giselle Gimenez Meiling

Theses and Dissertations

This thesis investigates the intonation of Argentine Spanish in Queens, NYC, with the goal of verifying if the unique prosody of producing early peak alignments in the F0 of Argentine Spanish, specifically of Porteños (those from Buenos Aires), is maintained among the intense contact influences with other varieties of Spanish in the area. Previous studies have reported this early peak alignment phenomenon in the Spanish spoken in Buenos Aires, and this paper strives to see if this still occurs among Argentine Spanish speakers in New York City. The Buenos Aires speakers were compared with other native Argentine Spanish speakers in …


Tree Islands Of Fertility Structure Bacterial Community Assembly And Functional Genes Contributing To Ecosystem Processes, Tayte Paul Campbell May 2015

Tree Islands Of Fertility Structure Bacterial Community Assembly And Functional Genes Contributing To Ecosystem Processes, Tayte Paul Campbell

Theses and Dissertations

In arid and semi-arid ecosystems, dominant tree species create dramatic mosaics of plant islands of fertility and relatively barren plant interspaces that exert immense pressure on ecosystem processes and offers an ideal opportunity to explore the impact of bacterial communities. We evaluated potential links between soil respiration and N mineralization, and community co-occurrence networks and predicted gene function across three tree island microsites (i.e., beneath tree canopies, at the canopy edge, and in interspaces) in a replicated field experiment in thirty-eight woodlands sites in the Great Basin Desert in UT, USA. Additionally, we potentially intensified the effects of tree islands …


The Tower Of Babel Account: A Linguistic Consideration, Dallin D. Oaks May 2015

The Tower Of Babel Account: A Linguistic Consideration, Dallin D. Oaks

Faculty Publications

The biblical account of the Tower of Babel has generally not been taken seriously by scholars in historical linguistics, but what are regarded by some as problematic aspects of the account may actually relate to claims that have been incorrectly attributed to the account. In fact, the account may not be reporting a sudden· and immediate confusion of languages, or even a sequence in which a confusion of languages led to a scattering of the people. Indeed, a close examination of the account seems to allow an interpretation of events that is compatible with what linguists have observed about [how …

The Experience Of Siblings Of Youth With Type 1 Diabetes, Stephanie Miller

Theses and Dissertations

Background. Type 1 diabetes requires intensive management, including blood glucose monitoring, carbohydrate counting and dietary modification, and administering insulin. When a child is diagnosed with type 1 diabetes, family dynamics are often altered as family schedules revolve around care for the child with diabetes. In addition, siblings face unique challenges as they become involved in the care of the child with type 1 diabetes. Therefore, it is important to understand experiences of siblings of youth with type 1 diabetes. Aims and Objectives. To identify experiences of siblings of children with type 1 diabetes from their own perspectives. Sample. As part …


P300 Latency In Alzheimer’S Disease: A Meta-Analysis And Meta-Regression, David Payne Bennett, Dawson Hedges Apr 2015

P300 Latency In Alzheimer’S Disease: A Meta-Analysis And Meta-Regression, David Payne Bennett, Dawson Hedges

Journal of Undergraduate Research

Developing a biomarker for accurate assessment and detection of Alzheimer’s disease was the goal of our research. The P300 component of the event-­‐related potential has been indicated to apparently change with the progression of Alzheimer’s disease. As measuring the P300 is non-­‐invasive and relatively easy, we sought to investigate abnormalities in the latency of the P300 in probable Alzheimer’s disease compared to healthy controls. Should such abnormalities be present, they would constitute a strong foundation for clinically significant biomarkers.


The Constitution: Who Knows, Who Cares?, Luke Bell, Jeremy Pope Apr 2015

The Constitution: Who Knows, Who Cares?, Luke Bell, Jeremy Pope

Journal of Undergraduate Research

In recent years, significant attention has been directed toward the role and relevance of the Constitution in contemporary politics. Conservative and Tea Party voters, for example, tout their dedication to the “founding principles” in the Constitution. Despite the prevalence of Constitutionally-charged rhetoric among political activists, national surveys have repeatedly found that most Americans are, at best, poorly informed about the nation’s founding document.

Going The Distance: The Pros And Cons Of Expanding Employees’ Global Knowledge Reach, Shad S. Morris Apr 2015

Going The Distance: The Pros And Cons Of Expanding Employees’ Global Knowledge Reach, Shad S. Morris

Faculty Publications

While some scholars have suggested MNEs to be superior to markets for managing knowledge across geographically distant boundaries, how they actually accomplish this has not been fully considered. We address this void by developing and testing a model that highlights the critical role of organizational incentives in enhancing employees’ internal search and use of knowledge. Data from 166 knowledge-intensive projects support our argument that, in contrast to process-based incentives that influence more local search, outcome-based incentives motivate employee teams to reach well beyond their immediate location, which in turn enhances performance. At the same time, we demonstrate that expanded reach …


The Gospel According To Nephi, Noel B. Reynolds Apr 2015

The Gospel According To Nephi, Noel B. Reynolds

Faculty Publications

2 Nephi 31 was written by Nephi as a grand finale to his small plates and was placed at the end to signal its premier importance. It is the centerpiece of his concluding sermon as signaled by a series of inclusios. It is presented as a flashback to the great vision received by both Lehi and Nephi in the first camp in the wilderness—over forty years earlier. But only here are we told for the first time that when Nephi witnessed the baptism of Jesus Christ in that early vision, he was simultaneously team-taught the gospel of Jesus Christ by …


Zeros Of Poincare Series Of Level 2, Andrew Haddock, Paul Jenkins Apr 2015

Zeros Of Poincare Series Of Level 2, Andrew Haddock, Paul Jenkins

Journal of Undergraduate Research

Introduction Poincaré series are a certain type of modular form. Modular forms are complex-valued functions that satisfy certain symmetry properties. There are many different types of modular forms, and one way to classify modular forms is by their level, such as 1, 2, 3, etc. They are of much interest as a research subject because they are connected in surprising ways to many different fields in number theory—e.g., elliptic curves, quadratic forms, and partition functions, to name just a few. As we gain more insight into the various properties of modular forms, we gain more insight into how these various …


Digital Outcrop Model And Paleoecology Of The Eight-Foot Rapid Algal Field (Middle Pennsylvanian Lower Ismay Sequence), Paradox Basin, Utah, Colton Goodrich, Scott Ritter Apr 2015

Digital Outcrop Model And Paleoecology Of The Eight-Foot Rapid Algal Field (Middle Pennsylvanian Lower Ismay Sequence), Paradox Basin, Utah, Colton Goodrich, Scott Ritter

Journal of Undergraduate Research

Although phylloid algal mounds have been studied for 50 year, much remains to be determined concerning the ecology and sedimentology of these Late Paleozoic carbonate buildups. Herein we perform a digital outcrop study of the well-known Middle Pennsylvanian Lower Ismay mound interval in the Paradox Basin because 1) the concept of phylloid algae was established in this interval and 2) outcropping mounds along the San Juan River are cited as outcrop analogs of reservoir carbonates in the Paradox Basin oil province of Utah and adjacent states. The principal field area is the Eight Foot algal field located at river mile …


Parameter Estimation For Towed Cable Systems Using Moving Horizon Estimation, Liang Sun, Jeremy Castagno, John Hedengren, Randall Beard Apr 2015

Parameter Estimation For Towed Cable Systems Using Moving Horizon Estimation, Liang Sun, Jeremy Castagno, John Hedengren, Randall Beard

Faculty Publications

This paper presents a strategy for optimal estimation of parameters for towed cable systems using moving horizon estimation (MHE). The main contributions of the work include a novel formulation of MHE using a dead-band that explicitly rejects measurement noise, real-time implementation results, and the investigation of time-varying stochastic disturbances as well as unknown yet constant disturbances. Further analysis is conducted on the observability and sensitivity of key parameters to determine which parameters can be estimated by the proposed approach using real-time streaming data from experiments. In addition to the real-time results, an offline multiobjective optimization is conducted to reveal the …


The Effects Of Classwide Function-Related Intervention Teams On Preschool Behavior, Krystine Alycia Jolstead Apr 2015

The Effects Of Classwide Function-Related Intervention Teams On Preschool Behavior, Krystine Alycia Jolstead

Theses and Dissertations

Challenging behavior in preschool is a serious concern for teachers. In recent years, positive behavior support (PBS) has been shown to be effective in reducing such behaviors. Class-Wide Function-related Intervention Teams (CW-FIT) is a specific program for implementing PBS principles in classroom settings. CW-FIT is a group contingency that utilizes social skills training, teacher praise, and positive reinforcement to improve student behavior. Students are taught specific social skills and then work in teams to earn a group reward based on the use of these skills. CW-FIT has been shown to be effective in elementary classrooms but has not yet been …
