Computational Studies On Mechanisms And Reactivity Of Mercury And Cobalt Organometallic Reactions, Jack Terrell Fuller Jul 2016

Computational Studies On Mechanisms And Reactivity Of Mercury And Cobalt Organometallic Reactions, Jack Terrell Fuller

Theses and Dissertations

Density Functional Theory (DFT) is a powerful tool for treating large organometallic structures efficiently and accurately. DFT calculations on the Hg-catalyzed oxidation of methane to methyl bisulfate in sulfuric acid suggest the lowest energy pathway involves a closed-shell electrophilic C–H activation mechanism coupled with metal alkyl reductive functionalization and oxidation by SO3. Comparison to Tl, Zn, and Cd suggests that Hg is unique in its ability to catalyze this set of reaction steps. Comparison to K2S2O8 highlights the selectivity of this C–H activation reaction as opposed to radical conditions. In contrast, DFT calculations indicate that CoIII(TFA)3 oxidizes methane through a …

A Corpus-Based Comparison Of The Academic Word List And The Academic Vocabulary List, Jacob Andrew Newman Jul 2016

A Corpus-Based Comparison Of The Academic Word List And The Academic Vocabulary List, Jacob Andrew Newman

Theses and Dissertations

Research has identified the importance of academic vocabulary (e.g., Corson, 1997; Gardner, 2013; Hsueh-chao & Nation, 2000). In turn, many researchers have focused on identifying the most frequent and salient words present in academic texts across registers and presenting these words in lists, such as The Academic Word List (AWL) (Coxhead, 2000). Gardner and Davies (2014), recognizing the limitations of the AWL, have developed a new list known as The Academic Vocabulary List (AVL). This present study examines the appearance of the 570 AWL word families and the top 570 AVL word families in the Academic Textbook Corpus (ATC) – …

Synthesis And Biological Evaluation Of Small Molecule Inhibitors Of Bmpr1b, Paulo Andre Machicao Tello Jul 2016

Synthesis And Biological Evaluation Of Small Molecule Inhibitors Of Bmpr1b, Paulo Andre Machicao Tello

Theses and Dissertations

Methods for preparing an array of potential small molecule inhibitors of Bone Morphogenetic Protein Receptor 1b (BMPR1b) are described. Target molecules were prepared from two general classes: (1) N9-aryl-N6-ureidoadenines, and (2) dicarbamyl iodoacetamides. Recent data from the Peterson lab indicated that both classes might bind to BMPR1b and thus inhibit this key receptor. Docking studies performed using Sureflex Dock suggested the N9-aryl-N6-ureidoadenines would bind to the active site of BMPR1b. In addition antiproliferative activities of dicarbamyl iodoacetamides previously synthesized in the Peterson lab pointed to this moiety as an attractive target for structure activity relationship (SAR) development. Compounds were prepared …

Theoretical And Experimental Investigation Of A Quadspectral Nonlinearity Indicator, Kyle Glen Miller Jul 2016

Theoretical And Experimental Investigation Of A Quadspectral Nonlinearity Indicator, Kyle Glen Miller

Theses and Dissertations

Understanding the impact of jet noise and other high-amplitude sound sources can be improved by quantifying the nonlinearity in a signal with a single-microphone measurement. An ensemble-averaged, frequency-domain version of the generalized Burgers equation has been used to derive a quantitative expression for the change in spectral levels (in decibels) over distance due to geometric spreading, thermoviscous absorption, and nonlinearity, respectively. The nonlinearity indicator, called νN , is based on the quadspectral Morfey-Howell indicator, which has been used in the past to characterize nonlinearity in noise waveforms. Unlike the Morfey-Howell indicator, the νN indicator has direct physical significance, giving a …

Embracing Multiplicity: Autobiographical Personae In Ruth Hall, Gina Marie Schneck Jul 2016

Embracing Multiplicity: Autobiographical Personae In Ruth Hall, Gina Marie Schneck

Theses and Dissertations

Sara Payson Willis Eldredge Farrington Parton, more famously known as the elusive Fanny Fern, employs three autobiographical personae mediated by fiction in her debut novel, Ruth Hall: (1) Ruth Hall, the novel's protagonist; (2) Floy, the fictional Ruth's pseudonym; and (3) Fanny Fern, Parton's real-life pseudonym and the name under which Ruth Hall was published. Together these personae assert a fragmented presence that incorporates various voices and lives, allowing for exploration, growth, and interactivity.Philippe Lejeune's autobiographical contract outlines three specific guidelines for autobiography—that it be a narrative, that it explore personal history, and that it link author and protagonist. Ruth …

The Impact Of Shortening A Long Survey On Response Rate And Response Quality, Daniel Stephen Allen Jul 2016

The Impact Of Shortening A Long Survey On Response Rate And Response Quality, Daniel Stephen Allen

Theses and Dissertations

Many factors influence the response rate of a survey or questionnaire. The BYU alumni questionnaire was initially a lengthy survey with over 200 questions. After a short version of the questionnaire was created and administered, response rates appear to have increased substantially. Male respondents appear particularly more inclined to respond to the shortened version compared to the long version. The questionnaire is examined through various statistical analyses and compared between the short and long versions. Results are presented in the context of existing research on response rates and response quality.

Developmental Math Students' Calibrated Judgments Of Learning, Brian Lindley Jones Jul 2016

Developmental Math Students' Calibrated Judgments Of Learning, Brian Lindley Jones

Theses and Dissertations

Calibrated Judgments of Learning (CJOL) represent the degree to which students' judgments of learning (JOL) relate to their actual learning. Although a substantial amount of research has been conducted on calibration and JOL in various domains of psychology, only a growing number of studies have begun to address the use of CJOL in applied educational settings. This study investigated the use of CJOL in university developmental math courses. Study participants included 185 men and 100 women with ages ranging from 18 to 61 years (M = 23.48, SD = 5.95). Study results indicate that these developmental math students were fairly …

Phonetic Shift /Ɔr/ Phonemic Change? American English Mergers Over 40 Years, Joseph A. Stanley, Margaret E. L. Renwick Jul 2016

Phonetic Shift /Ɔr/ Phonemic Change? American English Mergers Over 40 Years, Joseph A. Stanley, Margaret E. L. Renwick

Faculty Publications

In this paper we analyze the vowel formants of a speaker over four decades to show phonemic change through time. Other real-time studies (Harrington, Palethorpe & Watson 2000; Harrington & Reubold 2015) have found that the vowel spaces of UK English speakers shift over the lifetime, likely as a consequence of interaction with speakers of other dialects or social classes. We focus on an understudied variety of English, spoken in the western United States, to investigate a pair of phonological mergers, the cord-card merger and the hoarse-horse merger.

Modeling Of Acoustic Resonators And Resonator Systems For Use In Passive Noise Control, Matthew Franklin Calton Jun 2016

Modeling Of Acoustic Resonators And Resonator Systems For Use In Passive Noise Control, Matthew Franklin Calton

Theses and Dissertations

Acoustic resonators, such as the Helmholtz and quarter-wave resonator, can be used to attenuate unwanted noise in an enclosed space. Classical formulations can be used to approximate resonator performance for a given resonator configuration, but may lack sufficient accuracy for some applications. This research aims to improve the analytical characterization of resonators to provide better correlation to experimental results. Using higher-order approximations and proper end corrections, more accuracy can be obtained in calculating the impedance and resonance frequency of a single resonator, which will then carry over into the overall configuration of the model. The impedance of a system of …

Criteria For Selecting Pegylation Sites On Proteins For Higher Thermodynamic Stability, Paul B. Lawrence Jun 2016

Criteria For Selecting Pegylation Sites On Proteins For Higher Thermodynamic Stability, Paul B. Lawrence

Theses and Dissertations

PEGylation of protein side-chains has been used for more than 30 years to enhance the pharmacokinetic properties of protein drugs, and has been enabled by the recent development of many chemoselective reactions for protein side-chain modification. However, there are no structure- or sequence-based guidelines for selecting sites that provide optimal PEG-based pharmacokinetic enhancement with minimal loss to biological activity. Chapter 1 is a brief introduction to protein PEGylation. In chapter 2 we use the WW domain of the human protein Pin 1 (WW) as a model system to probe the impact of PEG on protein conformational stability. Using a combination …

American Spread Option Pricing With Stochastic Interest Rate, An Jiang Jun 2016

American Spread Option Pricing With Stochastic Interest Rate, An Jiang

Theses and Dissertations

In financial markets, spread option is a derivative security with two underlying assets and the payoff of the spread option depends on the difference of these assets. We consider American style spread option which allows the owners to exercise it at any time before the maturity. The complexity of pricing American spread option is that the boundary of the corresponding partial differential equation which determines the option price is unknown and the model for the underlying assets is two-dimensional.In this dissertation, we incorporate the stochasticity to the interest rate and assume that it satisfies the Vasicek model or the CIR …

Poe's Entangled Fiction: Quantum Field Theory In "The Colloquy Of Monos And Una" And "The Mystery Of Marie Rogêt", Jean A. Little Jun 2016

Poe's Entangled Fiction: Quantum Field Theory In "The Colloquy Of Monos And Una" And "The Mystery Of Marie Rogêt", Jean A. Little

Theses and Dissertations

When seen among the constellation of Edgar Allan Poe's works culminating in Eureka, "The Colloquy of Monos and Una" and "The Mystery of Marie Rogêt," take on an important role as vehicles for scientific contemplation. Similar to early quantum physicists, such as Einstein and Schrödinger, Poe uses macro-level analogies to explore the unity of individual entities, which becomes an important tenet of his explanation of the universe. His thought experiments also resemble those of modern physics in their approach to reality as probabilistic, an idea that finds its echo in quantum field theory, which distinguishes between observed particles and their …

Student Growth Trajectories With Summer Achievement Loss Using Hierarchical And Growth Modeling, Sara Bernice Chapman Jun 2016

Student Growth Trajectories With Summer Achievement Loss Using Hierarchical And Growth Modeling, Sara Bernice Chapman

Theses and Dissertations

Using measures of student growth has become more popular in recent years—especially in the context of high stakes testing and accountability. While these methods have advantages over historical status measures, there is still much evidence to be gathered on patterns of growth generally and in student subgroups. To date, most research studies dealing with student growth focus on the effectiveness of specific interventions or examine growth in a few urban areas. This project explored math, reading, and English language arts (ELA) growth in the students of two rural school districts in Utah. The study incorporated hierarchical and latent growth methods …

The Asynchronous T-Step Approximation For Scheduling Batch Flow Systems, David R. Grimsman Jun 2016

The Asynchronous T-Step Approximation For Scheduling Batch Flow Systems, David R. Grimsman

Theses and Dissertations

Heap models in the max-plus algebra are interesting dynamical systems that can be used to model a variety of tetris-like systems, such as batch flow shops for manufacturing models. Each heap in the model can be identified with a single product to manufacture. The objective is to manufacture a group of products in such an order so as to minimize the total manufacturing time. Because this scheduling problem reduces to a variation of the Traveling Salesman Problem (known to be NP-complete), the optimal solution is computationally infeasible for many real-world systems. Thus, a feasible approximation method is needed. This work …

Duplicate With Choose: Using Statistics For Fault Mitigation, Jon-Paul Anderson Jun 2016

Duplicate With Choose: Using Statistics For Fault Mitigation, Jon-Paul Anderson

Theses and Dissertations

This dissertation presents a novel technique called duplicate with choose (DWCh) which is a modification of the fault detection technique duplicate with compare (DWC). DWCh adds a smart decider block to DWC that monitors the duplicated circuits and decides which circuit is fault free when a fault occurs. If chosen correctly, DWCh is able to mask faults at a lower cost than conventional techniques like TMR.This dissertation derives reliability expressions for DWCh showing that under ideal conditions its reliability exceeds the most commonly used fault masking technique for spacecraft, triple modular redundancy. For non-ideal conditions, DWCh provides a lower cost …

Optimum Pick Point Locations For Straight, Singly Symmetric Steel Plate Girders, J. Andrew Pratt Jun 2016

Optimum Pick Point Locations For Straight, Singly Symmetric Steel Plate Girders, J. Andrew Pratt

Theses and Dissertations

Optimal pick point location is discovered in order to have the full buckling capacity of a suspended, non-prismatic, singly symmetric plate girders. The results show that a significant increase in stability occurs at the pick point location of 0.25L, where L is the span length. This recommendation can be utilized in the field to save construction cost and time because of how simplistic it is to use. A finite element software, ABAQUS 6.14, is used to determine the buckling capacities at different pick point locations and of different cross sections. The dimension of the cross sections and span lengths for …

Cooperative Estimation For A Vision-Based Multiple Target Tracking System, Joshua Y. Sakamaki Jun 2016

Cooperative Estimation For A Vision-Based Multiple Target Tracking System, Joshua Y. Sakamaki

Theses and Dissertations

In this thesis, the Recursive-Random Sample Consensus (R-RANSAC) algorithm is applied to a vision-based, cooperative target tracking system. Unlike previous applications, which focused on a single camera platform tracking targets in the image frame, this work uses multiple camera platforms to track targets in the inertial or world frame. The process of tracking targets in the inertial frame is commonly referred to as geolocation.In practical applications sensor biases cause the geolocated target estimates to be biased from truth. The method for cooperative estimation developed in this thesis first estimates the relative rotational and translational biases that exist between tracks from …

Glutamate And Gaba Receptor-Mediated Plasticity In The Mesolimbic Dopamine System By Alcohol, Ashley Cerise Nelson Jun 2016

Glutamate And Gaba Receptor-Mediated Plasticity In The Mesolimbic Dopamine System By Alcohol, Ashley Cerise Nelson

Theses and Dissertations

Alcoholism is a devastating chronic relapsing disorder with significant costs to individuals and society. The mesolimbic dopamine (DA) system plays an important role in regulating reward and addiction. GABA neurons located in the ventral tegmental area (VTA) regulate VTA DA neuron activity, and are a relevant target for alcohol in the brain. VTA GABA neurons exhibit marked hyperexcitability during withdrawal from ethanol. Past research has demonstrated that the motivational effects of opiates cause a change in VTA GABA(A) receptors in opiate-dependent animals, which switch from a GABA-induced hyperpolarization of GABA neurons to a GABA-induced depolarization. The focus of this study …
