Modeling, Simulation, And Applications Of Fractional Partial Differential Equations, Wilson Cheung

Theses and Dissertations

The Black-Scholes model is commonly used to track the price of European options with respect to maturity in many financial markets. This model degenerates into a partial differential equation that relates the European-style option price to the underlying price and time of expiry. Black-Scholes assumes that underlying prices satisfy a geometric Brownian motion.

After the U.S. stock market crash of 1987, this assumption becomes inaccurate as it fails to represent the behavior of S&P 500 European vanilla option prices. Specifically, under the measure of moneyness, the volatility smirk does not flatten out and the resulting conditional return distribution does not …

The Visual Priming Of Motion-Defined 3d Objects, Xiong Jiang, Yang Jiang, Raja Parasuraman

Behavioral Science Faculty Publications

The perception of a stimulus can be influenced by previous perceptual experience, a phenomenon known as perceptual priming. However, there has been limited investigation on perceptual priming of shape perception of three-dimensional object structures defined by moving dots. Here we examined the perceptual priming of a 3D object shape defined purely by motion-in-depth cues (i.e., Shape-From-Motion, SFM) using a classic prime-target paradigm. The results from the first two experiments revealed a significant increase in accuracy when a "cloudy" SFM stimulus (whose object structure was difficult to recognize due to the presence of strong noise) was preceded by an unambiguous SFM …

Elliott Carter’S March: An Applicable Analysis, Troy W. Palmer

Mahurin Honors College Capstone Experience/Thesis Projects

This thesis, in summation, can be divided into two parts. The first half focuses on the story of Eight Pieces for Four Timpani, composed by Elliott Carter and published in 1968. Both its compositional and performance history are addressed. The compositional history starts with the writing of the first version of Carter’s music, Six Pieces for Kettledrums, written in 1950; next, the revision process is addressed, including the actual revisions seen in March. The performance history consists of a study done to determine which piece from the Eight Pieces is the most performed piece; to the author’s …

Anxiety, Uncertainty, Distress Tolerance, And Eating Disorder Symptoms As Related To Non-Suicidal Self-Injury In Young Adults, Mandi L. Martin

Mahurin Honors College Capstone Experience/Thesis Projects

Adolescents and college-aged individuals are particularly at risk for non-suicidal self-injury (NSSI) and eating disorders. Research is lacking regarding the cognitive and emotional factors behind the formation and maintenance of both types of pathology. This study examines anxiety, intolerance to uncertainty (IU), and distress tolerance in relation to both constructs in two separate samples (Sample 1: n=364, 58.5% freshmen, 75.8% female; Sample 2: n=156, 52.6% freshman, 66.0% female) with 32.4% and 40% reporting any history of NSSI, respectively. Participants completed a packet of questionnaires regarding the variables of interest and were debriefed and referred as necessary. In the first sample, …

Spectroscopy And Chemometrics For Cultural Heritage And Forensics: Conservation Of Magnetic Tape By Identifying Degraded Polymer Signatures; And Characterizing The Chemiluminescent Reaction Of Luminol With Blood, Brianna Marie Cassidy

Theses and Dissertations

The first half of this manuscript focuses on the identification of degraded magnetic tape using attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and multivariate statistics. For several decades before the digital era, magnetic tape was the dominant audio and visual recording medium. A majority of magnetic tapes contain polyester urethane (PEU) binders, which are known to degrade via hydrolysis, making the retrieval of recorded data difficult and at times impossible. Degraded tapes are currently identified through visual inspection followed by playback on vintage equipment. However, if degraded tapes are played, they are likely to stick and shed onto player …

Development Of Ultra-Low Loading Of Compressive Pt Lattice Cathode Catalyst On Highly Stable Support For Pemfc Automotive Applications, Tianyuan Xie

Theses and Dissertations

The major barriers in the commercialization of the fuel cell technology for automotive applications are the cost and durability of the Pt catalyst and the support stability at high potentials. The U.S. Department of Energy (DOE) targets direct hydrogen fuel cell systems for transportation to meet 65% peak-efficiency, 5,000 hour durability with a mass production cost of $40/kW by 2020. Currently in 2015, the system can be operated at peak energy efficiency of 60% for 3,900 hours with cost of $55/kW. To meet these targets, precious metal loadings must be greatly reduced without altering the catalyst stability. The primary objective …

Wavelet Analysis Of Periodic Error In Heterodyne Interferometry, Chao Lu

Theses and Dissertations

Heterodyne displacement measuring interferometry provides important metrology for applications requiring high resolution and accuracy. Heterodyne Michelson interferometers use a two-frequency laser source and separate the two optical frequencies into one fixed length and one variable length path via polarization. Ideally these two beams are linearly polarized and orthogonal so that only one frequency is directed toward each path. An interference signal is obtained by recombining the light from the two paths; this results in a measurement signal at the heterodyne (split) frequency of the laser source. This measurement signal is compared to the optical reference signal. Motion in the measurement …

Low-Intensity Physical Activity And Cardiometabolic Risk Factors Among Older Adults With Multiple Chronic Conditions, Yueyao Li

Theses and Dissertations

Introduction Cardiovascular disease (CVD) is the leading cause of death among older adults in the Unites States and is driven largely by cardiometabolic risk factors including elevated blood pressure and blood glucose. Studies have found the protective effect of moderate intensity physical activity (MIPA) and vigorous intensity physical activity (VIPA) on cardiometabolic risk factor; however, the association between light physical activity (LIPA) and cardiometabolic risk factor among older adults is not clear. Objectives 1). Examine the association between LIPA and cardiometabolic risk factors. 2). Examine whether the association between LIPA and cardiometabolic risk factor is moderated by multiple chronic conditions. …

Financial Crises And Government Regulation, Yusef Trad

Honors Thesis

In the midst of turmoil, regulation is “a rule or directive made and maintained by an authority” to maintain order. More often than not, the authoritative figure that imposes and upholds regulatory standards, following its introduction to the specific industry or firm, is the government of the respective country or region. However, politicians, like the rest of us, are unable to predict when a crisis will occur and what appropriate regulation should be imposed to prevent that crisis. Thus, an inevitable concern with regulation is the fact that it is unable to thwart an unforeseeable future crisis but is instead …

Numerical And Experimental Investigations Of Dam And Levee Failure, Ezzat Youssef Elhassan Mohamed Elalfy

Theses and Dissertations

Both numerical and experimental investigations are conducted to study the failure of earthen dams and levees. Boussinesq equations describing one-dimensional unsteady flow including non-hydrostatic pressure distribution are solved numerically along with Exner equation for the sediment mass conservation to include the effects of the streamline curvature on the failure of non-cohesive earthen embankments. In addition, the effects of the steep bottom slope on the flow variables during the failure are studied by solving the Saint- Venant equations modified for steep bed slope along with the Exner equation to simulate non-cohesive earthen embankment failure due to overtopping. The Boussinesq equations are …

Identity, Critical Agency, And Engineering Majors: An Affective Model For Predicting Engineering As A Career Choice., Allison Godwin, Geoff Potvin, Zahra Hazari, Robynne Lock

School of Engineering Education Faculty Publications

Prior to college, many students do not have experience with engineering, but some ultimately choose an engineering career. Additionally, women choose engineering at lower rates than men, which results in women’s underrepresentation. The framework of critical engineering agency (CEA) is utilized to understand student attitudes and beliefs for choosing engineering. We investigate the relationships among students’ math and physics identities in high school that predict choice of engineering careers; how students’ beliefs about science and technology predict a choice of engineering careers; whether these beliefs are different by gender; and how well CEA explains students’ engineering choice. The data were …

The Performance Of Random Prototypes In Hierarchical Models Of Vision, Kendall Lee Stewart

Dissertations and Theses

I investigate properties of HMAX, a computational model of hierarchical processing in the primate visual cortex. High-level cortical neurons have been shown to respond highly to particular natural shapes, such as faces. HMAX models this property with a dictionary of natural shapes, called prototypes, that respond to the presence of those shapes. The resulting set of similarity measurements is an effective descriptor for classifying images. Curiously, prior work has shown that replacing the dictionary of natural shapes with entirely random prototypes has little impact on classification performance. This work explores that phenomenon by studying the performance of random prototypes on …

Molecules And Metals In The Distant Universe: Sub-Mm And Optical Spectroscopy Of Quasar Absorbers, Sean Stephen Morrison

Theses and Dissertations

In order to gain a complete understanding of galaxy formation and evolution, knowledge of the atomic and molecular gas in the interstellar medium (ISM) is required. Absorption-line spectroscopy of quasars offers a powerful and luminosity independent probe of gas in distant galaxies. The Damped Lyman- systems (DLAs; 20.3 . log NHI ), are the highest neutral hydrogen column density quasar absorbers and contain a substantial fraction of the neutral gas available for star formation in the high-redshift Universe. This thesis presents a study of the metal content in some DLAs, based on optical spectroscopy, and a search for molecules based …

Integration Of Impulse-Variability Theory And The Speed-Accuracy Trade-Off In Children's Multijoint Ballistic Skill Performance, Sergio Lupe Molina

Theses and Dissertations

A major purpose of the motor learning and motor control literature is to provide principles and theories (e.g., speed-accuracy trade-off) that can inform the instruction of young learners in motor skill competence. To be optimally effective, these principles and theories must be understood and applied in relation to authentic instructional contexts, complex motor patterns, and specific developmental levels of young learners. It is insufficient, for instance, to generalize research results with adults learning simple movements in controlled laboratory settings to an understanding of how children learn from fundamental movement skills in physical education classes. Based on this premise, the work …

Industrial Robot Acceptance: Effects Of Workforce Demographics And Establishing A Culture Of Acceptance Within Manufacturing Industry, Melissa M. Henderson

Theses and Dissertations

Industrial applications have not been extensively researched regarding human-robot interaction. This project investigated industrial robot acceptance in the context of one manufacturing site. Acceptance was examined in relation to the workforce and conditions of acceptance were identified using mixed methodology. Quantitative (surveys) and qualitative (interviews) data was used to measure and analyze the existing state of technology acceptance and site culture. Based on this exploratory study, it was found the manufacturing facility has a weak culture but would be generally accepting of industrial robots if the technology were easy to use and useful. The identified boundary conditions to acceptance included …

Optical Spectroscopy And Chemometrics For Discrimination Of Dyed Textile Fibers And Magnetic Audio Tapes, Nathan C. Fuenffinger

Theses and Dissertations

This dissertation focuses on the application of both novel and standard chemometric approaches toward societal problems of interest in the areas of forensic science and cultural heritage preservation. Microspectrophotometry (MSP), a technique enabling measurements of absorption of electromagnetic radiation by microscopic materials in the ultraviolet-visible (UV-Vis) region, is widely used by forensic examiners for comparisons of metameric textile fibers. These comparisons are often hindered, however, by the raw or normalized spectra showing little detail or having few points of comparison. Derivative preprocessing can enhance structure in some instances. We have demonstrated through the use of multivariate statistics that derivatives are …

Exploring The Professional Beliefs Of An Efl Teacher: A Narrative Inquiry, Seyyed Ali Ostovar-Namaghi, Shabnam Norouzi, Mobina Hosseini

The Qualitative Report

The applied science model of teacher education implies that the relationship between theory and practice is unidirectional. In this study, however, the researchers make a case in the opposite direction, i.e., they believe that professional practice can also shed some light on theories of language teaching. Since narrative inquiry is best for capturing the detailed stories or life experiences of a single life, the researchers took it as a legitimate mode of research to uncover and make sense of the professional experience of an experienced and professionally popular language teacher. Analysis revealed six themes, which reflect the participant’s professional beliefs. …

Experimental Study Of Longitudinal Sorting Of Particles Differing In Size And Density, Nabila Mahjabeen

Theses and Dissertations

Transport, deposition and erosion of sediment particles differing in size, shape and density may result in particle segregation, which in geosciences applications is generally referred to as sediment sorting. A thorough understanding of sediment sorting processes is important to describe and model a wide variety of natural processes such as the decrease in particle size and/or density in a fluvial system (downstream fining and/or lightening), the formation of economic placers, concentration of heavy minerals, chemical and metal pollutants etc. Sorting of sediment grains associated with sediment transport in the streamwise direction results in the development of longitudinal sorting patterns. Vertical …

Post-Fall Decision Making Among Older Women Living In Continuing Care Retirement Communities: A Mixed Methods Study, Caroline D. Bergeron

Theses and Dissertations

Introduction: One in every three adults over the age of 65 experiences a fall every year, with women experiencing more falls than men. Falls can affect how older women perceive themselves and their independence. The purpose of this study was to examine older women's health decision making after experiencing a fall. Methods: I conducted semi-structured interviews with 17 older women living independently in continuing care retirement communities (CCRCs) who had experienced a fall within the previous six months and 11 individuals the women identified as being involved in their post-fall decision making. I also conducted an exploratory survey on post-fall …

Statistical Power In Meta-Analysis, Jin Liu

Theses and Dissertations

Statistical power is important in a meta-analysis study, although few studies have examined the performance of simulated power in meta-analysis. The purpose of this study is to inform researchers about statistical power estimation on two sample mean difference test under different situations: (1) the discrepancy between the analytical power and the actual power and (2) the influence of unequal sample size and unbalanced design on the power. Results indicated that there are noticeable discrepancies between the estimated power and actual power under certain conditions. In general, unbalanced design decreases the statistical power in the meta-analysis. Recommendations are provided for researchers …

Preparation And Characterization Of Pt-Ru Bimetallic Catalysts Using Electroless Deposition Methods And Mechanistic Study Of Re And Cs Promoters For Ag-Based, High Selectivity Ethylene Oxide Catalysts, Weijian Diao

Theses and Dissertations

Pt-Ru bimetallic catalysts are widely used for direct methanol fuel cells, biomass upgrading and hydrocarbon refining and offer unique properties compared to Pt or Ru monometallic catalysts due to ensemble effects, electronic effects, and/or bifunctional effects. To achieve better performance, strong metal-metal interactions and true bimetallic surface are needed. Electroless deposition (ED) methods are used in our laboratory to synthesize such bimetallic catalysts. In this study, two series of Ru@Pt/C (Pt deposited on Ru surfaces) and Pt@Ru/C (Ru deposited on Pt surfaces) catalysts have been synthesized. Characterization data from temperature programmed reduction (TPR), selective chemisorption, X-ray photoelectron spectroscopy (XPS), and …
