Ut Pictura Poesis And The Relationship Between Poetry And Painting During The Renaissance, Shannon O'Donoghue

The Pegasus Review: UCF Undergraduate Research Journal

This essay explores ut pictura poesis as a renaissance art theory. The main objective of Renaissance artists and art critics who promoted the theory was to raise painting to the status of a liberal art by comparing it to the honored art of poetry. Ideas linking the relationship between the arts of painting and poetry during the Renaissance formed from ancient treatises by Horace and Aristotle. The humanistic theory, popular during the Renaissance, related poetry and painting in the artists? common goal to imitate and then ?perfect? or idealize nature. To show that leading artists were consciously aware of this …

House Vs. Home: Defining Place Through Identity, Ryan Gleason

Electronic Theses and Dissertations

A house is a place of safety. A home is a place of belonging. Though different a house always desires to become a home, but it can only be so through a connection to self. It is a home that is an extension of one's identity. Through the mirror, which is the home, and through an understanding of schema theory a person's being can be understood through one's ideas, place, self, family, rituals, memories, and feelings. Each of these factors act as a layer of brick building a strong foundation or a crackling fireplace adorned with family portraits making the …

Resonant Anisotropic Emission In Rabbitt Spectroscopy, Bejan M. Ghomashi

Honors Undergraduate Theses

A variant of RABBITT pump-probe spectroscopy in which the attosecond pulse train comprises both even and odd harmonics of the fundamental IR probe frequency is explored to measure time-resolved photoelectron emission in systems that exhibit autoionizing states. It is shown that the group delay of both one-photon and two-photon resonant transitions is directly encoded in the energy-resolved photoelectron anisotropy as a function of the pump-probe time-delay. This principle is illustrated for a 1D model with symmetric zero-range potentials that supports both bound states and shape-resonances. The model is studied using both perturbation theory and solving the time-dependent Schodinger equation on …

Quantitative Line Assignment In Optical Emission Spectroscopy, Jessica Chappell

Electronic Theses and Dissertations

Quantitative elemental analysis using Optical Emission Spectroscopy (OES) starts with a high level of confidence in spectral line assignment from reference databases. Spectral interferences caused by instrumental and line broadening decrease the resolution of OES spectra creating uncertainty in the elemental profile of a sample for the first time. An approach has been developed to quantify spectral interferences for individual line assignment in OES. The algorithm calculates a statistical interference factor (SIF) that combines a physical understanding of plasma emission with a Bayesian analysis of the OES spectrum. It can be used on a single optical spectrum and still address …

A Behavioral Model Of Law Enforcement Applicant Characteristics Derived From A Simulated Cheating Task: Implications For Pre-Employment Hiring Practices, Julian Montaquila

Electronic Theses and Dissertations

Recently, numerous high-profile instances of police misconduct and corruption have been thrust into the national spotlight. Hiring police officers who will act with integrity and not betray public trust remains essential. The present research experimentally examines this phenomenon by evaluating pre-employment assessment results against applicant performance on a simulated cheating task (i.e., The Dots Task) in order to derive information to improve contemporary pre-employment screening and selection models. Four case examples are presented which depict malicious actors who possessed privileged access, assumed no one would ever scrutinize their activities, and attempted to leverage a lack of oversight for their personal …

Systematic Review And Meta-Analysis: Tuberculosis, Tnfα Inhibitors, And Crohn's Disease, Brent L. Cao

Honors Undergraduate Theses

Inflammation is often a protective reaction against harmful foreign agents. However, in many disease conditions, the mechanisms behind the inflammatory response are poorly understood. Often times, the inflammation causes adverse effects, such as joint pain, abdominal pain, fever, fatigue, and loss of appetite. Thus, many treatments aim to inhibit the inflammatory response in order to control adverse symptoms. Such treatments include TNFα inhibitors. However, a major risk associated with drugs inhibiting tumor necrosis factor alpha (TNFα) is serious infection, including tuberculosis (TB).

Anti-TNFα therapy is used to treat patients with Crohn’s disease, for which the risk of tuberculosis may be …

Unlike these techniques, SLLF is yet one of the same family as schlieren photography, it is capable of non-intrusive …

Generation And Characterization Of Isolated Attosecond Pulse In The Soft X-Ray Regime, Jie Li

Electronic Theses and Dissertations

The observation of any atomic and molecular dynamics requires a probe that has a timescale comparable to the dynamics itself. Ever since the invention of laser, the temporal duration of the laser pulse has been incrementally reduced from several nanoseconds to just attoseconds. Picosecond and femtosecond laser pulses have been widely used to study molecular rotation and vibration. In 2001, the first single isolated attosecond pulse (1 attosecond = 10^-18 seconds.) was demonstrated. Since this breakthrough, "attoscience" has become a hot topic in ultrafast physics. Attosecond pulses typically have span between EUV to X-ray photon energies and sub-femtosecond pulse duration. …

Effect Of Nonclassical Optical Turbulence On A Propagating Laser Beam, Melissa Beason

Electronic Theses and Dissertations

Theory developed for the propagation of a laser beam through optical turbulence generally assumes that the turbulence is both homogeneous and isotropic and that the associated spectrum follows the classical Kolmogorov spectral power law of κ-11/3. If the atmosphere deviates from these assumptions, beam statistics such as mean intensity, correlation, and scintillation index could vary significantly from mathematical predictions. This work considers the effect of nonclassical turbulence on a propagated beam. Namely, anisotropy of the turbulence and a power law that deviates from κ-11/3. A mathematical model is developed for the scintillation index of a Gaussian beam propagated through nonclassical …

A Machine Learning Approach To Assess The Separation Of Seismocardiographic Signals By Respiration, Brian Solar

Honors Undergraduate Theses

The clinical usage of Seismocardiography (SCG) is increasing as it is being shown to be an effective non-invasive measurement for heart monitoring. SCG measures the vibrational activity at the chest surface and applications include non-invasive assessment of myocardial contractility and systolic time intervals. Respiratory activity can also affect the SCG signal by changing the hemodynamic characteristics of cardiac activity and displacing the position of the heart. Other clinically significant information, such as systolic time intervals, can thus manifest themselves differently in an SCG signal during inspiration and expiration. Grouping SCG signals into their respective respiratory cycle can mitigate this issue. …

The Effect Of Mismatch Primers On The Efficiency Of Amplification In Quantitative Polymerase Chain Reactions, Molly C. Dawkins

Honors Undergraduate Theses

Polymerase chain reaction (PCR) is a method used in many research protocols to amplify a small amount of a short segment of DNA to millions of copies. PCR is used for many taxonomic studies, as well as for some medical diagnostic procedures. Through PCR, short DNA primers bind to the template DNA to allow the thermostable DNA polymerase to copy the DNA. Often, researchers create universal primers to target a conserved region of DNA in multiple species, for example, the 16S rRNA gene in bacteria. The problem with these universal primers is that they do not always perfectly match the …
