An Investigation Into The Synthesis Of A Four-Armed Diamino Swallowtail, Christopher Carter Barnett Jan 2015

An Investigation Into The Synthesis Of A Four-Armed Diamino Swallowtail, Christopher Carter Barnett

Honors Theses

Perylenebisimides (PBIs) complex with quadruplex DNA and may influence the formation of telomeres. PBIs with amine groups are ionized at neutral pH and therefore soluble in water [1]. Swallowtails are long alkyl chains usually attached to PBIs to inhibit self-aggregation by pi-stacking [2]. Past attempts to create a PBI with swallowtails containing extra nitrogens were unsuccessful due to purification issues and methylene connectors. The purpose of this research is to investigate the synthesis of a diamino swallowtail with a methine connector. The first step is to create 1,3-bis(dibenzylamino)propan-2-one by way of an SN2 substitution reaction using 1,3-dichloroacetone and dibenzylamine [3]. …


Modelling Global Climate Variables With Cellular Automata Networks, David Robinson Jan 2015

Modelling Global Climate Variables With Cellular Automata Networks, David Robinson

Honors Theses

Cellular automata are discrete models that can be used to simulate many physical systems. Cellular automata have been used to model gas diffusion, different types of chemical reactions, population growth, and land use change over time. Recent research into cellular automata networks has shown that if sparse long range connections are added to a cellular automata, then it will exhibit properties of complex networks. Furthermore, research into modeling climate systems has shown that modeling the global climate as a complex network can be used to predict individual climate variables. In this work we attempt to connect these ideas by simulating …


Optimization: A Perspective On Improving An Ethylbenzene Production Design, Derrick C. Marchant Jan 2015

Optimization: A Perspective On Improving An Ethylbenzene Production Design, Derrick C. Marchant

Honors Theses

The goal of optimization in a chemical process or system involves improving an existing design or a combination of devices. In the case of an established process such as the ethylbenzene production process investigated here, the optimization involves improving an established process and choosing the best available case within a set of constraints that also considers maximizing the economic bottom line. An objective function must be selected for an optimization problem which defines the achievable goal. The objective function of the optimization process presented here is to minimize the estimated annual operating cost (EAOC). An EAOC takes in to account …


County Chairs Speak Out: How Mississippi's County Party Organizations Connect With Voters, Phillip C. Waller Jan 2015

County Chairs Speak Out: How Mississippi's County Party Organizations Connect With Voters, Phillip C. Waller

Honors Theses

This paper includes the results of a qualitative study of 11 Mississippi county party chairs interviewed about their role in the state and how that role has been affected by redistricting. I highlight their comments on their perceived roles, organizational purpose, voter outreach strategies, competition, voter turnout and state and county relationships. Though I started my project hoping to focus on the effects of redistricting on county party organizations' outreach to voters, only 3 of the 11 county chairs I interviewed significantly changed their actions after the 2011 redistricting cycle. The only county chairs who mentioned major changes in their …


Initial Breakdown Pulses In Lightning Flashes, Emily Morgan Smith Jan 2015

Initial Breakdown Pulses In Lightning Flashes, Emily Morgan Smith

Honors Theses

Initial Breakdown (IB) pulses in lightning flashes have been observed since 1937. Using two sensor arrays to determine the location and amplitude of IB pulses, this study examines the largest IB pulse in 55 flashes with 23 pulses from intracloud (IC) flashes and 32 pulses from cloud-to-ground (CG) flashes. The two goals of this project were (1) to compare the range-normalized amplitude of the largest IB pulse to its altitude, duration, and timing within each flash, and (2) to characterize the shapes of the IB pulses. Since all lightning flashes seem to begin with IB pulses, this study is aimed …


Optimization Of An Ethylbenzene Process, Garrison Padgett Morgan Jan 2015

Optimization Of An Ethylbenzene Process, Garrison Padgett Morgan

Honors Theses

In industry, chemical plants should be running at optimal performance in order to maximize profit. However, this is frequently not the case. Optimization is the process of improving an existing situation, device, or, in the case of chemical engineers, a chemical process. Furthermore, there are numerous strategies to optimize a chemical process, and it is up to the engineer to decide what to change in order to make the optimization worthwhile. Last semester, I was able to show my knowledge of optimization by applying changes to an existing ethylbenzene producing plant. I simulated the base case for this plant and …


Zeros Of Modular Forms And Quantum Unique Ergodicity, Steve Lester Dec 2014

Zeros Of Modular Forms And Quantum Unique Ergodicity, Steve Lester

Dynamical Systems Seminar

Modular forms appear prominently in number theory and also come into play in other areas of mathematics as well as physics. In this talk I will mention some basic properties of modular forms and describe the distribution of their zeros. In particular, I will discuss how Quantum Unique Ergodicity for Hecke cusp forms is related to the equidistribution of their zeros. This talk will assume no previous knowledge of the subject and should be accessible to graduate students with some background in analysis.

Supplemental Educational Services (Ses): Effects Of Ses Tutoring On Student Achievement, Jennifer Misewicz, Douglas E. Carothers Dec 2014

Supplemental Educational Services (Ses): Effects Of Ses Tutoring On Student Achievement, Jennifer Misewicz, Douglas E. Carothers

Journal of Contemporary Research in Education

This study examined the effectiveness of Supplemental Educational Services (SES) tutoring in increasing the reading and mathematics achievement of Title I students in a Florida elementary school. Kindergarten through fifth grade students who had been matched on their previous performance on the Florida Assessment in Reading (FAIR) or the District Baseline Math test were grouped based on voluntary participation or non-participation in SES tutoring. Scores on the same tests were then compared after the conclusion of SES tutoring. Results showed no gains in improvement for students who received SES tutoring relative to students who did not participate in SES tutoring. …


Achievement Gaps And The Doubly Disadvantaged: The Intersection Of Socioeconomic Status And Race/Ethnicity On Math And Reading Trajectories, Littisha A. Bates Dec 2014

Achievement Gaps And The Doubly Disadvantaged: The Intersection Of Socioeconomic Status And Race/Ethnicity On Math And Reading Trajectories, Littisha A. Bates

Journal of Contemporary Research in Education

Numerous studies have examined both the income and race/ethnic achievement gaps. These gaps are particularly striking in the case of minority children, who are more likely than their non- Hispanic white counterparts to be living in poverty. This overlap in achievement gaps makes it difficult to clearly identify the most disadvantaged children. Using two designations in No Child Left Behind (NCLB), socioeconomic status and race/ethnicity, this study examines math and reading trajectories as children move through elementary school. Applying multilevel growth curves to four waves of the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99, I examine the intersection of …


A Comparison Of Ell And Non-Ell Students’ And Guardians’ Perceptions Of Student Led Conferences, Charlotte Orso, Bryan Morgan Dec 2014

A Comparison Of Ell And Non-Ell Students’ And Guardians’ Perceptions Of Student Led Conferences, Charlotte Orso, Bryan Morgan

Journal of Contemporary Research in Education

The purpose of the study was to determine if the ELL and non-ELL students’ and guardians’ perceptions of student-led conferences were similar. The sample included 97 consenting guardians and 90 students from five fifth grade classrooms. The student and guardian participants were given parallel surveys to ascertain their perceptions of student-led conferences. The survey data were analyzed with the two one-sided significance test (TOST) technique to determine statistical significance. Additionally, 90% confidence intervals were constructed and analyzed to verify the results. Six of the nine student survey questions resulted in statistically equivalent perceptions between the ELL and non-ELL participants. Four …

On The Excursion Probabilities Of Gaussian Random Fields, Yimin Xiao Oct 2014

On The Excursion Probabilities Of Gaussian Random Fields, Yimin Xiao

Probability & Statistics Seminar

Excursion probabilities of Gaussian random fields have many applications in statistics (e.g., scanning statistic and control of false discovery rate (FDR)) and in other areas. In this talk, we consider the excursion probabilities of two types of multivariate Gaussian random fields: those with smooth sample functions, and those with non-smooth (or fractal) sample functions. An important class of such random fields are those with Matérn cross-covariance functions studied by Gneiting, Kleiber, and Schlather (2010). For smooth Gaussian random fields, it is shown that the “Expected Euler Characteristic Heuristic” still holds; and nonsmooth Gaussian random fields, we prove an asymptotic result …


Random Matrix Models, Non-Intersecting Random Paths, And The Riemann-Hilbert Analysis, Andrei Martinez-Finkelshtein Oct 2014

Random Matrix Models, Non-Intersecting Random Paths, And The Riemann-Hilbert Analysis, Andrei Martinez-Finkelshtein

Colloquium

Random matrix theory (RMT) is a very active area of research and a great source of exciting and challenging problems for specialists in many branches of analysis, spectral theory, probability, and mathematical physics. The analysis of the eigenvalue distribution of many random matrix ensembles leads naturally to determinantal point processes and, in particular, to biorthogonal ensembles where the correlation kernel is written in terms of two sequences of mutually orthogonal functions. Another source of determinantal point processes is a class of stochastic models of particles following non-intersecting paths. The connection of these models with RMT is tight: for example, the …

On Rural-Urban Differences In Human Capital Formation: Finding The ‘Bottlenecks’, Elton Mykerezi, Genti Kostandini, Jeffery L. Jordan, Ilda Melo Jul 2014

On Rural-Urban Differences In Human Capital Formation: Finding The ‘Bottlenecks’, Elton Mykerezi, Genti Kostandini, Jeffery L. Jordan, Ilda Melo

Journal of Rural Social Sciences

Studies have found lower levels of educational achievement for students in rural areas focusing mostly on cross-sectional data. Using the 1997 National Longitudinal Survey of Youth, we follow the same youth cohort to examine whether there are metro-nonmetro gaps in high cognitive achievement, high school graduation, college readiness, degree attainment, and earnings. We find that gaps emerge early in life and they remain constant through high school.In addition,results suggest that rural students graduate from high school at the same rate as their urban counterparts, but they fall behind when it comes to college graduation rates. Growing up in a rural …
