#### Nucleation and growth : modeling the NH3 - HCL reaction

Contributor:Shinn, Jaime M.

Date Submitted:2012

Date Submitted:2012

One of the trademarks of a Liesegang ring system is the exhibition of a moving reaction front to form a periodic precipitation pattern. This phenomenon has been studied by both chemists and mathematicians. The periodic ...

#### Integrated mathematics/science activity for secondary students : development, implementation, and student feedback, An

Contributor:Gentry, Abigail Rose

Date Submitted:2016

Date Submitted:2016

Mathematics teachers are often challenged by their students to give reasoning for why learning mathematics is necessary. An approach to address this question is to show students the value in learning mathematics by ...

#### Anomaly detection in terrestrial hyperspectral video using variants of the RX algorithm

Contributor:Schwickerath, Anthony N.

Date Submitted:2012

Date Submitted:2012

There is currently interest in detecting the use of chemical and biological weapons using hyperspectral sensors. Much of the research in this area assumes the spectral signature of the weapon is known in advance. ...

#### Linear systems and Riemann-Roch theory on graphs

Contributor:James, Rodney

Date Submitted:2010

Date Submitted:2010

Graphs can be viewed as discrete counterparts to algebraic curves, as exemplified by the recent Riemann-Roch formula for integral divisors on multigraphs. We show that for any subring R of the reals, the Riemann-Roch ...

#### Abelian surfaces with real multiplication over finite fields

Contributor:Freese, Hilary

Date Submitted:2014

Date Submitted:2014

Given a simple abelian surface A/Fq, the endomorphism algebra, End(A) ⊗ Q, contains a unique real quadratic subfield. We explore two different but related questions about when a particular real quadratic subfield K+ is the ...

#### Intersections of ψ classes on Hassett spaces of rational curves

Contributor:Sharma, Nand

Date Submitted:2018

Date Submitted:2018

Hassett spaces are moduli spaces of weighted stable pointed curves. In this work, we consider such spaces of curves of genus 0 with weights all 1/q , q being a positive integer greater than or equal to 2. These spaces are ...

#### Multidimensional scaling : infinite metric measure spaces

Contributor:Kassab, Lara

Date Submitted:2019

Date Submitted:2019

Multidimensional scaling (MDS) is a popular technique for mapping a finite metric space into a low-dimensional Euclidean space in a way that best preserves pairwise distances. We study a notion of MDS on infinite metric ...

#### Steady state Hopf mode interaction in anisotropic systems

Contributor:Maple, Jennifer

Date Submitted:2013

Date Submitted:2013

A paradigm example of pattern formation in anisotropic extended systems is the electroconvection of nematic liquid crystals, due to its easily accessible control parameters and the variety of patterns near onset. Some of ...

#### Pattern formation in reaction diffusion systems and ion bombardment of surfaces

Contributor:Hashmi, Bahaudin A.

Date Submitted:2017

Date Submitted:2017

We have analyzed pattern formation in two different systems: (1) Vapor-to-particle reaction diffusion systems and (2) Highly ordered square arrays in ion bombardment. The vapor-to-particle reaction exhibits oscillatory ...

#### Flag of best fit as a representative for a collection of linear subspaces, The

Contributor:Marrinan, Timothy P.

Date Submitted:2013

Date Submitted:2013

This thesis will develop a technique for representing a collection of subspaces with a flag of best fit, and apply it to practical problems within computer vision and pattern analysis. In particular, we will find a nested ...
