A compressive sensing approach to solving nonograms
(20130710)A nonogram is a logic puzzle where one shades certain cells of a 2D grid to reveal a hidden image. One uses the sequences of numbers on the left and the top of the grid to figure out how many and which cells to shade. We ... 
A construction of hyperkähler metrics through RiemannHilbert problems
(20150729)In 2009 Gaiotto, Moore and Neitzke presented a new construction of hyperkähler metrics on the total spaces of certain complex integrable systems, represented as a torus fibration M over a base space B, except for a divisor ... 
A criterion for toric varieties
(20130815)We consider the pair of a smooth complex projective variety together with an anticanonical simple normal crossing divisor (we call it "log Calabi Yau"). Standard examples are toric varieties together with their toric ... 
A localnonlocal transmission problem
(20150507)We consider solutions to some elliptic equations which change abruptly across a smooth interface. The main equation of interest, motivated by applications to atmospheric dynamics, is local on one side of this interface and ... 
A quadrature EulerianLagrangian WENO scheme for reservoir simulation
(20150814)This dissertations focuses on solving the advection problem with the motivation of simulating transport in porous media. A quadrature based EulerianLagrangian scheme is developed to solve the nonlinear advection problem ... 
Abelian ChernSimons theory with toral gauge group, modular tensor categories, and group categories
(20120906)Classical and quantum ChernSimons with gauge group U(1)N were classified by Belov and Moore in [BM05]. They studied both ordinary topological quantum field theories as well as spin theories. On the other hand a correspondence ... 
About the largest subsolution for a free boundary problem in R²
(20111221)We analyze the geometry and regularity of the largest subsolution of a Free Boundary Problem. We showed that the largest subsolution is a viscosity solution of (1) with Lipschitz and NonDegenerate properties under a very ... 
Accuracy of RNASeq and its dependence on sequencing depth
(BMC Bioinformatics, 20141215)Background: The cost of DNA sequencing has undergone a dramatical reduction in the past decade. As a result, sequencing technologies have been increasingly applied to genomic research. RNASeq is becoming a common technique ...

Adiabatic limits of the Hermitian YangMills equations on slicewise stable bundles
(20080828)Not available 
Agents' agreement and partial equilibrium pricing in incomplete markets
(20120925)We consider two riskaverse financial agents who negotiate the price of an illiquid indivisible contingent claim in an incomplete semimartingale market environment. Under the assumption that the agents are exponential ... 
Algebra readiness : building strong foundations through conceptual understanding
(20120203)Algebra readiness has been a topic of much research and debate. This report summarizes findings pertaining to how researchers and experts in the field of mathematics education define the term algebra readiness. The Southern ... 

Alternative estimation approaches for some common Item Response Theory models
(20110106)In this report we give a brief introduction to Item Response Theory models and multilevel models. The general assumptions of two classical Item Response Theory, 1PL and 2PL models are discussed. We follow the discussion ... 
An analogue of the KorkinZolotarev lattice reduction for vector spaces over number fields
(20101214)We show the existence of a basis for a vector space over a number field with two key properties. First, the nth basis vector has a small twisted height which is bounded above by a quantity involving the nth successive ... 
Analysis of a DarcyStokes system modeling flow through vuggy porous media
(20080828)Not available 
Analysis of errors and improvements in numerical approximations and methods in secondary mathematics curriculum
(20130830)This report discusses three topics relating to errors of numerical methods and to improvements of numerical approximations. The introduction connects these topics to the secondary mathematics curriculum. The three chapters ... 
Analysis of geometric flows, with applications to optimal homogeneous geometries
(20110706)This dissertation considers several problems related to Ricci flow, including the existence and behavior of solutions. The first goal is to obtain explicit, coordinatebased descriptions of Ricci flow solutionsespecially ... 
Analysis of Ricci flow on noncompact manifolds
(20130502)In this dissertation, we present some analysis of Ricci flow on complete noncompact manifolds. The first half of the dissertation concerns the formation of TypeII singularity in Ricci flow on [mathematical equation]. For ... 
Analysis of the real line
(20120202)The purpose of this report is to describe the course, Analysis of the Real Line, taught at The University of Texas at Austin. Course materials are presented using the inquiry based learning method. Students work a series ...
