#### Testing The Equality Of Regression Coefficients And A Pooling Methodology From Multiple Samples When The Data Is Multicollinear

(Mathematics, 2009-09-16)

Testing the equality of regression coefficients between two regression equations is a common practice in statistics today. The theory and methods are sufficiently developed under ordinary least squares (OLS) estimation. ...

#### Analysis And Simulation In Neuron And Fibrosis Models

(Mathematics, 2009-09-16)

In this work, we use analysis and numerical simulations to study the change of collective behaviorof two synaptically coupled square bursting systems, the effect of noise inan elliptic bursting system and foreign body ...

#### The Uniqueness Of Minimal Acyclic Complexes

(Mathematics, 2009-09-16)

In this paper, we discuss conditions for uniqueness among minimal acyclic complexes of finitely generated free modules over a commutative local ring which share a common syzygy module. Although such uniqueness occurs over ...

#### A Study On The B Family Of Shallow Water Wave Equations

(Mathematics, 2009-09-16)

In this dissertation we study b family of shallow water wave equations which include classical Korteweg-de Vries, Camassa-Holm and Degasperis-Procesi equations. We first establish the models of the Camassa-Holm and ...

#### A Modified Greenberg Speed-flow Traffic Model

(University of Texas at Arlington, 2008)

A modified Greenberg speed-flow model is proposed. We assume speed is a logarithmic function of free-flow speed, concentration and a minimum constant density. Optimization techniques are used to maximize the flow. Taylor's ...

#### LES For Wing Tip Vortex Around An Airfoil

(Mathematics, 2007-08-23)

The wing tip vortex is very important because of its effects on the noise generation, blade/vortex interactions on helicopter blades, propeller cavitations on ships, and other fields. The objective of this work is to use ...

#### Estimating Absolute Transcript Concentration For Microarrays Using Langmuir Adsorption Theory

(Mathematics, 2008-08-08)

This paper estimates the Langmuir parameters for probe on microarray then improves estimation of absolute transcript concentration using Langmuir adsorption model. We use the spike-in probes found on commercial microarrays, ...

#### Minkowski's Inequality for Convex Curves

(University of Texas at Arlington, 2001-05)

Minkowski's inequality is a relation between mixed areas of two curves and their respective areas. The concept of mixed area is defined. A variational technique is used to give a proof of Minkowski's inequality. As a special ...

#### Logistic Regression With Misclassified Covariates Using Auxiliary Data

(Mathematics, 2009-09-16)

When standard regression methods are used, measurement errors cause a bias in parameters estimation. In dealing with discrete covariates, such measurement errors are known as misclassification and the corresponding discrete ...

#### A Globally Convergent Numerical Method For Coefficient Inverse Problems

(Mathematics, 2009-09-16)

In our terminology "globally convergent numerical method" means a numerical method, whose convergence to a good approximation for the correct solution is independent of the initial approximation. A new numerical imaging ...
