      In this paper, direct numerical simulation (DNS) of flow transition over a flat plate at a free stream Mach number of 0.5 and a Reynolds number of 1000 based on the free stream velocity and inflow displacement thickness ...
    • The Least-squares Finite Element Method For Grid Deformation And Meshfree Applications 

      Fleitas, Dionisio Laeber (Mathematics, 2007-08-23)
      Grid adaptation is often needed to improve the numerical solution of a Partial Differential Equation (PDE), due to, for example, shock waves and boundary layers. In moving boundary problems, the grid needs to be regenerated ...

    • On The Image Of The Totalling Functor 

      Beck, Kristen Ann (Mathematics, 2007-08-23)
      Let A denote a DG algebra and k a field. The totalling functor, from the category of chain complexes over the graded A-modules to the catagory of DG modules over A, can be extended to one between their derived categories. ...
    • LES For Wing Tip Vortex Around An Airfoil 

      Cai, Jiangang (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 ...
    • Qualitative Behavior Of Dynamical Vector Fields 

      Kirby, Roger Dale (Mathematics, 2007-09-17)
      Differential Equations come in two classes, deterministic and stochastic. The first part of this analysis establishes the stable properties of the set of all trajectories converging on a critical point in the real plane ...
    • On Progenitively Koszul Commutative Rings 

      Stern, Paul Russell (Mathematics, 2008-04-22)
      This paper introduces and identifies classes of progenitively Koszul rings. A progenitively Koszul ring is a commutative ring that admits a Koszul complex A=K(R) that is formal, and such that the homology algebra H(A) ...
    • Uniform Weighted Compact / Non-compact Schemes For Shock / Boundary Layer Interaction 

      Xie, Peng (Mathematics, 2008-08-08)
      The critical problem of CFD is perhaps an accurate approximation of derivatives for a given discrete data set. Based on our previous work on the weighted compact scheme (WCS), a uniform weighted compact / non-compact scheme ...
    • Estimating Absolute Transcript Concentration For Microarrays Using Langmuir Adsorption Theory 

      Mo, Min (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, ...
    • The Impact Of Vaccination And Multiple Types Of HPV On Cervical Cancer 

      Crawford, Britnee A. (Mathematics, 2008-09-17)
      Understanding the relationship between multiple strains of human papillomavirus and cervical cancer may play a key role in vaccination strategies for the virus. In this article we formulate a model with two strains of ...
    • Large Deviation Principle For Functional Limit Theorems 

      Oprisan, Adina (Mathematics, 2009-09-16)
      We study a family of stochastic additive functionals of Markov processes with locally independent increments switched by jump Markov processes in an asymptotic split phase space. Based on an averaging limit theorem, we ...
    • Logistic Regression With Misclassified Covariates Using Auxiliary Data 

      Dong, Nathan N. (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 ...
    • Non-traditional Socio-mathematical Norms In Undergraduate Real Analysis 

      Dawkins, Paul Christian (Mathematics, 2010-03-03)
      This study builds upon the framework of classroom norms (Cobb, Wood, & Yackel, 1993) and socio-mathematical norms (Cobb & Yackel, 1996) to understand how non-traditional socio-mathematical norms influence student reasoning ...
    • On The Existence Of Totally Reflexive Modules 

      Beck, Kristen Ann (Mathematics, 2011-07-14)
      In this manuscript, we investigate the existence of non-free totally reflexive modules over two classes of commutative local (Noetherian) rings.First, we demonstrate existence over a class of local rings which are defined ...
