    • A Computational Study on Horizontal Pipe Flows with Multiple Crossflow Inlets 

      Torres, Hilario C (2014-08)
      Computational fluid dynamics was used to investigate the flow in pipes with multiple crossflow inlets as several geometric and boundary condition parameters were varied. The varied parameters included the spacing between ...
    • A Hidden Markov Renewal Model 

      Preston, Benjamin 1981- (2015-12-01)
      Hidden semi-Markov models (HSMMs) are a powerful class of statistical model that have been applied to a wide range of areas such as speech recognition, protein structure prediction, Internet-traffic modeling, financial ...
    • Active Manipulation of Acoustic Fields and Applications 

      Platt, Eric Brian 1985- (2017-12-11)
      In this thesis we present the research performed in the last three and a half years concerning frequency domain control of acoustic and electromagnetic fields through secondary exterior sources or arrays. We will discuss ...
    • EXTERIOR REGULARIZED HARMONIC AND HARMONIC FUNCTIONS 

      Han, Qi 1980- (2012-08)
      This thesis mainly studies harmonic functions on exterior regions, having compact, Lipschitz boundaries, in our new finite energy function space, via the sequence of exterior harmonic Steklov eigenvalues and associated ...
    • Large Time Step and Overlapping Grids for Conservation Laws 

      Jegdic, Ilija 1983- (2014-05)
      One focus of this dissertation is to construct a large time step Finite Volume Method for computing numerical solutions to hyperbolic systems of conservation laws. We also consider a method of overlapping spatial grids for ...
    • New Insights on Quasistatic and Acoustic Cloaking 

      Meklachi, Taoufik 1978- (2014-05)
      In the first four chapters 1-4, we study, in the quasistatic regime, the behavior of the dissipated power inside the boundary layers of a two dimensional metamaterial slab of negative permittivity . We consider a compactly ...
    • Solutions of Equations for the Regulation of Kinase Activity in a Finite Cylindrical Cell 

      Liu, Puchen 1979- (2013-12)
      In this work, inspired by the reality in organisms and particularly the shape of axon of the neuron, new mathematical models of regulation of kinase activity are presented. In the view of mathematician, those models ...
    • Steklov Eigenproblems and Approximations of Harmonic Functions 

      Cho, Manki 1984- (2014-08)
      In this work, we provide explicit formulae for harmonic Steklov eigenvalues and associated Steklov eigenfunctions by solving a Steklov eigenproblem on bounded rectangles. This allows the description of all the Steklov ...
    • Study of Flow Interaction Between Multiple Stages in Long Horizontal Wells 

      Jha, Pranab Narayan (2015-01-06)
      Numerical simulation of flow inside a horizontal wellbore with multiple completion stages is presented. The aim was to study the blocking effect on the toe-end stages observed in long horizontal wells. An axisymmetric pipe ...
    • Unconstrained Variational Principles and Morse Indices for Linear Elliptic Eigenproblems 

      Rivas, Mauricio Alexander 1984- (2013-12)
      Variational principles for finding eigenvalues, and associated eigenvectors, for symmetric matrices and compact self-adjoint linear operators have been studied by many authors for some time now. Here we shall introduce ...
    • Well-Posedness for Weak Solutions of Axisymmetric Div-Curl Systems 

      Lopez, Juan Francisco 1989- (2018-05-04)
      We study the axisymmetrc div-curl system on bounded volumes of revolution with normal and tangential boundary conditions. This vector system of equations arises in classical field theories. In particular, the electrostatic ...
