  • Geometry of horizontal bundles and connections 

    Ryan, Justin M. (Wichita State University, 2014-05)
    An Ehresmann connection on a fiber bundle pi: E --> M is defined by prescribing a suitable horizontal subbundle H of the tangent bundle piT: TE --> E. For a horizontal bundle to be suitable, it must have a property called ...
  • Geometry of nonlinear connections 

    Parker, Phillip E.; Del Riego, L. (Elsevier Science B.V., Amsterdam, 2004-08-28)
    We show that locally diffeomorphic exponential maps can be defined for any second-order differential equation, and give a (possibly nonlinear) covariant derivative for any (possibly nonlinear) connection. We introduce ...
  • Growth rate and existence of solutions to Dirichlet problems for prescribed mean curvature equations on unbounded domains 

    Jin, Zhiren (Texas State University - San Marcos, 2008)
    We prove growth rate estimates and existence of solutions to Dirichlet problems for prescribed mean curvature equation on unbounded domains inside the complement of a cone or a parabola like region in Rn (n 2). The ...
  • The HANOHANO Detector and Ongoing Research and Development 

    Cicenas, Blake; Solomey, Nickolas (Elsevier, 2012)
    The Hanohano neutrino detector is a deep sea module that can be submerged to the ocean floor far away from surface radiation. Its Physics goals are the study of geo-neutrinos to probe the isotope source of the 45 TW of ...
  • Higgs boson Mass in GMSB with Messenger–Matter mixing 

    Albaid, Abdelhamid (Elsevier, 2012-12)
    A Higgs-like particle with mass of order 125 GeV has been observed by both ATLAS and CMS experiments. This Higgs mass causes sparticle masses in the several to multi-TeV range in the simple version of minimal GMSB models. ...
  • Higgs boson of mass 125 GeV in gauge mediated supersymmetry breaking models with matter-messenger mixing 

    Albaid, Abdelhamid; Babu, K. S. (American Physical Society, 2013-09-05)
    We investigate the effects of messenger-matter mixing on the lightest CP-even Higgs boson mass m(h) in gauge-mediated supersymmetry breaking models. It is shown that with such mixings m(h) can be raised to about 125 GeV, ...
  • A historical overview of connections in geometry 

    Freeman, Kamielle (Wichita State University, 2011-05)
    This thesis is an attempt to untangle/clarify the modern theory of connections in Geometry. Towards this end a historical approach was taken and original as well as secondary sources were used. An overview of the most ...
  • Holomorphic functions on subsets of C 

    Fridman, Buma L.; Ma, Daowei (Mathematical Society of Japan, 2013-01)
    Let Gamma be a C-infinity curve in C containing 0; it becomes Gamma(theta) after rotation by angle theta about 0. Suppose a C-infinity function f can be extended holomorphically to a neighborhood of each element of the ...
  • Hyperbolic vector random fields with hyperbolic direct and cross covariance functions 

    Du, Juan; Leonenko, Nikolai; Ma, Chunsheng; Shu, Hong (Taylor & Francis, 2012-06-26)
    This article introduces the hyperbolic vector random field whose finite-dimensional distributions are the generalized hyperbolic one, which is formulated as a scale mixture of Gaussian random fields and is thus an elliptically ...
  • Improved asymptotics of a decreasing mean residual life estimator 

    Lorenzo, Edgardo; Mukerjee, Hari (Taylor & Francis Group, 2014-09-17)
    The mean residual life of a life distribution, X, with a finite mean is defined by M(t) = E[X - t|X > t] for t > 0. Kochar etal. (2000) provided an estimator of M when it is assumed to be decreasing. They showed that its ...
  • Increased stability in the continuation of solutions to the Helmholtz equation 

    Hrycak, Tomasz; Isakov, Victor, 1947- (IOP Science, 2004-05-03)
    In this paper we give analytical and numerical evidence of increasing stability in the Cauchy Problem for the Helmholtz equation when frequency is growing. This effect depends on convexity properties of the surface where ...
  • Increased stability of solutions to the Helmholtz equation 

    Aralumallige, Deepak (Wichita State University. Graduate School., 2006-04-28)
  • Increased stability of solutions to the Helmholtz equation 

    Aralumallige, Deepak (2005-12)
    Study of the Cauchy problem for Helmholtz equation is stimulated by the inverse scattering theory and more generally by remote sensing. This thesis explains the increased stability of the Cauchy problem for Helmholtz ...
  • Inferences under a stochastic ordering constraint: The k-sample case 

    El Barmi, Hammou; Mukerjee, Hari (American Statistical Association, 2005-03)
    If X1 and X2 are random variables with distribution functions F1 and F2, then X1 is said to be stochastically larger than X2 if F1 ≤ F2. Statistical inferences under stochastic ordering for the two-sample case has a long ...
  • The inverse conductivity problem with limited data and applications 

    Isakov, Victor, 1947- (Institute of Physics, 2007)
    This paper describes recent uniqueness results in inverse problems for semiconductor devices and in the inverse conductivity problem. We remind basic inverse probelsm in semiconductor theory and outline use of an adjoint ...

    Myers, Joseph Kenneth (Wichita State University. Graduate School, 2010-04-23)
    Inverse doping profile problems are linked to inverse conductivity problems under the assumptions of zero space charge and low injection. Unipolar inverse conductivity problems are analyzed theoretically via three uniqueness ...
