The Hopf Conjecture with abelian symmetries
(Wichita State University, 2021-05)The Hopf Conjecture states that for closed, orietable, even-dimensional manifolds, the Euler characteristic is strictly positive. Results due independently to P uttmann and Searle [13] and Rong [14], and due to Rong and ... -
The NOvA far detector data acquisition system
(2014)Biery, Kurt, et al. "The NOvA Far Detector Data Acquisition System." Journal of Physics: Conference Series 513 no 1. doi:10.1088/1742-6596/513/1/012041. -
The relationship between preference and performance using three passive exoskeletons during simulated aircraft manufacturing tasks
(Wichita State University, 2022-04-29)Work-related musculoskeletal disorders (WMSDs) are the top workplace risk factors that impact the health of workers. In Kansas, there were 45,253 reported injuries/illnesses during the 2020 fiscal year. The main contributors ... -

Theodorsen's method: A numerical conformal map applied to fluid dynamics
(Wichita State University, 2023-05)The details of Theodorsen's method for computing the conformal map from the ex- terior of the unit disk to the exterior of a simple closed curve in the complex plane are reviewed. An implementation of the method in ... -
Theoretical results in inverse problems for size, solvability, and uniqueness in the p-n junction and doping profile of semiconductors
(2006-05)We present an overview of mathematical models for electrons and holes in semiconductors. We use these to pose some inverse problems for determining the doping profile of a semiconductor. We establish the solvability of ... -
A three-dimensional inverse gravimetry problem for ice with snow caps
(American Institute of Mathematical Sciences, 2013-05)We propose a model for the gravitational field of a floating iceberg D with snow on its top. The inverse problem of interest in geophysics is to find D and snow thickness g on its known (visible) top from remote measurements ... -
Time varying isotropic vector random fields on sphere
(Springer, 2017-12)For a vector random field that is isotropic and mean square continuous on a sphere and stationary on a temporal domain, this paper derives a general form of its covariance matrix function and provides a series representation ... -
Time-varying isotropic vector random fields on compact two-point homogeneous spaces
(Springer, 2018)A general form of the covariance matrix function is derived in this paper for a vector random field that is isotropic and mean square continuous on a compact connected two-point homogeneous space and stationary on a temporal ... -

Torus actions on simply connected 4-manifolds
(Wichita State University, 2017-05)In this paper, we study smooth effective actions of the 2-dimensional torus group T 2 ~= SO(2)xSO(2) on simply connected, closed 4-dimensional manifolds. Using the conical orbit space of the quotient, a cross-sectioning ... -
Torus actions, maximality, and non-negative curvature
(De Gruyter, 2021-09-03)Let $ℳ_0^n$ be the class of closed, simply connected, non-negatively curved Riemannian n-manifolds admitting an isometric, effective, isotropy-maximal torus action. We prove that if $M \in ℳ_0^n$ then M is equivariantly ... -
Translating vortex pairs with prescribed profiles
(Wichita State University. Graduate School, 2010-04-23)We generate translating vortex pairs with smooth or more arbitrary profiles that reflect modern vortex pairs being generated using prescribed domains of vorticity. Instead of prescribing the domain, we fix the area of the ... -
Two contributions to order restricted inferences
(Wichita State University, 2018-12)We are proposing two separate problems from order restricted inferences. The rst is a one-sided test for stochastic ordering of two distribution functions that protects against false positive conclusions because of model ... -
Typical points, invariant measures, and dimension for rational maps on the Riemann sphere
(2006-05)We present three original results for the dynamics of rational maps on the Riemann sphere. Using methods from dimension and ergodic theory, we discuss generalized physical measures and prove their existence for hyperbolic ... -
Unbiasedness of homogeneity test of normal mean vectors under multivariate order restrictions
(Wichita State University, 2017-05)This dissertation considers homogeneity test for comparing multivariate normal populations with generalized order restricted alternative hypothesis. The framework in this dissertation presents a generalized multivariate ... -
Unbiasedness of LRT on the homogeneity of means in MANOVA under general order restrictions
(Elsevier, 2019-05)In this paper a likelihood ratio test is developed through matrix projections for the hypothesis on the homogeneity of mean vectors in MANOVA. It is assumed that the mean vectors are under a general multivariate order ... -
Understanding the impact of improved hadron production measurements on accelerator neutrino particle beam flux uncertainties
(Wichita State University, 2019-12)One of the greatest challenges for neutrino experimentation is understanding the potential uncertainties in the collected data and models that are used for the Monte Carlo simulations. The neutrino-nucleus hadronic cross ... -
Unexpected radial limit
(Wichita State University, 2017-04-28)Consider a bounded solution ƒ of the prescribed mean curvature equation over a bounded domain Ω ⊂ R² which has a corner at which has a corner at (0, 0) of size 2α and assume the mean curvature of the graph of ƒ is bounded. ... -
Uniqueness and stability in the Cauchy Problem
(Springer, 2017)In this chapter we formulate and in many cases prove results on the uniqueness and stability of solutions of the Cauchy problem for general partial differential equations. One of the basic tools is Carleman-type estimates. ...
