• #### A comparison of some numerical conformal mapping methods for simply and multiply connected domains ﻿

(American Institute of Mathematical Sciences, 2019-01)
This paper compares some methods for computing conformal maps from simply and multiply connected domains bounded by circles to target domains bounded by smooth curves and curves with corners. We discuss the use of explicit ...
• #### Composite optimal control for interconnected singularly perturbed systems ﻿

(Wichita State University, 2017-05)
This dissertation deals with the design of a decentralized control and estimators for large scale interconnected singularly perturbed stochastic systems for system stabilization and cost minimization. Singular perturbation ...
• #### Computation of plane potential flow past multi-element airfoils using conformal mapping, revisited ﻿

(Wichita State University, 2018-05)
Calculations of potential ow and pressure over multi-element airfoils are studied, using conformal maps. A composition of classical Karman-Tre tz maps is used to smooth out the trailing edge corners successively, from ...
• #### Computation of Stokes waves using conformal mapping ﻿

(Wichita State University, 2016-05)
In this paper we study the time dependent water wave problem for Stokes waves on water of infinite and finite depth using numerical conformal mapping techniques. We begin by briefly reviewing Fornberg's numerical conformal ...

(Wichita State University, 2010-12)
• #### Concept study for observing galactic neutrinos in Neptune’s atmosphere ﻿

(Wichita State University, 2022-05)
I discuss the feasibility of a conceptual space-based neutrino detector that utilizes the Ice Giants as targets for galactic neutrinos. The purpose of this research stems from the concept of wanting to find a new method ...
• #### Conformal capacity and polycircular domains ﻿

(Elsevier, 2022-09-13)
We study numerical conformal mapping of multiply connected planar domains with boundaries consisting of unions of finitely many circular arcs, so called polycircular domains. We compute the conformal capacities of condensers ...
• #### Conformal deformation of a conic metric ﻿

(Wichita State University, 2011-05)
The problem studied here focuses on a compact manifold M without boundary in which the Riemannian metric g is on Λ = M – {p1, p2,…,pκ}. Near the pi 's, g has a particular type of singularity in which locally M = (0, δ)x ...
• #### Conformally variational riemannian invariants ﻿

(American Mathematical Society, 2019-06-01)
Conformally variational Riemannian invariants (CVIs), such as the scalar curvature, are homogeneous scalar invariants which arise as the gradient of a Riemannian functional. We establish a wide range of stability and ...
• #### Conjectures in inverse boundary value problems for quasilinear elliptic equations ﻿

(Department of Mathematics of the Universidad de la Frontera Temuco-Chile and the Department of Mathematics of the Universidade Federal de Pernambuco, Recife-Brazil, 2005-12)
Inverse boundary value problems originated in early 80’s, from the contribution of A.P. Calderon on the inverse conductivity problem [C], in which one attempts to recover the electrical conductivity of a body by means ...
• #### Conjugate loci of pseudo-Riemannian 2-step nilpotent Lie groups with nondegenerate center ﻿

(Springer, 2005)
We determine the complete conjugate locus along all geodesics parallel or perpendicular to the center (Theorem 2.3). When the center is one-dimensional we obtain formulas in all cases (Theorem 2.5), and when a certain ...
• #### Consistent Estimation of Distributions with Type II Bias with Applications in Competing Risks Problems ﻿

(Institute of Mathematical Statistics, 2004-02)
A random variable X is symmetric about 0 if X and -X have the same distribution. There is a large literature on the estimation of a distribution function (DF) under the symmetry restriction and tests for checking this ...
• #### Consistent estimation of survival functions under uniform stochastic ordering; the k-sample case ﻿

(Elsevier B.V., 2016-02)
Let S-1, S-2, ... , S-k be survival functions of life distributions. They are said to be uniformly stochastically ordered, S-1 <=(uso) S-2 <=(uso) ... <=(uso) S-k, if S-i/Si+1 is a survival function for 1 <= i <= k - 1. ...
• #### Constrained pole placement by linear quadratic modification ﻿

(IEEE, 1991-06-26)
A noniterative method is introduced that will enable the designer to find an optmal one step state feedback controller. The controller will place the eigenvalues of the closed loop system in a specified disk.
• #### Constraints on oscillation parameters from $\nu_e$ appearance and $\nu_\mu$ disappearance in NOvA ﻿

(American Physical Society, 2017-06-05)
Results are reported from an improved measurement of $\nu_\mu \rightarrow \nu_e$ transitions by the NOvA experiment. Using an exposure equivalent to $6.05\times10^{20}$ protons-on-target 33 $\nu_e$ candidates were observed ...
• #### Constraints on the distance moduli, helium, and metal abundances, and ages of globular clusters from their RR Lyrae and non-variable horizontal branch stars. II. multiple stellar populations in 47 Tuc, M3, and M13 ﻿

(IOP Publishing, 2017-11-10)
We present a new set of horizontal branch (HB) models computed with the MESA stellar evolution code. The models adopt alpha-enhanced Asplund et al. metal mixtures and include the gravitational settling of He. They are used ...
