A computing method for multivariate isotonic regression
(Wichita State University, 201012) 
Computing the logarithmic capacity of compact sets having (infinitely) many components with the charge simulation method
(Springer Link, 20230228)We apply the charge simulation method (CSM) in order to compute the logarithmic capacity of compact sets consisting of (infinitely) many “small” components. This application allows to use just a single charge point for ... 
Concept for a spacebased nearsolar neutrino detector
(Elsevier B.V., 20230401)The concept of putting a neutrino detector in close orbit of the Sun has been unexplored until very recently. The primary scientific return is to vastly enhance our understanding of the solar interior, which is a major ... 
Concept study for observing galactic neutrinos in Neptune’s atmosphere
(Wichita State University, 202205)I discuss the feasibility of a conceptual spacebased 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, 20220913)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, 201105)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, 20190601)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 TemucoChile and the Department of Mathematics of the Universidade Federal de Pernambuco, RecifeBrazil, 200512)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 pseudoRiemannian 2step 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 onedimensional 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, 200402)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 ksample case
(Elsevier B.V., 201602)Let S1, S2, ... , Sk be survival functions of life distributions. They are said to be uniformly stochastically ordered, S1 <=(uso) S2 <=(uso) ... <=(uso) Sk, if Si/Si+1 is a survival function for 1 <= i <= k  1. ... 
Constrained pole placement by linear quadratic modification
(IEEE, 19910626)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, 20170605)Results are reported from an improved measurement of $\nu_\mu \rightarrow \nu_e$ transitions by the NOvA experiment. Using an exposure equivalent to $6.05\times10^{20}$ protonsontarget 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 nonvariable horizontal branch stars. II. multiple stellar populations in 47 Tuc, M3, and M13
(IOP Publishing, 20171110)We present a new set of horizontal branch (HB) models computed with the MESA stellar evolution code. The models adopt alphaenhanced Asplund et al. metal mixtures and include the gravitational settling of He. They are used ... 
Construction and solution of an inverse problem posed by "Piekara’s Chair"
(Wichita State University, 200805)The article "Piekara's Chair: Mechanical Model for Atomic Energy Levels" by Zofia GolabMeyer presents a model of the realworld problem of determining classical energy states suitable for high school or undergraduate ... 
Construction industrial multivariate statistical analysis based on real estate market in USA
(Wichita State University, 20160429)This project mainly focus on how the land market value, in terms of GDP, CPI, construction cost index and unemployment rate, inflation rate, population and purchasing manage index, enables a relationship with the real ... 
Continuation of solutions of elliptic systems from discrete sets with application to geometry of surfaces
(Wichita State University, 201807)We obtain new estimates of stability for continuation of solutions of elliptic inequali ties  ∂u2 < = au2 from finite discrete sets. For this we use Hormander's type of Carleman estimates for ∂bar with boundary ... 
A convergent algorithm for a generalized multivariate isotonic regression problem
(Springer, 201202)Sasabuchi et al. (Biometrika 70(2):465472, 1983) introduces a multivariate version of the wellknown univariate isotonic regression which plays a key role in the field of statistical inference under order restrictions. ... 
Convex configurations for solutions to semilinear elliptic problems in convex rings
(Taylor & Francis Group, LLC, 200605)For a given convex ring and an L 1 function f:Ω × → + we show, under suitable assumptions on f, that there exists a solution (in the weak sense) to with {x Ω: u(x) > s} Ω1 convex, for all s (0, M). 
Covariance matrices for secondorder vector random fields in space and time
(IEEE, 20110501)This paper deals with vector (or multivariate) random fields in space and/or time with secondorder moments, for which a framework is needed for specifying not only the properties of each component but also the possible ...
