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 from discrete sets and inverse problems
(Wichita State University, 202307)It is well known that every smooth surface S is at least locally generated by the Dirac equation with real potential. In this dissertation, we study the inverse problem of recovering this potential and surface based on ... 
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 ... 
Covariance matrix functions of isotropic vector random fields
(Taylor & Francis Group, 20140515)An isotropic scalar or vector random field is a secondorder random field in (d > 2), whose covariance function or direct/cross covariance functions are isotropic. While isotropic scalar random fields have been well developed ... 
Covariance structures of Gaussian and logGaussian vector stochastic processes
(Wichita State University, 201212)Although the covariance structures of univariate Gaussian and log Gaussian stochastic processes have been extensively studied in the past few decades, the development of covariance structures for Gaussian and logGaussian ... 
Coverage probability of tolerance levels
(Wichita State University, 201812)In this thesis the ideas of the tolerance limit and coverage probabilities are explored in the context of the Abasis and Bbasis for composite materials. The breaking strength of composite materials are random variables ... 
Crack detection in a three dimensional body
(200605)We propose a method of analyzing a crack in a three dimensional body. We treat the problem as an inverse problem and apply Green’s Theorem, Trace Theorem, and the Fredholm Alternative. We model the problem using Helmholtz ... 
Curvature and symmetries of closed fourmanifolds with a lower curvature bound
(Wichita State University, 202005)This thesis details homeomorphism classi cation theorems for closed, simply connected, Riemannian 4manifolds admitting an isometric circle action. We proceed by imposing progressively weaker curvature conditions, which ... 
Deep underground neutrino experiment (DUNE) near detector conceptual design report
(MDPI, 20210929)The Deep Underground Neutrino Experiment (DUNE) is an international, worldclass experiment aimed at exploring fundamental questions about the universe that are at the forefront of astrophysics and particle physics research. ... 
Deformations of Qcurvature II
(Springer, 20220211)This is the second article of a sequence of research on deformations of Qcurvature. In the previous one, we studied local stability and rigidity phenomena of Qcurvature. In this article, we mainly investigate the volume ... 
Derivation and regularization of corrections to propagators and vertices for cubically interacting scalar field theories
(Wichita State University, 201305)This thesis, a mainly expository work, attempts to give all the calculational details for some popular models in scalar quantum eld theory that serve a mostly pedagogical purpose. Starting with a real scalar eld with ... 
Design, construction and operation of the ProtoDUNESP liquid argon TPC
(IOP Publishing, 20220104)The ProtoDUNESP detector is a singlephase liquid argon time projection chamber (LArTPC) that was constructed and operated in the CERN North Area at the end of the H4 beamline. This detector is a prototype for the first ... 
Development of a neutrino detector capable of operating in space
(Elsevier B.V., 20230201)The vSOL experiment to operate a neutrino detector close to the Sun is building a small test detector to orbit the Earth to test the concept in space. This detector concept is to provide a new way to detect neutrinos ...
