Stationary time series resulting from certain positive definite kernels and simulation via highorder vector autoregressive models
(Wichita State University, 201305)Vector autoregressive models have traditionally been used to model and forecast multivariate time series data, predicting future values based on previous observations. In this thesis, we introduce some multivariate time ... 
Status and latest results from MIPP
(Elsevier, 201212)We briefly review the need for high quality hadron production data. The Main Injector Particle Production experiment (MIPP) at Fermilab collected data in 2005/2006 and published final results on forward neutron production ... 
Steady axisymmetric vortex flows with swirl and shear
(Cambridge University Press, 20081001)A general procedure is presented for computing axisymmetric swirling vortices which are steady with respect to an inviscid flow that is either uniform at infinity or includes shear. We consider cases both with and without ... 
Steady axisymmetric vortex flows with swirl and shear
(Cambridge University Press, 200810)A general procedure is presented for computing axisymmetric swirling vortices which are steady with respect to an inviscid flow that is either uniform at infinity or includes shear. We consider cases both with and without ... 
Stellar modeling with lowtemperature onthefly opacity
(Wichita State University, 202105)Accurate stellar modeling requires using our understanding of phenomena far smaller than humans can observe to study some of the largest objects in the universe. One quantity that bridges this gap is the mean opacity, ... 
Stellar models of multiple populations in globular clusters  I. The main sequence of NGC 6752
(Oxford University Press, 20150111)We present stellar atmosphere and evolution models of mainsequence stars in two stellar populations of the Galactic globular cluster NGC 6752. These populations represent the two extremes of lightelement abundance ... 
Stochastic comparison for elliptically contoured random fields
(Elsevier, 20221001)This paper presents necessary and sufficient conditions for the peakedness comparison and convex ordering between two elliptically contoured random fields about their centers. A somewhat surprising finding is that the ... 
Stochastic monotonicity of a distribution family associated with matrix projections and its applications
(Wichita State University, 201912)This dissertation defines a distribution family based on the distribution of a random variable associated with the projections of a normally distributed random matrix with un known mean onto a linear space and onto a ... 
Stochastic representations of isotropic vector random fields on spheres
(Taylor & Francis Group, 2016)A stochastic representation is derived for a vector random field that is stationary, isotropic, and mean square continuous on a sphere or unit circle. The established stochastic representation is an infinite series involving ... 
Stress testing the vectorbosonfusion approximation in multijet final states
(American Physical Society, 20180822)We consider electroweak Higgs plus three jets production at NLO QCD beyond strict VBF acceptance cuts. We investigate, for the first time, how accurate the VBF approximation is in these regions and within perturbative ... 
Strict Whitney arcs and tquasi selfsimilar arcs
(Wichita State University, 201805)A connected compact subset E of RN is said to be a strict Whitney set if there exists a realvalued C1 function f on RN with ∇f E ≡ 0 such that f is constant on no nonempty relatively open subsets of E. We prove that ... 
Strong local nondeterminism and exact modulus of continuity for isotropic Gaussian random fields on compact twopoint homogeneous spaces
(Springer International Publishing, 20230103)This paper is concerned with sample path properties of realvalued isotropic Gaussian fields on compact twopoint homogeneous spaces. In particular, we establish the property of strong local nondeterminism of an isotropic ... 
Structural analysis and cations distribution of nanocrystalline Ni1xZnxFe1.7Ga0.3O4
(Elsevier B.V., 20140909)Nanostructured Ni1xZnxFe1.7Ga0.3O4, with x = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 were prepared by citrate method and were investigated using Xray diffraction and Mossbauer spectroscopy. The structure characterized using Xray ... 
Student's t vector random fields with powerlaw and loglaw decaying direct and cross covariances.
(Taylor & Francis, Inc, 20130101)This article deals with the Student's t vector random field, which is formulated as a scale mixture of Gaussian vector random fields, and whose finitedimensional distributions decay in powerlaw and have heavy tails. There ... 
Study of Morin transition in hematite (a Fe₂O₃) nanoparticles by Mössbauer spectroscopy
(Wichita State University, 202007)The change in magnetic properties of hematite (a Fe₂O₃) nanoparticles were investigated by observing the change of Morin transition fraction at different temperatures. Xray diffraction, transimission electron microscope ... 
A study of particular coordinate systems
(Wichita State University, 201105)This thesis is a study of the properties and relationships between isothermal, harmonic and characteristic coordinate systems. The proof of the existence of isothermal and characteristic coordinates on a manifold which ...
