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 ...

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 ... 
Superconductivity and structural variation of the electroncorrelated layer systems Sr(Pd1xTx)(2)Ge2 (T = Co, Ni, Rh; 0 <= x <= 1)
(American Physical Society, 20120131)Superconductivity variations deduced from the xray diffraction and the magnetic and heatcapacity measurements in the pseudoternary Sr(Pd1xTx)(2)Ge2 layer system [Pd(4d(8)), T = Co(3d(7)), Ni(3d(8)), or Rh(4d(7)); 0 <= ... 
Superconvergence of discontinuous Galerkin method for linear hyperbolic equations
(Wichita State University, 202012)This thesis is concerned with the investigation of the superconvergence of the Discontinuous Method for linear conservation laws. We use Fourier analysis to study the superconvergence of the semidiscrete discontinuous ... 
Supernova neutrino burst detection with the deep underground neutrino experiment
(Springer Nature, 20210515)The Deep Underground Neutrino Experiment (DUNE), a 40kton underground liquid argon time projection chamber experiment, will be sensitive to the electronneutrino flavor component of the burst of neutrinos expected from ... 
Supernova neutrino detection in NOvA
(IOP Publishing Ltd, 20201005)The NOvA longbaseline neutrino experiment uses a pair of large, segmented, liquidscintillator calorimeters to study neutrino oscillations, using GeVscale neutrinos from the Fermilab NuMI beam. These detectors are also ... 
Synthesis of highly ordered 30 nm NiFe2O4 particles by the microwavecombustion method
(Elsevier B.V., 201411)NiFe2O4 of 30 nm average size was synthesized by microwave combustion and subsequent solid state reaction at 1273 K. The materials were characterized by Xray diffraction, TEM, vibrating sample magnetometery and Mossbauer ... 
Testing holomorphy on curves
(Springer, 201211)For a domain D aS, a"e (n) we construct a continuous foliation of D into onerealdimensional curves such that any function f a C (1)(D) which can be extended holomorphically into some neighborhood of each curve in the ... 
Testing homogeneity of a parameter matrix some of the rows of which are under synchronized order restrictions

Testing homogeneity of a parameter matrix with some rows constrained by synchronized order restrictions
(Wichita State University. Graduate School, 20100423)A multivariate linear regression model Y~N (βM',Σ) is considered where some of the rows in the coefficient matrix β are constrained by synchronized order restrictions. A test scheme is derived for the homogeneity of the ... 
The effect of small time delays on largescale systems
(Wichita State University, 201812)In this research, model reduction techniques are used to design optimal control strategies with low sensitivity in order to model uncertainty. The source of uncertainty encountered is the time delay, and the reducedorder ...
