Deformations of Q-curvature II
(Springer, 2022-02-11)This is the second article of a sequence of research on deformations of Q-curvature. In the previous one, we studied local stability and rigidity phenomena of Q-curvature. 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, 2013-05)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 ProtoDUNE-SP liquid argon TPC
(IOP Publishing, 2022-01-04)The ProtoDUNE-SP detector is a single-phase 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., 2023-02-01)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 ... -
Development, thermal and dielectric investigations of $PVDF-Y_2O_3$ polymer nanocomposite films
(Springer, 2021-04-03)This work involves preparing $PVDF-Y_2O_3$ polymer nanocomposites to improve thermal and dielectric properties. X-ray diffraction, SEM, FTIR, TGA and dielectric measurements were applied for these films. The cubic crystal ... -
Effect of gallium additions on reduction, carburization and Fischer-Tropsch activity of iron catalysts
(Springer US, 2018-07)Undoped and gallium-doped iron oxide catalysts (100Fe, 100Fe:2Ga, and 100Fe:5Ga) were prepared by following a continuous co-precipitation technique using ammonium hydroxide as precipitant. The catalysts were characterized ... -
Effect of H2S in syngas on the Fischer-Tropsch synthesis performance of a precipitated iron catalyst
(Elsevier B.V., 2016-03-05)The sulfur limit, the relationship between the sulfur added and the surface Fe atoms lost (Fe/S), and mechanism of sulfur poisoning were studied using an iron Fischer-Tropsch synthesis (FTS) catalyst (100 Fe/5.1 Si/2.0Cu/3.0K). ... -
Effect of low-temperature opacities on stellar evolution
(Wichita State University, 2021-12)Stellar evolution is studied through computational models of stars since any perceived change in the stars can take thousands if not millions of years. One of the physical quantities that defines the evolution of a star ... -
Effect of support pretreatment temperature on the performance of an iron Fischer-Tropsch catalyst supported on silica-stabilized alumina
(MDPI, 2018-02-12)The effect of support material pretreatment temperature, prior to adding the active phase and promoters, on Fischer-Tropsch activity and selectivity was explored. Four iron catalysts were prepared on silica-stabilized ... -
The effects of individual metal contents on isochrones for C, N, O, Na, Mg, Al, Si, and Fe
(IOP Publishing, 2016-07-28)The individual characteristics of C, N, O, Na, Mg, Al, Si, and Fe on isochrones have been investigated in this study. Stellar models have been constructed for various mixtures in which the content of each element is changed ... -
Efficient calculation of Schwarz-Christoffel transformations for multiply connected domains using Laurent series
(Heldermann Verlag, 2013-08)We discuss recently developed numerics for the Schwarz–Christoffel transformation for unbounded multiply connected domains. The original infinite product representation for the derivative of the mapping function is replaced ... -
Eigenvalue estimates on Quaternion-Kähler manifolds
(Springer, 2023-01-09)We prove lower bound estimates for the first nonzero eigenvalue of the Laplacian on a compact quaternion-Kähler manifold. For the closed or Neumann case, the lower bounds depend on dimension, diameter, and lower bound of ... -
Elementary applications of matrices
(Wichita State University, 1948-07)This treatise is concerned principally with the fundamental properties of matrices, the basic operations which may be performed with them, and some of their applications to algebra, analytic geometry, and differential ... -
Elliptic Equations: Many Boundary Measurements
(Springer, 2017)We consider the Dirichlet problem (4.0.1), (4.0.2). At first we assume that for any Dirichlet data g0 we are given the Neumann data g1; in other words, we know the results of all possible boundary measurements, or the ... -
Elliptic equations: Single boundary measurements
(Springer, 2017)In this chapter we consider the elliptic second-order differential equation Au=finΩ,f=f0−∑j=1n∂jfjAu=finΩ,f=f0−∑j=1n∂jfj with the Dirichlet boundary data u=g0on∂Ω.u=g0on∂Ω. We assume that A = div(−a∇) + b ⋅ ∇ + c ... -
