Time Integration Methods Of Fundamental Solutions And Approximate Fundamental Solutions For Nonlinear Elliptic Partial Differential Equations, Corey Leon Jones

Dissertations

A time-dependent method is coupled with the Method of Approximate Particular Solutions (MAPS) of Delta-shaped basis functions, the Method of Fundamental Solutions (MFS), and the Method of Approximate Fundamental Solutions (MAFS) to solve a second order nonlinear elliptic partial differential equation (PDE) on regular and irregular shaped domains. The nonlinear PDE boundary value problem is first transformed into a time-dependent quasilinear problem by introducing a fictitious time. Forward Euler integration is then used to ultimately convert the problem into a sequence of time-dependent linear nonhomogeneous modified Helmholtz boundary value problems on which the superposition principle is applied to split the …

Harlem In Shakespeare And Shakespeare In Harlem: The Sonnets Of Claude Mckay, Countee Cullen, Langston Hughes, And Gwendolyn Brooks, David J. Leitner

Dissertations

This study responds to the need for an understanding of the relation of form and political critique within the sonnet form, and hopes to demonstrate that the sonnet can be used to effectively articulate the experience of racism, especially the Du Boisian concept of "double- consciousness," a sense of two-ness born of being both black and American. The fundamental structure of the sonnet (octave, volta, sestet) is dialectical; it "contests the idea it just introduced" (Caplan, Poetic Form: An Introduction 75). The sonnet's self-reflexive structure has been adopted and adapted by poets such as McKay, Cullen, Hughes, and Brooks. The …

The Effect Of Racial Status And Other Core Characteristics On Collective Self-Esteem A Quantitative Test Of Divergent Theories Of Identity Valuation, Wilfred Reilly

Dissertations

The question of why individuals value identities like race and gender is a contested one. Scholars in the Reflected Appraisals tradition argue that members of minority groups experience identity devaluation and minority stress (Hacker 1992; Harris 1993; Meyer 1995; Tatum 1997; Hoff-Sommers 2000; McIntyre 2002) and come to value their identities less in empirical terms than do members of equivalent majority groups (Harris 1993; Hacker 1995). The thesis here is that the values individuals place upon in-group identities are determined by the prestige and power of their in-groups (Cornell and Hartmann 2006: 60). This argument has been advanced often in …

Wavelet Analysis Of Non-Stationary Signals With Applications, Maria Dorothea Van Der Walt

Dissertations

The empirical mode decomposition (EMD) algorithm, introduced by N.E. Huang et al in 1998, is arguably the most popular mathematical scheme for non-stationary signal decomposition and analysis. The objective of EMD is to separate a given signal into a number of components, called intrinsic mode functions (IMF's), after which the instantaneous frequency (IF) and amplitude of each IMF are computed through Hilbert spectral analysis (HSA). On the other hand, the synchrosqueezed wavelet transform (SST), introduced by I. Daubechies and S. Maes in 1996 and further developed by I. Daubechies, J. Lu and H.-T. Wu in 2011, is first applied to …
