A Review Of Random Matrix Theory With An Application To Biological Data, Jesse Aaron Marks

Masters Theses

"Random matrix theory (RMT) is an area of study that has applications in a wide variety of scientific disciplines. The foundation of RMT is based on the analysis of the eigenvalue behavior of matrices. The eigenvalues of a random matrix (a matrix with stochastic entries) will behave differently than the eigenvalues from a matrix with non-random properties. Studying this bifurcation of the eigenvalue behavior provides the means to which system-specific signals can be distinguished from randomness. In particular, RMT provides an algorithmic approach to objectively remove noise from matrices with embedded signals.

Major advances in data acquisition capabilities have changed …

On Solid Ground I Stand: Narratives On Disclosure, Resilience, And Faith Amidst Recognition Of Childhood Sexual Abuse, Wade Rhodes Dundee

Masters Theses

Childhood sexual abuse seems to be a hidden secret in American society; one of the famous, "If we don't talk about it, it won't happen" narratives. However, we know this is not true. Both the National Sexual Violence Resource Center (2012) and Center for Disease Control and Prevention (2005) state one in four girls and one in six boys will fall victim to sexual abuse before they celebrate their 18th birthday. There is a high probability that because of the alarming lack of disclosure of male survivors, these statistics could be incorrect and could hinder creating or allowing for conversations …

Wrinkling Of Functionally Graded Sandwich Structures Subject To Biaxial And In-Plane Shear Loads, Harold Costa

Masters Theses

"Benefits of a functionally graded core increasing wrinkling stability of sandwich panels have been demonstrated in a recent paper [1] where a several-fold increase in the wrinkling stress was observed, without a significant weight penalty, using a stiffer core adjacent to the facings. In the present paper wrinkling is analyzed in case where the facings are subject to biaxial compression and/or in-plane shear loading and the core is arbitrary graded through-the-thickness. Two issues addressed are the effect of biaxial or in-plane shear loads on wrinkling stability of panels with both graded and ungraded core and the verification that functional grading …

Assessment Of Rockfall Rollout Risk Along Varying Slope Geometries Using The Rocfall And Crsp Software, Mariam S. Al E'Bayat

The Power Of The Periphery: Aid, Mutuality And Cold War U.S-Ghana Relations, 1957-1966, Moses Allor Awinsong

Masters Theses

This project interrogates how economic self interest motivated periphery states such as Ghana to use foreign policy as a vehicle to attract improved development assistance from superpowers, in this case the United States. While the United States viewed its aid program in Ghana in stringently Cold War terms, Kwame Nkrumah and his advisors were less inclined to get deeply concerned about Cold War ideology. This project shows that Ghanaian agency was manifested in the Cold War through the new state's construction of a foreign policy image that made it a prominent African voice globally. It then examines how that image …
