The Nature Of Things: An Investigation Into A Viking Age Assembly Site, Tyler L. Perkins

Graduate Masters Theses

Icelandic sagas and archaeological research suggest that Viking Age Icelandic assembly sites or things (þing) were generally occupied for brief periods of time during annual gatherings. One of the archaeological manifestations of repeated temporary occupation around assembly sites is small booths. At Hegranesþing in North Iceland, besides multiple booths that cover the site, there is also evidence of long-term occupation and farming. The Skagafjörður Church and Settlement Survey conducted geophysical and coring surveys, excavated three test pits into middens from different periods of occupation, and excavated one test trench into the homefield enclosure (tún) wall. The results suggest Hegranesþing, besides …

A Bostonian In Cuba: Edwin F. Atkins And United States Imperialism In Latin America, Miles Klotz

This thesis examines the attitudes and …

As Sacred As The Laws Of God: Property As The Link Between Cicero, Jefferson And Adams, Adam Mattison

Graduate Masters Theses

Gilbert Chinard’s publication of Thomas Jefferson’s legal commonplace book in 1926 and literary commonplace book in 1928 introduced a new question into the study of the American Founders: what was the relationship between the Founders and the authors of the classical world? Through the twentieth century, the historiography of that question has resolved into three separate streams represented by Bernard Bailyn’s Ideological Origins of the American Revolution, Meyer Reinhold’s Classica Americana and Carl Richard’s The Founders and the Classics. These three scholars argued respectively; that the Founders were not influenced by the classics and only used them as ornamentation …

Through the successful synthesis of viscoelastically ”degenerate” samples, the study utilizes an array of characterization techniques including frequency sweeps, Large Amplitude Oscillatory Shear (LAOS) to resolve these unique underlying states. Furthermore, the work explores further avenues of study …

The Sliding Aperture Transform: A Mathematical Method Applied To Radiation-Induced Dlts Capacitance Transients, Md Abu Bakkar Siddique

Graduate Masters Theses

This thesis presents the Sliding Aperture Transform (SLAPt), a novel mathematical technique for extracting exponential argument and pre-factor  from experimental data. The method transforms measured waveforms into an inverse-domain representation where exponential decay processes appear as distinct peaks, simplifying data analysis and reducing the effects of baseline offsets and noise. The technique is here applied to time dependent capacitance transients associated with irradiated and non-irradiated silicon pn junction diodes. The technique is further developed and applied to positive argument exponentials using an axillary function. This allows forward bias  current-voltage measurements, and forward pulse-bias current transient measurements to be SLAP analyzed, …

Beyond A Little Italy: Italian Community Formation In Washington, D.C., Kathleen P C Millander

Graduate Masters Theses

This thesis examines the development of the Italian immigrant community in Washington, DC, from the early nineteenth century through the beginning of the Second World War. Unlike the dense ethnic enclaves that characterized Italian settlement in many American industrial and port cities, Washington never developed a recognizable Little Italy. Nevertheless, Italians in the nation's capital constructed a cohesive community through social, religious, familial, and economic networks that connected a geographically dispersed population.
