Publication Interference Cancellation in Wideband Receivers using Compressed Sensing(2013-01-01) Peyyeti, Tejaswi CPrevious approach for narrowband interference cancellation based on compressed sensing (CS) in wideband receivers uses orthogonal projections to project away from the interference. This is not effective in the presence of nonlinear LNA (low noise amplifier) and finite bit ADCs (analog-to-digital converters) due to the fact that the nonidealities present will result in irresolvable intermodulation components and corrupt the signal reconstruction. Cancelling out the interferer before reaching the LNA thus becomes very important. A CS measurement matrix with randomly placed zeros in the frequency domain helps in this regard by removing the effect of interference when the signal measurements are performed before the LNA. Using this idea, under much idealized hardware assumptions impressive performance is obtained. The use of binary sequences which makes the hardware implementation simplistic is investigated in this thesis. Searching sequences with many spectral nulls turns out to be nontrivial. A theoretical approach for estimating probability of nulls is provided to reduce significant computational effort in the search and is shown to be close to actual search iterations. The use of real binary sequences (generated using ideal switches) obtained through the search does not do better compared to the orthogonal projection method in the presence of nonlinear LNA.Publication Analisis del Proceso de Adaptacion de Las Galas del Difunto de Valle-Inclan(2013-01-01) Maiztegui Zuazo, GorkaThe present research is focused on the formal devices that Azcona and José Luís García Sánchez display in the film adaptation of Las galas del difunto, a theater play included in Martes de Carnaval, published in 1930 by Ramón María del Valle-Inclán. Framed within the state politics of cultural promotion, Las galas del difunto was released for television consumption, thus, its characteristics are very relevant in order to analyze the priorities and strategies developed in the adaptation process. Not only does the main obstacle remain in the fact that the original play is difficult to represent in theater (mostly due to its secondary text), but also the metatextual dimension of Valle-Inclán’s texts. The Galician writer creates his own genre (el esperpento) trough both a series of characterization devices, a master use of language, and action structures; but also writing from a very particular perspective (looking for aesthetic distance) and mixing other existent genres. This complex collage crashes with the naturalistic tendency of audiovisual representation and offers a wide variety of open fronts that appeal directly to the adaptation concept. Clearly, the script writers have noticed the formal structures in the text and, to a certain extent, “translated” into genuine cinematographic language. However, the result of this sense of fidelity could present paradoxes within the movie and in regard to the audience’s reception. Those contradictions, even though included in the original play, have to deal with the whole new cinematographic context. The tensions between the play and the movie will arise through acting, lightning, camera framing, and mise en scene.Publication Response & Resistance: A Comparison of Middle Connecticut River Valley Ceramics from the Late Woodland Period to the Seventeeth-Century(2013-01-01) Woods, JulieNative Americans from the middle Connecticut River Valley of New England experienced massive social disruptions during the seventeenth century due to European settlement, but not much is known about their cultural continuities and/or discontinuities during this dynamic period. As an additive technology, ceramics embody the technical choices of potters made at the time of manufacture thus enabling the study of the effect, if any, of colonialism on indigenous material culture and practices in New England. This study examines ceramic assemblages from one Late Woodland period site and one seventeenth-century site in Deerfield, Massachusetts to explore the extent to which ceramics can demonstrate continuities and/or changes in traditional ceramic manufacturing practices in response and/or resistance to colonization.Publication Union Square(2013-01-01) Malone, Sarah KUnion Square is a novel set in and around the City of New York .Publication The Terrorist Doppelganger: Somoza and the Sandinistas(2013-01-01) Hohenstein, Thomas AThis thesis makes two arguments. First, that the analytical lens of terrorism is useful to understanding the modern state because it pits the state against its antithesis. Additionally, the discursive contest between the state and terrorists is best understood within a gendered framework. Second, the Sandinista Revolution did not revolutionize the discourse the Nicaraguan state used to legitimate itself, thus limiting the movement’s revolutionary nature.
