The Baadasssss And The Avant-Garde: The Radical Aesthetics And Politics Of Melvin Van Peebles, Samuel Jay Smucker

Theses

Melvin Van Peebles is best known for Sweet Sweetback’s Baadasssss Song (1971) and that film’s role in inspiring the Blaxploitation cycle of films of the early 1970s. However, it was in France, where he had emigrated like other black creatives in the 1960s, that Van Peebles became a filmmaker. Drawing on biographical research and a close reading of his films, I connect Van Peebles to the institutions and aesthetics of the French New Wave. Van Peebles radicalizes New Wave techniques by employing them to illuminate issues of racism. I generate a new reading of Sweetback which connects the experimental aesthetics …

Habitat And Conservation Suitability Assessment For Shrubland Birds In Monroe County, New York, Rachel Allen

Theses

Shrublands and successional ecosystems are of special interest to land managers and conservation groups because to be maintained, they must be disturbed periodically. Shrubland birds rely on variation in the landscape, regular disturbance, and ephemeral patches of shrubs for breeding, foraging, and nesting. Many of these avian species are in decline, so monitoring and mapping shrublands is necessary for future conservation and management strategies (DeGraaf & Yamasaki, 2003; Howard et al., 2015; Litvaitis, 2003). Large proportions of shrubland bird populations rely on shrublands in the northeast states for breeding habitat, and the identification and land use monitoring of these regions …

An Empirical Study On Discovering A New Self-Admitted Technical Debt Type - Api-Debt, Ahmed Aljohani

Theses

Self-Admitted Technical Debt (SATD) is when developers intentionally choose to take short-cuts, non-optimal solutions (e.g. temporary fix or rush code development) that negatively contribute to long-term source-code quality in order to achieve short-term goals such as product deadline. Several studies have successfully identified SATD through the source-comments, classified them into five types (design debt, defect debt, documentation debt, requirement debt, and test debt) based on how they negatively affect different parts of the source-code and proposed a tool that automatically detects SATD using the source comments as input. However, few papers deeply investigate the types of SATD and their effects …

Analog Musical Distortion Circuits For Electric Guitars, Timothy Douglas Sunnerberg

Theses

Distortion, while seen as undesirable in most contexts, has taken a different role in electronic music. Musical distortion refers to nonlinear changes in a waveform, and has been used to change the sounds of electric guitars since the 1940s and 1950s. Originally, distortion was realized with broken tubes in amplifiers or torn speaker cones, but as music evolved, so did the equipment used to produce the desired sounds. Slashed speakers turned into electronic circuits in the mid 1960s, and these electronic circuits are the focus of this paper. Many papers discuss the digitization of analog circuits, but because most analog …

Investigation Of The Benefits Of Interlocked Synchronous Pipelines, Sabrina Rose Levitan

Theses

The majority of today’s digital circuits use synchronous pipelines. As the technology nodes get smaller, these pipelines are facing problems with area, power, and timing. One of the major sources of power consumption is the global clock and stall signals. These signals have to be routed across large sections of the chip, and with regards to stalling the pipeline, often face significant timing issues. One solution, developed by Hans M. Jacobson et al., is “Synchronous Interlocked Pipelines”. This pipeline design combines synchronous pipelines with the handshaking of asynchronous pipelines. Asynchronous pipelines are less power intensive because they send acknowledge and …

Efficient Distribution Regression, Nicholas Wilkins

Theses

In this thesis we devise a method for performing distribution regression utilizing an extension of mixture density networks. This method will be benchmarked against other state-of-the-art methods (utilizing negative log loss) and distribution-agnostic models of similar complexity. We demonstrate that our proposed method performs at least as well as the state-of-the-art methods in distribution regression. Additionally, we show that adding distribution predictive capabilities does not significantly decrease performance in models. We illustrate how one can utilize this methodology to regress to confidence interval predictions. Finally, we demonstrate a variety of novel and interesting applications of our framework.

Design Of A Flexible Schoenhage-Strassen Fft Polynomial Multiplier With High-Level Synthesis, Kevin Millar

Theses

Homomorphic Encryption (HE) is a promising field because it allows for encrypted data to be sent to and operated on by untrusted parties without the risk of privacy compromise. The benefits and applications of HE are far reaching, especially in regard to cloud computing. However, current HE solutions require resource intensive arithmetic operations such as high precision, high degree polynomial multiplication resulting in a minimum computational complexity of O(n log(n)) on standard CPUs though application of the Fast Fourier Transform (FFT). These operations result in poor overall performance for HE schemes in software and would benefit greatly from hardware acceleration. …

Environmental Risks And Benefits Of Nano-Enabled Clean Energy Technologies, Elizabeth A. Moore

Theses

Engineered nanomaterials (ENMs) are increasingly incorporated into clean energy technologies due to observed improvement in technological and system performance. Though these materials could revolutionize many products and technologies, increased use of ENMs can also introduce uncertainty and risks that are difficult to predict. Increase in ENM use could significantly increase ENM releases to the environment across their life cycle, from material synthesis to end-of-life. To address knowledge gaps and uncertainties, this work assesses a portfolio of ENMs from a systems perspective.
