Scalable Hybrid Neuromorphic Accelerator & Hybrid Neural Networks, Joshua Nardone

Master's Theses

With machine learning workloads currently at very large scales, models are distributed across large compute systems. On distributed systems, the performance of these models are limited by the bandwidth limitations of chip-to-chip communication. To relieve this bottleneck, spiking neural networks (SNNs) can be utilized to reduce inter-chip communication traffic utilizing inherit network sparsity. However, in comparison to traditional artificial neural networks (ANNs), SNNs can have significant degradation in performance with increased network scale and complexity.

This research proposes a hybrid neural network accelerator that uses the best of both spiking and non-spiking layers by allocating a majority of resources to …

An Evaluation Of Sonderegger Pine Morphology, Kelsey Denise Shoemaker

Master's Theses

Sonderegger pine (Pinus x sondereggeri H.H. Chapm.), the naturally occurring hybrid of longleaf (Pinus palustris Mill.) and loblolly pine (Pinus taeda L.), is considered a producer of poor-quality wood due to observations of stem forking and a high number of large-diameter branches at maturity. Because landowners generally decline planting Sonderegger pine seedlings, nursery workers cull putative hybrids from longleaf pine seedling stock during lifting and processing. However, over the past 100 years, very few studies have quantified stem quality of Sonderegger pine. To gain a better understanding of the early growth and development of Sonderegger pine, evaluations of height, diameter …

Effect Of Sex On The Accumulation Of Hepatic Mercury In Mallards Wintering In Louisiana, Latorya E. Mason

Master's Theses

The increase in mercury production through anthropogenic activities has led to a global crisis of mercury pollution that poses a significant threat to the health of both humans and wildlife. Aquatic ecosystems are especially at risk due to the creation of methylmercury, a toxic form of mercury, by sulfate-reducing bacteria in anoxic sediments and soils. Methylmercury enters the food chain where it bioaccumulates in individual organisms and then biomagnified with increasing trophic level. Aquatic birds are useful bioindicators of many pollutants, including mercury, due to their abundance and position in the food chain. Previous studies have primarily focused on mercury …
