Perturbation Based Decomposition For Motor Unit Number Estimation, Anna T. Pham

Master's Theses

Motor unit number estimation (MUNE) is of clinical significance because information associated with motor unit populations and the loss of motor units over time are crucial to the diagnosis and monitoring of neuromuscular disorders. The responses of individual motor units can be extracted through incremental stimulation of a muscle group of interest and further analyzed through various methods to compute the MUNE. In this work, the utility of the perturbation-based decomposition by Szlavik will be investigated for this application and compared to the original MUNE approach developed by McComas. Successful decomposition may suggest an alternative method for motor unit number …

Decentralized Machine Learning On Blockchain: Developing A Federated Learning Based System, Nikhil Sridhar

Master's Theses

Traditional Machine Learning (ML) methods usually rely on a central server to per-
form ML tasks. However, these methods have problems like security risks, data
storage issues, and high computational demands. Federated Learning (FL), on the
other hand, spreads out the ML process. It trains models on local devices and then
combines them centrally. While FL improves computing and customization, it still
faces the same challenges as centralized ML in security and data storage.

This thesis introduces a new approach combining Federated Learning and Decen-
tralized Machine Learning (DML), which operates on an Ethereum Virtual Machine
(EVM) compatible blockchain. The …

Characterizing The Utility Of A Near Infrared Click Beetle Luciferase For Bli Applications, Giovanni Duca

Master's Theses

Bioluminescent imaging systems (BLI) have become a valuable tool for doing real-time in vivo studies. BLI systems typically allow for the imaging of surface and subsurface level tissues but as depth increases, the resolution decreases while the signal to noise ratio increases. Deep tissue imaging is therefore a major limitation for BLI. To address this limitation there has been a consistent movement in luciferase research to create long wavelength emitting luciferases that still have a high photon emission rate. Longer wavelengths of light are able to penetrate deeper tissues due to having a lower amount of absorbance and scattering from …
