Electrical & Computer Engineering Faculty Publications

Over the last few years several machine learning projects at Jefferson Lab have had a common focus to optimize operation of superconducting RF (SRF) cavities in the Continuous Electron Beam Accelerator Facility (CEBAF). In this talk we highlight work to identify and classify types of faults from C100-type cavities and then to extend those capabilities to provide real-time fault prediction. Early prediction may enable mitigation strategies to prevent some types of faults. In our approach we apply a two-step fault prediction pipeline. In the first step, a model distinguishes between faulty and normal signals. In the second step, signals flagged …

Intuitive Eating Behaviors Among A Sample Of Food Secure And Food Insecure College Students, Morgan Stocker, Christin Seher Phd, Rdn, Ld

Williams Honors College, Honors Research Projects

Intuitive Eating (IE) is a food mindset focusing on honoring hunger and fullness, while rejecting the diet mentality. Research demonstrates a clear link between IE and health outcomes across many populations, including college students. Despite a growing body of literature, we still know very little about what complexities food insecurity may present for individuals trying to adopt IE behaviors. This study builds off prior research to investigate IE behaviors in food insecure and food secure students through a Qualtrics survey utilizing the Intuitive Eating Scale-2 (IES-2) and the United States Department of Agriculture (USDA) Six-Item Short Form to determine food …

Functionalization Of Chitosan Based Microparticles For In Vitro 3d Culture Of Human Liver Cells, William Imes

Williams Honors College, Honors Research Projects

Previous work involving 3D culture of human liver cells with fluorinated chitosan based microparticles has shown that their incorporation provides needed structural cues that the culture of cells alone does not provide, such as increased gas transport. However, using bare microparticles to grow large 3D cellular structures is not practical as they tend to collapse before any meaningful research can be done on them. It is proposed that this is because of the lack of extracellular matrix (ECM)components within pure cell culture in vitro, which in their absence cannot adequately facilitate biochemical communication and adhesion between cells. It is …

Designing A Distillation Process For A Local Brewery, Julia Syme

Williams Honors College, Honors Research Projects

Proper distillation of spirits is key in maximizing resource value and producing a consumable liquid. A local brewery owner is considering entering the distilling market, and he requested information regarding a small-scale continuous column. This project used CHEMCAD to determine an operating design for continuous distillation of ethanol at a few different feed compositions. Since this model was limited to CHEMCAD, it had to build off of previous research and engineering parameters without an experimental verification. The project determined that an eight stage distillation column produced 40-58% ethanol product when the feed ranged from 7.5-12% ethanol. Eight stages produced even …
