Resilient Learning For Anomaly Detection In Smart Living Systems, Sahar Abedzadeh

Dissertations

Cyber-Physical Systems (CPS) rely on anomaly-based detection methods to ensure the integrity and security of critical infrastructures such as smart grids, smart water metering systems, and advanced metering infrastructures (AMI). Anomaly detection methods are commonly used to identify deviations from normal system behavior by establishing learned profiles and thresholdbased distinctions between benign and anomalous events. However, conventional frameworks often fail to account for adversarial data poisoning attacks, unlabeled unsafe events, and environmental noise—factors that distort training data, degrade detection accuracy, and increase false alarms. This dissertation proposes a resilient learning framework that mitigates these biases by integrating quantile regression, M-estimation …

Utilizing Drainage Induced Pfas Enrichment In Cascade Generated Foam For Efficient Removal At Wastewater Treatment Plants, Ethan Samuel Coffin

Dissertations

Observed trends in municipal solid waste landfills reveal a distinct disparity between per- and polyfluorinated alkyl substances (PFAS) composition entering in waste, mostly as diPAP and FTOH, and leaching out as FTCA and PFCA. These patterns are elucidated by compiling PFAS compositions in paper, textiles, and carpet, with known precursor transformations that generate FTCA and PFCA in leachate. Landfill leachate is commonly discharged to wastewater treatment plants (WWTP), which are ineffective at degrading PFAS and only serve as key conduits and discharge points for PFAS to the environment.

Investigating The Proviral And Immunogenic Effects Of Sars-Cov-2 Accessory Protein 7a, Grant Michael Hawkins

Dissertations

SARS-CoV-2 and related sarbecoviruses encode a set of accessory proteins (3a, 3b, 6, 7a, 7b, 8, 9b, and 10) that control host responses to infection and promote virus growth. Of these accessory proteins, 7a is set apart by its intracellular localization near coronavirus (CoV) budding sites and its incorporation into secreted virions. Initial studies utilizing a virus-like particle (VLP) system identified significant proviral effects mediated by 7a, but the system lacked the context of an actual CoV infection. To investigate 7a functions during CoV infections, we constructed recombinant Mouse Hepatitis Viruses (rMHV strain A59) that express 7a genes. Comparative infections …
