Understanding And Defending Large-Scale Networked Systems: From Wi-Fi Localization To Provenance- Based Intrusion Detection, Xiao Han

USF Tampa Graduate Theses and Dissertations

Modern networked systems increasingly depend on wireless sensing and large-scale telemetry to provide critical services and maintain security. However, many of these systems function as black boxes or encounter significant scalability limitations, which leave them vulnerable to sophisticated adversaries. In this dissertation, I present my research on enhancing the security and efficiency of networked systems through measurement-driven vulnerability analysis and the design of scalable defense mechanisms.

First, I present my research on the security and privacy risks of Wi-Fi–based localization services. Although location spoofing attacks against Wi-Fi positioning systems have been studied for over a decade, constructing practical attacks in …

Mismatched Music And Meams: Short-Form Social Media Videos And Social Attitude Messaging, Kaitlyn M. Serafin

USF Tampa Graduate Theses and Dissertations

“If the formative power in the media are the media themselves, that raises a host of large matters” (McLuhan, 1964, p. 10). Famed communications theorist Marshall McLuhan stated this all the way back in the 60s to explain how technology can act as a formative force in the messaging of media. This is because the medium in which they communicate the messaging can act as its own force, shaping the message like clay. The dominant media at the time of this theory was television; however, in the past decade social media and short-form social media videos have become dominant forms …

Spin Pumping And Interfacial Anisotropy In Ultrathin Cobalt Heterostructures, Ibrahim Almuhanna

USF Tampa Graduate Theses and Dissertations

Interfaces dominate the behavior of ultrathin ferromagnets, where interfacial spin-orbit coupling(SOC) can strongly influence both magnetic anisotropy and magnetization dynamics. This thesis compares how a heavy-metal interface (Pt) and a semiconducting two-dimensional transition-metal dichalcogenide (TMD) interface (MoSe2) modify the static and dynamic magnetic properties of ultrathin Co. To isolate interface-driven effects, the heterostructure architecture is kept fixed (sapphire substrate and Si3N4 cap) while only the seeding/interface layer beneath Co is varied. MoSe2 is studied in two thickness conditions (monolayer and bilayer) to test layer-dependent trends.

Layer thicknesses are determined by X-ray reflectivity. Static magnetic properties are measured by in-plane vibrating …

Quantification Of Interfacial Defects In Frp-Strengthened Rc Member Using Non-Destructive Testing Methods, Yuliya Tyrak

USF Tampa Graduate Theses and Dissertations

Externally bonded fiber-reinforced polymer (FRP) composites are widely used to strengthen reinforced concrete (RC) structures. However, the long-term performance of these systems depends on the integrity of the FRP–concrete bond. Interfacial defects such as debonding, delamination, cracking, and voids may reduce structural capacity and are often difficult to detect using conventional inspection techniques. This study investigates the effectiveness of nondestructive testing (NDT) methods for detecting interfacial defects in FRP-strengthened RC members. It explores the potential for automated defect identification using thermal imaging and machine learning.

Laboratory specimens with predefined defects were fabricated and tested using visual inspection (VI), tap testing …

The Development And Validation Of A Portable Monitoring System For Real-World Prosthetic And Orthotic Performance Assessment, Emily Wyatt

USF Tampa Graduate Theses and Dissertations

Laboratory-based motion capture systems are widely used for gait analysis but are limited by high cost, infrastructure requirements, and restricted external validity. Inertial measurement units (IMUs) offer a portable and low-cost alternative for assessing gait in both controlled and real-world environments; however, their accuracy and clinical utility require validation. The purpose of this thesis was to develop and evaluate a portable monitoring system using IMUs to quantify spatiotemporal gait parameters and gait asymmetry in both laboratory and community settings, with a focus on prosthetic and orthotic users.

Phase 1 of this study evaluated the agreement between IMU-derived gait metrics and …

Dual-Modal Tumor Imaging Using Functionalized Iron-Oxide Nanoparticles For Mri And Fluorescence, Kevin Secades

USF Tampa Graduate Theses and Dissertations

Accurate tumor imaging is essential for early cancer detection and treatment monitoring [1]. Technetium-99m (Tc-99m) is a commonly used radioisotope for medical imaging, but its reliance on gamma-ray emission poses challenges related to safety, accessibility, and regulatory constraints[2-5]. This research proposes the development of a dual-modal imaging approach by functionalizing iron-oxide nanoparticles (IONPs) with the fluorescent chromophore Cy5, enabling both MRI contrast enhancement and optical imaging for improved tumor specificity. IONPs provide strong T2-weighted MRI contrast [6], while conjugated near-infrared (NIR) chromophores allow for high-resolution fluorescence imaging [7], making this proposed system adaptable for both in vitro and in vivo …

Analysis Of The Yeast Surface Display Platform As A Tool For Tyrosine Kinase Phosphorylation Assays, Alexandra Maritza Tang

USF Tampa Graduate Theses and Dissertations

Developing and optimizing platforms to study complex protein-protein interactions is important to maintain fidelity of the modeled activity. Yeast surface display has been used as a high-throughput platform to model substrate phosphorylation by tyrosine kinases, a key enzymatic process that is essential for most cell signaling pathways. However, existing characteristics of the yeast surface display platform limit the ease-of-use, reproducibility, and feasibility of screening enzymatic modification processes like tyrosine phosphorylation. The cytoplasmic domain of T cell costimulatory receptor CD28 and lymphocyte kinase (LCK) were used as a model enzyme-substrate pair to showcase molecular cloning issues that can hinder reproducibility and …

They Find A Way: The Transnational Practices And Experiences Of Diaspora Conflict Journalists, Grace E. Smith

USF Tampa Graduate Theses and Dissertations

As global tensions continue to rise, media landscapes are changing. Diaspora communities play an integral role in this shift, as they search for verifiable news with a global perspective to keep them informed on crises in their home countries. In order to keep their communities informed, diaspora journalists step up to localize coverage, creating transnational networks to bridge home and host countries. They often work through intense situations, sacrificing normalcy for information. Building on the framework from Ogunyemi’s (2018) diasporic media observations, Fraser’s (1992) counterpublics theory, and D.K. Thussu’s (2006) contra-flow in global media theory, this study explores how diaspora …

Numerals And Other Means Of Expressing Plurality In Language And Thought: A Developmental Perspective Across Cultures., Giovanni Giuseppe G.G. Nicosia Prof.

Numeracy

Several ancient languages use linguistic structures to differentiate between singular, dual, and plural forms that are used when one, two, or many objects are referenced. (Some languages go further, adding a trial form to differentiate two from three.) In many modern languages, numerals are used to convey precise number. After reviewing a range of ways languages express number (including the interesting case of Pirahã which does not express precise number), the paper concludes with a proposed developmental path for the expression of quantity in languages.

Targeting Cancer With T Cells: Preclinical And In Silico Insights To Improve Immunotherapies, Nina Obertopp

USF Tampa Graduate Theses and Dissertations

T-cell–based immunotherapies are often constrained by limited trafficking and persistence in tumors and by functional exhaustion under chronic antigen exposure. This dissertation addresses these barriers through two distinct strategies: (i) preclinical studies testing how radiation therapy modulates tumor-infiltrating lymphocytes (TIL) therapy, and (ii) agent based modeling (ABM) to optimize treatment day treatment-free intervals (TFI) in T-cell engager (TCE) therapy. (i) In a human papillomavirus–positive (HPV⁺) head-and-neck cancer (HNC) model, a single local-dose of RT (8 Gy) delivered five days before tumor harvest increased the success and functional quality of ex vivo TIL outgrowth from tumor fragments, enriching polyfunctional CD8⁺ subsets. …

Sensi-Train: Context-Aware Sensitive Content Detection Using Transformers And Large Language Models, Nazeefa Muzammil

USF Tampa Graduate Theses and Dissertations

The detection of sensitive content has become a critical task in natural language processing due to the widespread use of online platforms and the social harm caused by it. Even though current methods have advanced significantly, many of them mainly rely on surface-level text and neglect to take into consideration contextual and cultural elements that are crucial for correctly assessing sensitivity of any content to a particular individual. Due to this, implicit offense, sarcasm, and culturally grounded expressions frequently cause problems for such systems. To enable culturally grounded sensitive content detection, this thesis presents Sensi-Train, a context-rich dataset and modeling …
