Synthesis And Evaluation Of Long-Term History-Aware Medical Dialogue, Hebin Hu, Renke Dai, Ah-Hwee Tan, Yilin Kang

Research Collection School Of Computing and Information Systems

An effective healthcare agent must be able to recall and reason over a patient’s longitudinal medical history. However, the absence of datasets with realistic long-term dialogue timelines limits systematic evaluation. Real clinical text is constrained by privacy and ethics, while existing benchmarks focus on isolated interactions, failing to capture cross-session reasoning. We introduce a framework for synthesizing high-quality, long-term medical dialogues with LLMs. Our approach entails a knowledge-guided decomposition into three stages: constructing synthetic patient profiles with diverse disease and complication trajectories, generating multiturn dialogues per encounter, and integrating them into a coherent longitudinal history dataset, MediLongChat. We establish three …

Selective Concolic Testing, Guofeng Zhang, Zhenbang Chen, Ziqi Shuai, Jun Sun, Weijiang Hong, Yufeng Zhang, Ji Wang, Yang Liu

Research Collection School Of Computing and Information Systems

The principled combination of symbolic execution and random testing lacks a formal foundation, especially in deciding which inputs to symbolize. We propose selective concolic testing, a cost-aware framework that formulates this choice as an optimized policy problem of a MDP (Markov Decision Process). We model program exploration over a finite control-flow graph, where MDP states represent covered statements, actions partition path constraints into symbolic and random fragments, rewards reflect coverage gain, and costs account for SMT solving effort and sampling inefficiency. Our framework yields the first formal characterization of selective symbolization as policy synthesis in a probabilistic system. We prove …

Transform-Based Quantum Potential Reconstruction From Sparse Spectral Data: Generalized Bertlmann-Martin Moment Inequalities, Matthew Plott

Masters Theses and Doctoral Dissertations

Inverse quantum problems ask whether a central potential V(r) can be reconstructed from limited spectral information under explicit modeling assumptions. This dissertation develops and validates a reproducible, transform-based framework for reconstructing ground-state radial densities rho(r) = |R(r)|^2 and central potentials V(r) from discrete bound-state energy levels using generalized Bertlmann-Martin (GBM) moment inequalities as physics-informed constraints. In the Laplace route, L(q) is assembled from moment data and inverted numerically to recover rho(r). In the Fourier/form-factor route, even moments determine F(q) and inverse transformation yields rho(r). To support sparse spectral inputs, analytic continuation is performed with Pade approximants, and the framework is …

Exploring Dynamic Imine Bonds In Hemp-Seed Oil Based Reprocessable And Mechanically Robust Epoxy Vitrimer, Varshikkumar R. Patel

Electronic Theses & Dissertations

Epoxy thermosetting polymers are among the most versatile materials utilized across aerospace, automotive, construction, and electronic industries due to their exceptional mechanical strength, chemical inertness, and superior thermal stability. However, the majority of commercial epoxy resins are derived from non-renewable petroleum-based feedstocks such as bisphenol-A diglycidyl ether (DGEBA), which leads to inherent environmental challenges including non-biodegradability and the inability to be recycled or repaired after curing. These drawbacks arise primarily from the permanent covalent crosslinked architecture formed during the curing process, which prevents molecular mobility and reprocessability. To address these limitations, dynamic covalent chemistry (DCC) has emerged as a promising …

Extremum Seeking Compensation And Quantification Of Position Sensor Offset Error In Speed-Controlled Permanent Magnet Synchronous Motors, Tessa Biondo

Masters Theses

Position sensor offset errors present a persistent challenge in speed-controlled permanent magnet synchronous motor drives operating under field-oriented control. Even small, constant offsets in the measured rotor position can reduce torque effectiveness, requiring increased current and voltage demand to maintain the commanded speed and resulting in degraded speed regulation performance across a range of operating conditions. These effects are particularly problematic in speed-controlled systems, where speed loop dynamics cause increased electrical effort and limit overall performance. Many existing detection and compensation approaches are either dependent on the system model, require offline calibration, or are primarily designed for torque-controlled operation. This …

Architects, innovators, and the entire construction industry continue to push the newest, most expensive, high-tech solutions to problems that technology itself has caused. The broader public, however, seems to have little interest or support in investing in such endeavors. From Steel to Sanctuary presents a different solution, one with roots thousands of years in the making. Sustainable design is not a new way of thinking. Our ancestors had subsisted as active participants, rather than simply as a spectator to nature for millennia before the rise of the technological age. Today, we coin the strategies they employed as ‘passive’ architecture; Systems …

The Architecture Of Water Consciousness: Revealing Water, Culture, And Dwelling In Phoenix, Arizona, Luke Wendel

Architecture Theses

In the desert, water has always shaped how people dwell, build, gather, and survive. In Phoenix, Arizona, this relationship has become increasingly hidden behind canals, infrastructure, policy, and control. The river that once supported settlement is now often dry, and water is understood more as a managed resource than a visible presence in daily life. A reimagining is needed, as the future of desert cities depends not only on conserving water, but on changing how people experience and value it. Can architecture reveal water as something seen, felt, remembered, and shared? Located along the Rio Salado, this thesis proposes a …
