Physiology Faculty Publications

Introduction: Cold-induced vasodilation (CIVD) is a counterintuitive focal increase in glabrous skin blood flow during cold exposure with unclear local and neural mechanisms. Methods: We tested 12 (8 men, 4 women) healthy subjects’ laser-Doppler flux (LDF; just proximal to the nailbed) and arterial blood pressure (ABP) on a beat-by-beat basis. The experimental hand was exposed to warm (10 min 35°C) and then cold (30 min 8°C) water immersion and the contralateral control hand experienced 22°C–23°C air throughout. We analyzed beat-by-beat oscillations in LDF and ABP via a fast-Fourier transform (FFT) and transfer function analysis (TFA) of LDF to ABP. Results: …

To Be Loved Is To Be Seen: Gazing As A Form Of Interpretation In The Turn Of The Screw, Yasmin Mezayek

Theses and Dissertations

The heated discourse that would follow Henry James’s novella “The Turn of the Screw” centered on whether the ghosts were real or not. With Shoshana Felman’s groundbreaking article “Turning the Screw of Interpretation” a new-found focus on the ambiguities, as opposed to finding a singular, definitive meaning of the novella would usurp the Freudian and anti-Freudian arguments. With the governess’s sight being the main source of debate, reading the novella through the Lacanian lens of the Gaze, the Imaginary, and the Symbolic offer unprecedented explanations and arguments for the governess’s behavior. Given the contemporary shift to discussing the ambiguities of …

Online Parameter Adaptation Of Lqr Controllers Via Rls For Prosthetic Joint Control: Experimental Validation On A Quanser Qube-Servo 2 Platform, Cynthia Lopez-Jordan

Theses and Dissertations

This thesis develops and experimentally validates an online adaptive Linear Quadratic Regulator (LQR) control method for prosthetic joint systems using Recursive Least Squares (RLS)-based real-time parameter estimation on the Quanser QUBE-Servo 2 platform. Traditional LQR controllers assume a fxed system model, which limits adaptability and results in reduced tracking accuracy, poor robustness, and loss of optimal performance when applied to dynamically changing prosthetic joints, infuenced by load variations, user gait changes, and mechanical wear. Limited experimental validation exists for combining RLS with online LQR adaptation in prosthetic-like systems.

To address these limitations, an RLS-driven Adaptive LQR framework was implemented to …

This thesis presents the design and control of a low-cost stroke therapy device designed to promote upper …

“Democracy,” Usa, Marc Edelman

Publications and Research

What does it mean to be an effective citizen in a democracy? Answering this question requires unpacking “democracy” and an analysis of institutions that systematically disempower and alienate citizens. This paper briefly examines the contributions of psychoanalysis to understanding democracy and authoritarianism. It scrutinizes U.S. governance institutions and points to democratic deficits and backsliding present even before Trump 1.0 and 2.0. These range from the Electoral College, the Senate, and the Supreme Court to the Federal Communications Commission. All contributed to institutionalizing minority rule and elite capture. Governance institutions failed to deliver what the American people tell opinion pollsters they …

Toward A Combine-Style Approach To Predicting Future Esports Success, Nicholas David Bowman, Kevin Sweeney, Aaron R. Seitz, C. Shawn Green

Media Studies - Open-Access Faculty Scholarship

Historically, there has been a great deal of interest in using basicmeasures of individual difference factors to predict future success in traditional sports. For instance, the National Football League (NFL) holds a scouting combine each year prior to the NFL draft during which a host of attributes about players are measured, from basic height and weight, to sprint speed, to jumping capacity, to strength. Even among an already highly selected group of individuals (i.e., individuals skilled enough to even be considered for the NFL), such measures have been seen to have some degree of utility in predicting future performance.

Improved Performance Of Catalysts Containing Pt, Pt-Sn, And V In The Dehydrogenation Of N-Butane By Radio-Frequency Induction Heating, Cameron L. Roman, Jonathan Lucas, James A. Dorman, Kerry M. Dooley

Faculty Publications

Due to an abundance of shale gas, manufacturers are interested in meeting increased demands for alkenes, especially n-alkenes, by the dehydrogenation of light alkanes. While the catalysts for these reactions have been studied for many years, alkene selectivity and deactivation remain challenging problems. This work addresses these problems by the substitution of a localized indirect heating method (radio-frequency induction heating, RF-IH) for more traditional process heating employing steam or burners (e.g., natural gas combustion). RF-IH has been applied to the dehydrogenation of n-butane to C4 alkenes by utilizing magnetically susceptible catalysts based on Fe/Fe3O4 susceptors. Magnetic core-shell catalysts with either …

Poromechanical Solution For One-Dimensional Large Strain Consolidation Of Modified Cam-Clay Soil, Sheng Li Chen, Hai Sui Yu, Younane N. Abousleiman, Christopher E. Kees

Faculty Publications

A theoretical model describing the one-dimensional large strain consolidation of the modified Cam-Clay soil is presented in this paper. The model is based on the Lagrangian formulation and is capable of featuring the variability of soil compressibility (inherently due to the direct incorporation of the specific Cam-Clay plasticity model) and permeability, as well as the impact of the overconsolidation ratio (OCR). The derivation starts from the establishment of the incremental stress–strain relations for both purely elastic and elastoplastic deformations under one-dimensional compression conditions, and thereafter the coefficients of compressibility/volume change that are essential to the consolidation analysis. The governing partial …

Death And Inheritance: How Meanings Of Money Are Drawn From Everyday Life, Kendall Coney

Sociology Honors Projects

Probate is a legal process to distribute a deceased person’s assets involving a personal representative who administers the estate on behalf of the deceased. It is uniquely situated in the intersection of a procedurally exhaustive process and the deeply emotional experience of losing a loved one, where legal procedures are imposed on relational contexts. I draw on in-depth interviews with personal representatives from four counties in Minnesota to expose the dissimilar way personal representatives understand the meaning of inheritance money, which in turn influenced how they understood and navigated the probate process. The lack of a clear pattern found in …

Risk-Averse And Multi-Objective Decision-Making Models For Rehabilitating Water Pipeline Networks Subjected To Earthquakes, Sumaya Sharveen

Civil Engineering Dissertations - Archive

Water distribution networks (WDNs) are critical infrastructure systems that are highly vulnerable to seismic hazards. Utility managers are often required to make proactive rehabilitation decisions under uncertainty, constrained by limited resources. However, existing seismic rehabilitation decision-making models typically ignore the influence of risk preferences, assume cooperation among conflicting objectives, and lack flexibility in addressing the diverse needs of utilities. This research aims to develop comprehensive risk-averse and multi-objective decision-making models to identify critical pipelines for proactive seismic rehabilitation in WDNs. Three distinct models are proposed to support utility decision-making across different planning contexts. First, a single-objective risk-averse simulated annealing (RSA) …
