Knee Angles After Crosstalk Correction With Principal Component Analysis In Gait And Cycling, Jordan Skaro, Scott J. Hazelwood, Stephen M. Klisch

Biomedical Engineering

Principal component analysis (PCA) has been used as a post-hoc method for reducing knee crosstalk errors during gait analysis. PCA minimizes correlations between flexion–extension (FE), abduction–adduction (AA), and internal–external rotation (IE) angles. However, previous studies have not considered PCA for exercises involving knee flexion angles that are greater than those typically experienced during gait. Thus, the goal of this study was to investigate using PCA to correct for crosstalk during one exercise (i.e., cycling) that involves relatively high flexion angles. Fifteen participants were tested in gait and cycling using a motion analysis system. Uncorrected FE, AA and IE angles were …

Design Of An Ultra-Wideband Frequency-Modulated Continuous Wave Short Range Radar System For Extending Independent Living, Toai-Chi Nguyen

Master's Theses

Falls in the disabled and elderly people have been a cause of concern as they can be immobilized by the fall and have no way to contact others and seek assistance. The proposed frequency modulated continuous wave (FMCW) short range radar (SRR) system, which uses ultra-wideband (UWB) signals can provide immediate assistance by monitoring and detecting fall events. The unique characteristics of this system allow for a frequency-based modulation system to carry out triangulation and sense the location of the fall through the usage of a continuous chirp signal that linearly sweeps frequency. This project focuses on the development, design …

Human Identity, Animal Identity, And Reflective Endorsement, Rachel D. Robison-Greene

Between the Species

In this paper, I will argue that philosophers have overestimated the value of reflective endorsement. Introspection does not, as many philosophers have supposed, shine a searchlight on a person’s authentic identity. Our “selves” are not as transparent to us as we would like to think. In fact, much of the work done in an introspective mood is confabulation or rationalization rather than genuine self-discovery. I will argue that if this is the case, the outputs of the reflective endorsement process are not inherently normative in the way that thinkers like Harry Frankfurt and Christine Korsgaard have suggested.

If this is …

Trudging The Road Of Happy Destiny: The Gift Economy In Early Alcoholics Anonymous History And The Creation Of The Big Book, Timothy J. Parker

History

In 1939, Bill Wilson and his peers published Alcoholics Anonymous: The Story of How Many Thousands of Men and Women Have Recovered from Alcoholism, and in doing so, codified a spiritual gift economy through which millions of people have recovered from alcoholism and other addictions. This project examines the pragmatic formulation of this economy and argues its origins were driven as much by self-interest as altruism. It further explores the syncretic leadership of Bill Wilson and his mark on "The Big Book."

Food Stamp Enrollment And Mental Health: An Implicit Tax On The Poor, James Calvin Hasbany

Economics

Objectives. This study examines whether food stamp participation status impacts the mental health of its recipients.

Methods. We use 2017 data from the Michigan Panel Study of Income Dynamics to construct a propensity score model to match treated and control individuals, circumventing inherent selection bias and estimating causal effects.

Results. We find that enrolling in food stamps within the past 30 days increases the frequency of emotional distress over the same timeframe, manifesting specifically in more frequent feelings of sadness, nervousness, hopelessness, ‘everything being an effort,’ and worthlessness.

Conclusions. Food stamp enrollment harms mental health more than it benefits it, …

Physical Activity Guidelines For People With Alzheimer’S Disease Of Various Ambulatory And Cognitive Status, Amanda Katherine Wright

Kinesiology and Public Health

With the rapidly growing elderly population in the United States, the number of people diagnosed with dementia and Alzheimer’s Disease (AD) is increasing dramatically. For these patients, it is crucial to slow the rate of progression. Research has proven that exercise improves cognition, and recent findings suggest a similar association among those with AD. However, this is complicated by the large majority of AD patients becoming non-ambulatory as the disease progresses. Thus, there is a large gap in the literature to meet the needs of non-ambulatory AD patients working to slow their disease’s progression. The first purpose of this article …

Comparing Radiation Shielding Potential Of Liquid Propellants To Water For Application In Space, John Czaplewski

Master's Theses

The radiation environment in space is a threat that engineers and astronauts need to mitigate as exploration into the solar system expands. Passive shielding involves placing as much material between critical components and the radiation environment as possible. However, with mass and size budgets, it is important to select efficient materials to provide shielding. Currently, NASA and other space agencies plan on using water as a shield against radiation since it is already necessary for human missions. Water has been tested thoroughly and has been proven to be effective. Liquid propellants are needed for every mission and also share similar …

Solar Soiling Mitigation, Claire Desmith

Electrical Engineering

This senior project aims to mitigate performance losses that occur in Photovoltaic (PV) systems due to soiling of the panels. Soiling is the natural occurrence of debris accumulation on panels, depending on local climate conditions. Soiling loss refers to efficiency lost due to dirt and dust accumulation on the panels. The debris reduces system output by shading on a smaller scale. In addition to uniform soiling, corner soiling is observed in framed modules as debris collects in the corners of the modules. While solutions currently exist to clean modules to mitigate soiling losses, these solutions are often expensive and time …
