A hybrid prediction approach using machine learning and physics based models applied to power electronic circuits
No full textThis thesis covers the increasing usage of machine learning techniques in the field of power electronics. These uses are broad and efficient, but not without flaws. The major flaw being the requirement of time to collect data if there is not pre-existing datasets available. To combat this, a hybrid combination of existing physics-based modeling and data-driven modeling is proposed to limit the high computational strain of physics-models while simultaneously preventing the need for large pre-existing datasets. This method is then simulated and tested on a buck-converter with several disturbances applied to it to stimulate non-linear dynamics known as bifurcations that cannot be easily predicted by physics-based methods. The results show that hybrid methodology is more efficient and robust than data-driven methods alone and can efficiently predict the output of a system even when under the effect of bifurcations
Homecoming: Examining built relationships that influence historically black college and university student experiences
Get PDFMaintaining and increasing student retention is a challenge for small institutions especially small private Historically Black Colleges and Universities (HBCU). There are factors which contribute to this problem of practice and solutions that could increase student retention given more research and analysis. The purpose of this instrumental case study was to explore and examine the campus professional-student relationships to better understand the first-generation/first-time college student’s experience and how these relationships may influence their retention. This study examined the experiences of three Edward Waters University students to understand a problem of practice experienced at Edward Waters University and many others, student retention. The primary research questions for this study included: (1) How do first-generation/first-time college HBCU students enrolled between 2018 and 2022 describe their campus professional-student relationships? (2) How have the experiences within the campus professional-student relationships influenced their retention? The data collected included two semi-structured interviews with each participant conducted over a three-month period. Findings are presented in the form of narratives, themes, and assertions. The themes emerged by looking across the participants’ narratives and were developed into assertions after a thorough analysis and triangulation of the data. Assertion One identified that a meaningful campus professional-student relationship that supports retention includes behaviors that foster change, accountability, and connection. Assertion Two captured the role of leadership, call to service, and institutional pride as vehicles for supporting student retention. Finally, Assertion Three provided insight into how working through trouble with a trusted mentor served as a vehicle for change that supported retention. In combination, these three assertions illustrate key behaviors or activities of these relationships and how mentor-like relationships intentionally entered into by campus professionals and students had a strong influence on students’ retention choices. The study concludes with a discussion of the limitations of findings, implications and recommendations for practice, and recommendations for future research

Workplace Traumatic Stress and Mental Health Sequelae among Public Safety Telecommunications Officers in Florida
Get PDFBackground: Public safety telecommunications officers (PSTCOs), aka emergency “dispatchers,” are exposed to workplace traumatic stress and can experience situations characterized by uncertainty, communication difficulties, and a lack of resources. Traumatic stress experienced by emergency dispatchers has led to mental health symptoms. Purpose: This paper aims to describe the results of a study examining the patterns of workplace traumatic stress and the relationship between workplace traumatic stress and mental health concerns among a sample of PSTCOs. Methods: PSTCOs (n=54) participated in a cross-sectional, anonymous survey including screeners for depression, anxiety, post-traumatic stress disorder (PTSD), suicidal thoughts, and harmful alcohol use. Respondents also completed the Life Events Checklist (LEC) to screen for exposure to emergency calls identified as having the potential to induce traumatic stress. Results: 18.4% of respondents reported experiencing moderate to severe levels of depression, and 12% reported moderate to severe anxiety. Of the sample, 14% met the criteria for a provisional diagnosis of PTSD, 40% reported hazardous drinking levels, and 10% met the criteria of being at risk for suicide. Overall, 72.2% of PSTCOs experienced at least one form of job-related trauma and varied significantly by marital status. Poisson regression revealed statistically significant relationships between exposure to job-related traumatic events and screener scale scores. For example, those exposed to assault with a weapon had depression scores 2.29 points higher compared to those who were not exposed (p≤0.05). Discussion: Employing organizations of PSTCOs should strive to incorporate comprehensive wellness programs emphasizing education, prevention, early intervention, and recognition of traumatic stress among dispatchers. These programs should emphasize peer support and non-punitive policies to encourage help-seeking. In addition, given that findings in this study indicate exposure to traumatic emergency calls predicts PTSD symptomology, legislation could consider including PSTCOs in Florida Statute 118.1215
Sedentary time and prescriptions medication use among United States adults: 2017-2018 NHANES.
No full textBackground: Prescription medication usage has been used as a predictor of disease prevalence and overall health status. Evidence suggests an inverse relationship exists between polypharmacy, which is the use of 5 or more medications, and physical activity participation. However, there is limited evidence examining the relationship between sedentary time and polypharmacy in adults. The aim of this study was to examine the associations between sedentary time and polypharmacy in a large nationally representative sample of US adults. Methods: Study sample (N = 2879) included nonpregnant adult (≥20 y old) participants from the 2017–2018 National Health and Nutrition Examination Survey. Self-reported minutes per day of sedentary time were converted to hours per day. The dependent variable was polypharmacy (≥5 medications). Results: Analysis revealed that for every hour of sedentary time, there was 4% greater odds of polypharmacy (odds ratio, 1.04; 95% confidence interval, 1.00–1.07, P = .04) after adjusting for age, race/ethnicity, education, waist circumference, and the interaction term between race/ethnicity and education. Conclusion: Our findings suggest increased sedentary time is associated with an increased risk of polypharmacy among a large nationally representative sample of US adults
