Structural Vibration Damping By The Use Of Poro-Elastic Layers: A Summary, Yutong Xue, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

A properly designed limp porous materials such as fibrous layers can provide damping equivalent to conventional viscoelastic dampers while providing advantages such as light weight and effective sound absorption. This then allows porous layers to be used as multi-functional noise and vibration control solutions in automotive and aerospace applications. Further, the addition of bulk elasticity to the solid phase of the porous medium is beneficial since it improves damping performance compared to equivalent limp treatments. In the work summarized here, porous media, such as fibers and foams, were designed to serve as treatments for various vibrating structures to examine their …

Modeling Of Sound Radiation From A Loaded Rolling Tire, Won Hong Choi, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

In recent work it has been possible to model the surface vibration of a loaded rolling tire, including the influence of the acoustic mode that forms within the tire cavity. For example, it has been found that the acoustic cavity mode splits owing to the deformation of the tire when it is loaded, and that the split widens owing to Doppler effects when the tire is rolling. It has also been demonstrated that the force at the hub that results from the acoustic cavity mode is strongly dependent on interaction with circumferential structural modes of the treadband. The finite element …

Changing The Paradigm For Pesticide Resistance Management, David R. Shaw, Amy Asmus, Jill Schroeder, David Ervin

Economics Faculty Publications and Presentations

Collaborative action on the part of all stakeholders in pest management is essential to effectively address the challenges of pesticide resistance. The US Environmental Protection Agency, through its Pesticide Program Dialogue Committee, recently posted a report on pesticide resistance management and the role the Agency can play in these efforts. In this perspectives piece, we commend the Agency for acknowledging these needs, and encourage implementation of the recommendations. We urge all stakeholders to follow the example set by EPA to engage openly, listen to other stakeholders, and determine their role as part of the broader community that is needed to …

The Effects Of Dormant Season Burning And Flooding On Invasive Cattail, Typha X Glauca, On Rainy Lake And Lake Kabetogama In Northern Minnesota, Erika Meints

All NMU Master's Theses

Typha x glauca is one of the most invasive plants in North America. The plant exhibits hybrid vigor and displaces native flora by rapidly forming dense monotypic stands that can break free from the substrate and form floating mat types when established. I tested the effects of prescribed burning, on Typha x glauca in wetlands to adjacent large lakes in Voyageurs National Park in northern Minnesota. My team surveyed four wetlands that were burned in late winter of 2020-21, and six that were unburned controls. Pre-burn data was also collected for all ten wetlands. Pre-flooding data from other wetlands within …

Control Of Pausing In Rich-Lean Transitions By Spatially Localized And Spatially Diffuse Stimuli, Carson S. Yahrmarkt

All NMU Master's Theses

Signaled transitions from rich (favorable) to lean (less favorable) schedules of reinforcement (i.e., rich-lean transitions) can disrupt operant behavior. Previous literature suggests that disruptions in these transitions could occur because individuals engage in other behavior that reduces contact with the schedule-correlated stimuli. My thesis project evaluated this possibility by using different stimuli to manipulate the ease by which rats could reduce contact with schedule-correlated stimuli during signaled rich-lean transitions. We arranged a two-component multiple fixed ratio-fixed ratio (FR-FR) schedule to evaluate effects of different types of schedule-correlated stimuli on pausing in rich-lean transitions using rat subjects. Components had equivalent FR …

“Early Covid” Changes In Parenting, Education, And Work On Parental Stress: A Gendered Comparison Of Canadian Parents, Holly Harris

Undergraduate Honors Theses

In May 2020, data were collected through survey as the COVID-19 pandemic was unfolding and still in its “early” months. The sample N=1,208 is of Canadian parents in a residential romantic relationship, who live with a residential child under the age of eighteen years old, who have access to the internet, and speak English or French. I examine how disruptions to child’s education/daycare, work, and parental childcare activities predicted parental stress through regression models. Findings indicate that fathers and mothers stress since the onset of COVID-19 were the same and that gender was not a moderator to parental stress. A …

What Are Our Unenumerated Rights As Americans? An Analysis Of The Ninth Amendment And The Fourteenth Amendment’S Privileges Or Immunities Clause Using Original Intent Originalism, Bryan Habashi

Undergraduate Honors Theses

This research aims to determine what the author believes is the original intent of the Ninth Amendment and the Privileges or Immunities Clause of the Fourteenth Amendment. The author plans to do this through a variation of original intent originalism, the philosophy that the original meaning of the text should be what the framers (and secondarily the ratifiers) said the text means. The author believes that original intent originalism is the correct method to interpret the Constitution. This thesis will begin with a defense of this philosophy. Then the author will use this philosophy to determine the original intent of …

Notably, the intensive use of pesticides can cause detrimental effects (i.e., chemical stressors) on animal behavior. The aim of this study was to determine the short-term exposure effects (5-day) of an environmentally relevant pesticide mixture (low- and high-dose: metolachlor …

Evaluating How Well Active Fault Mapping Predicts Earthquake Surface-Rupture Locations, Chelsea Scott, Ramon Arrowsmith, Rachel Adam, Christopher Madugo, Joseph Powell, John Ford, Brian Gray, Ashley Streig, Multiple Additional Authors

Geology Faculty Publications and Presentations

Earthquake surface-fault rupture location uncertainty is a key factor in fault displacement hazard analysis and informs hazard and risk mitigation strategies. Geologists often predict future rupture locations from fault mapping based on the geomorphology interpreted from remote-sensing data sets. However, surface processes can obscure fault location, fault traces may be mapped in error, and a future rupture may not break every fault trace. We assessed how well geomorphology-based fault mapping predicted surface ruptures for seven earthquakes: 1983 M 6.9 Borah Peak, 2004 M 6.0 Parkfield, 2010 M 7.2 El Mayor–Cucapah, 2011 M 6.7 Fukushima-Hamadori, 2014 M 6.0 South Napa, 2016 …

Improved Fine-Scale Tropical Forest Cover Mapping For Southeast Asia Using Planet-Nicfi And Sentinel-1 Imagery, Feng Yang, Xin Jiang, Alan D. Ziegler, Lyndon Estes, Jin Wu, Anping Chen, Philippe Ciais

Geography

The accuracy of existing forest cover products typically suffers from “rounding” errors arising from classifications that estimate the fractional cover of forest in each pixel, which often exclude the presence of large, isolated trees and small or narrow forest clearings, and is primarily attributable to the moderate resolution of the imagery used to make maps. However, the degree to which such high-resolution imagery can mitigate this problem, and thereby improve large-area forest cover maps, is largely unexplored. Here, we developed an approach to map tropical forest cover at a fine scale using Planet and Sentinel-1 synthetic aperture radar (SAR) imagery …

Genesis Of The 1.45 Ga Kratz Spring Iron Oxide-Apatite Deposit Complex In Southeast Missouri, Usa: Constraints From Oxide Mineral Chemistry, Brandon Sullivan, Marek Locmelis, Bolorchimeg N. Tunnell, Cheryl M. Seeger, Marilena Moroni, Sarah Dare, Ryan Mathur, Thomas Schott

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Seven major and numerous lesser Fe oxide occurrences within the 1.47 Ga St. Francois Mountains terrane in Missouri (USA) have previously been described as iron oxide-apatite (IOA) and iron oxide-copper-gold (IOCG) deposits. Researchers speculate that these contain significant amounts of critical minerals, most notably rare earth elements and cobalt. One of the less-studied deposits in the region is the 1.455 Ga Kratz Spring deposit. The deposit consists of two steeply dipping magnetite bodies beneath 450 m of sedimentary cover. The genesis of the Kratz Spring deposit and its relationship to nearby IOA-IOCG deposits remains poorly constrained. To better understand the …

Effect Of Robotic Delivery Of Physical Activity And Fall Prevention Exercise In Older Adults: A Pilot Cohort Study, Christopher M. Wilson, Lori Boright, Wing-Yue Geoffrey Louie, Pourya Shahverdi, Sara K. Arena, Ronald Benbow, Jason R. Wilson, Qinghua Chen, Katie Rousso, Nathan Huang

Cardiology Articles

Introduction: The high prevalence of falls, lack of stability and balance, and general physical deconditioning are concerning issues for longevity and quality of life for adults aged 65 years and older. Although supervised delivery of the Otago Exercise Program (OEP) has demonstrated evidence of effectiveness in reducing fall risk of older adults, opportunities for ongoing unsupervised exercise performance are warranted. An option to facilitate exercise and performance of health behaviors may be via a social robot. The purpose of this study was to examine feasibility and initial outcomes of a robot-delivered fall prevention exercise program for community-dwelling older adults.

Methods: …

Persistent Heart Failure Despite Medical Therapy Leading To A Diagnosis Of Cardiac Amyloidosis, Diva Maraj, Sruthi Ramanan, Parth Y. Patel, Mumtaz Memon, Elise Hawes

Cardiology Articles

Cardiac amyloidosis is restrictive cardiomyopathy, commonly classified as either light-chain amyloidosis (AL) or transthyretin amyloidosis (ATTR), which can be further subdivided into wild-type (systemic senile amyloidosis) and hereditary ATTR amyloidosis. Advanced-stage, silent, and clinically undiagnosed amyloidosis has a poor prognosis, with a survival rate of six months and up to five years. We present a 72-year-old female with a past medical history of heart failure, with preserved ejection fraction, atrial fibrillation, systemic lupus erythematosus (SLE), and stage 3b chronic kidney disease, who presented with persistent shortness of breath, lower extremity pitting edema, jugular venous distension, and dyspnea despite optimal medical …

Crowdfl: Privacy-Preserving Mobile Crowdsensing System Via Federated Learning, Bowen Zhao, Ximeng Liu, Wei-Neng Chen, Robert H. Deng

Research Collection School Of Computing and Information Systems

As an emerging sensing data collection paradigm, mobile crowdsensing (MCS) enjoys good scalability and low deployment cost but raises privacy concerns. In this paper, we propose a privacy-preserving MCS system called CROWDFL by seamlessly integrating federated learning (FL) into MCS. At a high level, in order to protect participants' privacy and fully explore participants' computing power, participants in CROWDFL locally process sensing data via FL paradigm and only upload encrypted training models to the server. To this end, we design a secure aggregation algorithm (SecAgg) through the threshold Paillier cryptosystem to aggregate training models in an encrypted form. Also, to …

Depression, Anxiety, And Estimated Cardiorespiratory Fitness In College Students, Christian Ison

UNLV Theses, Dissertations, Professional Papers, and Capstones

Depression and anxiety disorders are two common mental health conditions worldwide. College students are considered a high-risk population for the development of these conditions. Improved cardiorespiratory fitness (CRF) has been shown to decrease depression and anxiety risk, symptoms, and severity but this relationship and the extent to which improved CRF can reduce these risks has yet to be examined in the college student population. Validated and reliable non-exercise estimated cardiorespiratory fitness (eCRF) algorithms could be used to identify relationships and associations with depression and anxiety severity levels among college students. The purpose of this study was to assess eCRF and …

Towards Reliable Hepatocytic Anatomy Segmentation In Laparoscopic Cholecystectomy Using U-Net With Auto-Encoder, Koloud Najem Alkhamaiseh

Dissertations

Despite the advantages of minimally invasive surgeries that depend heavily on vision, the indirect access and lack of the 3D field of view of the area of interest introduce some complications in the desired procedures. Fortunately, the recorded videos from these procedures offer the opportunity for intra-operative and post-operative analyses, to improve future performance and safety.

Deep learning models for surgical video analysis could therefore support visual tasks such as identifying the critical view of safety (CVS) in laparoscopic cholecystectomy (LC), potentially contributing to the reduction of the current rates of bile duct injuries in LC. Most bile duct injuries …

A Literature Review Of The Psychosocial Impacts On Livestock Producers And Veterinary Responders Involved With Depopulation During And After An Animal Health Emergency, Beth Galles

Capstone Experience: Master of Public Health

A vital aspect of an animal health emergency in the United States is removing and disposing of diseased and healthy animals through depopulation. It is frequently required to prevent the spread of diseases that affect human health or economic stability. Production animals are eventually slaughtered, but this does not negate the human-animal bond felt between these animals and their caretakers. There is increasing recognition that participation in depopulation may be a traumatic event requiring care for the individuals involved, including livestock producers and veterinarians. Despite this, limited resources are available for these individuals when an animal health emergency occurs. This …

Capstone Experience: Master of Public Health

The Division of Public Health (DPH) within the Nebraska Department of Health and Human Services (DHHS) is redesigning its State Health Assessment (SHA) and State Health Improvement Plan (SHIP) procedures. This study aimed to support the Nebraska DPH SHA/SHIP redesign evaluation plan by determining the local health department (LHD) health priority determination processes, Tribal and LHDs’ (T/LHD) CHA/CHIP methodology, and if any differences exist between rural & urban and small, medium, and large jurisdictional size health departments in Nebraska. The results show that most health departments utilize the MAPP process to conduct their CHA/CHIP, one tribal entity utilizes a different …

Understanding Gendered Risks For Severe Covid-19 Through Surveying The Gender Diverse Community, Arden Tyree

Capstone Experience: Master of Public Health

Early on in the pandemic, the medical community began noticing that men were more likely to be hospitalized, require admission to the ICU, and die of COVID-19 than women but few studies of COVID-19 make mention of gender diverse people, an often-overlooked population who may have vastly different experiences than non-gender diverse men or women. Their variations in gender and sex characteristics may also help provide further insight into which traits are protective or risk factors for this disease. This project used Poisson regression in order to analyze self-reported survey data. The major associations of interest will be between disease …

A Qualitative Analysis Of Candida Auris Laboratory Surveillance In Nebraska, Lissa M. Young

Capstone Experience: Master of Public Health

Objectives: Candida auris is an emerging pathogenic yeast that was first identified in Japan in 2009 and detected in the United States in 2015. As of 2020, C. auris has been reported in cases throughout 41 countries, including the United States. The ability of this species of yeast to spread rapidly and survive for long periods of time on surfaces, the high mortality rate of those infected, and its multidrug resistant phenotype, have rendered it a urgent public health threat (the highest threat level) by the United States Centers for Disease Control and Prevention beginning in 2019 (CDC, 2019). Since …
