Introduction To Discrete Mathematics: An Oer For Ma-471, Mathieu Sassolas

Open Educational Resources

The first objective of this book is to define and discuss the meaning of truth in mathematics. We explore logics, both propositional and first-order , and the construction of proofs, both formally and human-targeted. Using the proof tools, this book then explores some very fundamental definitions of mathematics through set theory. This theory is then put in practice in several applications. The particular (but quite widespread) case of equivalence and order relations is studied with detail. Then we introduces sequences and proofs by induction, followed by number theory. Finally, a small introduction to combinatorics is …

Lessons Learned From The Hiv/Aids Pandemic And Access To Medicines For Covid-19 Treatment, Thalia Le

Independent Study Project (ISP) Collection

There is an imminent need to address the healthcare disparities in accessing all COVID-19 medicinal products in developing countries. While logistical issues like inadequate production facilities such as the lack of vaccines administration capacity, storage issues, gap between supply and demand as well as vaccine hesitancy can certainly play a part in impeding COVID19 medicines distribution, patent monopolies and intellectual property protection laws further exacerbated the problem, especially when vaccines were at its early stages of authorization. Historical and contemporary case studies of efforts to challenge patents on HIV AVRs treatment provide a useful lens through which we may glean …

Business Models For Post-Crisis Information Ecosystems, Antje Mays

Library Faculty and Staff Publications

Since early 2020, the global COVID-19 pandemic has interrupted activity across business, education, research, and communities. Public health safety precautions have forced drastic reductions in economic and educational activity, resulting in widespread economic uncertainty and sizeable budget cuts. With library budgets already declining since the 2001-2002 recession following the dotcom crash and more steeply since the 2007-2009 Great Recession spawned by the financial crash, the pandemic has accelerated trends that were already underway. Libraries’ reduced purchasing power places the information ecosystem at risk of contraction in the race to contain costs. While economic contexts and publishing forms have changed considerably. …

Design Optimization Of A Very High Power Density Motor With A Reluctance Rotor And A Modular Stator Having Pms And Toroidal Windings, Peng Han, Murat G. Kesgin, Dan M. Ionel, Rohan Gosalia, Nakul Shah, Charles J. Flynn, Chandra Sekhar Goli, Somasundaram Essakiappan, Madhav Manjrekar

Power and Energy Institute of Kentucky Faculty Publications

This paper proposes a new high power density permanent magnet (PM) motor design for traction applications to achieve the 50kW/L target set by the US Department of Energy by increasing the torque capability and operating speed compared to conventional PM machine topologies. A large-scale multi-objective design optimization based on 2D finite element analysis (FEA) and differential evolution algorithm was conducted to achieve the best trade-off among high efficiency, high power density and high power factor. The torque-speed envelopes are also checked for the Pareto front designs to make sure they have a constant power speed ratio of at least 3:1. …

Generalized Energy Storage Model-In-The-Loop Suitable For Energy Star And Cta-2045 Control Types, Huangjie Gong, Evan S. Jones, A. H. M. Jakaria, Aminul Huque, Ajit Renjit, Dan M. Ionel

Power and Energy Institute of Kentucky Faculty Publications

The paper proposes a generalized energy storage (GES) model for battery energy storage systems (BESS), electric water heaters (EWH) and heating, ventilation, and air-conditioning (HVAC) systems. The analogies, including state of charge versus water temperature differential, are identified and explained, and models-in-the-loop (MIL) are introduced, which are compatible with the Energy Star and CTA-2045 general specifications and command types. Emphasis is placed on the proposed EWH model as it needfully fulfills a gap in present literature. The corresponding MIL has been implemented in the DER integration testbed, which was originally developed by EPRI, and satisfactorily validated against experimental results. A …

On The Modeling Of Bearing Voltage And Current In Pwm Converter-Fed Electric Machines Using Electromagnetic Finite Element Analysis, Peng Han, Yibin Zhang, Murat G. Kesgin, Greg Heins, Dean Patterson, Mark Thiele, Dan M. Ionel

Power and Energy Institute of Kentucky Faculty Publications

Bearing voltages and resulting currents in electric machines driven by PWM converters with fast switching and high dv/dt can cause premature bearing failures. With the transition from conventional Si devices to wide bandgap (WBG) devices and increase in switching frequency, bearing voltages and currents become more significant and need to be addressed from the early design stage. This paper proposes to use coupled field-circuit electromagnetic finite element analysis (FEA) to model bearing voltage and current in electric machines, which takes into account the influence of distributed winding conductors and frequency-dependent winding RL parameters. The three known bearing current types are …

Liquid-Vapor Distributions In Evacuated Small Diameter Channels For Improved Accuracy Of Initial Conditions In Modeling Of Oscillating Heat Pipes, Travis Mayberry

Mechanical Engineering Research Theses and Dissertations

Oscillating heat pipes, also known as pulsating heat pipes, are increasingly becoming a preferred high-performance thermal ground plane in a variety of heat spreading applications due to a number of advantages over traditional copper-water wicked heat pipes, including their lighter weight, thinner profiles, simpler fabrication, and greater variety of material and working fluid options. A major barrier to even wider adoption, however, is the lack of comprehensive analytical models to simulate their performance. A key input to first principles models simulating the fundamental physics of the devices is the initial condition of liquid and vapor segment lengths and their distribution …

Factors That Influence The Choice To Major In Stem For Latino And Non-Latino Students And Professionals, Ivan Olivas

Honors Theses

Latinos are the largest minority group in the United States, with 18.5 percent of the nation’s population. However, when it comes to Latinos in STEM, they represent only 8 percent of all STEM workers. This disparity can be largely traced to disproportionally low numbers in graduation rates in high school and college, in conjunction with the lack of exposure to STEM fields and access to rigorous K-12 curriculums associated with STEM pathways. The survey incorporated into this research investigates which factors influence Latinos in choosing a STEM major. The survey questions focused on high school academics, parental educational attainment, home …

Peeling Off The Proof: Using Peel-Away Polymer Technology In The Collection Of Ignitable Liquids During Arson Investigations, Cassidy Laney

Honors Theses

Determining the presence of ignitable liquids at the scene of a fire is a key part of any arson investigation. Residues of ignitable liquids are most often found in absorbent or porous material as there is a chance that some liquid will remain in the pores of the substrate after a fire. Unfortunately, the collection of ignitable liquids from porous surfaces such as concrete is especially difficult given the fixed nature of the substrate. Several on-site collection techniques have been developed to collect the ignitable liquid from the concrete directly at the scene, however they each have their own drawbacks …

Re-Evaluating Standards Of Human Subjects Protection For Sensitive Health Data In Social Media Networks, Kar-Hai Chu, Jason Colditz, Jaime Sidani, Michael Zimmer, Brian Primack

Computer Science Faculty Research and Publications

This study addresses ethical questions about conducting health science research using network data from social media platforms. We provide examples of ethically problematic areas related to participant consent, expectation of privacy, and social media networks. Further, to illustrate how researchers can maintain ethical integrity while leveraging social media networks, we describe a study that demonstrates the ability to use social media to identify individuals affected by cancer. We discuss best practices and ethical guidelines for studying social media network data, including data collection, analysis, and reporting.

Reducing Parental Stress In Neonatal And Pediatric Intensive Care Units, Nancy M. Abbene

Electronic Theses and Dissertations

Abstract

The neonatal intensive care unit (NICU) and pediatric intensive care unit (PICU) are highly operational and highly active environments. Health care workers must react quickly to care for patients and provide life-saving measures fundamental to favorable patient outcomes. Caregivers of this critical patient population are often overlooked as the healthcare team prioritizes patient’s needs. In addition, medical equipment, machines, and monitors have multiple safety alarms sounding frequently and contributing to high levels of parental stress upon their child’s admission to the NICU and PICU. Lack of giving adequate prominence to the value of caregiver support services in the hospital …

The Tarheel Victorian: H.H. Brimley And The North Carolina State Museum In Raleigh (1880-1946), Robert Alexander Stroud

Masters Theses

Following North Carolina's experience during the American Civil War and Reconstruction, the museum was born out of a desire to bring greater economic investment into the North Carolina economy. Its first director H.H. Brimley (1861-1946) transformed the museum into a thriving institution that attracted hundreds of thousands of visitors annually by the 1940s. The museum helped Raleigh's transformation from a backwater of the Old South into a thriving metropolis of Post-Reconstruction by kick-starting a wave of tourism and popular education with its exhibits on state history and science. This thesis argues that this museum played a critical role not only …

Business Interruption Insurance: The Future Of Pandemic Exclusions, Micaylee R. Uhls

Southern Illinois University Law Journal

The COVID-19 pandemic presented many challenges and businesses were not immune. Corporations and small businesses alike faced closures due to the pandemic and related governmental shutdowns which left them desperate for the lifeboat that is insurance coverage. However, the majority of these businesses were excluded from this coverage. Business Interruption Insurance is the “ark” that keeps business afloat when they are faced with temporary closures. However, when insurers were looking for their lifeboat, they found nothing but a quickly deflating raft.

Insurance, in its most simple terms, is a contract for balancing of risks. Insurance policy exclusions are the primary …

Autonomous Vehicle Communication Strategies Modeled In Virtual Reality, Nick N. Ferenchak Ph.D

Data

We sought to better understand how autonomous vehicle (AV) communication strategies impact human road users’ perceptions and behaviors. More specifically, we explored the impact of different external human-machine interface (eHMI) designs on understanding, task load, comfort, trust, acceptance, and reaction time. To accomplish this, we created virtual reality (VR) scenarios where human participants interacted with AVs. Participants experienced biking, driving, and pedestrian simulators and were brought back after initial testing to explore acclimation and learning effects. In terms of perceptions, the presence of an eHMI was the strongest predictor of understanding, comfort, trust, and acceptance outcomes in the statistical models …

Exploring Traffic Safety Problems And Challenges Of Older Roads’ Users In Louisiana: Causes And Countermeasures, Hany Hassan Ph.D, Saba Doulabi

Data

It is well established that older pedestrians and drivers with 65 years and above are among the most vulnerable road users. As the number and proportion of older road users (as drivers and pedestrians) grows in many countries, as well as their share in pedestrians’ and drivers’ crashes and injuries, it behooves transportation researchers to further investigate the safety and mobility challenges of older road users. This study aims mainly to provide a comprehensive investigation of older pedestrians’ and drivers’ safety challenges. To this end, a three-fold research approach is designed to thoroughly examine older road users’ safety challenges as …

Calculating Pile Downdrag: Experimental And Numerical Investigations, Hai Lin, Shengli Chen, Hussein Alqrinawi

Data

Piles can be exposed to significant settlement (i.e., downdrag) and compressive force (i.e., dragload) if embedded in consolidating ground. Downdrag has been included in the design of piles, but there is uncertainty about how downdrag and dragload are efficiently considered in the pile design due to the differences in the existing design methods (e.g., AASHTO and FHWA). Although several field monitoring programs were successfully conducted on pile downdrag, fully instrumented pile model tests are still needed to investigate the responses at the soil-pile interface to improve the design of pile downdrag. This research focused on investigating the downdrag and skin …
