Internal Model Control (Imc)-Based Active And Reactive Power Control Of Brushless Double-Fed Induction Generator With Notch Filter, Ahsanullah Memon, Mohd Wazir Bin Mustafa, Zohaib Hussain Laghari, Touqeer Ahmed Jumani, Waqas Anjum, Shafi Ullah, Muhammad Naveed Aman

School of Computing: Faculty Publications

The increase in demand for electricity and, in particular, green energy has put renewable energy systems at the focal point of energy policy worldwide. The higher reliability of brushless doubly fed induction generators (BDFIGs) makes them suitable for offshore and remote wind energy generation (WEG) applications. Besides, controlling the active and reactive powers in an electrical power system is critical for optimal voltage regulation, reduced power losses, and enhanced utilization of installed equipment. However, the existing literature on BDFIG’s active and reactive power control highlights the poor dynamic response and high transients with harmonic generation during inductive load insertion. It …

For purposes of this study, social value is explored through the operational processes of higher education …

Combining Solution Reuse And Bound Tightening For Efficient Analysis Of Evolving Systems, Clay Stevens, Hamid Bagheri

School of Computing: Conference and Workshop Papers

Software engineers have long employed formal verification to ensure the safety and validity of their system designs. As the system changes—often via predictable, domain-specific operations—their models must also change, requiring system designers to repeatedly execute the same formal verification on similar system models. State-of-the-art formal verification techniques can be expensive at scale, the cost of which is multiplied by repeated analysis. This paper presents a novel analysis technique—implemented in a tool called SoRBoT—which can automatically determine domain-specific optimizations that can dramatically reduce the cost of repeatedly analyzing evolving systems. Different from all prior approaches, which focus on either tightening the …

Amplification Of Black Vulture (Coragyps Atratus) Dna From Regurgitated Food Pellets, Daniel R. Taylor, Bryan M. Kluever, John S. Humphrey, Iona M. Hennessy, Amber Sutton, William E. Bruce, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Studies that rely on noninvasive collection of DNA for birds often use feces or feathers. Some birds, such as vultures, regurgitate undigested matter in the form of pellets that are commonly found under roost sites. Our research demonstrates that regurgitated pellets are a viable, noninvasive source of DNA for molecular ecology studies of vultures. Our objectives were to amplify 5 microsatellite loci designed for distinguishing Turkey Vultures (Cathartes aura) and Black Vultures (Coragyps atratus) in a single, multiplexed PCR, and to determine how long the target nuclear DNA persists after a vulture pellet is regurgitated and …

Motivating Students To Participate In The German As A Foreign Language Classroom, Joanna Walton

Honors Program: Senior Projects (Public)

This details how to motivate students in the German as a foreign language class to participate and engage in the learning process. Increasing motivation in students is a struggle with which all teachers are familiar, but teachers of foreign languages have a particular challenge because of the intimidation students feel when faced with producing assignments and content in a new language. This topic is also of interest to foreign language educators because student retention is becoming a serious problem, leading many school districts to cut smaller language programs like French and German. Maintaining an engaging classroom environment, where students participate …

A Comparison Of Nebraska Urban, Rural, And Reservation Schools' Readiness To Achieve Nebraska State Music Standards, Amber E. Knight

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

Every person has a unique perspective through which the concept of music education is filtered, and for good reason: music classrooms and programs across the United States are very different. Programs are dissimilar in everything from tangible items, such as facilities and available teaching materials, to foundational frameworks, including curriculum and program philosophy. Local geographical and cultural contexts contribute to the dissimilarity of music programs across the United States, and even those within the same region or state. The purpose of this study was to examine the commonalities and differences in school climate and access to resources among urban, rural, …

Transformational Leadership, Sarah Stepanek, Megan Paul

Umbrella Summaries

What is transformational leadership?

Transformational leadership refers to leadership behaviors that transcend the basic employment contract and help motivate followers to achieve beyond expectations (Antonakis et al., 2003; Bass, 1999). Transformational leaders seek to “uplift the morale, motivation, and morals of their followers” (Bass, 1999, p. 9). Through the four facets of transformational leadership (idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration), transformational leaders help followers create meaning, selfactualize, feel part of a collective, find greater self-worth, and achieve great things (Bass, 1999). The dimensions of transformational leadership are further detailed below.

► Idealized influence: This dimension of transformational …

Microfluidic Device For Localized Electroporation, Justin Brooks, Arian Jaberi, Ruiguo Yang

Department of Mechanical and Materials Engineering: Faculty Publications

Electroporation is a common method of transfection due to its relatively low risk and high transfection efficiency. The most common method of electroporation is bulk electroporation which is easily performed on large quantities of cells yet results in variable levels of viability and transfection efficiency across the population. Localized electroporation is an alternative that can be administered on a similar scale but results in much more consistent with higher quality transfection and higher cell viability. This paper discusses the creation and use of a simple and cost-effective device using porous membrane for performing localized electroporation.

Insect Pest Management With Sex Pheromone Precursors From Engineered Oilseed Plants, Hong-Lei Wang, Bao-Jian Ding, Jian-Qing Dai, Tara J. Nazarenus, Rafael Borges, Agenor Mafra-Neto, Edgar B. Cahoon, Per Hofvander, Sten Stymne, Christer Löfstedt

Center for Plant Science Innovation: Faculty Publications

Pheromones have become an environmentally friendly alternative to conventional insecticides for pest control. Most current pheromone-based pest control products target lepidopteran pests of high-value crops, as today’s manufacturing processes cannot yet produce pheromones at low enough costs to enable their use for lower-value crops, especially commodity crops. Camelina sativa seeds genetically modified to express (Z)-11-hexadecenoic acid, a sex pheromone precursor of several moth species, provided the oil from which the precursor was isolated, purified and transformed into the final pheromone. Trap lures containing this pheromone were then assessed for their capacity to manage moth pests in the field. Plant-derived pheromone …

Origins Of High Latitude Introductions Of Aedes Aegypti To Nebraska And Utah During 2019, Andrea Gloria-Soria, Ary Faraji, Jeff Hamik, Gregory White, Shanon Amsberry, Matthew Donahue, Bryan Buss, Evlyn Pless, Luciano Veiga Cosme, Jeffrey R. Powell

Department of Educational Psychology: Faculty Publications

Aedes aegypti (L.), the yellow fever mosquito, is also an important vector of dengue and Zika viruses, and an invasive species in North America. Aedes aegypti inhabits tropical and sub-tropical areas of the world and in North America is primarily distributed throughout the southern United States states and Mexico. The northern range of Ae. aegypti is limited by cold winter months and establishment in these areas has been mostly unsuccessful. However, frequent introductions of Ae. aegypti to temperate, non-endemic areas during the warmer months can lead to seasonal activity and disease outbreaks. Two Ae. aegypti incursions were …

Differential Effects Of Protein Isolates On The Gut Microbiome Under High And Low Fiber Conditions, Marissa Behounek

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Protein isolates are a growing market share in the food industry both as food ingredients and as supplements. All dietary habits can influence and alter the gut microbiome; however, little is known about how protein isolates from different sources will change the composition and function of the gut microbiota under high and low fiber conditions. The study aims to determine the microbiome response to plant and animal protein isolates under high- and low-dietary fiber (H/LDF) conditions. Six commercially available protein isolates (beef, egg white, milk, pea, and two soy protein isolates) were subjected to in vitro enzymatic digestion and dialysis …

Beta-adrenergic agonists (β-AAs) are widely used supplements in beef and pork production to improve feed efficiency and increase lean muscle mass, yet little is known about the molecular mechanism by which β-AAs achieve this outcome. Our objective was to identify the influence of ractopamine HCl and zilpaterol HCl on mitochondrial respiratory activity in muscle satellite cells isolated from crossbred beef steers (N = 5), crossbred barrows (N = 2), Yorkshire-cross gilts (N = 3), and commercial weather lambs (N = 5). Real-time measurements of oxygen con­sumption rates (OCRs) were recorded using extracellular …

Spmc 350: Sports Data Analysis And Visualization, Matt Waite

UNL Faculty Course Portfolios

Sports Data Analysis and Visualization isa required course for all Sports Media and Communications majors at the University of Nebraska-Lincoln. The course is an introduction to using data and code to reveal stories in sports data. Sports media students, as a general rule, have very little experience with code, so the course utilizes a considerable amount of customized content specifically tailored to the course and aimed at the level of the typical student. Previous iterations of the course used an online static textbook, where students were expected to follow along and execute code blocks, but the book had no facilities …

Key Factors Surrounding The Survival And Thrival Of Rural Schools In Nebraska Through The Eyes Of Superintendents: A Mixed Methods Study, Sadie Coffey

Department of Educational Administration: Dissertations, Theses, and Student Research

Rural school success is crucial for the Nebraska education system. Without rural schools, many students and families would be without access to high quality educational opportunities. Despite the importance of rural education, the number of rural schools in Nebraska continues to decline, and “one thing is clear from academic research on rural schools: closings and consolidations can drastically change the flavor of civic life in a rural community” (McCullum & Merrefield, 2019, p. 1). Identity loss and identity crisis theories may explain why these rural schools in Nebraska continue to survive and thrive. Without the rural school, a community and …

Education Anywhere? A Constructivist Grounded Theory Study Of Montessori Around The World, Victoria J. Johnson

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Providing education for children residing in remote or difficult-to-access locations, including children in refugee and displacement camps, is a staggering global challenge. In addition to logistical challenges (such as access, infrastructure, teaching professionals and resources), differences in language, culture, environment, and values render conventional (i.e., Western-based, traditional) modes of education unfeasible and frequently ineffective. However, a strengths-based lens reminds us that communities have the capacity to initiate solutions when they have access to the right tools. Historically underrepresented in the literature, Montessori education has been used for over a century by communities all over the world to prepare children through …

Understanding Unwanted Sexual Experiences Of Transgender And Gender Diverse Individuals: An Interpretative Phenomenological Study, Melissa Larosa

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Transgender and gender diverse (TGD) people represent a small percent of the population and yet, they experience sexual violence at disproportionately high rates compared to their cisgender counterparts (Grant et al, 2011; James et al., 2016). The purpose of this interpretative phenomenological study is to gain a more nuanced understanding of the role that unwanted sexual experiences play in the lives of transgender and gender diverse people, particularly in relation to how they conceptualize their gender identity and the construct of posttraumatic growth (PTG). Semi-structured interviews were conducted with eight TGD participants who met the inclusion criteria. Two superordinate (i.e., …

Optimization Of A Novel Barnes Maze Protocol For Assessing Antioxidant Treatment Of Traumatic Brain Injury, Connor C. Gee

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Current preclinical research into traumatic brain injury focuses heavily upon cellular and molecular testing to determine the effects of injury and potential benefits of neuroprotective treatments. While this may be a useful method, some argue that an increased focus on behavioral testing could lead to better clinical translation as these assays assess the longer term, downstream effects from a brain injury. The most characterized behavioral tests used in traumatic brain injury research are the spatial learning and memory paradigms, Morris Water Maze and Barnes Maze. The Morris Water Maze is the most used of theses paradigms and relies on spatial …

Access To Online Formative Assessments In Introductory Biology Courses: Investigating Barriers To Student Engagement, Allison M. Upchurch

School of Biological Sciences: Dissertations, Theses, and Student Research

Instructors use a variety of online formative assessment (FA) activities to support learning outside of class. Previous studies have revealed barriers for students in online courses, but little is known about the barriers students experience when completing online FA assignments. Understanding these barriers to access is critical to fostering more inclusive learning for all students. Using a framework from previous work in online learning, we examined student perceptions of online FA access with respect to five barrier categories: technical resources, instructor organization, social interactions, personal engagement, and learning environment. We developed and administered a survey to over 1200 undergraduate biology …

Methanogen Metabolic Flexibility, Sean R. Carr

School of Biological Sciences: Dissertations, Theses, and Student Research

Methanogens are obligately anaerobic archaea which produce methane as a byproduct of their respiration. They are found across a wide diversity of environments and play an important role in cycling carbon in anaerobic spaces and the removal of harmful fermentation byproducts which would otherwise inhibit other organisms. Methanogens subsist on low-energy substrates which requires them to utilize a highly efficient central metabolism which greatly favors respiratory byproducts over biomass. This metabolic strategy creates high substrate:product conversion ratios which is industrially relevant for the production of biomethane, but may also allow for the production of value-added commodities. Particularly of interest are …
