Adaptive Underfrequency Load Shedding Based On Real Time Simulation, Mosab Salah Aldeen Mohamed Zeyada

Masters Theses and Doctoral Dissertations

Conventional Underfrequency Load Shedding (UFLS) is used to balance generation and load when underfrequency conditions occur. It sheds a fixed, predetermined amount of load irrespective of disturbance location. Several adaptive UFLS schemes are proposed in the literature. Recent research discussed utilizing synchrophasor messages to implement adaptive UFLS but these studies have been using virtual PMUs. Of late, hardware implementations for adaptive UFLS scheme using actual Phasor Measurement Units (PMUs) are reported but also these studies are based on small power systems. This study presents hardware implementation of adaptive UFLS based on real time simulation of IEEE39-bus system. The simulation tool …

A Remote Sensing Based Early Warning System For Algal Blooms In Kuwait Bay And Coastal Waters, Cameron Manche

Masters Theses

The Kuwait Bay and its coastal waters are being threatened by a perpetual hazard, the proliferation of harmful algal blooms (HABS). The frequency of HAB occurrences is a growing problem that is only reported subsequent to the onset of a HAB event. Little effort has been invested in investigating the spatial and temporal distribution of these events in Kuwait Bay and even less is known about their controlling factors. All previous studies within the Kuwait Bay have focused either on measuring nutrient availability and the biodiversity of algal species.

The overall study objective is four-fold: (1) to monitor the spatial …

Uaa Graduates: How Many Stay And Work In Alaska?, Alexandra Hill, Gunnar Knapp, Blake Steenhoven

ISER Reports

More and more people have been graduating from the University of Alaska Anchorage in the past decade. Do they stay in Alaska? What kinds of jobs do they have? How much do they earn? It turns out that most of them stay in Alaska for at least five years after they graduate, they work throughout the economy, and by five years after they graduate their average earnings double. Around one-quarter do leave within a few years. But Alaska’s population on the whole is transient, and it looks as if UAA graduates are no more likely than other Alaskans to leave …

The Effect Of Instruction In Alternative Solutions On American Ninth-Grade Algebra I Students' Problem Solving Performance, Erin Elizabeth Sagaskie

Dissertations

The purpose of this study was to investigate the effect of the use of an Alternative-Solution Worksheet (ASW) on American ninth-grade students' problem solving performance, and to determine the extent to which instruction in alternative solutions promotes "look back" strategies. "Look back" strategies are based on Polya's (1973) problem solving steps, and they are an examination of what was done or learned previously. The ASW was designed to encourage students to utilize "look back" strategies by generating alternative solutions to the problems. This mixed-methods study was conducted with two existing groups of ninth-grade Algebra I students. An experimental group of …

The Development Of Calculus In The Kerala School, Phoebe Webb

The Mathematics Enthusiast

The Kerala School of mathematics, founded by Madhava in Southern India, produced many great works in the area of trigonometry during the fifteenth through eighteenth centuries. This paper focuses on Madhava's derivation of the power series for sine and cosine, as well as a series similar to the well-known Taylor Series. The derivations use many calculus related concepts such as summation, rate of change, and interpolation, which suggests that Indian mathematicians had a solid understanding of the basics of calculus long before it was developed in Europe. Other evidence from Indian mathematics up to this point such as interest in …

Substrate Concentration Influences Effective Radial Diffusion Coefficient In Canine Cortical Bone, Kurt Farrell, Daniel O’Conor, Mariela Gonzalez, Caroline Androjna, Ronald J. Midura, Surendra N. Tewari, Joanne M. Belovich

Chemical & Biomedical Engineering Faculty Publications

Transport of nutrients and waste across osseous tissue is dependent on the dynamic micro and macrostructure of the tissue; however little quantitative data exists examining how this transport occurs across the entire tissue. Here we investigate in vitro radial diffusion across a section of canine tissue, at dimensions of several hundred microns to millimeters, specifically between several osteons connected through a porous microstructure of Volkmann's canals and canaliculi. The effective diffusion coefficient is measured by a "sample immersion" technique presented here, in which the tissue sample was immersed in solution for 18-30 h, image analysis software was used to quantify …

Goodness And Truth: An Essay On Ralph Hancock's The Responsibility Of Reason, Joseph M. Spencer

BYU Studies

Joseph Spencer explains the shift in thinking that occurred about five hundred years ago: very generally speaking, premoderns took the ideal to be metaphysically fundamental, and moderns take the physical to be metaphysically fundamental. Latter-day Saint thinkers may fall into one camp or the other. Ralph Hancock's The Responsibility of Reason is a defense of a premodern conception of the world, mobilized by an attempt to reveal real problems in certain modern conceptions of the world. But Hancock's view that the moral order is total and consistent proves to be limiting. The Restoration not only took its rise in the …

The Nonlinear Price Fynamics Of Us Equity Etfs, Gunduz Caginalp, Mark Desantis, Akin Sayrak

Economics Faculty Articles and Research

We investigate the price dynamics of large market-capitalization U.S. equity exchange-traded funds (ETFs) in order to uncover trader motivations and strategy. We show that prices of highly liquid ETFs can deviate significantly from their daily net asset values. By adjusting for changes in valuations, we report the impact of non-classical variables including price trend and volatility using data from 2008 to 2011. We find a cubic nonlinearity in the trend suggesting that traders are not only aware of the underreaction of others, but also self-optimize by anticipating others' reactions, and sell when the uptrend is stronger than usual.

The Effects Of Silicon Applications On Wear And Drought Stress Of Cool Season Turfgrass, Mike J. Badzmierowski, W. Michael Sullivan

Senior Honors Projects

The ability of turfgrass to maintain quality and functionality during use and drought stress are fundamental to almost all turfgrass environments. A possible mechanism to increase wear and drought tolerance is through the use of supplemental silicon (Si) application. Until recently, Si has received little attention for its role in crop physiology or performance.

While it is recoverable within the plant it is not recognized as an “essential” plant growth component. Si is the second most abundant element in the Earth’s crust; however the majority of soil-Si is bio-geochemically inert. Plants absorb Si exclusively as monosillicic acid, H₂SiO …

The North Atlantic Landscape Conservation Cooperative LCC (NA LCC) is a public-private partnership that provides information to support conservation decisions that may be affected by global climate change (GCC) and other threats. The NA LCC region extends from southeast Virginia to the Canadian Maritime Provinces. Within this region, the US National Climate Assessment documented increases in air temperature, total precipitation, frequency of heavy precipitation events, and rising sea level, and predicted more drastic changes. Here, we synthesize literature on the effects of GCC interacting with selected contaminant, nutrient, and environmental processes to adversely affect natural resources within this region. Using …

Geochemical Tracers Of Holocene Environmental Change Along The East Antarctic Margin, Natalie Romanoff

Theses, Dissertations and Culminating Projects

Marine sediment geochemistry targeting both organic and inorganic compounds can be used for the reconstruction of paleoenvironmental conditions. Part 1 of this study was a qualitative organic geochemical analysis implemented on sediment cores from the Antarctic Peninsula (AP) and East Antarctic Margin (EAM). Intervals of organic or diatomaceous rich sediment were analyzed by Pyrolysis-Gas Chromatography/Mass Spectroscopy (Py-GC/MS) with the goal of identifying soft-bodied algae responsible for elevated wt% carbon levels in horizons where diatoms are absent, and identifying the presence of methanogens in basins where cold seeps are likely to be present. The identification of biomarkers in Antarctic sediment was …

Making Dioramas Of Women Scientists Help Elementary Students Recognize Their Contributions, Jolene K. Teske, Phyllis Gray, Julie L. Klein, Audrey C. Rule

Curriculum & Instruction Faculty Publications

The STEM movement encourages girls to consider careers in science; however, for success, common misconceptions and biases need to be dispelled, while females’ spatial thinking skills are developed. All students, both girls and boys, need exposure to the accomplishments of women scientists to appreciate their contributions and to envision females as successful scientists. This one-week study conducted during a summer day camp examined upper elementary student (n = 15; 7 females, 8 males) attitudes toward science, women in science, and the possibility of a science career before and after participation in learning about diverse accomplished women scientists and making a …

Spatial Thinking In Planning Practice: An Introduction To Gis, Yiping Fang, Vivek Shandas, Eugenio Arriaga Cordero

PDXOpen: Open Educational Resources

The goals of this textbook are to help students acquire the technical skills of using software and managing a database, and develop research skills of collecting data, analyzing information and presenting results. We emphasize that the need to investigate the potential and practicality of GIS technologies in a typical planning setting and evaluate its possible applications. GIS may not be necessary (or useful) for every planning application, and we anticipate these readings to provide the necessary foundation for discerning its appropriate use. Therefore, this textbook attempts to facilitate spatial thinking focusing more on open-ended planning questions, which require judgment and …

Exploring Reading Comprehension In Undergraduate Students With Adhd Symptoms, Christine Shelton

USC Aiken Psychology Theses

Evidence suggests that Attention-deficit/hyperactivity disorder (ADHD) negatively affects verbal and reading comprehension in children, although the effect of ADHD on reading comprehension is partially mediated by the initial reading level of the participant. Additional research suggests that children and adults with ADHD tend to demonstrate a reduced working memory capacity, when compared to their non-ADHD peers, which may also affect the relationship between ADHD and reading comprehension. However, the current literature consists primarily of studies performed with children, and there has been little investigation into the biological factors of reading comprehension in ADHD populations. The current study sought to …

Data Transport System, Rahav Dor

All Computer Science and Engineering Research

To facilitate the WU Smart Home research [21] we built a system that collects data from sensors and uploads the data to the cloud. The system supports data collection from multiple locations (typically apartments) that are independent from each other, endowing the system with two benefit: distributed data collection and alleviating privacy concerns. Each location is managed by a local micro-server (μServer) that is responsible for receiving data packets from sensors and managing their transient storage. Periodically the μServer triggers a data transport process that moves the data to a cloud server where it is stored in a centralized database. …

Depauw Women During World War I: Female Citizenship And Higher Education In Early 20th Century America, Kristine Ruhl

Student Research

Women at DePauw University were propelled into positions of power on campus with the outbreak of World War I and America’s eventual entrance into the conflict. As male enlistment numbers rose, female students were forced to fill vacant jobs in organizations and clubs, as well as in the workforce. Working as educated people, the women at DePauw adjusted to the conflicting messages of the university and the government and developed their own understanding of what it meant to be a woman in World War I. Facing down widespread stereotypes, women pursued unparalleled positions of power during the war, thus, female …
