Putting Making Into High School Computer Science Classrooms: Promoting Equity In Teaching And Learning With Electronic Textiles In Exploring Computer Science, Deborah A. Fields, Yasmin B. Kafai, Tomoko Nakajima, Joanna Goode, Jane Margolis

Instructional Technology and Learning Sciences Faculty Publications

Recent discussions of making have focused on developing out-of-school makerspaces and activities to provide more equitable and enriching learning opportunities for youth. Yet school classrooms present a unique opportunity to help broaden access, diversify representation, and deepen participation in making. In turning to classrooms, we want to understand the crucial practices that teachers employ in broadening and deepening access to making. In this paper, we investigate two high school teachers’ approaches in implementing a novel eight-week, electronic textiles unit within the Exploring Computer Science curriculum, where students designed wearable electronic textile projects with microcontrollers, sensors, and LEDs. We share teachers’ …

Application Of A Free-Surface Immersed Boundary-Lattice Boltzmann Modeling To Wave Forces Acting On A Breakwater, Badarch Ayurzana Mr, Hosoyamada Tokuzo Mr, Tungalagtamir Erdenebayar Mrs

International Symposium on Hydraulic Structures

A novel free surface immersed boundary-lattice Boltzmann method for wave–structure interaction and hydrodynamic force estimation is introduced. First, the proposed model is applied to incident wave propagation in a shallow water zone. The wave–breakwater interactions and wave forces on a breakwater are then analysed using the method. The results agreed with those of Goda’s formulae, confirming that the proposed model has a high potential for application to complex analysis of coastal engineering problems.

3d Numerical Modeling Of A Supercritical Intake With A Flow Diversion Barrier, L. Chang, S.N. Chan, Joseph H.W. Lee

International Symposium on Hydraulic Structures

The Hong Kong West Drainage Tunnel (HKWDT) system consists of 34 storm water intake structures designed to intercept storm water runoffs in upland catchments. During storm water events, each of these intake structures intercepts and diverts the upstream supercritical flow into a bottom rack chamber connected to a supercritical vortex drop. To satisfy the minimum environmental flow requirement in dry weather, small surface runoffs are intercepted by an inclined barrier across the main channel, and conveyed to the downstream drainage system through a 300mm wide low flow channel along one side of the intake. When the intakes are in operation …

Best Practices For Design Of Slurry Flow Distributions, José M. Adriasola, Robert H.A. Janssen

International Symposium on Hydraulic Structures

A critical structure in a modern mineral process plant is the slurry distribution box, that may receive inflows from different streams, and distributes the outflow to downstream unit operations in fixed proportions. The design of these structures is based on traditional hydraulic engineering considerations that apply to structures transporting or handling water. However, additional design considerations specific to slurries include settling of solid particles, the highly abrasive characteristics of the slurry and, occasionally, non-Newtonian rheology of the mixtures. For operational simplicity, and due to the abrasive nature of the slurry, orifices are principally used to distribute the flow. Lessons learned …

Performance Assessment Of Flow-3d And Xflow In The Numerical Modelling Of Fish-Bone Type Fishway Hydraulics, Su-Chin Chen, S.S. Tfwala

International Symposium on Hydraulic Structures

The advancement of computational power has afforded the resolving of more complex flows in three dimensional space. Several numerical codes have been developed and to single out which method to use is becoming a more complicated task. In this study we present two computational fluid dynamic (CFD) platforms, FLOW-3D and Xflow on 3D turbulent flows in a fish-bone type fishway. One of the basic yet most crucial step in a number of CFD codes is the creation of efficient computational meshes for real world applications. Regardless of the numerical method applied, the mesh quality will have pronounced effect on the …

Experimental Investigation Of Scour And Pressures On A Single Span Arch Bridge Under Inundation, Mohsen Ebrahimi, Recep Kahraman, Matthew Riella, Prakash Kripakaran, Slobodan Djordjević, Gavin Tabor, Dusan Prodanović, Scott Arthur

International Symposium on Hydraulic Structures

This paper presents two experiments, carried out in a 605mm-wide flume, to investigate scour and hydrodynamic pressure on a scaled model of a single span arch bridge. The geometry of the bridge model is scaled down according to a prototype bridge, with hydraulic conditions of the experiments representing a small river. Measured scour depths showed that flow vertical contraction by the arch bridge is higher than that of flat-deck bridges. Effect of a single cylindrical debris on scour was also evaluated and found to be negligible at the considered flow depth. Temporal variation of hydrodynamic pressure with scour evolution was …

The Numerical Simulation Of Steady And Unsteady Flows In Channel Networks Using An Extended Riemann Problem At The Junctions, Mohamed Elshobaki, Alessandro Valiani Associate Professor, Valerio Caleffi Assistant Professor

International Symposium on Hydraulic Structures

In this work, we perform an analysis of the numerical simulations of the channel flows in symmetrical and asymmetrical networks using the one dimensional shallow water equations (SWE). Inner boundary conditions must be imposed at the junction nodes and their numerical treatment is crucial to develop reliable mathematical models. Classical methods to provide the inner boundary conditions are extensively based on the energy and the momentum balances at the junction nodes. However, such methods suffer their empirical formulations based on experimental coefficients, which limit their applicability in practical applications (rivers flow, Dam flow) . As an alternative to such methods, …

Public Safety And Unauthorized Extreme Activities At Spillways, Steven L. Barfuss, Brian M. Crookston

International Symposium on Hydraulic Structures

One very important purpose for reservoirs is the recreational opportunities they provide to the general public. Unfortunately, some people engage in highly dangerous or extreme activities at dams and spillways that occasionally result in severe injury or death. In addition, some individuals purposely choose to ignore signage and safety fencing in order to access spillways and other hydraulic structures at the dam. Social media has become a means for advertising extreme activities that often occur on the physical structures at dams and spillways like surfing, wakeboarding, sledding, snowmobiling, skating, biking, diving, sliding, climbing, skateboarding, kayaking, wading and jumping. This only …

Using Combined Microgravity And Radiation To Simulate Skeletal Muscle Damage In Space, Lori Caldwell

Utah Space Grant Consortium

Muscular atrophy, defined as the loss of muscle tissue, is a serious issue for immobilized patients on Earth and in human spaceflight, where microgravity prevents normal muscle loading. Developing countermeasures for atrophy in spaceflight will require extensive screening of pharmaceuticals for efficacy, safety, contraindications, and dosage schedule. Due to the cost of spaceflight and limited crew time aboard the International Space Station, high throughput screening of pharmaceuticals under real microgravity conditions is not feasible. While traditional ground-based atrophy studies using the rodent hind-limb unloading model are effective at inducing physiological changes similar to spaceflight, they are not suited for first …

Thermal Transport To Droplets Impinging On Horizontal Superhydrophobic Surfaces, Jonathan Burnett

Utah Space Grant Consortium

An analytical model is developed to quantify the heat transfer to droplets impinging on heated superhydrophobic surfaces. Integral analysis is used to incorporate the apparent temperature jump at the superhydrophobic surface as a boundary condition. This model is combined with a fluid model which incorporates velocity slip to calculate the cooling effectiveness, a metric outlined in contemporary work. The effect of varying velocity slip and temperature jump is analyzed for different impact Weber numbers and surface temperature ranging from 60 to 100 degrees C. Heat transfer to the drop on superhydrophobic surfaces is decreased when compared to conventional surfaces.

Suspense Radio Series, Gothic Literature, And The American Family, Kelly Kirkham

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

My plan B thesis argues that the Suspense radio series, which aired from 1942-1963, served as a cathartic release for Americans during the Golden Age of Radio; the program accomplished catharsis by borrowing characteristics originating in 19th century gothic literature: sound effects, domestic space as setting, and the uncanny. The evidence I use in my argument includes radio show recordings, magazines, and published works from prominent radio scholars to analyze the effects of the Suspense program, specifically the 1960 season. Scholarly works include books and articles from Neil Verma, author of Theater of the Mind and assistant professor in Radio/Television/Film …

Confluence: A Braided Essay, Kathryn Christian

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Confluence: A Braided Essay seeks to examine three distinct topics: the trauma of my parents' divorce, the controversial decision over Bears Ears National Monument in southeastern Utah, and Aileen Wuornos, the first documented female serial killer in the United States. The braided essay's unique format allows the author to select three different topics and weave them together. As the author braids the strands through the essay, the implications of the strands arise and begin to vibrate together on the page. Confluence is a response to the rage of a serial killer, the pain of losing Bears Ears, and the angered …

Archaeological Analysis Of Bison Remains From Wilde Cave, Idaho, Michelle A. Platt

Undergraduate Honors Capstone Projects

Wilde cave is a lava tube located in Southeast Idaho on BLM lands. Recent investigations recovered a skeletal collection represented at least nine bison, as well as several other taxa. After many hours in the archaeology lab at Utah State University, identification of the collection shows the most prominent carcass parts represent fore and hind limbs, while vertebrae and ribs were least common. Also present was limited evidence of butchery-burning and cut marks-and carnivore modification on the skeletal collection. Given these observations, density mediated attrition and utility indices were used to better understanding the patterns in the archaeological bison bone. …

The Nfl And Trump: Did Protesting Cause The Decline?, Jameson Osmond

Undergraduate Honors Capstone Projects

This project is a study in econometric modeling of the effects of the protests of the national anthem in the NFL during the 2016-2017 seasons. The project is created to determine the accuracy or lack thereof of President Donald Trump's statement that the cause of the decline in viewership and ratings (and thus business) of NFL games was caused by protests that deterred US viewers.

Using viewership and rating data, along with various protest indexes created by collecting game-level protest data, an econometric model was constructed to allow for control over various endogenous and exogenous variables that surround NFL in-season …

Effect Of Wood Chips As A Component Of Soilless Media On Growth And Nutrition Of Food And Ornamental Crops, Kristen Bullough

Undergraduate Honors Capstone Projects

Peat is the central component of the soil-less media mix in all greenhouse crop production but it is expensive because it is harvested in Canada and shipped to greenhouses across North America. Wood chips provide a local, low-cost alternative to peat, but observations by growers indicate potential growth reductions from the addition of wood to peat-based media. Here I report the effects of the addition of wood chips to peat-based media. The study included four treatments: two controls (peat/vermiculite: 50/50 and 75/25) and two treatments with wood chips ' (peat/wood chips: 50/50 and 75/25) with three species (sunflowers, soybeans, and …

Designing A Synthetic Spider Silk-Based Coating For Urinary Catheters To Reduce The Risk Of Cautis, Alexander Cook

Undergraduate Honors Capstone Projects

Urinary and Intravenous (IV) catheters are two of the most commonly used medical devices for administering vital drugs and obtaining diagnostic samples from patients. Unfortunately, hospital acquired infections (HAIs) occur at alarming rates due to catheter usage. The aim of this project was to design a urinary catheter that would decrease the occurrence of these infections with a catheter coating that utilizes the antimicrobial properties of synthetic spider silk in combination with the antiseptic chlorhexidine. This synthetic spider silk catheter will introduce a novel approach to catheterization in the medical industry.

Undergraduate Honors Capstone Projects

This study investigated how Native Hawaiians and Hawai'i are represented by the media, specifically in movies and their accompanying trailers. Thirty movie trailers from movies released between 1939 and 2016 were analyzed. These movies represented the various movie genres of romantic comedy, thriller, war, animation, drama, historical, and more. The aim of the study was to compile evidence of various themes such as stereotyping, white-washing and language pronunciation within movie trailers in order to validate or extend conceptually the theoretical framework or theory about the lack of accurate representation of Native Hawaiians. This is a feasibility study that could help …

Affirmative Action Bans: Assessing Impacts In A Cross-State Context, Jacklyn M. Sullivan

Undergraduate Honors Capstone Projects

This paper builds on previous research on the effect affirmative action bans have on attendance rates for minorities at public and private universities. In total, nine states have implemented affirmative action bans between the present year and 1997. This paper analyzes data from the American Community Survey and provides an overview of related court cases and voter referendums to discuss this policy's effects. We find that affirmative action bans lead to an overall decrease in college attendance for minority students, most prominently seen in an attendance decrease for black students.

Young Women's Sexist Beliefs And Internalized Misogyny: Links With Psychosocial And Relational Functioning And Sociopolitical Behavior, Audrianna Dehlin

Undergraduate Honors Capstone Projects

Past literature has examined the impacts of sexism and its correlates. In this study, religious fundamentalism and relationship quality were identified as important factors related to sexist attitudes and internalize d misogyny. Two hundred ten women, ages 18-25, completed a survey including the Ambivalent Sexism Inventory, Revised Religious Fundamentalism Scale, Attitudes Toward Women Scale, Internalized Misogyny Scale, and Revised Dyadic Adjustment Scale. Higher religious fundamentalism was associated with lower relationship quality, mediated by internalized misogyny, traditional gender roles, and hostile sexism. While mental health outcomes were also collected, associations proved to be insignificant. The intersection of sexist attitudes and internalized …

Designing A Synthetic Spider Silk Based Coating For Urinary Catheters To Reduce The Risk Of Cautis, Tess Marie Armbrust

Undergraduate Honors Capstone Projects

Catheter associated urinary tract infections (CAUTis) are a leading cause of morbidity and mortality in patients with life-threatening conditions. Foley catheters are the most common catheter used when a patient requires hospitalization but can become burdened with microbes which lead to CAUTis, the most common source of hospital acquired infection (HAI). The attached bacteria can form biofilms on the catheter which are difficult to treat using oral antibiotics and can lead to chronic infections. Synthetic spider silk as a catheter coating shows great promise because of demonstrated strength, biocompatibility, and antimicrobial properties. In addition, the antiseptic chlorhexidine can enhance the …

Supplementation And Community Involvement As Drivers Of Salmon Recovery: Summer Chum Salmon (Oncorhynchus Keta) Populations In Union And Tahuya Rivers, Washington, United States, Seth M. Elsen

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Between the 1970s and late 1990s, Summer Chum salmon abundance in the Hood Canal basin declined significantly to the point the population was listed as “threatened” under the Endangered Species Act (1999), with multiple subpopulations extirpated. The Hood Canal Salmon Enhancement Group, in partnership with the Washington Department of Fish and Wildlife, developed and implemented a supplementation program to increase spawner abundance in the Union River so that supplementation could eventually take place in the Tahuya River, where Summer Chum had been extirpated. The program, which is only possible with intense volunteer efforts, reduced extinction risks for the Union River …
