Surface Water Hydrology Within The Great Salt Lake Basin, Madeline F. Merck

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt Lake (GSL) and its tributaries are ecologically and economically important resources for Utah. It is a highly saline lake, with salinity that is several times saltier than the ocean. Lake uses are heavily influenced by its salinity and lake level and, similarly, river uses by its streamflow quantity. Currently, the GSL Basin is experiencing changes that affect tributary inflows, lake level, and salinity. For my dissertation and in support of better lake management, I addressed important gaps in our understanding of the lake and the changes it is undergoing.

Investigating The Effects Of An Island, And A Speed Sign Gateway To Decrease Driver Speeding, Louai Al Shomaly

Masters Theses

There are thousands of motor vehicle crashes every year, and the yearly cost of crashes is estimated to be $430 billion dollars (National Highway Traffic Safety Administration). Twenty-eight percent of fatal related crashes in 2020 involve at least one driver speeding (CDC 2020). The application of a behavior analysis approach can be employed to reduce speeding and thereby decrease crashes. One way to reduce driver speeding behavior is the use of prompts. Van Houten and Van Houten (1987) and Van Houten et al. (2018) demonstrated the cost effectiveness approach of using prompts to decrease driver speeding at speed zones and …

Nonlinear Finite Element Model For Functionally Graded Porous Circular/Annular Micro-Plates Under Thermal And Mechanical Load, Enrique Nava Munoz

Masters Theses

A nonlinear finite element model for micro circular/annular plates under thermal and mechanical loading is developed using a third order shear deformation theory. In the kinematic assumptions, the change of plate thickness is allowed and no transverse shear strains are considered on the top and bottom surfaces. A power-law distribution is utilized to account for variations of two constituents through the thickness of the plate. Three different types of porosity distributions are considered. The strain gradient effect in micro scale structures is considered using the modified couple stress theory. The dynamic version of the principle of virtual displacements is used …

Exploring Social Hierarchy Computationally To Further Our Understanding Of Social Organizations Within Their Environments, Stanley L. Rhodes Jr.

All Graduate Theses and Dissertations, Fall 2023 to Present

Hierarchy is ever-present across countless human societies, a seemingly inescapable reality of small organizations and national governments. However, there is a lot about hierarchy we don’t understand, and if we want to make better organizations and better society, it is crucial we learn more about it. This dissertation investigates three questions: 1) “What is hierarchy?” 2) “How is hierarchy useful?” 3) “How does hierarchy vary?” I find that social scientists do not all mean the same thing by hierarchy, even within the same fields; yet, they do consistently write of hierarchy as control (like boss-employee relations), hierarchy as rank (like …

Forecasting Traffic Speed During Daytime From Google Street View Images Using Deep Learning, Junfeng Jiao, Huihai Wang

Research Collection College of Integrative Studies

Traffic forecasting plays an important role in urban planning. Deep learning methods outperform traditional traffic flow forecasting models because of their ability to capture spatiotemporal characteristics of traffic conditions. However, these methods require high-quality historical traffic data, which can be both difficult to acquire and non-comprehensive, making it hard to predict traffic flows at the city scale. To resolve this problem, we implemented a deep learning method, SceneGCN, to forecast traffic speed at the city scale. The model involves two steps: firstly, scene features are extracted from Google Street View (GSV) images for each road segment using pretrained Resnet18 models. …

Gpu Based Monte Carlo Estimation Of Eddy Current Losses In Electromagnetic Coil-Core System, Adwaith Ravichandran

Theses and Dissertations

A novel parallelizable probabilistic approach to model eddy currents in AC electromagnets is presented in this research. Consequently, power loss associated with the formation of these eddy currents is estimated and validated using experimental data. Furthermore, predicting the effect of ferromagnetic alternating field enhancement on power loss in the source excitation winding has been an active area of research. Unlike a stationary field, an alternating sinusoidal field diffuses partially into the ferromagnetic material leading to a predictably sub-optimal field enhancement. To model these physics, finite element techniques employ nonlinear iterative solvers which are time consuming. A novel method is developed …
