Time Series Deep Learning Approach For The Intermittent Operational Performance Of A Wellhead Water Treatment And Desalination System, Michael G. Clement

Electronic Theses, Projects, and Dissertations

Distributed water treatment and desalination (DWTD) systems are becoming significant for serving disadvantaged communities that are geographically segregated from centralized water distribution networks. However, given the remote nature of the communities, these systems must operate autonomously adapting to intermittent operations due to varying water use patterns and unavailability of continuous manual labor support. Machine Learning models describing and forecasting system performance are critical, allowing for model-based control, performance forecasting, fault detection, and determination of causal relationships among process attributes. Accordingly, graph convolutional neural networks with an attention mechanism (GATConv) were developed to describe the intermittent operational profiles of a wellhead …

Advancing Snow Water Equivalent Monitoring With Machine Learning And L-Band Interferometric Synthetic Aperture Radar (Insar) Data, Ibrahim Olalekan Alabi

Boise State University Theses and Dissertations

Seasonal snow is a critical freshwater resource for an estimated 2 billion people worldwide. Yet, accurately measuring the amount of water sitting in a snowpack, referred to as snow water equivalent (SWE), over large, often mountainous regions has posed a long-standing challenge. Ground-based measurements of SWE are precise but sparse, while remote sensing techniques like passive microwave sensors struggle with coarse resolution and signal saturation in deep snow. Due to the challenges of direct SWE measurement, snow depth has emerged as an alternative pathway to SWE estimation. SWE is strongly correlated with snow depth, and by leveraging this relationship, we …

A Multi-Tiered Approach To Improving Vaccination: Adjuvanticity, Alternate Routes Of Delivery, And Science Communication, Haley Agnes Bridgewater

Boise State University Theses and Dissertations

Vaccines have been used to prevent infectious disease for over 200 years. While they are an incredible way to prevent loss of life, they can be improved upon. Researchers around the globe are working to improve the immune response and ultimately the protection provided by existing and new vaccines. In this dissertation, I investigate three ways to improve vaccine immune responses: using an adjuvant, using a prime-boost intramammary delivery route in cows, and using microneedle delivery route.

Reproducible Infrastructure For Modeling Thermoplastic Polymer Fusion Welding, Chris D. Jones

Boise State University Theses and Dissertations

Aircraft materials must balance the demands of being light-weight and fuel efficient with being safe, durable, and strong. Carbon-fiber reinforced polymer composites are able to meet both of these requirements, and as a result, they are being utilized more and more in aircraft manufacturing. Thermoset polymers are typically used as the matrix material in these composites; however, thermoset polymers require long curing times in large autoclave ovens in order to form chemical cross-links, which once present, cannot be melted upon further heating. As a result, joining smaller thermoset composite parts together to build larger structures requires using mechanical fasteners, which …

Development And Application Of Computational Tools For Organic Molecular Structure Prediction From Small Molecule Crystal Structure Determination To Polymer Persistence Length, Madilyn E. Paul

Boise State University Theses and Dissertations

This dissertation utilized two areas of computational simulations for organic molecular structure prediction. First, we investigate the possible polymorphism of both barbituric acid dihydrate (BTADH) and violuric acid monohydrate (VAMH) using density functional theory. Crystalline structures that exhibit polymorphism have an increased level of uncertainty in predicting their chemical and physical properties. BTADH was previously thought to undergo a subtle phase transition from P2₁/n to planar Pnma at 217 K. We conclude that barbituric acid dihydrate exhibits crystalline disorder in which the molecules are crystallized in a non-merohedrally twinned P2₁/n configuration below …

Logic's Modern British Up-Enders, Defenders, And Extenders: Whately's Revitalization Of Logic, Calvin Jongsma

Faculty Work Comprehensive List

Logic developed dramatically during the last half of the nineteenth century. The baseline for these transformations in Great Britain was the revival of logic by Richard Whately around 1825. Whately successfully defended syllogistic logic as the science of valid reasoning against potent seventeenth and eighteenth-century detractors—Bacon, Locke, Reid, Campbell, Stewart, and others. In so doing, he made logic an intellectually respectable field of investigation for the next generation of logicians to explore and extend. This included John Stuart Mill (inductive logic), Augustus De Morgan (logic of relations), and George Boole (algebraic logic; propositional logic).

It also is involved in human reproduction, modulation of T cell activation and immunoinflammatory effector functions, autophagy, and the newly identified intracellular complement system (complosome). CD46 is also known as a "pathogen" magnet, being a port of entry for at least seven bacteria and five viruses. Moreover, CD46 has recently emerged as a key player in cancer …

Strategies For Increasing Methane Removal In Methanotroph Bench-Scale Systems For The Production Of Ectoine, Jaden Storrer

All Graduate Theses and Dissertations, Fall 2023 to Present

Anthropogenic methane emissions contribute to the greenhouse gas profile which is the chief cause of climate change. One significant source of methane emissions is biogas produced from bacteria in wastewater facilities and landfills. Methane rich biogas has the potential to be valorized into high value bioproducts by using methanotrophs (microbes that use methane as their primary carbon source). Methylotuvimicrobium alcaliphilum 20Z was selected for this study as it can generate ectoine when grown in highly saline environments. Ectoine has been proven to have many benefits such as it prevents protein denaturation, it has hydration properties, and is a UV protectant. …

Investigating Changes In Hydroclimate, Land Cover, And Evapotranspiration Across The Great Salt Lake Basin And Its Major Subbasins, Bhuwan Ghimire

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt Lake (GSL) is a lake of environmental and economic importance for Utah, and in recent years lake levels have declined to critically low levels. The lake level is dependent on the balance between the inflow and outflow. Inflow into the lake is governed primarily by the streamflow originating from the Bear, Weber and Jordan River basins (GSL subbasins), direct precipitation over the lake and groundwater entering into the lake. The GSL is a terminal lake, with outflow via evaporation from the lake.

In this study, we examined hydrologic processes within the river basins that relate to streamflow …

A Laboratory Study Of Local Scour And Driftwood Effects At A Type A Piano Key Weir, Manisha Panthi

All Graduate Theses and Dissertations, Fall 2023 to Present

Piano key weirs are a unique weir designed to increase the amount of flow that passes over it via its zig-zag shape (similar to the rectangular shape of keys of a piano). With its relatively small footprint, they are becoming more popular to upgrade existing water management projects and are also being used in new construction works. However, there is little information available regarding how these weirs handle sediment and driftwood.
