Using Remote Sensing Data Fusion Modeling To Track Seasonal Snow Cover In A Mountain Watershed, Allison N. Vincent May 2021

Using Remote Sensing Data Fusion Modeling To Track Seasonal Snow Cover In A Mountain Watershed, Allison N. Vincent

Boise State University Theses and Dissertations

Seasonal snowfall is the largest component of the water budget in many mountain headwater regions around the world. In addition to sustaining biological water needs in drier, lower elevation areas throughout the year, mountain snowpack also provides essential water inputs to the Critical Zone (CZ) - the outer layer of the Earth’s surface, which hosts a variety of biogeochemical processes responsible for transforming inorganic matter into forms usable for life. Water is a known driver of CZ activity, but uncertainty exists in its spatial and temporal interactions with CZ processes, particularly in the complex terrain of heterogeneous mountain areas. Increasing …


Assessing Soil-Related Terroir Factors In Sunnyslope District Vineyards Of Southwest Idaho, Rachael Nicole Haggen May 2021

Assessing Soil-Related Terroir Factors In Sunnyslope District Vineyards Of Southwest Idaho, Rachael Nicole Haggen

Boise State University Theses and Dissertations

Terroir is the set of factors including climate, soil, and management practices that influence the character of a wine. Of these factors, soil texture and chemistry is a major determinant in wine grape quality (van Leeuwen et al., 2009). Understanding the characteristics of the soil is key to making decisions that support the production of the highest possible quality grapes from the resources available. Few studies have been conducted in the Snake River Valley AVA (SRVAVA). This study seeks to build upon the data already available and provide analysis of vineyard-scale terroir in a leading grape growing district of the …


Whey Protein Powder Analysis By Kjeldahl And Mid-Infrared Spectroscopy, Rose Saxton May 2021

Whey Protein Powder Analysis By Kjeldahl And Mid-Infrared Spectroscopy, Rose Saxton

Boise State University Theses and Dissertations

There is an ever-expanding number of high protein dietary supplements marketed as beneficial to athletes, body builders, infant formulas, elder care, and animal feed. Consumers will pay more for products with high protein per serving data on their nutritional labels, making the accurate reporting of protein content critical to customer confidence. The Kjeldahl Method (KM) is the industry standard to quantitate dairy proteins, but the result is based on nitrogen content, which is an approximation of nitrogen attributable to protein in milk. Optical spectroscopy is commonly used for quality control measurements and has been identified as having the potential to …


Exploring The Beginnings Of Algebraic K-Theory, Sarah Schott May 2021

Exploring The Beginnings Of Algebraic K-Theory, Sarah Schott

Boise State University Theses and Dissertations

According to Atiyah, K-theory is that part of linear algebra that studies additive or abelian properties (e.g. the determinant). Because linear algebra, and its extensions to linear analysis, is ubiquitous in mathematics, K-theory has turned out to be useful and relevant in most branches of mathematics. Let R be a ring. One defines K0(R) as the free abelian group whose basis are the finitely generated projective R-modules with the added relation PQ = P + Q. The purpose of this thesis is to study simple settings of the K-theory for rings and …


A Data Adaptive Model For Retail Sales Of Electricity, Johanna Marcelia May 2021

A Data Adaptive Model For Retail Sales Of Electricity, Johanna Marcelia

Boise State University Theses and Dissertations

When fitting a model to a data set, the goal is to create a model that captures the trends present in the data. However, data often contains regions where the underlying model changes or exhibits shifts in certain parameters due to economic events. These locations in the data are known as changepoints, and ignoring them can result in high error and incorrect forecasts. By developing a specific cost function and optimizing using the genetic algorithm, we are able to locate and account for the changepoints in a given data set. We specifically apply this process to the retail sales of …


Zariski Geometries And Quantum Mechanics, Milan Zanussi May 2021

Zariski Geometries And Quantum Mechanics, Milan Zanussi

Boise State University Theses and Dissertations

Model theory is the study of mathematical structures in terms of the logical relationships they define between their constituent objects. The logical relationships defined by these structures can be used to define topologies on the underlying sets. These topological structures will serve as a generalization of the notion of the Zariski topology from classical algebraic geometry. We will adapt properties and theorems from classical algebraic geometry to our topological structure setting. We will isolate a specific class of structures, called Zariski geometries, and demonstrate the main classification theorem of such structures. We will construct some Zariski structures where the classification …


New Applications For The Kinetic Exclusion Assay (Kinexa), Mark Harrison Smith May 2021

New Applications For The Kinetic Exclusion Assay (Kinexa), Mark Harrison Smith

Boise State University Theses and Dissertations

This dissertation examines the fundamental principles and applicability of the kinetic exclusion assay (KinExA), developed and marketed by Sapidyne Instruments of Boise, Idaho, since 1995. Chapter One reviews and consolidates the manufacturer’s guidance and many early papers that delineate the practical and theoretical aspects of the technology. In brief, KinExA is a two stage analytical system. In stage one, a number of solutions are prepared, whereby one of the partners is kept constant (the constant binding partner, or CBP), while the other (the titrant) is varied, usually in serial dilution. As the titrant is increased, the free CBP decreases, and …


Ensuring Consistency And Efficiency Of The Incremental Unit Network In A Distributed Architecture, Mir Tahsin Imtiaz May 2021

Ensuring Consistency And Efficiency Of The Incremental Unit Network In A Distributed Architecture, Mir Tahsin Imtiaz

Boise State University Theses and Dissertations

An incremental system takes advantage of upcoming data as early as possible. In other words, an incremental system processes received data incrementally. Incremental systems can be useful over non-incremental systems to build spoken dialog systems when we are looking for faster and more human-like behavior. For example, human-to-human conversations are incremental, as a listener does not wait for a speaker to finish speaking to begin understanding. Inspired by the fact that Robot-Ready Spoken Dialog Systems must be incremental and need to work distributedly, and IU framework "breaks" in a distributed architecture, I attempted to use the IU network to fulfill …
