The Economics And Viability Of Organic Forage And Grain Production In Utah, Mackenzie Lee

All Graduate Reports and Creative Projects, Fall 2023 to Present

Utah farmers face significant financial and agronomic challenges when transitioning into organic forage and grain production. The state’s high-desert climate, alkaline soils, and limited irrigation water make organic production more expensive and riskier than in many other regions.

This study evaluates a ten-year rotation built around alfalfa, which acts as a natural nitrogen engine for the system. Because alfalfa fixes large amounts of nitrogen, it reduces fertilizer costs for later crops such as organic corn. However, farmers must first survive the three-year transition period, during which they must follow organic rules but cannot sell their crops at organic prices.

Using …

Improving Tensorsketch Using Complex Random Variables, Amit Sharma, Mohammad Azhar Khan, Rameshwar Pratap, Keegan Kang

Faculty Conference Papers and Presentations

TensorSketch by Pham and Pagh [2013], Kar and Karnick [2012] provides efficient sketching algorithms for highdimensional polynomial kernels $\vec{x}^{\otimes p} \in \R^{d^p}$. Kar and Karnick [2012] uses dense Johnson-Lindenstrauss (JL)-type projections with computational cost $O(pDd)$, whereas Pham and Pagh [2013] extends the sparse CountSketch [Charikar et al., 2024] algorithm, yielding a faster algorithm for high-dimensional sparse inputs with running time $O\left(p(\nnz{\vec{x}} + D \log D)\right)$. However, the variance of both estimators grows exponentially with the polynomial degree $p$, scaling as $3^{p}/D$, where $D$ denotes the sketch dimension. Recent work by Wacker et al. [2023] showed that using complex-valued distribution reduces …

Racialised Gradients Of Human Value And Marx’S Working Day, Today, Anthony F. Peressini

Philosophy Faculty Research and Publications

This paper reconsiders the ‘working day’ discussion in chapter ten of Capital and how it centres two parameters in the generation and appropriation of surplus value. The first parameter is the cost of labour-power paid by the capitalist and the second is the time that the worker must yield to the capitalist: the ‘length of the working day’. The first parameter represents the amount of pay required to keep the worker alive and able to work. Marx understood it as a lower limit below which capitalism would cease to function. This paper argues that, while analytically coherent, this understanding of …

Dbssnet: Dual-Branch Spectral-Spatial Network With Data-Driven And Knowledge-Guided Band Selection For Uav Hyperspectral Wheat Rust Detection, Subin Kim

All Graduate Theses and Dissertations, Fall 2023 to Present

Wheat rust is a serious plant disease that can reduce crop yield and quality. In practice, the disease is often noticed only after visible symptoms appear, when some damage may already be difficult to reverse. This thesis studies whether drone-based imaging can help detect wheat rust earlier and more reliably in field environments. 

Unlike an ordinary color photograph, a hyperspectral image records reflected light at many narrow wavelengths. These measurements can reveal useful information about plant condition, but they are also high dimensional, noisy, and difficult to analyze when only a limited number of labeled field samples are available. To …

Mining Time Series Shapelets And Association Rules For Solar Flare Prediction, Drew Watson

A Multi-Label Computer Vision-Based Approach For Condition Assessment Of Traffic Signs: Database Compilation, Model Training, And Evaluation, Shailaja Ratna Pandey

All Graduate Theses and Dissertations, Fall 2023 to Present

Traffic signs help drivers and pedestrians to understand roadway rules, warnings, and directions, which determine how road users should behave. When signs fade or delaminate, they become harder to read and interpret, which creates increased safety hazards. Transportation agencies usually deploy engineers to the field to inspect signs because they need to evaluate and document the sign’s condition based on established standards and engineering judgment. This process requires substantial time and cost and becomes challenging to apply across large highway networks.

This study evaluated two computer vision (CV) models for automated traffic sign condition assessment using highway images collected across …
