Risk Perception And Response Among International Students Of The University Of Southern Mississippi, Elida Lopes Souza Rocha

Master's Theses

Given the exposure of university campuses to hazards, disaster mitigation is a critical element of higher education policy. Although U.S. higher education institutions are leaders in the global education market, emergency warning systems give little consideration to how international students perceive risk, prepare for hazards, or access warning technologies available to them. This poses several questions regarding the suitability of hazards mitigation practices and the welfare of international students.

This thesis investigates the relationship between USM international students and natural hazards. Responses from online surveys and semi-structured interviews data were analyzed through qualitative and quantitative methods to document the extent …

Map-Gan: Unsupervised Learning Of Inverse Problems, Brandon S. Campanella

Master's Theses

In this paper we outline a novel method for training a generative adversarial network based denoising model from an exclusively corrupted and unpaired dataset of images. Our model can learn without clean data or corrupted image pairs, and instead only requires that the noise distribution is able to be expressed analytically and that the noise at each pixel is independent. We utilize maximum a posteriori estimation as the underlying solution framework, optimizing over the analytically expressed noise generating distribution as the likelihood and employ the GAN as the prior. We then evaluate our method on several popular datasets of varying …

Triangular Cosserat Point Element Method For Reducing Soft Tissue Artifact: Validation And Application To Gait, Jake Edward Deschamps, Stephen Klisch

Master's Theses

Human motion capture technology is a powerful tool for advancing the understanding of human motion biomechanics (Andriacchi and Alexander, 2000). This is most readily accomplished by applying retroreflective markers to a participant’s skin and tracking the position of the markers during motion. Skin and adipose tissue move independently of the underlying bone during motion creating error known as soft tissue artifact (STA), the primary source of error in human motion capture (Leardini et al., 2005).

(Solav et al., 2014) proposed and (Solav et al., 2015) expanded the triangular Cosserat point element (TCPE) method to reduce the effect of STA on …

Developing A Light Curve Simulation Tool For Ground And Space-Based Observations Of Spacecraft And Debris, Andrew T. Ochoa

Master's Theses

A light curve is a plot of brightness versus time of an object. Light curves are dependent on orbit, attitude, surface area, size, and shape of the observed object. Using light curve data, several analysis methods have been developed to derive these parameters. These parameters can be used for tracking orbital debris, monitoring satellite health, and determining the mission of an unknown spacecraft.

This paper discusses the development, verification, and utilization of a tool that simulates light curve data. This tool models ground-based observations, space-based observations, self-shadowing geometry, tumbling debris, and controlled spacecraft. The main output from the tool is …

An Analysis Of Camera Configurations And Depth Estimation Algorithms For Triple-Camera Computer Vision Systems, Jared Peter-Contesse

Master's Theses

The ability to accurately map and localize relevant objects surrounding a vehicle is an important task for autonomous vehicle systems. Currently, many of the environmental mapping approaches rely on the expensive LiDAR sensor. Researchers have been attempting to transition to cheaper sensors like the camera, but so far, the mapping accuracy of single-camera and dual-camera systems has not matched the accuracy of LiDAR systems.

A Multigrid Homotopy Method For Computing Eigenfunctions Of Differential Operators With Two-Dimensional Heterogeneity, Chelsea Drum

Master's Theses

In this thesis, we develop an accurate algorithm for computing the smallest eigenvalues of the self-adjoint spatial differential operator for the two-dimensional heat equation with a piecewise constant coefficient and periodic boundary conditions. The piecewise constant coefficient is created by the discontinuity of the diffusivity coefficient across the interfaces between two or more heterogeneous materials. Our method involves the combination of the well-known Inverse Iteration with a multigrid homotopy.

Privacy-Aware And Hardware-Based Accleration Authentication Scheme For Internet Of Drones, Tom Henson

Master's Theses

Drones are becoming increasingly present into today’s society through many different means such as outdoor sports, surveillance, delivery of goods etc. With such a rapid increase, a means of control and monitoring is needed as the drones become more interconnected and readily available. Thus, the idea of Internet of drones (IoD) is formed, an infrastructure in place to do those types of things. However, without an authentication system in place anyone could gain access or control to real time data to multiple drones within an area. This is a problem that I choose to tackle using a Field Programmable Gate …

Real-Time Prediction-Driven Dynamics Simulation To Mitigate Frame Time Variation, Mackinnon A. Buck

Master's Theses

Real-time physics engines have seen recent performance improvements through techniques like hardware acceleration and artificial intelligence. However, state of the art physics simulation technology fails to account for the variation in simulation complexity over time. Sudden increases in contact frequency between simulated bodies can momentarily increase the processing time per frame. To solve this, we present a prediction-driven real-time dynamics method that uses a memory-efficient graph-based state buffer to minimize the cost of mispredictions. This buffer, which is generated by a separate thread running the physics pipeline, allows physics computation to temporarily run slower than real-time without affecting the frame …

Plant Disease Detection Through Convolutional Neural Networks: A Survey Of Existing Literature, Best Practices, And Implementation, Kevin Label

Master's Theses

In the United States alone, common diseases spread among plants account for billions of dollars lost in crop yield each year. This issue is exacerbated in countries with less infrastructure to defend against crop epidemics, and can lead to famine and forced migration. Farmers can seek the help of plant pathology experts to defend against diseases and detect crop irregularities early on. However, access to experts can be difficult, and even those trained in the field may miss symptoms before it is too late. To assist in early disease detection, a number of papers have been released on the potential …

Estimating And Modeling Transpiration Of A Mountain Meadow Encroached By Conifers Using Sap Flow Measurements, Simon Joseph Marks

Master's Theses

Mountain meadows in the western USA are experiencing increased rates of conifer encroachment due to climate change and land management practices. Past research has focused on conifer removal as a meadow restoration strategy, but there has been limited work on conifer transpiration in a pre-restoration state. Meadow restoration by conifer removal has the primary goal of recovering sufficient growing season soil moisture necessary for endemic, herbaceous meadow vegetation. Therefore, conifer water use represents an important hydrologic output toward evaluating the efficacy of this active management approach. This study quantified and evaluated transpiration of encroached conifers in a mountain meadow using …

Aryl Halides As Potential Components For O-Aryl-N-(9'-Acridinyl)-Hydroxylamines Antitumor Agents, Erin Munder

Master's Theses

Acridine derivatives such as m-amsacrine (m-AMSA) are known to intercalate deoxyribonucleic acid (DNA). Their action targets the growth, function, and replication of cancer cells. Because of this, they are primarily used as anticancer and antimalaria drugs. Unfortunately, due to the low half-life m-AMSA possesses because of the ease of hydrolysis of the carbon 9-nitrogen bond (C9-N bond), large concentrations of the drug are needed to be pharmaceutically effective. This results in a large concentration of toxic aniline byproducts. To reduce the rate of hydrolysis but still maintain the binding to DNA, a modification to the m-AMSA structure was made. A …

Effects Of Nitrogen Management And Cultivar On Strawberry Production Under Disease Pressure, Kamille A. Garcia-Brucher

Master's Theses

Effects of nitrogen management and cultivar on strawberry production under disease pressure

Kamille Garcia-Brucher

California strawberry growers face increasing regulatory pressures to manage nitrogen (N) applications in their production system. Standard practice in the California strawberry industry is to apply a synthetic pre-plant controlled release fertilizer (CRF) to ensure the crop has sufficient N during winter establishment. Some research from the UC Cooperative Extension suggests this practice is not efficient at delivering N to the crop since most of the N is released from CRF before strawberry crop N uptake is significant. Another concern for California strawberry growers is loss …
