Remote Vibration Based Monitoring Of Bridge Scour, Alan Kazemian

Dissertations

The gradual erosion of the sediment around a bridge foundation is called Scour. This erosion is caused by water flow and increases during times of high-water flow such as flooding. The scour leaves the bridges structurally unsound over time and jeopardizes the safety of the structure. Approximately 60 percent of bridge failures in the United States are caused by scour. A variety of types of devices have been used to detect scour. Most of these devices only observe the scour and not the structural integrity of the bridge. The typical approach has relied on visual inspections of the bridges after …

A Brief Self-Compassion Intervention For Survivors Of Sexual Trauma With Psychological Distress, Natalie Marie Hogue

Dissertations

Individuals who have experienced sexual trauma are at an increased risk of psychological disorders and psychological distress (Dworkin, 2020; Dworkin et al., 2017; Dworkin & Schumacher, 2018). Sexual trauma has one of the highest conditional risks for the development of posttraumatic stress disorder (Domino et al., 2020; Perrin et al., 2014). Experiential avoidance, shame, and posttraumatic cognitions are associated with psychological distress after experiencing sexual trauma (Bhuptani et al., 2019; Domino et al., 2020; Foa et al., 1999; Merwin et al., 2009). Established research suggests that self-compassion-based therapies can be effective in reducing psychological distress and treating a wide range …

On Near-Linear Cellular Automata Over Near Spaces, Abdul-Rahman M. Nasser

Dissertations

Cellular Automata can be considered as examples of massively parallel machines. They are computational mathematical objects consisting of a grid of cells, each of which can exist in a finite number of states. These cells evolve over discrete time steps according to a set of predefined rules based on the states of neighboring cells. The notion of cellular automata was first introduced by Ulam and von Neumann and then popularized by John H. Conway in the 1970s with one of the most famous examples being The Game of Life.

This research builds on and generalizes the work of Tullio Ceccherini-Silberstein …

A Contingency Table Alternative To Poisson Regression In Comparing The Frequency Distributions Of Two Populations, Sandra Tay

Dissertations

When testing the conditional independence between a binary outcome and a binary treatment indicator, conditioned on a categorical variable with k levels, typically represented by a K × 2 frequency table, researchers often turn to Poisson regression and the Cochran-Mantel-Haenszel (CMH) test. However, a common challenge encountered in these analyses is the presence of treatment effect heterogeneity. Introducing an interaction term between treatment indicators and effect modifiers in log-linear regression offers potential solutions, yet the equidispersion assumption of Poisson regression remains problematic. On the other hand, the CMH test assumes similar treatment effects across all strata, disregarding potential variations among …

Macroevolution Meets Community Ecology: Does Species Interaction Influence Tempo And Mode Of Diversification In Fishes That Cross The Marine/Freshwater Boundary?, Victor De Brito

Dissertations

Evolutionary transitions between marine and freshwater ecosystems are an extreme ecological shift and expose fish lineages to novel abiotic and biotic settings. Yet, it remains unclear how those habitat transitions and the interaction with the newly invaded communities have altered the macroevolutionary dynamics of fish clades. The theory of ecological opportunity predicts that lineages that colonize species-poor regions will have greater potential for phenotypic diversification and speciation than lineages invading species-rich regions. Thus, transitions between marine and freshwaters in depauperate regions may promote adaptive radiation. While most major fish clades are restricted to either marine or freshwaters, so called transmarine/ …

The Synthesis, Characterization, And Application Of Polysaccharide-Based Additive To Improve Wet And Dry Strength And High-Barrier Properties Of Paper Products, Cornellius Marcello

Dissertations

Paper products play an essential role in our daily lives owing to their low cost, environment-friendly character, renewability, and recyclability. Paper manufacturers have been using petroleum-based strength additives (cPAM, GPAM, PAE) to meet the perceived needs of customers. On the other hand, paper produced from cellulose is hydrophilic and porous, leading to shallow water and grease resistance, causing paper manufacturers to use many kinds of coating materials such as poly-fluoroalkyl substances (PFAS) and synthetic plastic to improve water resistance, especially for food packaging paper products like cups, plates, food boxes, and packaging. However, PFAS are identified as likely carcinogenic to …
