This work analyzes the numerical curvature of buckling braces. An existing brace modeling learning tool, which in its current state allows users to change the inputs within a simulated model of a braced element, was modified to display the curvature diagram. The curvature diagram was verified through comparison to existing...
Traditional braced frames are an efficient and economic means of resisting seismic demands. However, braced frames are prone to story mechanisms, which can result in concentrations of demands and damage during seismic events. Including steel strongbacks in conjunction with traditional braced frames can mitigate story mechanisms. The SBF results in...
Thermodynamic properties of systems are often investigated computationally. Traditionally, thermal physics simulations are limited by their very small energy ranges and slow convergence. Broad histogram algorithms are a class of Monte Carlo algorithms that can explore an entire energy (and temperature) range in one thermal physics simulation: potentially saving months...
Introduction: Physical activity (PA) is recommended for all individuals because of the benefits it provides to physical health, mental health, and overall quality of life (QoL). It is also recommended for children with developmental disabilities (DDs), which make up about 15% of all U.S. children ages 3-17 years. Previous studies...
This thesis attempts to identify and develop a new narrative structure that has not yet been identified. This structure, which traces a character’s internal process of change throughout a work of literature, is known as the Awakening Arc. The Awakening Arc has seven stages that loosely correspond to Freytag’s external...
Reducing the CO2 emitted by the production of cement can greatly reduce the carbon emissions attributable to the built industry. By specifying concrete mixes with lower global warming potentials (GWPs), structural engineers can reduce the carbon emissions of concrete used in the built industry. This thesis uses a cradle-to-gate life...
The intent of this report is to provide a brief description of water quality issues in Nicaragua, Uganda and Bangladesh, and the technologies available to address these issues. The water quality parameters considered include: bacterial contamination, heavy metals and arsenic, pesticides and industrious chemicals, turbidity, radiological characteristics, and taste and...
The Colombian emerald deposits are globally unique because they are hosted in hydrothermally altered black shales on either side of the Cordillera Oriental. We used electron microprobe analysis to study variations in trace element concentrations in transects across emeralds, and used the ⁴⁰Ar/³⁹Ar dating method to determine the age of...
Following their extirpation due to the maritime fur trade, northern sea otter (Enhydra lutris kenyoni) reintroduction in the 1960s has facilitated their recolonization in southeast Alaska. Sea otters are now sympatric with wolves (Canis lupus), which are widespread in southeast Alaska, and a colonizing coyote population (Canis latrans). Recent studies...
