Bed Packing Models: Influence on Bed Geometry & Hydrodynamics
(2019-02-18)
Fixed Bed Reactors are multi-phase reactors where flow of gas, liquid or both phase reactants occurs over a packed bed of solid catalyst. These systems are common in industry as they are easy to construct, operate and ...
The Short-Term Skeletal and Dentoalveolar Effects of Overexpansion: A Randomized Controlled Trial
(2019-04-04)
The purpose of this study was to compare the skeletal and dentoalveolar effects of expansion in patients who are overexpanded (9-12 mm of RPE screw activation) with patients who are expanded conventionally (minimum of ...
A Strategic Analysis of Stationary Radiation Portal Monitors and Mobile Detection Systems in Border Monitoring
(2019-01-14)
Radiation Portal Monitors (RPM) are our primary border defense against nuclear smuggling, but are they still the best way to spend limited funds? The purpose of this research is to strategically compare RPM defense at the ...
Short-Term Freeway Traffic Prediction by Payne-Whitham Model Considering Driver’s Anticipation Effect
(2019-04-09)
In this research, we study a macroscopic traffic model, Payne-Whitham (PW) model, with an anticipation source term. The anticipation source describes how the traffic adjusts its speed based on the condition ahead. With the ...
Local Heating and Curing of Carbon Nanocomposite Adhesives Using Radio Frequencies
(2019-04-08)
In this thesis, the phenomenon of carbon nanoparticles producing a strong, rapid heating response in the presence of a radio-frequency electromagnetic field is explored, and this extremely selective heating property is ...
Evaluation of High Pressure / High Temperature, Eco-Friendly Iron Sulfide Scale Dissolver
(2018-10-22)
A high pressure, high temperature iron sulfide dissolver is not currently on the market. While a dissolver that meets these conditions needs to be developed, the corrosion rate of the dissolver, as well as the hydrogen ...
Spanish Language Use and Linguistic Attitudes in Laredo, Texas between 1860 and 1930
(2012-07-16)
This qualitative study investigated Spanish language use and linguistic attitudes in Laredo, Texas and the surrounding area from 1860 to 1930. In the public domain, sources include the Spanish and English language newspapers ...
Grounded Visual Analytics: A New Approach to Discovering Phenomena in Data at Scale
(2019-04-23)
We introduce Grounded Visual Analytics, a new method that integrates qualitative and quantitative approaches in order to help investigators discover patterns about human activity. Investigators who develop or study systems ...
Machine Learning Based Classification of Textual Stimuli to Promote Ideation in Bioinspired Design
(2013-08-09)
Bioinspired design uses biological systems to inspire engineering designs. One of bioinspired design’s challenges is identifying relevant information sources in biology for an engineering design task. Currently information ...
Examining the Perceptions of Pre-Service Teachers Enrolled in a Community College
(2019-03-12)
.
This multiple-article dissertation examined the perceptions of preservice teachers (PTs) enrolled at a community college. The first study was mixed-methods and examined the perceptions of PTs’ teaching efficacy at a ...
