Artificial Olfactory System For Multi-Component Analysis Of Gas Mixtures., Alexander Aleksandrovich Larin Dec 2017

Artificial Olfactory System For Multi-Component Analysis Of Gas Mixtures., Alexander Aleksandrovich Larin

Electronic Theses and Dissertations

Gas analysis is an important part of our world and gas sensing technology is becoming more essential for various aspects of our life. A novel approach for gas mixture analysis by using portable gas chromatography in combination with an array of highly integrated and selective metal oxide (MOX) sensors has been studied. We developed a system with small size (7 x 13 x 16 inches), low power consumption (~10 W) and absence of special carrier gases designed for portable field analysis (assuming apriori calibration). Low ppb and even sub-ppb level of detection for some VOCs was achieved during the analysis …


Investigation Of Influential Factors On Selecting An Engineering Major., Paige A. Miller May 2017

Investigation Of Influential Factors On Selecting An Engineering Major., Paige A. Miller

Electronic Theses and Dissertations

This thesis evaluates the factors that freshman engineering students at the University of Louisville are taking into consideration when deciding on their major within engineering. The outcome of the research is expected to help to shape the syllabus of the ENGR 110 course, which is a mandatory class for all freshman engineering students. ENGR 110 is comprised of course lectures, department presentations, and company presentations. Currently, both the department and company presentations are held outside of course times. The influential factors identified by this research may help shape the course so that these factors are discussed thoroughly about each major …


Performance Analysis Of Organizations As Complex Systems., William C. Harrington Jr. May 2017

Performance Analysis Of Organizations As Complex Systems., William C. Harrington Jr.

Electronic Theses and Dissertations

This dissertation provides a method for evaluating the difference in performance after an organization makes a change while considering the stochastic nature in which it operates. A procedure that uses simulation to estimate outcomes by adjusting controllable parameters and leaving uncontrolled parameters unadjusted is proposed. As healthcare organizations are considered as highly complex systems, a case study involving a scheduling tactic change in the mother-baby service line of a hospital is used to demonstrate application of this procedure. The goal in the case study was to reduce delays in transitioning care of mother patients from the labor and delivery unit …


A Multi-Period Facility Location Model For Service Organizations Operating In A Competitive Environment., Sven W. Brose May 2017

A Multi-Period Facility Location Model For Service Organizations Operating In A Competitive Environment., Sven W. Brose

Electronic Theses and Dissertations

This thesis develops a multi-period, mathematical programming location model for facilities operating in a competitive environment. The objective is to maximize the profit in a variable demand environment. The solution of the problem can either be done in a robust or in a dynamic manner. A robust solution methodology forecasts the demand for all the periods in the planning horizon and provides a robust solution that may be suboptimal for any given period, but optimal when all the periods are taken into consideration. A problem with this approach is that it requires accurate forecast of demand for multiple periods into …


The Effect Of Role Assignment And Personality Subtypes In Simulation On Critical Thinking Development, Situation Awareness, And Perceived Self-Efficacy Of Nursing Baccalaureate Students., Dustin Travis Weiler May 2017

The Effect Of Role Assignment And Personality Subtypes In Simulation On Critical Thinking Development, Situation Awareness, And Perceived Self-Efficacy Of Nursing Baccalaureate Students., Dustin Travis Weiler

Electronic Theses and Dissertations

Previous studies have evaluated the effectiveness of high fidelity patient simulators (HFPS) on nursing training. However, a gap exists on the effects of role assignment and student personality subtypes in simulation scenarios. This thesis explored the effects of role assignment and personality on critical thinking, situation awareness, and self-efficacy in baccalaureate-level nursing students. Using researcher-developed tools and altering previously validated tools to fit the simulation scenario, the effects of role assignment and personality were determined. Role assignment and personality were found to have a significant effect on critical thinking and self-efficacy, but not situation awareness. It was determined that roles …
