Error Sensor Placement For Active Control Of An Axial Cooling Fan, Benjamin M. Shafer

Theses and Dissertations

Recent experimental achievements in active noise control (ANC) for cooling fans have used near-field error sensors whose locations are determined according to a theoretical condition of minimized sound power. A theoretical point source model, based on the condition previously stated, reveals the location of near-field pressure nulls that may be used to optimize error sensor placement. The actual locations of these near-field pressure nulls for both an axial cooling fan and a monopole loudspeaker were measured over a two-dimensional grid with a linear array of microphones. The achieved global attenuation for each case is measured over a hemisphere located in …

We carry out two searches for periodic gravitational waves using the most sensitive few hours of data from the second LIGO science run. Both searches exploit fully coherent matched filtering and cover wide areas of parameter space, an innovation over previous analyses which requires considerable algorithm development and computational power. The first search is targeted at isolated, previously unknown neutron stars, covers the entire sky in the frequency band 160-728.8 Hz, and assumes a frequency derivative of less than 4×10-10Hz/s. The second search targets the accreting neutron star in the low-mass x-ray binary Scorpius X-1 and covers the frequency bands …

"Questions About Stuff You Don't Normally See On A Map:" A Study Of Sixth-Graders' Abilities To Understand Quantitative Thematic Maps, Stephanie Lynn Gaspers

Dissertations and Theses

Middle school students work with many types of maps in school, however most maps they use are qualitative thematic maps that only show differences in kind as compared to quantitative thematic maps that show differences in amounts. This thesis investigates sixth-grade students' abilities to analyze three types of thematic maps: dot maps, choropleth maps, and graduated circle maps. Two hundred and two Oregon sixth-graders were tested on their abilities to interpret map symbology, make inferences from the data, categorize values into regions, and ask geographic questions concerning data distributions. The results indicate that students can understand these three quantitative thematic …

Method And Program Product For Determining A Radiance Field In An Optical Environment, Phillip N. Reinersman, Kendall L. Carder

USF Patents

A hybrid method is presented by which Monte Carlo techniques are combined with iterative relaxation techniques to solve the Radiative Transfer Equation in arbitrary one-, two- or three-dimensional optical environments. The optical environments are first divided into contiguous regions, or elements, with Monte Carlo techniques then being employed to determine the optical response function of each type of element. The elements are combined, and the iterative relaxation techniques are used to determine simultaneously the radiance field on the boundary and throughout the interior of the modeled environment. This hybrid model is capable of providing estimates of the under-water light field …

High Performance Quality Management Systems And Work-Related Outcomes: Exploring The Role Of Audit Readiness And Documented Procedures Effectiveness, Sean P. Goffnett

Master's Theses and Doctoral Dissertations

This study investigates a comprehensive quality management system (QMS) and its influence on multiple work-related outcomes. It examines certified quality systems used in the automotive industry to test whether QMS audit readiness mediates the relationship between quality factors and outcomes. A survey instrument, encompassing quality award criteria and system certification precepts, helped identify factors associated with high-performance. Regression results showed several factors, including leadership and process management, as being critically important in predicting work outcomes. Human resources emerged as being critical to most outcomes. Audit readiness did not emerge as a mediating variable, but rather as a significant process outcome. …
