The Effect Of Active And Passive Control On Air Traffic Controller Dynamic Memory, Esa M. Rantanen

Master's Theses - Daytona Beach

The purpose of this study was to investigate the effect of automated and passive control on air traffic controller dynamic memory. The study consisted of two experiments, each involving a realistic ATC scenario for radar approach control with a mix of arriving and departing traffic. In Experiment I, the subjects performed manual control of the traffic while, in Experiment II, the scenario was highly automated and the subjects were tasked with only monitoring the situation. The dynamic memory performance was measured by interrupting the scenario and having the subjects recall the traffic situation at the moment of simulation interruption. The …

Comparison Of Air Traffic Control Candidate Ability With Simulator-Based Training Measures, Lawrence A. Tomaskovic

Master's Theses - Daytona Beach

The purpose of this study was to determine if the utilization of an experimental computer-based selection test battery would aid in the prediction of a candidates performance when using an air traffic control computer-based simulation program. Each candidate completed the selection test battery, and then received air traffic control instruction using the air traffic control simulation program incorporated in the TRACON/Pro™ simulator system.

Numerical Analysis Of One-Dimensional Waves In Generalized Thermoelasticity, Mark J. Gorman

Theses

Classical thermoelasticity theory is based on Fourier's Law of heat conduction, which, when combined with the other fundamental field equations, leads to coupled hyperbolic-parabolic governing equations. These equations imply that thermal effects are to be felt instantaneously, far away from the external thermomechanieal load. Therefore, this theory admits infinite speeds of propagation of thermoelastic disturbances. This paradox becomes especially evident in problems involving very short time intervals, or high rates. of heat flux. Since infinite wave speeds are physically unrealistic in some situations, and since experiments have shown the existence of wavetype thermoelastic interactions, like in the observation of thermal …

Siblingship In Afro-Caribbean Kinship: The Garifuna Of Belize, Kenneth M. Robey

Anthropology ETDs

This dissertation examines siblingship in the Garifuna village of Hopkins, an Afro-Amerindian community in southern Belize. It is based on intensive interviews with individual informants and comprehensive genealogical and demographic data that I collected during fieldwork there in 1987-89.

In this study, I describe variations of Garifuna siblingship and changes in siblingship over time. I consider relationships between individual siblings and investigate sibling groups acting in solidarity or disunion towards other Garifuna social units and the outside world. I evaluate sibling interdependencies from childhood to old age in ordinary affairs and at times of crisis. In addition to looking at …

Atmospheric Hydrocarbon Analysis, Dawei Han

Dissertations and Theses

This treatise studied two correlated important issues in atmospheric chemistry: real-time monitoring of ambient air and removal mechanisms of atmospheric hydrocarbons. An analytical system was designed for the purpose of identification and measurement of sub-ppb level hydrocarbons of different reactivities in air samples. This analytical system was then applied to a series of smog-chamber studies which simulated the removal of reactive hydrocarbons from the atmosphere by reaction with hydroxyl radicals. Six representative atmospheric hydrocarbons (hexane, octane, toluene, m-xylene, a-xylene and mesitylene) were selected for these experiments. The experimental data indicated that the decay of atmospheric hydrocarbons under laboratory conditions is …

Ethnic Identity Changes Among Hong Kong Chinese Americans, Pui-Lam Lo

Dissertations and Theses

During the last ten years, the number of Hong Kong Chinese migrating to the U.S. has increased. These new immigrants, with knowledge and life experiences shaped by the urban metropolis of Hong Kong, have begun to influence different aspects of Chinese communities in U.S. cities. A study of this group of Hong Kong Chinese provides a better understanding of how they have adapted to their new environment and how they have come to recognize themselves as Hong Kong Chinese Americans. In reviewing the available literature, very few studies have dealt with the identity changes of this group of people. Hence, …

United States-Afghanistan Diplomatic Relations, September-December 1979: Hafizullah Amin's Struggle For Survival, Shaista Wahab

Student Work

During the 19th and early 20th centuries Afghanistan remained a buffer zone between Czarist Russia and British India. The struggle between these two powers to control the region or at least to deny such a control to their rival was called "The Great Game." When the Soviets invaded Afghanistan on December 27, 1979, the U.S. Charge d'Affaires in Kabul wrote in a telegram addressed to Washington "...the Great Game is over." The Soviet invasion of Afghanistan was the most recent Russian ambitious act to extend their control beyond their southern border. The Soviet control over Afghanistan lasted for more than …

Sectional Voting Cleavages In Nebraska Presidential Elections, 1892-1992, Robert H. Watrel

Student Work

This thesis examines the spatial and the temporal aspects of presidential sectionalism in Nebraska between 1892-1992. The Democratic percentages of the total vote for president are computed in each county in each election between 1892 and 1992. These data are then subjected to T-mode and S-mode factor analysis. The T-mode factor analysis is used to identify electoral epochs, which helps to explain the changing geographical pattern of support for presidential elections in Nebraska. The S-mode factor analysis is used to identify electoral regions, which helps locate sectional partisan support. The result of the T-mode factor analysis revealed four "factors" or …

The Last Dress Rehearsal: A Critical Study Of The Production And Censorship Of The Federal Theatre Project's, Ethiopia (1936), Michael Joseph Mccandless

Student Work

In January, 1936, Ethiopia, a play which is dramatized by the events leading up to the Italo-Ethiopian War, was scheduled to open in New York. It was to be the first in a series of “living newspaper” plays funded by the Federal Government under the auspices of the Federal Theater Project, a preforming arts branch of President Franklin Roosevelt’s Works Progress Administration. The opening night, however, never came as the production was canceled by Administration officials who publicly stated that foreign heads of state could not be depicted on stage in federally-funded production. This thesis attempts to determine the reasons …

The Mode Of Action Of Intersex In Terminal Sexual Differentiation In Drosophila., Robert Russel Risley

Student Work

The intersex gene (2-60.5) lies at the terminus of the regulatory pathway that determines sex-type in Drosophila. Its product functions with the female-specific product of doublesex, another gene in the self-determination regulatory pathway, to regulate female-specific differentiation. However, the mechanism of this regulation has not been clearly demonstrated. Using a temperature-sensitive allele at intersex to eliminate its function at time points both during development and in the adult stage, the mode by which intersex regulates female determination was addressed. When chromosomal females bearing a temperature-sensitive intersex allele are raised at a permissive temperature, they develop as phenotypic females. Animals raised …

An Exploratory Examination Of The Interrelationships Among Parenting Beliefs, Parenting Stress, And Parenting-Child Interaction In The Context Of Maternal Polydrug Addiction And Prenatal Drug Exposure, Darlene Grant

Doctoral Dissertations

The focus in this dissertation was on the interrelationships among parenting beliefs, parenting stress, and parent-child interaction. It was hypothesized that mothers' addiction status moderated these interrelationships when controlling for the effects of income, levels of education, race, age, number of children, and child's prematurity status.

Data from a program evaluation of a residential addiction treatment program and comparison data from five day care centers were collected from August 1991 to August 1993 using the Adult-Adolescent Parenting Inventory, the Parenting Stress Index, and the Parent-Child Interaction Form. The sample included 39 polydrug-addicted and 31 non-drug-addicted mothers of infants and young …

Application Of Fuzzy Logic For Performance Enhancement Of Drives, Gilberto Costa Sousa

Doctoral Dissertations

Fuzzy logic shows enormous potential for advancing power electronics technology. Its application to DC and AC drives control is discussed here.

Initially, a phase-controlled bridge converter DC drive was considered. Analysis of converter performance at continuous and discontinuous conduction modes was first conducted. Fuzzy control was used to linearize the transfer characteristics of the converter in discontinuous conduction mode. It was then extended to current and speed loops, replacing the conventional proportional-integral controllers. The control algorithms were developed in detail, and verified by PC-SIMNON (developed by Lund Institute of Technology Sweden) digital simulation. Significant performance improvement was achieved over conventional …

A Critique Of Moral Realism, Margaret Ayotte Levvis

Doctoral Dissertations

This work argues that leading forms of contemporary moral realism are inadequate, and that the philosophical attempt to vindicate the naive moral realism implicit within popular ethical opinion is misguided. In their place a form of moral anti-realism is defended which construes the appropriateness or inappropriateness of moral practices and the correctness or incorrectness of moral judgments as relative to linguistic conventions, but it is also argued that such relativism does not undermine the objectivity of moral truth if one is prepared to adopt Blackburn's (1984) quasi-realist conception of ontological comnitment.
