A Naturalistic Study Of Long-Term Working Memory Capacity For Meaningful Visual And Auditory Stimuli, Joseph M. Jaworski

Doctoral Dissertations and Master's Theses

The purpose of this study was to explore long-term working memory in experts in an information-rich, dynamic domain. Of particular interest were strategies experts use to enhance long-term working memory capacity when working with verbal versus aural information. Three air traffic control instructors participated in four complex air traffic control scenarios, two radar scenarios in which information was presented visually and two non-radar scenarios in which information presentation was purely aural. Participants recalled traffic situation information at two points during and at the end of each scenario. Recall data for each scenario type were assessed in terms of evidence about …

Spatial Cognition Differences Between Men And Women In Spatial Cue Environments During Flight Simulation, Heidi Crystal Kim

Doctoral Dissertations and Master's Theses

Ground reference maneuvers are an important component of pilot training. In order to perform these maneuvers, pilots rely on cues from the environment to determine where their aircraft is in relation to objects on the ground. This process requires a high degree of spatial cognition, which refers to the cognitive processes used to orient oneself in space. Two factors that can influence spatial cognition in the context of aviation ground reference maneuvers are the availability of spatial cues and the biological sex of the pilot. Research suggests spatial cues aid in the identification of potentially dangerous objects. In the context …

Pre-Exposure Training As A Means To Reduce Vection Induced Symptoms Of Motion Sickness, Nicholas James Stapleton

Doctoral Dissertations and Master's Theses

The focus of this study was designed to empirically examine the effect of inducing mild motion sickness as an ameliorative to a more severe motion sickness exposure. Twenty-seven participants were selected for this study based upon their susceptibility to motion sickness, that is, only people who were determined to be motion susceptible were tested. All participants were exposed to a motion sickness-inducing environment. Eighteen participants were trained to adapt to motion sickness by exposure to a milder motion sickness-inducing environment, ending either 6 hours or 24 hours prior to the more severe motion test environment.

Participants during the pre-exposure experimental …

Reducing Uncertainty In Fatigue Life Limits Of Turbine Engine Alloys, J M. Larson, S K. Jha, C J. Szczepanski, M J. Caton, R John, A H. Rosenberger, D J. Buchanan, P J. Golden, J R. Jira

United States Air Force: Publications

In probabilistic design of materials for fracture-critical components in modern military turbine engines, a typical maximum design target risk (DTR) is 5 X 10^-8 component failures/engine flight hour. This metric underscores the essential role of safety in a design process that simultaneously strives to achieve performance, efficiency, reliability, and affordability throughout the life cycle of the engine. Traditionally, the design and life management approaches for engine materials have typically relied on extensive testing programs to produce large databases of fatigue data, from which statistically based life limits are derived by extrapolation from the mean fatigue behavior. However, we …

Stability And Power Optimality In Time-Periodic Flapping Wing Structures, Bret Stanford, Philip Beran, Richard Snyder, Mayuresh Patil

United States Air Force: Publications

This paper investigates the nonlinear dynamics of a vehicle with two flexible flapping wings. The body dynamics and the wings' deformation are monolithically grouped into a single system of equations, with aerodynamics accounted for by a quasi-steady blade element method. A periodic shooting method is then used to locate closed orbits of this non-autonomous system, and Floquet multipliers assess the linearized stability about the nonlinear orbit. This framework is then exposed to a gradient based optimizer, in order to quantify the role of wing planform variables, wing structure variables, and kinematic actuation variables in obtaining vehicles with superior open-loop stability …

Direct Flutter And Limit Cycle Computations Of Highly Flexible Wings For Efficient Analysis And Optimization, Bret Stanford, Philip Beran

United States Air Force: Publications

The usefulness of flutter as a design metric is diluted for wings with destabilizing (softening) nonlinearities, as a stable high-amplitude limit cycle (subcritical) may exist for flight speeds well below the flutter point. It is thus desired to design aeroelastic structures such that the post-flutter behavior is as benign (i.e., supercritical) as possible, among the other constraints commonly considered in the optimization process. In order to account for these metrics in an accurate and efficient manner, direct tools are utilized to first locate the Hopf-point (flutter speed), and then to obtain a nonlinear perturbation solution via the method of multiple …

Direct Ignition And S-Curve Transition By In Situ Nano-Second Pulsed Discharge In Methane/Oxygen/Helium Counterflow Flame, Wenting Sun, Sang Hee Won, Timothy Ombrello, Campbell Carter, Yiguang Ju

United States Air Force: Publications

A well-defined plasma assisted combustion system with novel in situ discharge in a counterflow diffusion flame was developed to study the direct coupling kinetic effect of non-equilibrium plasma on flame ignition and extinction. A uniform discharge was generated between the burner nozzles by placing porous metal electrodes at the nozzle exits. The ignition and extinction characteristics of CH4/O2/He diffusion flames were investigated by measuring excited OH* and OH PLIF, at constant strain rates and O2 mole fraction on the oxidizer side while changing the fuel mole fraction. It was found that ignition and extinction occurred with an abrupt change of …

The Challenge Of Intervention To Monetarily Support Or Not Support The National Airline Carriers: A Case Of The Airline Industry In Eastern Europe, Dawna L. Rhoades, Tamilla Curtis

Management, Marketing and Operations - Daytona Beach

The airline industry has been considered a special case in national and international business virtually since its beginning. Because of this status, national governments have repeatedly intervened to support national carriers in order to prevent bankruptcy and failure. The nations of Eastern Europe are no exception to this rule and are currently considering additional intervention to support their carriers. This paper explores the rationale for intervention, particularly the suggested economic impact, using traffic and financial information from the Flightglobal database. The conclusion is that the case for intervention is weak at best and that the results may not justify the …

In order to facilitate a significant overhaul of the civilian National Airspace System (NAS), the Federal Aviation Administration (FAA) has partnered with many federal agencies, such as the departments of Transportation (DOT), Defense (DoD), Homeland Security (DHS), and Commerce (DOC) and the National Aeronautics & Space Administration (NASA) through a consolidated Joint Planning and Development Office (JPDO) that was established by Congress in 2003 in the VISION 100 – Century of Aviation Reauthorization Act (JPDO, 2012). The JPDO has proposed replacing the old NAS structure of primarily ground-based navigation with robust satellite-enabled air traffic procedures and to supplement ground-based air …

Indeterminate Masses, Elements And Models In Information Fusion, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

In this paper at the beginning, we make a short history of the logics, from the classical Boolean logic to the most general logic of today neutrosophic logic. We define the general logic space and give the definition of the neutrosophic logic. Then we introduce the indeterminate models in information fusion, which are due either to the existence of some indeterminate elements in the fusion space or to some indeterminate masses.

The best approach for dealing with such models is the neutrosophic logic, which is part of neutrosophy. Neutrosophic logic is connected with neutrosophic set and neutrosophic probability and statistics.
