Evaluating Dynamic ‘Landing Gear Unsafe’ Auditory Alerts As A Defense Against Habituation, Vincenzo Fasano
Evaluating Dynamic ‘Landing Gear Unsafe’ Auditory Alerts As A Defense Against Habituation, Vincenzo Fasano
Doctoral Dissertations and Master's Theses
Auditory alerts are widely used in today's daily routine. Unlike their visual counterparts, auditory alerts can be used to capture someone's attention, even though the user is not within visual range. As beneficial as auditory alerts can be, it is possible to become habituated to alerts. Habituation is the elimination of a response as a result of continuous exposure to a stimulus. In this small-scale study, methods to reduce pilot habituation to the 'landing gear unsafe' auditory alert were investigated. Ten subjects executed eight non-precision instrument approaches that exposed the subjects to the 'landing gear unsafe' auditory alert for a …
Level Of Agreement In The Mental Models Of Human Factors Practitioners And Systems Engineers Working In Collaborative Teams, Jerry A. Gordon
Level Of Agreement In The Mental Models Of Human Factors Practitioners And Systems Engineers Working In Collaborative Teams, Jerry A. Gordon
Doctoral Dissertations and Master's Theses
Emerging research in complexity science recognizes traditional techniques for engineering systems do not always work for complex systems. Designing complex systems requires individuals to have knowledge of engineering as well as human performance. To this end, design efforts rely often on multi-disciplinary teams. While any two members of a design team may view the system design problem in vastly different manners, this study sought to identify a possible systemic effect on approach by the differing education and experience obtained by social practitioners, represented by human factors, and technical practitioners, represented by systems engineers. It further examined the impact of the …
Determining Kanban Size Using Mathematical Programming And Discrete Event Simulation For A Manufacturing System With Large Production Variability, Abigail Michele Gaston
Determining Kanban Size Using Mathematical Programming And Discrete Event Simulation For A Manufacturing System With Large Production Variability, Abigail Michele Gaston
Doctoral Dissertations and Master's Theses
In order to become more competitive and aggressive in the market place it is imperative for manufacturers to reduce cycle time, limit work-in-process, and improve productivity, responsiveness, capacities, and quality. One manner in which supply chains can be improved is via the use of kanbans in a pull production system. Kanbans refer to a card or signal for productions scheduling within just-in-time (JIT) production systems to signal where and what to produce, when to produce it, and how much. A Kanban based JIT production system has been shown to be beneficial to supply chains for they reduce work-in-process, provide real …
Effects Of Visual Interaction Methods On Simulated Unmanned Aircraft Operator Situational Awareness, Brent A. Terwilliger
Effects Of Visual Interaction Methods On Simulated Unmanned Aircraft Operator Situational Awareness, Brent A. Terwilliger
Publications
The limited field of view of static egocentric visual displays employed in unmanned aircraft controls introduces the soda straw effect on operators, which significantly affects their ability to capture and maintain situational awareness by not depicting peripheral visual data. The problem with insufficient operator situational awareness is the resulting increased potential for error and oversight during operation of unmanned aircraft, leading to accidents and mishaps costing United States taxpayers between $4 million to $54 million per year. The purpose of this quantitative experimental completely randomized design study was to examine and compare use of dynamic eyepoint to static visual interaction …
