Changes In Structural Health Monitoring System Capability Due To Aircraft Environmental Factors, Jeffrey D. Kuhn

Theses and Dissertations

Structural Health Monitoring (SHM) promises to decrease the maintenance cost and increase the availability of aging aircraft fleets by fundamentally changing the way structural inspections are performed. But this promise can only be realized through the consistent and predictable performance of a SHM system throughout the entire remaining life of an aircraft. In a sensor-based SHM system, sensor signal changes are analyzed and interpreted to identify structural flaws. But aircraft environmental factors such as temperature fluctuations, cyclic strain and exposure to various aircraft fluids also have the potential to change SHM sensor signals, raising questions about long term SHM system …

The Interaction Of Motivational Orientation And Social Context In A Flight Setting, Noelle D. Brunelle

Master's Theses - Daytona Beach

The purpose of this study was to explore the effects of motivational orientation and social context on decisions made during flight. Cultural dimensions such as power distance, uncertainty avoidance and individualism have been found to correlate with aviation accident rates. Self-determination theory provides a schedule of social contexts and cues that support, control or thwart individual motivation, with the task-focused properties of intrinsic motivation and the external (group) focus of extrinsic motivation similar to descriptions of the cultural dimensions of individualism and collectivism. In addition, studies have demonstrated contextual cues may be used to prime cognitive goals, behaviors and strategies. …
