Development And Validation Of A Machine-Learned Actuator Line Model For Rotors, Joshua L. Bowman Dec 2025

Development And Validation Of A Machine-Learned Actuator Line Model For Rotors, Joshua L. Bowman

Theses and Dissertations

This dissertation develops and validates a machine‑learned (ML) actuator line model (ALM) as an advancement in rotor modeling that can be applied to diverse engineering applications. The model addresses two standard ALM limitations: dependence on pre‑tabulated lift and drag coefficients and the inability to represent unsteady inflow. The ML‑ALM is trained on a hydrokinetic blade‑resolved simulation database of blade‑element forces under unsteady conditions, and is queried at run time to supply axial, tangential, and spanwise forcing at each actuator element. Validation covers solitary rotor performance and wake predictions against experimental data, and verification in an inline configuration against blade‑resolved simulations …

Netflix And Kill: The Role Of True Crime Consumption In The Development Of Acquired Capability For Suicide, Chandler Jayne Mcdaniel Dec 2025

Netflix And Kill: The Role Of True Crime Consumption In The Development Of Acquired Capability For Suicide, Chandler Jayne Mcdaniel

Theses and Dissertations

The Interpersonal-Psychological Theory of Suicide (IPTS) identifies acquired capability as a key factor contributing to suicidal behavior. Previous research has shown that violent media exposure can increase suicidal risk through desensitization, imitation, and trauma activation. However, little is known about the role of true crime consumption (TCC), a popular form of violent media engagement, in relation to IPTS constructs. This study examined whether TCC predicts acquired capability for suicide, perceived burdensomeness, and thwarted belongingness. A total of 215 participants were retained after data cleaning. Hypotheses predicted that higher TCC would be associated with higher acquired capability (H1), that TCC would …
