Precise Landing Of Vtol Uavs Using A Tether, Jeremy W. Rathjen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Unmanned Aerial Vehicles (UAVs), also known as drones, are often considered the solution to complex robotics problems. The significant freedom to explore an environment is a major reason why UAVs are a popular choice for automated solutions. UAVs, however, have a very limited flight time due to the low capacity and weight ratio of current batteries. One way to extend the vehicles' flight time is to use a tether to provide power from external batteries, generators on the ground, or another vehicle. Attaching a tether to a vehicle may constrain its navigation but it may also create some opportunities for …

Jurors' Perceptions Of Child Sexual Abuse Disclosure Patterns, Hannah Elias

Graduate Theses, Dissertations, and Problem Reports (ETD)

The process of child disclosure of sexual abuse can be complex. Children often disclose abuse consistently across settings (continuous disclosure), though there is research to support that children may deny abuse or recant their allegations despite the abuse having truly occurred (London et al., 2008; Bradley & Wood, 1996; Malloy, Lyon, & Quas, 2007). In this study, data was collected from voluntary MTurk users (N = 688). Mock jurors responded to a survey assessing perceptions of child credibility, defendant guilt, and child susceptibility to external influence in response to each CSA disclosure pattern (continuous disclosure, denial, recantation). Additionally, expert …

Combustion Feature Characterization Using Computer Vision Diagnostics Within Rotating Detonation Combustors, Kristyn B. Johnson May

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, the possibilities of higher thermodynamic efficiency and power output have led to increasing interest in the field of pressure gain combustion (PGC). Currently, a majority of PGC research is concerned with rotating detonation engines (RDEs), devices which may theoretically achieve pressure gain across the combustor. Within the RDE, detonation waves propagate continuously around a cylindrical annulus, consuming fresh fuel mixtures supplied from the base of the RDE annulus. Through constant-volume heat addition, pressure gain combustion devices theoretically achieve lower entropy generation compared to Brayton cycle combustors. RDEs are being studied for future implementation in gas turbines, where …

Analyzing The Viability Of Direct Pcr For Use In Conjunction With Cyanoacrylate Enhanced Fingerprints, Coral M. Smith

Learning Representations For Human Identification, Sinan Sabri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Long-duration visual tracking of people requires the ability to link track snippets (a.k.a. tracklets) based on the identity of people. In lack of the availability of motion priors or hard biometrics (e.g., face, fingerprint, or iris), the common practice is to leverage soft biometrics for matching tracklets corresponding to the same person in different sightings. A common choice is to use the whole-body visual appearance of the person, as determined by the clothing, which is assumed to not change during tracking. The problem is challenging because distinct images of the same person may look very different, since no restrictions are …

Enemies, Allies, And Opportunities: The Politics Of Noblewomen’S Lawsuits In Early Modern Piedmont, Catherine Ferrari

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation considers early modern law courts as political venues in which noble families not only asserted claims to wealth, property, and inheritance but also sought to enhance their reputation and influence. By studying the archives of elite families in Piedmont from the mid-sixteenth to the mid-seventeenth centuries, I argue that noblewomen used the law to gain a political voice, defending their legal claims against other family members in highly visible conflicts in which not only their property but their standing at the court of the duke of Savoy was at stake. These women exploited legal procedures and drew on …
