Computational Analysis Of Pitch Stability For A Slotted Airfoil In Ground Effect, Meagan L. Hubbell
Computational Analysis Of Pitch Stability For A Slotted Airfoil In Ground Effect, Meagan L. Hubbell
Graduate Theses, Dissertations, and Problem Reports (ETD)
Ground effect is a phenomenon which occurs when flow is displaced around a moving body in close proximity to the ground. This displacement is caused by compressed air that becomes trapped during motion between the body and the ground. The added upward thrust caused by ground effect can be used to generate and augment lift on a small aircraft. AirRay is a small single person, recreational downhill glider that operates within this ground effect. When launched from the top of a hill, it can glide to the base using ground effect for lift.;One of the amplified effects of operating close …

Neuropsychological Functioning Of College Students With Attention Deficit Hyperactivity Disorder, Melanie Ann Nuszkowski
Graduate Theses, Dissertations, and Problem Reports (ETD)
Individuals with Attention Deficit Hyperactivity Disorder (ADHD) often experience significant impairment in multiple life domains not only during childhood, but also throughout their adult lives. While there is no single litmus test for identifying ADHD, neuropsychological tests have been proposed as one means of enhancing identification of ADHD in adults. Theories of ADHD have suggested that deficits in executive functioning underlie the symptom appearance for ADHD; however, meta-analyses have suggested that non-executive functioning skills provide nearly equal discriminatory results. Given the increasing proportion of students with ADHD who are pursuing postsecondary education, the need for further research addressing the impact …

Kepler's Method: The Conjoining Of Theoretical And Empirical Science., Marc M. Mezzina
Graduate Theses, Dissertations, and Problem Reports (ETD)
Johannes Kepler was a mathematician that changed the way that science was conceived and practiced in the early seventeenth century. Kepler’s method of scientific inquiry consisted of the joining of the theoretical aspects of astronomy with the solid empirical proof provided by observations. Kepler’s method would lead him to the discovery of his three laws of planetary motion, as well as change the fundamental questions asked by the subject of astronomy. This is a look in the method employed by Kepler throughout his most significant scientific works.
