Acoustic Source Localization With A Vtol Suav Deployable Module, Kory Olney

USF Tampa Graduate Theses and Dissertations

A real time acoustic direction-finding module has been developed to estimate the ele- vation and azimuth of an impulsive event while function aboard a small unmanned air- craft vehicle. The generalized cross-correlation with phase transform method was used to estimate time differences of arrival in an 8 channel microphone array. A linear least squares approach was used to calculate an estimate for the direction of arrival. In order to accomplish this task, a vertical takeoff and landing small unmanned aircraft system was assembled to host the direction finding module. The module itself is made up of an eight-channel synchronous analog-to-digital …

Effects Of Alternative Seating On Children With Disabilities, Jessica Hoofman

USF Tampa Graduate Theses and Dissertations

Children with disabilities in school settings often display problem behavior. These challenging behaviors can be inattention, disruptions in class, difficulties with transitions between tasks, and low task motivation. These types of behaviors can lead to problems for the students with their peers, teachers, and school staff. One way to decrease problem behavior is to implement antecedent manipulations to prevent problem behavior from ever occurring. One type of antecedent manipulation is using alternative seating in the classroom, such as stability balls or stabili-t stools. However, little research has been conducted to evaluate different types of alternative seating, therefore this study used …

Neutrophil Extracellular Traps And Vascular Barrier Injury, Jamie E. Meegan

USF Tampa Graduate Theses and Dissertations

Sepsis is a life-threatening inflammatory condition with high morbidity and mortality rates. Though improvements to diagnosis and management of sepsis have been made, the complexity of the disease process and an incomplete understanding of its endpoint mechanisms have prevented major breakthroughs for early diagnosis and treatment. Representing a common endpoint in a number of inflammatory injuries including sepsis, endothelial barrier dysfunction causes fluid leakage and leukocyte infiltration that leads to tissue damage and multiple organ failure. Therefore, elucidating mechanisms of endothelial barrier regulation is needed to further develop targeted therapies in inflammatory disease.

Sepsis is characterized by a hyperinflammatory response …

Factors Explaining Changes In Household Vehicle Miles Of Travel, Richard Driscoll
