Development And Validation Of Wireless Sensors For Applications To Human Head Angular And Mechanical Motions, Karthick Natesan
Development And Validation Of Wireless Sensors For Applications To Human Head Angular And Mechanical Motions, Karthick Natesan
USF Tampa Graduate Theses and Dissertations
In this project, we programmed a 9 degree of freedom Razor sensor, which incorporates an accelerometer and gyroscope to measure the head linear and angular motions produced by activities of daily living (ADL). The majority of studies concentrate on linear accelerations, so the purpose of this study is to determine the importance of both linear and angular components of acceleration in everyday activities and find interlinked relation between them. The sensor was validated using another calibrated and validated system. The general size and wireless nature make this sensor very suitable for use with human subjects. After obtaining informed consent, we …
Clinging In Plethodontid Salamanders, Mary Kathleen O'Donnell
Clinging In Plethodontid Salamanders, Mary Kathleen O'Donnell
USF Tampa Graduate Theses and Dissertations
The ability to cling to and climb on inclined, vertical, and inverted surfaces gives animals access to additional shelter and food and may provide refuge from unsuitable temperature and moisture conditions or escape from ground-dwelling predators. Salamanders have been shown to cling to surfaces and engage in climbing behavior, but their maximum clinging capability and mechanisms of attachment are not well understood. While some arboreal salamanders possess prehensile tails, salamanders lack many morphological adaptations for attachment, such as claws, toe pads, and fibrillar adhesive pads. Maximum cling performance and surface area of attachment were measured, and the adhesive capability of …
Psychological Responses To High-Intensity Interval Training Exercise: A Comparison Of Ungraded Running And Graded Walking, Abby Fleming
Psychological Responses To High-Intensity Interval Training Exercise: A Comparison Of Ungraded Running And Graded Walking, Abby Fleming
USF Tampa Graduate Theses and Dissertations
This study investigated the effects of ungraded running and graded walking as modalities of HIIT on enjoyment, perceived exertion, and affect. 29 healthy males and females (aged 23.3 ± 5.1) volunteered to participate in the study. Participants completed six visits to the laboratory: the first was a medical screening to ensure safety of the participants. For the second and third visits, participants completed two maximal treadmill exercise tests, one running and one walking. On the fourth visit, the speed needed for the run HIIT (running speed: 6.9 ± 1.2mph) and the grade needed for the walk HIIT (walking speed: 3.3 …
