Characterization Of The 2-Phase Turning Response Of Madagascar Hissing Cockroach Biobots To Antennal Stimulation, Stefanie Jane Panzenhagen
Characterization Of The 2-Phase Turning Response Of Madagascar Hissing Cockroach Biobots To Antennal Stimulation, Stefanie Jane Panzenhagen
Graduate Theses - Biology & Biomedical Engineering
Biobots are living insects that are controlled via neurostimulation applied through implanted electrodes and have a variety of potential applications such as search and rescue operations. Madagascar Hissing Cockroaches (MHCs) are commonly used as biobots; however, their use remains under investigation due to lack of a comprehensive motion profile in response to neurostimulation, which makes consistent control a challenge. MHC biobots often exhibit a 2-phase turning response to antennal stimulation, with an initial turn (primary) in the desired direction followed by a “corrective” turn (secondary) in the undesired direction. The purpose of this research is to characterize the 2-phase turning …
Verification And Validation Of Forces From Hippotherapy Rein Simulator, Sonia Sanchez
Verification And Validation Of Forces From Hippotherapy Rein Simulator, Sonia Sanchez
Graduate Theses - Biology & Biomedical Engineering
The thesis describes the redevelopment, testing, and validation of a rein training device intended to help riders learn to guide a horse during hippotherapy sessions. The thesis aims to validate and verify that the forces read by the redeveloped rein simulator were operant within ± 150 grams of the actual weight applied, as well as to investigate the effect of temperature on the system. The simulator focuses on the use of the English style of riding that uses direct force from the reins to guide a horse to turn or stop. Data was collected by hanging weights from the load …
Equilibrium Testing Of Rat Tail Tendon: An Analysis Of The Viscoelastic Properties Of Collagen Under Different Strain Points, Joshua C. Witt
Equilibrium Testing Of Rat Tail Tendon: An Analysis Of The Viscoelastic Properties Of Collagen Under Different Strain Points, Joshua C. Witt
Graduate Theses - Biology & Biomedical Engineering
Instantaneous tensile testing and stress-relaxation testing are forms of mechanical testing used to determine the elastic and viscoelastic properties of biological tissue. Equilibrium testing is a form of testing that combines both of these testing approaches at different strain points to determine the elastic properties of a material and also assess their viscoelastic properties in the same test. This testing method is commonly used on highly viscoelastic materials such as cartilage but has never been fully described in dense collagenous materials such as tendon or ligament. This analysis utilizes different strain points selected to capture the classic non-linear behavior of …
A Comparative Evaluation Of Cadaveric And Composite Femur Models For Total Hip Arthroplasty, Anderson Lynn Adams
A Comparative Evaluation Of Cadaveric And Composite Femur Models For Total Hip Arthroplasty, Anderson Lynn Adams
Graduate Theses - Biology & Biomedical Engineering
Composite bones are often used in testing of orthopedic implants due to their relative ease of use and low inter-specimen variability when compared to cadaveric bones. Tests were run to ensure that the composite bones remained an acceptable model for cadaver bones throughout surgical manipulation. Composite (n=6) and cadaver (n=6) femur specimen were subjected to a total hip arthroplasty (THA). Flexural rigidity, axial stiffness, and axial strain measurements were taken at various stages in the surgical process. The composite and cadaver specimen were not found to behave similarly in either flexural rigidity or axial stiffness tests. The results showed a …
Development And Validation Of A Robust, Adjustable Hippotherapy Simulator, Melissa Montgomery
Development And Validation Of A Robust, Adjustable Hippotherapy Simulator, Melissa Montgomery
Graduate Theses - Biology & Biomedical Engineering
This thesis describes all aspects of development, testing, refinement, and validation of a robust, adjustable hippotherapy simulator. This simulator primarily focuses on physical therapy; however, emotional benefits can be realized. It uniquely innovates on an effective design that has only partially been addressed in other simulators. Using a variable drive for adjustable speed, it incorporates reinforcements to increase load capacity along with removable camshafts that adjust the throw heights in the device’s simulated hips and shoulders. For testing and validation, Qualisys software and motion capture supported analysis of the device’s motion paths and speeds. Riders weighing approximately 135-300 pounds successfully …
