Evaluating The Accuracy Of Inertial Measurment Units In Detecting Gait Parameters For Lower Limb Prosthesis And Orthosis Users, Bryce Fuller
Evaluating The Accuracy Of Inertial Measurment Units In Detecting Gait Parameters For Lower Limb Prosthesis And Orthosis Users, Bryce Fuller
USF Tampa Graduate Theses and Dissertations
A Gait Extraction System (GES) was developed to investigate the accuracy of wearable sensors by producing gait parameters, to be compared against a gold standard motion capture system. Two inertial measurement units (IMUs) were placed in the lower limb region, specifically in the shank region of each leg. The GES uses algorithms to extract the gait cycle from raw acceleration data to produce gait parameters such as stride length, stride time, step length, step time, stance time, swing time and cadence. There were three main trials that consisted solely of a flat road, a road with small hills and a …
Multi Segment Finite Element Analysis Of The Lumbar Spine, James J. Doulgeris
Multi Segment Finite Element Analysis Of The Lumbar Spine, James J. Doulgeris
USF Tampa Graduate Theses and Dissertations
Finite element analysis of the spine has become popular over the past several decades. However, the current studies often use minimal specimens for modeling. The purpose of this study was to validate and analyze multiple finite element models with data from in vivo experiments and other finite element studies before future investigations. This study developed eight (8) lumbar spine (L2-L5) finite element models followed by finite element analysis of simulated bending in the six (6) basic motions. CT scans were obtained from four (4) males and four (4) females between the ages of forty-four (44) and seventy-three (73) years old. …
How Some Arboreal Salamanders (Genus Aneides) Jump, Glide, And Generate Lift, Christian E. Brown
How Some Arboreal Salamanders (Genus Aneides) Jump, Glide, And Generate Lift, Christian E. Brown
USF Tampa Graduate Theses and Dissertations
The jumping and subsequent aerial behaviors of arboreal lungless salamanders (genus Aneides) had never been investigated or described. The aims of this research were to (1) compare jumping performance within the family Plethodontidae with a special focus on arboreal species from genus Aneides, (2) describe the biomechanics and kinematics of aerial behaviors after a jump or extended fall, and (3) model airflow over the morphology of the most aerially adept salamanders to investigate if they are capable of generating lift. First, I recorded salamanders jumping, locomoting vertically, dropping, and flying in a vertical wind tunnel. Then, I laser-scanned and reconstructed …
