Density-dependent Stiffness in Petiole Biomechanics
(Georgia Institute of Technology, 2008-05-05)
Morphological features of plants vary with increasing size. This relationship between different physical characteristics and size is referred to as allometry. Recently allometric research focused on plants and in particular ...
Granular Behavior of the Honey Bee Pollen Pellet and Associated Removal Mechanics
(Georgia Institute of Technology, 2019-05)
Honey bees collect and store pollen in the form of a pellet by packing the pollen grains together with regurgitated nectar. This research has indicated that the pollen pellet is a granulated suspension, i.e. a fluid that ...
Multi-Variant Differentiation of Healthy and Cancerous White Blood Cells to Progress the Diagnosis of Leukemia
(Georgia Institute of Technology, 2016-05)
Every three minutes, someone in the United States is diagnosed with blood cancer, the most common of which being Leukemia, or the cancer of white blood cells [1]. Distinguishing between healthy white blood cells and leukemia ...
Validation Testing of Multiple IMUs as Sensors of Joint Angles
(Georgia Institute of Technology, 2021-12)
Hip flexion angles were measured on a subject for both walking and sprinting trials using two different IMUs: Microstrain’s IMU and Adafruit’s BNO055 IMU. These measurements were compared against measurements simultaneously ...
Centralization of Muscular Control in Blaberus discoidalis as a Variable of Terrain Roughness
(Georgia Institute of Technology, 2019-05)
The purpose of this study was to illustrate how the neuromuscular architecture of Blaberus discoidalis cockroaches changes in response to variations in their environment. The species Blaberus discoidalis shares the single ...
The Biomechanics of Elephant Trunk Elongation
(Georgia Institute of Technology, 2022-05)
The elephant trunk is one of the largest, most versatile boneless appendages, dwarfing similar muscular hydrostats such as octopus tentacles and chameleon tongues. Little is known about how an elephant’s large size influences ...
Characterization of Rat Optic Nerve Head (ONH) Biomechanics through Finite Element (FE) and Sensitivity Analysis of Tissues
(Georgia Institute of Technology, 2017-12)
ONH pathophysiology in glaucoma is poorly understood. However, the rat model of glaucoma is especially useful for learning how complex optic ONH biomechanics affect glaucomatous cell death. Because of human and rat ONH ...
Leg, vertical, and joint stiffness levels in rear-foot and fore-foot strike landings
(Georgia Institute of Technology, 2014-05-02)
Bouncing gait, specifically hopping, running, and jumping, involves a complex combination of legs, joints, muscles, and nerves coordinated to perform simple biomechanical tasks. The findings associated with spring-mass ...
Predicting Metabolic Cost Using Cumulative Muscle Activation Per unit Distance
(Georgia Institute of Technology, 2023-01-18)
Many studies are currently being conducted in order to optimize the functions of exoskeletons in a way that generates the greatest benefit for the user. However, this research is hampered by the traditional methodology of ...
Effects of Muscle-Based Control and Electrical Stimulation of Residual Sensory Nerve on Biomechanics of Locomotion with Transtibial Prosthesis
(Georgia Institute of Technology, 2022-05)
This study examines the use of muscle activity and nerve stimulation for trans-tibial prosthetic control. We tested various modes of an osseointegrated prosthesis – in a cat subject – that varied in their implementation ...
