Investigation Of Optimization Targets For Predictive Simulation Of Human Gait With Model Predictive Control, Jessica Brianne Thayer
Master's Theses (2009 -)
The design and development of gait-related treatments and devices is inhibited by anabsence of predictive gait models. Understanding of human gait and what motivates walkingpatterns is still limited, despite walking being one of the most routine human activities. While asignificant body of literature exists on gait modeling and optimization criteria to achievesimulated, normal gait, particularly with neuromuscular models, few studies have aimed to applyoptimization targets which approximate metabolic cost to mechanical gait models. Even fewerhave attempted this predictively, with no joint angle data specified a priori. The Sunmodel [31], [32] is one such …
Multiscale Analysis Of Soil-Strap Interactions In Mechanically Stabilized Earth Retaining Walls, Max Willingham
Multiscale Analysis Of Soil-Strap Interactions In Mechanically Stabilized Earth Retaining Walls, Max Willingham
Master's Theses (2009 -)
A numerical pullout test was built using the discrete element method (DEM) to model and capture the pullout response of steel reinforcements and soil in mechanically stabilized earth (MSE) walls. Through numerical modeling, microscale phenomena showing aggregate behavior in response to the reinforcement can be used to gain insight into the macroscale structure. The general setup of the simulation is a steel specimen encased in a rectangular apparatus filled with particles. A normal pressure is applied to the top layer of particles while the strap is slowly removed from the box until it reaches a prescribed displacement.The simulation was …
