Characterization of side-slip dynamics in Land Rover LR3 for improved high speed autonomous control
In this thesis, the side slip control dynamics of the Land Rover LR3 platform are examined for autonomous control. As autonomy becomes implemented in high speed safety applications, the importance of an accurate model for the vehicle becomes crucial for obstacle avoidance and emergency maneuvers. …

Mesoscale Forces and Grain Motion in Granular Media Exhibiting Stick-Slip Dynamics: Effects of Friction and Grain Shape
… of friction and grain shape on grain-scale dynamics, properties of mesoscale force chains, and macroscopic stick-slip dynamics of granular materials through novel experiments. In one set of experiments, an intruder is pushed by a spring through an annular cell filled with a quasi-2D …

Traction Control Study for a Scaled Automated Robotic Car
… 1/10th scale robotic car to operate at a desired slip. Controlling the robot car at any desired slip has a direct relation to the amount of force that is applied to the driving wheels based on road surface conditions. For this model, the desired traction/slip is maintained for a specific surface …

Novel Multitemporal Synthetic Aperture Radar Interferometry Algorithms and Models Applied on Managed Aquifer Recharge and Fault Creep
… phenomena, detecting five significant slow slip events (SSEs) along the Southern San Andreas Fault using multitemporal SAR interferometric time series from 2015-2021. These SSEs govern aseismic slip dynamics, manifesting as avalanche-like creep rate variations. The study further investigates …

Particle Filtering and Optimal Control for Vehicles and Robots
… A novel approach to model-based joint wheel-slip and motion estimation of four-wheeled vehicles is developed. Unlike other approaches, the method explicitly models the nonlinear slip dynamics in the state and measurement equations. Excellent and consistent accuracy for all relevant states are …

FLOW FORMING OF CAPILLARY INTERFACES: DROP IMPACT AND THE MOBILE CONTACT LINE
… we use high-speed imaging to resolve the stick-slip dynamics of the CL. The only form of dissipation during this fast-time scale is CL dissipation. Loss of energy occurs during a slip leg, and this observation is used to derive a closed-form expression for the ‘post-pinning’ energy. This …

Non-universal behavior of intermittent flow in microplasticity
… can indeed accurately trace very rapid dynamic slip in microcrystals due to its low mobile mass and capacity for high data acquisition rates. Next, we examine the avalanche size statistics across a wide range of microstructural and experimental variables, and find that while the observed size …
