Fatigue Behavior and Modeling of Polyether Ether Ketone under Variable Amplitude and Multiaxial Loading
(2020-07-22)
Experimental and analytical roadmap to thoroughly understand and establish benchmark material properties for unfilled polyether ether ketone (PEEK) under monotonic tension and compression, as well as uniaxial and multiaxial ...
Path Following and Obstacle Avoidance for Autonomous Ground Vehicles Using Nonlinear Model Predictive Control
(2020-05-18)
This thesis presents a nonlinear model predictive controller (NMPC) for path following and obstacle avoidance in automated driving systems.
Automated safety control systems have been increasingly effective at reducing ...
Initialization of a Pedestrian Navigation System Using a Transfer Alignment Approach
(2020-08-11)
Pedestrian navigation techniques are used to provide positioning information in lieu of or to supplement more traditional systems such as GNSS. A challenge facing users of pedestrian navigation algorithms is the acquisition ...
Online State and Parameter Estimation for Lithium-ion Batteries Based on a Reduced-order Electrochemical Life Model
(2020-04-22)
Inaccurate estimation of the state-of-charge (SOC) and the state-of-health (SOH) may lead to safety issues. Currently, estimations of SOC and SOH that based on electric equivalent circuit models (ECMs) have been widely ...
