Simulating Dynamic Vehicle Maneuvers Using Finite Elements For Use In Design Of Integrated Composite Structure
… doubled as mostly satisfactory structures for vehicle loads. The use of composite structures and the directionality of their material properties has created a need for more detailed loading scenarios to evaluate their ability to transfer load. This thesis presents a framework for evaluating the …

Disturbance, Functional Diversity and Ecosystem Processes: Does Species Identity Matter?
… disturbances associated with military training, vehicle maneuvers, and fire; affect functional group abundance, within functional group richness, and total species richness. I found strong effects of vehicle maneuvers on soil physical properties including an increase in bulk density and reduction …

Sampling-based motion planning algorithms for dynamical systems
… systems, including time-optimal off-road vehicle maneuvers as the main example. Second, we propose a semi-analytic TPBVP approach for differentially flat systems or partially flat systems, by which the computation of vehicle maneuvers is expedited and the capability to handle extreme …

A Greedy Search Algorithm for Maneuver-Based Motion Planning of Agile Vehicles
… for maneuver-based motion planning of agile vehicles. In maneuver-based motion planning, vehicle maneuvers are solved offline and saved in a library to be used during motion planning. From this library, a tree of possible vehicle states can be generated through the search space. A …

Radar and LiDAR Fusion for Scaled Vehicle Sensing
… was developed to track a maneuvering full-scale vehicle using an extended Kalman filter (EKF) and the joint probabilistic data association (JPDA). Second, a 1/5th scaled vehicle performed the same vehicle maneuvers but scaled to approximately 1/5th the distance and speed. When taking the scaling …

Characterization of Surface Karst Using LiDAR and Field Traverses, Fort Hood Military Installation, Coryell County, Texas
… for training exercises that include heavy vehicle maneuvers and simulated combat. Traditional karst surveys are often time-consuming and require extensive field analyses to adequately characterize large areas. Bias is given to areas that are most easily accessible and false negatives are …

A Genetic Algorithm Framework using Variable Length Chromosomes for Vehicle Maneuver Planning
… reconfigurable systems are fleets of maneuvering vehicles. Considering this class naturally leads to the question of how to generate the optimal set of maneuvers over an operational campaign. This thesis presents a genetic algorithm framework with Variable Length Chromosomes (VLC) to find this …

Autonomous orbital rendezvous using angles-only navigation
… relative motion orbital trajectories. Chaser vehicle maneuvers designed to enhance the estimator's observability of the downrange distance to the target are considered. The target vehicle is assumed to be non-maneuvering and in a near-circular orbit. The modeled system includes representative …

A Naturalistic Driving Study for Lane Change Detection and Personalization
… features are becoming nearly ubiquitous in new vehicles. The intent of the Driver Assistant features is to assist the driver in making safer decisions. The intent of Autonomous Driving features is to execute vehicle maneuvers, without human intervention, in a safe manner. The overall goal of …

Optimal tank design and directional dynamic analysis of liquid cargo vehicles under steering and braking
… characteristics of partially-filled tank vehicles are adversely influenced by the movement of the liquid cargo within the tank. The directional dynamics and stability characteristics of partially-filled tank vehicles are analyzed and enhanced through formulation of an optimal tank …

Enhancement of perception with the application of stochastic vestibular stimulation
… during planetary landing, docking, or other vehicle maneuvers. In a first experiment, upright roll tilt direction recognition thresholds, which elicit responses from both the semicircular canals and otoliths, were measured with varying levels of SVS applied. Upright roll tilt direction …

Design and Throughput Capacity Evaluation of Pickup and Dropoff (PUDO) Facilities
… this trend with the introduction of self-driving vehicles, imply that PUDO facilities will become more widespread and substantial. The current practice of mostly using curbsides for PUDO operations will not be sustainable as demand increases. This dissertation presents stochastic modeling and …
