An Unmanned Aerial System For Prescribed Fires, Evan M. Beachly
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
Prescribed fires can lessen wildfire severity and control invasive species, but some terrains may be difficult, dangerous, or costly to burn with existing tools. This thesis presents the design of an unmanned aerial system that can ignite prescribed fires from the air, with less cost and risk than with aerial ignition from a manned aircraft. The prototype was evaluated in-lab and successfully used to ignite interior areas of two prescribed fires. Additionally, we introduce an approach that integrates a lightweight fire simulation to autonomously plan safe flight trajectories and suggest effective fire lines. Both components are unique in that they …

Rate Based Impact Analysis, Nishant Sharma
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
Impact Analysis (IA) identifies control and data dependencies to determine the system components that could be affected by a change. Changes to robotic systems as they are updated often alter the flow of control and sensor data. Changes to the rates at which data is published from sensors, controllers, and other parts of the system are particularly subtle and difficult to detect. These rate changes, even if minor (e.g. lowering the frame rate of a camera), can propagate throughout the system and have broad impacts. However, for robotic systems, these changes in flow rate cannot be precisely tracked by just …
