Ranking CubeSat communication systems using a value-centric framework
… their need to support ever-increasing amounts of mission data has become imperative. However, the selection of a communications system is complex endeavor with multiple competing objectives and multiple stakeholders. This already challenging environment is compounded by the fact that CubeSats …

Anomaly detection methods for unmanned underwater vehicle performance data
… problem of detecting anomalies in performance data for unmanned underwater vehicles(UUVs). UUVs collect a tremendous amount of data, which operators are required to analyze between missions to determine if vehicle systems are functioning properly. Operators are typically under heavy time …

Developing a Platform for Expanding AUV exploRation to Longer ranges (PEARL)
… (AUVs) are often limited in their range and mission time due to their battery capacity. Additionally, the data onboard AUVs usually needs to be downloaded directly, due to their limited data transmission capabilities, requiring time and labor to fish the AUVs out of the water. The Platform …

Rapidly Estimating Swarm Resource Needs Through Autonomous Simulation
… implements two resource-aware multi-robot patrol missions in MOOS-IvP. In each mission, vehicles perpetually patrol a grid and must periodically break patrol formation to refuel at a depot. Missions measure their performance based on how frequently robots visit each portion of the mission …

Coast Guard Aviation & the Assignment Problem: An Auction Model to Allocate the Future 'All-Jayhawk' Fleet
… optimized assignments, the CG can achieve better mission value at cost. The objective of this thesis is to build a model to aid the CG in making rotary wing aircraft basing and satellite unit organizational decisions as it transitions to an ‘All Jayhawk’ fleet of 127 aircraft, by building a model …
