Papers Recently Published and Submitted

Science of Autonomy: Time-Optimal Path Planning and Adaptive Sampling for Swarms of Ocean Vehicles

“Science of Autonomy” results obtained by our MSEAS group and recent collaborators are summarized. We present a subset of our results on time-optimal path planning for swarms of ocean vehicles and review some of our research in adaptive sampling. The path planning and adaptive sampling schemes and approaches presented were illustrated by their applications in [...]

Time-Optimal Path Planning in Dynamic Flows using Level Set Equations: Theory and Schemes

We develop a computationally efficient, partial differential equation based methodology that predicts the time-optimal paths of autonomous vehicles navigating in continuous, strong and dynamic flow-fields, obviating the need for heuristics. The goal is to predict a sequence of steering directions so that vehicles can best utilize or avoid flow currents to minimize their travel time. [...]

Global Analysis of Navier-Stokes and Boussinesq Stochastic Flows using Dynamical Orthogonality

We provide a new framework for the study of fluid flows presenting complex uncertain behavior. Our approach is based on the stochastic reduction and analysis of the governing equations using the dynamically orthogonal field equations. By numerically solving these equations we evolve in a fully coupled way the mean flow and the statistical and spatial [...]
