Reinforcement Sailing
This thesis examines applying reinforcement learning to sailing. We give two conceptually different models of a simple sailing boat. Standard tabular reinforcement learning is shown to be ineffective in controlling these naturally continuous models. We examine a method [Smith, 2001b] which adaptively quantises both the state and action spaces and show that it has similar performance to the tabu...
متن کاملApplicatication of the Rhumb Line Control Strategy to the Highly Spinning Dash Orbiter
The paper reveals the essential feature of the attitude control system for the demonstrator of atmospheric reentry system with hyperbolic velocity (DASH) and evaluates its fundamental performance. The spinning DASH orbiter is scheduled to be launched in January 2000 into a geo-stationary transfer orbit (GTO) by the first H-IIA rocket. It deorbits by burning of a solid propellant motor and relea...
متن کاملCompton Sailing and Strong Polarization
It is noted that a surface layer of matter in contact with a sufficiently superEddington, radially combed photon flux typically attains a relativistic coasting state whereby the radiation does not accelerate the matter. Radiation that scatters off this layer is most likely to be observed along the velocity vector of the matter, where it would be strongly polarized. Subject headings: black hole ...
متن کاملSailing through uncertainty.
choice but to pursue science. My dad wouldn’t accept anything but a science degree. He told me in no uncertain terms that if I really wanted to be an English major or a writer, as I said I did, I would need to figure out how to pay for college on my own. I chose a school 2000 miles from home and overloaded my schedule with literature classes that I claimed were required, but I wasn’t brave or i...
متن کاملMathematical Theory of Sailing
We show by computational solution of the incompressible Navier-Stokes equations with friction force boundary conditions, that the classical inviscid circulation theory by Kutta-Zhukovsky for lift and laminar viscous boundary layer theory by Prandtl for drag, which have dominated 20th century fluid dynamics, do not correctly describe the real turbulent airflow around a sail under tacking. We sho...
