The infalling photon, the infalling particle, and the observer at rest near the horizon of a black hole
(IOP Publishing, 2020-11)
When a massive test particle or a photon fall radially into a black hole, their energy, as measured by a static observer located very close to the horizon, diverges. In introductory courses on general relativity, this fact ...
A Receding Horizon Framework for Autonomy in Unmanned Vehicles
(Cornell University, 2019-06)
In this article we present a unified framework based on receding horizon techniques that can be used to design the three tasks (guidance, navigation and path-planning) which are involved in the autonomy of unmanned vehicles. ...
Robust stability of moving horizon estimation for non-linear systems with bounded disturbances using adaptive arrival cost
(Institution of Engineering and Technology, 2020-12)
The robust stability and convergence to the true state of a moving horizon estimator based on an adaptive arrival cost are established for non-linear detectable systems in this study. Robust global asymptotic stability is ...
Virasoro Hair and Entropy for Axisymmetric Killing Horizons
(Amer Physical Soc, 2020-12-11)
We show that the gravitational phase space for the near-horizon region of a bifurcate, axisymmetric Killing horizon in any dimension admits a 2D conformal symmetry algebra with central charges proportional to the area. ...
