Untangling Binary Trees via Rotations
In this paper we present a polynomial time algorithm for finding the shortest sequence of rotations that converts one binary tree into another when both binary trees are of a restricted form. The initial tree must be a degenerate tree, where every node has exactly one child, and the destination binary tree must also be degenerate, of a more restricted nature. Previous work on rotation distance ...

متن کاملAsteroid Capture Using a Binary Exchange Mechanism
A new method of capturing an asteroid in an orbit around the Earth is proposed, inspired by the theory that the irregular satellites of Jupiter and Neptune may have at one time been members of a binary asteroid. After a close approach with the planet, the binary asteroid was disrupted, and one member was captured into a permanent orbit. A parametric study was conducted by simulating binary-Eart...
متن کاملSpacecraft Dynamics near a Binary Asteroid
We study a simple model for an asteroid pair, namely a planar system consisting of a rigid body and a sphere. This model is interesting because it is one of the simplest that captures the coupling between rotational and translational dynamics. By assuming that the binary is in a relative equilibria of the system, we construct a model for the motion of a spacecraft about this asteroid pair witho...
متن کامل3 - Dimensional Reconstruction of Asteroid
Introduction: The OSIRIS [1] imaging experiment of the Rosetta spacecraft will image comet 67P/Churyumov-Gerasimenko in 2014-2015. During its journey, OSIRIS has imaged asteroid 2867 Steins on 5 September 2008. The fly-by was successful and returned more than 100 resolved images of the body as shown on Figure 1 [2]. The diamond’s shape of the body is remarkable. The surface presents several sma...
