Lyapunov-based low-energy low-thrust transfers to the Moon
This paper investigates the numerical computation of low-fuel low-thrust Earth-Moon transfers in a full ephemeris model incorporating the gravitational influence of the Sun, the Moon and all planets of the solar system ...
Lyapunov exponents and poles in a non Hermitian dynamics
(Pergamon-Elsevier Science Ltd, 2017-06)
By means of expressing volumes in phase space in terms of traces of quantum operators, a relationship between the poles of the scattering matrix and the Lyapunov exponents in a non Hermitian quantum dynamics, is presented. ...
Rotationally symmetric solutions to the Cahn-Hilliard equation
(Southwest Missouri State University, 2017)
This paper is devoted to construction of new solutions to the Cahn-Hilliard equation in ℝd. Staring from the Delaunay unduloid Dô with parameter τ ∈ (0, τ∗) we find for each sufficiently small ε a solution u of this equation ...
The Multilayer Control Scheme: a strategy to guide n-robots formations with obstacle avoidance
(Springer, 2015-06)
A multilayer scheme is here proposed to implement coordinated control of a group of mobile robots. Specifically, a trajectory tracking controller is proposed to coordinately guide a platoon of robots, with an obstacle ...
