Safe landing area determination for a Moon lander by reachability analysis

open access: yes, 2016
In the last decades developments in space technology paved the way to more challenging missions like asteroid mining, space tourism and human expansion into the Solar System. These missions result in difficult tasks such as guidance schemes for re-entry,

Properties of Conflict Free and Persistent Petri Nets

open access: yes, 1975
Petri nets have been extensively studied because of their suitabi1ity as models for asynchronous computing. Despite this effort, the mathematical properties of Petri nets are not very well understood.

Feasibility regions of boundary value problems of low-thrust trajectories

open access: yes, 2016
Two types of boundary values problems of low-thrust trajectories are considered: the position matching problem and the reachability problem. We perform experiments on three approaches to solve and to analyze such boundary value problems, particularly the
