The Coupled Orbit-Attitude Dynamics and Control of Electric Sail in Displaced Solar Orbits [PDF]
Displaced solar orbits for spacecraft propelled by electric sails are investigated. Since the propulsive thrust is induced by the sail attitude, the orbital and attitude dynamics of electric-sail-based spacecraft are coupled and required to be ...

Neural Network based Fault Tolerant LQR Control for Orbital Maneuvering in LEO Satellites using Hall Effect Thrusters [PDF]
This paper develops a neural network-based fault tolerant LQR control for orbital maneuvering of satellites in low altitude orbit that are subjected to disturbances like earth gravity, atmospheric drag, third body, and solar radiation.

Some Special Types of Orbits around Jupiter
This paper intends to show some special types of orbits around Jupiter based on the mean element theory, including stationary orbits, sun-synchronous orbits, orbits at the critical inclination, and repeating ground track orbits.

Research on real-time reachability evaluation for reentry vehicles based on fuzzy learning
Accurate and rapid prediction of reentry trajectory and landing point is the basis to ensure the reentry vehicle recovery and rescue, but it has high requirements for the continuity and stability of real-time monitoring and positioning data and the ...

TOG Proteins Are Spatially Regulated by Rac-GSK3β to Control Interphase Microtubule Dynamics. [PDF]
Microtubules are regulated by a diverse set of proteins that localize to microtubule plus ends (+TIPs) where they regulate dynamic instability and mediate interactions with the cell cortex, actin filaments, and organelles.

Ferrimagnetic Dynamics Induced by Spin‐Orbit Torques
Ferrimagnets are the magnetic materials with the fastest current‐induced dynamics reported so far. Among them, rare‐earth transition‐metal (RE‐TM) alloys offer a fertile playground for studying the behavior of multi‐sublattice systems with tunable ...

On the global dynamics of periodic triangular maps [PDF]
This paper is an extension of an earlier paper that dealt with global dynamics in autonomous triangular maps. In the current paper, we extend the results on global dynamics of autonomous triangular maps to periodic non-autonomous triangular maps. We show
