A Simple Procedure to Extend the Gauss Method of Determining Orbital Parameters from Three to N Points [PDF]
, 2013 A simple procedure is developed to determine orbital elements of an object orbiting in a central force field which contribute more than three independent celestial positions. By manipulation of formal three point Gauss method of orbit determination, an initial set of heliocentric state vectors ${\bf r}_i$ and $\dot{\bf{r}}_i$ is calculated.

Back to the Future: Estimating Initial Globular Cluster Masses from their Present Day Stellar Mass Functions [PDF]
, 2015 We use N-body simulations to model the 12 Gyr evolution of a suite of star clusters with identical initial stellar mass functions over a range of initial cluster masses, sizes, and orbits. Our models reproduce the distribution of present-day global stellar mass functions that is observed in the Milky Way globular cluster population.

A Method to Determine BeiDou GEO/IGSO Orbital Maneuver Time Periods
Sensors, 2019 Because there are different types of BeiDou constellations with participating geostationary orbit (GEO) and inclined geosynchronous orbit (IGSO) satellites, the maneuvering frequency of BeiDou satellites is higher than that of other navigation systems ...

Multi-Map Orbit Hopping Chaotic Stream Cipher [PDF]
arXiv, 2006 In this paper we propose a multi-map orbit hopping chaotic stream cipher that utilizes the idea of spread spectrum mechanism for secure digital communications and fundamental chaos characteristics of mixing, unpredictable, and extremely sensitive to initial conditions.

Periodic Orbit Scar in Propagation of Wavepacket [PDF]
arXiv, 2017 This study analyzed the scar-like localization in the time-average of a timeevolving wavepacket on the desymmetrized stadium billiard. When a wavepacket is launched along the orbits, it emerges on classical unstable periodic orbits as a scar in the stationary states.
