Phase trajectory entropy: A promising tool for passive diver detection [PDF]

open access: diamondJASA Express Letters, 2021
Passive diver detection is really significant as it constitutes a potential real-time monitoring of serious underwater threats. Up to now, there is still a lack of an efficient approach to characterize the complexity and fickleness with non-parametric ...

Quantum particle trajectories and geometric phase [PDF]

open access: greenJournal of Experimental and Theoretical Physics Letters, 2000
"Particle"-trajectories are defined as integrable $dx_ dp^ = 0$ paths in projective space. Quantum states evolving on such trajectories, open or closed, do not delocalise in $(x, p)$ projection, the phase associated with the trajectories being related to the geometric (Berry) phase and the Classical Mechanics action. High Energy Physics properties of

Dynamical Temperature from the Phase Space Trajectory

open access: diamondHungarian Journal of Industry and Chemistry, 2017
In classical statistical mechanics the trajectory in phase space represents the propagation of a classical Hamiltonian system. While trajectories play a key role in chaotic system theory, exploitation of a single trajectory has yet to be considered. This

Trajectory Generation for Stair Ascent Walking using Rayleigh Oscillator [PDF]

open access: yes, 2013
This paper describes a trajectory generation technique for stair-ascent walking. The knee, hip and ankle joint trajectory during stair ascent are generated using mutually coupled, nonlinear oscillators.
