Investigation of the Free-Fall Dynamic Behavior of a Rectangular Wing with Variable Center of Mass Location and Variable Moment of Inertia

open access: yesAerospace, 2023
In recent years, the air-drop launch technology of near-space UAVs has attracted much attention. Between downfall from the carrier and the flight control system’s initiation, the UAV presents free-fall movement.

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

open access: yesJASA 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: yesJournal 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

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.

Experimental Evidence for a Structural-Dynamical Transition in Trajectory Space [PDF]

open access: yes, 2017
Among the key insights into the glass transition has been the identification of a non-equilibrium phase transition in trajectory space which reveals phase coexistence between the normal supercooled liquid (active phase) and a glassy state (inactive phase)
