Wigner Trajectory Characteristics in Phase Space and Field Theory [PDF]

open access: yes, 1998
Exact characteristic trajectories are specified for the time-propagating Wigner phase-space distribution function. They are especially simple---indeed, classical---for the quantized simple harmonic oscillator, which serves as the underpinning of the ...

An Algorithm for Painting Large Objects Based on a Nine-Axis UR5 Robotic Manipulator

open access: yesApplied Sciences, 2022
An algorithm for automatically planning trajectories designed for painting large objects is proposed in this paper to eliminate the difficulty of painting large objects and ensure their surface quality.

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)

Constraints Maintaining Mesh Refinement Method for Solving Whole Trajectory of Discontinuous Aerodynamics

open access: yesIEEE Access, 2023
Solving trajectories of multi-phase dynamic advanced vehicles is difficult due to the coexistence of discontinuous aerodynamics, long-range and multi-peak features.

Canonical formalism for the Born-Infeld particle [PDF]

open access: yes, 1998
In the previous paper (hep-th/9712161) it was shown that the nonlinear Born-Infeld field equations supplemented by the "dynamical condition" (certain boundary condition for the field along the particle's trajectory) define perfectly deterministic theory,

Accelerating dual cardiac phase images using undersampled radial phase encoding trajectories [PDF]

open access: yesMagnetic Resonance Imaging, 2016
A three-dimensional dual-cardiac-phase (3D-DCP) scan has been proposed to acquire two data sets of the whole heart and great vessels during the end-diastolic and end-systolic cardiac phases in a single free-breathing scan. This method has shown accurate assessment of cardiac anatomy and function but is limited by long acquisition times.

The unified control strategy for planar Acrobot and Pendubot

open access: yesShenzhen Daxue xuebao. Ligong ban, 2023
For the planar Acrobot and Pendubot with passive joints at different positions, a control strategy based on trajectory planning and tracking control is proposed to achieve their unified control. The whole control process is divided into two phases.

Caustic design in periodic lattices [PDF]

open access: yes, 2012
We study curved trajectory dynamics and design in discrete array settings. We find that beams with power law phases produce curved caustics associated with the fold and cusp type catastrophes.
