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

, 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 ...

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

IEEE 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.

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

Magnetic 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.

Canonical formalism for the Born-Infeld particle [PDF]

, 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,

The unified control strategy for planar Acrobot and Pendubot

Shenzhen 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.
