Conservation Laws and Dynamics of Solitons to the Multicomponent Fractional Gross–Pitaevskii System: Application in the Bose–Einstein Condensation

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this work, we study the β‐fractional multicomponent Gross–Pitaevskii (G–P) system, which plays an important role in modeling Bose–Einstein condensates (BECs) and propagation in nonlinear waves. In Bose–Einstein condensation, the G–P equation is of great importance as it describes the condensate wave function’s behavior.

Influence of Velocity Feedback Time Delay on the Nonlinear Dynamic Characteristics of Maglev Trains Under Unsteady Aerodynamic Forces

International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 707-720, December 2025.
ABSTRACT Time delays frequently arise in active control systems due to sensor sampling, signal transmission, and actuator response, making their effects on system dynamics non‐negligible. This paper investigates how velocity feedback time delay influences the nonlinear dynamic characteristics of a maglev train subjected to unsteady aerodynamic forces ...

A NEW HUMAN-COMPUTER-INTERFACE FOR HIGH-SPEED-MAGLEV TRAIN TRAFFIC SUPERVISION

IFAC Proceedings Volumes, 1995
Abstract In modern high speed train traffic high capacity and acceptance of the transport system becomes more and more important. Human Computer Interfaces nowdays used in train traffic control are developed historically and do not fit any longer as the real traffic situation is difficult to perceive by the dispatcher.
