We present a complete Lie symmetry analysis of the one-dimensional proper-time formulation of Maxwell’s equations with velocity-dependent propagation speed b=√c²+u². Through systematic application of symmetry methods, we: 1) classify all Lie point symmetries of the system, 2) derive exact invariant solutions via symmetry r...

We present a Lie symmetry classification of 2D proper-time Maxwell’s equations, deriving an 8-dimensional Lie algebra and constructing rotationally invariant Bessel function solutions and self-similar solutions with Hadamard regularization. A central-difference/Verlet scheme is stable under the standard Courant condition for numerical solutions. The results model transverse plasma waves in relativistic jets and particle beams in plasma wakefield accelerators [1], preserving causality via  ,...

In view of the control problem of hydrogen pressure and flow coupling in the anode subsystem of the Proton Exchange Membrane Fuel Cell (PEMFC) under dynamic load conditions, this paper proposes an intelligent control framework based on the deep deterministic policy gradient (DDPG) algorithm. Firstly, a dynamic model of the fuel cell anode system is established to transform the multivariable coupling control problem into a reinforcement learning state space; secondly, a multi-objective reward fun...

The economic dispatch problem in power systems is a classic issue in the field of power systems. This paper first uses the traditional genetic algorithm to solve the economic dispatch problem of power systems. The simulation results show that the classic genetic algorithm falls into the dilemma of local minimum values. Therefore, we introduce a multi-population genetic algorithm, setting different crossover and mutation probabilities in different populations, and introducing an immigration opera...
