During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

Abstract: The dynamics simulation of complex railway vehicles requires a dedicated vehicle model, such as multi-body dynamics model. However, the multi-body model is time-consuming in long-distance ...

Abstract: Integrated energy systems face challenges such as inconsistent equipment parameters, unmeasurable data, and complex coupling mechanisms. To address these issues, this paper develops an ...
