Vibration Isolation in Stewart Platforms via Phase-Change Low-Melting-Point Alloys for Tunable Stiffness

Aerospace
Micro-vibration mitigation is critical for spacecraft conducting precision-oriented space missions. In this paper, a novel Stewart platform incorporating a phase-change low-melting-point alloy (LMPA) is developed to achieve temperature-dependent ...

Physics Informed Neural Networks for heat conduction with phase change [PDF]

arXiv
We study numerical algorithms to solve a specific Partial Differential Equation (PDE), namely the Stefan problem, using Physics Informed Neural Networks (PINNs). This problem describes the heat propagation in a liquid-solid phase change system. It implies a heat equation and a discontinuity at the interface where the phase change occurs. In the context

Band gap tuning by structural phase transition in Sm-substituted BiFeO3 powders [PDF]

arXiv
The substitution of bismuth by samarium in BiFeO3 is known to induce a structural phase transition from the polar phase to a non-polar phase, with a possible antiferroelectric intermediate structure. In this paper, we investigate the impact of this phase change on the optical properties.
