Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.ABSTRACT Hydrogen is a promising carbon‐free fuel but faces challenges due to combustion instability and nitrogen oxide (NOx${\rm NO}_x$) emissions during combustion. This study investigates the potential of blending hydrocarbons (methane, propane) or ammonia with hydrogen‐air flames in order to minimize these challenges.

Artificial Intelligence for Engineering, Volume 1, Issue 2, Page 95-116, 29 December 2025.ABSTRACT This paper presents a tilt–integral–derivative (TID) controller for load–frequency regulation in a two‐area interconnected hybrid microgrid with renewable energy integration. The controller parameters are optimised using the twin delayed deep deterministic policy gradient (TD3) method, an advanced actor‐critic reinforcement learning framework ...

Combustion instability sustained by unsteady vortex combustion [PDF]
, 1985 The determination of an internal feedback mechanism which leads to combustion instability inside a small scale laboratory combustor is presented in this paper. During combustion instability, the experimental findings show that a large vortical structure
