Experimental investigation on preconditioned rate induced tipping in a thermoacoustic system

Abstract Many systems found in nature are susceptible to tipping, where they can shift from one stable dynamical state to another. This shift in dynamics can be unfavorable in systems found in various fields ranging from ecology to finance. Hence, it is important to identify the factors that can lea...
