Symmetry, Invariant Manifolds and Flow Reversals in Active Nematic Turbulence
Angel Naranjo, Rumayel Pallock, Caleb Wagner +1
We investigate how symmetry, exact coherent structures (ECSs), and their invariant manifolds organize spontaneous flow reversals in a 2D active nematic confined to a periodic chann…

A Data-Driven, Energy-based Approach for Identifying Equations of Motion in Vibrating Structures Directly from Measurements
Cristian López, Aryan Singh, Ãngel Naranjo +1
Determining the underlying equations of motion and parameter values for vibrating structures is of great concern in science and engineering. This work introduces a new data-driven…

Weak-form modified sparse identification of nonlinear dynamics
Cristian López, Ãngel Naranjo, Diego Salazar +1
Identifying nonlinear dynamics and characterizing noise from data is critical across science and engineering for understanding and modeling the behavior of the systems accurately.…
