The computation of finite-time Lyapunov exponents on unstructured meshes and for non-Euclidean manifolds
(American Institute of Physics, 2010-03-01)We generalize the concepts of finite-time Lyapunov exponent (FTLE) and Lagrangian coherent structures to arbitrary Riemannian manifolds. The methods are illustrated for convection cells on cylinders and Moumlbius strips, ... -
Detecting dynamical boundaries from kinematic data in biomechanics
(American Institute of Physics, 2010-03-01)Ridges in the state space distribution of finite-time Lyapunov exponents can be used to locate dynamical boundaries. We describe a method for obtaining dynamical boundaries using only trajectories reconstructed from time ...
