Reduced-space Gaussian Process Regression for Data-Driven Probabilistic Forecast of Chaotic Dynamical Systems
Zhong Yi Wan, Themistoklis P. Sapsis
We formulate a reduced-order strategy for efficiently forecasting complex high-dimensional dynamical systems entirely based on data streams. The first step of our method involves r…
Reduced-order prediction of rogue waves in two-dimensional deep-water waves
Mohammad Farazmand, Themistoklis P. Sapsis
We consider the problem of large wave prediction in two-dimensional water waves. Such waves form due to the synergistic effect of dispersive mixing of smaller wave groups and the a…
Heavy-tailed response of structural systems subjected to stochastic excitation containing extreme forcing events
Han Kyul Joo, Mustafa A. Mohamad, Themistoklis P. Sapsis
We characterize the complex, heavy-tailed probability distribution functions (pdf) describing the response and its local extrema for structural systems subjected to random forcing…
Energy exchange and localization in essentially nonlinear oscillatory systems: canonical formalism
O. V. Gendelman, T. P. Sapsis
Over recent years, a lot of progress has been achieved in understanding of the relationship between localization and transport of energy in essentially nonlinear oscillatory system…
Dynamical indicators for the prediction of bursting phenomena in high-dimensional systems
Mohammad Farazmand, Themistoklis Sapsis
Drawing upon the bursting mechanism in slow-fast systems, we propose indicators for the prediction of such rare extreme events which do not require a priori known slow and fast coo…
