ChaosNetBench: Benchmarking Spatio-Temporal Graph Neural Networks on Chaotic Lattice Dynamics
Henok Tenaw Moges, Charalampos Skokos, Deshendran Moodley
Spatio-temporal graph neural networks (STGNNs) are widely used for short-term forecasting in dynamic physical systems such as traffic and weather. However, the prevailing evaluatio…
A lightweight Spatial-Temporal Graph Neural Network for Long-term Time Series Forecasting
Henok Tenaw Moges, Deshendran Moodley
We propose Lite-STGNN, a lightweight spatial-temporal graph neural network for long-term multivariate forecasting that integrates decomposition-based temporal modeling with learnab…
Hamiltonian Chaos: From Galactic Dynamics to Plasma Physics
Henok Tenaw Moges
The primary focus of this thesis is the numerical investigation of chaos in Hamiltonian models describing charged particle orbits in plasma, star motions in barred galaxies, and or…
On the behavior of the Generalized Alignment Index (GALI) method for dissipative systems
Henok Tenaw Moges, Thanos Manos, Ovidiu Racoveanu +1
The behavior of the Generalized Alignment Index (GALI) method has been extensively studied and successfully applied for the detection of chaotic motion in conservative Hamiltonian…
The evolution of the phase space structure along pitchfork and period-doubling bifurcations in a 3D galactic bar potential
Henok Tenaw Moges, Matthaios Katsanikas, Panos Patsis +2
We investigate how the phase space structure of a 3D autonomous Hamiltonian system evolves across a series of successive 2D and 3D pitchfork and period-doubling bifurcations, as th…
Anomalous diffusion in single and coupled standard maps with extensive chaotic phase spaces
Henok Tenaw Moges, Thanos Manos, Charalampos Skokos
We investigate the long-term diffusion transport and chaos properties of single and coupled standard maps. We consider model parameters that are known to induce anomalous diffusion…
Investigating Chaos by the Generalized Alignment Index (GALI) Method
Henok Tenaw Moges
One of the fundamental tasks in the study of dynamical systems is the discrimination between regular and chaotic behavior. Over the years several methods of chaos detection have be…
On the behavior of the Generalized Alignment Index (GALI) method for regular motion in multidimensional Hamiltonian systems
Henok Moges, Thanos Manos, Charalampos Skokos
We investigate the behavior of the Generalized Alignment Index of order (GALI) for regular orbits of multidimensional Hamiltonian systems. The GALI is an efficient chao…
