Time delay embeddings to characterize the timbre of musical instruments using Topological Data Analysis: a study on synthetic and real data
Gakusei Sato, Hiroya Nakao, Riccardo Muolo
Timbre allows us to distinguish between sounds even when they share the same pitch and loudness, playing an important role in music, instrument recognition, and speech. Traditional…
Synchronization of nonlinearly coupled Stuart-Landau oscillators on networks
Wilfried Segnou, Riccardo Muolo, Marie Dorchain +2
The dynamics of coupled Stuart-Landau oscillators play a central role in the study of synchronization phenomena. Previous works have focused on linearly coupled oscillators in diff…
Optimal interaction functions realizing higher-order Kuramoto dynamics with arbitrary limit-cycle oscillators
Norihisa Namura, Riccardo Muolo, Hiroya Nakao
The Kuramoto model is the simplest case of globally coupled phase oscillators with a purely sinusoidal fundamental-harmonic phase coupling function, whose dynamical properties have…
Flutter Suppression Enhancement in Coupled Nonlinear Airfoils with Intermittent Mixed Interactions
Qi Liu, Riccardo Muolo, Hiroya Nakao +1
Flutter suppression facilitates the improvement of structural reliability to ensure the flight safety of an aircraft. In this study, we propose a novel strategy for enlarging ampli…
Synchronization of Dirac-Bianconi driven oscillators
Riccardo Muolo, Iván León, Yuzuru Kato +1
In dynamical systems on networks, one assigns the dynamics to nodes, which are then coupled via links. This approach does not account for group interactions and dynamics on links a…
Chimera states on m-directed hypergraphs
Rommel Tchinda Djeudjo, Timoteo Carletti, Hiroya Nakao +1
Chimera states are synchronization patterns in which coherent and incoherent regions coexist in systems of identical oscillators. This elusive phenomenon has attracted significant…
