Convolution, aggregation and attention based deep neural networks for accelerating simulations in mechanics
Saurabh Deshpande, Raúl I. Sosa, Stéphane P. A. Bordas +1
Deep learning surrogate models are being increasingly used in accelerating scientific simulations as a replacement for costly conventional numerical techniques. However, their use…
Multistability of globally coupled Duffing oscillators
Raúl I. Sosa, Damián H. Zanette
We analyze the collective dynamics of an ensemble of globally coupled, externally forced, identical mechanical oscillators with cubic nonlinearity. Focus is put on solutions where…
Lévy copulas: a probabilistic point of view
Ayi Ajavon
There is a one-to-one correspondence between Lévy copulas and proper copulas. The correspondence relies on a relationship between Lévy copulas sitting on and max-id…
Energy flow and dissipation in heterogeneous ensembles of coupled phase oscillators
Raúl I. Sosa, Damián H. Zanette
We present analytical expressions and numerical results for the rates of energy exchange between oscillators and with the environment in a heterogeneous ensemble of globally couple…
