Local null controllability of a quasi-linear system and related numerical experiments
Enrique Fernández-Cara, Juan Límaco, Yuri Thamsten +1
This paper concerns the null control of quasi-linear parabolic systems where the diffusion coefficient depends on the gradient of the state variable. In our main theoretical result…
Topological Thermodynamics of Black Holes: Revisiting the methods of winding numbers calculation
A. A. M. Silva, G. Alencar, C. R. Muniz +2
In this paper, the equivalence between two methods for computing winding numbers is established: the approach of -mapping topological current and the residue method. The methods…
A possible correction of the Saha curve for non-equilibrium states
L. L. Sales, F. C. Carvalho, H. T. C. M. Souza
It is widely known that the Saha equation is not suitable for describing plasmas out of thermodynamic equilibrium. The primordial hydrogen recombination plasma is an example of thi…
Hunting for extra dimensions in black hole shadows
A. S. Lemos, J. A. V. Campos, F. A. Brito
Observational data of the Sagittarius A* (Sgr A*) shadow released by the Event Horizon Telescope (EHT) are used to investigate eventual deviations in the black hole shadow radius,…
Critical behavior of the stochastic SIR model on random bond-diluted lattices
Carlos Handrey A. Ferraz, José Luiz S. Lima
In this paper, we investigate the impact of bond-dilution disorder on the critical behavior of the stochastic SIR model. Monte Carlo simulations were conducted using square lattice…
Auto-Tuning for OpenMP Dynamic Scheduling applied to Full Waveform Inversion
Felipe H. S. da Silva, João B. Fernandes, Idalmis M. Sardina +3
Full Waveform Inversion (FWI) is a widely used method in seismic data processing, capable of estimating models that represent the characteristics of the geological layers of the su…
