An Improved Description of the Dielectric Breakdown in Oxides Based on a Generalized Weibull distribution
U. M. S. Costa, V. N. Freire, L. C. Malacarne +4
In this work, we address modal parameter fluctuations in statistical distributions describing charge-to-breakdown and/or time-to-breakdown during the dielectr…
Critical behavior of the 3D-Ising model on a poissonian random lattice
F. W. S. Lima, U. M. S. Costa, R. N. Costa Filho
The single-cluster Monte Carlo algorithm and the reweighting technique are used to simulate the 3D-ferromagnetic Ising model on three dimensional Voronoi-Delaunay lattices. It is a…
Generalized Zipf's Law in proportional voting processes
M. L. Lyra, U. M. S Costa, R. N. Costa Filho +1
Voting data from city-councillors, state and federal deputies elections are analyzed and considered as a response function of a social system with underlying dynamics leading to co…
Fluctuation of energy in the generalized thermostatistics
F. Q. Potiguar, U. M. S. Costa
We calculate the fluctuation of the energy of a system in Tsallis statistics following the finite heat bath canonical ensemble approach. We obtain this fluctuation as the second de…
Thermodynamics arising from Tsallis' thermostatistics
F. Q. Potiguar, U. M. S. Costa
We show, in two different ways, that the Tsallis' partition function and its derivatives are related to thermodynamic quantities such as entropy, internal energy, etc., in the same…
Microscopic analog of temperature within nonextensive thermostatistics
M. P. Almeida, F. Q. Potiguar, U. M. S. Costa
It is presented a microscopic interpretation for the temperature within Tsallis thermostatistics, generalizing the classical derivation based on the Boltzmann-Gibbs statistics. It…
