Stochastic resonance at nonequilibrium phase transitions

Skokov, V.N.; Koverda, V.P.; Vinogradov, A.V.; … - In: Physica A: Statistical Mechanics and its Applications 430 (2015) C, pp. 65-72

Thermal pulsations in a transition from a nucleate to a film regime of water boiling on a wire heater with a periodic Joule heat release have been studied experimentally. At frequencies of the periodic action smaller than 0.1 Hz the intermittency of the nucleate and film boiling regimes was...

Maximum entropy in a nonlinear system with a 1/f power spectrum

Koverda, V.P.; Skokov, V.N. - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 1, pp. 21-28

there exist different probability distribution functions with power-law (non-Gaussian) and Gaussian tails. The governing … equation of a system has a probability distribution function with Gaussian tails. Therefore, distribution functions for … spectrum. The Tsallis entropy and the Renyi entropy for the probability distribution functions with power-law tails have been …

1/f oscillations in a model of moth populations oriented by diffusive pheromones

Barbosa, L.A.; Martins, M.L.; Lima, E.R. - In: Physica A: Statistical Mechanics and its Applications 345 (2005) 1, pp. 143-158

An individual-based model for the population dynamics of Spodoptera frugiperda in a homogeneous environment is proposed. The model involves moths feeding plants, mating through an anemotaxis search (i.e., oriented by odor dispersed in a current of air), and dying due to resource competition or...

Phase transition and 1/f noise in a computer network model

Liu, Feng; Shan, Xiuming; Ren, Yong; Zhang, Jun - In: Physica A: Statistical Mechanics and its Applications 328 (2003) 3, pp. 341-350

Using a simple cellular automaton model of data packets transport in the Internet, the travel times of data packets and transport rates of routers along a fixed path are studied. In this model the additive increasing of transport rates, extraneous random interferences and finite capacity of...

Boltzmann power laws

Saiz, A. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 2, pp. 225-236

In this paper we propose a model based on the Boltzmann distribution as a mechanism for generating power laws, Boltzmann Power Laws (BPL). Some of these power laws are studied and compared to popular power laws such as ‘1/f’ noise and self-organized criticality (SOC). We will show how, in...

Stochastic resonance and 1/f noise at coupled phase transitions

Koverda, V.P.; Skokov, V.N. - In: Physica A: Statistical Mechanics and its Applications 393 (2014) C, pp. 173-181

The system of two nonlinear stochastic equations simulating 1/f fluctuations during the interaction of nonequilibrium phase transitions in the presence of an external periodic action has been studied by numerical methods. It is shown that in the system there appears stochastic resonance, which...

Novel analytical and numerical approach to modeling low-frequency noise in semiconductor devices

da Silva, Roberto; Wirth, Gilson I.; Brederlow, Ralf - In: Physica A: Statistical Mechanics and its Applications 362 (2006) 2, pp. 277-288

In this work, based on robust experimental results, we derive a novel theoretical probabilistic approach to model the low-frequency noise power S(f) in semiconductor devices. Using the proposed approach we obtained, analytically, the average of the integrated noise power Wp=∫fLfHS(f)df as a...
