Rate of relaxation for a mean-field zero-range process
نویسنده
چکیده
We introduce a mean-field zero-range process. It is a Markov chain model for a microcanonical ensemble. We prove that the process converges to a fluid limit. The fluid limit rapidly relaxes to the appropriate Gibbs distribution.

Spectral gap for the zero range process with constant rate
We solve an open problem concerning the relaxation time (inverse spectral gap) of the zero range process in Z/LZ with constant rate, proving an upper bound of O((ρ + 1)L), where ρ is the density of particles.
متن کاملDesign of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...

In order to investigate the effect of an electromagnetic field and ultrasonic waves on the seed germination of Cuminum cyminum that two separate experiments using a completely randomized design with four replications was conducted at Seed Science and Technology Laboratory of Faculty Agricultural Sciences, the Shahed University of Tehran in 2012. In the first experiment, for the seeds of zero, 1...
متن کاملInteraction Between Precipitation and Dynamic Recrystallization in HSLA-100 Microalloyed Steel
Strain induced precipitation in HSLA-100 steel was investigated by conducting hotcompression and relaxation tests at temperature range of 850°C to 1100°C and strain rate of 0.001s-1 to 1s-1. The absence of dynamic recrystallization at temperatures below 1000°C was attributedto the influence of dynamic precipitation. The stress relaxation tests showed that strain inducedprecipitation is possible...
