Damage spreading in random field systems

, 1997
We investigate how a quenched random field influences the damage spreading transition in kinetic Ising models. To this end we generalize a recent master equation approach and derive an effective field theory for damage spreading in random field systems ...

Random Access for Underwater Acoustic Cellular Systems

Sensors, 2018
In this paper, a random access preamble (RAP) design technique for underwater acoustic cellular systems is proposed. After showing that the conventional RAP used in long term evolution (LTE) systems is not appropriate for underwater acoustic cellular ...

Density Matrix Renormalization Group Method for the Random Quantum One-Dimensional Systems - Application to the Random Spin-1/2 Antiferromagnetic Heisenberg Chain -

, 1996
The density matrix renormalization group method is generalized to one dimensional random systems. Using this method, the energy gap distribution of the spin-1/2 random antiferromagnetic Heisenberg chain is calculated.

Randomized Authentication Systems [PDF]

, 2007
In this work, the application of Luby-Rackoff randomizers for authentication purposes is examined. First randomized authentication codes are introduced. In these codes, the assignment of a cryptogram to a given message is done in two stages. In the first, the redundancy is introduced and in the second, the concatenation of several Luby-Rackoff ...

Comments on "On the Stability of Random Systems" [PDF]

, 1960
Dr. Samuels [1] is to be congratulated on a most interesting paper. It is unfortunate that a number of errors appear in Sec.

Reliability Analysis of Random Fuzzy Unrepairable Systems

Discrete Dynamics in Nature and Society, 2014
The lifetimes of components in unrepairable systems are considered as random fuzzy variables since randomness and fuzziness are often merged with each other.

The narrow recurrence of random dynamical systems [PDF]

Mathematica Bohemica
Let $(\Omega,\mathcal{F},\mathbb{P})$ be a probability space, where $\mathcal{F}$ is countably generated, and $X$ be a Polish space. Let $\varphi$ be a random dynamical system with time $\mathbb{T}$ on $X$.

Emergent symmetry in Brownian SYK models and charge dependent scrambling

Journal of High Energy Physics, 2022
In this work, we introduce a symmetry-based approach to study the scrambling and operator dynamics of Brownian SYK models at large finite N and in the infinite N limit.

Anosov C-systems and random number generators

, 2016
We are developing further our earlier suggestion to use hyperbolic Anosov C-systems for the Monte-Carlo simulations in high energy particle physics. The hyperbolic dynamical systems have homogeneous instability of all trajectories and as such they have ...

Synchronization of Chaotic Systems by Common Random Forcing [PDF]

, 1999
We show two examples of noise--induced synchronization. We study a 1-d map and the Lorenz systems, both in the chaotic region. For each system we give numerical evidence that the addition of a (common) random noise, of large enough intensity, to ...
