چکیده

We present a new interpretation of a local framework for information dynamics, including the transfer entropy, by defining a moving frame of reference for the observer of dynamics in lattice systems. This formulation is inspired by the idea of investigating “relativistic” effects on observing the dynamics of information in particular, we investigate a Galilean transformation of the lattice system data. In applying this interpretation to elementary cellular automata, we demonstrate that using a moving frame of reference certainly alters the observed spatiotemporal measurements of information dynamics, yet still returns meaningful results in this context. We find that, as expected, an observer will report coherent spatiotemporal structures that are moving in their frame as information transfer, and structures that are stationary in their frame as information storage. Crucially, the extent to which the shifted frame of reference alters the results depends on whether the shift of frame retains, adds or removes relevant information regarding the source-destination interaction.

Invariance of Fréchet frames under perturbation

Motivating the perturbations of frames in Hilbert and Banach spaces, in this paper we introduce the invariance of Fr'echet frames under perturbation. Also we show that for any Fr'echet spaces, there is a Fr'echet frame and any element in these spaces  has a series expansion.

Investigation of isomorph-invariance in liquid methane by molecular dynamics simulation

In this paper, isomorph invariance of liquid methane is investigated by means of constant-NVT molecular dynamics simulations. According to the data extracted from simulations, equilibrium fluctuations show strong correlation between potential energy U and virial W. We also generated isomorph state points and investigated invariance of certain thermodynamic, structural, and dynamical properties....

Bulk Viscous Bianchi Type VI0 Cosmological Model in the Self-creation Theory of Gravitation and in the General Theory of Relativity

In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...

Evaluation of monitoring network density using discrete entropy theory

The regional evaluation of monitoring stations for water resources can be of great importance due to its role in finding appropriate locations for stations, the maximum gathering of useful information and preventing the accumulation of unnecessary information and ultimately reducing the cost of data collection. Based on the theory of discrete entropy, this study analyzes the density of rain gag...
