The evolutionary mechanism of information negentropy spurred by emergencies [PDF]

open access: yesScientific Reports
In the context of social system resilience, the role of information negentropy—a measure of order and structural stability—remains underexplored during emergencies.

Invariance Properties of the Entropy Production, and the Entropic Pairing of Inertial Frames of Reference by Shear-Flow Systems [PDF]

open access: yesEntropy, 2021
This study examines the invariance properties of the thermodynamic entropy production in its global (integral), local (differential), bilinear, and macroscopic formulations, including dimensional scaling, invariance to fixed displacements, rotations or ...

New Negentropy Optimization Schemes for Blind Signal Extraction of Complex Valued Sources [PDF]

open access: yesRadioengineering, 2015
Blind signal extraction, a hot issue in the field of communication signal processing, aims to retrieve the sources through the optimization of contrast functions.

Friction, Free Axes of Rotation and Entropy

open access: yesEntropy, 2017
Friction forces acting on rotators may promote their alignment and therefore eliminate degrees of freedom in their movement. The alignment of rotators by friction force was shown by experiments performed with different spinners, demonstrating how ...

Energy from Negentropy of Non-Cahotic Systems [PDF]

open access: yesEntropy, 2018
Negative contribution of entropy (negentropy) of a non-cahotic system, representing the potential of work, is a source of energy that can be transferred to an internal or inserted subsystem. In this case, the system loses order and its entropy increases.

Negentropy in Many-Body Quantum Systems [PDF]

open access: yesEntropy, 2016
Negentropy (negative entropy) is the negative contribution to the total entropy of correlated many-body environments. Negentropy can play a role in transferring its related stored mobilizable energy to colliding nuclei that participate in spontaneous or ...

Cascades and Dissipative Anomalies in Compressible Fluid Turbulence

open access: yesPhysical Review X, 2018
We investigate dissipative anomalies in a turbulent fluid governed by the compressible Navier-Stokes equation. We follow an exact approach pioneered by Onsager, which we explain as a nonperturbative application of the principle of renormalization-group ...

Negentropy Spectrum Decomposition and Its Application in Compound Fault Diagnosis of Rolling Bearing [PDF]

open access: yesEntropy, 2019
The rolling bearings often suffer from compound fault in practice. Compared with single fault, compound fault contains multiple fault features that are coupled together and make it difficult to detect and extract all fault features by traditional methods

Multi-Objective Informative Frequency Band Selection Based on Negentropy-Induced Grey Wolf Optimizer for Fault Diagnosis of Rolling Element Bearings [PDF]

open access: yesSensors, 2020
Informative frequency band (IFB) selection is a challenging task in envelope analysis for the localized fault detection of rolling element bearings. In previous studies, it was often conducted with a single indicator, such as kurtosis, etc., to guide the

Negentropy-Based Sparsity-Promoting Reconstruction with Fast Iterative Solution from Noisy Measurements [PDF]

open access: yesSensors, 2020
Compressed sensing provides an elegant framework for recovering sparse signals from compressed measurements. This paper addresses the problem of sparse signal reconstruction from compressed measurements that is more robust to complex, especially non ...
