A Relativistic Entropic Hamiltonian–Lagrangian Approach to the Entropy Production of Spiral Galaxies in Hyperbolic Spacetime

open access: yesUniverse, 2021
Double-spiral galaxies are common in the Universe. It is known that the logarithmic double spiral is a Maximum Entropy geometry in hyperbolic (flat) spacetime that well represents an idealised spiral galaxy, with its central supermassive black hole (SMBH)

Maximum Entropy Production Principle and Morphological Selection in Hydrodynamic Systems

open access: yesProceedings, 2017
In recent decades an idea has emerged that the maximum entropy production principle can be used to select from the different regimes of development of nonequilibrium systems. According to this principle the process with maximum entropy production is most

Training Concept, Evolution Time, and the Maximum Entropy Production Principle

open access: yesEntropy, 2016
The maximum entropy production principle (MEPP) is a type of entropy optimization which demands that complex non-equilibrium systems should organize such that the rate of the entropy production is maximized. Our take on this principle is that to prove or

Maximum Entropy Production Principle for Stock Returns [PDF]

open access: yes2015 IEEE Symposium Series on Computational Intelligence, 2015
In our previous studies we have investigated the structural complexity of time series describing stock returns on New York's and Warsaw's stock exchanges, by employing two estimators of Shannon's entropy rate based on Lempel-Ziv and Context Tree Weighting algorithms, which were originally used for data compression.

Entropy, Closures and Subgrid Modeling

open access: yesEntropy, 2008
Maximum entropy states or statistical mechanical equilibrium solutions have played an important role in the development of a fundamental understanding of turbulence and its role in geophysical flows. In modern general circulation models of the earth’

Energy dissipation mechanism of a centrifugal pump with entropy generation theory

open access: yesAIP Advances, 2021
From the numerical calculations of a common centrifugal pump, the energy loss characteristics have been investigated by applying entropy generation theory to examine the loss due to the direct, turbulence, and wall friction dissipation rates.

Optimizing Our Patients’ Entropy Production as Therapy? Hypotheses Originating from the Physics of Physiology

open access: yesEntropy, 2020
Understanding how nature drives entropy production offers novel insights regarding patient care. Whilst energy is always preserved and energy gradients irreversibly dissipate (thus producing entropy), increasing evidence suggests that they do so in the ...

Maximum entropy PDF projection: A review

open access: yes, 2022
Art. 070001We review maximum entropy (MaxEnt) PDF projection, a method with wide potential applications in statistical inference. The method constructs a sampling distribution for a high-dimensional vector x based on knowing the sampling distribution p(z)
