Information Equation of State [PDF]

open access: yesEntropy, 2008
Landauer’s principle is applied to information in the universe. Once stars began forming there was a constant information energy density as the increasing proportion of matter at high stellar temperatures exactly compensated for the expanding ...

The Equation of State of Biogas [PDF]

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
The presented work deals with a state behavior of real gas, biogas. Theoretical approach was utilized for processing of this work. Compressibility factor was calculated with help of two equation of state – Van der Waals equation and Redlich‑Kwong ...

Chemical potential of a Lennard Jones fluid [PDF]

open access: yesSerbian Astronomical Journal, 2010
The aim of this paper is to present results of analytical calculation of chemical potential of a Lennard Jones (LJ) fluid performed in two ways: by using the thermodynamical formalism and the formalism of statistical mechanics.

A new method for studying the problem of optimal dynamic measurement in the presence of observation interference

open access: yesMeasurement: Sensors, 2021
This paper describes a new method for studying the problem of optimal dynamic measurement in the framework of a new paradigm of dynamic measurements. This paradigm is based, on the one hand, on the automatic control model theory to describe the model of ...

Forecast of Airblast Vibrations Induced by Blasting Using Support Vector Regression Optimized by the Grasshopper Optimization (SVR-GO) Technique

open access: yesApplied Sciences, 2022
Air overpressure (AOp) is an undesirable environmental effect of blasting. To date, a variety of empirical equations have been developed to forecast this phenomenon and prevent its negative impacts with accuracy. However, the accuracy of these methods is

Finite-temperature equation of state with hyperons [PDF]

open access: yesEPJ Web of Conferences, 2022
We present the novel finite-temperature FSU2H* equation-of-state model that covers a wide range of temperatures and lepton fractions for the conditions in proto-neutron stars, neutron star mergers and supernovae.

Revisiting Barrow's graduated inflationary universe: A warm perspective

open access: yesPhysics Letters B, 2022
It is presumed that thermal fluctuations present during inflationary epoch can make inflaton scalar field to interact with other fields resulting in the existence of a thermal component during the inflationary period.

Hyperons in Neutron Stars

open access: yesUniverse, 2021
I review the issues related to the appearance of hyperons in neutron star matter, focusing in particular on the problem of the maximum mass supported by hyperonic equations of state. I discuss the general mechanism that leads to the formation of hyperons
