Thermal Equilibrium Curves and Turbulent Mixing in Keplerian Accretion Disks [PDF]

open access: yes, 1999
We consider vertical heat transport in Keplerian accretion disks, including the effects of radiation, convection, and turbulent mixing driven by the Balbus-Hawley instability, in astronomical systems ranging from dwarf novae (DNe), and soft X-ray ...

Application of Second Law Analysis in Heat Exchanger Systems

open access: yesEntropy, 2019
In recent decades, the second law of thermodynamics has been commonly applied in analyzing heat exchangers. Many researchers believe that the minimization of entropy generation or exergy losses can be considered as an objective function in designing heat

Entropy-information perspective to radiogenic heat distribution in continental crust [PDF]

open access: yesNonlinear Processes in Geophysics, 2013
Depth distribution of radiogenic heat sources in continental crust is an important parameter that controls its thermal structure as well as the mantle heat flow at the base of continental lithosphere.

Generative Adversarial Networks (GANs): Challenges, Solutions, and Future Directions

open access: yes, 2020
Generative Adversarial Networks (GANs) is a novel class of deep generative models which has recently gained significant attention. GANs learns complex and high-dimensional distributions implicitly over images, audio, and data. However, there exists major

Where there is life there is mind: In support of a strong life-mind continuity thesis [PDF]

open access: yes, 2017
This paper considers questions about continuity and discontinuity between life and mind. It begins by examining such questions from the perspective of the free energy principle (FEP).

Analysis of Entropy Generation Minimization in Circular Porous Fins [PDF]

open access: yesISRN Chemical Engineering, 2012
This work introduces a simple method of exergy analysis in a typical circular porous fin. The entropy generation of any thermodynamic system provides a useful measure of the extent of irreversibility. The irreversibility causes the loss of useful work (exergy) in the system and hence the loss of exergy has to be minimized.
