Number of Information and its Relation to the Cosmological Constant Resulting from Landauer’s Principle [PDF]
, 2013 Using a recent published formula for the number of information N that results from Landauer’s principle we obtain an expression for the cosmological constant Λ .

Enhancing Extractable Quantum Entropy in Vacuum-Based Quantum Random Number Generator
Entropy, 2018 Information-theoretically provable unique true random numbers, which cannot be correlated or controlled by an attacker, can be generated based on quantum measurement of vacuum state and universal-hashing randomness extraction.

A new entropy based on a group-theoretical structure [PDF]
, 2015 A multi-parametric version of the nonadditive entropy $S_{q}$ is introduced. This new entropic form, denoted by $S_{a,b,r}$, possesses many interesting statistical properties, and it reduces to the entropy $S_q$ for $b=0$, $a=r:=1-q$ (hence Boltzmann ...

Free Convection and Irreversibility Analysis inside a Circular Porous Enclosure
Entropy, 2003 We investigate the nature of heat transfer and entropy generation for natural convection in a two-dimensional circular section enclosure. The enclosure is assumed to fill with porous media.

Entropy Generation Minimization Theoretical Analysis for External Flow Around Horizontal Cylinder at low Reynold Number [PDF]
Engineering and Technology Journal, 2018 The minimization of entropy generation is a helpful method to design optimum thermal system, and find an expression for entropy generation at several ranges of Reynolds number for heat transfer and friction flow irreversibility is a good way to achieve ...
