Generalized quantum entropies [PDF]

Physics Letters A, 2011
يتم اشتقاق خصم الإنتروبيا الكمومية المعممة داخل أطر تساليس وكانياداكيس باستخدام تعميم المعامل متعدد الحدود العادي. يعتمد هذا التعميم على الضرب والقسمة المشوهة المعنية. نظهر أن الانتروبيا المذكورة أعلاه تتسق مع تلك المفترضة بشكل تعسفي في سياقات أخرى.

Dynamical study of spinodal decomposition in heavy ion collisions

, 2005
Nuclei undergo a phase transition in nuclear reactions according to a caloric curve determined by the amount of entropy. Here, the generation of entropy is studied in relation to the size of the nuclear system.Comment: 4 pages, 2 figures, Contributed ...

Analysis of NO Formation and Entropy Generation in a Reactive Flow

Aerospace, 2022
A comprehensive investigation of turbulent combustion is accomplished to study the relationship between nitrogen oxide (NO) formation and entropy generation distribution in a non-premixed propane combustion. The radiation heat transfer and combustion are

Entropy Generation in MHD Flow of a Uniformly Stretched Vertical Permeable Surface under Oscillatory Suction Velocity [PDF]

, 2009
This paper reports the analytical calculation of the entropy generation due to heat and mass transfer and fluid friction in steady state of a uniformly stretched vertical permeable surface with heat and mass diffusive walls, by solving analytically the ...

Black Hole Tunneling Entropy and the Spectrum of Gravity [PDF]

, 1992
The tunneling approach for entropy generation in quantum gravity is applied to black holes. The area entropy is recovered and shown to count only a tiny fraction of the black hole degeneracy.

Entropy Generation and Heat Transfer Performances of Al2O3-Water Nanofluid Transitional Flow in Rectangular Channels with Dimples and Protrusions

Entropy, 2016
Nanofluid has great potentials in heat transfer enhancement and entropy generation decrease as an effective cooling medium. Effects of Al2O3-water nanofluid flow on entropy generation and heat transfer performance in a rectangular conventional channel ...

Effects of a classical homogeneous gravitational field on the cavity-field entropy and generation of the Schrodinger-cat states in the Jaynes-Cummings model

, 2007
In this paper, we examine the effects of the gravitational field on the dynamical evolution of the cavity-field entropy and the creation of the Schrodinger-cat state in the Jaynes-Cummings model.

Entropy Generation Analysis of Desalination Technologies [PDF]

, 2011
Increasing global demand for fresh water is driving the development and implementation of a wide variety of seawater desalination technologies. Entropy generation analysis, and specifically, Second Law efficiency, is an important tool for illustrating ...

Generalized Maximum Entropy [PDF]

AIP Conference Proceedings, 2005
A long standing mystery in using Maximum Entropy (MaxEnt) is how to deal with constraints whose values are uncertain. This situation arises when constraint values are estimated from data, because of finite sample sizes. One approach to this problem, advocated by E.T.
