Distribution function of fusion reaction products and entropy evolution

Mostacci, D.; Molinari, V.; Pizzio, F. - In: Physica A: Statistical Mechanics and its Applications 385 (2007) 1, pp. 161-169

One of the outcomes of nuclear reactions is that reaction products have at birth distribution functions far from Maxwellian. What role do those distribution functions play in the evolution of the entropy of the system? The purpose of this work is to show the effect of the distribution functions...

Pathway model, superstatistics, Tsallis statistics, and a generalized measure of entropy

Mathai, A.M.; Haubold, H.J. - In: Physica A: Statistical Mechanics and its Applications 375 (2007) 1, pp. 110-122

) 317–328] is shown to be inferable from the maximization of a certain generalized entropy measure. This entropy is a … variant of the generalized entropy of order α, considered in Mathai and Rathie [Basic Concepts in Information Theory and … associated with Shannon, Boltzmann–Gibbs, Rényi, Tsallis, and Havrda–Charvát entropies. The generalized entropy measure …

Legendre structure of the thermostatistics theory based on the Sharma–Taneja–Mittal entropy

Scarfone, A.M. - In: Physica A: Statistical Mechanics and its Applications 365 (2006) 1, pp. 63-70

The statistical proprieties of complex systems can differ deeply for those of classical systems governed by Boltzmann–Gibbs entropy. In particular, the probability distribution function observed in several complex systems shows a power-law behavior in the tail which disagrees with the standard...

On the statistical interpretation of generalized entropies

Figueiredo, Annibal; Antônio Amato, Marco; Marciano da … - In: Physica A: Statistical Mechanics and its Applications 367 (2006) C, pp. 191-206

We present a direct generalization of the Boltzmann counting method to define a generic form for a generalized entropy …. This form is based on the probabilities of sequences of a stochastic process. Usual forms of generalized entropy can be …

A κ-entropic approach to the analysis of the fracture problem

Cravero, M; Iabichino, G; Kaniadakis, G; Miraldi, E; … - In: Physica A: Statistical Mechanics and its Applications 340 (2004) 1, pp. 410-417

In order to study the relation between the ohmic resistance measured in a thin conducting ribbon and the length of a transversal cut, we employ a one-parameter deformed exponential and logarithm that were recently introduced (Phys. Rev. E 66 (2002) 056125) in the framework of a generalized...

Generalized Hausdorff inverse moment problem

Pintarelli, María B.; Vericat, Fernando - In: Physica A: Statistical Mechanics and its Applications 324 (2003) 3, pp. 568-588

We consider a generalization of Hausdorff moment problem in which the inputs are generalized moments defined by μαn≡∫01xn[f(x)]αdx(n=1,2,…) where α is a real number and f(x) is the probability density function to be determined. The necessary and sufficient conditions for the existence...

Matsuba, Ikuo; Takahashi, Hiroshi - In: Physica A: Statistical Mechanics and its Applications 319 (2003) C, pp. 458-468

Employing the generalized entropy introduced by Tsallis, we propose a new method to estimate the scaling index of the …

Trends in Earnings Inequality among Young Adults

Zandvakili, Sourushe - In: Review of Social Economy 60 (2002) 1, pp. 93-107

The initial stage of labor market activity for young adults influences their labor market engagement and earnings profiles over their life cycle. I examine earnings inequality among young adults in a dynamic setting. Education, marital status, race are contributors to the observed earnings...

Gravothermal catastrophe and Tsallis’ generalized entropy of self-gravitating systems

Taruya, Atsushi; Sakagami, Masa-aki - In: Physica A: Statistical Mechanics and its Applications 307 (2002) 1, pp. 185-206

We present a first physical application of Tsallis’ generalized entropy to the thermodynamics of self …-point analysis. The results give an important suggestion that the Tsallis’ generalized entropy is indeed applicable and viable to the …-space distribution function. In contrast to previous analyses using the Boltzmann–Gibbs entropy, we apply the Tsallis-type generalized …
