Stochastic generalization for a hyperbolic model of spinodal decomposition

Galenko, P.K.; Kharchenko, Dmitrii; Lysenko, Irina - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 17, pp. 3443-3455

A model for diffusion and phase separation which takes into account exponential relaxation of the solute diffusion flux and its fluctuations is developed. The model describes a system undergoing phase separation governed by a partial differential equation of hyperbolic type. The analysis is done...

Asymptotic expansions in mean and covariance structure analysis

Ogasawara, Haruhiko - In: Journal of Multivariate Analysis 100 (2009) 5, pp. 902-912

Asymptotic expansions of the distributions of parameter estimators in mean and covariance structures are derived. The parameters may be common to, or specific in means and covariances of observable variables. The means are possibly structured by the common/specific parameters. First, the...

Scattering from multicomponent charged ramified polymeric networks of arbitrary topology

Ghaouar, N.; Benhamou, M.; Gharbi, A. - In: Physica A: Statistical Mechanics and its Applications 359 (2006) C, pp. 267-288

The scattering and critical properties of weakly charged ramified polymeric systems for any arbitrary topology are investigated by using the random phase approximation. The interaction matrix is modeled as the sum of the short-range excluded volume matrix and the long-range Debye–Hûckel...

New method of determining the structure factor of real liquids and their mixtures using ultrasonic velocity

Kalidoss, M.; Ravi, S. - In: Physica A: Statistical Mechanics and its Applications 312 (2002) 1, pp. 59-69

For the first time the structure factors S(Q) for nine pure liquids and 20 binary mixtures have been studied using experimental ultrasonic velocity. The packing factor η on which S(Q) solely depends on (while adopting hard sphere model) is estimated with the help of the experimental ultrasonic...
