Longitudinal as well as transverse dynamics of a molten salt beyond the hydrodynamic region is studied within the generalized collective modes (GCM) approach. An analytical three-variable model is applied to the treatment of the coupled longand short-time charge fluctuations. Dispersion laws of propagating kinetic collective excitations such as optic phonon-like modes, heat and shear waves are ...

behaviour of the dilution characteristics of the coastal waters off tuticorin is presented in thebackground of setting up of a desalination plant. simulations of dispersion and spreading of the proposeddischarges has been carried out. scenarios of dilutions were assessed based on the results of a 2d model using the advection-dispersion theory. it is observed that under prevailing currents in th...

The equivalent circuit model for artificial magnetic materials based on various arrangements of split rings is generalized by taking into account losses in the substrate or matrix material. It is shown that a modification is needed to the known macroscopic permeability function in order to correctly describe these materials. Depending on the dominating loss mechanism (conductive losses in metal...

Generalized linear models are a widely used method to obtain parametric estimates for the mean function. They have been further extended to allow the relationship between the mean function and the covariates to be more flexible via generalized additive models. However, the fixed variance structure can in many cases be too restrictive. The extended quasilikelihood (EQL) framework allows for esti...

Chaotic mode-locking of chirped-pulse oscillator has been analyzed on the basis of generalized nonlinear cubic-quintic complex Ginzburg-Landau equation. It has been shown, that the chirped solitary pulse can be stabilized against the vacuum excitation, if the fourth-order dispersion is nonzero and positive. However, the pulse evolves chaotically, if the dispersion reaches some threshold value.

The dispersion of polaritons of symmetry Aj and E is investigated in the region of four isotopic vibrations originating from C13and N15-atoms in their natural abundances. The measured dispersion curves are explained in terms of a theory for localized mode polaritons (LMP) developed by Ohtaka. The dispersion relation is generalized for a polyatomic crystal and applied to K3Cu(CN)4 . The comparis...

Generalized estimating equations (GEE) fit parameters based on sums of weighted residuals, which may be applied for example to the Poisson distribution. We discuss Generalized Poisson (GP) response data. This distribution has a more flexible variance function than the Poisson distribution and has an additional dispersion parameter. To fit this parameter, second level estimating equations based ...

We report the results of our study on the role of microfluidic infiltration technique in improving the coupling characteristics of dual-core photonic crystal fiber (PCF) couplers. Using the finite element method (FEM), we evaluate the effective mode area, dispersion and coupling parameters of an infiltrated dual-core PCF. We use these parameters to design a compact and reconfigurable coupler by...

Much interest has focused on the regression problem with censored data, which has usefulness In biological, pharmaceutical, industrial, survival, and failure time experiments. In these last three applications, the usual assumption is that data after a suitable transformation follow a normal, extreme value, or other distribution. Although usual methods of analysis have traditionally assumed cons...
