We describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. We present a new method for computing, electronic transport wave function and Greens function of the disordered Graphene. In this method, based on the small rectangular approximation, break up the potential barriers in to small parts. Then using the f...

Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...

Conventional quaternion based methods have been extensively employed for spacecraft attitude control where the aerodynamic forces can be neglected. In the presence of aerodynamic forces, the flight attitude control is more complicated due to aerodynamic moments and inertia uncertainties. In this paper, a robust nero-adaptive quat...

The correlation function (r) of matter in the non-linear regime is assumed to be determined by the density prooles (r) and the mass distribution n(M) of virialized halos. The Press{Schechter approach is used to compute n(M), and the stable clustering hypothesis is used to determine the density prooles of these Press{Schechter halos. Thus, the shape and amplitude of (r) on small scales is relate...

Wave diffraction is a very important phenomenon in marine engineering and several models have been developed for its simulation. The new version of SWAN, a third generation spectral model, includes an approximation to wave diffraction. The approximation is based on the mild-slope equation for refraction and diffraction, omitting phase information. The objective this paper is to evaluate the per...

A light scattering model under the Rayleigh-Gans-Debye approximation has been developed for polycristalline alumina. The model states that transmittance of dense alumina ceramics basically depends not only on the maximum grain size but also on the preferential orientation of their c-axis, or texture. The effect of texture in transparency has been experimentally measured on several dense alumina...

The correlation function ξ(r) of matter in the non-linear regime is assumed to be determined by the density profiles ρ(r) and the mass distribution n(M) of virialized halos. The Press–Schechter approach is used to compute n(M), and the stable clustering hypothesis is used to determine the density profiles of these Press–Schechter halos. Thus, the shape and amplitude of ξ(r) on small scales is r...
