Plane Waves and Penrose Limits

Numerical microlocal analysis of 2-D noisy harmonic plane and circular waves

We present a mathematical and numerical analysis of the stability and accuracy of the NMLA (Numerical MicroLocal Analysis) method [2] and its discretization. We restrict to homogeneous space and focus on the two simplest cases : 1) Noisy plane wave packets, 2) Noisy point source solutions. A stability result is obtained through the introduction of a new ”impedance” observable. The analysis of t...

Reflection and Transmission of Plane Waves at Micropolar Piezothermoelastic Solids

The present investigation analysis a problem of r­­­eflection and transmission at an interface of two micropolar orthotropic piezothermoelastic media. The basic equations and constitutive relations for micropolar orthotropic piezothermoelastic media for G-L theory are derived. The expressions for amplitude ratios corresponding to reflected and transmitted waves are derived analytically. The eff...

Algebraic Theta Functions and Eisenstein-kronecker Numbers

In this paper, we give an overview of our previous paper concerning the investigation of the algebraic and p-adic properties of Eisenstein-Kronecker numbers using Mumford’s theory of algebraic theta functions.

a contrastive study of rhetorical functions of citation in iranian and international elt scopus journals

writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
