Thermo-elastic analysis of a functionally graded hollow sphere is carried out and numerical solutions of displacement, stress and thermal fields are obtained using the Polynomial differential quadrature (PDQ) method. Material properties are assumed to be graded in the radial direction according to a power law function, ho...

The diffusive coarsening of 2D soap froths is governed by von Neumann's law. A statistical version of this law for dry 3D foams has long been conjectured. A new derivation, based on a theorem by Minkowski, yields an explicit analytical von Neumann's law in 3D which is in very good agreement with detailed simulations and experiments. The average growth rate of a bubble with F faces is shown to b...

COMPUTING IN SCIENCE & ENGINEERING Semiconductors are indispensable to the modern economy. The semiconductor— through its synchronous increase in power and decline in price—has contributed significantly to the United States’ economic growth over the past decade.1,2 The technological advances spurred by this regular and predictable rate of growth in power (as described by Moore’s law) have enhan...

This paper presents an information-boundaries perspective on the family and the Internet with the aim of helping to set the context for child development in the new media environment. Drawing from family studies, sociology, and communication, it lays out a model for viewing the family in relation to the Web. The paper draws research ideas out of the framework that center on four areas: family c...

Some preliminaries about the integrable families of Riccati equations and solutions structure of these equations in several cases are presented in this paper, then by using of definitions for fractional derivative we apply the new extended of tanh method to the perturbed nonlinear fractional Schrodinger equation with the kerr law nonlinearity. Finally by using of this method and solutions of Ri...

Following the observations of the self-similarity in various length scales in the roughness of the fractured solid surfaces, we propose here a new model for the earthquake. We demonstrate rigorously that the contact area distribution between two fractal surfaces follows an unique power law. This is then utilised to show that the elastic energy releases for slips between two rough fractal surfac...
