We use compatibility of O-plane action with nonlinear T-duality as a guiding principle to find all NS-NS couplings in the O-plane action at order $\\alpha'^2$. We find that the dilaton couplings appear in the string frame only via...

We write the vertex operators of massless NS-NS and RR states of Type II superstring theory in the presence of Orientifold p-planes. They include the usual vertex operators of Type II theory and their images. We then calculate the two...

This paper proposes a “Generalized Iso-Geometrical Analysis” (GIGA) approach to deal with free vibration analysis of plane elasticity problems. The suggested approach which is a generalized form of the well-known isogeometric analysis method uses a...

Full Potential Linear Augmented

Plane Wave (FP-LAPW) and pseudopotential methods. The result shows that, the electronic band

structure and density of state data for SiC in wurtzite and zincblende crystal structures are comparable...

An approximate procedure for determining the elastic critical or buckling loads of plates, subjected to combinations of in-plane loading, is described. The analysis is sufficiently economical in computer requirements to permit parametric studies...

A unified modeling and analysis approach to address the functionally graded plane problems is

suggested which is making use of B-Splines and NURBS for the definition of geometry and material properties as well as the analysis. The recently...
