A mixed semi-analytical cum numerical approach is presented in this paper which accounts for the coupled mechanical and electrical response of piezoelectric, functionally graded (FG) and layered composite hollow circular cylinders of finite length. Under axisymmetric mechanical and electrical loadings, the three-dimensional problem (3D) gets reduced to a two-dimensional (2D) plane strain proble...

1 2 The paper deals with the basic integral equation of random field estimation theory by the criterion of minimum of variance of the error estimate. This integral equation is of the first kind. The corresponding integral operator over a bounded domain Ω in Rn is weakly singular. This operator is an isomorphism between appropriate Sobolev spaces. This is proved by a reduction of the integral eq...

Introduction: The scholarship domains based on Boyer’s definition includes discovery, teaching and learning, application, integration and engagement, but it is a main question that which criteria must a scholarship activities have? In this research, the characteristics of scholarship activities have been studied using a qualitative approach based on higher education experts’ viewpoints from fou...
