prediction of mechanical properties of carbon nanotube-based composite is one of the important issues which should be addressed reasonably. a proper modeling approach is a multi-scale technique starting from nano scale and lasting to macro scale passing in-between scales of micro and meso. the main goal of this research is to develop a multi-scale modeling approach to extract mechanical propert...

A multi-scale modeling approach is proposed in this paper that assists the user in constructing musculoskeletal system models from sub-models describing various mechanisms on different levels on the length scale. In addition, dynamic time-scale analysis has been performed on the developed multi-scale models of various parts of a human limb: on wrist, elbow and shoulder characterized by differen...

dam spillways are the structures that lead rightly and safely the outflow downstream, so that the dam integrity can be guaranteed. many accidents with dams have been caused by an inadequate spillway design or insufficient capacity. to accurately respond the hydraulic spillways, designers use physical modeling for designing this kind of structures. the scale effect in the spillway modeling, as a...

In this note we prove the existence of an inertial manifold, i.e., a global invariant, exponentially attracting, finite-dimensional smooth manifold, for two different sub-grid scale α-models of turbulence: the simplified Bardina model and the modified Leray-α model, in two-dimensional space. That is, we show the existence of an exact rule that parameterizes the dynamics of small spatial scales ...

the aim of this research is to investigate the relationship between leader – member exchange and organizational citizenship behavior, and considering the mediating role of psychological empowerment and organizational commitment. the sample consisted of 250 employees of marun oil and gas producing company who were selected by simple random sampling method. the instruments which used in this rese...
