binaloud mountains formed during collision of iran and turan plate in the late triassic time and caused shortening of the sedimentary cover because of cimmerian and alpine orogeny. the thrust sheets with different generations formed as a results of the binalood and alborz fold- thrust belts. northeast of iran that was already south coast of the divergent margin of the paleothetys ocean at this ...

An overview of the related topics of anomalous coarsening and glassy dynamics is given. In anomalous coarsening, the typical domain size of an ordered phase grows more slowly with time than the power law dependence that is usually observed, for example, in magnetic systems. We discuss how anomlaous coarsening may arise through domain-size dependent energy barriers in the coarsening process. We ...

A theory is developed of concurrent growth and coarsening of a dispersion of spheres that accounts for the exchange of heat by diffusion among the spheres due to their curvature differences and between the spheres and the environment due to an externally imposed heat extraction rate. The results show that in concurrent growth and coarsening the average particle radius asymptotically increases w...

We present a wavelet analysis of coarsening of mounds during molecular beam epitaxy. The advantage in using wavelets over Fourier analysis is that one can track the coarsening process in both, location (direct space) and frequency (or scale) space at the same time. The wavelets concise scale decomposition allows the discrimination of the coarsening process, i.e. tracking coarsening at different...

The driving force for coarsening is provided by the excess interfacial free energy. In a system with isotropic interface energies, classical coarsening theories can predict the evolution of the sizes of spherical crystals. However, if the interfaces are anisotropic, crystal growth and shrinkage may be limited by the surface attachment/detachment rate, the motion of ledges, or the nucleation of ...

A uniform finite element mesh rarely provides the best discretization of a domain to accommodate a solution with both optimal efficiency and minimal error. Mesh adaptation can approach a more optimal solution by accommodating regions of the mesh with higher or lower element density. Extensive attention has been given to mesh adaptation in both computational mechanics and computer graphics to pr...

Diffusion-controlled coarsening (Ostwald ripening) of precipitated Solutions is studied by numerical Simulation. An algorithm is devised which exploits the screening of solute concentration fields, thereby removing the restriction to small Systems of previous work. Simulation of the coarsening of 5000 droplets at 10% volume fraction reveals long-ranged dynamical correlations which broaden the d...

We discuss the nonlinear dynamics and fluctuations of interfaces with bending rigidity under the competing attractions of two walls with arbitrary permeabilities. This system mimics the dynamics of confined membranes. We use a two-dimensional hydrodynamic model, where membranes are effectively one-dimensional objects. In a previous work [T. Le Goff et al., Phys. Rev. E 90, 032114 (2014)], we ha...
